Description

Technical field: [0001] The invention relates to the technical field of semiconductor lighting, in particular to a heat sink material with high thermal matching performance for 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, corundum powder 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 indoor l...
