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

A light source, two power supply, three workmanship.Online shopping, I strongly suggest that you buy some reliable.

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:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?

The LED price of aluminum alloy 3W is probably about 30.

Q:Will the power of the LED bulb grow longer and longer? Why?

The LED bulb does not become more powerful for extended periods of time.As LED chip light emitting device of the PN junction has a negative temperature characteristic: with the increase of temperature, the conducting voltage drop caused current rise, therefore, when the LED bulb is lighted with the temperature rise of power consumption will be increased. But good circuit and parameter design can reduce the influence of this temperature.

Q:LED thread specifications for bulb bulbs?

Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!

Q:Led the bulb is flashing. What's wrong with it? How do you fix it?

The driving power inside is broken. If there is basic electronic knowledge, replace the inner capacitor. Most probably the electrolytic capacitor is broken.However, the cost of the bulb products is relatively low, and the cost of the repair is greater than the cost of the change.

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

The light effects of the three are different. Incandescent light minimum generally below 20Lm/W, the energy-saving efficiency of light in the 60-70Lm/W, the LED ball screw energy-saving lamp in the global market, the quality of the naked light in 100Lm/W, with the outside door cover will drop more than 10%.

Q:Choose which light bulb LED bulb is the healthiest

For home use, you can select LED bulb below 8W, with a color temperature below 3500K

Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!

If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
