Q:How to identify Ic constant current LED bulb?
The general user how to judge whether the bulb with constant current IC power supply, the general bulb is divided into three kinds, one is the RC driven RC drives are the most simple, because the cost is very low power small bulb and lamp using the scheme of small power LED bulb is often driven by RC, RC driving disadvantage is LED current with voltage fluctuation is changed, the brightness will change, so the resistance capacitance in the price is cheaper and less demanding bulb drive only, one with the IC LED driver, this there is also a constant current power supply, but the precision of constant current IC is not high, this power can only be used in the 220V voltage, the voltage fluctuation of relatively large area will affect the brightness of the LED lamp, and the stability of the power supply is relatively poor, life is better than Relatively short, easy to issue, this power supply is only a three - stage tube and two regulators circuit very...
Q:How does the LED bulb go with the power?
voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,
Q:What's the reason why LED bulb gets a lot of heat?
If the radiator has a large radiating area, the temperature is low
Q:LED how does the bulb return electricity?
A 0 ohm resistor with a large point on the negative electrode
Q:Led what's the flash of the bulb?
So, this is the power overheating protection at work. It will not be the case if the outer shell is enlarged or the room is ventilated and the heat should be cooled.
Q:What are the requirements of the LED series inspection specification for bulb bulbs?
Insulation resistance: the lamp should not be placed for 48 hours in the damp box with relative humidity of hours. The air temperature in the box shall be controlled at any value between 20~30 degrees centigrade, and the temperature difference is within 1 degrees. The insulation resistance shall be measured in the wet box. Now the DC voltage on the lamp is about 500V. After 1min, the insulation resistance test will begin. The insulation resistance between the lamp holder, the current carrying metal parts and the accessible lamp parts shall be no less than 4M ohms.
Q:LED bulb with what type of LED beads?
Of course, the more high-end heat better use EMC3030 lamp, EMC2835 lamp and so on, please consult your supplier
Q:LED bulb bulbs, do you need 3C certification now?
Light source class is impossible to do, only lamps and lanterns class can do. For example, flat lamp, ceiling lamp and so on...However, CQC voluntary certification can be done.
Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
LED bulb is broken. The luminous patch is not bad. It can be made into USB lamp.LED bulb is usually a series of LED series, and then parallel, generally about 12V.Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated.Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current.Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light to normal brightness, or it may damage the USB interface. It is better to use the USB charger interface.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.
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.
