Guangmai Technology is proffesional in making the CUV UVA COB LED Chip Matrix Array 390nm 395nm 400nm 405nm 410nm.
UV-LED is a newly developed solid-state LED light source whose spectral band is concentrated in the UV range. In recent years, with the rapid development of LED technology and the continuous improvement of LED chip luminous efficiency and packaging technology, its huge application value is increasingly attracting people's attention and has become a new hot spot for research and investment in the global semiconductor field. Compared with traditional UV light sources, UV-LED has many unique advantages such as low power consumption, fast luminous response, high reliability, high radiation efficiency, long life, no pollution to the environment and compact structure. It is expected to replace the existing UV The first choice for high-pressure mercury lamps.

Power range from 10 watt to 300 watt!
UV-LED packaging is a research topic involving multiple disciplines (such as optics, heat, electricity, machinery, materials, etc.). From a certain perspective, a good package structure design requires an understanding and application of the physical nature of heat, optics, and materials. Therefore, the packaging design of UV-LED devices should be carried out at the same time as the chip design, and comprehensive consideration of light, heat, electricity, structure, etc. is required. Among them, light is the purpose of UV-LED packaging, and heat is the key. Electricity, machinery and materials are the means, and performance is its concrete manifestation. 1. Heat dissipation substrate solution For heat dissipation substrates, FR-4PCB (Printed Circuit Board, printed circuit board) and MCPCB (Metal Core PCB, MCPCB, metal-based printed circuit board) have been more researched at home and abroad. Thermal conductivity The rate is 0.25-10W/(m·K). For low-power electronic components, it can still meet the heat dissipation requirements, but for high-power electronic components above 30W, ordinary PCB boards cannot meet the heat dissipation requirements. This product draws on the thermoelectric separation design concept and uses metal bosses or high thermal conductivity ceramics (Al2O3 or AlN) as a micro heat sink, so that the heat generated by the UV-LED module during the working process can quickly diffuse to the outside along the micro heat sink To avoid the risk of premature failure due to poor heat dissipation and reduced reliability of components. If a metal boss is used as a micro heat sink, the thermal conductivity of the substrate can be as high as 380W/m·K, and the thermal resistance is as low as 0.1°C/W; if aluminum nitride ceramic is used as the package heat dissipation substrate material, DBC/AMB can be used The high temperature bonding process or DPC thin film process completes the production of copper and circuits on the surface of the ceramic substrate. The overall thermal conductivity of the substrate is as high as 170-230W/m·K, and the thermal resistance is as low as 0.32°C/W or less.
