Description

Technical Field

[0001] This utility model relates to the field of lighting devices, and in particular to a lamp body and panel lamp with a new structure that allows for flexible length expansion. Background Technology

[0002] There are several standard sizes for panel light fixtures on the market, such as 300mm*300mm (width*length), 300mm*600mm (width*length), and 300mm*1200mm (width*length); or, while keeping the width constant, several lengths are made according to the actual installation needs of the project, thus forming several sizes of panel light fixtures. For the production of these sizes of panel light fixtures, the current practice mainly involves assembling them using quadrilateral profile frames of different specifications, along with corresponding chassis and related accessories. This structural design and assembly method for panel light fixtures has several problems to some extent, such as high product cost, too many types of materials, and a complex assembly process. For example, patent number 202321401061.X, an LED panel light iron frame, uses a frame formed by combining four profiles to serve as the frame for the panel light fixture; another example is patent number 202322201247.7, a direct-emission panel light system, in which the aluminum frame is also a rectangular frame formed by four profiles, used to fix the back plate and light guide plate.

[0013] Example 1:

[0014] Combination Figure 1As shown, a novel lighting fixture body includes a chassis 1 and side panels 2. The chassis 1 is a sheet metal structure made from a thin metal sheet through a stamping and bending process. The chassis 1 has an overall elongated groove shape, with a groove bottom in the middle and groove sides on both sides. The height of the groove sides is greater than the height of the groove bottom. Both ends of the chassis along its length are open grooves, the width of which is defined by the two groove sides. The cross-section of the chassis is U-shaped. The side panels 2 are plastic structures made through injection molding. The contour shape of one side of the side panel 2 matches the contour shape of the groove end of the chassis 1. In other embodiments, the side panels 2 can also be sheet metal structures made by stamping a thin metal sheet. There are two side panels, arranged symmetrically. When the two side panels 2 are connected to the chassis 1 from the groove ends of the chassis, a continuous, closed groove area is formed on all four sides. This groove area is used to place other components of the lighting fixture. After the side body 2 is connected to the chassis 1, a hard metal sheet and screws (not shown in the figure) are used to fix the side body 2 and the chassis 1 at the connection point to form the lamp body.

[0015] Example 2:

[0016] Combination Figure 2 and Figure 3As shown, a novel lighting fixture body includes a chassis 1 and side bodies 2. The chassis 1 is a sheet metal structure made from a thin metal sheet through a stamping and bending process. The chassis 1 has an overall elongated groove shape, with a groove bottom in the middle and groove sides on both sides. The height of the groove sides is greater than the height of the groove bottom. Both ends of the chassis along its length are open grooves, the width of which is defined by the two groove sides. The cross-section of the chassis is U-shaped. Simultaneously, a receiving portion 11 is provided at the groove bottom of the chassis 1. The receiving portion 11 is a straight groove with a height approximately 1-2 mm lower than the groove bottom of the chassis, and both ends of the receiving portion extend to the two ends of the groove opening of the chassis. The receiving portion 11 can be used to hold the light-emitting strips in the lighting fixture. The side body 2 is a plastic structure made through injection molding. The contour shape of one side of the side body 2 matches the contour shape of the groove end of the chassis 1. In other embodiments, the side body 2 can also be a sheet metal structure made by stamping a thin metal sheet. There are two side bodies 2 arranged symmetrically. When the two side bodies 2 are connected to the base 1 from both ends of the slot side of the base, a continuous and closed groove area is formed, which is used to place other components of the lamp. To make the connection between the base 1 and the side body 2 more accurate and stable, a step 21 is provided on one side of the side body 2. The step 21 is an L-shaped step that runs through one side of the side body, and its structural height is about 1-2 mm lower than the bottom of the inner side of the side body. The side end of the base 1 can be placed on this step 21. Meanwhile, to limit the upward displacement of the chassis 1, several spaced-apart retaining parts 22 are provided on the side body 1 to serve as a limiting function. Each retaining part 22 is a thin-walled lug with one end fixed to the side body and the other end extending outwards. The outward portion of the retaining part 22 is located above the step 21. The retaining part 22 abuts against the upper surface of the side end of the chassis 1 to prevent the chassis 1 from moving upwards, thereby better securing the connection between the chassis 1 and the side body 2. When the two side bodies 2 are connected to the chassis 1 from two different locations, a continuous, enclosed groove area is formed on all four sides. This groove area is used to place other components of the lamp. After the side body 2 is joined to the chassis 1, a rigid metal sheet and screws (not shown in the figure) are used at the connection point to fix the side body 2 to the chassis 1, forming the lamp body.

[0017] A panel light employing the aforementioned novel lamp body structure further includes a light guide plate, a light-emitting strip, and a power supply, in addition to the lamp body itself. The light guide plate can be installed on the top of the lamp body using screws to cover the recessed area in the middle of the lamp body. Alternatively, the light guide plate can be installed on the lamp body using a clamping method or other auxiliary fixing components. The light-emitting strip is fixedly placed at any position at the bottom of the groove in the base 1 or in the receiving portion 11 at the bottom of the groove, with the light-emitting direction of the strip facing the light guide plate. The power supply is located inside the lamp body and is electrically connected to the light-emitting strip.

[0018] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
