- 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: 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: 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: The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
- 5, the three have different service life. The service life of incandescent lamp is in 1000 hours or so, the service life of energy-saving lamp is in 6000-8000 hours, and the service life of LED lamp can reach more than 30 thousand hours.
- 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: How does the LED bulb go with the power?
- Generally we use the LED lights, 1W, 2W, 3W, 12W, and so on, the factory has been set in advance, directly connected to the 220 volt power supply can be, and do not need to be so complicated.
- Q: LED bulb w can replace 40W incandescent lamp
- The standard of luminous flux according to the luminaire is lumen (LM). Incandescent lamps are w 11-12lm per 40w=440-480lm
- Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
- If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
- Q: Want to find common features, unified purchase accessories repair!
- Common problems, a lamp is broken, the heat is not good cause, most likely it is a bad driver. As for the aluminum substrate, it should not be bad
- Q: Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?
- With the temperature of the heat sink to judge a lamp is not easy, the domestic aluminum radiator are generally more, for T8T5 will have to see the size of the whole lamp power, the simplest is to look at the weight, the relative materials generally heavier will be better.
