How to solve the LED street lamps, several still issues, in an in-depth understanding of the market demand based on further application become common concern for all parties.
Do you think that in 2011 LED the dimensions of the street lamps have how unused?
Preliminary estimates, 2011 LED the market capacity street lamps in 50 ~ 8 billion.
At present, the LED street lamp to further application of the market the existing problem is going to be???????
From a technical perspective has no too many questions, for general corporations major difficulties in chip encapsulation technology route choice and judgment, which, of course, also won't have too big effect. Power drive, with light, heat dissipation, now the technology has matured, these problems you may get a good solution. In fact, the power supply life do 2 ~ 30000 hours is no problem, better can do 50000 hours, if the source of the life can do 100000 hours, with okay driving power supply additionally be a change of 5 years, stood in anyone's perspective is also sufficient.
Mounting at present will not not have uniform standard, have a plenty of single package, have a plenty of integrated packaging, single encapsulation relatively simple, integrated packaging relatively complex, cost is high, with light and reliability hold problems. The phenomenon of your zebra grain main or light distribution problem, subject to light source and features of the light distribution should be perfected.
At present, the LED street lamp of the average efficacy level reached 75 ~ 95 lm/W, development and reform commission requirement is 85 lm/W, incorporates a very high, with foreign chip can also doing it. The traditional sodium lamp light efficiency is 50 ~ 60 lm/W, must do less than 90 lm/W such efficiency, from this point, LED the street lamp energy advantage has prominent.
To be successful application of business is to turn into a key right the lamp of performance to price ratio, namely the economy ShiYongXing lamp, represent the mainstream market demand.
Intensity of illumination and brightness within the evaluation standard has some dispute, a person you see?
About the concentration of illumination and brightness of the evaluation standard, some experts suggest more always be the brightness and the intensity of illumination of the evaluation standard, it is perfectly stood in the educational point of view, the pursuit a good ideal state, nevertheless the truth is, a lot more than general enterprise is no easy task to have the physical conditions of the measurement brightness, even might be of the street lamp management office is also in order to have such a complaint that. The future in this respect may realize breakthrough, but with brightness do it may not be realistic standard, still would like to related testing equipment and testing means supporting.
