LED street lamp light distribution present situation how?

In the current market conditions, the status of LED lights? Currently in use of the shortcomings of LED street light distribution methods? Let's take a look at the LED street lamp power distribution related description. 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 lights maintenance costs low, compared with the traditional street light, LED street lights maintenance cost is extremely low, through the comparison, can recover all input costs less than 6 years. LED street light automatic control and energy saving device, can realize to meet the requirements of different times lighting cases, most likely to reduce the power, saves the electricity. Can realize the computer dimming, period and control, light control, temperature control, humanized functions such as automatic inspection. Under the current market there are two kinds of LED street light with the light distribution form, the first is the traditional road lamps shell, just inside the lamps and lanterns, installed in a is almost flat surface ( Is also a reflective surface) On a matrix of LED, the second method is to concentrate multiple leds in a circular area ( Area 30 ~ 40 mm diameter) , make this a small area of the light output density close to the high intensity discharge lamps, lamps and lanterns of recycling reflector for light distribution. Among them, the first method to design this kind of LED street light with the light quality is not very good, and the second method and the heat dissipation is not good problem exists, then LED to reduce the LED street lamp luminous efficiency and reduce the problem of service life. LED street light road lamps and lanterns to truly meet CJJ452006, CIE31 CIE115 standard illumination and intensity of illumination uniformity requirements, lamps and lanterns should contain three light distribution function can be better implementation. But with reflector with reasonable output light beam Angle of the LED itself has good light distribution function at a time. Within the lamps and lanterns, can according to the height of the street lights and road width design LED street lamp installation position and the direction of the light is emitted, can achieve good secondary light distribution function. In this kind of lamps and lanterns of the reflector, only as a auxiliary means of three light distribution, to ensure better road illumination evenness. Above is the present situation of LED street lamp light distribution related introduction, if you have questions, you are welcome to inquire, we continue to update more related content for you, you can pay attention to our website to learn more.
