Q: Where can LED bulb be used?: LED bulb is a new type of energy saving lamp to replace traditional incandescent bulb. The traditional incandescent lamp (lamp) of high energy consumption, short service life, in the global resource environment, has been gradually by governments to ban the production, instead is the product of electronic energy-saving lamp, electronic energy-saving lamp while improving the energy saving effect, but because of heavy metals using a lot of pollution of the environment, trend against the environment protection.

Q: What are the driving IC used in LED bulb?: Commonly used LED driver is based on the number of different W set, and now out of the drive program are quite a lot, according to customer requirements will also limit the number of different drivers IC.

Q: What are the types of LED bulb?: According to the interface, the LED bulb has GU10, E14, E27, E40 and so on.

Q: LED bulb w can replace 40W incandescent lamp: D lamp lumen value is ordinary incandescent lamp about 3 times, but LED ball bubble mask transmittance should be based on material, can use 10W or so LED acrylic mask ball bubble instead. Because I received a similar customer complaint, 7W's LED light bulb was replaced with an 20W energy-saving lamp, which was not bright enough.

Q: What advantages does LED bulb replace energy saving lamp?: More importantly, 3W's LED light can replace 15W's energy saving light

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: Detailed description of LED bulb lamp: High purity aluminum reflector, radiator, acrylic glass cover, high power LED light source, high efficiency imported constant current source. 2. The bulb has high luminous efficiency and good environmental protection performance. It does not contain harmful substances, has no pollution to the environment, does not have infrared rays and ultraviolet rays, and avoids harm to the human body, and belongs to the green lighting products. 3, PC light shield, optional transparent or matte, to prevent glare and effectively protect the LED lamp, unique optical design, light distribution. 4, good color, to show a true color of things, a variety of color options, to meet the different needs of the environment, eliminating the traditional lamp color temperature depression caused by excessively high or low, the Department of visual comfort, improve the working efficiency of workers. 5, the bulb of the spiral points E27 and E40, easy installation, alternative to the traditional 65W125W energy-saving lamps. 6, the bulb is made of high quality aluminum alloy for shell production, good corrosion resistance, long service life, energy-saving effect is obvious. 7, bulb 30W installation height of 3-4 meters, 50W installation height of 5-6 meters.

Q: LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?: The cost is too high, the latter is better than the former, with long service life, there is a need bulb welcome to Taobao fry and sales of professional manufacturers of high power LED lighting lamp.

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
