Detail information:
- 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's the cause of the noise during the aging of LED bulb bulbs?
- The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.
- Q: LED what kinds of screw bulbs are there?
- LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. With all the advantages of LED lamps: 1, energy saving, environmental protection; 2, long service life; 3, no stroboscopic, green.More energy-saving: LED lamp energy consumption is energy-saving lamp 1/4, incandescent lamp 1/10Long life: LED lamp life of up to 50 thousand hours, life expectancy is 5-10 times energy-saving lamps.More healthy: light evenly, no strobe, no glare, no UV and infrared.More environmentally friendly: no harmful substances such as mercury can be recycled to protect the green earth.Full color change: rich colors, vivid and delicate patterns and effects can be displayed.Installation convenience: simple installation, can replace incandescent lamp directly, maintenance cost is extremely low.
- Q: LED bulb bulbs, do you need 3C certification now?
- Light source class is impossible to do, only lamps and lanterns class can do. For example, flat lamp, ceiling lamp and so on...However, CQC voluntary certification can be done.
- Q: What are the characteristics of LED bulb?
- The service life is long, and the average life can reach 100 thousand hours.
- 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!
- Sandblasting can be transparent, light is not dazzling,But will still see the light...
- Q: Are there any differences between negative ion bulb and LED bulb?
- The negative ion belongs to bullshit type, the concept of things!
- 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: 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: Is there any flicker in the LED bulb?
- You're right. The strobe is either determined by the driver, the current changes, or the filter doesn't work well
