What is a full spectrum LED

The full spectrum refers to the spectrum curve that includes ultraviolet, visible, and infrared light in the spectrum, and the ratio of red, green, and blue in the visible part is similar to that of sunlight, and the color rendering index Ra is close to 100.

What is a full spectrum LED

The spectrum of sunlight can be called the full spectrum, and the color temperature changes with the four seasons and the time of morning and evening. Therefore, the spectrum of the full spectrum lamp should change the color temperature successively with the change of time, and simulate the natural light environment in order to be more in line with the natural growth laws of organisms.

The continuous spectrum of solar radiation at noon on a sunny day, with a color temperature of 5000K, is divided into two parts: visible light and invisible light. The wavelength of visible light is 400-760 nm, and it is divided into 7 colors: red, orange, yellow, green, cyan, blue, and purple, which are concentrated as white light; there are two types of invisible light, infrared with wavelengths greater than 760 nm and ultraviolet rays with wavelengths of 290-400 nm.

The blue light spectrum in ordinary LEDs is relatively high, and it lacks violet, cyan, short-wave green, and long-wave red parts. At present, full-spectrum LEDs are realized by chips + phosphors. By adding purple chips or adding between the blue peak and the phosphor peak. Phosphors with wavelengths in the recessed region are used to complement the spectrum.

The color rendering ability of a light source to an object is called color rendering. The color rendering index of sunlight is defined as 100. The closer the color rendering index (Ra) value is to 100, the better the color rendering.

15 sample colors are used to evaluate the color rendering of the light source. The special color rendering R9 is an indicator of the reproduction quality of the vivid red color of the LED. The higher values ??of Ra and R9 are the performance of high-quality LEDs.

Compared with ordinary LEDs, full-spectrum LEDs have a more continuous spectrum and wider color gamut; the color rendering index Ra is greatly improved, closer to 100; the special color rendering index R9 can be as high as 90 or more.

Features and Benefits of LED Grow Lights

LED plant growth lights use LEDs as luminous bodies, which can provide the required light conditions for plant photosynthesis in an environment lacking sunlight so that plants can grow and develop normally or better. LED lights to have the functions of strengthening roots, promoting, adjusting flowering period and color, promoting fruit ripening and coloring, and improving taste and quality.

Features and Benefits of LED Grow Lights

In recent years, new LED lighting technology has developed rapidly. As the fourth-generation new lighting source, LED has many different characteristics from other electric light sources, which makes it the first choice for energy-saving and environmentally friendly light sources.

Compared to the previous three similar products, LED grow lights are more powerful, efficient, and less expensive, they save electricity and generate less heat. Less heat can bring the grow light closer to the plants without worrying about the plants being scorched. Because of this, LED lights can effectively promote better plant growth, so LED grows lights are widely adopted around the world.

LED grow lights also have the following characteristics: rich in wavelength types, which are exactly in line with the spectral range of plant photosynthesis and photo morphology; the half-width of the spectral wave is narrow, which can be combined to obtain pure monochromatic light and composite spectrum as required; it can concentrate the light balance of specific wavelengths It can not only regulate the flowering and fruiting of crops, but also control the plant height and plant nutrients; the system generates less heat and occupies less space, and can be used in a multi-layer cultivation three-dimensional combination system to achieve low heat load and miniaturization of production space.

The advantages of LED light sources are high luminous efficiency, long service life, safety and reliability, environmental protection, and energy saving, so the prospect of LED in the lighting market will be more concerned.

Simmtronic and Mackwell collaborate on emergency lighting and control technology

Advances in LED performance have driven very compact emergency lighting solutions. The partnership has been crafted with expertise in their respective fields to create unparalleled designs that deliver unprecedented value to end users and solution installers.

Simmtronic and Mackwell collaborate on emergency lighting and control technology

The partnership marks the launch of the “Universal Sensor with Integrated Emergency Light”, a configuration that combines Simmtronic’s market-leading sensor technology with Mackwell’s XY-Fi emergency module (the world’s smallest emergency luminaire and is recently won the Electrical Industry Award of the Year).

By combining emergency lighting and a PIR sensor in a single enclosure, significant savings in money, time, and labor can be achieved in the field due to reduced clutter, installation costs, project programming, and cleaner space aesthetics.

The solution includes a range of single-point mounting solutions for three different types: flush, surface, and boom. The designs are aesthetically matched and physically integrated with the existing Simmtronic control sensor design and installation.

UK manufacturers Mackwell and Simmtronic are both available for site visits, demonstrations, and training. Simmtronic also offers assembly services.

“We have been trying to combine the two technologies into one combined product for years, as the presence detectors are spaced similar to standalone emergency light fittings. This was not possible until Mackwell released the new small LED emergency light fittings, but now I am pleased to confirm that by working together we have taken it to the next level and set a new standard – creating the only combined emergency lighting sensor,” said Mario Costanzo, Director of Simmtronic. “It’s a powerful tool with simple solutions and we can’t wait to introduce it to the UK’s architecture and engineering community.”

“We are proud of this innovation because we realized that the XY-Fi optics are perfectly matched to the Simmtronic sensor optics and therefore have the same spacing in the building,” said Mackwell Commercial Director Rene Joppi. “The best of both worlds in one installation.”

The partnership will also ensure that Simmtronic’s DALI automated emergency testing solutions work in tandem with Mackwell’s range of emergency illuminators, exit signs, and OEM conversion solutions, ensuring full compatibility between the company’s products.

Can led lights fill plants with light?

LED is a good fill light in plant growth. After correction, it can stimulate the root system by enhancing blue light, promoting photosynthesis, and ensuring peak growth, so as to meet the requirements of indoor plants. They also release a small amount of heat.

Can led lights fill plants with light?

1. LED plant growth light is a kind of light source using a semiconductor light source, which is specially used on crops such as flowers and vegetables. It becomes worse and worse because of the lack of light. Through the illumination of LED lights, it can not only accelerate the growth of plants, but also increase the flowering period of flowers and increase the quality of flowers. The application of this system in greenhouses, greenhouses, and other facilities can, on the one hand, overcome the shortcomings of the lack of light in the greenhouses that cause the quality of greenhouse vegetables such as tomatoes and cucumbers to decrease, and on the other hand, it can also advance the eggplant vegetables in the greenhouse to the market before and after the Spring Festival. So as to achieve the purpose of off-season cultivation.

2. The function of the fill light is that the fill light can provide a certain amount of lighting on cloudy days or when there is no one to shine for a long time. However, I would like to remind you: fill light is fill light, not a substitute for the sun. If you can replace the sun, it is a “replacement light”.

3. Many people said that the effect of this fill light is not very good. In fact, there is a big problem with the way he uses the lights. It does not need to be used continuously for 10 hours indoors, and it does not need to be turned on suddenly for several hours outdoors, and it can also does not to turned on within 24 hours. The correct way is to open at dawn and close within 2-3 hours at night. Plants also have their own schedules. In addition, the reflective sheet is especially important, which can provide the refraction of light. Plus the issue of distance. The spacing between different lights and plants is also different.

UV-LED light, can disinfect the new coronavirus and HIV

UV-LED lamps generally refer to LEDs with a central wavelength of light emission below 400 nm, but sometimes when the light emission wavelength is greater than 380 nm, it is called a near-ultraviolet LED, and when it is less than 300 nm, it is called a far-ultraviolet LED. Due to the high sterilization effect of short-wavelength light, UV LEDs are often used in biomedical, anti-counterfeiting identification, purification (water, air, etc.) fields, computer data storage, and military.

UV-LED light, can disinfect the new coronavirus and HIV

Based on the characteristics of UV-LED lamps, in the latest study, scientists from the University of Toronto’s Scarborough campus found that the use of UV-LED lamps can destroy the coronavirus and HIV. The lamp can alternate between white light and germicidal ultraviolet (UV) light. With inexpensive retrofits, they can also be used in many standard lighting fixtures, bringing a “unique appeal” to public spaces, said Christina Guzzo, senior author of the study.

The researchers first tested the lamp on bacterial spores (Bacillus pumilus spores), which are known for their resistance to this radiation. “If you can kill these spores, then you can reasonably say that you should be able to kill most other viruses that you routinely encounter in the environment,” the researchers said, showing that within 20 seconds of UV exposure, the spores The growth rate decreased by 99%.

The researchers then created droplets containing the coronavirus or HIV to simulate the typical way people encounter the virus in public, such as from coughing and sneezing. The droplets were then exposed to UV light and placed in culture to see if any virus remained active. After just 30 seconds of exposure, the virus’s ability to infect was reduced by 93 percent.

When testing different concentrations of the virus, they found that samples with more viral particles were more resistant to UV light. But even with this high viral load, infectivity dropped by 88%. In addition, the researchers compared UV light to two heavy-duty disinfectants used in laboratory studies, and they found that the lamps had similar effects in their ability to inactivate viruses.

Of course, while the antibacterial potential of UV-LED lamps in the air has long been established, however, its widespread use in public spaces is limited – broad-spectrum UVC light in the wavelength range between 200 and 400 nanometers (nm) destroys the The molecular bonds that hold DNA together can be very effective at killing bacteria and viruses. This conventional UV light is commonly used to sterilize surgical equipment. But traditional germicidal UV light also harms human health and can cause skin cancer and cataracts, hindering its use in public spaces.

In response, the research team is working with Safe Antivirus Technologies to develop a unique UV-LED lighting module. With motion sensors, the lights automatically switch to UV light when no one is in the room, then switch back to normal light when there is movement.

In 2022, the output value of the lighting LED market will exceed 8.1 billion US dollars

Governments around the world have higher and higher requirements for energy saving. It is expected that the output value of the lighting LED market will opportunity to reach 8.11 billion US dollars in 2022, a year-on-year increase of 9.2%. In the next few years, the lighting LED market size will continue to grow driven by factors such as human-centric lighting (HCL), smart lighting, etc., and is expected to reach US$11.1 billion by 2026, with a compound annual growth rate from 2021 to 2026 (CAGR) was 8.4%.

In 2022, the output value of the lighting LED market will exceed 8.1 billion US dollars

Despite the continued impact of the epidemic in 2022, the popularity of vaccines and the recovery of economic activity, coupled with the rigid demand of the lighting market as a daily necessity, the global “carbon neutrality” and the growing demand in recent years, the energy-saving agenda has prompted many major countries to increase Measures such as energy efficiency and low-carbon heating achieve net-zero emissions. Lighting is the main energy consumer in buildings, accounting for 20%-30% of total building energy consumption. Driven by the upgrade of aging equipment, the penetration rate of LED will continue to increase. In addition, smart lighting can also achieve the purpose of timely energy saving.

The gradual recovery of the lighting market is clearly reflected in the 2021 vendor revenue rankings. MLS, the leading manufacturer of lighting LEDs, ranks first by revenue with a 34% revenue growth rate in 2021.

In terms of pricing, the demand in the lighting industry will gradually pick up in 2021. In the face of the demand for higher specification end-use products and the impact of rising raw materials and comprehensive operating costs, LED packaging factories will no longer adopt pricing strategies to seize additional market share and allow the lighting of LED products. Pricing stabilizes and picks up in 2021. From the perspective of product categories, the annual growth rate of 2835LED, 3030LED, and 5630LED is 2.1%-4.4%. The market price of high-power lighting LED products (above 1 watt) such as ceramic substrate LED and 7070LED has an average annual increase of 3%-6%.

LED explosion-proof lights have passed the most stringent international certification

Since the beginning of the 21st century, with the rapid development of my country’s petroleum, chemical, mining, and other industries, lighting fixtures have become more and more widely used in production, storage, and rescue, with more and more varieties. It is particularly important to prevent the accidental explosion of lighting fixtures in explosive gas dangerous places.

LED explosion-proof lights have passed the most stringent international certification

According to reports, the LED explosion-proof lamps produced by ENELTEC can at least reduce power consumption by more than 80% compared with traditional explosion-proof lighting, and save more than 80% of electricity expenses.

“Because most of the original components and materials of this project can be recycled and reused, and do not contain harmful or toxic substances, it has a good protective effect on the ecological environment and greatly improves the comprehensive recycling and reuse of resources.” said the chairman of ENELTEC.

According to reports, over the years, ENELTEC has established a strong technical team and achieved many scientific research results with the development of a green economy, the realization of energy saving and emission reduction goals, and the creation of a world-renowned brand of explosion-proof lamps as its own responsibility.

The chairman of ENELTEC said, “Our company has high- and intermediate-level professor-level technical and scientific research talents.

Problems that need to be avoided when purchasing LED lamps

With the continuous innovation of LED technology, LED lighting products have been widely used in lighting fields such as home, office, and public facilities construction. Now LED lights have propped up half of the lighting industry. Under the trend of replacement of LED lights, the replacement of traditional light tubes with LED tubes has gradually become a trend. So, what is the current LED lamp market situation? What is its optoelectronic performance? Is the safety performance up to standard?

Problems that need to be avoided when purchasing LED lamps

We have specially planned the in-depth evaluation of the LED T8 1.2m tube in this issue. We have purchased a total of five LED T8 1.2m tubes from Philips, 3 well-known domestic lighting brands, and a non-brand manufacturer from the lighting market, and invited a third-party testing agency. –Shenzhen Nanfang Lixun Testing Co., Ltd. reveals the real performance of LED lamps currently on the market from the aspects of optoelectronic performance and safety and provides a reference for consumers to buy LED lamps.

We all know that one of the most intuitive parameters that reflect the energy-saving and high-efficiency characteristics of LED lighting products is luminous efficiency. The calculation formula is the ratio of total luminous flux to total power, and the unit is lumens/watt (lm/w). Generally speaking, the higher the luminous efficiency, the stronger the ability of the lighting fixture to convert electrical energy into light energy, that is, the stronger the energy saving of the lighting fixture under the condition of providing the same brightness; under the same power, the lighting of the lighting fixture The stronger the sex, the greater the brightness.

Through the comparison of various parameters, consumers can be more targeted when purchasing LED T8 lamps. First of all, due to the risk of electric shock, brand B, brand C, and brand D products should be excluded first when purchasing. In addition, among the remaining two LED T8 lamp products, Philips has more advantages in light efficiency, which also means that the product has higher lighting efficiency and more energy saving. It should be noted that although brand A products have more advantages in terms of price, they do not meet IEC standards in terms of safety, so consumers also need to be cautious in purchasing.

At present, the world is still in the stage of LED lamps replacing traditional lamps, and China has become the most important manufacturing base for LED lamps. While the industry is prosperous and developed, the safety of LED lamps has not attracted widespread attention. Due to the internal electrical connection between the two ends of the pins of some double-ended LED lamps, when one end of the double-ended LED lamp is inserted into a live lamp socket, the other floating end will be charged. In practical application, since the installation user often cannot tell whether the light switch has cut off the power supply when one end of the double-ended LED light is inserted, the charged pin at the other end may cause an electric shock to the installer, which will cause electric shock injury and additional injury of human fall.

In the authoritative International Electrotechnical Commission (IEC) standard IEC 62776, this safety requirement is called: Pin-safety during insertion (the safety of the lamp pin during insertion). In the IEC62776 standard, there are clear specifications and requirements for the safety of the lamp pin when the double-ended LED lamp is inserted into the lamp. Because the formulation of relevant safety standards in our country lags behind that of IEC, my country has not yet issued a national standard for the safety of LED lamps, and there is no way to regulate the safety of the pins of LED lamps when they are inserted.

In addition, it is not difficult to find through comparison that domestic brands have more or less hidden dangers in terms of safety, mainly due to the lack of relevant domestic safety standards and the lack of consumers’ knowledge of LED lighting safety. We also hope that the country can issue relevant safety standards as soon as possible to standardize products on the market and avoid potential safety hazards because the safety of consumers’ lives and property is priceless!

LED light pole screen is an important front-end entrance for smart city information collection

In recent years, with the introduction of the concept of smart citiesLED light pole screen is an important front-end entrance for smart city information collection, many cities in my country have set off a wave of building smart cities. Subsequently, the “14th Five-Year Plan Outline” was issued, which pointed out the construction of smart cities and digital villages, boosting urban and rural development and innovation of governance models with digitalization, and comprehensively improving operational efficiency and livability. As an important “role” in the construction of smart cities, smart street lights can be expected to have a lot of room for development, and LED light pole screens, as important supporting equipment, will usher in greater opportunities.

 

In the process of building a smart city, it is actually not difficult to find. Smart street lights are like a huge “spider web”, which can be described as “extending in all directions” and can be effectively integrated into various environments of the city. As an important information release terminal, the LED light pole screen plays a more important role in this “spider web”: it uses the advantages of “interconnection of all things”, plus its own functions and other functions, as the information for building a smart city. Important front-end entry for acquisition.

It is worth mentioning that the LED light pole screen has been implemented in more scenarios through the intelligent trend, and it is slowly covering the old and old traditional information dissemination methods and gradually becoming the mainstream application of information dissemination in the era of wisdom. Taking the LED light pole screen as the main entry point, using its precise market positioning and unique innovative perspective, it is further integrated into the smart street light and smart city construction phalanx.

Of course, LED light pole screens are not only outstanding in smart construction. With the introduction and advocacy of a series of national policies, LED light pole screens, as a carrier with more compatibility and scalability, are supporting street light poles. The application form of the smart city is well known to the public, and with the popularization of the concept of building a smart city around the world, the overseas application market is gradually expanding.

It can be seen that the LED light pole screen has created a new way of intelligent construction information transmission with its own advantages. Under the current boom of smart city construction, with the common development of smart street lights + LED light pole screens, it is not difficult to predict that the application market of LED light pole screens will reach a new high.

LED Lighting: The Best ‘Atmosphere Group’ for the Winter Olympics

During the Beijing Winter Olympics, the beautiful LED screen won people’s attention. In contrast, LED lighting-related products have become the behind-the-scenes heroes of all aspects of the Beijing Winter Olympics, and have played an important role in the guarantee and atmosphere of the event.

LED Lighting: The Best 'Atmosphere Group' for the Winter Olympics

The lighting difficulty of the Winter Olympics events was originally higher than that of the Summer Olympics – the events are played on ice or snow, and there will be reflections or overexposure. The lighting should fully consider the visual experience of the live audience and the viewing experience of the TV audience. Olympic Broadcasting Service (OBS) CEO Ianis Exarks said that the Beijing Winter Olympics used UHD and HDR technology for the first time, and used ultra-high-definition and high-dynamic-range 4K technology to shoot, produce and broadcast event programs. The stroboscopic indicators of lighting in the venues of the Winter Olympics put forward higher requirements.

On the basis of flexibility, high efficiency, and energy-saving, in order to ensure the effectiveness of the event, each venue of the Beijing Winter Olympics has customized a set of lighting solutions, which can meet the different lighting needs of various events such as event preparation, event execution, and awards.

For example, Signify is responsible for the design and supply of lighting systems for major Winter Olympics venues, including the Capital Gymnasium. As a competition venue for figure skating and speed skating, Capital Gymnasium adopts Philips LED sports lighting products and Interact Sports intelligent interconnected lighting system. Visual effects to create a better viewing experience. Its lighting products have high color reproduction and support flicker-free ultra-slow-motion playback, which can meet the stringent ultra-high-definition broadcast requirements of international events, and allow TV viewers around the world to experience clearer and more realistic events experience.

In addition, the arrangement of the lighting system on the snow project is also quite ingenious. “Snow Dragon”, the venue of the National Snowmobile Sled Center in the Yanqing Division of the Beijing Winter Olympics, has undertaken the “F1 Formula Racing” project in the ice and snow sports – the snowmobile sled race. In order to present this excellent track, the lighting supplier of “Snow Dragon”, Horsai, fully considered the glaring energy and glare effect of the white snow track, color rendering index reaches Ra≥90, R9≥45 or high-definition display index TLCI11 Qa≥85, a light source with light efficiency greater than 90lm/W, creating a light source with more uniform and transparent light, no flicker, low-temperature resistance, and uniform brightness as well as the “anti-glare green lighting system”, it has been certified by OBS, BSF (International Snowmobile Association), and FIL (International Luge Association), providing a comfortable competitive track for athletes from all over the world while meeting the broadcast of ultra-high-definition cameras need.
