LED lamp with low carbon, energy saving, environmental protection and service life longer by the majority of consumer recognition and acceptance, and shall be used, but with the current LED lighting market's rapid expansion, now LED lighting products good wilt on the market is not neat, now on the market at present widely used LED ceiling lamps products, Zhongshan Saint Magnus LED lamp manufacturers here roughly with everyone to do a simple introduction and analysis;
LED ceiling lamps and all LED lighting products mainly consists of three parts;
1, LED light source:
At present the market above LED ceiling lamps light source can be divided into high power light source and a small power source two categories; high power light source with high power LED lamp bead main 1W; small power source is 0.5W, 0.2W, 0.1W, 0.06W and so on the many kinds of specifications, the source of which the current market is the most used 0.5W 5730 beads;
How to distinguish between simple difference LED ceiling lamp light source, the simplest approach is also lit the same brand of the same specification size power ceiling lamps, remove the mask, see the spot on the white wall, if the brightness and color to achieve the same light source, is the brand of the good good coherence light source products if it is on the wall, showing a variety of colors, can determine the brand LED ceiling lamps light source adopts differential is too messy, generally is often appear at the source problem; the second is can take different brands of the same power size lamps lit removal mask, under the same power, the light source brightness level of ceiling lamps the higher the brightness of the light source will be higher, because the higher price will be higher than the brightness of the light source is low;
The 2 part, radiator:
Because LED ceiling lamp cooling is to play a cooling effect through the substrate connected with the chassis, so the first substrate LED ceiling lamps, currently on the market, LED ceiling board part mainly has several lamps; the first is with aluminum plate, aluminum plate as everyone knows the heat will be better than its his substrate, so the aluminum substrate as the LED the light source of the substrate ceiling LED lamp manufacturers generally use to illustrate the manufacturers, LED ceiling lamps is also more responsible, taking into account the heat treatment of the LED light source, second is made of fiberglass panels, third by using cardboard (paper PCB); second, third; basically is the substrate current low-priced LED light source ceiling lamps can see, LED lamp manufacturers use the two substrate basic didn't take into account the problem of heat dissipation of the LED light source, regardless of LED light source life, solid Ze and fishing reduced LED life to achieve the purpose of reducing cost, so the general sellers see this architecture LED ceiling lamps, used with caution;
Another part of LED ceiling lamps heat can do local heat dissipation through the chassis, so general in the selection of LED chassis, normally there are two considerations, the first thickness of the chassis, the chassis of the thickness is currently on the market there are 3, the first kind is 0.3 steel, 0.35 steel plates with second, third is 0.38 - 0.4 of the plate, the chassis plate adopts the more thick, tensile strength of LED lamps is higher, heat divergence as a whole is better; second considerations, in order to ensure good heat dissipation, a lot of high order LED ceiling lamps will process using aluminum chassis in the selection, to ensure the heat dissipation LED ceiling lamp;
3, power supply;
LED ceiling lamp power source and the LED lighting products to others, using constant current drive to ensure the normal work and life of LED, but in many low-cost LED ceiling lamps products above can also see cheap RC driving power supply, power resistance capacitance drive is through the resistor and capacitor to realize the pressure drop. With the power supply voltage fluctuations arising from external LED drive current fluctuations in the city power voltage instability in the region, the light will flickering, the existence of stroboscopic phenomenon is serious, in this light a long time easy to produce visual fatigue caused by eye eyesight drops; it is generally recommended not to use the cheap products scheme;
To sum up, roughly LED ceiling lamps of the main differences have been described to you, in some high order products, in order to meet different user illumination demand, do things like dimming, remote control functions, here is not one one introduction, the hope can help to you buy for their own LED ceiling lamps products.
