Detailed Description

The following provides a detailed description of the lamp according to the present invention with reference to the accompanying drawings and specific embodiments.

A preferred embodiment of the present application is a wall washer for wall lighting, of which fig. 1 is a structural view of a main body portion thereof, and fig. 2 is a side view of fig. 1. In this embodiment, the lamp body is a strip-shaped lamp body 1, the lamp body 1 has a groove 101 extending in the length direction, a light source mounting surface 6 for mounting the light source module 2 is provided in the groove 101, and the top opening of the groove 101 is a light outlet 7 of the lamp. The main feature of the present application is in the optical design of the polarized light fixture, so that only the fixture and the optical related partial structures are shown in fig. 1 and fig. 2, and in the actual product, the present application may further include end caps disposed at both ends of the lamp body 1, a power driving part disposed inside or outside the lamp body 1, a mounting bracket for mounting the lamp body 1, and these structures have no influence on the main object of the present application, and therefore will not be described in detail in the present application.

The light source module 2 is arranged on the light source mounting surface 6 in the groove 101. In order to prevent the light emitted by the light source module 2 from directly emitting from the light outlet 7, the light source mounting surface 6 is not directly arranged on the inner side wall of the groove 101, but slightly inclines towards the bottom surface of the groove 101, so that an included angle α larger than 90 degrees is formed between the light source mounting surface 6 and the plane of the light outlet 7. The value range of the included angle alpha can be more than or equal to 100 degrees and less than or equal to 130 degrees, preferably more than or equal to 110 degrees and less than or equal to 120 degrees, and the included angle alpha can avoid glare and ensure optical efficiency at the same time.

Since the angle α is larger than 90 degrees, the light-emitting portion of the light source module 2 mounted on the light source mounting surface 6 faces the bottom surface of the groove 101, and in order to make this portion of light available, a reflector 3 is further provided in the groove 101. The reflecting surface 308 of the reflector 3 faces the included angle α, that is, the reflecting surface 308 faces the light source module 2 and the light exit 7 at the same time, and light emitted from the light source module 2 is reflected by the reflector 3 and then 308 exits from the light exit 7. It can be seen from fig. 2 that one end of the reflector 3 starts from the side of the bottom of the groove 101 close to the light source mounting surface 6, and the other end of the reflector 3 ends at a position close to the light outlet 7, and the width of the reflector is approximately equal to the light outlet in the height direction. The emergent light rays formed by reflection of the reflector 3 in the application are not perpendicular to the light outlet 7 and incline to one side, so that the function of the wall washing lamp is realized. In the embodiment of fig. 3, since the wall-washing angle is small, most of the emergent light is inclined at a small angle, so that the wall-washing illumination can be performed on a large range of wall surfaces. In other preferred embodiments, the larger deflection angle may be formed by different reflector designs, which is not limited in this application. In the present embodiment, the reflecting surface 308 of the reflector 3 is a cambered surface and is concave in a direction away from the light source module 2. In order to ensure a good light-emitting effect, the light source module 2 is disposed near the bottom of the groove 101 at a position less than one-half of the height of the reflector, that is, the distance from the light source module 2 to the light-emitting opening 7 is greater than the distance from the light-emitting opening to the bottom of the groove 101. However, at the same time, the light source module 2 should not be too close to the reflector 3, so in the design of the present embodiment, the shortest distance between the light source mounting surface 6 and the reflector 3 is required to be greater than 5mm, preferably 10-20 mm. In other preferred embodiments, the reflecting surface may also be a slope from the light outlet 7 to the bottom surface of the groove 101 or a continuous folding surface according to the light distribution requirement of the lamp.

The reflector 3 may be integrally formed with the lamp body 1 or may be a separate component mounted in the lamp body 1. In this embodiment, the bottom of the groove 101 is provided with a first card slot 302, and the side wall of the groove 101 opposite to the light source mounting surface 6 is provided with a second card slot 301 at a position close to the light outlet 7. The reflector 3 is an arc surface formed by stretching an arc line along the length direction of the lamp, and as can be seen from fig. 2, one end of the side surface of the reflector 3 is inserted into the first slot 302, and the other end is inserted into the second slot 301, so that the reflector 3 is installed and fixed.

Although the included angle α between the light source mounting surface 6 and the light outlet 7 is larger than 90 degrees, most of the light emitted from the light source module 2 will not directly face the light outlet 7, it still cannot be avoided that part of the lateral light of the light source module 2 can leak from the light outlet 7. In order to avoid this, in the present embodiment, the light-shielding portion 5 is further provided on the light source mounting surface 6, the position of the light-shielding portion 5 is located between the light source module 2 and the light outlet 7, and the light-shielding portion 5 is formed as one protrusion extending from the light source mounting surface 6 in the direction of the reflector 3. It can be integrated with the light source mounting surface, and also can be a small baffle plate arranged between the light source module 2 and the light outlet 7. As shown in fig. 3, after the light shielding portion 5 is provided, all the light emitted from the light source module 2 is reflected by the reflector 3 and then emitted from the light outlet 7, so that a good anti-glare effect is achieved.

In addition, in this embodiment, the light outlet 7 of the lamp is further provided with a light-transmitting panel 4, and the light-transmitting panel 4 may be glass or a diffusion plate, which may protect internal devices.

The foregoing description of the preferred embodiments of the invention has been presented for purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously, many modifications and variations may be made which will be apparent to those skilled in the art and are intended to be included within the scope of the invention as defined by the following claims.
