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:How to identify Ic constant current LED bulb?
Look at the power supply, there are a few simple electronic and capacitive circuit board, it is not constant flow, cross flow is larger, so understand? Cross flow IC, that is, the meaning of intelligent voltage regulator, so that the LED is not easy, bad capacitor driven LED is relatively easy to damage, easily breakdown, and power consumption than the cross flow
Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
General household enough, if in 10 square meters of housing, installation of more than 10W LED lights, brightness is too good, if not the study, it is best not to.
Q:Will the power of the LED bulb grow longer and longer? Why?
Voltage problems, as well as unstable factors.Long time no change, should
Q:What does the LED bulb patch mean?
The patch is referring to the lamp is put up, refers to the non patch lamp is plugged in, the distinction is probably a stick is inserted.
Q:What are the driving IC used in LED bulb?
The analysis report shows that nearly three years, the domestic market share of LED lamps will increase from 5% to about 20%-30% can be seen, LED is now the need to walk into the homes of ordinary people, so we need to control the cost, cost is the main driving power LED lamp and a shell, a power driven material faster BOM province can let the promotion of LED. As the LED lamp has the characteristics of energy saving and environmental protection, the state has also subsidized the product accordingly.
Q:Can the bulb's true life reach 30000~50000 by LED?
The theory of the life of LED is one hundred thousand hours, this is not true; but the LED life is far less than one hundred thousand hours, only ten thousand hours, which is currently the most industrialized production of long life; because the quality of the LED part of the core - epitaxial wafer has not reached the ideal state, there are many problems to be solved, such as reducing the dislocation the density of epitaxial film, high quality P GaN preparation etc.
Q:LED how to classify bulb bulbs?See some LED bubble bulb specifications are written in A60, A45, and some are written G60, G45, I do not know, in addition to the maximum diameter of the same, what is the difference between the meaning of A and G?In addition, how can the whole LED bulb be classified, only by the maximum diameter, or with other classifications?,
Small power white and colored light shape is the same, is not good. The addition of a small power LED Corn Cob, egg shape, tail lamp, candle lamp from the appearance of good resolution. A or G prefix is marked outsideNo other special significance
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!
The milk white paint can't see light, but the transmittance is only eighty percent a few. At present, the market has not seen in line with the economic benefits of such LED ball bubble glass cover, can reach ninety percent transmittance. If any brother finds it, please let us know. We also want it very much. Oh, thank you.
Q:LED can the bulb be used in the bathroom?
of couse Yes, but LED kitchen and toilet light is recommended
