Abstract

The utility model relates to a light-emitting diode (LED) light bar and belongs to the field of LED display technology. The LED light bar comprises a light holder with an opening at the top, end covers are respectively and fixedly connected with two ends of the light holder, the light holder is fixedly connected with a shell, and a light panel is arranged inside the lamp holder. A set of luminescent device is arranged on a side of the light panel near the shell, and a light hole matching with the luminescent device is arranged in the shell. At least one glue-filling hole is arranged in the light panel, and sealant-filling layers are respectively arranged between the light panel and the shell and between the light panel and the light holder. By means of the structure, only once sealant-filling is needed in the process of installation, and therefore the LED light bar is beneficial to improve production efficiency.

Description

A kind of LED lamp bar

Technical field

The utility model relates to a kind of LED lamp bar, is particularly useful for the open air, belongs to LED Display Technique field.

Background technology

At present, the LED display industry competition is fierce day by day, and production efficiency becomes one of aspect of competition.Improving production efficiency of products and not only can improve delivery rate, also is that great help is arranged for reducing production cost of products.

LED lamp bar is the basic composition unit of LED curtain wall display screen, and the height of its production efficiency has directly had influence on the production efficiency of curtain wall screen.Usually, need lamp plate (or printed board, face battle array drive plate) the positive and negative encapsulating respectively at LED lamp bar, just there is following problem in this: (1) needs operating personnel to do twice encapsulating work, and workload is bigger; (2) need expend the long period and wait for that glue is air-dry; (3) need earlier this face to be inverted at encapsulating of lamp plate, and to lamp plate another side encapsulating again, in case that glue allocate was rare, causes being inverted face glue easily and spill, polluted product is surperficial; (4) owing to pour into glue respectively on the two sides; After treating that glue parches the formation glue-line; The glue-line on two sides can form contact-making surface at the lamp plate edge, LED lamp bar tends to occur the poorly sealed situation of above-mentioned contact-making surface through long-time outdoor use; It is inner to cause steam to be prone to get into the lamp bar from this contact-making surface, damages LED lamp bar.

The utility model content

The purpose of the utility model is: the problem to above-mentioned prior art exists, only need encapsulating LED lamp bar once when proposing a kind of the installation, and help enhancing productivity.

In order to reach above purpose, the technical scheme of the utility model is following:

A kind of LED lamp bar comprises open-topped lamp socket, it is characterized in that, said lamp socket two ends are fixed with end cap respectively, and said lamp socket and face shield are connected and positioned inside has lamp plate; Said lamp plate has one group of luminescent device near the side of face shield, and said face shield has the lamp hole that matches with luminescent device; Said lamp plate has at least one glue filling opening, is respectively equipped with the embedding glue-line between said lamp plate and the face shield and between said lamp plate and the lamp socket.

During installation, lamp plate is placed in the lamp socket, end cap is contained in the lamp socket two ends; Through the glue filling opening encapsulating, make between lamp plate and the lamp socket to be full of glue, continue encapsulating then and overflow to concordant with lamp socket top sides edge until glue; Face shield is contained in the lamp socket top, treats that glue parches to get final product.

After adopting the utility model structure, only need encapsulating once during installation, help enhancing productivity.

The specific embodiment

Embodiment

Present embodiment LED lamp bar basic structure such as Fig. 1 are to shown in Figure 4; Comprise the lamp socket of processing by aluminium section bar 1; Lamp socket 1 two ends are connected through screw fastener and end cap 2 respectively; Lamp socket 1 open top also is connected through screw fastener and face shield 3, and lamp socket 1 bottom is provided with the through hole 1-1 that supplies cable 4 to pass, and lamp socket 1 positioned inside has lamp plate 5; Lamp plate 5 has one group of luminescent device 5-1 near the side of face shield 3, and lamp plate 5 is electrically connected with cable 4 away from the side of face shield 3, and lamp plate 5 has at least one glue filling opening 5-2 (more even for making encapsulating, that more glue filling opening can be set as required); Be respectively equipped with embedding glue-line 6-1 and 6-2 between lamp plate 5 and the face shield 3 and between lamp plate 5 and the lamp socket 1; Face shield 3 has the lamp hole 3-2 that matches with luminescent device 5-1.

Face shield 3 is provided with in order to the eaves board 3-1 that blocks sunray and in order to the band 3-3 of the extraneous light of diffuse reflection away from the side of lamp socket 1.

During installation, lamp plate 5 is placed in the lamp socket 1, end cap 2 is contained in lamp socket 1 two ends; Through glue filling opening 5-2 encapsulating, make between lamp plate 5 and the lamp socket 1 to be full of glue, continue encapsulating then, overflow to concordant until glue with lamp socket 1 top sides edge; Face shield 3 is contained in lamp socket 1 top, treats that glue parches to get final product.

Compared with prior art, present embodiment has the following advantages: (1) only needs encapsulating once when installing, and obviously reduces workload; (2) can after installation, place wait glue and parch, practice thrift the set-up time greatly; (3) no longer need during encapsulating to be inverted, effectively avoid glue polluted product surface; (4) glue once irritates, and can avoid forming the glue-line contact-making surface, thereby prevent that effectively steam water inlet lamp bar is inner.

Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
