In-depth segmentation of LED smart home brands

In addition to traditional lighting companies and smart lighting companies, smart home brands also frequently appear in the smart lighting field, such as Oribo, Lumi, and so on. The reason why smart home brands continue to penetrate the field of smart lighting is not without reason.

In-depth segmentation of LED smart home brands

First, smart lighting is an important part of smart homes, and smart home brands can’t miss it. Nowadays, consumers’ acceptance of smart homes continues to increase, and the development trend of smart homes is improving, smart lighting is an important part of smart homes. Naturally, smart home brands will not give up this field. According to data from the China Smart Home Industry Alliance (CSHIA), smart lighting occupies a large market share in smart homes, reaching 16%, second only to home security. In this context, it is only natural for smart home brands to continue to make efforts in the field of smart lighting.

Second, the smart lighting products launched by smart home brands are easier to interconnect with other products of their own. Previously, with the influx of players from all walks of life into the smart home field, the brands and types of smart home products are also increasing. However, due to the different brands, it is difficult for smart home products of different brands to be interconnected. The home experience is also limited and incomplete.

Nowadays, more and more smart home brands are developing in the direction of whole-house intelligence in order to bring consumers a smarter and more comfortable smart home experience. The smart lighting products launched by the smart home brand are more closely connected with other smart home products of the brand, and it is easier to realize the linkage and interaction of the equipment. The stability and intelligence can be higher, and the user’s smart home experience can also be improved promote.

Third, smart home brands are continuing to improve the matrix of smart lighting products to meet the diverse smart lighting needs of users. Due to differences in user room types and habits, their requirements for smart lighting products are also different. Therefore, smart home brands are constantly improving the matrix of smart lighting products. For example, in the field of smart lighting alone, Oribo has launched a variety of smart lighting products. It is understood that Oribo has launched 8 categories, a total of 150 smart lighting products, and has successfully become the industry’s first in the subdivision track of “smart aimless lights”.

LED colorful lights applied in full-color LED light strips

The so-called LED full-color light strip refers to the assembly of LEDs on a strip-shaped FPC flexible circuit board or PCB hard board, which is named for its product shape like a strip. Both the full-color LED light strip and the magic light strip can control the changes of tricks such as single-light horse racing, running water, window opening, meteor chasing, and chasing. Any color can be displayed, and can be combined into any pattern at will, especially when it is made into a light bar screen.

LED colorful lights applied in full-color LED light strips

Both the full-color LED light strip and the magic color marquee light strip have rich and bright colors, high visibility, and visual appeal. It is widely used in wall corridors, indoor environment decoration, entertainment venues, bar backlights for wine cabinets, ceiling backlights, LED light box light sources, LED luminous signs, aquarium supplies, car decoration, etc. It is a new alternative to traditional neon lights, fluorescent lights, and lamps A generation of lighting sources.

Full-color LED light strips are more and more popular among consumers because of their energy-saving features, many patterns, dazzling changing effects, high brightness, reasonable price, wide application environment, and simple installation. Throughout the industry, everyone’s name or name for the full-color light strip is not uniform. The professional name is that the full-color LED light strip is also called the LED magic light strip.

Compared with the general light strips in the market, this product mainly has an extra driver IC on the FPC board. At the same time, there are certain standards for the copper requirements during the board manufacturing process. If the copper is not used properly during the manufacturing process, will seriously lead to product instability, so the convention is that the board requirements for full-color LED lights with 12V 30 lights will be above 2A copper on double-sided boards. 144 lights generally need to be above 2.5A copper.

LED full-color light strips and LED full-color light strips are generally universal, and both refer to flexible light strips; but magic light strips specifically refer to flexible light strips, that is, the light strips that use FPC as the circuit board. The light bar includes two kinds of soft light bar and hard light bar. One is to use FPC as the circuit board, and the other is to use the hardboard as the circuit board. The general standard of voltage used is DC 12V voltage, and some use 24V voltage. There are also custom-made ones, available for 6V and 9V. The common standard for light strips on the market is to use 12V voltage.

Chengdu completed the transformation of more than 100,000 LED light poles

It is understood that in order to match the various lighting management and maintenance needs in the main urban area of Chengdu, the Chengdu Lighting Internet of Things Big Data Center came into being. The platform can actively and accurately identify street lamp failure types, equipment identification, GIS geographic location, and other information. After receiving the fault information, the platform will classify the algorithm according to the road section, safety hazard, and fault category, dispatch it to the front-line maintenance personnel in the form of a work order, and collect and archive maintenance results to form efficient closed-loop management.

Chengdu completed the transformation of more than 100,000 LED light poles

“Giving ID cards to street lamps is not just as simple as pasting signs,” said the relevant person in charge of the platform. Location and other information give each main light pole a unique identity, and through digital twins, the light poles can truly ‘live’ with us in the streets and alleys of Chengdu.”

Up to now, more than 100,000 light poles have been transformed, more than 100,000 single light controllers have been installed, and more than 800 smart monitoring boxes have been replaced, so that all light poles with certificates can be connected to the “network”.

It is an “ID card” and a “medical insurance card”, and the street lamp can also be “registered” automatically.

After taking out the mobile phone to scan the QR code on the “ID card” of the street lamp, you can enter the “diagnosis” page of the lamp post – Chengdu Street Lamp Repair WeChat applet, which records basic information such as the number of the lamp post and the road where it is located.

“Citizens encounter street lamp failures in their lives, and can locate the faulty light pole by scanning the code. If the QR code cannot be scanned due to contamination or missing, they can also locate and report the fault through the small maintenance program. Compared with the traditional telephone fault reporting and repair applets can help us locate the fault point more accurately and quickly.” said the staff of Chengdu Lighting Internet of Things Big Data Center.

The staff member said that the front-line lighting operation and maintenance personnel are like “doctors” who specialize in the field of urban lighting. Every day they will carry out systematic inspections according to the plan, and the lighting problems they find and solve will also form a part of the city. Lighting “medical records”, according to the characteristics of these diseases, the lighting Internet of Things big data center will continue to optimize the daily inspection plan, forming a closed loop of inspection “diagnosis and treatment”.

The light pole transformation work completed before is also particularly important at this time. A variety of intelligent diagnosis and treatment equipment, including single-light controllers, intelligent monitoring boxes, and water-logging monitoring sensors, have been transformed and constructed to replace manual inspections. The networked big data center alarms, and generates a “registration list” according to the pre-configured alarm algorithm or through manual assignment, and automatically dispatches the front-line personnel to go for maintenance. When the equipment maintenance is completed, the system alarm recovers, forming a closed loop of intelligent perception and fault reporting.

Municipal lighting in Huishan District, Wuxi, Jiangsu

Street lights are dots of “starlight” that light up the night sky of the city, illuminating the road for citizens to travel safely at night.

Municipal lighting in Huishan District, Wuxi, Jiangsu

In recent years, with the development of urban and rural construction in Huishan District and the continuous improvement of the traffic road network, the mileage of urban roads in Huishan District, Wuxi City, Jiangsu Province has increased by leaps and bounds, and the energy consumption of street lamps has increased year by year. According to statistics, Huishan District currently has more than 45,000 municipal lighting street lamps, but more than 35,000 of them are still using high-pressure sodium lamps. There are problems such as unreasonable energy consumption, imprecise management, and low urban lighting level.

Since 2022, in order to systematically improve the status quo of municipal lighting, Huishan District has been based on the long-term, focused on the future, promoted high-quality development with firm reforms, and initiated the implementation of contract energy management for municipal lighting facilities in the district.

What are the aspects of contract energy management for lighting facilities?

1. LED Energy Saving Transformation

It is planned to use 2-3 years to invest 87 million yuan to carry out LED transformation and single-lamp controller installation for 35,000 municipal lighting street lights. “The application proportion and power saving rate are higher than the city’s level.

2. Lighting intelligent supervision

Utilizing mature technologies such as GIS and Sanyao, an intelligent supervision platform for municipal lighting facilities in the whole district is simultaneously established to realize “one-network unified management” of lighting facilities in districts, towns (streets), and villages (communities), and to realize the dynamic grasp of information by district authorities and Intervention management and assessment.

3. Adjust the management system

The lighting facilities after the energy-saving transformation will be fully taken over by the District State Control Group, which will unify the management and maintenance entities at all levels, making the scientific and technological means, personnel technology, mechanical equipment and other aspects highly specialized, and strive to build a professional municipal lighting maintenance team based in Huishan.

Benefits of energy management contracts

It is reported that contract energy management can not only solve a series of software and hardware problems in the municipal lighting industry in our district, but also produce obvious economic benefits. According to preliminary estimates, after the energy-saving transformation is completed, 160 million kilowatts of electricity can be saved in ten years During the ten-year contract period, it is estimated that the government will save 112 million yuan in electricity bills, and the electricity energy-saving benefits generated will be distributed by the district-level finance and the State Control Group in a certain proportion. Public lighting resources such as street light poles will also be deeply tapped by the State Control Group. The potential value is used to feed back the development of the municipal lighting industry in the whole region, and then realize the healthy development of the municipal lighting industry.

Next, the Fangxian Urban Management and Law Enforcement Bureau will go all out to organize the equipment and personnel, accelerate the project construction, and ensure that the lighting project is completed on schedule and with high quality.

Dalian Bay Submarine Tunnel Lighting System Lights Up

Recently, after 120 consecutive days of high-intensity fighting, the lighting system of the first cross-sea immersed tube tunnel in the high-latitude cold region of my country has been completely installed and debugged, and the interior of this submarine “giant dragon” has been fully lit.

Dalian Bay Submarine Tunnel Lighting System Lights Up

As a high-tech submarine lighting system, the artificial intelligence lighting of the Dalian Bay Submarine Tunnel in Dalian City, Liaoning Province can achieve harmony and unity with natural light, and can “feel” cloudy, sunny, cold, and warm, night and day – can adapt to the light perception of the four seasons change, timely adjust the color temperature and color difference between the seabed and the land area; adjust the brightness of the seabed light in time according to different weather such as sunny, cloudy, rainy, snowy, foggy, etc., as well as different light intensities such as morning, evening, daytime, and nighttime “High EQ” two-in-one.

To light up such a huge “dragon” on the seabed, there are many types of lighting that need to be set up – basic lighting in the middle section of the main line of the tunnel/ramp, emergency lighting, enhanced lighting at entrances and exits, lighting for awnings, passage lighting, and lighting in equipment rooms etc.; there are more than 10,000 sets of lighting fixtures alone, and the total length of the laid circuit is nearly 420,000 meters, involving nearly 180,000 meters of power pipelines, and nearly 10,000 sets of hangers…

At the same time, a strong power supply system is also required to support one lighting power distribution room and emergency lighting power supply room are respectively set up in the north bank equipment area of the tunnel, the south bank equipment area (1), and the south bank equipment area (2). Install 2 lighting equipment platforms. The lighting distribution room is equipped with a lighting distribution cabinet, an intelligent lighting control cabinet, and a lighting distribution box in the equipment area. The emergency lighting power supply room is equipped with a centralized emergency power supply device and a type A emergency lighting centralized power supply. A 10kV/ 0.4kV buried transformer for lighting, lighting distribution cabinet, intelligent lighting control cabinet, centralized emergency power supply device, and A-type emergency lighting centralized power supply.

Such a complicated submarine lighting system installation project is faced with difficulties such as time constraints, heavy tasks, and cross-operations. Especially for the lighting installation of the arc section of the submarine tunnel, it is necessary to convert the distance of the center line of the road into the distance of the inner arc and the outer arc before construction. , In addition, the installation of lamps and lanterns is a high-altitude operation, which is more dangerous. The Dalian Bay Submarine Tunnel Electromechanical Team of the China Communications First Harbor Engineering Co., Ltd.’s installation company faced difficulties head-on and took measures such as advanced layout, process coordination, and precise debugging to ensure quality and quality with the construction rhythm of “all-weather operations” such as non-stop holidays and shifts during the day and night. Quantitatively promote the construction progress. In the end, the important project node of lighting installation and commissioning for the entire tunnel was successfully realized.

This submarine “dragon” was successfully lit up, marking another crucial step towards the goal of opening the Dalian Bay Submarine Tunnel on time.
