Problems solved by technology

In terms of light collection, the luminescent materials in traditional lamps do not have the light collection ability, and the light collection mainly uses a compound parabolic concentrator for concentrating light. However, the compound parabolic concentrator is bulky, causing troubles for the miniaturization and integration of lamps

Abstract

The invention discloses a phosphor with compound paraboloid light collecting capability and a preparation method thereof. The phosphor comprises a solid fluorescence conversion material defined by a first surface and a second surface, wherein the first surface is a plane and is an exciting light incident surface, the second surface is one of a paraboloid, a paraboloid-like surface, a spherical surface and a free-form surface, and the first surface is plated with an antireflection film layer. According to the invention, output light can be homogenized, the heat dissipation capacity is excellent, and thephosphor has the compound paraboloid light collecting capacity, so that the phosphor meets the high-power illumination use requirement.

Description

Technical field [0001] The present invention relates to phosphors prepared, particularly, with composite parabolic surface collecting capacity and preparation methods thereof. Background technique [0002] High-power lighting fixtures heat dissipation, collective lighting is a very important key technique. [0003] In terms of heat dissipation, the light-emitting material is difficult to heat dissipation in the traditional design. Even if there is a heat sink, it is basically a flat contact heat, the contact area is small, the heat dissipation effect is high, and the actual operating temperature of the phosphor is high and uneven causing the phosphor heat to quench, or even fry. The heat dissipation of fluorescent materials in high-power lighting has become a key technique. The phosphor of the present invention has a parabolic surface, a parabolic surface, a spherical or free surface and a heat sink, a large contact area having excellent heat dissipation capability, and simultane...
