Q:What are the characteristics of LED bulb?

Less power consumption, a 5 Watt LED bulb, equivalent to 40 watts of ordinary incandescent.

Q:Secret LED bulb bubble price difference why so big?

Power Supply。 Good quality will be equipped with power supply, usually in the lamp cavity. And low prices are put on the lamp board with several capacitive resistance to deal with

Q:LED can the bulb be used in the bathroom?

Kitchen lighting bathroom and kitchen with special waterproof, but the working voltage of LED is low, LED lamp is also a big problem in the use of a water vapor environment, general heat sink should be no problem, is such as the use of aluminum shell, like plastic shell can not, because they on the cold and hot air convection cooling, casing is provided with a hole for air inside and outside the exchange, will put into the high-pressure part of water vapor driven, it will affect the service life.

Q:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?

Depending on your application and cost, there's no way to say which is absolutely good;If the occasion is appropriate and the cost is not urgent, buy a drive.

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: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: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 what is the glue between the aluminum base of the bulb and the cooling aluminum?

Heat conductive adhesive is best.Heat conductive adhesive, also known as thermal conductive silica gel. Organic silica gel as the main body, adding fillers, thermal conductive materials and other polymer materials, mixed by silica gel, has better thermal conductivity, electrical insulation performance, widely used in electronic components. Also known as: thermal silica, silicone rubber, silicone heat, thermal conductivity of silicone. The accelerator is used to solidify a transformer, transistor, and other heating elements onto a printed circuit board assembly or radiator

Q:LED how does the bulb return electricity?

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

Q:What does "A19" mean in LED A19 bulb?

I'm studying too! There's a problem for everyone to discuss
