One, one-way light

LED light pole itself features --- light one-way, no light diffusion, to ensure the efficiency of light.

Second, high luminous efficiency

LED lights have a unique secondary optical design, the LED lights light irradiation to the required lighting area, to further improve the efficiency of light. Has reached the purpose of energy conservation. At present, LED light source efficiency has reached 100lm / w, but also a lot of room for development, the theoretical value of 200lm / w. The high-pressure sodium lamp luminous efficiency is increased with the power increased, therefore, the overall effect of light LED lights than high pressure sodium lamp.

Third, the light color is high

LED light color than the high pressure sodium lamp much higher than the high pressure sodium lamp color rendering index is only about 23, and LED street light color rendering index of 70 or more, from the visual psychological point of view, to achieve the same brightness, LED lights can be more than the average light The sodium lamp has been lowered (see the British road lighting standard.)

Fourth, the light is smaller

LED lights light decline, a year of light failure less than 3%, the use of the road is still used to meet the lighting requirements, and high pressure sodium lamp decline, about a year has fallen more than 30%, so LED lights in the use of power design Can be lower than the high pressure sodium lamp.

Fifth, energy saving

LED lights have automatic control of energy-saving devices, to meet the lighting requirements in different periods of time to meet the maximum possible reduction in power, saving energy.

Use relatively safe. LED is a low-voltage device, driven by a single LED voltage for the safety voltage, the series of single power are 1 watt, so it is a more secure than the use of high-voltage power supply, especially suitable for public places (such as: street lighting, Mine lighting, automotive lighting, civil lighting, etc.).

Six, easy to maintain

Each unit LED chip is only a small volume, it can be prepared into a variety of shapes of the device, and suitable for a variable environment.

Comprehensive the above principles, high-power LED lights energy-saving effect is remarkable, instead of high-pressure sodium lamp can save 60%. Although high-power LED lights have many advantages, but it is difficult to large-scale replacement of high pressure sodium lamp. The reason is that the quality of LED lights is not stable enough, the cost is too high due. Nevertheless, LED lights have energy-saving, long theoretical life, the advantages of environmental protection lights, in the world to promote green today is very bright, the government and the industry's attention and strong support.
