LEDs Light Bulb
A solid-state light-emitting element made of a semiconductor body material, the principle of light-emitting is to convert electrical energy into light, that is, to apply a current to a compound semiconductor, and through the combination of electrons and holes, excess energy is released in the form of light to achieve a luminous effect. It belongs to cold luminescence and has a life span of more than 100,000 hours.
At present, LED bulbs have been widely used in many products in life, such as backlights for mobile phones and PDA products, indicator lights for information and consumer electronics, industrial instrumentation, indicator lights and vehicle lights for automobiles, and large-scale advertisements.
