Description

A strip lamp housing

[technical field]

The invention relates to a strip lamp housing.

[Background technique]

LED is a semiconductor that can convert electrical energy into light energy. LED lights have the advantages of long life, high luminous efficiency, no radiation, and low power consumption. More and more applications are now using LED lights for lighting.

The thickness of the existing lamp shell is uniform, which is used to make the illuminant of the rear lamp evenly transmit light, but its scattering angle is small and the illumination area is small.

[Content of the invention]

The present invention overcomes the disadvantages of the above-mentioned technologies, and provides a strip-shaped lamp housing, which has a simple structure and is easy to implement, and effectively increases the scattering angle to increase the illumination area.

To achieve the above object, the present invention adopts the following technical solutions:

A strip-shaped lamp housing, including a strip-shaped lamp housing body 1, the rear side of the strip-shaped lamp housing body 1 is provided with an inner groove 11 for the light of the light emitter behind it to enter into it, and the inner groove 11 The length direction is consistent with the length direction of the strip-shaped lamp housing body 1, and the front side of the strip-shaped lamp housing body 1 corresponding to the inner groove 11 is provided with an outwardly convex arc-shaped surface 12, and the upper and lower sides of the inner groove 11 A first vertical wall surface 111 is respectively provided, and a second vertical wall surface 121 is respectively provided on the upper and lower sides of the convex arc surface 12, and the first vertical wall surface 111 and the second vertical wall surface 121 are parallel to each other, so The vertical span of the convex arc surface 12 is greater than the vertical span of the inner groove 11 .

As for the above-mentioned strip-shaped lamp housing, the strip-shaped lamp housing body 1 behind the first vertical wall 111 is also provided with a mounting bracket for cooperating with the first vertical wall 111 so as to fix the lamp illuminant. Several elastic hooks 7.

In the above-mentioned strip-shaped lamp housing, the thickness between the outer convex arc surface 12 and the inner groove 11 is relatively thin in the middle and relatively thick at the upper and lower sides.

Compared with prior art, the beneficial effect of the present invention is:

1. In this case, an outwardly convex arc-shaped surface is provided on the front side of the lamp housing body corresponding to the inner groove. The upper and lower spans of the inner groove are larger than the upper and lower spans of the inner groove, so that the light entering the inner groove is scattered to the range of the outer convex arc surface, and the side leakage is small, and then the light is increased through the outer convex arc surface for the second time. Large light scattering angle, effectively increasing the scattering angle for wide-area lighting.

2. The bar-shaped lamp housing body behind the first vertical wall is also equipped with several elastic hooks for cooperating with the first vertical wall to fix the lamp illuminant, so that the plate-shaped lamp is easy to emit light The body is fixed between the first vertical wall and the elastic hook.

3. The thickness between the convex arc surface and the inner groove is relatively thin in the middle and relatively thick on the upper and lower sides. In this way, the light intensity is not concentrated in the middle area while increasing the light scattering area, so as to facilitate Uniform glow.

[detailed description]

The features of the present invention and other related features will be further described in detail below in conjunction with the accompanying drawings through embodiments, so as to facilitate the understanding of those skilled in the art:

As shown in Figures 1-3, a strip-shaped lamp housing includes a strip-shaped lamp housing body 1, and the rear side of the strip-shaped lamp housing body 1 is provided with a concave cavity for the light of the light emitter behind it to enter. Groove 11, the length direction of the inner groove 11 is consistent with the length direction of the strip lamp housing body 1, and the front side of the strip lamp housing body 1 corresponding to the inner groove 11 is provided with a convex arc surface 12, The upper and lower sides of the inner groove 11 are respectively provided with a first vertical wall surface 111, and the upper and lower sides of the outer convex arc surface 12 are respectively provided with a second vertical wall surface 121, and the first vertical wall surface 111 is connected with the second vertical wall surface. The vertical walls 121 are parallel to each other, and the vertical span of the convex arc surface 12 is larger than the vertical span of the inner groove 11 .

As mentioned above, in this case, a convex arc surface is provided on the front side of the lamp housing body corresponding to the inner groove. The upper and lower spans of the shaped surface 12 are greater than the upper and lower spans of the inner groove 11, so that the light entering the inner groove is scattered to the range of the outer convex arc surface 12, and the side leakage is small, and then passes through the outer convex arc. The surface increases the scattering angle of light for the second time, effectively increasing the scattering angle to increase the illuminated area.

As mentioned above, during specific implementation, the bar-shaped lamp housing body 1 behind the first vertical wall 111 is also provided with several elastic clips for cooperating with the first vertical wall 111 to fix the light emitting body. The hook 7 is thus convenient to fix the plate-shaped lamp illuminant between the first vertical wall surface 111 and the elastic hook 7 .

As mentioned above, in actual implementation, the thickness between the convex arc-shaped surface 12 and the inner groove 11 is relatively thin in the middle and relatively thick at the upper and lower sides. The light intensity is not concentrated in the middle area, so that it can emit light evenly.

As mentioned above, what this case protects is a strip-shaped lamp housing, and all technical solutions with the same or similar structure as this case should be deemed to fall within the protection scope of this case.
