LED bulbs use LED lamp beads as a light source, which is environmentally friendly and energy-saving. In 2013, the sales volume of LED bulbs will soar!
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 casings 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 indicates that the interface is a screw, and 27 indicates that the screw diameter is 27 mm. The most intuitive comparison method is to compare coins: a one-dollar coin is 25mm in diameter, smaller than the E14 screw, and 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.
