Q:How to identify Ic constant current LED bulb?
Look at the power supply, there are a few simple electronic and capacitive circuit board, it is not constant flow, cross flow is larger, so understand? Cross flow IC, that is, the meaning of intelligent voltage regulator, so that the LED is not easy, bad capacitor driven LED is relatively easy to damage, easily breakdown, and power consumption than the cross flow
Q:What is the AC voltage of the LED bulb?
The conventional way to make multiple voltages is the 90V-240V ~50/60HZ 12V
Q:Who knows where the broken LED bulb is?
The proposed open, lamp is broken, can find light black or other unusual circumstances, bad power supply at the circuit board and components have the same burn what, under normal circumstances is such.
Q:LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
How many seconds delay? It won't take so long. How many bulbs do you usually soak in 0.5 seconds? A squeaky noise is usually a transformer or inductance whistle, and at least it shows a poor manufacturing process.
Q:What are the types of LED bulb?
According to the interface, the LED bulb has GU10, E14, E27, E40 and so on.
Q:How did the trademark on the LED bulb go up?
And the use of silk screen or pad printing, this is the need for the corresponding ink, this solution with a dedicated solution can be dissolved, and also have some prominent hand touch.
Q:LED bulb with what type of LED beads?
There are many LED bulbs with LED lamp types, different lighting manufacturers will adopt different LED models, at present, most of the 2835, 5730 beads, beads are 0.5W-1W LED beads, specific type: PL-P2835DW-C8-R3-C2/ PL-P5730EDW-C8-R3-C2
Q:What's the cause of the noise during the aging of LED bulb bulbs?
Either AC or DC LED lighting there will be a power module, a small hidden in the lamp body, the daily working state can produce high temperature, if the AC power supply temperature will be higher, because the lamp body appears to flicker, high temperature and long time will lead to the power supply module parts welding, weld or aging, so a lot of alternating current LED lighting the metal shell, to facilitate heat dissipation, the DC power supply is adopted to eliminate the flicker, reduces the electrical power, so the DC temperature should be low.
Q:What are the characteristics of LED bulb?
Less power consumption, a 5 Watt LED bulb, equivalent to 40 watts of ordinary incandescent.
Q:LED can the bulb be used in the bathroom?
Ordinary bulbs can be used in the bathroom, the bath water, protection grade ordinary bulb is not high, it is easy to make when water vapor lamps or rust element short circuit failure and cause some accidents. The bathroom is suggested by the power supply lamp, lamp waterproof plate etc..
