Do you know the past and the future of LED street lights ?

LED street light currently exist in the United States, Europe and China.Among them, the characteristics of Chinese LED street light are characterized by modular structure, high protective properties of modules, and high protective water-resistant joint modules and actuators.And the European LED street lamp features a full-plate version, a shiny glass with steel, and little or no heat sink on the back.The characteristics of American LED street lamps are in the form of the majority and the compass.
Due to have respiratory effects in the outdoor LED street light, breathing effect cause gas exchange occurs in the wall, make the external toxic or harmful gases into the lamp cavity corrosion unprotected lamp bead and aluminum plate, causing death lamp.In order to solve this problem, there are many innovative designs in China.For example, the application of rubber and water on PCB boards is used to solve the corrosion failure of the bulb and PCB.
Modularization scheme is Chinese innovation, as early as the beginning of 2009 , the first to put forward the concept of modular LED street light, through the standardization of the LED module can solve the heat dissipation, waterproof, light distribution, maintainability, versatility, and many other problems in the field of high power LED lighting.The future of the LED industry requires a new business model to address industry pain points. LED street light the more intensive, the lower the cost;The higher the intensification, the more advanced the technology.

At this stage, the overall lamp market competition is more and more fierce, the product price declines continuously increased, but the cost of power supply in the proportion of the whole lamp cost has been high, resulting in profit space gradually compressed.The cost of the whole lamp is 39 percent, the cost of the lamp is 26 percent, the cost of the kit is 29 percent, and the cost of the accessories is 6 percent.
100 w LED street light, for example, the whole lamp price from $1.10/W in 2014  fell to 0.70 in 2016 $/ W, drop to 34%, but the price of the power supply remains at $19.85 in 2016, only 28% decline.
In the high-end power cost, from the cost of raw materials is as high as 60%, when prices unchanged, an integrated circuit can accommodate the number of components every 18 to 24 months will be doubled, the performance will be doubled.
In terms of managing costs, the future industry tends to be more concentrated and the market is more affordable and efficient.In terms of the cost of selling, the market concentration and the brand effect are continuously promoted.In terms of the cost of workers, the scale of the future of a single LED street light product has led to automation of production.All of these can effectively control and reduce costs.

What ways can see LED street lights to replace the high pressure sodium lamp?

Image
Under the condition of current technology,luminous efficiency of  LED street lamp  is more than high pressure sodium lamp, it is an indisputable fact that TEK LED street lamp can reach 160 LM/W. And HPS spectrum is concentrated in the yellow area, its color temperature is low, only 2000-2500 k, and relatively high color temperature such as LED, LED street light natural white temperature of 4000-5000 k, cold white is 5000-6500 k. At the same time compared with HPS, LED street lamp with high color rendering index, close to natural light in the actual lighting, can bring a person the sense of comfort. Followed by "irradiation uniformity", although the  LED street lamp  lighting is relatively concentrated, but can be by the light path of the second design, can make the light source of lamps and lanterns presents the ideal state, realize the reasonable light distribution curve adjustment, control the distribution of light, so a...

The advantage of new style TEK LED panel light is obvious

Image
TEK  LED panel light , continue to use the reflective surface luminous technology, light after secondary reflection through high light transmittance mask projection, reduce glare, the light is more soft and comfortable to the human eye to watch not easy fatigue, particularly for students who have long time exposure to indoor lighting lighting, subway passengers or office staff. The application of the patented reflective material ensures the reflection efficiency of the light, and the original high light effect of the panel light is retained to the maximum extent. In order to guarantee the reliability of the use,   the design principle of TEK LED panel light  adhering to the "maintenance", improve heat dissipation performance, reduce the LED light failure of lights and lanterns, significantly prolong the service life of the lights and lanterns, saving the maintenance cost of lights and lanterns. TEK LED panel light is more intelligent TEK LED panel light c...

Safe travel: TEK LED high bay light illuminate the locomotive base

Image
In recent years, China's rail transportation has been developing rapidly, and many second and third-tier cities have made great efforts to build urban subway projects, which have brought convenience to people.Subway passenger traffic is large, the operation security is always the top priority, the metro management department attaches great importance to the security of the train, and TEK LED high bay light  illuminate the locomotive base, which facilitates the maintenance and maintenance of subway vehicles. Traditional lighting there exists large droop, short service life, the problem such as glare, can't use how long will be replaced, is not only the economy, and the human eye in this light, easy to produce fatigue, especially the night repair subway locomotive, a bit not careful see not clear parts fault, cause hidden trouble.Today, many subway lines use LED high bay lights , which make lighting more efficient and more efficient.Second, can improve work efficiency, the ligh...
