Problems solved by technology

There are many disadvantages in this packaging process. For example, the packaging glue is not easy to mix evenly when dispensing glue with a glue dispenser; There are many defective chips; many production processes, long working hours, low efficiency, high cost, low yield and poor stability
[0005] To sum up, the current LED white light source has obvious shortcomings in many aspects such as production, use, and preparation cost. Especially when the LED white light source is applied as a surface light source, the existing LED white light source often cannot solve the problem of uniform light emission. The problem of degree, can not well meet the needs of actual use and industrial production

Abstract

The invention discloses an electroluminescent film. The electroluminescent film comprises, by mass, 48.05-49.21% of phosphor, 19.69% of methyl vinyl silicone rubber, 8.68-9.84% of methyl vinyl MQ high-viscosity silicone resin, 8.68-9.84% of fumed silica, 8.68-9.84% of vinyl silicone oil, 0.019-0.59% of hydroxyl silicone oil, 0.01-0.98% of a radiation and heat dissipation nano-material, 0.19% of hydrosilicone oil, 0.00009-0.0019% of an inhibitor, 0.0006-0.0019% of a catalyst and 0.19-0.98% of a tackifier. The electroluminescent film made in the invention has simple formula, is convenient to make, has obviously better photoelectricity, industrial production convenience and unit production cost than present LED luminescence structures, and has wide application space.

Description

technical field [0001] The invention relates to the field of luminous lighting, in particular to an electroluminescent film and a preparation method thereof. Background technique [0002] Semiconductor and LED lighting technology is the third generation of electric light source. Compared with the first generation of thermal radiation electric light source and the second generation of gas discharge electric light source, LED light source has high efficiency, and its service life is 100 times that of incandescent lamp. Energy saving is more than that of sodium lamp. 70% of the total, so it has been widely used and developed by leaps and bounds. However, LED light sources also have many disadvantages such as high heat generation, dazzling, complicated packaging process, high cost, and many failures. [0003] In the process of white LED preparation, packaging is the key link. Specifically, the light-emitting mechanism of semiconductor materials determines that a single LED chip...
