Detailed Description
In order to make the technical means, the creation features, the achievement objectives and the functions of the present invention easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, the embodiment adopts the following technical scheme that the integrated light mixing lens reflective cup capable of improving the refractive index comprises a lens part (1), a reflector part (2), a light mixing optical surface (3), a threaded structure surface (4), a compound eye structure (5) and a threaded optical structure surface (6), and is characterized in that the integrated lens reflective cup is manufactured by an integrated forming process, and the whole integral lens reflective cup can be divided into two parts, namely the lens part (1) and the reflector part (2); the inner wall surface of the reflector part (2) is designed and formed with a threaded optical structure surface (6); a thread structure surface (4) is formed on the inner wall surface of the lens part (1), a compound eye structure (5) is designed in the center of an inner cavity, and a light mixing optical surface (3) is symmetrically arranged and matched with the compound eye structure (5); the light mixing optical surface (3) is a symmetrical special-shaped refraction surface with a concave middle part; the thread structure surface (4) and the thread optical structure surface (6) are formed by arranging a plurality of convex lenses.
The light mixing optical surface (3) is a light incident surface and is also a primary light mixing surface.
Wherein the thread structure surface (4) and the thread optical structure surface (6) are secondary light mixing surfaces.
The lens part (1) is reserved and provided with hole site matching installation lamp beads, and is specifically positioned on the light mixing optical surface (3).
The present embodiment is described by taking the above scheme as an example, and referring to fig. 2 to 4.
Compare in the tradition, the utility model relates to an integral type specifically is that lens and anti-light cup form through integrated into one piece's technology preparation, and compares the part and be integrated into one piece's lens anti-light cup equally, the utility model discloses then there is the improved design of making the practicality, and its structure of current integrated lens anti-light cup can see figure 2 to figure 3, and the defect that exists is that the part of lens is still TIR lens, and the internal face of anti-light body part is the anti-light cup for the rhombus structure, and the light effect that the rhombus structure came out can lead to the facula colour inhomogeneous, refraction inefficiency scheduling problem to not fully satisfactory.
And the utility model discloses a change embodies on mixed light optical surface, helicitic texture surface and the helicitic texture surface, wherein helicitic texture surface and helicitic texture surface are arranged by a plurality of convex lens and form, and mixed light optical surface is the special-shaped refracting surface of symmetry that a centre is sunken.
If the lamp beads are formed by matching the blue light-emitting LED with fluorescent powder for exciting yellow light, the deviation of yellow and blue can be obviously seen on the working surface when light passes through the lens and is refracted to the working surface on a common integral lens reflecting cup. However, the utility model can not, see fig. 4 for details, because the light mixing optical surface 10 is a symmetrical special-shaped refraction surface with a concave middle part, the left part makes the near-field light 12 refract to the region a of the facula through the special-shaped refraction surface, and the right part makes the near-field light 12 refract to the region B of the facula through the special-shaped refraction surface; the left portion causes far-field rays 13 to be refracted through the shaped refracting surface to region B of the spot, while the right portion causes far-field rays 13 to be refracted through the shaped refracting surface to region a of the spot. Although there is the defect that LED wafer luminous position is different with the luminescent powder luminous position for the colour temperature of the light that different positions sent is different, but we make the light that any position came out through the design of the mixed light optical surface of special-shaped refracting surface can both evenly distributed to the working face through mixed light optical surface, wherein thread structure surface and thread optical structure surface are secondary mixed light face, from top to bottom by a plurality of convex lens because of both, around arranging and forming, and the small lens has certain focus, so local parallel light can spotlight on a certain small lens, light can scatter out after the focus, so that the light that every convex lens jetted out all can superpose each other, thereby realize mixed light to a certain extent again.
For the lamp which can improve the refraction efficiency to a certain extent after being electroplated, the design can not only remove the electroplating process, but also obviously improve the refraction efficiency and enlarge the light field even on the premise of not increasing spare parts and assembly difficulty, and the purpose that the light coming out of the refraction surface can be uniformly distributed on the working surface can be achieved by matching with the light mixing optical surface with special-shaped design, and the light can be produced and manufactured by only one set of die, thereby reducing the cost and the assembly difficulty.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
