Embodiment Construction

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] The LED light box of the present invention includes an outer frame of the light box and an LED reflector inside the outer frame, and the LED reflector is composed of a plurality of independently detachable reflector modules. figure 1 It is a schematic cross-sectional view of a reflector module in an LED light box according to an embodiment of the present invention. Each reflector module includes a box body 10, the box body 10 has a transparent front cover 101 and a rear cover 102; at least one reflector 103 is arranged in the box, and the reflective surface of the reflector 103 is in contact with The transparent front cover is opposite; the reflecting plate 103 has a plurality of LED installation parts 104 .

[0016] In another embodiment, the LED reflector module includes a transparent front cover and a back cover; the back cover includes a frame and a reflector...

Abstract

The invention provides an LED lamp box, comprising a lamp box external frame and an LED reflector in the external frame, the LED reflector is formed by a plurality of independently-detachable reflector module groups, each reflector module group comprises a box body, the box body is provided with a transparent front cover and a rear cover; the inner of the box body is provided with at least a reflecting board, the reflecting surface of the reflecting board is opposite to the transparent front cover; and the reflecting board is provided with a plurality of LED installation parts. The LED lamp box is advantageous in that, via the sealed box body, an LED lamp is isolated from the outside world in use, preventing an LED light source from influencing brightness of the lamp box due to adsorbed dust; and the reflector module groups can separate the whole reflecting board into a plurality of module groups for assembly, a single module group is not only advantaged by light weight and small volume, but is also advantaged by accommodation in the box body, even a single person can easily complete installation or maintenance work, particularly for a bottom cover opening or side cover opening type lamp box, assembling and disassembling operations of the module group at the cover opening position can be easily performed in a very small operation space, and the lamp box structure can also make whole light of the lamp box be more uniform.

Description

technical field [0001] The invention relates to the field of a light box light source, in particular to an LED light box. Background technique [0002] Existing LED light boxes, as screen display equipment, often have the problem of poor or uneven brightness, which is related to the structural design of the reflector on the one hand, and to the dust accumulated in the light box on the other hand. Due to the static electricity generated by the LED during use, a large amount of dust is adsorbed on the surface of the LED lamp, which affects the brightness of the light box, and the dust adsorbed on the surface of the LED lamp is not easy to clean. [0003] In addition, most of the existing LED light box reflector boards are a large overall plate structure, which is very inconvenient to install and operate due to their large volume and weight, especially for bottom-opening or side-opening light box structures. At the same time, because the front cover of the light box cannot be ...
