FAQ

Ordinary lamp LED bulb can?

It should be clear, your point is before the lamp lights inside what, from the rectifier? LED bulb is mostly with drive, if there is no self rectifier lamp light, the best is the bulb is directly connected to the E27/E14/B22 lamp, LED lamp or light source has a good energy saving effect, mercury free lead-free, no stroboscopic, energy than traditional fluorescent lamp 80%

Want to find common features, unified purchase accessories repair!

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

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

What brand of LED bulb is good in quality?

What brand of LED bulb is good? LED bulb has replaced the ordinary fluorescent lamp and incandescent lamp gradually, with the market demand is more and more big, and the production of the LED lamp threshold is very low, so a lot of small family workshop also began assembling production of LED lamps, the technical content is low, without testing and certification of products, also began to circulate on the market.

What are the characteristics of LED bulb?

LED bulb advantages: energy saving: the same brightness, power consumption for ordinary energy-saving lamps 1/4. Environmental protection: no harmful substances such as mercury, no pollution to the environment. (experts point out that mercury contained in a fluorescent energy-saving lamp can contaminate 180 tons of water sources). Economy: as a result of electricity saving, electricity costs can be reduced, and the cost of the lamps can be recovered for one and a half years. A family can save tens of thousands of yuan a month. Low carbon: saving electricity is equivalent to reducing carbon emissions. Long life: LED lamp life of 50 thousand hours, six hours a day, that is, 20 years of life. The price depends on how many watts you need, and the price varies with the wattage. Now the family uses "lightning man" led, very good, the price, quality, those are good, you can go and see. Hope to help you.

LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!

Power supply has noise, it is the design of transformer, winding, the design of switch power supply.. Engineering reference..

LED how does the bulb return electricity?

A 0 ohm resistor with a large point on the negative electrode

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

If the radiator has a large radiating area, the temperature is low
