Q:LED can the bulb be used in the bathroom?
Yes, the bulb may is waterproof and dustproof with protection
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: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:Will the power of the LED bulb grow longer and longer? Why?
In general, LED energy-saving lamps (including LED bulb bulbs) use a constant current drive that does not change the magnitude of the current with time or temperature, so it does not become more powerful as it grows for longer periods of time.On the other hand, if because of long time use leads to LED lamp temperature rise, according to the electrical properties of semiconductor, the PN junction voltage will also decreases with increasing temperature. Then, when the current is constant, a drop in the voltage drop means a decrease in power consumption, although the reduction is very small.
Q:Ordinary lamp LED bulb can?
Absolutely, without any effect. It can be directly across to look at the opening of several inches.
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:Is it possible to manually weld LED bulb bulbs?
If you can guarantee that you can add thermal grease just fill the gap without obstructing the normal contact, it is useful, but this process is very difficult for you to do, and the theory can improve the thermal efficiency of thermal grease, but actually you are not up to the process it is possible to reduce the thermal efficiency, you added more is to seek psychological comfort, you can on the heating plate welding of light, with one side of the thermal grease solder, such thermal effect is better
Q:LED bulb PC, will the white cover affect the color temperature of the finished lamp?
In the integration sphere measurement, there is no standard lamp to proofread, or something else in the interior affects the measurement result, for example, the color of the lamp body itself will affect the color temperature more or less. Single color beads, chip on the aluminum base?
Q:What does "A19" mean in LED A19 bulb?
A stands for bubble type, A hemisphere bubble19 the numbers in the back indicate the size of the bulb (mm in diameter)On the market LED bulb generally has: hemisphere bubble lamp, A15, A17, A50, A60Global bubble G45, G55, G80, G120 and so on
Q:How to identify Ic constant current LED bulb?
Let me tell you what. If the bulb is not damaged, the regulator needs a regulator to lower its voltage and see if the bulb's brightness is dark. If it follows, it is not a constant current source, but a blocking capacitor. If the voltage is greatly reduced, the brightness change is not constant, that is, the constant current source bulb (because the constant current source lamp can change between 80V--260V, the voltage is normal, and the output is constant).
