Problems solved by technology

[0004] China will become the main driving force for the development of the global LED market. With the increase of market demand, the functions, performance and convenience of use of various diodes are also gradually increasing. In the process of use, many diodes are installed Sometimes due to the different installation environment and installation conditions, the pin length of many diodes will be insufficient, which is inconvenient to install, and there are still many light-emitting diodes whose brightness decreases obviously after a period of use. For these situations that affect normal use, this The patent provides a light-emitting diode for high-brightness semiconductor lighting that can adjust the length of the pin and increase the brightness

Description

Technical field: [0001] The invention relates to the technical field of semiconductor lighting, in particular to a heat sink material for a light-emitting diode used in high-brightness semiconductor lighting. Background technique: [0002] Light-emitting diodes are referred to as LEDs for short. Made of compounds containing Gallium (Ga), Arsenic (As), Phosphorus (P), Nitrogen (N), 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. [0003] LED products are mainly used in the three major fields of backlight, color screen and ...
