Q:Who knows where the broken LED bulb is?
Common problems, a lamp is broken, the heat is not good cause, most likely it is a bad driver. As for the aluminum substrate, it should not be bad
Q:LED bulb bulbs, do you need 3C certification now?
No, this is a light source, not a lamp. It can only be CQC voluntary certification
Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
General household enough, if in 10 square meters of housing, installation of more than 10W LED lights, brightness is too good, if not the study, it is best not to.
Q:Will the power of the LED bulb grow longer and longer? Why?
Voltage problems, as well as unstable factors.Long time no change, should
Q:What are the characteristics of LED bulb?
The service life is long, and the average life can reach 100 thousand hours.
Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
If the material with better thermal conductivity, the lamp shell about 60 degrees is best.Reason:1: if the temperature is too high, that your radiator is too small.2: if the temperature is low, indicating that your calories did not lead out. (of course, if the radiator is too large and the temperature is low, but the bulb and tube are too heavy to pass by certification)
Q:LED what does "A60" mean by bulb 60? And what does "MR16" mean?
MR is a reflector that is represented by a plurality of reflector groups, and 16 represents the maximum outer diameter of 1/8*16*25.4=50
Q:Why can't the voice switch control the time of the LED bulb?
The production lights can be controlled. Where do they go to consult?
Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
It's best to use heat conductive glue, such as ST922.
Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?
The difference of power factor is large, and the resistance capacitance pressure drop is below 0.5 PF. Constant current and constant voltage drive PF over 0.9. The resistance drop pressure is really attractive, after all, the price is there. The average person doesn't understand the look.
