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:Secret LED bulb bubble price difference why so big?

Lamp beads。 I also do with Samsung bulb, bulb, lamp light cost more than others product price;

Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!

See brightness, whether the luminous uniformity, the back of the heat is good?

Q:Seeking the production process of LED bulb... Thanks

10 points, Baidu wants to be a LED engineer. LZ is a real budget man

Q:Ordinary lamp LED bulb can?

No problem, the heating LED bulb is mainly aluminum shell above on the lamp body, a lamp holder will not affect the interface, and the heating temperature does not exceed 60 degrees, and the plastic cap interface at least 160 degrees above the melting point, so is not affected on the lamp interface, you can rest assured that use

Q:LED thread specifications for bulb bulbs?

Specifications also include bulb, E27, E26, B22, E14, G10, E40;E27 specifications are in the majority.

Q:Led what's the flash of the bulb?

I don't know how you flashed this light. Did you flash or turn off the light before you left it?. If the lights are off, you should ask the electrician if the line on the switch is connected or not. If the switch is connected to the negative line, it will flash. If it is open after the flash, mostly driving power problems

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!

The milk white paint can't see light, but the transmittance is only eighty percent a few. At present, the market has not seen in line with the economic benefits of such LED ball bubble glass cover, can reach ninety percent transmittance. If any brother finds it, please let us know. We also want it very much. Oh, thank you.

Q:What's the difference between a glass cap for a bulb and a PC hood?

Transparency comparisonPC transparency is 90%, glass transparency is 95%, but the naked eye does not seem to distinguish between too big, because it is 5%, ha ha,Only several meters can be measured by instruments.

Q:How to identify Ic constant current LED bulb?

Hello, LED market is now very confused, this problem is the use of LED lamps of the users are more concerned about the problem, the so-called IC constant current drive power refers to the LED lamp (commonly known as the transformer) with a constant stream of multifunctional IC chip, the IC is generally 5-8 feet (depending on the model and decision scheme), role is to ensure that the current through LED lamp is controlled in a relatively constant parameter, ensure the long-term stability of LED lamp work at constant current. When the input or output voltage is changed, the current through LED remains constant, so the constant current IC of the LED light stability and service life is directly related to the IC also includes internal short circuit protection, overtemperature protection function of open protection etc.
