It will be understood that the principle of operation of the reflector is as follows:
the reflector provided by the application is used for being installed in the shell 300 of the lamp to reflect the light emitted by the light source, so that the light of the lamp can be emitted in a directional mode. When the reflector is mounted in the housing 300 of the luminaire, the light source is mounted in the reflective cavity 1201 with the reflective wall surrounding the periphery of the light source. After light emitted by the light source enters the lens 200 for refraction, the light with a large angle can be projected onto the convex structure 1202 and is reflected outwards by the convex structure 1202, so that the luminous flux within a range of a large angle (as gamma is 80-90 degrees in fig. 10) is reduced, the light is formed to form light interception distribution after being emitted from the lamp, and glare is avoided. The mounting platform 130 is attached to the housing 300 of the lamp to fix the reflective wall inside the lamp housing 300, and the locking structure 110 can cooperate with the lens 200 covering the light source to fix the position of the reflector in the lamp and prevent the reflector from shifting.
In the prior art, general reflectors are arranged to be smooth reflecting surfaces, such reflectors control the exit angle of emitted light rays by the slope of the reflecting wall, but the slope of the reflecting wall is set to be random and large, and often when the thickness requirement of a lamp is met, the slope of the reflecting wall is set to be small, so that the thickness of the lamp is smaller, but when the reflected light rays are transmitted to the light exit lens 400 of the lamp by the reflecting wall with small slope, the incident angle on the light exit lens 400 is larger than the critical angle of refraction, so that the light rays are totally reflected at the light exit lens 400, the light rays cannot exit, and the light utilization rate of the lamp is low; if the slope of a reflection wall is set to be larger, longitudinal distribution of light distribution is changed from medium projection to short projection, so that the range of the lamp is greatly shortened, and the occupied space height of the reflection wall is higher due to the larger slope, so that the thickness of the lamp is larger, and the miniaturization of the lamp is not facilitated.
The reflector provided by the embodiment of the application at least has the following technical effects:
this application is through setting up protruding structure 1202 at the reflection wall, and protruding structure 1202 sets up on the side of reflection wall orientation reflection chamber 1201, on the basis that does not change the slope of reflection wall, the light source that makes the light source launch can be through protruding structure 1202 external reflection, when having realized not increasing the thickness of lamps and lanterns, can reduce the light flux of light in the wide-angle region, when making light from the inside external emission of lamps and lanterns, can form the cut-off distribution, satisfy the requirement of cut-off lamps and lanterns, the glare phenomenon has been avoided, can protect eyesight, the illuminating effect has been improved.

It can be understood that, in the cross section of each convex structure 1202 on the same plane, the tangential slopes at the thickest point are all equal, that is, the thickness of the thickest point of each convex structure 1202 on the same plane is all the same, so that after the light is emitted from the lens 200, the light with different divergence angles can be transmitted to the convex structures 1202 distributed along the reflecting wall, the specifications of the convex structures 1202 on the same plane are the same, so that the light can be uniformly distributed after being reflected by different convex structures 1202 on the same plane, and can be emitted outwards, thereby improving the illumination effect.

As shown in fig. 1 to 6, as a further technical solution of this embodiment, a slope k of a tangent line at a thickest point of each of the convex structures 1202 on the third reflective wall 1233Satisfies the following conditions: k is more than or equal to 0.1763Less than or equal to 0.30. Specifically, k3Can be set to be 0.176, 0.18, 0.19, 0.20, 0.30 and the like according to the light distribution requirement. Slope k at this range3On the premise of not changing the longitudinal and/or transverse light distribution of the lens 200, glare can be reduced, the problem that light cannot be emitted due to the fact that the incident angle of the light entering the light emitting lens 400 after being reflected is too large can be avoided, and the light utilization rate is improved.
