preparation example Construction

[0060] The preparation process of the rare earth medium slurry includes:

[0061] 1) Preparation of glass-ceramic powder

[0062] Mix the well-proportioned glass-ceramic powder evenly in a mixer and put it in a bell furnace for melting; the melting temperature is 800-1200 degrees Celsius, the peak temperature is kept for 1-5 hours, and the glass slag is obtained by water quenching; the glass slag is As for grinding in a planetary ball mill for 2 to 4 hours to obtain glass powder with an average particle size not greater than 5 microns;

[0063] 2) Preparation of inorganic binder phase and organic solvent carrier

[0064] The preparation of the inorganic adhesive phase and the organic solvent carrier is to dissolve the main solvent, thickener, surfactant, thixotropic agent, and gelling agent in the organic solvent carrier in water at 80-100°C for several hours, and adjust the increase Thickener, diluent content, just adjust the viscosity of the organic solvent carrier within ...

Abstract

The invention discloses a Re-alsic-rare-earth-aluminum-silicon-carbide-based LED rare earth thick film circuit electric light source device which is characterized in that the device comprises a substrate and serial rare earth electronic slurry, the serial rare earth electronic slurry is prepared on the substrate in the mode of a thick film circuit, the serial rare earth electronic slurry comprises coating slurry, rare earth resistance slurry, rare earth electrode slurry and rare earth medium slurry. Substrate vacuum impregnation ingredients comprise, by weight ratio, 2-7% of magnesium and 1.5-2.5% of rare earth metal neodymium and scandium together except for aluminum. The Re-alsic-rare-earth-aluminum-silicon-carbide-based LED rare earth thick film circuit electric light source device is good in compatibility, firm in combination, large in power density, high in thermal shock resistance, high in heat dissipation efficiency, environmentally friendly, capable of saving energy and safe and reliable, and good match of the device and LED chips is achieved.

Description

technical field [0001] The invention relates to the technical field of high-power LED electric light source, and more specifically relates to a high-efficiency high-power LED electric light source assembly with wide application. Background technique [0002] In the sustainable development strategy established by our country, two important aspects involved are new energy sources, light sources, environmental protection and improving energy utilization rate and improving energy structure. In the field of LED electric light source, new electric light source components require high power, high light efficiency, strong thermal shock resistance, easy processing, environmental protection, safety and reliability. Re-alsic-rare earth-aluminum silicon carbide-based LEDs with rare earth thick film circuit electric light source components that can meet the above requirements are a better choice. At present, this high-power electric light source module is in the initial development and ...
