The point light source integrated light concentrating assembly and the lamp thereof according to the embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1 to 3, a point light source integrated light concentrating assembly according to an embodiment of the present invention includes an outer reflector 10 and an inner reflector 20.
Specifically, the outer reflection housing 10 has a light inlet H10, a light outlet H11, and an accommodation space P10, the light outlet H11 is opposite to the light inlet H10 and is communicated with the accommodation space P10, and an inner surface of the accommodation space P10 includes a first reflection surface S10 and a second reflection surface S11 sequentially arranged from the light outlet H11 to the light inlet H10.
In the example shown in fig. 2 and 3, the light inlet H10 is located below the accommodating space P10, and the light outlet H11 is located above the accommodating space P10 and opposite to the light outlet H11. The inner surface of the accommodating space P10 includes a first reflective surface S10 and a second reflective surface S11, the first reflective surface S10 is adjacent to the light exit H11, and the second reflective surface S11 is adjacent to the first reflective surface S10. When the light condensing assembly is specifically applied to a lamp, the point light source 30 may be disposed at the light inlet H10, for example, the point light source 30 is disposed at a predetermined position below the light inlet H10, or the point light source 30 is disposed at the light inlet H10, or it may be disposed at a predetermined position above the light inlet H10 in the accommodating space P10, so that the light emitted by the point light source 30 is incident into the outer reflective cover 10 from the light inlet H10.
The inner reflector 20 is disposed in the accommodating space P10 and is fixedly connected to the outer reflector 10 through a connecting member 201, the inner surface of the inner reflector 20 is a central reflecting surface S20, and the central reflecting surface S20 faces the light inlet H10. That is, the inner reflector 20 is located in the accommodating space P10 and opposite to the light inlet H10, and the inner reflector 20 is connected to the outer reflector 10 through the connecting member 201, so that the inner reflector 20 and the outer reflector 10 are relatively fixed. Further, the inner surface of the inner reflection cover 20 faces the light entrance H10, and serves as a central reflection surface S20.
A part of light entering the light inlet H10 is reflected by the first reflecting surface S10 and then exits from the light outlet H11, and another part of light entering the light inlet H10 is reflected once by the central reflecting surface S20 to the second reflecting surface S11, and is reflected twice by the second reflecting surface S11 and then exits from the light outlet H11.
Since the inner reflector 20 is opposed to the light inlet H10 in the outer reflector, the light rays closer to the optical axis among the light rays of the point light source 30 are emitted toward the central reflecting surface S20 of the inner reflector 20, are once reflected to the outer second reflecting surface S11 by the central reflecting surface S20 of the inner reflector 20, are twice reflected by the second reflecting surface S11, and are emitted from the light outlet H11. The light beams from the two sides of the point light source 30 away from the center of the optical axis directly strike the first reflecting surface S10 of the outer reflector, and are reflected by the first reflecting surface S10 and then exit from the light exit H11.
The distance between the inner reflector 20 and the light inlet H10 in the outer reflector 10 can be adjusted as needed as long as the light near the optical axis of the point light source 30 can be reflected by the central reflecting surface S20 of the inner reflector 20 and then reflected by the first reflecting surface S10 of the outer reflector 10. At the same time, it is sufficient to ensure that the light rays on both sides of the optical axis of the point light source 30 can be reflected by the second reflecting surface S11 of the outer reflection cover 10.
According to the point light source integrated light condensing assembly provided by the embodiment of the invention, the point light source integrated light condensing assembly comprises an outer reflector 10 and an inner reflector 20, the outer reflector 10 is provided with a first reflecting surface S10 and a second reflecting surface S11, the inner reflector 20 is provided with a central reflecting surface S20, a part of light incident from a light inlet H10 is reflected by the first reflecting surface S10 and then emitted from a light outlet H11, the other part of light incident from a light inlet H10 is reflected to the second reflecting surface S11 once by the central reflecting surface S20 and then emitted from the light outlet H11 after being reflected twice by the second reflecting surface S11, so that effective light can be condensed into effective light spots through the matching of the outer reflector 10 and the inner reflector 20, the light emitted after reflection is more uniform, and the brightness of the point light source is uniform. In addition, the inner reflector 20 is fixedly connected with the outer reflector 10 through the connecting piece 201, so that the inner reflector 20 and the outer reflector 10 can be relatively fixed, the coaxiality is high, the stability is good, and the assembly in the lamp is facilitated.
Referring to fig. 3, in an embodiment of the present invention, a connecting member 201 is formed in a rib shape, one end of the connecting member 201 is connected to the periphery of the inner reflector 20, and the other end of the connecting member 201 extends toward the outer reflector 10 and is connected to the outer reflector 10, so that the rib-shaped connecting member 201 can be used to connect and fix the inner reflector 20 and the outer reflector 10. Moreover, the area of the rib-shaped connecting piece 201 is small, the shielding loss of light is reduced, and the light utilization rate is improved.
In addition, preferably, the other end of the connecting part 201 is connected to the edge of the light inlet H10, so that the projection area of the connecting part 201 on the plane where the light outlet H11 is located can be smaller, and the shielding loss of the connecting part 201 to light rays can be further reduced as much as possible.
Advantageously, the connecting member 201 is plural, and a plurality of the connecting members 201 are arranged at intervals along the circumference of the inner reflector 20. In the example of fig. 3, three connecting members 201 are provided, and the three connecting members 201 are arranged on the periphery of the inner reflector 20 at equal intervals, so that the inner reflector 20 and the outer reflector 10 can be fixed more firmly and reliably by using a plurality of connecting members 201.
More advantageously, the connecting member 201, the inner reflector 20 and the outer reflector 10 are integrally formed, so that the inner reflector 20 and the outer reflector 10 are conveniently formed in one step, and the formed inner reflector 20 and the formed outer reflector 10 are stable and reliable in structure, high in coaxiality, and good in consistency of products processed in batches.
Referring to fig. 3, in the preferred embodiment of the present invention, the outer reflector 10, the inner reflector 20, the light inlet H10 and the light outlet H11 have the same axis, and the first reflecting surface S10, the second reflecting surface S11 and the central reflecting surface S20 surround the axis. That is, the outer reflector 10 and the inner reflector 20 are both formed in a solid of revolution structure, and in the example of fig. 1, the outer reflector 10 is formed in a gradually changing trumpet shape, and the inner reflector 20 is formed in a conical shape, that is, the longitudinal cross section of the inner reflector 20 is V-shaped. When the point light source 30 is installed, the optical axis of the point light source 30 coincides with the axis, so that the light condensing assembly can converge all effective light rays of the light source into the design range of effective condensing light spots, all light rays of the light source can be effectively utilized, and the utilization rate of the light source is improved.
It should be noted that, the curvatures of the first reflecting surface S10 and the second reflecting surface S11 can be adjusted to further change the light emitting angle and the light emitting spot shape, for example, the curvatures of the first reflecting surface S10 and the second reflecting surface S11 are adjusted to make all the light rays emitted from the light outlet H11 parallel to the optical axis or form a certain angle with the optical axis. Of course, in other embodiments, the converging light-emitting spot effect and the light-emitting angle may also be corrected by adjusting the position of the point light source 30 in the vertical direction or changing the size of the light spot of the point light source 30.
It can be understood that the first reflective surface S10, the second reflective surface S11, and the central reflective surface S20 may be curved surfaces, or inclined surfaces, and the curved surfaces, or inclined surfaces may be selected according to the light-emitting angle and the light-emitting spot requirement.
Advantageously, the diameters of the first reflecting surface S10 and the second reflecting surface S11 gradually increase from bottom to top, and the slope of the generatrix on the first reflecting surface S10 is greater than the slope of the generatrix on the second reflecting surface S11. That is, each of the first and second reflecting surfaces S10 and S11 is formed in a horn shape gradually expanding from bottom to top, and a slope of a generatrix on the first reflecting surface S10 is larger than a slope of a generatrix on the second reflecting surface S11, where the generatrix is a slope of a tangent to the generatrix on a curved surface or a cambered surface when the first and second reflecting surfaces S10 and S11 are curved surfaces or cambered surfaces, and the slope is a slope of the generatrix itself on a slope when the first and second reflecting surfaces S10 and S11 are sloped surfaces.
In this way, the generatrix on the second reflecting surface S11 has a small slope with respect to the generatrix on the first reflecting surface S10, so that the light reflected by the central reflecting surface S20 of the inner reflecting cover 20 can be secondarily reflected by the second reflecting surface S11 to be collimated and emitted from the light outlet H11. The generatrix on the first reflecting surface S10 has a larger slope than the generatrix on the second reflecting surface S11, so that the light rays at two sides of the point light source 30 away from the optical axis can be directly reflected by the first reflecting surface S10 to form parallel light rays and be emitted from the light outlet H11, and further the emitted light rays are more uniform, and the uniformity of the brightness is improved.
More advantageously, the central reflecting surface S20 is conical and gradually decreases in diameter from bottom to top. Thus, the conical central reflecting surface S20 can ensure that all the light rays projected thereon can be reflected to the second reflecting surface S11, thereby improving the utilization rate of the light rays.
It is understood that, of course, in order to utilize the reflection efficiency of the inner reflector 20, it is preferable that the projected area of the central reflecting surface S20 on the plane of the light inlet H10 is substantially equal to the area of the light inlet H10.
Referring to fig. 1 to 3, a lamp according to an embodiment of the present invention includes a point light source 3030 and a point light source integrated light-focusing assembly as described in the above embodiments, wherein the point light source 30 is disposed at the light inlet H10, and the specific structure and the operation principle of the point light source 30 split light-focusing assembly are described in the above embodiments, and are not described herein again.
The lamp in the embodiment has a good light-gathering effect, and can be applied to occasions with high light intensity requirements, such as a remote highlight flashlight, a submarine light, a searchlight and the like.
According to the lamp provided by the embodiment of the invention, the point light source integrated light condensation component is provided, so that the effective light rays of the point light source 30 can be converged into effective light spots through the matching of the outer reflector 10 and the inner reflector 20, the light condensation effect and the light source utilization rate are improved, and meanwhile, the emergent light rays after reflection are more uniform, so that the brightness is uniform. In addition, the inner reflector 20 is fixedly connected with the outer reflector 10 through the connecting piece 201, so that the inner reflector 20 and the outer reflector 10 can be relatively fixed, the coaxiality is high, the stability is good, and the assembly in the lamp is facilitated.
