LED Street Lamps

LED street lamp

One-way 1, LED street lamp itself -- light, diffuse without light illumination efficiency, guarantee.
2, LED street lamps have two unique optical design, the light of LED street lamp to the desired lighting areas, further improve the light efficiency, in order to achieve the purpose of energy saving.
The light efficiency of 3, LED has reached 110-130lm/W, but there is still much room for development, the theoretical value of 250lm/W. While the luminous efficiency of high pressure sodium lamp is increased with the increase of power, therefore, the overall efficiency of light than the high-pressure sodium lamp LED street lamp; (the overall light effect is theoretically, light effect in high pressure sodium lamp above 250W is higher than LED).
4, LED street lamp light color is much higher than that of high pressure sodium lamp, high pressure sodium lamp Hin color index is only about 23, while the LED street lamp Hin color index reached more than 75, from the point of view of the visual psychology, to achieve the same brightness, illumination LED lamp can average 20% lower than high pressure sodium lamp, (with reference to the British standard truth lighting).
5, light a small decline, a decline of less than 3% years, 10 years and still achieve road illumination requirements, and high pressure sodium lamp failure, a year has dropped more than 30%, therefore, LED lamp can be used in the design of power than the high-pressure sodium lamp low.
6, LED street lamp automatic control energy-saving device can be realized in different periods, meet the lighting requirements of the maximum possible power reduction, energy saving. Spark intelligent LED street lamp can realize computer dimming, time control, light control, temperature control, remote control, automatic inspection humanized functions.
7, the LED is a low voltage driving device, single LED safe voltage, series products of single LED power is 1 watts, so it is safer than the use of high voltage power supply, especially suitable for public places (such as: street lamp lighting, industrial lighting, automotive lighting, the lighting etc.).
8, each unit of LED small only a small volume, so it can be prepared into various shaped devices, and is suitable for mobile environment.
9, long service life: can be used for more than 50000 hours, to provide three years of quality assurance. The deficiency is the life of the power supply can not be guaranteed.
10, high light efficiency: the use of ≥ 100LM chip, compared with the traditional high pressure sodium lamp can save more than 75% energy.
11, installation is simple: without buried cable without rectifiers, directly to the street lamp arranged on the lamp stand connected or nested original lamp light source.
12, cooling control outstanding: summer temperature control at 45 degrees Celsius, and the use of passive cooling method, insufficient heat protection summer.
13, reliable quality: circuit power all adopt high quality components, each LED is individually overcurrent protection, no need to worry about damage.
14, light color uniformity: without the lens, not to increase the brightness at the expense of uniform color, so as to ensure no aperture light color uniformity.
15, LED does not contain harmful metal mercury, unlike the high-pressure sodium lamp and metal halide lamp harm.
Based on the principle of high power LED street lamp, energy-saving effect of significantly, instead of high pressure sodium lamp can save electricity above 60%. (to be known)
Low maintenance cost: compared with the traditional street lamp, LED street lamp maintenance cost is very low, by comparison, less than 6 years to recover the full investment cost.
