Q:LED can the bulb be used in the bathroom?
From a long-term perspective is not enough, you can choose a lamp are closed, such as ceiling lamps what, now have special indoor lamps, but you must not use ordinary lamps, because LED lights to the heat at the edge of the open slot or empty, easy water.
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.
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's the reason for the LED bulb strobe?
8W offline LED driver GreenPoint reference design with solid state lighting standard energy star "as an example, the sine wave regulator side flyback power conversion does not provide constant energy to the primary bias, dynamic self supply (DSS) circuit can be activated and the light induced flicker. To avoid this problem, it is necessary to allow primary bias to be discharged at each half cycle, and accordingly, the values of the capacitance and resistance that constitute the bias circuit need to be appropriately chosen.
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:Is it possible to manually weld LED bulb bulbs?
As long as the welding technology clearance is possible or OK
Q:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?
LED bulb: directly driven by not using AC-LED light source, light effect of the whole lamp life (compared with driving security; some) integrated LED relative heat transfer to the high requirements, high cost, simple assembly, do a single power source in low cost, high light efficiency.
Q:What advantages does LED bulb replace energy saving lamp?
LED lamp structure is strong, green environmental protection, not easy to destroy, long life (generally 5 years is not a problem), this is energy-saving lamps can not be compared
Q:LED thread specifications for bulb bulbs?
Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!
Q:LED bulb with what type of LED beads?
Of course, the more high-end heat better use EMC3030 lamp, EMC2835 lamp and so on, please consult your supplier
