Detail information:
- Q: What is the 15 Watt lumen of the LED bulb?
- Each brand has different bulb qualities, probably around 1W between 60-85LM/W.
- Q: In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate
- The lamp is normal body temperature measurement temperature lamp, lamp heat sink temperature is the key, if the heat do good, heat sink temperature is close to the junction temperature, but the temperature are generally measured lamp pin temperature, plus a rise coefficient estimation of heat sink temperature, so as to estimate. The temperature of the lamp. The temperature of the aluminum substrate and the heat sink is relatively surface, and the superficial and relatively useful temperature depends on the junction temperature, which is related to the life of the LED. So the temperature near the pin or heat sink is more realistic.
- Q: Led the bulb is flashing. What's wrong with it? How do you fix it?
- There is a drive power failure, and if you do not electronic repair ah, it is recommended to return directly to another driver, generally have 1 years warranty period
- Q: What's the reason for the LED bulb strobe?
- If this resonant characteristic causes the input current to fall below the TRIAC sustaining current, the TRIAC will turn off. After a short delay, the TRIAC usually switches on and fires the same resonance. In the 1.5 cycle of the input power waveform, this series of events may be repeated several times to form visible LED flashes. To cope with this problem, a key requirement of TRIAC dimming is that the input capacitance of the EMI filter is very low and that the capacitor is decoupled through the TRIAC and the winding impedance. According to the formula, if the capacitance of the dimming module is reduced, the resistance of the resonant circuit can be increased, and the oscillation is suppressed in principle, and the desired circuit work is resumed.
- Q: I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
- It's possible to assemble your own bulb. The power used in the bulb is too large. It causes the gold wire to burn
- Q: What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!
- Can reach 90% of the light, can not see the inside of the lamp
- 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: Choose which light bulb LED bulb is the healthiest
- The two said warm light, power, color temperature and so on have little to do with health
- Q: How did the trademark on the LED bulb go up?
- And the use of silk screen or pad printing, this is the need for the corresponding ink, this solution with a dedicated solution can be dissolved, and also have some prominent hand touch.
- 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.
