Embodiment 1

[0025] combine Figure 1-2 In this embodiment, the manufacture of the sapphire heat-conducting light-transmitting plate is mainly carried out in two steps, and the first sapphire heat-conducting light-transmitting plate and the second sapphire heat-conducting light-transmitting plate are manufactured respectively. First, mix yellow phosphor powder and high thermal conductivity epoxy resin glue in a mass ratio of 1:8, and knead three times at 30°C until the phosphor powder and high thermal conductivity epoxy resin glue are evenly mixed. The mixed rubber material is sandwiched between two layers of release paper, and laminated with a film laminating machine to form a phosphor film 2 with a thickness of 500 μm. Cut the phosphor powder film into a suitable size for the sapphire transparent heat conduction plate 1, and use an automatic gluer to paste the phosphor powder film on the 35×1×0.8mm sapphire transparent heat conduction plate 1, and the two ends of the sapphire transparent...

Embodiment 2

[0027] combine Figure 1-2 , the basic steps of this example are the same as Example 1, the difference is that the yellow phosphor is first mixed with the high thermal conductivity epoxy resin glue in a mass ratio of 1:10, and mixed five times at 35°C until the phosphor powder and the high thermal conductivity The epoxy resin glue is mixed evenly. The mixed rubber material is sandwiched between two layers of release paper, and laminated with a film laminating machine to form a phosphor film 2 with a thickness of 500 μm. Cut the phosphor powder film into a suitable size for the sapphire transparent heat conduction plate 1, and use an automatic gluer to paste the film mixed with phosphor powder on the 35×1×0.8mm sapphire transparent heat conduction plate 1, and the two ends of the sapphire transparent heat conduction plate There are metal electrodes 5 for connecting the chip on the sapphire heat-conducting light-transmitting board light-emitting body and other external structur...

Abstract

The invention provides a method for manufacturing illuminant on a transparent sapphire heat conductive plate. The method includes two steps: manufacturing a first sapphire heat conducting light-transmitting plate for fixing chips, and manufacturing a second sapphire heat conducting light-transmitting plate which is closely attached with fluorescent powder film. The obtained illuminant on the sapphire heat conducting light-transmitting plates can be connected with an upper wiring plate and a lamp base in a grooved and clamped manner. The method is simple in technology and easy to operate, and heat generated by the chips can be transferred out by not mainly relying on heat radiation, but in a heat conducting manner via a base directly.

Description

(1) Technical field [0001] The invention belongs to the technical field of LED encapsulation, and in particular relates to a method for manufacturing a luminous body on a sapphire transparent heat conduction plate. (2) Background technology [0002] With the deterioration of the global environment and the increasingly prominent problems of resource scarcity, people's demand for energy-saving and environmentally friendly products is also becoming stronger. The electricity required for various lighting in the world is huge, and my country's lighting electricity consumption accounts for about 12% of the total electricity consumption of the whole society. Therefore, the development of energy-saving and environmentally friendly lighting lamps has become a research focus in various countries in recent years. [0003] LED has the advantages of high light efficiency, low energy consumption, long life, environmental protection, etc., and is the most ideal substitute for traditional l...
