What are the characteristics of LED downlights How to maintain LED downlights

　　 LED downlight features
　　1. Energy saving: The power consumption of the same brightness is 1/2 of that of ordinary energy-saving lamps.
　　2. Environmental protection: It does not contain harmful substances such as mercury and does not pollute the environment.
　　3. Economy: The cost of lighting can be recovered in one and a half years because of electricity saving. A family can save tens of yuan in electricity bills a month.
　　4. Low carbon: Saving electricity is equivalent to reducing carbon emissions.
　　5. Longevity: LED lamps have a lifespan of 100,000 hours. Based on six hours of use per day, one LED lamp can be used for 40 years.
　　 How to maintain LED downlight
　　 1. After buying back the lamp, don't be busy installing it. Read the mark of the lamp and read the installation manual, and then install and use the lamp according to the instructions, otherwise it may be dangerous.
　　2. Be careful not to change the structure of the lamp during cleaning and maintenance, and do not change the parts of the lamp casually. After the cleaning and maintenance, the lamp should be installed as it is, and do not miss or wrongly install the lamp parts.
　　 3. The lamp in the room should be wiped with a dry cloth frequently, and attention should be paid to prevent moisture intrusion, so as to avoid corrosion damage or leakage and short circuit after a long time; the lamp installed in the toilet or bathroom must be equipped with a moisture-proof lampshade, otherwise it will greatly shorten the use Life; the lamp installed in the kitchen should pay special attention to preventing oily smoke, because the accumulation of grease will affect the illuminance of the lamp; the light-colored lampshade has better light transmittance, but it is easy to stick to dust. Wipe diligently to avoid affecting the light penetration Degree; if the lamp is non-metallic, it can be wiped with a damp cloth to prevent dust from accumulating and hampering the lighting effect.
　　 4. Minimize the number of switches as much as possible. The principle of the lamp switch is to use the sharp rise of the filament temperature to accelerate the sublimation. Frequent switching on and off will cause the filament to heat up for many times, and the service life of the filament will be shortened if the frequency is too high, so do not switch the lamp too frequently.
　　 5. If there is a problem, replace it in time. Replace the aging light source in time according to the light source parameters provided by the logo. When replacing the light source, you must pay attention to the key items such as the light source type, interface type, power, and color temperature on the lamp logo. In particular, the type of light source should not be installed by mistake, otherwise It is very easy to cause explosions and other safety accidents (such as connecting low-voltage light sources to high-voltage lamps) or directly damage light sources and electrical appliances. At the same time, when replacing the light source, please pay attention to power off the lamp first, and then replace the light source of the same model and the same power after the light source cools down. Generally, the manufacturer of the lamp will have an obvious maximum limit for the light source in the lamp manual. Mark, please pay attention to choose a light source less than or equal to the maximum limit.
　　 6. Clean the dust on the lamp surface regularly. Statistics show that if the lamp accumulates too much dust, the average annual illuminance will be reduced by about 30%, so cleaning the dust can not only increase the service life of the lamp, but also make the lamp illuminance higher.
