Abstract
An embodiment of the invention discloses an LED light source module and a lens thereof. A first side of the lens is provided with a concave which concaves towards the interior of the lens, the concave is used for accommodating a light source, the concave wall forms an incident plane of the lens, and a second side of the lens, connected with the first side, is a convex smooth curve which forms an exit plane of the lens. A reflection plane for reflecting lights to the exit plane is jointly formed by the concave surrounded by first side and pyramid walls of a plurality of pyramid concaves which concave from the first side to the interior of the lens. For the lens of the embodiment of the LED light source module, since the reflection plane for reflecting lights to the exit plane is jointly form by the concave surrounded by first side and pyramid walls of pyramid concaves which concave from the first side to the interior of the lens, the light emitted to the first side can be emitted after being reflected from each angle to the second side, so that technical effect for uniform light is achieved.
Description
Technical field
The present invention relates to optical technical field, relate in particular to a kind of led light source module and lens thereof.
Background technology
Light emitting diode (Light Emitting Diode, LED) low in energy consumption because of having, the life-span is long, volume is little and characteristic such as brightness height has been widely applied to many fields.
LED light source module can be divided into two kinds of straight-down negative and side-light types by the difference of the distributing position of its semiconductor light-emitting elements LED; And the LED light source module of existing straight-down negative improves light utilization through lenticule is set above LED; Said lenticular bottom surface is smooth and be similar to plane mirror; Cause the reflection angle of internal light single, there is the uneven defective of bright dipping in light reflected after exit facet penetrates.
Summary of the invention
Embodiment of the invention technical problem to be solved is, a kind of lens of bright dipping uniformity are provided.
The further technical problem to be solved of the embodiment of the invention is, a kind of led light source module of bright dipping uniformity is provided.
In order to solve the problems of the technologies described above; The embodiment of the invention has proposed a kind of lens; First side of said lens is provided with to the pit of lens internal recess with ccontaining light source; The hole wall of pit constitutes the plane of incidence of lens, and second side that is connected in first side of lens is the smooth surface of evagination, and said smooth surface constitutes the exit facet of lens; Said first side also is formed with the reflecting surface of light reflection to exit facet around said pit, and said reflecting surface is made up of a plurality of awl walls that cave in to the pyramid-shaped of lens internal recess from first side jointly.
Further, the pyramid-shaped depression is tetrapyamid shape or triangular taper.
Further, the depression of the pyramid-shaped on said first side is a plurality of concentric ring-shaped arrangements.
Further, be arranged in pyramid-shaped concave shape in the same annulus and measure-alike, and big more from the floor space of the pyramid-shaped depression of distance of center circle in big more donut.
Further, the recessed deep equality of the depression of the pyramid-shaped in each donut.
Further, first side around evenly be provided with a plurality of legs.
Further, it is recessed also to be the spherical crown shape to the lens middle part in the middle part of the said smooth surface.
Further, said smooth surface is the axisymmetric curved surface in center.
Correspondingly, the embodiment of the invention also provides a kind of led light source module, comprises led light source and covers in the outside aforesaid lens of led light source.
The led light source module of the embodiment of the invention and the beneficial effect of lens thereof are: also form the reflecting surface of light reflection to exit facet around said pit through being employed in first side; The technological means that said reflecting surface is made up of a plurality of awl walls that cave in to the pyramid-shaped of lens internal recess from first side jointly; Thereby the light of directive first side is reflexed to second side and penetrates from all angles, reach the technique effect of bright dipping uniformity.

The specific embodiment
Please refer to Fig. 1 ~ Fig. 5, the embodiment of the invention provides a kind of lens, roughly is hemispherical, has a central shaft oo ', is processed by transparent material, and this material can be polypropylene acid formicester, polycarbonate or this acid propylene of carbon acetate.Said lens comprise first side 10 and second side 20 that is connected in first side 10.
Evenly be provided with a plurality of legs 15 around first side 10, leg 15 is used for lens are fixed to the correspondence position of circuit board.Leg 15 can be 2～5, and in this embodiment, leg 15 is preferably 3.
The embodiment of the invention also provides a kind of led light source module that uses said lens; The led light source module is used for backlight or lighting; Comprise led light source 30 and cover in the outside aforesaid lens of led light source 30; Particularly, be equipped with the led light source 30 with its coupling in the pit 11, led light source 30 also is positioned on the central axis oo '.
Please refer to Fig. 6; When the light that sends from LED is incident upon first anti-/ plane of refraction 21 and second anti-/ plane of refraction 23 by the plane of incidence; Since first anti-/ plane of refraction 21 with second instead/plane of refraction 23 corresponding reflectings surface the total reflection effect; The pyramid-shaped depression 13 that part anaclasis and going out, most of light are reflected onto 10, the first sides 10, first side just break up the light that reflects back and reflex to again first anti-/ plane of refraction 21 with second instead/plane of refraction 23 and penetrating; And said shape, size and the arrangement architecture of pyramid-shaped depression 13 make and are evenly distributed shadow-free through the light that first anti-/ plane of refraction 21 and second anti-/ plane of refraction 23 penetrates.Through test, the led light source module of the embodiment of the invention can with the average intensity angle of flare θ of light emitting diode by original+/-60 ° be diffused into+/-70 °.
The above is the specific embodiment of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also are regarded as protection scope of the present invention.
