Abstract
Description
technical field
[0001] The invention relates to the technical field of LED devices, in particular to a portable LED lighting lamp. Background technique
[0002] Light-emitting diodes are referred to as LEDs for short. Made of compounds containing gallium, arsenic, phosphorus, nitrogen, etc. Visible light can be radiated when electrons and holes recombine, so they can be used to make light-emitting diodes. It is used as an indicator light in circuits and instruments, or as a text or number display. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to chemical properties, it is divided into organic light-emitting diode OLED and inorganic light-emitting diode LED. It is a type of semiconductor diode that converts electrical energy into light energy. Like ordinary diodes, light-emitting diodes are composed of a PN junction and also have unidirectional c...
