Do you know anything about street lighting purchases?TEK lighting tells you
LED street light, because of its low power consumption, high luminous efficiency, long life, energy conservation and environmental protection, has gradually eliminated the traditional street lamps, becoming the "main force" of road lighting.The light of lamp lamp time is long, and installation is outdoors, cause sunshine and rain, so the quality of lamps and lanterns must pass pass.Otherwise, lamp damage, will pose a threat to road safety.Therefore, companies, institutions, or engineering companies need to be careful when purchasing street lamps to avoid falling into the procurement trap.
There are several pitfalls for LED street lighting procurement:
Trap 1， fake chip, low-end chip
The core of LED street light is the chip, which directly determines the performance of the lamp.However, some adverse manufacturers use customer unprofessional, from the cost of the above consideration, using low price chip, make customer buy the low quality of the product with high price caused direct economic losses, and causing serious quality hidden trouble of LED street light.
Trap 2 ，configuration virtual standard, exaggerated configuration parameters
LED street light, hot also with price lower profits, fierce competition also LED to many solar street lamps factory started to cut corners empty mark product parameters, wattage, battery capacity, and even light pole materials are in question.
Of course, this is also the customer repeatedly compare the price, the demand low price causes, also related to the practice of some manufacturers.Trap three heat dissipation design bad, configuration is unreasonable
Trap 3， heat dissipation design bad, configuration is unreasonable
In terms of heat dissipation design, The PN junction temperature of LED chips increases by 10 degrees,The life of a semiconductor device decreases with multiple times.Because LED street light brightness requirement is high, use environment is more rigorous, if the heat dissipation solution is not good, can quickly lead to the LED ageing, the stability is reduced.
Other unreasonable configurations often result in specific use cases that are not expected.
Trap 4， copper wire is posing as gold wire and controller problem
Many LED manufacturers are trying to develop other sources to replace expensive gold threads.Although these alternative is better than that of gold thread on certain features, but poor in chemical stability but many, such as silver and gold silvering alloy wire is vulnerable to sulfur corrosion/chloride/bromide, easy oxidation of sulfide copper wire.
For similar to suction breathable sponge encapsulation of silica gel, these alternatives to make wire bonding are more susceptible to chemical corrosion, the reliability of the light source is reduced, use time grew, LED lamp bead are more likely to break the dead light.
LED street light controller, the controller if there is failure, the process of testing and inspection, there will be a "whole lights is not light", "The switch is not on time" and "damage", and so on phenomenon.
