As shown in fig. 1 to 3, a compound light-gathering device includes a light-emitting source 1, a light-gathering cup 2 and an optical lens 3, wherein the light-emitting source 1 and the optical lens 3 are respectively disposed at two ends of the light-gathering cup 2; the optical lens 3 includes a circular diffractive optical portion 31 located in the middle of the optical lens 3 and a planar light-transmitting portion 32 surrounding the diffractive optical portion 31.
Specifically, the compound light-gathering device of the present embodiment has the following effects:
The problem of device light efficiency utilization ratio low is solved: because the light efficiency utilization rate under the traditional condition is low, the composite light condensing device of the embodiment is provided with the light emitting source, the light condensing cup and the optical lens, the optical lens comprises the circular diffraction optical part and the plane light-transmitting part surrounding the periphery of the diffraction optical part, one part of irradiation light emitted by the light emitting source is refracted by the diffraction optical part and then emitted vertically, and the other part of the irradiation light is reflected by the light condensing cup and then emitted from the plane light-transmitting part, so that the light efficiency utilization rate is improved, and the illumination intensity emitted by the composite light condensing device of the embodiment is increased.
In actual use, in order to achieve a better light-gathering effect, the center of the light-emitting source 1 coincides with the center of the opening at one end of the light-gathering cup 2, and the center of the diffractive optical part 31 coincides with the center of the opening at the other end of the light-gathering cup 2.
The embodiment also discloses a light distribution method of the compound light-gathering device, the light-emitting source 1 emits illumination light, the illumination light comprises a b1 light path 41, a b2 light path 42 and a b3 light path 43, and the method comprises the following steps:
step a, the b1 light path 41 is emitted from the light source 1, directly irradiated to the diffractive optical part 31 without being refracted by the light-condensing cup 2, and emitted after being refracted by the diffractive optical part 31;
B, the b2 light path 42 is emitted from the light source 1, directly irradiates to the plane transparent part 32 without being refracted by the light-gathering cup 2, and directly passes through and emits from the plane transparent part 32;
And c, the b3 light path 43 is emitted from the light source 1, refracted by the light collecting cup 2, irradiated to the plane transparent part 32, and directly emitted from the plane transparent part 32.
The b1 light path 41 is refracted by the diffractive optical part 31 and then emitted vertically.
In a preferred embodiment, the b1 optical path 41 is refracted by the diffractive optical part 31 and then emitted vertically, and the b3 optical path 43 is emitted from the light source 1, refracted by the condenser cup 2, and then emitted vertically to the planar transparent part 32, and then perpendicularly penetrates through the planar transparent part 32.
In the above solution, the cross-sectional view of the compound light-gathering device is shown in fig. 2; the both ends of spotlight cup 2 are equipped with the opening respectively, and the opening area of this one end of light emitting source 1 is littleer than the opening area of this one end of optical lens 3, just so set up can make the light that shines that light emitting source 1 sent shoot out from optical lens 3 after the inside wall refraction of spotlight cup 2.
Referring to fig. 4, 5, 6 and 7, it can be seen that the light effect that the light condensing device can actually utilize is only the illumination light vertically emitted from the opening at one end of the light condensing cup 2, but the illumination light that is not vertically emitted from the opening at one end of the light condensing cup 2 cannot be counted and utilized as the light emitting light effect; that is, the more the irradiated light vertically emitted from the opening at one end of the light-gathering cup 2, the higher the light efficiency utilization rate of the device. The light of the b3 light path 43 is refracted by the inner side wall of the light-gathering cup 2 and then directly emitted out through the plane light-transmitting part 32 to form a first light path; the light path b1 emitted by the light source 1, which is originally free-scattered and wasted light that cannot reach the target, is refracted by the diffractive optical part 31 to form a second light path; the light rays of the first light path and the second light path are not influenced with each other and are overlapped with each other to form a high-brightness light spot, so that high efficiency and energy conservation are realized; relatively speaking, the b2 light path 42 emitted from the light source 1 is directly irradiated to the planar light-transmitting portion 32 without being refracted by the light-collecting cup 2, and the light effect of this portion cannot be utilized, but the light path portion that can be effectively utilized is much larger than the light path of this portion.
As a preferred embodiment, referring to fig. 1, the diffractive optical part 31 is one or more of a fresnel lens, a convex lens and a matrix lens, and other optical materials capable of changing the emitting angle of the parallel light rays besides the fresnel lens, the convex lens and the matrix lens belong to the scope of the present embodiment, and are not described herein again.
As a preferred embodiment, referring to fig. 2, the illumination light of the light source 1 is reflected by the inner sidewall of the light-collecting cup 2 and then passes through the planar light-transmitting portion 32 at the periphery of the diffractive optical portion to be emitted. Since the angle of the irradiation light emitted from the central point of the light source 1 and the distances between the light source 1, the light collection cup 2 and the optical lens 3 can be obtained by measurement or calculation, the slope of the inner sidewall of the light collection cup 2 is determined according to the depth of the light collection cup 2 and the maximum irradiation angle range of the light source 1, and the specific parameters and measurement mode are very conventional for those skilled in the art, and belong to the prior art, and are not described herein again.
As a preferred embodiment, the maximum illumination angle of the illumination source 1 is a1 °, the range of a1 ° of the maximum illumination angle is 60 ° to 360 °, the maximum illumination angle range of the illumination source 1 is generally determined according to the application of the light collecting device of the present embodiment, and the illumination angle of some spherical light sources can reach 360 °. The irradiation light of the maximum irradiation angle of the light source 1 is irradiated to the inner side wall of the light collection cup 2 and forms an A surface 44 tangent to the light collection cup 2, and the diameter of the A surface 44 is not larger than that of the diffraction optical part 31. Since the maximum irradiation angle of the light emission source 1 determines the size of the a-plane 44, the smaller the maximum irradiation angle of the light emission source 1, the larger the area of the a-plane 44, and the narrower the b3 optical path 43, and the smaller the diameter of the necessary diffractive optical portion 31; similarly, the larger the maximum irradiation angle of the light emission source 1, the smaller the area of the a-plane 44, and the wider the b3 optical path 43, and the larger the diameter of the diffraction optical part 31 is required.
In addition, in the specific light intensity simulation diagrams of the present embodiment, the light intensity simulation diagram of the light source 1 and the light collecting cup 2, the light intensity simulation diagram of the light source 1 and the common optical lens 3, and the light intensity simulation diagram of the light source 1, the light collecting cup 2 and the common optical lens 3, reference may be made to fig. 7 to 11, where the light intensity unit of the light source 1 is unified as the light flux; after software simulation, the maximum light intensity in fig. 9 is in the range of about 1.8E +005, the maximum light intensity in fig. 10 is in the range of about 1.05E +005, the maximum light intensity in fig. 11 is in the range of about 1.1E +005 and 1.15E +005, and the maximum light intensity in fig. 12 is in the range of about 1.25E + 005; therefore, the result calculated by the simulation software can be used for concluding that the light intensity of the scheme is far greater than that of the traditional three combinations, and the improvement effect of more than 1.5 times can be achieved (the light effect is related to the size of the maximum illumination angle of the light emitting source 1, and the smaller the maximum illumination angle, the larger the light effect is improved).
In summary, the composite light condensing device and the light distribution method thereof of the embodiment separate the illumination light of the light emitting source 1 into three light paths b1, b2 and b3, and configure different light emitting modes for each light path, so as to achieve better light emitting efficiency, and solve the problem of low light efficiency utilization rate of the conventional light condensing device.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
