Description
Technical field
The utility model belongs to heat abstractor, is specifically related to a kind of LED minitype projection machine optical lens heat abstractor.
Background technology
In recent years, the led light source technology develops rapidly, and the use in industries such as illumination, household electrical appliances, IT more and more widely.For projector, along with the lifting of led light source technology, it also will welcome a new industry and use.And along with the raising of people's living standard, LED shadow casting technique is just developing towards the direction of microminiaturization, lightweight, high image qualityization, has designed the LED minitype projection machine.In LED minitype projection machine inside led light source, image-forming component and electronic component etc. are arranged, led light source is arranged in optical lens, and optical lens is the core component of minitype projection machine.Because of led light source brightness height, power height, optical lens can produce very high heat, if this heat can not in time shed but accumulate in inside, the normal use of projector will be influenced, so the heat dispersion of optical lens has decisive influence to the heat dispersion of projector's integral body.In addition, minitype projection machine is because its inner space is little, and element is intensive, and heat is difficult to shed more, and the high temperature that the gathering of heat produces will influence the use of projector more, even shortens its serviceable life, or the damage optical element.Present LED minitype projection machine optical lens normally adopts the plastic cement heat radiator to dispel the heat, but needs the plastic cement heat radiator that usage quantity is more, area is bigger could satisfy the heat radiation requirement, causes projector's volume big, can not satisfy microminiaturized requirement.In addition, the heat radiation of plastic cement heat radiator is inhomogeneous, can influence the result of use of projector, and easily aging, and serviceable life is short.
The utility model content
The utility model provides a kind of LED minitype projection machine optical lens heat abstractor, and volume compact is in light weight, perfect heat-dissipating.
For achieving the above object, the technical solution adopted in the utility model is: a kind of LED minitype projection machine optical lens heat abstractor, has the aluminium alloy base, led light source is fixedly mounted on this aluminium alloy base, the led light source side is installed with the aluminium alloy reflecting wall on the aluminium alloy base, the led light source top is installed with the aluminum_alloy cover top on the aluminium alloy base, so that described led light source is positioned at by the aluminium alloy base, the light that aluminium alloy reflecting wall and aluminum_alloy cover top surround is indoor, surrounding the aluminium alloy base of light chamber, offer light hole on aluminium alloy reflecting wall or the aluminum_alloy cover top, on the described aluminium alloy base aluminium alloy lens barrel is installed, this aluminium alloy lens barrel is corresponding with light hole.
Further, described led light source is fixedly mounted on the aluminium alloy base through the draw-in groove structure is dismountable.
Further, the surface of described aluminium alloy base, aluminium alloy reflecting wall, aluminum_alloy cover top and aluminium alloy lens barrel is equipped with electroformed layer.
Further, the surface of described aluminium alloy base, aluminium alloy reflecting wall, aluminum_alloy cover top and aluminium alloy lens barrel is black.
Characteristics of the present utility model are: led light source is fixedly mounted on the aluminium alloy base, the heat that led light source produces can be delivered to rapidly on the aluminium alloy base, is dispersed in the surrounding air rapidly and uniformly through aluminium alloy reflecting wall, aluminum_alloy cover top and aluminium alloy lens barrel then.The existing thermolysis in light chamber by aluminium alloy base, aluminium alloy reflecting wall and aluminum_alloy cover top surround has the insulation blocking effect of pair led light source again, prevents that foreign matter from entering the image quality that the light chamber influences optical system.The aluminum alloy material that aluminium alloy base, aluminium alloy reflecting wall, aluminum_alloy cover top and aluminium alloy lens barrel adopt has high thermal conductivity coefficient, and heat conduction is fast, is good heat sink material, avoid accumulation of heat, and density is little, and is in light weight, meets the requirement of optical lens lightweight, microminiaturization.Surface treatment becomes black, can improve the heat loss through radiation effect.The electroformed layer on surface can strengthen resistance to elevated temperatures, increases the service life.
