The working principle of LED table lamp light source
Do you know what the working principle of the light source of LED table lamp is? If you want to know, just follow the editor to have a simple understanding!
The main parameters of LED light source work are VF, IF, and other related ones are color, color temperature, wavelength, brightness, luminous angle, efficiency, power consumption, etc. The LED is a PN junction diode, and only a sufficient forward voltage can be applied to conduct current. The VF forward voltage establishes a normal working state for the LED to emit light. The IF forward current promotes the LED to emit light. The brightness of the light is proportional to the current flowing. Proportional. Nominal voltage of white LED VF: 3.4V±0.2V. When the LED light source is mass produced, the VF of each batch of LEDs has a certain degree of discreteness. For the consistency required by the customer, the LED must be sold in different VF stages when leaving the factory; otherwise it will lead to the same batch of LED lamps. There are differences in brightness; LED IF operating current is selected according to application needs, and different current grades cannot be mixed.
In summary, the editor tells: a brief introduction to the relevant knowledge about the working principle of the light source of the LED table lamp.
