Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 3a to fig. 7, an embodiment of the present invention provides a light distribution device 10, which includes a housing 100, a reflector 200, and a light emitting assembly 300; wherein, the bottom of the housing 100 is provided with a protruding structure 400, and the protruding structure 400 is provided with a mounting surface (including a first inclined surface 410 and a second inclined surface 420 mentioned below), the mounting surface and the bottom surface of the housing 100 form a preset angle, wherein the preset angle is an obtuse angle; the reflector 200 is symmetrically provided with reflective surfaces, the reflective surfaces are arranged around the protrusion structure 400, and the reflective surfaces and the bottom surface of the housing 100 form a preset angle, wherein the preset angle is an obtuse angle; the light emitting assembly 300 is disposed on a mounting surface.

Meanwhile, the light distribution device 10 is not required to be equipped with an optical lens or a grating, but realizes light distribution through the combination of the light emitting assembly 300 and the reflector 200 integrated in the shell 100, thereby solving the problem of low light distribution uniformity caused by low assembly precision of the existing optical lens or grating.

Specifically, as shown in fig. 3a to 3c, when the light emitting assembly 300 is mounted on the mounting surface, the light emitting assembly 300 and the bottom surface of the housing 100 also form a certain angle, so that the light irradiation direction of the light emitting assembly 300 is distributed in the reflector 200 in a set manner, that is, part of the light emitted by the light emitting assembly 300 can be distributed by the reflective surface on the reflector 200 in a secondary reflection manner, so that the light beam after being reflected and refracted by the reflective surface in the reflector 200 and the edge of the reflector 200 have a preset beam angle b of anti-glare, as shown in fig. 7, and at the same time, the finally irradiated light can achieve the light distribution effect of batwing, and the requirement of the use place for light uniformity is met.

Therein, it is understood that an integrated space is provided in the housing 100, and both the light emitting assembly 300 and the light reflector 200 may be provided in the integrated space. The casing may be made of metal, or may be made of other materials with good heat dissipation performance. In addition, the reflector can be formed by plastic molding or metal plate stamping.

Specifically, as shown in fig. 3a to 3c, the mounting surface on the protruding structure 400 includes a first inclined surface 410 and a second inclined surface 420 which are oppositely disposed, and an angle between the first inclined surface 410 and the bottom surface of the housing 100 is equal to or unequal to an angle between the second inclined surface 420 and the bottom surface of the housing 100. When the angle between the first inclined surface 410 and the bottom surface of the housing 100 is equal to the angle between the second inclined surface 420 and the bottom surface of the housing 100, as shown in fig. 3a, the angle ranges of the light beams emitted by the light emitting assemblies 300 on the first inclined surface 410 and the second inclined surface 420 are the same, and the irradiation intensity, the anti-glare beam angle, and the illumination uniformity of the light beam obtained by the reflection and refraction of the reflector 200 are the same, which is suitable for being applied to the directly irradiated illumination position.

When the angle between the first inclined plane 410 and the bottom surface of the housing 100 is greater than the angle between the second inclined plane 420 and the bottom surface of the housing 100, as shown in fig. 3b, the light shape obtained by the light beam emitted by the light emitting assembly 300 on the first inclined plane 410 after being reflected and refracted by the reflector 200 is longer than the light shape obtained by the light beam emitted by the light emitting assembly 300 on the second inclined plane 420 after being reflected and refracted by the reflector 200, and at this time, the light emitting device is suitable for the illumination position with indirect illumination.

It is understood, however, that in some particular applications, the angle between the first inclined surface 410 and the bottom surface of the housing 100 may be smaller than the angle between the second inclined surface 420 and the bottom surface of the housing 100. Thus, by adjusting the mounting of the light emitting assembly 300 to different angled mounting surfaces on the raised structure 400, a batwing beam angle and uniformity of illumination of the illuminated location can be achieved that meets the anti-glare requirements of different applications.
