Description

Technical Field

[0001] The utility model relates to the technical field of LED light sources, in particular to an LED surface light source. Background Art

[0002] Surface light source refers to the mode of light emission. Compared with LED point light source and ordinary lamp light source, existing surface light sources such as flat panel light source and LED surface light source have the characteristics of soft light, no harm to eyes, power saving and natural light, and are an important direction for the development of light source products in the future.

[0003] The currently used surface light source includes a housing, a light source installed in the housing, and a light-transmitting plate connected to the housing. The following problems exist during use:

[0004] The light-transmitting plate is connected to the shell by a buckle. When a problem occurs and needs to be repaired, it is necessary to apply downward force to remove the light-transmitting plate from the shell, which is inconvenient to disassemble. Moreover, after repeated use, the buckle fails, resulting in the light-transmitting plate being unable to be connected to the shell. Even if the light source can continue to be used, it can only be scrapped and replaced as a whole, which cannot meet the usage needs. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide an LED surface light source with stable connection, convenient operation and long service life.

[0008] In this way, by providing a convex edge at the upper end of the light-transmitting plate, the two sides of the shell are rotatably connected with a clamping plate through a reset structure, when the convex edge abuts against the shell, the buckle is snapped into the bayonet, so that the clamping plate supports the convex edge and the installation of the light-transmitting plate is completed. When it is necessary to disassemble, the clamping plate is rotated in the opposite direction, the buckle is disengaged from the bayonet, and the light-transmitting plate can be removed.

[0009] Among them, the reset structure includes a rotating shaft, two supports are fixedly installed on the shell, the rotating shaft is rotatably connected to the supports, a shaft sleeve is fixedly installed on the rotating shaft, the shaft sleeve is fixedly connected to the clamping plate, torsion springs are sleeved on both sides of the rotating shaft, one end of the torsion spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to the support.

[0010] Wherein, the shell is circumferentially fixed with two retaining edges, and when the clamping plate is clamped with the clamping port, the outer sides of the retaining edges are opposite to the outer sides of the clamping plate.

[0011] Wherein, a support ring is fixed to the retaining edge, and the rotating shaft is rotatably matched with the support ring.

[0012] Wherein, a plurality of heat dissipation fins are fixed between the rib and the shell.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0024] like Figure 1-7 As shown, an LED surface light source includes a shell 1 and a light-transmitting plate 2, wherein the shell is fixedly mounted with a light source opposite to the light-transmitting plate, the light-transmitting plate is protruded upwardly with a convex edge 3, the upper end of the convex edge abuts against the shell, and clamping plates 4 are rotatably mounted on both sides of the shell through a reset structure, the lower end of the clamping plate is protruded inwardly with a buckle 5, and the convex edge is concave to form a bayonet 6 that can be engaged with the buckle.

[0025] In this way, by providing a convex edge at the upper end of the light-transmitting plate, the two sides of the shell are rotatably connected with a clamping plate through a reset structure, when the convex edge abuts against the shell, the buckle is snapped into the bayonet, so that the clamping plate supports the convex edge and the installation of the light-transmitting plate is completed. When it is necessary to disassemble, the clamping plate is rotated in the opposite direction, the buckle is disengaged from the bayonet, and the light-transmitting plate can be removed.

[0026] During implementation, the reset structure includes a rotating shaft 5, two supports 6 are fixedly installed on the shell, the rotating shaft is rotatably connected to the supports, a shaft sleeve 7 is fixedly installed on the rotating shaft, the shaft sleeve is fixedly connected to the clamping plate, torsion springs 8 are sleeved on both sides of the rotating shaft, one end of the torsion spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to the supports.

[0027] In this way, the buckle can be engaged with the bayonet by the provision of the torsion spring.

[0028] During implementation, the housing is circumferentially fixed with two ribs 9, and when the cardboard is engaged with the bayonet, the outer side of the ribs is directly opposite to the outer side of the cardboard, which is convenient for improving the integrity. The height of the ribs is higher than the cardboard, which is convenient for the cardboard to rotate.

[0029] During implementation, the rib is fixed with a support ring 10, and the shaft is rotatably matched with the support ring, so that the shaft installation is more stable.

[0030] During implementation, a plurality of heat dissipation fins 11 are fixed between the rib and the housing to facilitate heat dissipation.

[0031] In practice, the lower end of the buckle has an upwardly inclined inclined surface 14. When the convex edge is close to the housing, the inclined surface allows the convex edge to better push the buckle to rotate outward, and when the buckle is facing the bayonet, the buckle rotates into the bayonet under the action of the torsion spring.

[0032] During implementation, a plurality of internal threaded barrels 12 are fixed on the shell, and the shell is provided with mounting holes 13 opposite to the threaded holes of the internal threaded barrels, so that the shell can be mounted on the ceiling by expansion screws, and the installation of the shell is facilitated by the arrangement of the internal threaded barrels.

[0033] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
