Led bulbs use led lamp beads as a light source, environmental protection, energy saving, sales of led bulbs will soar in 2013!
Matters needing attention: The most important thing affecting led lamps is heat dissipation. The high thermal conductivity is aluminum alloy, so manufacturers who do LEDs generally choose aluminum shells with better quality.
Causes the high-power bulb to be used above normal temperature:
1. The current is too large.
2. The quality of the lamp bead is too bad.
3. The structure of the aluminum radiator is unreasonable and the heat dissipation is not good.
4, the use of ambient air flow is poor.
skill:
1, look at the color, the more pure the color, then the higher the quality of the product.
installation:
At present, the LED bulb interface is mainly E14\E27 interface, E means the interface is screw, and 27 means the screw diameter is 27mm. The most intuitive comparison method is to compare with coins: the diameter of a one-dollar coin is 25mm. The small one is the E14 screw, which is larger than the E27 screw. Of course, this is just a rough way to be used.
1. Consumers should pay attention to whether the interface matches when purchasing.
2. When installing and replacing the lamp, you need to completely turn off the power before proceeding.
3, avoid installation in high temperature, high humidity and close to the heat source and hot steam, corrosive gas, so as not to affect the life.
