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: The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb: 5, the three have different service life. The service life of incandescent lamp is in 1000 hours or so, the service life of energy-saving lamp is in 6000-8000 hours, and the service life of LED lamp can reach more than 30 thousand hours.

Q: How to choose the bulb power?: LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. Have the advantage of all LED lamps and lanterns:1, energy saving, environmental protection;2, long service life;3 、 no strobe, green.

Q: LED how does the bulb return electricity?: A 0 ohm resistor with a large point on the negative electrode

Q: What are the requirements of the LED series inspection specification for bulb bulbs?: Insulation resistance: the lamp should not be placed for 48 hours in the damp box with relative humidity of hours. The air temperature in the box shall be controlled at any value between 20~30 degrees centigrade, and the temperature difference is within 1 degrees. The insulation resistance shall be measured in the wet box. Now the DC voltage on the lamp is about 500V. After 1min, the insulation resistance test will begin. The insulation resistance between the lamp holder, the current carrying metal parts and the accessible lamp parts shall be no less than 4M ohms.

Q: What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!: Sandblasting can be transparent, light is not dazzling,But will still see the light...

Q: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!: If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem

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: Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!: You are not the light source, in addition to a treasure bully ordinary consumers can't tell the difference between good and poor light source, all blow themselves jingyuan. I think you can see for yourself, not necessarily expensive or cheap but wafer, it certainly can not be said. Big power of a simple 1W bar, poor beads 1-3 cents, the wafer will be 1.3-2 dollars. There are several tiles, and how much does it cost?.

Q: Want to find common features, unified purchase accessories repair!: 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
