LED urban lighting street price is difficult to promote the popularity of high

LED device products applied to the lamp, special requirements on technology mainly is to combine LED light intensity and light angle to design, also due to multiple combinations of LED optical design to take into account the irradiation area, lighting needs to focus on the effectiveness of radiation.

Although China has LED city street lighting development and production enterprises, but many small power LED array as the luminous body, solve the problem of radiation, the quantities of LED to a lot of small power LED light, high installation cost.

LED urban lighting street price is difficult to promote the popularity of high

City Lighting LED lamp with high power LED is the trend of development, with few high-power LED street light emitting body because there is no good solution to power reaches a certain amount, the heat of LED, astigmatism and spotlight LED control problem, equilibrium problems in pavement surface illumination lamp irradiation range, type and intensity of illumination the problem, the photoelectric conversion efficiency is too low, the product performance is still not satisfactory.

High performance products and high prices, it is difficult to promote universal. Heat dissipation and reliability are the main factors affecting LED applications. LED device products applied to the lamp, special requirements on technology mainly is to combine LED light intensity and light angle to design, also due to multiple combinations of LED optical design to take into account the irradiation area, lighting needs to focus on the effectiveness of radiation.

LED street lamp and ordinary street lamp comparison, has the following advantages: energy saving, environmental protection, low pressure and easy adaptation, and can also be directly supporting the solar system, without additional inverter, the conversion process, can achieve the maximum energy utilization rate. The use of LED street lamp also has some deficiencies, such as the lighting angle is small, uneven, color rendering index is low, optical, thermal design complex. In addition, the current technology is not enough luminous flux, light efficiency is too low, quality is difficult to guarantee. Therefore, LED products used in street lamps need special design, but also the need for specialized standards (using the traditional light source test data to evaluate the LED light source is often not objective).
