Street light is a basic foundation kit in roads to guarantee the security from accidents. and they are related to happiness and reducing unfortunate events. Currently, street light is a led device to use in outdoor lighting and they mainly consist of a capacitor, a resistor, with a triode and a MOS tube, and a basic composition that makes it common to many components.
In addition to those mentioned above, it also has the fact that it does not contain mercury that is destructive to the earth and our health, and is more convenient in terms of ecological treatment. LED street light become more safe, besides, it is can operated steadier in low voltage condition. In addition, LED street lights have a better visual experience with a longer lifespan about 100,000 hours and they are more energy saving, with high light efficiency.
Therefore, LED street light retrofit is getting faster and faster. In terms of retrofits, manufacturer for LED street light retrofit replacement in HID and HPS with simply and easily installation, can realize to quickly adjustable LED lighting without any problems.
The following are the quality factors for good power supply:
l Minimum 10KV surge protection
l IP66 protection rated
l Ground connection with surge protection.
l Overcharge protection, over-discharge protection, over current, short circuit protection.
l Power supply can be easily replaced in the field without tool-free and removing it from the pole.
l Adopts the isolated driver solution.
Maybe you will wonder why the LED chip is not the most important one. Actually, if you choose the best power supply, LED chips have unlimited life in theory, that is because LED chips is a solid-state hardware with its efficacy decreases over time. There are many outdoor lights, especially led street lights, they would be damaged by its own poor structure, but it is not the only one factor, may have more reasons, here are some examples:
l Waterproof rating does not meet the standard requirements
l The radiator has no anti-corrosion coating
l The luminaire does not have sufficient pressure resistance
l Waterproof rubber ring is not good quality
l Anti-corrosion coating to withstand harsh weather
l Professional secondary optical lens
l IP66 and IK08 protection rated
l Rugged appearance for weather protection like typhoon weather
l Using outdoor special stainless-steel screws and other exposed accessories
l Aluminum alloy material with chemical treatment to resist rusting
l The distribution of street lights
l Uniformity of light distribution
l Standard of average illumination
l Lumens (Light output) of streetlight
l The light is distributed asymmetrically by professional lens.
l Less attractive to insects at night
l Low glare to avoid affecting the driver's
Also consider following factors for streetlight wattage and Pole height: the standard of installation space for led street lights
l 3-6-meter height poles are suitable for below 100 watts
l 4-8-meter height poles are suitable for 100-150 watts
l 8-12-meter height poles are suitable for above 150 watts
