Outdoor lighting in China represents about 30% of lighting consumption, production and life are closely related with people. LED street lamp outdoor lighting as an important application, its advantages:
1, long life high power LED street lamp
We are very concerned about this issue the focus, as many foreign experts and the company's products described Brochure 5-10 million hours, and optimistic, in fact, high-power LED street lamp life depends on the following points:
(1) LED light source chip quality, light attenuation.
(2) LED package quality. Consistency and reliability.
(3) LED light source as a cold, but the LED semiconductor itself will generate heat. LED cooling, to ensure good working conditions for LED.
(4) power supply, constant current driver's lifetime warranty.
2, energy efficiency
Lighting is a systems engineering project, whether it is clear, as the lighting or mood lighting is by electricity into light, and then through the projection lamp to be a local face to face to achieve a certain degree of illumination, uniformity, color rendering, more than being face to face Local synthesis of a complete lighting project, not simply to compare with the power, but through an integrated, comprehensive analysis of the comparison.
3, conventional semiconductor LED lighting lamps and differentiation
Light is light, power, shade, and other accessories such as a combination of lighting equipment assembly, it is also used to control the light source, light projection means, the same time protect the light source lighting to improve lighting efficiency tool.
Mainly by conventional street lighting lamp housing, light source cavity, electrical rooms and other components. Because there is enough space and the carbon shell and foam silicone rubber seal to install heat, ensuring the working conditions of light. The light source cavity protection grade IP65, electrical protection class room IP45. Conventional street lighting to ensure this protection as long as the conditions can be molded into any shape, China's conventional road lighting design brilliant, really show the viewing day, night Guandeng scene.
The advent of the semiconductor LED lights, its unique long-life light source, with reasonably easily with the advantages of light, color temperature variability, the advantages of high color rendering index, low-voltage current source power supply with the development of energy efficient trend.
The LED lamps have natural advantages apply to their advantage:
1.LED as a point source, if designed, can solve a large extent, the traditional spherical light source to rely on to solve the second optical transmitter and optical loss of light to take the issue;
2. Light irradiation surface uniformity control, in theory, can be completely uniform in the target area, which can avoid the light "lamp light" phenomenon of light waste;
3. Color temperature optional, so that applications on different occasions, but also improve efficiency, an important way to reduce costs;
4. Technology is still much room for improvement.
4.LED lights with light optical reasonable
LED and traditional lighting different, it has a point light source, high brightness, narrow-beam output and so on. LED lights do first to consider the use of the full flux limited exposure to the effective scope of the requirements is the road street lighting, road space is not beyond the effective range of street lighting. Therefore, the effective control of light distribution, so that LED light emitted as a long strip of light along the surface with the direction of spreading, while taking care of glare generation, is the LED lighting designers made the new and higher requirements.
