Abstract
The utility model discloses a uniform light lens used for a light emitting diode (LED) lamp. The uniform light lens used for the LED lamp comprises a lens body. An indent light splitting part is arranged on the lens body and comprises a center light distribution part and a side light distribution part which is arranged on the periphery of the center light distribution part in an annular mode. An LED light source assembly is arranged below the lens body, the center part of light emitted by the LED light source assembly is directly transmitted out by the center light distribution part, one part of remaining light emitted by the LED light source assembly is refracted by the side face light distribution part, and the other part of the remaining light is reflected for multiple times. Due to the fact that after the light in the non-center part is refracted or reflected, the light is emitted with direction changed, the light can be relatively sent out uniformly so that uniform light illumination can be achieved.
Description
Technical field
The utility model relates to a kind of even optical lens of the LED of being applied to light fixture.
Background technology
Because the unit are caloric value of led chip is very large, now a lot of LED light fixtures all adopt the led chip of a plurality of dispersions to substitute the led chip of single relatively high power, to improve LED light fixture radiating efficiency, improve its life-span, but because led light source has certain light-gathering, and the light source area of this LED light fixture is larger, even light optical design towards such light fixture is comparatively complicated, at present, even light solution for such LED light fixture is to adopt reflector, but the light of reflector control is very limited, is difficult to uniform light distribution, and reflector is easily received dust, the factor affecting such as plated film is aging, practical application effect is bad.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of even optical lens of the LED of being applied to light fixture, and this even optical lens can be good at solving the uniform light distribution problem of the larger LED light fixture of light source area.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of even optical lens that is applied to the LED light fixture is characterized in that comprising lens, is provided with some indent spectrum parts corresponding with the led light source assembly on the described lens.
Be provided with an indent spectrum part on the described lens, and this indent spectrum part is arranged on the lens centre position.
Described indent spectrum part includes the side luminous intensity distribution section that central luminous intensity distribution section and annular are arranged on central luminous intensity distribution section periphery.
The beneficial effects of the utility model are: be provided with the indent spectrum part at lens, this indent spectrum part includes central luminous intensity distribution section, and annular is arranged on the side luminous intensity distribution section of central luminous intensity distribution section periphery, the led light source assembly is arranged on the lens below, the light middle body that the led light source assembly sends is gone out by the direct transmission of central luminous intensity distribution section, and other light parts in the led light source assembly penetrate via the refraction of side luminous intensity distribution section, another part penetrates behind Multi reflection, because changing direction after refraction or reflection, the light of non-middle position penetrates, scatter so that light can divide more uniformly, realize even light-struck effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Structural representation when Fig. 1 is the utility model application;
Fig. 2 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 1, Fig. 2 is the structural representation of a specific embodiment of the utility model, as shown in the figure, a kind of even optical lens that is applied to the LED light fixture, comprise lens 1, the position is provided with indent spectrum part 11 in the middle of on lens 1, this indent spectrum part 11 includes central luminous intensity distribution section 111, and annular is arranged on the side luminous intensity distribution section 112 of central luminous intensity distribution section 111 peripheries, led light source assembly 2 is arranged on the lens below, the light middle body that led light source assembly 2 sends is gone out by central luminous intensity distribution section's 111 direct transmissions, and other light parts in the led light source assembly 2 penetrate via 112 refractions of side luminous intensity distribution section, another part penetrates behind Multi reflection, because changing direction after refraction or reflection, the light of non-middle position penetrates, so that can dividing more uniformly, light scatters, realize even light-struck effect, wherein the coverage of side luminous intensity distribution section 112 and angle of inclination can be according to the light-emitting area configurations of led light source assembly 2, and can adjust the irradiating angle of whole LED light fixture, applied widely, replacing is installed uses all very convenient.
More than better enforcement of the present utility model is specified, certainly, the utility model can also adopt form different from the embodiment described above, for example: indent spectrum part 11 can be set to one or more as required; So those of ordinary skill in the art should belong in the protection domain of the present utility model the conversion that is equal to of doing under the prerequisite of spirit of the present invention or corresponding the change.
