Factory
- Q:Detailed description of LED bulb lamp
- A bulb can be said to be the highest cost of the driver, not the driver, light is not bright. And for the quality of a ball bubble
- Q:Ordinary lamp LED bulb can?
- Yes, just buy a high voltage LED light bulb. Contact me. I'll send it to you from the factory
- Q:LED bulb bulbs, do you need 3C certification now?
- No, this is a light source, not a lamp. It can only be CQC voluntary certification
- Q:Want to find common features, unified purchase accessories repair!
- The most common problem is that 1, the drive power is broken 2, the light source due to excessive or excessive flow leading to necrosis
- Q:What are the characteristics of LED bulb?
- Energy saving research data show that, as LED is a cold light source, semiconductor lighting itself has no pollution to the environment, and compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of ordinary incandescent lamp and 1/2 of fluorescent lamp tube. If we replace 50% of our traditional lighting with LED at present, the amount of electricity we save every year will be equivalent to the sum of the total power generated by the Three Gorges power station, and the energy saving benefits will be considerable. LED, the lightning man at home, is pretty good
- 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: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:Choose which light bulb LED bulb is the healthiest
- Choose LED lights, first, no strobe, strobe damage to the eyes, second color index to be high, true and clear. For the quality, choose to heat better, high power factor, so that the relative power of the lamp, power saving, durable
- Q:Are there any differences between negative ion bulb and LED bulb?
- LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.
- Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
- Cannot connect directly. LED bulb is usually a series of LED series, and then parallel, generally about 12V. Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.
