Now the mainstream market is still energy-saving lamp tube type ceiling lamp, led ceiling lamp is relatively less, one of them: the price factor, the second: led is not too mature, many people still do not know or accept this . But as a new thing, the development of led is still very fast, replacing the energy-saving lamps is also in the near future.
Led is developing too fast! ! ! As a result, the products on the market today are also uneven. All LED products are nothing more than three big blocks: drive power; heat sink; chip. But today's led ceiling lamps are still much more about shades, bases and aluminum substrates.
When the market is going to buy a lamp, everyone knows more or less about this. When buying in a lighting store or an online store, the merchant will instill more knowledge of led.
As for the driver power, heat sink, chip, I have talked about this home improvement strategy, interested can go and see: http://
Now let's talk about the lampshade, the base, the aluminum substrate.
One: lampshade
This is a question of face, which can be seen at a glance. In the general market, there are acrylic and PVC. Acrylic's more high-end, secondary stretch acrylic mask.
Here I take a few pictures to see
Secondary stretch acrylic mask
This is a secondary stretch acrylic mask. First: its light transmission is good, the light transmission performance is over 90%; second: no dark area, that is to say, the whole mask can not see any darker places, the brightness is even; third: can not see the light source LED light source is still very glaring, you can definitely look bad on your eyes.
Acrylic mask
This thing, in the market is still very common, generally this, selling a few tens of dollars, this is still relatively conscience selling, this is indeed acrylic. There are also unconscionable businesses, do a PVC (that is, plastic), that stuff is jealous. When you buy it, you can let the owner fold it a bit, and see if it is broken in an instant, but don’t fold it yourself. If it is broken, it will be troublesome.
Second base
The base is also generally plastic, but there are also steel. Of course, steel is considered for heat dissipation. Generally, it is made of steel. The quality is definitely good. If the price is also considered, the price can also be considered.
The above picture shows these two
This is a steel chassis
This is a plastic chassis
Three: aluminum substrate
The quality of the aluminum substrate is also a very large factor. The quality of the aluminum substrate naturally affects the quality of the entire LED ceiling lamp.
A better aluminum substrate covers the entire ceiling lamp. It is almost an aluminum base ring or an aluminum base strip. The aluminum base ring or the aluminum base strip naturally produces some dark areas. The quality of these second aluminum substrates is still relatively poor.
The above picture shows the difference between the two
Aluminum substrate with uniform chip distribution
Annular aluminum substrate
This also has a disadvantage, that is, it is easier to enter the mosquitoes. This loophole is inherently many. The led ceiling lamp can be sold for 50 or less. I don’t think you should consider this kind of thing, but some people will I think it's cheap, I don't want to use it for a long time, then you can buy it.

DC fan editing
Cooling fan, is through the DC voltage and electromagnetic induction, from electrical energy into machinery to promote fan rotation fan.
Rely on the coil and IC constantly switch, induction magnetic ring from the drive fan rotation.
Electric energy into machinery to promote the fan rotation
The rotor of the DC cooling fan includes the DC cooling fan blades, which is the source of the air flow, the fan shaft, which is used to support the balance blade rotation, the rotor ring, the permanent magnet, the key to switch the speed of the magnetic level, Fixed magnetic ring. In addition, it also includes the support of the spring, through which the components are fixed to the tuberculosis to rotate the entire part, the motor part, the production rotation direction, and the dynamic size of the rotation speed key. Its speed performance, control is simple.
