Background technique

LED (Light Emitting Diode, light emitting diode) is a solid-state semiconductor device that can convert electrical energy into visible light. LED has the advantages of small size, low energy consumption, long life, pure light color, high brightness, low heat, environmental protection and low carbon, and is internationally recognized as a new type of green light source in the 21st century. Traditional LEDs are mainly used in traffic signal display, automotive industry, building aviation obstruction lights, airport navigation lights and other fields, and now they should be more and more widely used in indoor and outdoor lighting of buildings, urban beautification, and landscape lighting.

Most of the existing LED panel lights have a frame that fixes the illuminant inside to form a panel light structure. However, the existing frame structure is generally only connected by plugging or snapping, and the connection strength is insufficient, resulting in a short service life of the panel light. On the other hand, the joints of the outer frame of the panel light are insufficiently sealed, resulting in light leakage and other phenomena.

Therefore, the inventor considers improving the outer frame structure of the existing LED panel light, and this case arises from it.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

An outer frame structure of an LED panel light, the outer frame includes four frame pieces and four arc-shaped corner pieces, and an arc-shaped corner piece is arranged between two adjacent frame pieces to form a rectangular outer frame body; each The first frame piece is an L-shaped bent body, and its vertical and horizontal directions respectively have a longitudinal card slot and a horizontal card slot. Corresponding ends of the shaped corner pieces are mated and inserted to form an outer frame connection structure.

Further, the transverse card slot is a T-shaped card slot.

Further, the longitudinal slot is an L-shaped slot.

Further, each of the arc-shaped corner pieces is an arc-shaped L-shaped piece, and its two sides that are mated with the frame piece extend outward to form an extension, each extension is L-shaped and is inserted into the corresponding frame piece. The extension part is provided with two lock holes, and each lock hole is adapted to the through hole at the corresponding position of the frame member to form a positioning and locking channel.

Further, the two locking holes are respectively located on the two upper end surfaces of the extension part.

Further, each arc-shaped corner piece extends to both sides to form two lapping wings, and each lapping wing overlaps with the surface of the corresponding frame piece to form an outer frame sealing structure.

Further, each arc-shaped corner piece is provided with an installation hole, thereby forming an installation structure around the outer frame of the LED panel light.

Further, each arc-shaped corner piece is integrally formed.

Compared with the prior art, the utility model has the following advantages:

1. The utility model utilizes the joint locking of the screw and the screw channel to realize the double connection and fixation of the frame piece and the arc-shaped corner piece, effectively increasing the connection strength;

2. Use the overlapping wings extended from the arc-shaped corner piece to cooperate with the frame piece to form a sealing structure at the joint between the frame piece and the arc-shaped corner piece, thereby solving the problem of light leakage at the seam of the panel light.
