Description
Technical field
The utility model patent disclosure the high-power LED illuminating lamp of a kind of liquid heat radiation, belong to the technical field that LED encapsulation, LED are used.
Background technology
Along with the lifting of LED monomer chip power and the raising of brightness, LED is widely used in all kinds of lighting fields just gradually, more and more demonstrates its unique advantages in especially efficient at needs, energy-saving and environmental protection and highly reliable, the long-life field.But the raising of monomer chip power just means increasing considerably of LED operating current, and what bring is exactly the becoming increasingly conspicuous of heat dissipation problem in the high-power LED encapsulation process thereupon.For this reason, people have adopted the pedestal of various materials such as the metal, medium of a lot of high thermal conductivities as high-power LED encapsulation, designed panoramic radiator structure, the design that has can be satisfied heat radiation and require still to involve great expense, the simple design of great majority but can't be satisfied the heat radiation requirement of great power LED, and final result is not very desirable.So, seek efficient, succinct, cheap and safe and reliable high-power LED packaging method just becomes the target of pursuing in the industry.
Summary of the invention
The utility model patent disclosure be a kind of high-power LED illuminating lamp that adopts the preparation of liquid heat radiation packaging technology, this illuminating lamp comprises three major parts, the one, lampshade; The 2nd, light source assembly; The 3rd, as mainly the dispel the heat transparency liquid of material of high-power LED illuminating lamp cooling system.
The described lampshade of this patent has the contour structures of traditional lighting light fixture, and it can be toroidal, elliptical shape, rectangular-shaped, also can be radial and as shown in Figure 1 polygon-shaped.Lampshade mainly is made of the fixed pedestal at top, the lampshade shell that has the liquid hand-hole of centre and the Transparent lamp shade cover plate that the bottom has convex structure or plane structure.The transparent cover plate that has 1 or a plurality of convex structures is mainly used in the illuminating lamp that needs spotlight effect, and the transparent cover plate of plane structure is mainly used in the illuminating lamp that needs the floodlight effect.
The described light source assembly of this patent mainly comprises the heat sink substrate of metal heat sink, the bonded metal of 1 or many s' great power LED colour or white light source, adjusting led light source height, connects the cored screw of substrate and shell fixed pedestal.In illuminating lamp, whether adopt metal heat sink, decide, metal heat sink promptly need be installed when illuminating lamp is used for spotlighting improve spotlight effect by the operating characteristic of illuminating lamp; When illuminating lamp is used for floodlighting, can be without metal heat sink but directly led light source is installed on the substrate.Substrate can be used metal material, also can adopt the above copper coated foil plate material of FR-4 specification.
The described transparency liquid of this patent mainly adopts the deionized water of using always on the semiconductor devices production line in highly purified industrial alcohol or the microelectronics industry.
The technical scheme that its technical problem that solves this patent adopts is: high-power LED light source is bonded on the substrate after being fixed in metal heat sink by sintering process, and the assembling cored screw constitutes the led light source assembly in substrate center; Increase a transparent cover plate in the light fixture bottom when transforming the conventional lamp outer cover, this cover plate designs and produces to plane, perhaps is the convex structure that one or more and high-power LED light source number are complementary; The other end of cored screw in the light source assembly is fixed on the fixed pedestal of light fixture; Adopt sealing means that transparent bottom cover plate is held in the light fixture bottom; At last transparency liquid is filled with the housing of LED light fixture and is done sealing, realize thus this patent adopt liquid as cooling material by the great power LED conception of high efficiency and heat radiation at work.
Different with 180 ° of plane contact radiating modes of routine, the heat that the led light source that is surrounded by transparency liquid fully in this patent illuminating lamp produces in lighting process, will be along 360 ° of spheres to the transparency liquid transmission, convection current and conduction by liquid are delivered to lamp outer casing with heat again, are radiated in the lighting environment at last and go.Such LED illuminating lamp is actually an entity radiator that surface area is very big, and good radiating condition will significantly improve the actual life of LED illuminating lamp fast, effectively delay the optical attenuation of led light source.By regulating the distance between led light source and the convex structural base cover plate, can adjust the irradiating angle of LED illuminating lamp; By changing the radius of curvature and the configuration design of convex structure on the LED illuminating lamp bottom cover plate, can regulate the spotlight effect of illuminating lamp effectively.
