Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?: It is best not to direct contact with glue, glue because the thermal conductivity of aluminum than a lot of difference, even a thin layer will reduce the heat out of the speed of the screw can be used to aluminum plate and aluminum fastening together, the contact surface is smooth, when necessary, can use some conductive silicone grease amount

Q:Will the power of the LED bulb grow longer and longer? Why?: Could you tell me the measurement method? - how about the side current and voltage? Or, whether direct measurement of active power under mains power supply?Also, can you tell me the circuit of LED bulb? DC power supply or AC power supply? Constant current module drive or RC current limiter? If the power supply is 12 volts low, is the resistor only current limiting?I feel something doesn't make sense......In one case, the longer the duration of the LED bulb, the greater the power:In some advanced LED bulb bulbs, an anti impact "slow start" circuit is added to the design, and a NTC (negative temperature coefficient) resistor is incorporated into the LED power supply circuit.Because of the larger resistance of NTC in cold state, the current of LED is smaller and the power is relatively small;With the use of electricity LED bulbs, NTC resistance temperature gradually increased, the resistance is reduced, the current of LED is also increased, so the power LED bulb also increases, temperature stability, until NTC resistance unchanged so far.

Q:Led what's the flash of the bulb?: There are several cases of flashing lights:There is one to three flashes when the switch is switched off. This is due to an incomplete discharge of the electrolyte in the power supply.The power supply is flashing fast. This is the quality of the power supply problems, there are many specific reasons.It is found that the design of the power supply is related to the structural design of the lamp due to the insufficient margin of the power supply and the increase of temperature!The general power supply too much heat to stimulate the overheating protection function itself with the power supply, power supply is a protection device, when the heat is too large, may cause it has an adverse effect on power and light, power will take the initiative to make the lamp power, rest, fully dissipated heat later. Bright.

Q:What is the 15 Watt lumen of the LED bulb?: LM, refers to a candle (CD, Candela Candela, unit of luminous intensity, the equivalent of an ordinary candle light intensity) in a solid angle corresponding to the spherical cone ball (1 square meters of the unit sphere radius of 1 meters on the representative point of view, the corresponding section in the center angle of about 65 degrees the total emission flux) on the.

Q:What advantages does LED bulb replace energy saving lamp?: The response time is fast, the energy saving lamp is millisecond, and the LED light is nanosecond

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:LED bulb bulbs, do you need 3C certification now?: Light source class is impossible to do, only lamps and lanterns class can do. For example, flat lamp, ceiling lamp and so on...However, CQC voluntary certification can be done.

Q:How to choose the bulb power?: The basic types of bulb power are divided into two types: isolated and non isolated

Q:What's the cause of the noise during the aging of LED bulb bulbs?: The sound may be come from the power supply module components aging or faulty soldering and desoldering. LED long life, but may also be some problems.

Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?: Now the market LED lamps quality uneven. LED lamps need constant current and constant voltage drive to be durable. The cheap 3W LED plastic bulb power supply is only the drive of the resistance capacitance pressure drop. Drive rank: 1. constant current and constant voltage drive. 2. constant current non constant voltage drive. 3. constant pressure and no current drive. 4. resistance capacitance pressure drop drive (resistance capacitance voltage drop is the worst and cost is the cheapest)
