Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?

When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.

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: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: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:60W how many lumens and how many W LED bulb does incandescent bulb replace?

General household enough, if in 10 square meters of housing, installation of more than 10W LED lights, brightness is too good, if not the study, it is best not to.

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: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 does the LED bulb patch mean?

The patch is referring to the lamp is put up, refers to the non patch lamp is plugged in, the distinction is probably a stick is inserted.

Q:What are the types of LED bulb?

According to the interface, the LED bulb has GU10, E14, E27, E40 and so on.
