Detailed Description

The invention is further illustrated with reference to the following figures and examples:

the LED lamp comprises an external decorative panel 1, a light hole 1a, a sealant 2, an acrylic light-transmitting plate 3, a light source 4, a screw 5, a cylinder 6, a lamp holder 4a and LED lamp beads 4b

As shown in fig. 1, 2, 3 and 4, the invention discloses an LED diffuse reflection lamp box for an outdoor pedestrian bridge, which comprises an outer decorative panel 1 and a light source 4. The exterior decorative panel 1 is made of a light-tight material, and is generally made of an aluminum gusset plate, a gypsum board or the like for exterior decoration of a building. In the optimized embodiment, the aluminum gusset plates with the thickness of 3mm are arranged on the outdoor pedestrian overpass.

The light source 4 adopts an LED lattice light source. As shown in fig. 4, the light source 4 includes a circular lamp holder 4a, and a plurality of LED lamp beads 4b are mounted on a surface of the lamp holder 4a facing the exterior decoration panel 1. As shown in fig. 1: the exterior decorative panel 1 is provided with a plurality of light holes 1a, and all the light holes 1a are arranged along the panel surface of the exterior decorative panel 1 in an arc shape or a linear shape to form a continuous luminous band and play a role in beautifying.

As shown in fig. 2, a cylinder 6 made of opaque material is correspondingly disposed at each light hole 1 a. In the preferred embodiment, the cylinder 6 is made of high density white PVC. The cylinder 6 was hollow, and the length of the cylinder 6 was 30mm and the wall thickness was 20 mm. One end of the cylinder 6 is sealed and detachably and fixedly connected with the peripheral edge of the light source 4, and the other end of the cylinder 6 is sealed and adhesively fixed with the peripheral edge of the light-transmitting hole 1a, so that light emitted from the light source 4 can only be emitted to the light-transmitting hole 1a along the rotation axis of the cylinder 6.

It should be noted that: the foregoing references to "peripheral edge seal and removably secured" refer to the embodiments shown in fig. 2 and 3: the peripheral edge of the lamp base 4a is aligned with the end face of the cylinder 6 and is connected by means of the screw 5, the connection between the cylinder 6 and the lamp base 4a being free from play and the light does not escape from the connection. The same is true of what is referred to above as "peripheral edge sealing and adhesively securing". The end face of the cylinder 6 is fixedly connected with the plate surface of the outer decorative plate 1 in a gluing and bonding mode, and the sealant 2 fills the connecting gap to enable light rays not to be diffused to the outside of the cylinder 6.

As described above, the light source 4, the cylinder 6 and the exterior decorative panel 1 form an integral structure similar to a lamp box as an exterior decoration of the pedestrian bridge. The light sources 4 do not interfere with each other due to the blocking of the cylinder 6, so that the brightness and color of the light transmitted through each light hole 1a can be displayed according to the construction design.

In this preferred embodiment we have further processed the individual light sources 4. Under general conditions, light emitted by the LED lamp beads 4b is directly projected onto human eyes after being gathered, so that people can feel dazzling and cannot look straight. Due to the particularity of the project, the pedestrian overpass is a building frequently used by people and also belongs to the application in public places. Moreover, the light emitted by the LED lamp beads 4b is also white light. Therefore, in this embodiment, we also perform soft lighting and color changing processing on the light emitted from the light-transmitting hole 1 a.

As shown in fig. 2: a blue acrylic light-transmitting plate 3 is arranged on the end face, close to the light-transmitting hole 1a, of the cylinder 6; the terminal surface of drum 6 inwards caves in and forms the draw-in groove, and this ya keli light-passing board 3 joint is in the draw-in groove of drum 6, and the face of ya keli light-passing board 3 flushes with the terminal surface that drum 6 was equipped with the draw-in groove. The cylinder 6 not only prevents the light sources 4 from interfering with each other, but also serves as a light mixing cavity. The inner wall of the cylinder 6 naturally forms a diffuse reflection cavity (as shown in fig. 3, light emitted by different LED lamp beads 4b is subjected to diffuse reflection), and the light is reflected out through the blue acrylic light-transmitting plate 3 after being subjected to multiple times of diffuse reflection by the inner wall of the cylinder 6, so that the dazzling light directly emitted by the LED is eliminated, and the soft light effect is achieved. And after being refracted by the blue acrylic light-transmitting plate 3, the light is converted into blue light from white light. Of course, also can adopt the ya keli light-passing board 3 of other colours, cooperate different colours LED lamp pearl 4b to make up to realize the soft light effect of different colours. The principle is the same.

Aiming at the particularity of the project, the scheme adopts the blue acrylic light-transmitting plate 3 with the thickness of 3 mm. The reason why the cylinder 6 is bonded to the exterior panel 1 is to eliminate structural impact on the exterior panel 1, maintain the integrity of the appearance of the exterior panel 1, and facilitate mounting. The lamp holder 4a is detachable from the cylinder 6 during use, which also facilitates the replacement of the light source 4.

The above description is only exemplary of the present invention and should not be taken as limiting, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
