In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be described in more detail below with reference to the drawings and examples. The specific examples described herein are merely for the purposes of interpreting the present application and are not limiting of the present application.

A lens plate 110 according to an embodiment of the present application will be described with reference to FIGS. 1 to 9. First locking members 120 are installed on both ends of the lens plate 110, respectively. The first locking device 120 includes a locking portion 121 that detachably locks the lens plate 110 to the base 200 of the ceiling light and a connecting portion 122 that connects the locking portion 121 and the lens plate 110. .. The connecting portion 122 has a U-shaped structure with an opening facing downward.

When used, the base 200 is provided with a first through hole 210 penetrating the base 200 and passing the first locking member 120. When assembling the ceiling light, the lens plate 110 and the light source substrate 140 are assembled to form the light source unit 100, and the locking claws of the first locking member 120 are passed through the first through holes 210 to form the outer wall of the base 200. The light source unit 100 is installed on the base 200 so as to be locked.

When the light source unit 100 has a failure, an action force for detaching the first locking member 120 from the base 200 is applied to separate the light source unit 100 and the base 200, so that the corresponding component in the light source unit 100 The entire light source unit 100 is replaced.

Compared with the prior art, the lens plate 110 according to the embodiment of the present application includes the first locking members 120 for locking the base 200 of the ceiling light at both ends of the lens plate 110, thereby providing the light source unit 100. And the locking of the base 200 is realized. Due to the locking connection between the light source unit 100 and the base 200, it is not necessary to use bolts to connect the two, and the number of parts required for assembling the ceiling light, the manufacturing cost, and the product assembling requirements are reduced. Further, since the light source unit 100 and the base 200 can be connected directly by hand without using a tool, the alignment can be simplified, the assembling work can be reduced, and the assembling efficiency can be improved. Further, abrasion of the light source unit 100 and the base 200 due to the attachment and detachment of the light source unit 100 and the base 200 a plurality of times can be avoided, the convenience of repair of the light source unit 100 can be improved, and the repair cost of the ceiling light can be reduced.

Here, since the locking portion 121 and the connecting portion 122 form the U-shaped first locking tool 120 with the opening facing downward, the first locking tool 120 has large elasticity and is less likely to be broken. Thus, the life of the first locking device 120 can be extended.

Since the connecting portion 122 uses a U-shaped structure with an opening facing downwards, the ceiling light mounted on the ceiling is detached from the ceiling when the light source unit 100 is damaged and is first locked from the outside of the base 200. It is not necessary to push the locking claw of the tool 120 to separate the first locking tool 120 and the base 200, and the cantilever arm on the side separating the U-shaped lens plate 110 is pushed inward to lock the locking portion 121 and the base 200. Since the and can be separated, the convenience of repairing the ceiling light can be further improved.

As shown in FIG. 1, FIG. 3 and FIG. 7, as a specific embodiment of the lens plate 110 according to the present application, the top end of the connection part 122 is formed to be at the same height as or higher than the top end of the lens plate 110.

When the first locking member 120 and the lens plate 110 are detachably connected, when the first locking member 120 is torn, it can be replaced conveniently.

As a specific embodiment of the lens plate 110 according to the present application, the locking portion 121 and the connecting portion 122 are integrally molded.

By integrally forming the locking portion 121 and the connecting portion 122, it is possible to improve the stability of the entire structure of the first locking tool 120 and achieve a long life.

As shown in FIGS. 1 to 6 and 9, as a specific embodiment of the lens plate 110 according to the present application, a second locking member 130 for locking the light source substrate 140 to the lens plate 110 is further installed. To be done.

When used, the light source board 140 is provided with a second through hole 150 penetrating the light source board 140 and passing the second locking member 130. When assembling the light source unit 100, the lens plate 110 is installed so as to cover the light source substrate 140, and the second locking member 130 of the lens plate 110 and the first through hole 210 of the light source substrate 140 are aligned one to one. In addition, the lens plate 110 is pressed toward the light source substrate 140 until the second locking member 130 passes through the second through hole 150 and is locked with the light source substrate 140, or the light source substrate 140 is moved toward the lens plate 110. Press to.

Specifically, as the second locking member 130, a cantilever arm hook type, ring type or U type locking device or the like may be used as long as the above-mentioned function can be realized.

As a specific embodiment of the lens plate 110 according to the present application, the second locking member 130 and the lens plate 110 are detachably connected. Accordingly, when the second locking member 130 is torn, it can be conveniently replaced.

Specifically, the second locking member 130 and the lens plate 110 may be connected by insertion so that the second locking member 130 and the lens plate 110 can be quickly attached and detached.

As a specific embodiment of the lens plate 110 according to the present application, the second locking tool 130 is a U-shaped locking tool. As a result, the stability of the locking connection between the lens plate 110 and the light source substrate 140 can be guaranteed, and since the second locking member 130 itself has relatively large elasticity, tearing is unlikely to occur during use, and the lens plate 110 Also, it is possible to guarantee a long life of the light source unit 100 and a low repair rate.

As shown in FIG. 2, as a specific embodiment of the lens plate 110 according to the present application, the line connecting the two first locking members 120 and the longitudinal center line of the lens plate 110 form an acute angle. It is provided.

It should be noted that the line connecting the two first locking members 120 here refers to the connecting line between the center lines of the two first locking members 120.

According to the above proposal, when the lens plate 110 (or the light source unit 100) is locked to the base 200 via the first locking member 120, the lens plate 110 (or the light source unit 100) is provided at both ends in the longitudinal direction. Not only this, but also because it is stably connected to the base 200 on both sides in the width direction, the number of the first locking members 120 required for assembling the lens plate 110 (or the light source unit 100) and the base 200 is reduced, and the comparison is made. It is possible to guarantee the stability of the entire structure of the lens plate 110, the light source unit 100, and the ceiling light with a relatively small amount of material.

When the two first locking members 120 are arranged deviated from the same straight line, an angle having a small receiving force of the light source unit 100 is bent by an external force when the light source unit 100 is locked to the base 200. In order to avoid such a situation, the included angle between the line connecting the two first locking members 120 and the center line in the longitudinal direction of the lens plate 110 should be smaller than the included angle between the diagonal line of the lens plate 110 and the center line in the longitudinal direction. It may be provided.

A light source unit 100 according to an embodiment of the present application will be described with reference to FIGS. 1 to 4. The light source unit 100 has a light source substrate 140 and a lens plate 110 detachably connected to the light source substrate 140.

Compared with the prior art, the light source unit 100 according to the embodiment of the present application uses the lens plate 110, so that the light source unit 100 and the base 200 are locked. This reduces the number of parts required for assembling the ceiling light, the manufacturing cost, and the assembling requirements of the product because the connection between the both does not need to use bolts. Further, since the light source unit 100 and the base 200 can be connected directly by hand without using a tool, the alignment can be simplified, the assembling work can be reduced, and the assembling efficiency can be improved. Further, abrasion of the light source unit 100 and the base 200 due to the attachment and detachment of the light source unit 100 and the base 200 a plurality of times can be avoided, the convenience of repair of the light source unit 100 can be improved, and the repair cost of the ceiling light can be reduced.

The first locking member 120 of the light source unit 100 passes through the first through hole 210 and is locked to the outer wall of the base 200.

In the ceiling light according to the embodiment of the present application, the light source unit 100 and the base 200 are locked by using the light source unit 100 described above. This reduces the number of parts required for assembling the ceiling light, the manufacturing cost, and the assembling requirements of the product because the connection between the both does not need to use bolts. Further, since the light source unit 100 and the base 200 can be connected directly by hand without using a tool, the alignment can be simplified, the assembling work can be reduced, and the assembling efficiency can be improved. Further, abrasion of the light source unit 100 and the base 200 due to the attachment and detachment of the light source unit 100 and the base 200 a plurality of times can be avoided, the convenience of repair of the light source unit 100 can be improved, and the repair cost of the ceiling light can be reduced.

As shown in FIGS. 5 and 9, as a specific embodiment of the ceiling light according to the present application, the base 200 is provided with a position restricting tool that restricts the position of the light source unit 100 in the width direction with respect to the base 200. ..

By installing the first locking member 120, the relative position of the light source unit 100 and the base 200 in the longitudinal direction of the light source unit 100 is restricted, and by installing the position restricting tool, the light source unit 100 and the base 200 are separated from each other.

As shown in FIG. 5 and FIG. 9, as a specific embodiment of the ceiling light according to the present application, the position restricting tool has two position restricting pieces 300 facing each other in the base 200 and spaced apart. Then, a mounting region for mounting the light source unit 100 is formed between the two position regulating pieces 300.

Therefore, the mounting efficiency of the ceiling light can be improved.

Specifically, the position regulating piece 300 is provided vertically to the base 200 and is integrally formed with the base 200. Therefore, a stable connection between the two can be ensured, and the processing or assembling work of the ceiling light can be reduced and the assembling efficiency of the ceiling light can be improved as compared with the detachable connection of both.

A restricting tool is provided, and two position restricting tools are arranged so as to restrict the relative positions of both ends of the light source unit 100 and the base 200.

Since the light source unit 100 is long, by restricting one light source unit 100 with two position restricting tools, the center line in the longitudinal direction of the light source unit 100 and the line connecting the centers of the two first through holes 210 are on the same straight line. Since the light source unit 100 and the base 200 are parallel or parallel, the relative position between the light source unit 100 and the base 200 can be guaranteed.
