Fig. 2 is schematic view of the front view of the invention.
Specific embodiment
In order to more fully understand those skilled in the art, this tests novel technical solution, below with reference to specific implementation
The preferred embodiments of the invention are described in example, but it is to be understood that these descriptions are intended merely to further illustrate this hair
Bright feature and advantage, rather than to the limitation that the invention patent requires.Based on the embodiments of the present invention, the common skill in this field
Art personnel every other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
The present invention is further described with preferred embodiment with reference to the accompanying drawing.
Referring to shown in Fig. 1 to 2, a kind of split type reflector using single light source involved in the present embodiment, including plano-convex
Lens 10, plano-convex lens 10 have convex front surface 11 and rear plane 12, and the front of rear plane 12 is provided with light source board 20, light source board
20 are equipped with the LED lamp bead 21 of pearl face vertically upward, and LED lamp bead 21 is equipped with the reflective cup body 30 that part is provide with LED lamp bead 21,
Reflective cup body 30 has the reflective rim of a cup 31 towards the plano-convex lens 10, and the reflective cup body 30 is by upper cup body 301 and lower cup
Body 302 forms, and the upper surface of the lower cup body 302 is bonded the lower end surface of upper cup body 301 and is horizontal plane.
In the present embodiment, by being spliced to form by two cup body split productions of different curvature radius, then by the two
One knockdown reflective cup body 30 converges the light of the generation of LED lamp bead 21 on light source board 20 with this, causes bent in different reflections
Under rate, reach the enhancing to the irradiation light area after plano-convex lens 10 is appeared, and the die sinking manufacture of reflective cup body 30 is also relatively simple.
Further, the radius of curvature on any configuration horizontal plane of the upper cup body 301 gradually subtracts from bottom to top
It is small；Radius of curvature on any configuration horizontal plane of the lower cup body 302 is gradually reduced from bottom to top.
Further, the radius of curvature on the lower end surface of the upper cup body 301 is greater than the song on the upper surface of lower cup body 302
Rate radius causes to reflect the generation of LED lamp bead 21 so that the radius of curvature of 302 reflective surface of lower cup body is less than upper cup body 301 on the whole
Light source after, lower section obtains stronger convergence, enhances light area below the visual field with this.
Further, the upper end of the reflective cup body 30 is equipped with the light barrier 32 that reflective rim of a cup 31 is covered in part, light barrier
32 have the light-blocking edge 321 of place in the horizontal plane, are arranged in horizontal light-blocking edge 321, so that it is smooth above irradiation light area,
Using comfortable；
Further, the upper mounting plate 33 that there is the upper cup body 301 surface to be furnished with mounting hole；The lower cup body 302 has
There is surface to be furnished with the lower installation board 34 of mounting hole, upper mounting plate 33 is set in upper cup body 301, the lower installation of setting on lower cup body 302
Plate 34, so that being bonded closely between the two, it is good to reach reflecting effect convenient for the installation of upper and lower cup body.
Further, the upper cup body 301 is structure as a whole with upper mounting plate 33；The lower cup body 302 and lower installation board
34 are structure as a whole, and convenient for molding manufacture, processing and fabricating is simple.
Further, the outer periphery of the plano-convex lens 10, which has, is embedded in along side 13, adding along side 13 is embedded in, convenient for flat
The installation of convex lens 10.
Split type reflector according to the present invention using single light source, by using split type upper cup body and lower cup body
Combination forms reflector entirety, reaches and carries out individually die sinking manufacture to the cup body of different curvature radius, so that cup body die sinking, manufacture
Simply, production is convenient；It is poor by the material flowability due to manufacture cup body, it is not easy to be opened, by fission die sinking manufacture, reach
To control is easily shunk to product, it is unlikely to deform；By cup surface reflective surface fairing after molding, reflecting effect is good, and light
Line reflection is uniform；By being arranged in horizontal light-blocking edge, so that it is smooth above irradiation light area, using comfortable；By on cup body
Mounting plate is set, convenient for the installation of upper and lower cup body, so that being bonded closely between the two, it is good to reach reflecting effect；By being embedded in along side
Add, convenient for the installation of plano-convex lens.
