LED lamps mainly applied to urban expressway,thingseses,times,factories,amongst the school,gardens,all sorts of residential area,garden road lighting.
Detailed introduction to LED street light:
1, LED street lamp itself characteristic -- light mono-direction, no light, guarantee the diffuse light efficiency.
2, LED lamps have the unique second optical design, LED the illumination lamps for the area, further improve lighting light efficiency, in order to reach energy-saving purpose.
3, LED light source efficiency currently has about 110-130lm/W, and very big development space, theoretical reach 250lm/W. And the high-pressure sodium lamp is luminous efficiency with power increase just increased, therefore, the overall efficacy than high-pressure sodium lamp LED street lamps strong; (this overall efficacy is theoretical, high power LED lamps advantages
In fact 250W above high-pressure sodium lamp efficiency than LED).
4, LED street lamp light color rendering much higher than high-pressure sodium lamp, high-pressure sodium lamp show color index only 23 or so, and the colour developing index reached LED street lamps, from visual psychology more than 75 Angle consideration, achieve the same brightness, LED street lamp light than high-pressure sodium lamp can reduce the average 20%, the British truth lighting (see standards).
5, LED street lamp light, the light of decline small decline less than 3% a year, use 10 years still reaches road use intensity of illumination requirement, and high pressure sodium, a year or so light failure has fallen more than 30%, therefore, LED lamps in the use of power design can lower than high-pressure sodium lamp.
6, LED lamps have automatic control energy-saving equipment, which can meet different time lighting in the largest possible requirements of lower power, save electricity. Spark intelligence LED street lamp can realize the computer dimmer, points, the light control period control, temperature control, remote control, automatic checking etc humanized function.
7 and leds are low-pressure device, driving the voltage single for safe voltage LED, series product single LED for 1 watts of power, so it is a high voltage power supply safer than using the power, is particularly applicable to public places (such as: the street lamp lighting, minding lighting, automotive lighting, civil lighting, etc.).
8, each unit LED small pieces and only small volume, so can preparation into various shapes devices, and suitable for changeable environment.
9, long life: can use 5 million or more hours, provide three years of quality assurance. Deficiency is power life unreliability.
10, photosynthetic efficiency high: the more than 100LM p chips, compared with the traditional high-pressure sodium lamp can energy-saving 75%.
11, installation is simple: no add buried cable directly without rectifier, installed on the street lamp light pole connected or will light nested original lamp shell.
12, thermal control well: summer temperature control in 45 degrees below, and USES the passive cooling pattern, inadequate protection of summer heat.
13, reliable quality: circuit power all using high quality components, each star LED have independent over-current protection, need not worry about the damage.
14, light color uniform: don't add lens, not to increase brightness and sacrifice uniform light color, thereby ensuring no aperture light color equably.
15 and leds do not contain harmful mercury, unlike high-pressure sodium lamp or metal halide lamp when the scrap of environmental harm.
