With the developing of LED street lights, some manufacturers just want to get high profits, lead to a large number of unqualified products enter the market, against the LED street lights' real value of energy-saving, long life, environmental protection and so on. How to distinguish the good and bad LED street lights, there are some tips for you:
First, the overall appearance. Lights produced by the major LED lighting manufacturers have smooth appearance, rich texture. Through multiple processes processing, the light surface will never rust or fade.
Second, the circuit design. If circuit design was not good, it would greatly reduce the lamp life, low power factor, no matter how good the lamp bead is, the lamp life would not be long.
Third, the quality of light bead. The quality of light bead decides the chip quality and packaging technique. In order to reduce costs some small manufacturers use the low quality light beads.
Fourth, the driving power. The power life directly affects the lamp life, lamp bead theoretical life is about 50,000-100,000 hours, while the power life is about 2,000-30,000 hours. Power design and material will determine the life of the driving power.
Fifth, cooling. Cooling is also very important, if the cooling ability is not good, lamp beads work at high temperatures would lead to a large droop, lamp life would be reduced.
Sixth, safety standards and certification. Good quality LED street lamps are tested by professional equipment.
A good quality LED street light besides has the aspects mentioned above, according to different environments have different technical requirements, such as moisture, dust , magnetic , anti-lightning.
