Q:What's the reason for the LED bulb strobe?
8W offline LED driver GreenPoint reference design with solid state lighting standard energy star "as an example, the sine wave regulator side flyback power conversion does not provide constant energy to the primary bias, dynamic self supply (DSS) circuit can be activated and the light induced flicker. To avoid this problem, it is necessary to allow primary bias to be discharged at each half cycle, and accordingly, the values of the capacitance and resistance that constitute the bias circuit need to be appropriately chosen.
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:Will the power of the LED bulb grow longer and longer? Why?
In general, LED energy-saving lamps (including LED bulb bulbs) use a constant current drive that does not change the magnitude of the current with time or temperature, so it does not become more powerful as it grows for longer periods of time.On the other hand, if because of long time use leads to LED lamp temperature rise, according to the electrical properties of semiconductor, the PN junction voltage will also decreases with increasing temperature. Then, when the current is constant, a drop in the voltage drop means a decrease in power consumption, although the reduction is very small.
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 requirements of the LED series inspection specification for bulb bulbs?
Insulation resistance: the lamp should not be placed for 48 hours in the damp box with relative humidity of hours. The air temperature in the box shall be controlled at any value between 20~30 degrees centigrade, and the temperature difference is within 1 degrees. The insulation resistance shall be measured in the wet box. Now the DC voltage on the lamp is about 500V. After 1min, the insulation resistance test will begin. The insulation resistance between the lamp holder, the current carrying metal parts and the accessible lamp parts shall be no less than 4M ohms.
Q:What does "A19" mean in LED A19 bulb?
I'm studying too! There's a problem for everyone to discuss
Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
It is best not to direct contact with glue, glue because the thermal conductivity of aluminum than a lot of difference, even a thin layer will reduce the heat out of the speed of the screw can be used to aluminum plate and aluminum fastening together, the contact surface is smooth, when necessary, can use some conductive silicone grease amount
Q:LED can the bulb be used in the bathroom?
Kitchen lighting bathroom and kitchen with special waterproof, but the working voltage of LED is low, LED lamp is also a big problem in the use of a water vapor environment, general heat sink should be no problem, is such as the use of aluminum shell, like plastic shell can not, because they on the cold and hot air convection cooling, casing is provided with a hole for air inside and outside the exchange, will put into the high-pressure part of water vapor driven, it will affect the service life.
Q:Where can LED bulb be used?
Led bulb is now commonly used in civil products, is the most is a spherical bulb
Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
Have you used it or haven't you bought it yet?
