Although under the background of the development of the market, LED street lamp is gradually to each person's field of vision, but the development of LED street light there are still some problems.
Manufacturer of LED lights ED street lamp light is higher than high pressure sodium lamp many color, high pressure sodium lamp only around 23, color rendering index and the LED street light color rendering index above 75, think in terms of visual psychology, to achieve the same brightness, LED street light can, on average, more than 20% lower than the high-pressure sodium lamp.
LED street light along with the rapid growth of the national economy, the contradiction between supply and demand of energy in our country, start there is a serious shortage of electricity supply situation, saving energy that is an urgent need to solve the problem.
Therefore, the development of new type of high efficiency, energy saving, long life, high color rendering index, environmental protection of the LED street lamp for city lighting energy saving is of great significance.
What your problem is?
What are the problems of LED street lights also?
Street light of one of the problems: light distribution problem, currently in use is the most common form of LED street lamp in LED lamps and lanterns is installed in the matrix, in almost flat installation, lamps and lanterns of this design method can't get good light distribution effect.
Power LED is almost always equipped with reflector (
Than the reflector reflector efficiency significantly more efficient.
LED street lamp still exist question # 2: heat dissipation problem.
The road lamps and lanterns is aluminum shell, direct use of lamps and lanterns outside shell as a radiator, can meet the requirements of IP protection grade, also can get a lot of heat dissipation area.
In addition, the shell of lamps and lanterns of the radiator in dust fall, can wash by natural wind and rain, to ensure the continued effectiveness of the radiator.
Finally, the LED street lamp driver power supply problems still exist.
The requirements of the LED driver circuit is to ensure that the characteristics of constant current output.
Due to the relative changes of voltage LED forward work area is small, the LED constant current drive basically ensures the constant power output of the LED.
