Q:What are the characteristics of LED bulb?

Energy saving research data show that, as LED is a cold light source, semiconductor lighting itself has no pollution to the environment, and compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of ordinary incandescent lamp and 1/2 of fluorescent lamp tube. If we replace 50% of our traditional lighting with LED at present, the amount of electricity we save every year will be equivalent to the sum of the total power generated by the Three Gorges power station, and the energy saving benefits will be considerable. LED, the lightning man at home, is pretty good

Q:Where can LED bulb be used?

LED bulb is generally civilian, living room, study room, kitchen, bathroom and so on

Q:What are the driving IC used in LED bulb?

Commonly used LED driver is based on the number of different W set, and now out of the drive program are quite a lot, according to customer requirements will also limit the number of different drivers IC.

Q:Will the power of the LED bulb grow longer and longer? Why?

The LED bulb does not become more powerful for extended periods of time.

Q:How did the trademark on the LED bulb go up?

Laser printing equipment is generally printed up, so that the ridge up color is not so deep, but also can not wipe off

Q:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?

There are several good LED ball bubble, which with aluminum cooling. Relatively new appearance.

Q:How to choose the bulb power?

If the public is not high, the quality requirements, and to control the price, you can choose non isolated, because it does not require isolation transformer, so the cost is relatively low, but the aluminum substrate voltage requirements is relatively high, otherwise there may be charged radiator, and still light outside is not very beautiful.

Q:What's the reason why LED bulb gets a lot of heat?

If the radiator is about the same size, it's not nice to touch the low temperature, because the heat accumulates in it and doesn't come out. The.LED lamp doesn't last long

Q:What does "A19" mean in LED A19 bulb?

I'm studying too! There's a problem for everyone to discuss

Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!

If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
