Q:Is it possible to manually weld LED bulb bulbs?
You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off
Q:Who knows where the broken LED bulb is?
Common problems, a lamp is broken, the heat is not good cause, most likely it is a bad driver. As for the aluminum substrate, it should not be bad
Q:Why can't the voice switch control the time of the LED bulb?
Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.
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: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.
Q:What are the types of LED bulb?
power LED bulb is the traditional incandescent lamp 1/10, half of the power of the energy-saving lamp, high efficiency and energy saving is the best
Q:What does "A19" mean in LED A19 bulb?
A19 is the European A60: represents the outer diameter 60mm=19/8*25.4=60.325mm, such as the diameter of the A19 bulb. "D=19*1/8", multiplied by 25.4, is the diameter of the bulb in mm units. The source of this formula is the same as the T8 tube: "X" in Tx means that the diameter of the tube is x times 1/8 inches, so the diameter of T8 is 1/8 inches x 8=1 inches, or 25.4mm
Q:Are there any differences between negative ion bulb and LED bulb?
The brightness of LED anion bulb of each LED have good consistency, high color purity, light stability. 1W power, ultra low energy consumption. A variety of light colors are available for you to create a dream like color space. Built in negative ion generator, each cubic centimeter produces 3000000 negative ions that allow you to have a healthy air environment while you own light. Negative ions can effectively remove formaldehyde, benzene, toluene, ammonia, acetone, carbon monoxide, sulfur dioxide and other toxic gases, for your breathing health increased by a solid line of defense.
Q:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?
LED bulb lamp, are driven by a power of the ordinary small beads, driving is very simple only rectification, filtering, limiting the number of components is another large power SMD beads, this drive is more troublesome, SMT SMD components, and double plate, both have the element.
Q:LED how does the bulb return electricity?
A 0 ohm resistor with a large point on the negative electrode
