Problems solved by technology

[0002] There are two main types of traditional light boxes, one is an internal light box with daylight as the light source, and the other is a surface light box with an organic combination of LED and acrylic light guide plate. High, complex maintenance, high maintenance costs, the latter light box gradually replaces the traditional fluorescent tube light box with its advantages of uniform light emission, energy saving, long life, maintenance-free, etc., but this light box also has shortcomings, due to acrylic The material properties of the light guide plate limit the maximum size of the light guide plate. In addition, the production equipment and transportation conditions also restrict the size of the light guide plate, which makes it impossible to produce large-format light guide plates, and thus cannot make large-format LED light boxes.

Embodiment 1

[0019] The large-format LED light box of this embodiment includes a metal frame 1 and a light guide plate 16. The light guide plate 16 is formed by splicing and combining a plurality of light guide units 7, and grooves 17 are arranged on both sides of each light guide unit 7. The slot 17 is embedded with an LED light strip 10, and the corner of each light guide unit 7 is fixed on the wall 2 with the first fixing screw 5, and the part where the first fixing screw 5 goes deep into the wall 2 is covered with an expansion tube 8 , the metal frame 1 is arranged around the light guide plate 16, the metal frame 1 is fixed on the wall 2 by the second fixing screw 3, the metal frame 1 is provided with a transformer adapter 4 and a movable pendant 15, and the transformer adapter 4 is bonded On the metal frame 1, the groove of the movable pendant 15 is connected with the protruding part of the metal frame 1. The movable pendant 15 is provided with a fixed rod 14, and the light box cloth 9...

Embodiment 2

[0022] The difference between this embodiment and Embodiment 1 is that the distance between the light box cloth 9 and the light guide plate 16 is 35 mm.

Embodiment 3

[0024] The difference between this embodiment and Embodiment 1 is that the distance between the light box cloth 9 and the light guide plate 16 is 50 mm.

[0025] The LED light boxes of the above embodiments solve the problem that large-format light boxes cannot be produced in the prior art by splicing single small-area light guide units into required large-format light guide plates. A single small-area light guide unit can be transported to the site for on-site installation and construction, which is very convenient for transportation and construction, and the transformer adapter and movable pendant are installed in the metal frame, which also facilitates daily maintenance and replacement of light boxes It is convenient for deployment and also solves the problem of the storage location of the transformer adapter.

Abstract

The invention relates to an LED (light-emitting diode) lamp box, in particular to a large-area LED lamp box, belonging to the technical field of a lamp box device. The large-area LED lamp box comprises a metal frame and a light guide plate, wherein the light guide plate is formed through assembly of a plurality of light guide units, each light guide unit is provided with a groove, an LED light bar is embedded in each groove, the corners of each light guide unit are fixed on a wall surface through first fixing screws, the parts of the first fixing screws embedded into the wall surface are sleeved in expansion tubes, the metal frame is arranged around the light guide plate, and a transformer adapter and a movable hanging component are arranged in the metal frame. Since the single small-arealight guide units are assembled to form the large-area light guide plate, the problem of the prior art that a large-area lamp box cannot be manufactured can be solved, the daily maintenance and the replacement of lamp box cloth can be facilitated, and the problem of storage of the transformer adapter can also be solved.
