Form a whole, and aluminium base is installed with below microlens array；LED light is uniformly installed on the aluminium base
Source；The radiator is fixedly mounted on the lower end of aluminium base.
Further, in order that the light that light source is sent preferably is irradiated to surrounding, the Fresnel Lenses and convex lens it
Between distance be 2-5cm.
Further, in order that the light that light source is sent more is concentrated, particle eyeglass on the microlens array inclines
Rake angle is 65-85 °.
Further, for more preferable heat conduction, thermally conductive sheet is additionally provided between the aluminium base and radiator.
Further, in order that light efficiency is higher, the place that LED light source is not provided with the aluminium base is coated with instead
Light powder.
The beneficial effects of the utility model are：The microlens array LED light source structure based on optical space technology, use
Simply, the microlens array LED light source structure based on optical space technology is switched on power during use, LED light source is launched
Light, light can be concentrated to convex lens, light via the aggregation of microlens array to be launched to luxuriant and rich with fragrance alunite after planoconvex lens is assembled again
Your lens, Fresnel Lenses dissipate uniform light to surrounding, make range of exposures outer ring and inner ring brightness substantially always,
Also intensity of illumination is made to become higher, radiator can reduce the temperature of device interior, improve service life, and should be based on optics
The microlens array LED light source structure of space technology, improves illumination brightness, also improves illumination range, stability during work
By force, it is adapted to promote the use of.
