Six tips for led kitchen lighting

 

Home the concept of depth, the kitchen is not just for cooking fires, rooms, open kitchen, semi-open kitchen, all kinds of people dizzying, even the master to show the personality of a space. Therefore, the installation of lighting and lighting of the kitchen more and more particular about today, Xiao Bian share of led kitchen lighting six know-how with you.

 

1 kitchen lighting system should be set adjustable time when the feeling of dim lighting or glare, can be adjusted, people will feel more comfortable, more at ease.

 

2 led kitchen lighting’s color temperature should be consistent with the room’s atmosphere, at least with the other areas of the color temperature of the room.

 

3 do not just install a single lighting in the kitchen the center, in order to better led kitchen lighting, a multi-level lighting system composed of different lamps and light sources should be installed in the kitchen.

 

4 can be installed in place of the top cabinets low lighting, shadows to reduce work time.

 

5 of the installation site is also very important. Linear incandescent or fluorescent lamps should be installed toward the front part of the cabinet. In this way, part of the led high bay emitted light will be fired after the baffle, and then reflected to the operating table, and then fired at the center of the kitchen.

 

6 if the kitchen space is high enough, you can install a transparent or translucent chandelier on the ceiling as a light source, the chandelier this time can not only provide excellent led kitchen lighting, and decorative items.

RGB led light made by jellyfish?

 

RGB led light made by jellyfish?

 

Have you ever seen a RGB led light made by the corpse of jellyfish? Terrible! This is a crystal style LED lamps, glittering and translucent. The most amazing point of it is that it can automatically emit lights during the night without any help of electricity or batteries. Small LED chips will be plugged into these jellyfishes (after death) in advance. A certain chemical reaction will occur between jellyfish and LED chips to send out a faint light. The color of the light depends on which LED chips used in it. This product enjoyed great popular once been promoted, which exceeded the expectation of most people. Since every jellyfish used is unique (the possibility of copy is zero), each lamp has a relatively higher price, which right now can only be afforded by rich people. “However, the decrease of the cost should be put in the agenda”, said one of the designers.

 

Jellyfish contains a special protein. At the daytime, a certain chemical reaction or you may call it biological reaction will take place between its body and the LED chips. In fact, Jellyfish itself can emit faint blue light in the dark place. After combining it with LED chips, a RGB led light is realized. At present, designers are applying themselves to develop a jellyfish style RGB led high bay. They are confident that their plan will work.

 

In addition, designers fully considered the availability of this LED lights. The transparent resin they used is strong enough to survive after a level 6 earthquake, not mention the accidental falling to the ground.

“Yao Ming brand” home led light

 

“Yao Ming brand” home led light

 

When it comes to home led light, people in the industry know that it originated in 6000 BC Guth, with the ancient Roman Empire to conquer the European continent, the French began to brew and eventually found the soil of their culture to flourish in this land, generated so dumping of the world the unique wine culture the flange Sid some romantic tenderness and wine rich and the perfect combination.

 

Into the Central Plains from the Western Han Dynasty in China, in home led light-related to be talked about than the Tang Dynasty, Han-Liangzhou word “:” grape wine Remanbar want to drink lute reminder immediately. Zuiwo battlefield Jun Mo laugh, ancient expedition a few people back. ” In view of this long history is a major feature of this wonderful liquid. Yao Ming look back, let us focus this figure: born in 1980, into the NBA in 2002, retired in 2011, and Yao Ming entered the business as a commodity brand, it is with your fingers can be calculated. Visible in the historical background, the two are far apart.

 

More importantly, its nobility is not strong. Due to the beginning of the wine production, the production of small, very rare, and has a blood-like color, so often used as ritual supplies for the royal families of exclusive, Jesus is at the Last Supper, said: “I am the bread is meat, led high bay is my blood “, so the red color of the precious beverage with a strong religious and political symbolism.

Judging from the historical context, the wine culture also contains the development, growth in the history and culture of the European aristocracy.

How to measure the power factor of household led light bulbs?

 

How to measure the power factor of household led light bulbs?

 

The power factor is very important factor, because the high power factor can reduce the loss of the distribution network. Reduce the use of electricity to the environmental impact of the most effective way to reduce waste, and regulatory agencies around the world are further strict power factor specification. One example is the Energy Star solid-state household led light bulbs lighting energy efficiency specifications (09/12/07), which provides residential lighting products, power factor (PF) should be greater than 0.7, commercial lighting products, power factor (PF) should be greater than 0.9.

 

LED light bulbs and lighting manufacturers are to respond to these demands, they want their products with the highest possible versatility. Therefore, they are very compatible with a variety of dimmers LED driver circuit, high efficiency and power factor of 0.9 or above. Household led light bulbs by the III – IV compounds such as GaAs (gallium arsenide), GaP (gallium phosphide) semiconductor GaAsP (GaAsP), made ​​the core of the PN junction. It has IN general PN junction characteristics, the forward pass, reverse cut-off, breakdown characteristics. In addition, under certain conditions, it also has optical properties. Forward voltage, the electron from the N region into the P region, and holes from the P region into the N region. Go to the other region of minority carriers (minority) part with the majority carrier (multiple) composite and shine.Known as the led high bay source for the longevity lights. For the cold light of the solid epoxy resin, light body and no loose parts, there is no filament light easy to burn, heat deposition, the light fades and other shortcomings in the proper current and voltage, the service life of up to 60000-10 million hours, more than 10 times longer life than traditional light sources.

The improvement of dimming controller of dimmable led downlight

 

Lighting controller to the line dimming or secondary side of the dimming way to work. The simple line dimming the forefront of SCR controller. This is the most commonly used lighting control, but unfortunately, the use of SCR controller when the dimming of the dimmable led downlight produce a large number of problems. Flexible programmable control functions can be controlled step-down pressure limiting magnitude, the light switch time arbitrarily set. Control mode and sometimes control, light control, manual control, PC remote control and location according to latitude and longitude of automatic control. Soft start, soft transition, the soft-off function to prevent the impact of voltage and cold start current of the lamps, significantly reducing the damage rate of the lamps. Preheat start time, dimmable led downlight, mercury lamps with adjustable lighting can be more fully warm-up, a smooth transition to the normal working condition.

 

To achieve control of the whole dimmable led downlight, and there late at night and then step-down to adjust the flow function, the energy saving effect is more ideal. The perfect re-start function when the load fault, the end of the external power supply failure, automatically re-lit lamps. Control mode and sometimes control, light control, manual control, PC remote control previously used on led high bay and automatic control according to the latitude and longitude of the place of use (optional). Three-phase light switch time and the output voltage can be adjusted independently, which can be accessed imbalances and different types of load. Programmable mode of maintenance, ease of maintenance of lighting systems, maintenance and lamp replacement. Reserved for the normally open contacts of a group of control by the clock in order to achieve a special control. Contact capacity 7A/250VAC.

Several dealers said that the profits are not high sales of LED energy saving lamps, generally only about 10 percent of the family of 8-watt LED lights only ex-factory price of 35 yuan. So, what factors led to the high price of dimmable led downlight In this regard, specially came to the professional production of LED energy saving lights Electric Co., Ltd. of Hebei Long right to visits.

 

In a 600 square meters of production workshop, Liu and more than 50 other workers sitting in the parts of the conveyor belts, hands skilled assembly proceed orderly. Liu introduced a small energy-saving lamps looked at the structure is very simple, but it must be more than 20 process, if a process is not rigorous, it may cause the lamp is not lit.

 

Liu’s work is a cob, green beans the size of the lamp beads into the predetermined mold, the mold needs a total of 37 lamp beads is an essential part of about a 2-watt dimmable led downlight. Liu will be inserted to the good parts into conveyor belt, and quickly picked up by the next person, exposed to the metal line cutting, welding, and then sent to plug the power supply board at the conveyor belt, after which they tested , welding leads, the combination of detection, aging test, a road process, a small LED energy-saving lamps can produce.

 

Lines more than 50 workers a day can produce more than 10,000 led high bay. However, although the yield big profits are not high.

 

Wu Zhanbing come up with a 20 watt LED energy-saving lamps, the only light a total of 330 lights bead composition.

Ip65 led downlight: modification of power factor

The LEDs (LightEmittingDiode) light-emitting diode, is a solid state semiconductor devices, which can be converted directly into electricity for light. The heart of the ip65 led downlight is a semiconductor chip, the chip attached to one end on a bracket, one end is negative, the other end to connect the positive power supply so that the whole chip to be epoxy encapsulated. The semiconductor chip consists of two parts, the part of the P-type semiconductor, the dominant hole in it, the other end of the N-type semiconductor, here is mainly electronic. But the two semiconductor connected when they form a PN junction. “When the current through the wire to the chip, the electrons would be pushed to the P region in the P region electron-hole recombination the form of photons, then it will emit energy, which is the principle of LED light. The wavelength of light determines the color of the light is determined by the formation of the PN junction materials. The technology has matured, one of the signs is ip65 led downlight lighting standards and norms have been put forward. Stringent efficiency requirements already exist for quite some time, and will continue to improve.

Ip65 led downlight: modification of power factor

LED brightness is necessarily related to the led high bay light-emitting angle, the smaller the point of view of the LED the higher the brightness, no super-bright ultra-bright, that is to lie to children, if it is good quality LED regardless of which the brightness of the LED manufacturers are similar, just not the same production process, service life is slightly different, because we are using it a few LED chip abroad.

LED street light market feels sick

 

LED street light market feels sick

 

Led street light market eats too much “Victoria C”.

Throughout mainland China’s led street light market development of the cause, how to see how like a farce, all followed a policy based on hearsay evidence, that was really a bit! But some people are this way, this is not just to take this opportunity to hype a cargo you serve out is not the point, focusing on increasing the corporate visibility, the industry look forward to the prospect of the stock to follow up a penny the heart does not exercise, to make to a lot of money, this time the goods you serve out very clearly not so important.

 

Led street light market doesn’t equal to “Dad”

At least three years ago, the industry as a whole aware of the led high bay in such a state is starting to not market, however, three years time as fleeting, the product as product, price also fell, sales or as sales, of course, the results also or that kind of performance. But this is not a matter of concern not, but listed. Use of government support for this industry can smoothly fishing GEM Listing.

 

Consumer market in the end what

The development of products of the industry is a vital cornerstone of the intention to do the product will always be people out in the confusion of the night you can see a glimmer of hope. And this heart at least to reflect on the concept of humanity. The approach is certainly more than difficult, blowing but also blowing, what to say mouth-blown balloon cannot get blown, but the greater the closer the brink of destruction.
