Q:Is it possible to manually weld LED bulb bulbs?
You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off
Q:How to choose the bulb power?
If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.
Q:What brand of LED bulb is good in quality?
Look at the bulb of the bulb. The so-called bubble shell refers to the transparent glass shell in front. In incandescent lamps, all are made of glass. But in LED bulbs, though they can be made of glass, they rarely do.. Because the LED bulb weight than incandescent lamp 5 times or more, if made of glass, fell on the ground, it broke the possibility of large. As a result, more LED bulbs are made of plastic to prevent them from breaking. And the LED bulb went out because the heat from the radiator, so the bulb Everbright is visible light, infrared heating has little, so the use of plastic to make foam shell will not damage due to heat.
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:What are the driving IC used in LED bulb?
MT7930, LM3445MM do bulb bulb, the effect is also ok.
Q:What are the requirements of the LED series inspection specification for bulb bulbs?
Dielectric strength: electrical endurance test (resistance test) followed by insulation resistance test. During testing, the following AC voltage is applied at the specified position 1min. Type HV (220~250V); 4000V (RMS), BV (100~120V); 2U (rated voltage) +1000v.
Q:How does the LED bulb look good or bad?
Power supply must be constant current power supply. This must, do not have that resistance. The constant current source resolution methods, there is no power is apart of a 8 foot IC, if not, no junk to, also not all the IC are good stuff, a famous lighting city have specialized quality of constant current power supply.
Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
4 and three is different. An incandescent lamp relies on heating the electrode wire to send out visible light. The energy-saving lamp releases the electrons by conducting the electrode wire, while the LED light is led by the diode.
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 how does the bulb return electricity?
maybe because Make the question clearWhat is the return current?
