With the continuous consumption of energy and resource shortage, the greenhouse effect has become increasingly significant harm to human beings, the atmospheric environment on the earth's pollution is more and more serious, international calls for saving energy and reducing consumption of more and more high, the energy conservation became the various countries' work in the weight of the
with the continuous consumption of energy and resources are increasingly scarce, the greenhouse effect is more and more big, the harm to human beings, atmospheric environment on the earth's pollution is more and more serious, the world is more and more high to the requirement of saving energy and reducing consumption, energy conservation has become a national priority.
As early as 1996, China formally launched the green lighting project, lighting engineering should save resources, prevent pollution, the benefit of future generations.
Over the years, through the joint efforts from all walks of life, as the fourth generation light source semiconductor (
领导)
Lighting products, energy conservation has made remarkable development and remarkable achievement.
The outdoor road lighting accounts for about 30% of the total energy consumption of lighting, is closely related to people's production and life.
As an important application of outdoor lighting, led street light has the following advantages: 1.
Power leds lamps long life for the focus of the problem, as many experts at home and abroad and the company's product manual 50 - as described
100000 hours, and optimistic, in fact, the life of the high-power led street lamp depends on the following points: (
1)
The chip quality and 1)
Led light source the light attenuation values.
(
2)
Light emitting diode encapsulation quality, consistency and reliability.
(
3)
Light-emitting diodes (leds) used as a cold light source, but the light emitting diode semiconductor itself get hot.
Light-emitting diodes (leds) heat dissipation to ensure that the light-emitting diodes (leds) good working conditions.
(
4)
The service life of the power source and constant current drive quality assurance.
2.
High efficiency energy saving lighting engineering is a systematic engineering, outdoor lighting and atmospheric lighting, by electric energy into light, and then through the lamps and lanterns, make a local lighting surface reaches a certain intensity of illumination, uniformity and color rendering.
Multiple lighting on the surface of the components are combined into a complete lighting engineering, cannot simply through the power consumption to compare, but through the comprehensive and integrated analysis.
3.
The difference between the traditional lamps and lanterns and semiconductor light-emitting diode lighting lamps and lanterns is composed of light source, power supply, lamps and other lighting appliance parts assembled.
They are also lighting, projection approach is used to control the light source and light, they can protect the light source and lighting efficiency at the same time.
The traditional street lamp lighting is mainly composed of lamp shell, light source cavity, electric room, etc.
Because it has enough empty space and the installation of sealing and activated carbon shell and foam silicone rubber heat dissipation, ensure the working conditions of the light source.
Light room reaches IP65, protection grade for IP45 electrical room.
The traditional street lamp can be made into any shape, as long as such protection conditions guaranteed.
Traditional design of road lighting lamps and lanterns is very good in our country, truly reflects the vision during the day and night vision.
However, with the emergence of semiconductor light-emitting diodes, street lamp, long life light source is unique, has simple and reasonable distribution of light, color temperature variability and the advantages of high color rendering index.
Low voltage large current source power supply has the trend of the development of high efficiency and energy saving.
Applied in the street lamp light emitting diode has its inherent advantages, including: 1.
As a point source, light-emitting diodes (leds) if the design is proper, can directly solve the traditional spherical light source must rely on light emission to solve the problem of the secondary light extraction and light loss.
2.
Can control the uniformity of the surface of the light, could theoretically be uniform in the target area completely, also can avoid the traditional light source;
The light is on.
Phenomenon of mild waste;
