Extended data:
The light bulb of LED lamp is introduced as follows:
Compared with incandescent bulbs and neon lights, LEDs have the following characteristics: the working voltage is very low (some are only a few volts); The working current is very small (some can only emit a few milliamps); Good impact and earthquake resistance, high reliability and long service life;
By adjusting the current intensity, the luminous intensity can be easily adjusted. Because of these characteristics, LED is used as a light source in some photoelectric control devices and as a signal display in many electronic devices. LED mobile phone, tablet computer and laptop screen will not cause harm to eyes.
