Q:Where can LED bulb be used?

The surface of the lamp body is sprayed with high quality heat radiation paint, that is, the heat dissipation efficiency is ensured, and the appearance is elegant, and the utility model provides better guarantee for the low temperature work of the product.

Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!

A light source, two power supply, three workmanship.Online shopping, I strongly suggest that you buy some reliable.

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?

Now the market LED lamps quality uneven. LED lamps need constant current and constant voltage drive to be durable. The cheap 3W LED plastic bulb power supply is only the drive of the resistance capacitance pressure drop. Drive rank: 1. constant current and constant voltage drive. 2. constant current non constant voltage drive. 3. constant pressure and no current drive. 4. resistance capacitance pressure drop drive (resistance capacitance voltage drop is the worst and cost is the cheapest)

Q:What's the reason for the LED bulb strobe?

Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.

Q:LED thread specifications for bulb bulbs?

Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!

Q:Are there any differences between negative ion bulb and LED bulb?

LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.

Q:Led the bulb is flashing. What's wrong with it? How do you fix it?

The general power supply too much heat to stimulate the overheating protection function itself with the power supply, power supply is a protection device, when the heat is too large, may cause it has an adverse effect on power and light, power will take the initiative to make the lamp power, rest, fully dissipated heat later. Bright. 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 material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!

Can reach 90% of the light, can not see the inside of the lamp

Q:LED how does the bulb return electricity?

maybe because Make the question clearWhat is the return current?

Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb

The light produced by the three is different. From the lighting point of view, incandescent light can generally emit yellow light, and energy-saving lamps can not only send yellow light, but also white light, etc., and LED lights can be issued according to the needs of a variety of light, decorative lighting is very good.
