Description
Technical field
The invention belongs to heat abstractor, be 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 the industries such as illumination, household electrical appliances, IT is more and more extensive.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 has designed the LED minitype projection machine just towards the future development of microminiaturization, lightweight, higher image quality.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.High because of LED light source brightness, power is high, optical lens can produce very high heat, if this heat can not in time shed but be gathered in inside, the normal use of projector will be affected, 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 affect the use of projector more, even shortens its serviceable life, or damages 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 larger could satisfy the heat radiation requirement, causes projector's volume large, can not satisfy microminiaturized requirement.In addition, the heat radiation of plastic cement heat radiator is inhomogeneous, can affect the result of use of projector, and easily aging, and serviceable life is short.
Summary of the invention
The invention provides a kind of LED minitype projection machine optical lens heat abstractor, volume compact, lightweight, perfect heat-dissipating.
for achieving the above object, the technical solution used in the present invention is: a kind of LED minitype projection machine optical lens heat abstractor, has aluminum alloy base, LED light source is fixedly mounted on this aluminum alloy base, the LED light source side is installed with the aluminium alloy reflecting wall on aluminum alloy base, being installed with aluminum_alloy cover on aluminum alloy base above LED light source pushes up, so that described LED light source is positioned at by aluminum alloy base, it is indoor that aluminium alloy reflecting wall and aluminum_alloy cover push up the light that surrounds, at the aluminum alloy base that surrounds the light chamber, aluminium alloy reflecting wall or aluminum_alloy cover offer light hole on pushing up, the aluminium alloy lens barrel is installed on described aluminum alloy base, this aluminium alloy lens barrel is corresponding with light hole.
Further, described LED light source is fixedly mounted on aluminum alloy base through notch is dismountable.
Further, the surface of described aluminum 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 aluminum alloy base, aluminium alloy reflecting wall, aluminum_alloy cover top and aluminium alloy lens barrel is black.
Characteristics of the present invention are: LED light source is fixedly mounted on aluminum alloy base, the heat that LED light source produces can be delivered to rapidly on aluminum alloy base, then is dispersed in surrounding air rapidly and uniformly through aluminium alloy reflecting wall, aluminum_alloy cover top and aluminium alloy lens barrel.The existing thermolysis in light chamber by aluminum alloy base, aluminium alloy reflecting wall and aluminum_alloy cover top surround has again the insulation blocking effect of pair LED light source, prevents that foreign matter from entering the light chamber and affecting the imaging of optical systems quality.The aluminum alloy material that aluminum 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 lightweight, 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.
