Q:LED bulb with what type of LED beads?

There are many LED bulbs with LED lamp types, different lighting manufacturers will adopt different LED models, at present, most of the 2835, 5730 beads, beads are 0.5W-1W LED beads, specific type: PL-P2835DW-C8-R3-C2/ PL-P5730EDW-C8-R3-C2

Q:What are the characteristics of LED bulb?

LED bulb advantages: energy saving: the same brightness, power consumption for ordinary energy-saving lamps 1/4. Environmental protection: no harmful substances such as mercury, no pollution to the environment. (experts point out that mercury contained in a fluorescent energy-saving lamp can contaminate 180 tons of water sources). Economy: as a result of electricity saving, electricity costs can be reduced, and the cost of the lamps can be recovered for one and a half years. A family can save tens of thousands of yuan a month. Low carbon: saving electricity is equivalent to reducing carbon emissions. Long life: LED lamp life of 50 thousand hours, six hours a day, that is, 20 years of life. The price depends on how many watts you need, and the price varies with the wattage. Now the family uses "lightning man" led, very good, the price, quality, those are good, you can go and see. Hope to help you.

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:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?

Cannot connect directly. 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.

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?

As long as the welding technology clearance is possible or OK

Q:LED how does the bulb return electricity?

maybe because Make the question clearWhat is the return current?

Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb

The light produced by the three is different. From the lighting point of view, incandescent light can generally emit yellow light, and energy-saving lamps can not only send yellow light, but also white light, etc., and LED lights can be issued according to the needs of a variety of light, decorative lighting is very good.

Q:How to choose the bulb power?

If it is household, choose the separation side, because the separation type is relatively safe, easier to pass through safety regulations, but the cost is relatively high, but suitable for home use.

Q:What's the reason why LED bulb gets a lot of heat?

If the radiator is about the same size, it's not nice to touch the low temperature, because the heat accumulates in it and doesn't come out. The.LED lamp doesn't last long
