- Q: LED bulb PC, will the white cover affect the color temperature of the finished lamp?
- The chip may damp, no air humidity warehouse management process; or the chip in the assembly process by foreign influence, the lampshade is removed, and then measured once in the color of the aluminum plate radiator
- Q: What's the reason why LED bulb gets a lot of heat?
- If the radiator has a large radiating area, the temperature is low
- Q: LED bulb with what type of LED beads?
- Of course, the more high-end heat better use EMC3030 lamp, EMC2835 lamp and so on, please consult your supplier
- Q: Seeking the production process of LED bulb... Thanks
- 10 points, Baidu wants to be a LED engineer. LZ is a real budget man
- Q: LED what kinds of screw bulbs are there?
- Ordinary bulb is the most common, is a metal electrode which is threaded, so it requires that one electrode when installing the socket contact thread to pick the zero line, the middle dot electrode lamp power. Otherwise, an electric shock occurs when an accidental contact with the exposed metal. Because of this symmetrical way, the bulb can be threaded to fit the socket.
- Q: In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate
- The lamp is normal body temperature measurement temperature lamp, lamp heat sink temperature is the key, if the heat do good, heat sink temperature is close to the junction temperature, but the temperature are generally measured lamp pin temperature, plus a rise coefficient estimation of heat sink temperature, so as to estimate. The temperature of the lamp. The temperature of the aluminum substrate and the heat sink is relatively surface, and the superficial and relatively useful temperature depends on the junction temperature, which is related to the life of the LED. So the temperature near the pin or heat sink is more realistic.
- 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: 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?
- Q: How to identify Ic constant current LED bulb?
- Another is to destroy the bulb and see the power inside the bulb. Not a constant current power supply, only some capacitors, diodes, resistors, and the like. The constant current drive, in addition to the diode electrolytic capacitor, there is a 6 foot IC and a triode, there is a high frequency isolation transformer. To make it clear, you can take a look at it.
- Q: What brand of LED bulb is good in quality?
- See shape. Incandescent bulbs are usually pear shaped, so the bulb should be pear shaped. That's easy to do. But incandescent lamps are all glass products, and because LED requires heat radiation, aluminum alloys are usually used as housings, because of their low cost, easy processing, and good thermal conductivity. The size of the aluminum shell determines the heat dissipation and also determines the life span.
