First, how to choose the kitchen ceiling lamp
1, depending on whether the workmanship is fine, good LED lights require higher requirements in all aspects, such as dust prevention, moisture prevention, lightning protection and so on.
2. Looking at the power factor of the whole lamp, the low power factor indicates that the used driving power supply and circuit design are not good, which will greatly reduce the service life of the lamp, and the service life of the lamp with the best lamp bead will not be long. The level of power factor can be detected by the power factor table! Generally above 0.85.
3. The quality of the lamp bead depends on the packaging process and chip quality. The quality of the chip determines the brightness and light attenuation of the lamp bead. Good lamp beads not only have high brightness, but also have small light attenuation.
4. Look at the driving power supply used by the lamps, the service life of the power supply is much shorter than that of other parts of the lamps. The service life of power supply affects the overall service life of lamps. The theoretical life of lamp beads is 500-65438+10,000 hours, and the life of power supply is 0.2-30,000 hours. The design and material selection of power supply will determine the service life of power supply.
5, look at the light efficiency, the same lamp power, the higher the light efficiency, the higher the brightness, the same lighting brightness, the smaller the power consumption, the more energy will be saved.
6. Look at the power efficiency, the higher the power efficiency, the better. If it is higher, the power consumption of the source itself is smaller and the output power is larger.
7. See if it meets the safety standards. The safety standard of LED lamps in China has been issued. Please select LED lights according to the national safety standards.
Second, how to clean the ceiling lamp in the kitchen?
1, crystal bead wiping:
When wiping beads, be sure to dip a soft cloth in water diluted with detergent, and then gently wipe the front and back of the crystal beads at the same time (you can't hold down the beads when wiping, so as not to damage them).
2. Keep the lamp body balanced:
If all the lamp beads are to be removed for cleaning, attention should be paid to the balance of the lamp body when removing the lamp beads for large lamps, so as to avoid the lamp body tilting and deformation of the lamp body or the outer frame due to the removal of one side and the other side; When disassembling, it is necessary to cooperate with disassembly before and after.
3. Wipe the bracket fittings:
When wiping the bracket and accessories, the soft cloth should not be stained with water, especially alcohol water, so as not to damage the protective film outside the electroplating layer and affect the surface gloss effect of the lamp holder.
4. Pay attention to safety:
When wiping the lamp holder, cut off the power supply; The light bulb should also be removed, wiped clean and then installed; Screw in the bulb moderately, too loose will cause poor contact; Too tight may damage the light bulb. If you want to give full play to the effect of crystal lamps, it is best to choose ordinary transparent bulbs instead of frosted or colored bulbs.
5, timely replacement of accessories:
It is found that the beaded connection buckle is rusty and discolored, which is unsightly and fragile. It is best to replace it by the way. If bead string defects are found, they should be filled in time.
