Problem of energy-saving LED street light in our country and its development trend prospected

Image
At present, the lighting electricity consumption accounts for about 13% of the total electricity consumption, the road lighting accounts for 25% ~ 30% of the entire lighting electricity consumption, thus the road lighting has great energy saving potential and space. In recent years, the development of energy-saving  LED street light  and demonstration project has made great achievement in our country, one of the leading enterprises in the international.But there are also many bad places and exposed some problems, needs to be improved.The problems mainly include: 1, grasp the quality of white LED light source is lax, improper use.Including the flux of the light source, light failure, light color and life quality, thermal management, large quantities of products, such as the reliability and consistency of performance indicators is relaxed, and the domestic high power LED light blue chip failure is serious, thus causing some  LED street lamp  lighting engineering the re...

The contrast of traditional street lamps and LED street light

Image
LED street lamp  is a semiconductor diode, its life is very long.When the flux decay to 80%, its life up to 50000 hours.And the life of the metal halide lamp only 6000 ~ 12000 hours, high pressure sodium lamp life is 12000 hours.    LED street light, the basic structure is an electroluminescent semiconductor materials, placed on a wire rack, then sealed with epoxy resin around, protect the internal core, so the LED street lamp of seismic performance is good.   Light color of white  LED street lamp  is better than high pressure sodium lamp.In the middle level of the visual, the human eye in high color temperature environment than low color temperature environment are easy to identify things.Color rendering of white LED is much better than high pressure sodium lamp, high-pressure sodium lamp color rendering index only 20 , white LED street light more than 80.   LED street lamp can realize dimming function more perfect.As a result of t...

What about the quality of most popular UFO LED high bay light ?

Image
whether the most popular  UFO LED high bay light  quality is good? really energy-saving, save electricity, compared to the traditional lamp, what about its service life ? So does the appearance of UFO LED high bay light is good for heat dissipation? UFO LED high bay light can be said to be one of the most popular in 2017 a industrial lamps and lanterns, especially the foreign customers, especially like, a lot of factory integrating industry abroad in 2016 sales a lot, because the  UFO LED high bay light  not only extend the characteristics of ordinary miner's lamp, suitable for power in the 100-240 w high power led high bay lights. Due to the nature of the UFO LED high bay light is small volume, exquisite appearance, IP65 protection grade, suitable for lighting factory, warehouse lighting at the same time, compared to the traditional led  is suitable for exhibition hall lighting, commercial super lighting, exhibition hall ligh...

Industry observation: LED street lamp product manufacturing cost analysis

At present, our country urbanization construction continues to advance, the state vigorously advocated development "energy saving, low carbon” economy , high efficiency and energy saving LED light source is widely used, many cities using the primary and secondary trunk road of high efficiency and energy saving of  LED street light , it is desirable for the LED lighting industry, but also on the market there is inferior product to disrupt the market at a lower price, so, what is a LED street lamp product manufacturing costs?   LED belongs to technology-intensive industry, product quality, with the technology and craft level is closely related to remember "You get what you pay off ", in the outdoor LED street lamp market, there are a lot of products with a less known and inferior brand, don't be confused in the inferior products of low slogan, to do an in-depth analysis, deduce its manufacturing cost, thus to assess the quality of product.   In general, a com...

How to development LED corn light ?

Image
In recent years, China's social economy is undergoing profound changes, into the "new normal" economic growth way, under the background of reform, China's manufacturing industry is accelerating close down backward production facilities, develop high-tech industries,  LED corn light  as "advanced" in the field of industrial lamp, everything from the chip, encapsulation, application, etc in the industrial development to follow up with lamp market, LED corn light industry entered a new stage of development.   The current domestic many vendors on focus on developing LED corn light, unlike previous "blind expansion", this time is more rational and more intimate relations between enterprises.Completes the  LED corn light , need the whole industry chain cooperation together, innovation, coordination, the development of green, open, sharing concept has been widely accepted by the industry.   LED corn lamp is innovative products and green environmental prot...

Intelligent dimming system help LED street lamp market rapid development

Image
At present, many cities in our country roads are using LED lighting, LED light source with high photosynthetic efficiency, low power consumption, long life, good stability, high reliability etc, the  LED street lamp  brought people a bright light, the road could see them more clearly, the LED light source in the road lighting application proportion rises year by year, while intelligent dimming system accelerated this process.   In the current domestic road lighting, still give priority with the traditional high pressure sodium lamp, the lamp light failure is big, a year or so will drop to 30%, lighting quality is not very stable, and color rendering index in 25 or so commonly, and most of  LED street lights  above 70. At present, many developed countries in promoting the lighting upgrade project, will replace traditional street lamp into LED lighting, not only is the LED light source can be high efficiency and energy saving lighting...

LED street light market permeability increase

Image
In the current our country economic growth stability, LED market investment recovery, related industry in the recovery, under the background of reform of supply, low-end manufacturing is phased out excess capacity, and promote the development of science and technology, environmental protection industry, street lights market change is an example , high efficiency and energy saving of  LED street lamp  market, penetration has risen steadily. Traditional road lighting is given priority with high pressure sodium or halogen lamp, the market share of LED street light is less than 30%, on the one hand, subject to economic growth, the decline in investment in fixed assets, LED enterprises in excess capacity of market environment, for the development of  LED street lamp  become cautious;On the other hand, Society for knowledge of the road lighting of LED light source is not very full, replace the lamp will not very strong. The LED street l...
