Since fresh lights are generally used in supermarkets or large shopping malls, they are usually ordered in bulk when purchasing, and the quantity for one order is relatively large. During transportation, the above-mentioned components are packaged separately, wherein the rear cover 2, the first front cover 6 and the second front cover 4 can be stacked in multiples during packaging, thus saving space and reducing transportation costs. After being delivered to the user, these components are assembled as shown in Figure 1 in the installation relationship, and the finished fresh light lamp cross-sectional view is shown in Figure 3.

The structure of the rear cover 2 is shown in FIG. 4 and FIG. 5, and includes an open end 208. In this embodiment, the first front cover 6 has a semi-circular, semi-closed configuration. In other implementations, it may also have an arc-shaped surface configuration. Its opening faces the rear cover 2, and the first front cover 6 covers the back cover 2 After the open end 208, the rear cover 2 and the first front cover 6 together form an accommodation space 8, and the light source assembly 5 and the power supply assembly 3 are both accommodated in the accommodation space. In this embodiment, the light source assembly 5 includes a light source board and LED lamp beads arranged on it. In other preferred embodiments, it may also be a COB light source or an LED light source module with a lens. In this embodiment, the light source board of the light source assembly 5 and the open end 208 are parallel and of the same size, and are arranged just inside the open end 208 and face the first front cover 6 to emit light. In other embodiments, the light source can also be arranged in a side-emitting manner. As shown in the figure, the power supply assembly 3 includes a PCB board and electronic components arranged on it. One end of the PCB board is arranged in the lamp cap 1 at the tail of the rear cover 2. The first front cover 6 can be an optical element for distributing the emitted light, such as setting a diffusion layer on the surface, mixing phosphors in the material, or directly made of a filter material to achieve a specific light color. In this embodiment In the example, the first front cover is a light-transmitting cover, which is injection-molded from PMMA material. The second front cover 4 has an opening in the middle, and the lateral extension size exceeds that of the first front cover 6 and the rear cover 2. After the rear cover 2 passes through the opening in the middle of the second front cover 4, the second front cover 4 is arranged outside the open end 208 of the rear cover 2. The second front cover 4 can also play a light distribution function for optical elements. In this embodiment The middle and second front cover 4 is a reflector, and its inner side is a reflecting surface. After the light emitted by the light source assembly 5 is emitted through the first mask 6, part of the lateral light is then emitted after being adjusted by the second front cover 4. In addition to serving as a light distribution element, the second front cover 4 can also play a decorative role. In this embodiment, the second front cover 4 is made of engineering plastic ABS, which is injection molded, and various toners can be mixed to form different colors. The rear cover 2 can adopt the same color, which makes the whole lamp more coordinated and beautiful. The first front cover 6 is accommodated in the second front cover 4.

As shown in Figure 3, the assembled fresh light power supply assembly 3 is housed inside the rear cover 2 and needs to be connected to an external power source. Therefore, a lamp cap 1 is provided on the opposite side of the open end 208 of the rear cover 2 for electrical connection to The power source, the lamp holder 1 has a threaded bayonet, and in this embodiment, the lamp holder 1 is a standard E27 lamp holder. In other embodiments, the lamp holder can also be E14, G10, etc.

In order to facilitate the user's assembly, the rear cover 2 and the first front cover 6 and the second front cover 4 are all connected by snap connections, so that the connection and disassembly between them can be quickly realized without the aid of tools. Refer to Figure 4, Figure 5, Figure 6, and Figure 7 for specific structure.

4 is a cross-sectional view of the rear cover 2 in this embodiment. As shown in the figure, the rear cover 2 is assembled with the first front cover 6 through a first buckle portion 201 provided on the inner side wall near the opening end 208 thereof. As shown in FIG. 6, the first front cover 6 is provided with a buckle portion 601 that cooperates with the buckle portion 201. In this embodiment, the buckle portion 601 is an annular groove. During installation, the first front cover 6 is aligned with the open end 208 of the rear cover 2 and pressed into forcefully, and the first buckle part 201 inside the open end and the annular groove of the buckle part 601 are engaged to realize the connection and fixation.

The external structure diagram of the rear cover 2 is shown in FIG. 5, the rear cover 2 is assembled with the second front cover 4 through a second buckle part arranged outside the opening end 208. The rear cover 2 is provided with a bearing surface 203. The second buckle portion includes at least two claws 202. In this embodiment, there are four claws 202. The claws 202 are arranged above the bearing surface 203 and are not connected to the bearing surface. 203 contact, that is, a gap is left between the claw 202 and the bearing surface 203. As shown in FIG. 7, the second front cover 4 is provided with a mounting ring 401, and the mounting ring 401 is provided with a notch 402 allowing the pawl 202 to pass through. The number of notches 402 is the same as the pawl 202, and the two are arranged oppositely. During installation, after aligning the notches 402 on the second front cover 4 with the four claws 202 on the rear cover 2, the claws 202 can pass through the gaps 402 along the axis of the lamp. When the claws 202 pass through the mounting ring, Rotate the second front cover 4 around the axis of the lamp, so that the pawl 202 rotates to the top of the non-notched position of the mounting ring 401. The mounting ring 401 is sandwiched between the pawl 202 and the bearing surface. At this time, the mounting ring 401 and the bearing surface The surface 202 is in contact, and the installation is complete.

In order to prevent excessive relative rotation between the rear cover 2 and the second front cover 4, for example, the claw 202 is turned to the next notch 402, which makes the connection unreliable. In this embodiment, a limit part is also added. The limit part is arranged on the side of the mounting ring 401 facing the claw 202. The limit part includes at least two limit ribs 403, and both sides of each notch 402 are respectively provided with A limit rib 403, when the claw 202 rotates around the axis of the lamp, it will be blocked by the limit rib 403 and cannot continue to rotate.

The above description of the preferred embodiments of this application is for the purpose of illustration and description, and is not intended to exhaust or limit the application to the specific forms disclosed. Obviously, many modifications and changes may be made, and these modifications and changes may be useful to those skilled in the art. It is obvious to the person that it should be included in the scope of this application as defined by the appended claims.
