- Q: LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?
- There are several good LED ball bubble, which with aluminum cooling. Relatively new appearance.
- 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: 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: Led the bulb is flashing. What's wrong with it? How do you fix it?
- 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!
- Q: LED bulb w can replace 40W incandescent lamp
- I am engaged in the LED drive industry, not very professional, and I hope to help you.About brightness and energy saving comparison,1W LED=3W CFL (energy saving lamp) =15W incandescent lamp3W LED=8W CFL (energy saving lamp) =25W incandescent lamp4W LED=11W CFL (energy saving lamp) =40W incandescent lamp8W LED=15W CFL (energy saving lamp) =75W incandescent lamp12W LED=20W CFL (energy saving lamp) =100W incandescent lampBecause the company uses the light quality is not a reason, so this is not absolute.
- 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 identify Ic constant current LED bulb?
- Look at the power supply, there are a few simple electronic and capacitive circuit board, it is not constant flow, cross flow is larger, so understand? Cross flow IC, that is, the meaning of intelligent voltage regulator, so that the LED is not easy, bad capacitor driven LED is relatively easy to damage, easily breakdown, and power consumption than the cross flow
- Q: What brand of LED bulb is good in quality?
- What brand of LED bulb is good? LED bulb has replaced the ordinary fluorescent lamp and incandescent lamp gradually, with the market demand is more and more big, and the production of the LED lamp threshold is very low, so a lot of small family workshop also began assembling production of LED lamps, the technical content is low, without testing and certification of products, also began to circulate on the market.
- Q: LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
- LED bulb is broken. The luminous patch is not bad. It can be made into USB lamp.LED bulb is usually a series of LED series, and then parallel, generally about 12V.Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated.Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current.Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light to normal brightness, or it may damage the USB interface. It is better to use the USB charger interface.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.
- Q: How did the trademark on the LED bulb go up?
- Laser printing equipment is generally printed up, so that the ridge up color is not so deep, but also can not wipe off
