[0024] The lamp provided by the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0025] A preferred embodiment of the lamp provided by the present application is a ceiling-mounted lamp, and its exploded structure diagram and sectional view are shown in Figs. 1 and 2. Figure 1 、 Figure 2 The embodiment lamp comprises a hanging bracket 7, a chassis 6, a main light source assembly 5, and a side frame 3. The hanging bracket 7 can be directly fixed and installed on a mounting base such as a roof or a wall, and the chassis 6 and the hanging bracket 7 are connected to realize lamp installation.

[0026] The side frame 3 surrounds the outer circumferential side of the chassis 6 and extends away from the mounting base. The side frame 3 and the chassis 6 form a containing space, and the main light source assembly 5 and a driving assembly (not shown) are arranged in the containing space. An end of the side frame 3 away from the chassis 6 is a light outlet 8. In the embodiment, the chassis 6 and the side frame 3 are in a split structure, and in other preferred embodiments, they can also be in an integrated structure, which is not limited in the present application.

[0027] The main light source assembly 5 comprises a light source plate and LED lamp beads arranged thereon. The chassis 6 is provided with a light source plate fixing hole 660, and the light source plate is fixed on the chassis 6 by screws. The chassis 6 is also provided with a driving power supply fixing seat 650 for installing the driving assembly. The driving assembly is electrically connected with the main light source assembly 5 to supply power to the main light source assembly 5. In the embodiment, the LED lamp beads are true color light beads (R, B, L, and W four kinds of beads are used in proportion), and the color temperature range of the mixed light can reach 12000K from 1800K, far exceeding the color temperature range of traditional lighting products, which can easily adapt to different use scenarios and user needs, cooperate with the lens, and make the light emission more uniform. Whether it is soft light in the morning or warm atmosphere at night, it can provide multi-scene lighting effect. The embodiment lamp further comprises an auxiliary light source assembly 4, and the auxiliary light source assembly 4 is a lateral light source fixed on the inner wall of the side frame 3 by double-sided adhesive tape to create a side light effect. The auxiliary light source assembly 4 also adopts RGBW four-color true color light beads.

[0028] In the prior design, the light outlet 8 of the side frame 3 is usually closed by a diffuser cover made of PC material to shield the internal light source to form a mixing cavity. However, the large-area diffuser cover has problems of processing difficulty, high price, and heavy weight. In the embodiment, the light-transmitting film 2 is used to close the light outlet 8 instead of the diffuser cover, and the bottom plate 6, the side frame 3, and the light-transmitting film 2 surround to form the outline of the lamp body, and a mixing cavity is formed inside. The four-color lamp beads in the main light source assembly 5 are fully mixed inside, and the light color is more natural and uniform. In the embodiment, the light-transmitting film 2 is a nano double-layer film, which includes a diffuser film 220 and a transparent film 210 arranged in layers, and the transparent film 210 is arranged outside the diffuser film 220. The double-layer diffuser film is made of optical-grade PVC material, the diffuser layer 220 can ensure that the lamp emits soft light with high transmittance, and the transparent layer 210 can make the product appearance brighter and give people a crystal-clear feeling, and the light color is more transparent after lighting.

[0029] The traditional hard cover is usually clamped by a buckle and the frame of the lamp. In order to install the light-transmitting film 2, a new installation structure is adopted in the embodiment. The installation structure includes a film installation part and an elastic mounting piece 1. The film installation part is a groove arranged on the side frame 3 near the light outlet 8, and the groove surrounds the light outlet 8. During installation, the light-transmitting film 2 is first covered on the light outlet 8, and then the elastic mounting piece 1 is embedded in the groove. The groove and the elastic mounting piece 1 are in interference fit, the light-transmitting film 2 is fixed in the groove by the elastic mounting piece 1, and after cutting off the excess part of the light-transmitting film 2 that is not pressed into the groove, the installation is completed. The elastic mounting piece 1 can be a rubber piece, a plastic piece, etc. In the embodiment, the elastic mounting piece 1 is a silica gel ring. After installation, the edge of the light-transmitting film 2 is clamped between the silica gel ring and the groove, and the silica gel ring not only fixes the light-transmitting film 2, but also can play a sealing role. Compared with the buckle structure of the hard cover, such structure has better sealing performance, which can effectively prevent mosquitoes from entering. The groove can be arranged on the inner side of the side frame 3, or on the outer side of the side frame 3. In the embodiment, the film installation part includes two grooves, as shown in Figure 3The first groove 320 and the second groove 310 are shown respectively. The first groove 320 is arranged on the inner side of the side frame 3, and the opening of the first groove 320 is perpendicular to the light outlet 8. The elastic mounting member 1 is inserted from the side to make the connection more reliable. In other preferred embodiments, the opening direction of the first groove 320 does not have to be perpendicular to the opening direction of the light outlet 8, as long as there is an angle between the two. The second groove 310 is also arranged on the inner side of the side frame 3, and is closer to the chassis 6, that is, the distance from the second groove 310 to the chassis 6 is smaller than the distance from the first groove 320 to the chassis 6. The opening direction of the second groove 310 is the same as the opening direction of the light outlet 8. When installed, the light-transmitting film 2 directly covers the opening of the second groove 310, so that the surface of the lamp after installation is more flat.

[0030] The light-transmitting film 2 is a thin film material with small density and volume weight. Compared with the traditional diffusion plate, the weight of the lamp is greatly reduced. The lamp in the embodiment is fixed on the ceiling by the hanging bracket 7. Figure 4 As shown in the figure, the hanging bracket 7 is integrally stamped from metal material. The hanging bracket 7 is provided with a mounting hole 703, and a screw is used to fix the hanging bracket 7 on the ceiling through the mounting hole 703. The hanging bracket 7 is also provided with a mounting groove 701 and a lifting ring hole 702. Correspondingly, the chassis 6 is provided with a hanging part 610 and a wire hook 630 on the side away from the light outlet 8. Figure 5 As shown in the figure, the hanging part 5 is a rivet arranged on a rivet fixing seat 620. The wire hook 630 is provided with a wire hook fixing seat 640. During installation, the hanging bracket 7 is first fixed on the ceiling, the wire hook 630 on the chassis 6 is hung on the lifting ring hole 702 of the hanging bracket 7, and the lamp can be hung on the hanging bracket 7. Then, the rivet on the chassis 6 as the hanging part 610 is aligned with the opening end of the mounting groove 701 of the hanging bracket 7, the lamp is lifted, the rivet is inserted into the mounting groove 701, and finally the lamp is rotated, the rivet falls into the connecting end of the mounting groove 701, and the lamp can be hung on the hanging bracket 7, and the installation is completed. After the light-transmitting film is used, the lamp is lighter, and the hanging installation is easier.

[0031] The description of the preferred embodiments of the present application is for the purpose of illustration and description, and is not intended to limit or confine the present application to the specific form disclosed. Obviously, many modifications and changes can be made, which can be obvious to those skilled in the art, and should be included in the scope of the present application defined by the appended claims.
