Abstract
Description
Technical Field
[0001] This invention relates to the field of lighting technology, and in particular to a lamp. Background Technology
[0002] Ceiling lights, with their simple design and easy installation, are a top choice for many homes and offices. A typical ceiling light consists of a base, frame, and shade, with the light source and driver housed within a cavity formed between these components. As living standards improve and living environments become larger, the required size of ceiling lights also increases. However, large shades are costly and heavy, limiting the overall size of ceiling lights. Furthermore, gaps inevitably exist between the rigid shade and the frame, resulting in poor insect protection. Insects can enter the light fixture through these gaps, affecting both its lighting efficiency and aesthetics. Summary of the Invention
[0003] The purpose of this invention is to at least solve one of the above-mentioned problems. The provided lamp uses a light-transmitting film to replace the traditional diffuser plate or transparent plate cover, making the assembly of the lamp more convenient, the structure simpler, and the cost significantly reduced.
[0004] To achieve the above-mentioned functions, the present invention provides a lighting fixture, including a chassis, a main light source assembly disposed on the chassis, and a side frame extending upward around the chassis. The end of the side frame away from the chassis is a light outlet. The light outlet is provided with a light-transmitting film, and the chassis, side frame, and light-transmitting film surround and form a light mixing cavity.
[0005] Furthermore, a thin film mounting portion is provided on the side frame surrounding the light outlet, and the lamp also includes an elastic mounting member. The thin film mounting portion and the elastic mounting member are interference-fitted, and the edge of the light-transmitting film is sandwiched between the thin film mounting portion and the elastic mounting member.
[0006] Furthermore, the thin film mounting portion includes a first groove disposed inside the side frame, the opening direction of the first groove being at an angle to the opening direction of the light outlet, and the elastic mounting member being embedded in the first groove.
[0007] Furthermore, the film mounting portion also includes a second groove disposed on the inner side of the side frame, the distance from the second groove to the chassis is less than the distance from the first groove to the chassis, and the elastic mounting member is embedded in the second groove.
[0008] Furthermore, the opening direction of the second groove is the same as the opening direction of the light outlet.
[0009] Furthermore, the elastic mounting element is a silicone ring.
[0010] Furthermore, the luminaire also includes an auxiliary light source assembly, which is disposed on the inner surface of the side frame within the light mixing cavity.
[0011] Furthermore, the main light source component and / or the auxiliary light source component include RGBW four-color LED beads.
[0012] Furthermore, the lamp is a ceiling lamp and also includes a bracket. The bracket is fixed to the mounting surface and has a mounting groove. The base has a hanging part on the side opposite to the light outlet. The hanging part and the mounting groove are engaged to install the lamp.
[0013] Furthermore, the light-transmitting film is a nano-bilayer film, which includes a diffusion film and a transparent film stacked together, with the transparent film disposed on the outside of the diffusion film.
[0014] The luminaire provided in this application uses a light-transmitting film instead of a traditional diffuser plate or transparent plate. The advantages of the light-transmitting film are: The cost of the light-transmitting film is at least 50% lower than that of traditional diffuser plates and transparent plates. The double-layer film is packaged in rolls, which reduces transportation costs and warehouse storage space, thus reducing costs as well. When using the light-transmitting film, it can be laid flat and cut with scissors, unlike traditional diffusion plates or transparent plates which require laser or CNC equipment for cutting. Double-layer membranes are thin membrane materials with low density, resulting in a much smaller volume and weight, which significantly reduces the overall weight of the lamp compared to traditional sheet materials.
[0015] Overall, using translucent films for complete lamp assembly is more convenient, the structure is simpler, and the weight and cost of the lamps can be significantly reduced. This is especially true for large-volume lamps, where the application effect is even more pronounced. Attached Figure Description

Detailed Implementation
[0017] The lamps proposed in this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0018] A preferred embodiment of this application shows a ceiling light, the exploded view and cross-sectional view of which are shown below. Figure 1 , Figure 2 As shown. The embodiment of the lamp includes a bracket 7, a base 6, a main light source assembly 5, and a side frame 3. The bracket 7 can be directly fixedly installed on a mounting base such as a roof or wall, and the lamp is installed after the base 6 and the bracket 7 are connected.
[0019] The side frame 3 surrounds the outer periphery of the chassis 6 and extends away from the mounting base. The side frame 3 and the chassis 6 form an accommodating space in which the main light source assembly 5 and the driving assembly (not shown) are disposed. The end of the side frame 3 away from the chassis 6 is the light outlet 8. In this embodiment, the chassis 6 and the side frame 3 are separate structures. In other preferred embodiments, they can also be integrated structures, and this application does not limit this.
[0020] The main light source assembly 5 includes a light source board and LED beads mounted on it. A mounting hole 660 for the light source board is provided on the chassis 6, and the light source board is fixed to the chassis 6 with screws. A driver power supply mounting bracket 650 is also provided on the chassis 6 for mounting the driver assembly. The driver assembly is electrically connected to the main light source assembly 5 and supplies power to the main light source assembly 5. In this embodiment, the LED beads are true-color LED beads (using a combination of R, B, L, and W LED beads), and their mixed light color temperature range can reach from 1800K to 12000K, far exceeding the color temperature range of traditional lighting products. This allows them to easily adapt to different usage scenarios and user needs, and, in conjunction with a lens, makes the light emission more uniform. Whether it's the soft light of the morning or the warm atmosphere of the night, it can provide lighting effects for multiple scenarios. The lamp in this embodiment also includes an auxiliary light source assembly 4, which is a side light source fixed to the inner wall of the side frame 3 with double-sided adhesive to create a side light and shadow effect. The auxiliary light source assembly 4 also uses RGBW four-color true-color LED beads.
[0021] In existing designs, a PC diffuser is typically used to seal the light outlet 8 of the side frame 3, thus blocking the internal light source and forming a mixing cavity. However, large-area diffusers present challenges such as difficult processing, high cost, and heavy weight. In this embodiment, a light-transmitting film 2 replaces the diffuser to seal the light outlet 8. The base 6, side frame 3, and light-transmitting film 2 form the outline of the lamp body, creating a mixing cavity inside. The four-color LEDs in the main light source assembly 5 fully mix their light within this cavity, resulting in a more natural and uniform light color. In this embodiment, the light-transmitting film 2 is a nano-double-layer film, comprising a diffuser film 220 and a transparent film 210 stacked together, with the transparent film 210 positioned on the outer side of the diffuser film 220. The double-layer diffuser film is made of optical-grade PVC material. The diffuser layer 220 ensures soft light emission and high transmittance, while the transparent layer 210 makes the product appear brighter, giving it a crystal-clear feel, and the light color is more transparent after the lamp is turned on.
[0022] Traditional rigid face masks typically use clips to attach to the lamp frame. This embodiment employs a novel mounting structure for installing the light-transmitting film 2. The mounting structure includes a film mounting section and an elastic mounting member 1. The film mounting section is a groove located on the side frame 3 near the light outlet 8, surrounding the light outlet 8. During installation, the light-transmitting film 2 is first placed over the light outlet 8. Then, the elastic mounting member 1 is inserted into the groove, with an interference fit between the groove and the elastic mounting member 1. The light-transmitting film 2 is pressed and fixed within the groove by the elastic mounting member 1. The excess portion of the light-transmitting film 2 not pressed into the groove is trimmed to complete the installation. The elastic mounting member 1 can be made of rubber, plastic, etc.; in this embodiment, it is a silicone ring. After installation, the edge of the light-transmitting film 2 is sandwiched between the silicone ring and the groove. The silicone ring serves both to fix the light-transmitting film 2 and to provide a seal. Compared to the clip structure of rigid face masks, this structure offers better sealing and effectively prevents insects from entering. The groove can be located on the inner or outer side of the side frame 3. In this embodiment, the film mounting portion includes two grooves, such as... Figure 3The first groove 320 and the second groove 310 are shown. The first groove 320 is located inside the side frame 3, and its opening is perpendicular to the light outlet 8. The elastic mounting member 1 is inserted from the side, making the connection more reliable. In other preferred embodiments, the opening direction of the first groove 320 does not necessarily have to be perpendicular to the light outlet 8, as long as there is an angle between them. The second groove 310 is also located inside the side frame 3, but its position is closer to the chassis 6, that is, the distance between the second groove 310 and the chassis 6 is less than the distance between the first groove 320 and the chassis 6. The opening direction of the second groove 310 is the same as the opening direction of the light outlet 8. In this way, during installation, the light-transmitting film 2 directly covers the groove of the second groove 310, making the overall surface of the lamp more flat after installation. Both the first groove 320 and the second groove 310 are provided with elastic mounting members 1, and the two-layer structure makes the connection more reliable.
[0023] The light-transmitting film 2 is a thin film material with low density, resulting in a significantly smaller volume and weight compared to traditional diffuser plates, greatly reducing the overall weight of the lamp. In this embodiment, the lamp is fixed to the ceiling via a bracket 7. The bracket 7 has the following structure... Figure 4 As shown, the bracket 7 is integrally stamped from metal. The bracket 7 has mounting holes 703, through which screws secure it to the ceiling. The bracket 7 also has mounting grooves 701 and eyelet holes 702. Correspondingly, the base 6 has a hanging part 610 and a wire hook 630 on the side opposite to the light outlet 8. Figure 5 As shown, the mounting part 5 is a rivet mounted on the rivet fixing seat 620. The wire hook 630 also has a wire hook fixing seat 640. During installation, first fix the bracket 7 to the ceiling. Then, hook the wire hook 630 on the base 6 onto the hanging eye hole 702 of the bracket 7, allowing the light fixture to be suspended from the bracket 7. Next, align the rivet on the base 6, which serves as the mounting part 610, with the opening end of the mounting groove 701 on the bracket 7. Raise the light fixture so that the rivet inserts into the mounting groove 701. Finally, rotate the light fixture, and the rivet will fall into the connecting end of the mounting groove 701, allowing the light fixture to be hung on the bracket 7, completing the installation. The use of a light-transmitting film makes the light fixture lighter, making mounting and installation easier.
