Detail information:
- 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?
- The difference of power factor is large, and the resistance capacitance pressure drop is below 0.5 PF. Constant current and constant voltage drive PF over 0.9. The resistance drop pressure is really attractive, after all, the price is there. The average person doesn't understand the look.
- Q: Can the bulb's true life reach 30000~50000 by LED?
- LED life and quality, work current and many other factors. Life is calculated according to the half of the light
- 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: What are the types of LED bulb?
- According to the radiator shell to points, can be divided into plastic shell, aluminum radiator and ceramic shell, in general, the ceramic shell heat radiator is best, but the price is relatively expensive, the widespread use of aluminum shell, moderate price, good heat dissipation performance
- 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: How to identify Ic constant current LED bulb?
- The general user how to judge whether the bulb with constant current IC power supply, the general bulb is divided into three kinds, one is the RC driven RC drives are the most simple, because the cost is very low power small bulb and lamp using the scheme of small power LED bulb is often driven by RC, RC driving disadvantage is LED current with voltage fluctuation is changed, the brightness will change, so the resistance capacitance in the price is cheaper and less demanding bulb drive only, one with the IC LED driver, this there is also a constant current power supply, but the precision of constant current IC is not high, this power can only be used in the 220V voltage, the voltage fluctuation of relatively large area will affect the brightness of the LED lamp, and the stability of the power supply is relatively poor, life is better than Relatively short, easy to issue, this power supply is only a three - stage tube and two regulators circuit very...
- Q: Will the power of the LED bulb grow longer and longer? Why?
- Could you tell me the measurement method? - how about the side current and voltage? Or, whether direct measurement of active power under mains power supply?Also, can you tell me the circuit of LED bulb? DC power supply or AC power supply? Constant current module drive or RC current limiter? If the power supply is 12 volts low, is the resistor only current limiting?I feel something doesn't make sense......In one case, the longer the duration of the LED bulb, the greater the power:In some advanced LED bulb bulbs, an anti impact "slow start" circuit is added to the design, and a NTC (negative temperature coefficient) resistor is incorporated into the LED power supply circuit.Because of the larger resistance of NTC in cold state, the current of LED is smaller and the power is relatively small;With the use of electricity LED bulbs, NTC resistance temperature gradually increased, the resistance is reduced, the current of LED is also increased, so the power LED bulb also increases, temperature stability, until NTC resistance unchanged so far.
- Q: LED what does "A60" mean by bulb 60? And what does "MR16" mean?
- MR is a reflector that is represented by a plurality of reflector groups, and 16 represents the maximum outer diameter of 1/8*16*25.4=50
- Q: Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!
- Power supply must be constant current power supply. This must, do not have that resistance. The constant current source resolution methods, there is no power is apart of a 8 foot IC, if not, no junk to, also not all the IC are good stuff, a famous lighting city have specialized quality of constant current power supply.
- Q: Detailed description of LED bulb lamp
- Using high quality, high-power LED as a light source, energy saving, environmental protection, and high brightness, long life
