Detail information:
- Q: LED bulb with what type of LED beads?
- The LED bulb is mainly white and warm white two colors are white, the temperature is generally 6000-6500K color, the color of the sun light at noonWarm white temperature is 2700-3000K, yellow, similar to the sunset color temperature.
- Q: How to choose the bulb power?
- If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.
- Q: Seeking the production process of LED bulb... Thanks
- First of all, of course, the preparation of materials, the specific operation of the lamp to practice, each lamp has different methods of assembly, there are different work instructions. Only through practice can we write good and practical processes. Figure is a flow chart of MR16 assembly.
- Q: What's the cause of the noise during the aging of LED bulb bulbs?
- This should be the power problem. It's easy to make a noise because there are so many parts of the power supply.
- Q: Led the bulb is flashing. What's wrong with it? How do you fix it?
- The driving power inside is broken. If there is basic electronic knowledge, replace the inner capacitor. Most probably the electrolytic capacitor is broken.However, the cost of the bulb products is relatively low, and the cost of the repair is greater than the cost of the change.
- Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
- The meter usually doesn't turn because the current is too small to drive the meter (Mechanical), of course, the electronic meter also depends on the sensitivity. I don't think so. At least I used to do LED (light power about 0.5W it) is equivalent to 3W incandescent lamp brightness around. The meter does not rotate when it is shining normally.
- 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: 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?
- 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.
- Q: Secret LED bulb bubble price difference why so big?
- Remember, cheap, no good goods, the market price of less than 15 yuan bulb said that their quality is not credible.
