Q:LED can the bulb be used in the bathroom?

of couse Yes, but LED kitchen and toilet light is recommended

Q:What's the cause of the noise during the aging of LED bulb bulbs?

Either AC or DC LED lighting there will be a power module, a small hidden in the lamp body, the daily working state can produce high temperature, if the AC power supply temperature will be higher, because the lamp body appears to flicker, high temperature and long time will lead to the power supply module parts welding, weld or aging, so a lot of alternating current LED lighting the metal shell, to facilitate heat dissipation, the DC power supply is adopted to eliminate the flicker, reduces the electrical power, so the DC temperature should be low.

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 does the LED bulb go with the power?

voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,

Q:Are there any differences between negative ion bulb and LED bulb?

The negative ion belongs to bullshit type, the concept of things!

Q:Is it possible to manually weld LED bulb bulbs?

You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off

Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?

100lM/W LED bulb, 4-5W can be replaced. If it is white 4W can be, if it is warm white (yellow light), preferably 5W, mainly human eye feeling, white light than Huang Guangliang.4-5W LED bulb, equivalent to 12-15W energy-saving lamps

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

4 and three is different. An incandescent lamp relies on heating the electrode wire to send out visible light. The energy-saving lamp releases the electrons by conducting the electrode wire, while the LED light is led by the diode.

Q:Choose which light bulb LED bulb is the healthiest

Choose LED lights, first, no strobe, strobe damage to the eyes, second color index to be high, true and clear. For the quality, choose to heat better, high power factor, so that the relative power of the lamp, power saving, durable

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

If the radiator has a large radiating area, the temperature is low
