Anonymous users2024-01-24The incandescent lamp will reach a very high temperature when it is working, and the inside of the bulb is vacuum, so that when the incandescent lamp is working, the air pressure inside is smaller than the air pressure outside, and an air pressure difference is formed, if it is an incandescent lamp of not very good quality, it will explode for a long time. It is recommended to buy bulbs made by regular manufacturers.
The bathroom is mainly for bathing.
Water vapor. Relatively high, incandescent lamps, including frost lamps, the temperature when lit is not very different from the temperature of the water vapor, but after taking a bath and turning off the light, the steam in the hall will disperse after a while, and the air temperature will drop quickly. >>>More
Remove it, connect the broken wire, wrap it with insulating tape, and install it again, OK.
LED lights need to be lit driver, the driver is the output of constant current current switching power supply, the quality or debugging is not good, when the output current is abnormal, there is often a very low frequency (a few hertz) low-frequency oscillation, LED light flashing phenomenon. When purchasing, you should test before purchasing, if you use DC to drive the LED light directly, there will be no light flickering phenomenon. >>>More
The lamp ports of energy-saving lamps are usually Luokou, so just buy a Luokou incandescent bulb and install it.
Do not take it.
The dimming principle of incandescent lamps is very simple, that is, a variable resistance (knob to adjust the size of the resistance) The principle of energy-saving lamps is electrode discharge. The dimming condition is to control the ionization of the gas in the lamp, and the adjustment is to control the discharge frequency and wax sensitivity (adjustable ballast). >>>More
