Teach you how to identify the quality of LED ceiling lamp

Now on the market a lot of LED ceiling lamp types, the quality of what is, then how to identify LED ceiling lamp quality is good or bad? First of all you have to understand LED days lantern costs from which a few respects, I summarize LED ceiling lamp cost into five parts:
Cost: the shell and the radiator
Cost: two beads (chip)
Cost: three driving power supply (commonly known as the transformer)
The cost of four: aluminum plate, lens, wire, accessories, packaging costs, loss, the wages of the workers
The cost of five: rent, hydropower, tax, interest, management fees, manufacturers profits
Through the introduction above, we can see the LED ceiling material cost from the previous four, next I simple analysis of how to identify the quality of LED ceiling lamp:
1, LED days, LED days lanterns shell and the radiator shell and the radiator used materials are mainly copper, aluminum, PC, the thermal conductivity of copper is better than the aluminum, aluminum heat better than the PC, now the most generally used aluminum heat sink material, the best for inserting sheet aluminum, aluminum (aluminum profile, aluminum extrusion) times, the worst is the cast aluminum, aluminum radiating effect best insert! Resolution of the shell and the radiator is good or bad, will have a look the shell and the radiator thickness, height, accuracy, surface treatment. The shell thickness and size of the radiator, heat is directly related to the LED days, LED days lantern, radiating very important, LED ceiling lamp the same power factors and the same quality beads, if the heat condition is not good, lamp work under high temperature, light will very soon, the service life of the lamp is greatly reduced.
2, LED days lantern lights: bulb quality depends on the chip quality and packaging technology.
The LED lighting chip brand in three grade:
High end to Japan as the representative of the European and American,, including CREE, Osram, Nichia chemical, Toyota synthesis;
In the end, to USA Korea, China Taiwan as the representative of the manufacturer, mainly including the prefect, Xu Ming, Seoul, wafer, Taigu, light macro, new century etc.;
The lower end of the domestic as the representative of the manufacturer, mainly has three, di yuan, blue, Shilanmingxin, Lu Mei etc.. The chip quality decides the brightness and light bulbs. Good beads not only high light flux, but also small attenuation, the price difference is very big, the same one watt bulb, chip and package technology is different, the price difference reached 3-10 times, ceiling lamp special low price, so many defective products using the chip production line lay to make, the color temperature is not consistent the difference in brightness, short service life.
Driving power supply 3, LED days lantern (commonly known as the transformer): Theory of life LED days lantern beads in the 5-10 million hours, but the supply is short board LED days lantern, the life of the power supply is based on quality is usually 3000-20000 hours of life, the power supply if the bad words, the whole lamp is bright not the.
Quality, design scheme of electronic components used in power determines the power efficiency, power factor, stability, temperature rise, service life. The power efficiency is higher, higher power consumption itself shows the smaller, the stronger the power is output, MeiErTe optoelectronic products lamp factory are going after the aging test of high and low voltage electric shock 24 hours or so, if the lamp is not qualified in high and low voltage electric shock quickly broken, after aging test can greatly improve the qualified rate of the products.
4, LED downlight aluminum substrate, lens, conductor:
LED ceiling lamp aluminum substrate is improved to LED radiator to dissipate the heat conduction, thermal conductivity and other material of aluminum base material aluminum alloy substrate material is related to the amount of copper and silver, if you add other materials with high thermal conductivity, coefficient of thermal conductivity of aluminum substrate material is high, mass resolution aluminum substrate surface, mainly have a look the technology, thermal conductivity, aluminum substrate Naibunai pressure, too after reflow soldering board will not yellow. LED ceiling lamp lens for silica gel lens, the lens can enhance the LED of the optical system for light field distribution of optical efficiency, lens change LED. LED ceiling lamp wire: minimum cut wire area using LED ceiling lamp on the 0.5mm/ square. Wire cross-sectional area some nonconforming product with only 0.2mm/ square, the wire in the abnormal state, will make the wire burning, short circuited insulating layer is burned, dangerous.
5, rent, hydropower, tax, management fees, interest, profits of fifth major manufacturers cost according to the actual situation of various manufacturers and decide, here not elaborate on one one. Now the market quality and price LED days lantern is various, dragons and fishes jumbled together, as to how to choose depends on your needs, remember a bit, if is the ordinary family inside, the general family don't have LED days lanterns as the main lighting lamp, every point of time is not long, can choose the price point, if you are using LED ceiling lamp, hotel, shopping malls and other places of business, must choose Shenzhen LED LED ceiling lamp, lamp manufacturers of high-quality, like these illumination time to be as long as 13 hours, if the cheap LED ceiling light quality is poor, cannot use a year might not be in these places, so down the maintenance cost is very big, do not try.
