Q:Know the LED lamp wattage
There are regular W, 5W, 7W, 9W, 12W, 15W, 18W, 20W and so onSpecial requests can also be made if you have special needsIf you can tell me what you do, I can give you the recommended power
Q:How to choose the right LED downlight
Look at the power supply lamp (commonly known as: transformer) transformer quality also determines the whole life of the lamp, lamp used more than 50000 hours no problem, but if the transformer is destroyed, the whole lamp will not light up. The electronic components and design scheme in the transformer determine the efficiency, power factor, stability, temperature rise and service life of the transformer. Our driver is wide voltage drive, and the output current and voltage are stable.
Q:Home LED lighting downlight is broken, want to change themselves, I would like to ask how to remove ah? Where do you start?
Is the driver bad or lamp plant bad, general driving problem
Q:LED lamp power off why would light up
To understand electricity, CBB downlight electric capacitor in the AC input terminal 2 connection between bridge above, 1 pressure capacity of 400V 0.22 micro method and above, good quality point, usually you can solve your problem.
Q:LED lamp is mainly used in where
Downlight is generally used in shopping malls, offices, factories, hospitals and other indoor lighting, the installation is simple and convenient for people to love. LED downlight downlight all inherited the traditional advantages, less heat, energy saving and long service life, small maintenance costs. The early LED lamp LED lamp due to expensive, the overall cost is very high is not acceptable to the customers. With the decrease of LED lamp chip prices and cooling technology improved, laid a solid foundation for the LED lamp into the commercial field.
Q:Why use LED lamp light source patch
The patch LED can be fabricated directly on the aluminum substrate and directly cooled to the aluminum substrate to save heat, packaging costs and reduce thermal conductivity losses.
Q:The office, sample room, corridor, the most commonly used several LED downlight which is several dimensions, what is power?
You should use big ones. My home is small, 5W's PL*D005
Q:What brand of downlight is good? Please explain the reason, thank you!
Value. Of course, a person's life is not all activities, just for money, the pursuit of fashion, to accept new things, but also a way of life!
Q:How to judge the quality of LED downlight
A good LED downlight, design not only to see it the radiator, but also its driver, the core part will have to see it with the chip, which is what we call the LED lamp.
Q:Led downlight can light panel directly with intelligent dimming Mody?
The lights can only be switched on, because the way LED works is different from ordinary incandescent lamps, and dimming panels designed for incandescent lamps cannot hold LED. If you are using the lamp holder and driving split LED light, you can choose an output voltage, current, the same, to support dimming drive to replace the original driver, in order to achieve dimming
