LED Down LightThe light source of energy-saving lamps, halogen lamps, etc., and now the commonly used light source is LED.
LED light source has different classifications. Commonly, DIP LED, also known as plug-in LED, or called straw hat LED. SMD type [Surface Mounted Devices] originally refers to a form of packaging, used in the LED industry refers to SMD lamp beads, High power LED that is high-power LED, there is COB that is concentrated package of LED and so on. The earliest LED downlight useful straw hat LED, now basically do not use. 1w or 3w high power led alone for downlight has become less and less.
Now most of the use of SMD and COB. SMD light uniformity, long life, relatively simple process, cost-effective. COB has good color difference and good heat dissipation. Both LED light source has its own advantages. Relatively speaking, COB cost a little more.
LED Down LightIn addition to the advantages of general LED lighting, such as energy saving, environmental protection, long life, etc., but also has some other advantages, such as: directional lighting, accent lighting.
In the main lighting, LED downlights play the role of auxiliary lighting, such as sofas installed downlights, conducive to reading books and newspapers on the sofa, open the downlight, you can see more clearly. No main lighting will be used in a large number of downlights, so that in addition to meeting the basic lighting needs, but also allows the light to be more layered.
