Our entire lighting outdoor lighting accounts for about 30% of electricity consumption, and it is very closely related with people’s life. LED street lighting as important outdoor applications, its advantages:
1, high-power, long life LED Street light
For this we are very concerned about the focus of the problem, as many domestic and foreign experts and the company’s products as described in publicity pictures 5-10 million hours and optimistic attitude, in fact, high-power LED street life depends on the following points:
(1) LED chip quality light source, light attenuation values.
(2) LED packaging quality consistency and reliability.
(3) LED light source as a cold, but the LED semiconductor itself will generate heat. LED heat is to ensure good working conditions for the LED.
(4) Power supply, constant current drive lifetime warranty.
2, energy efficiency
Lighting project is a systematic project, whether it is photonic lighting or mood lighting, all is through electrical energy transferred into light, and then through the projection lamp, so that one is face to face up to a certain partial illumination, uniformity, color, multiple being face to face Local synthesis of a complete lighting projects, not simply to compare with the power, but through an integrated and comprehensive analysis for comparison.
3, the differentiation between normal lamp and conventional semiconductor LED lighting lamp
A light source lamp, power supply, and other accessories such as shade assemble combination of lighting, it is also used for controlling the light source, light rays manner while protect the light source, and improve the lighting efficiency of the lighting equipment.
Conventional street lighting mainly consists of the lamp housing, light chamber, electrical room and other components. Because there are sufficient housing space and the carbon and foam silicone rubber seal mounting cooling, to ensure the working conditions of the light source. The light source cavity protection is IP65; protection class electrical compartment is IP45. Conventional Street lighting only conform with this protection conditions, it can be made into any shape, our conventional road lighting design are brilliant, it really shows daytime viewing, night lanterns scene.
While the born of the semiconductor LED street light, their unique long-life light source, with easy superiority of rational light, color temperature variability, the advantages of high color rendering index, low voltage and current power supply processed with energy efficient lighting trends .
LED Street light has inherent advantages when it used for streets, its advantage lies in:
1.LED as light source, if designed properly, so it can largely be addressed directly to rely on traditional spherical light emission source to solve quadratic light extraction and optical loss issues;
2. Uniformity of the light irradiation surface controllable, in theory, it can be completely uniform within the target area, which can also avoid the light “lamp light” phenomenon of light waste;
3. Selectable of color temperature, so in different occasions applications, it also a important way to improve efficiency and reduce costs;
4. Technical progress still has great room to improve.
5. LED Street light with light optical rationality
LED is different from conventional lighting; it has a point light source, high brightness, and narrow beam output characteristics. To do LED street light, you should first consider the limited flux to the effective use of the full range of illumination, The street required for road lighting effects, beyond the road space than the effective range of street lighting. Therefore, the effective control of light distribution, so that the light emitted by the light emitting tube into a long strip of tape along the surface direction of light spread, while taking care of generation of glare, which is a new type of LED lighting design professionals and higher requirements.
