What Factors Determine The Quality Of LED Lanterns?

LED lights, belong to LED indoor lighting, in commercial lighting and home lighting is widely used for auxiliary lighting and main lighting, but the quality of LED lights on the market is uneven, if you do not pay attention, it is likely to buy poor quality products.
1. look at the LED lantern housing and radiator: LED skylight lamp housing and radiator materials are mainly copper, aluminum, PC, etc., generally speaking, copper heat dissipation is the best, aluminum second, PC the worst, but the cost of copper is too high, so the general heat dissipation equipment are more aluminum, aluminum insert, car aluminum, cast aluminum, etc., which insert aluminum is the best, car aluminum, cast aluminum replacement. In addition, you can also see the thickness, height, accuracy and surface treatment of the shell and radiator, etc., the thickness and size of the radiator will be directly related to the heat dissipation of the LED sky lamp. The heat dissipation is good or not, and directly affects the life of LED lamps.
2. look at the LED lantern beads: Lamp beads will directly affect the quality of LED lights, the general chip is divided into three grades, the first is the high-end Europe and the United States, Japan as the representative of manufacturers, such as Cree, Osram, etc., the second is the United States, South Korea, Taiwan as the representative of manufacturers, such as Purui, Seoul, crystal, light macro, etc., the third is the representative of domestic manufacturers, such as SAN An, Di Yuan, Blu-ray and so on. The first quality is high, the price is naturally high, the second quality can be, the price is moderate, the third quality is poor, but the price is cheap, at present, many domestic LED lamp manufacturers in order to save costs, fight a price war, they use the third chip, the quality of the results can be imagined, therefore, consumers in the purchase of LED lanterns, do not blindly look at the price, cheap no good loan, There is truth in that.
3. look at the LED lantern driving power: Drive power, will be directly related to the life of the LED lamp, the theoretical life of the LED lamp bead can reach 5-10 hours, but if the power supply is broken, the life of the lamp bead is longer, therefore, the power supply is the short board of the life of the LED lamp, the life of the power supply, according to the quality of the good or bad, the life of the LED lamp is 3000-20000 hours, therefore, It is necessary to choose a good power source.
4. look at the LED sky lamp aluminum substrate, lens, wire: the role of aluminum substrate is mainly to transmit the heat of the lamp bead to the LED radiator, therefore, the quality of aluminum substrate is related to thermal conductivity, if the aluminum substrate adds high conductivity materials such as copper and silver, the quality is definitely better, in addition, you can also see the surface process edge, the board will not yellow. The lens is generally a silicone lens, and the lens quality is good, which can improve the light output rate of the LED and change the light field distribution of the LED. LED wire, good wire, the minimum cross-sectional area of 0.5mm/ square, and poor quality wire, cross-sectional area of only 0.2mm/ square. Poor quality wire will be burnt wire, short circuit and other dangers.
Of course, not only LED ceiling lights, for the choice of other LED lamps, but also partially refer to this standard, such as LED ceiling lights, LED downlights, LED bulb lights, etc., can also be judged from the above aspects.
