Detail information:
- Q: LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
- PDT flame retardant plastic, good heat dissipation, flame retardant effect, you see is not very good?
- 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: LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
- Delays generally do not exceed 1S. After rectification, the capacitor is charged to the IC VCC terminal through the starting resistance. When the starting voltage of the IC is reached, the output switch pulse signal of IC is LED, and the luminous work is realized.. That is to say, the greater the capacitance, the longer the delay.
- Q: What's the cause of the noise during the aging of LED bulb bulbs?
- The sound may be come from the power supply module components aging or faulty soldering and desoldering. LED long life, but may also be some problems.
- Q: What are the types of LED bulb?
- According to the power points, LED bulb has 1W, 3W, 5W, 7W, 9W, 12W, 15W and other power, customers can choose according to brightness requirements.
- 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: 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: Are there any differences between negative ion bulb and LED bulb?
- Negative ions should belong to traditional lighting technology, LED is the latest lighting technology
- Q: Is it possible to manually weld LED bulb bulbs?
- This is what you do very mature products, the most simple aging, is like this
- 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?
- Of course, the hotter the better, because for the same material, the hotter it is, the more heat the LED chips use, the less good the quality of the chips. The thermal characteristics of lamps is mainly to measure the junction temperature of LED Shenglai rather than the temperature of heat sink. Aluminum is commonly used in heat dissipation materials.
