Specific implementation mode
Below by way of specific embodiment, the present invention will be described in detail：
Fig. 1 is the stereogram exploded view of first embodiment of the invention LED light device, and Fig. 2 is LED light device shown in Fig. 1
The front view of middle light distribution device, Fig. 3 are the upward views of lens in LED light device shown in Fig. 2, which includes
Light distribution device 10 and luminescence unit 20, the light distribution device 10 are arranged in the top of the luminescence unit 20, which includes
At least one lens 11, the luminescence unit 20 include at least one LED light source 21, which is inverted trapezoidal structure, the lens
11 include light-emitting surface 112, which is arranged in the top surface of the lens 11, and the bottom of the lens 11 is provided with groove 111, should
Groove 111 includes the plane of incidence 1111 and medial surface 1112, which is arranged above the LED light source 21, the plane of incidence
1111 be quadrilateral structure, which to form being respectively facing the LED light source 21 close to the position of its each edge and protrude out
Four cambered surfaces 11121, each cambered surface 11121 cooperatively form the convex lens structures for optically focused with the light-emitting surface 112 respectively so that
It projects on the periphery that most of light that the LED light source 21 is sent out is biased to the light-emitting surface 112 respectively.
Referring to FIG. 3, the light-emitting surface 112 is quadrilateral structure similar with the plane of incidence 1111, and the light-emitting surface 112
While respectively with the plane of incidence 1111 while it is parallel, the area of the light-emitting surface 112 is more than the area of the plane of incidence 1111.The groove
111 be quadrangle cylindrical slot, which forms the top surface of the groove 111, the side of the groove 111 respectively with the incidence
The side in face 1111 connects.The plane of incidence 1111 is regular quadrangle structure.These cambered surfaces 11121 are close to the side of the plane of incidence 1111
The height highest for being positioned against the LED light source 21 and protruding out.
It please refers to Fig.1 and Fig. 2, the light distribution device 10 is bar shaped platy structure, multiple lens 11 are arranged in the light distribution device
10 bottom surface, at least corresponding LED light source 21 of each lens 11 are arranged.
Referring to FIG. 1, the LED light device 100 further includes radiating part 30, which is set as cuboid and connects
In the bottom of the luminescence unit 20, which is fixed on the top surface of the radiating part 30, which is equipped with multiple
Radiating fin 31.
When work, medial surface that most of light that the LED light source 21 on the luminescence unit 20 is sent out passes through the lens 11
1112 and the plane of incidence 1111 be refracted into the lens 11, this some light is biased to the light-emitting surface 112 respectively through the lens 11 again
Periphery is projected, and to form square focus spot on the ground, realizes the Uniform Illumination to entire ground areas.And due to the lens
11 overcome the plane of refraction disadvantage poor to light control ability, and so that the light distribution is filled by the way that bull collector lens 211 is arranged
It sets 10 and has converged most light, light utilization is made to reach 85% or more.The entirety of the light distribution device 10 is reduced simultaneously
Highly so that 100 overall volume of LED light device reduces, and can be set as relatively thin shape.
In conclusion LED light device 100 of the present invention and is set by the way that light distribution device 10 is arranged on the light distribution device 10
Multiple lens 11 are set, while groove 111 and light-emitting surface 112 are set on each lens 11 so that the LED light source 21 sends out big
Some light by the groove 111 medial surface 1112 and the plane of incidence 1111 after be biased to the periphery of the light-emitting surface 112 respectively and penetrate
Go out, to form square focus spot on the ground, in this way, can be realized to entirely by way of the rectangular splicing of ground hot spot
The Uniform Illumination of face range, therefore the LED light device 100 has the advantages of efficiency of light energy utilization higher, good illumination effect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent substitution, improvement and etc. done should be included within the scope of protection of the invention god.
