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 standard is the body temperature of the LED lamp. With a multimeter probe is placed in the LED lamp bulb angle can be measured temperature. Generally -20~80 degrees centigrade

Q:Is there any flicker in the LED bulb?

First of all, I want to know what kind of LED bulb you bought. Is the LED light source small power or high power?Now on the market LED products, copycat too much, but also a lot of difference between quality and price, because the power output strobe filtering problem. Because the lowest requirements so the power design is very simple, such as shell is small power ball type PVC foam, with isolated power so far I saw several, but the price is very high, and most with the rectifier bridge, several rectifier diode, a capacitor, resistor several complete, low prices. High power type bulb is similar, but the power will be much better, is the constant current source in the output current of the filter is also doing well, there the strobe is low! Finally, the stroboscopic problem is on the power supply, and the power point difference is higher than one or two!!

Q:Why can't the voice switch control the time of the LED bulb?

Originally white silk lamp, later replaced by LED bulb, with a light activated switch control, replaced by LED bulb, the lamp does not extinguish for 30 seconds

Q:Where can LED bulb be used?

The surface of the lamp body is sprayed with high quality heat radiation paint, that is, the heat dissipation efficiency is ensured, and the appearance is elegant, and the utility model provides better guarantee for the low temperature work of the product.

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's the difference between a glass cap for a bulb and a PC hood?

Surface hardnessPC biggest weakness is surface hardness, PC although resistance to impact, smashing not broken, but after all is plastic, surface hardness value is not high, easy to scratch, easy to scratch.While glass is easy to break, not shock, but the surface hardness is high, it is not easy to scratch the surface!Other weather resistant, temperature resistant supplementsPC cover, in processing, plus UV agent

Q:LED how does the bulb return electricity?

A 0 ohm resistor with a large point on the negative electrode

Q:LED what does "A60" mean by bulb 60? And what does "MR16" mean?

MR is a reflector that is represented by a plurality of reflector groups, and 16 represents the maximum outer diameter of 1/8*16*25.4=50

Q:What are the requirements of the LED series inspection specification for bulb bulbs?

The temperature rise of the finished lamp is not more than 120K. The temperature rise is equivalent to the maximum value of 60W incandescent lamp.

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).
