Now the mainstream market is still the energy-saving lamp tube type ceiling lamp, LED ceiling lamp is relatively less, one of them: the price factor, the second: led is still not 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 the lampshade. When the base and the aluminum substrate are now in the market to buy the lights, everyone knows more or less about this. When buying in a lighting store or online store, the merchants will instill some knowledge of led as far as driving power, heat sinks, and chips. I have talked about this in my home improvement strategy. If you are interested, you can check it out. Now let's talk about the lampshade, the base, and the aluminum substrate. One: The lampshade is a problem of face. It 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 the secondary stretch acrylic mask, which 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 directly look at the acrylic mask that is not good for the eyes, this is still very common in the market, generally this, sell a few dozen dollars, this is still relatively The conscience is sold, 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. Don't fold it yourself. If it is broken, the base of the two bases is also plastic, but there are steel, steel is of course considered. To heat dissipation, generally made of steel, the quality is definitely very good, if the price, you can also consider the above picture. These two are steel chassis. This is the plastic chassis. The aluminum substrate is good or bad. It is also a very big factor. The quality of the aluminum substrate naturally affects the quality of the entire LED ceiling lamp. The aluminum substrate covers the entire ceiling lamp. It is almost an aluminum base ring or an aluminum base strip. The aluminum base ring or aluminum base strip will naturally produce some In the dark area, the quality of these aluminum substrates in the second phase is still relatively poor. The above two differences between the two types of aluminum substrate circular aluminum substrate are also a disadvantage, that is, it is easier to enter the mosquitoes, this loophole has many, Led ceiling lamps can be sold for 50 and 50 pieces. I don't think you should consider this kind of thing, but some people think it is cheap, I don't want to use it for a long time, then you can buy it.
