The LED ceiling light is a kind of ceiling light that chooses LED as the ceiling light. It is installed in the room with a flat shade and close to the roof. A tube is on the roof and the LED ceiling light is installed at the bottom.
One. Ordinary ceiling light
Although there are many kinds of ceiling lights, the most common ones are round lights or round lights, but the common ones can be crystal ceiling lights with a variety of shapes:
Lamp tubes of ceiling lamps: Most of the lamps are bent T5 lamps. The specifications of the ceiling lamps are as follows. There is no clear regulation on the power of ceiling lamps. The most commonly used power is 10W, 16W, and 21W. , 28W, 32W, 38W, 40W, etc.
two. The problem and the reverse side of ordinary ceiling lamps
Low luminous efficiency
Because most of these ceiling lights use T5 type tubes, which are bent into various shapes. But no matter what shape it is finally bent into, it emits light in 360 degrees, where the upward 180 degrees of light reflected and reflected will turn into individual light, and there will be a lot of light during this reflection process.
Three, the advantages of LED ceiling lights
High luminous efficiency: The luminous efficiency of LED has reached 130lm/W, so the overall luminous efficiency of LED ceiling lamp can reach 100lm/W. And this efficiency is still growing. It is estimated that by 2020, the luminous efficiency of LED light will reach 240lm/W. High light efficiency means energy saving. According to the measured results, one 8W LED can sample a 32W ceiling lamp. Electric power can be saved more than 4 times.
Long lifespan: LED has a lifespan of 100,000 hours. After it can be made into a lamp, it can now be believed to have a lifespan of at least 30,000 hours, 50,000 hours for lightning, and more than 10 times longer than fluorescent lamps. The final life of the three-color magic lamp The life span is 10,000 hours, which is more than 5 times higher.
Other advantages: no alcohol, no light, no light pollution, and can provide various color temperatures of 50-3700ºK and 4700-7000ºK. No glass spectrum, resistant to shock, vibration, and transportation. No need for aluminum, low cost and light weight.
