The line source split type reflecting component and the lamp thereof according to the embodiments of the present invention are described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, a split type reflector assembly of a line light source 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 two symmetrical sidewalls 101, the light outlet H11 is opposite to the light inlet H10, the two symmetrical sidewalls 101 are located between the light inlet H10 and the light outlet H11, an inner surface of each sidewall 101 includes a first reflection surface S10 and a second reflection surface S11 sequentially arranged from the light outlet H11 to the light inlet H10, and the first reflection surface S10 and the second reflection surface S11 extend along a predetermined direction.

In the example of fig. 3, the light inlet H10 is located below the light outlet H11 and opposite the light outlet H11. The two side walls 101 are located between the light inlet H10 and the light outlet H11, and the two side walls 101 are symmetrically arranged. The inner surface of each side wall 101 includes a first reflection surface S10 and a second reflection surface S11, the first reflection surface S10 is adjacent to the light exit opening H11, the second reflection surface S11 is adjacent to the light entrance opening H10, and the first reflection surface S10 and the second reflection surface S11 extend along a predetermined direction (e.g., a horizontal direction) with the side wall 101. When the reflector assembly is specifically applied to a lamp, the linear light source 30 may be disposed at the light inlet H10, and the length direction of the linear light source 30 is the same as the extending direction of the sidewall 101, for example, the linear light source 30 is disposed at a predetermined position below the light inlet H10, or the linear 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 outer reflector 10, so that the light emitted from the linear light source 30 enters the outer reflector 10 from the light inlet H10.

The inner reflector 20 is disposed inside the outer reflector 10, and the inner surface of the inner reflector 20 includes two symmetrical central reflecting surfaces S20, and the two central reflecting surfaces S20 face the light inlet H10 and extend in the same direction as the first reflecting surface S10 and the second reflecting surface.

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 opposite to the light inlet H10 in the outer reflector 10, the light rays closer to the optical axis surface among the light rays of the linear light source 30 are emitted toward the central reflecting surface S20 of the inner reflector 20, are once reflected to the second reflecting surface S11 of the outer reflector 10 by the central reflecting surface S20 of the inner reflector 20, are secondarily reflected by the second reflecting surface S11, and are emitted from the light outlet H11. The light rays from two sides of the linear light source 30 far from the center of the optical axis face directly irradiate the first reflecting surface S10 of the outer reflector 10, and are reflected by the first reflecting surface S10 and then exit from the light exit H11.

It should be noted that the distance between the inner reflector 20 and the light inlet H10 in the outer reflector 10 can be adjusted as required, as long as it can ensure that the light near the optical axis of the linear light source 30 can be reflected by the central reflecting surface S20 of the inner reflector 20 first, and then reflected by the first reflecting surface S10 of the outer reflector 10. Meanwhile, it is sufficient to ensure that the light on both sides of the optical axis surface of the linear light source 30 can be reflected by the second reflecting surface S11 of the outer reflection cover 10.

According to the utility model provides a split type reflection of light subassembly of line light source has outer bowl 10 and internal reflection cover 20, and lateral wall 101 of outer bowl 10 has first plane of reflection S10 and second plane of reflection S11, and internal reflection cover 20 has two central planes of reflection S20, and some light that light inlet H10 jetted into passes through follow after first plane of reflection S10 reflects light outlet H11 jets out, and another some light that light inlet H10 jetted into passes through central plane of reflection S20 once reflects to second plane of reflection S11, passes through again follow after second plane of reflection S11 secondary reflection light outlet H11 jets out, so, through the cooperation of outer bowl 10 and internal reflection cover 20 both, can assemble line light source 30 effective light into effective facula, improves spotlight effect and light source utilization ratio, in addition, the light that the reflection back emergent is more even, and then make luminance even.

It will be appreciated that the outer reflector 10 may further comprise two end walls 102, the two end walls 102 being connected to two ends of the two side walls 101, respectively, in the example of fig. 1, the two end walls 102 are formed as arc-shaped walls, so that the entire outer reflector 10 is substantially oval-shaped. Of course, the two end walls 102 may also be formed as straight walls, thereby making the entire outer bowl 10 generally rectangular.

Preferably, the two side walls 101 are symmetrical about a first plane of symmetry, and the two central reflecting surfaces S20 are symmetrical about a second plane of symmetry, the first plane of symmetry coinciding with the second plane of symmetry. When the line light source 30 is installed, the optical axis surface of the line light source 30 coincides with the first symmetrical surface and the second symmetrical surface, so that the light reflecting component can converge all effective light rays of the light source into the design range of effective light condensing 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, by adjusting the curvatures of the first reflecting surface S10 and the second reflecting surface S11, all the light rays emitted from the light outlet H11 are parallel to the optical axis plane or form a certain angle with the optical axis plane. Of course, in other embodiments, the converging light spot effect and the light emitting angle may also be corrected by adjusting the position of the linear light source 30 in the vertical direction or changing the size of the light spot of the linear 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 slope of the perpendicular tangent to the first reflecting surface S10 is greater than the slope of the perpendicular tangent to the second reflecting surface S11. The vertical tangent of the first reflecting surface S10 is the intersection between the longitudinal section of the outer reflector 10 and the first reflecting surface S10, and the vertical tangent of the second reflecting surface S11 is the intersection between the longitudinal section of the outer reflector 10 and the second reflecting surface S11. When the vertical tangent is a curve or arc, the slope refers to the slope of the tangent on the curve or arc, and when the vertical tangent is a straight line, the slope refers to the slope of the straight line itself.

In this way, the vertical tangent of the second reflecting surface S11 has a smaller slope than the vertical tangent of the first reflecting surface S10, so that the light reflected by the central reflecting surface S20 of the inner reflection cover 20 can be reflected by the second reflecting surface S11 for a second time to form parallel light and then exit from the light exit H11. The vertical tangent of the first reflective surface S10 has a larger slope than the vertical tangent of the second reflective surface S11, so that the light rays at two sides of the linear light source 30, which are far away from the optical axis surface, can be directly reflected by the first reflective 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 surfaces S20 intersect to form an inverted V shape, so that the central reflecting surfaces S20 of the inverted V shape can ensure that the light projected thereon can be reflected to the second reflecting surface S11, thereby improving the utilization rate of the light.

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 two central reflecting surfaces S20 on the plane of the light inlet H10 is substantially equal to the area of the light inlet H10.

In one embodiment of the present invention, the inner reflector 20 is detachably disposed on the outer reflector. That is, the inner reflector 20 is not directly connected to the outer reflector 10, so that the connection structure between the inner reflector 20 and the outer reflector 10 can be prevented from blocking light to cause light loss, and the light utilization rate can be further improved.

Optionally, the top of the inner reflector 20 has a connecting member 201 protruding toward the light outlet H11, and a central plane of the connecting member 201 coincides with the second symmetric plane. In the example of fig. 1, the connecting member 201 is formed in a plate shape extending upward, and in a specific application, the upper end of the connecting member 201 may be connected to a carrier such as a light-emitting mask, so that the inner reflector 20 and the outer reflector 10 are kept relatively fixed.

In this embodiment, the connecting member 201 is adopted, and on one hand, since the central plane of the connecting member 201 coincides with the second symmetric plane on the internal reflection cover 20, the connecting member 201 does not block light, and light loss is reduced. On the other hand, the connecting member 201 facilitates the installation and fixation of the inner reflection cover 20, and has a simple structure and convenient connection.

It is understood that the specific embodiment of the connecting member 201 can be implemented in various different structures as required, for example, the connecting member 201 can also be a column extending upward, and the number of the columns can be multiple, so as to ensure that the inner reflector 20 is more stable when being fixed to the light-emitting mask.

Referring to fig. 1 to 4, according to the embodiment of the present invention, the lamp includes a linear light source 30 and the split-type reflective assembly of linear light source as described in the above embodiments, wherein the linear light source 30 is disposed at the light inlet H10, and the specific structure and the working principle of the split-type reflective assembly of linear light source are described in the above embodiments, which are not repeated herein.

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 utility model provides a lamps and lanterns have the split type reflection of light subassembly of above-mentioned line source, consequently, through the cooperation of outer bowl 10 with the internal reflection cover 20 both, can assemble into effective facula with the effective light of line source 30, improve spotlight effect and light source utilization ratio, in addition, the light of outgoing after the reflection is more even, and then makes luminance even.
