LED street lights and the difference between ordinary street lamp LED light source adopts low voltage dc power supply, by GaN blue LED power and yellow synthetic efficiency white light, quiet is high, energy saving, environmental protection, long service life, the corresponding rate of fast, high color index, etc. The path can be widely applied to the gate. 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. 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. Cover can be made, resistance to high temperature can reach 135 degrees, resistant to low temperature can reach 45 degrees. Advantage 1, the characteristics of LED street lights - The light unipolarity, light diffusing, surrounded by the light to obey. 2. LED street lamp has a unique secondary optical floor plan. It needs light lit LED lights area. In order to achieve the goal of energy saving, further enhances the obedience of light. 3, LED 111130 lm/W, there is a larger living space, the theoretical value of 361 lm/W. High pressure sodium lamp luminous obey quantity increases with the power. Therefore, the LED street light in terms of overall photosynthetic efficiency than the high-pressure sodium lamp is strong; ( The integral luminous efficiency of the LED street lamp is theoretical, in fact, more than 250 w high pressure sodium lamp is more effective than LED lights) 。 LED street light color is far higher than that of high pressure sodium lamp. Color rendering index of high-pressure sodium lamp is only about 23, and LED street light color rendering index of 75 or higher. From the perspective of visual physiology, the brightness of the LED street lamp can be evenly. It is 20% lower than the high-pressure sodium lamp. 5. Light attenuation is very small, less than 3% a year. Ten years later still can meet the requirements of the road, and high pressure sodium lamp within a year or so has fallen by more than 30%. Therefore, the LED street light than high pressure sodium lamp industry low rate in the plan. 6. LED street lamp is equipped with active control and energy saving device, satisfied with different periods of lighting environment and maximum approximation of low power consumption and throttling energy. It can realize the computer dimming, cycle time control, light control, temperature control and active detection of human nature. 7, long service life: can use more than 50000 hours, provide three years warranty. The disadvantage is that the life of the power supply can't guarantee. 8. High light efficiency: to accept more than 100 lm chips, compared with the traditional high pressure sodium lamp, energy saving more than 75%. The placement of light: don't need to add embedded wire, without a rectifier, etc. , will be placed directly on the light pole light pole may be embedded in the original lamp shell. 10, excellent heat dissipation control: control the temperature of a hot day in 45 degrees, with the method of passive cooling, heat dissipation of heat protection is not enough. 11. Reliable quality: power supply circuit adopts high quality components, each LED have separate over-current protection cover, need not worry about the damage. 12, uniform light color: no lens, no gradual brightness and uniform light color, to ensure uniform color without aperture. 13, LED does not contain harmful metallic mercury, discarded when won't cause harm to the environment. Comprehensive the above principle, the energy saving effect is obvious. Replace the high-pressure sodium lamp can save electricity above 60%. Low maintenance cost: compared with the traditional street light, LED street lights maintenance cost is low, the last to recover all the investment cost is less than 6 years.
