[0002] LED light strips are formed by assembling several LED lamp beads on a strip-shaped FPC or PCB, and are named because of their strip-shaped shape. LED light strips are energy-saving and environmentally friendly, highly reliable, and have a long life. After installation, they are thin and do not take up space. They can be cut and extended at will according to the length required for installation, and are easy to splice into decorative patterns or texts. Therefore, they are increasingly widely used in the fields of lighting and decoration.

[0003] At present, the installation and fixation of soft light strips in lamps are mainly done by sticking double-sided tape inside the iron frame, with one side sticking to the iron frame and the other side sticking to the soft light strip. During installation, it is not convenient to stick double-sided tape due to the large size of the lamp and the long frame. After the double-sided tape is pasted, the film on the double-sided tape needs to be torn off, and then the co-extruded light strip is pasted, and finally glue is applied on both sides of the soft light strip to prevent it from falling off. This operation is inefficient and costly. Utility Model Content

[0020] The light strip installation fixture, light source module and lamp proposed in the present invention are further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] A light source module in a preferred embodiment of the present application is as follows Figure 1 , Figure 2 As shown, the light source module 5 uses the light strip 2 as the light source, and the light strip 2 is installed in the bracket 3 through the light strip installation clamp 1. In this embodiment, the light source module 5 is used as follows Figure 4 The lamp shown is a ceiling lamp, the bracket 3 is annular and arranged around the main lighting 6. The main lighting 6 is a surface light source that emits light downward, and the light source module 5 emits light laterally to form an ambient lighting around the main lighting 6.

[0022] The bracket 2 is formed by stretching a U-shaped cross section. In this embodiment, the bracket 3 is annular. In other preferred embodiments, it can also be a strip, polygon or various irregular shapes according to the design requirements of the lamp, and this application does not limit this. However, no matter what shape the bracket 3 is, its cross section is U-shaped. Figure 2 The figure shows a bottom plate 301 and side walls 302 arranged on opposite sides of the bottom plate 301. In previous solutions, the light strip 2 is usually adhered to the bottom plate 301 by double-sided tape. It is necessary to first stick the double-sided tape on the bottom plate 301, then tear off the film on the double-sided tape, stick the light strip 2, and finally apply glue on both sides of the light strip 2 to prevent it from falling off. This operation is inefficient and costly. In order to fix the light strip 2 in the bracket 3, the present application provides a light strip installation clamp 1. During installation, the light strip 2 and the light strip installation clamp 1 are first connected, and then the light strip 2 is fixed in the bracket 3 by the light strip installation clamp 1.

[0023] The structure of the light strip mounting fixture 1 in the preferred embodiment is as follows Figure 2 , Figure 3As shown, it includes a bottom surface 103, and two groove walls 102 are arranged in parallel on the two opposite sides of the bottom surface 102, and the bottom surface 103 and the two groove walls 102 form a light strip accommodating groove 104. The width of the light strip accommodating groove 104 matches the light strip 2. In order to fix the light strip 2, an inwardly protruding buckle structure 105 is arranged on the inner side of the groove wall 102. The minimum dimension between the two buckle structures 105 is smaller than the width of the light strip 2, so that the light strip 2 cannot fall out after being inserted into the light strip accommodating groove 104. In order to fix the light strip installation fixture 1 in the bracket 3, an elastic arm 101 is arranged on the outer side of each of the two groove walls 102, and one end of the elastic arm 101 and the groove wall 102 is fixedly connected to the connection end 1013, and the other end is a free end 1014. The elastic arm 101 extends from the connection end 1013 to the outside and the top of the accommodating groove 104, the distance between the free end 1014 and the bottom surface 103 is greater than the distance between the upper end of the groove wall 102 and the bottom surface 103, and the distance between the free ends 1014 of the two elastic arms 101 is greater than the distance between the connection ends 1013 of the two elastic arms 101. At the same time, before being inserted into the bracket 3, the distance between the free ends 1014 of the two elastic arms 101 is greater than the width between the two side walls 302 of the bracket 3. When the light strip installation fixture 1 is installed into the bracket 3, the light strip installation fixture 1 is pushed in from the opening of the U-shaped cross section of the bracket 3 until the bottom surface 103 is pushed to the position of the bottom plate 301, and the elastic arm 101 is elastically deformed inward, and its free end 1014 abuts against the side wall of the bracket 3 to fix the light strip installation fixture 1. In order to prevent the light strip installation fixture 1 entering the bracket 3 from falling out, a bending portion 303 bent inwardly is provided at the upper end of the side wall 302 of the bracket 3 .

[0024] The elastic arm 101 can be set at any position outside the groove wall 102. In this embodiment, the connection end 1013 of the elastic arm 101 and the groove wall 102 is set near the groove wall 102 and outside the end of the groove wall away from the bottom surface 103. In other embodiments, it can also be set at a lower position, which is not limited by the present application. The elastic arm 101 includes a first extension section 1012 and a second extension section 1011. The first extension section 1012 extends from the connection end 1013 in a direction away from the groove wall 102. The second extension section 1011 connects one end of the first extension section 1012 away from the groove wall 102 and extends upward in a direction away from the bottom surface 103.

[0025] The light strip installation fixture 1 is a plastic part, which has good elasticity as a whole. When installed, the light strip is maintained by the elastic deformation of the plastic and fixed to the side wall 302 of the bracket 3. At the same time, since the plastic part has a certain thickness relative to the metal part, the thickness of the free end 1014 of the elastic arm 101 in this embodiment is 1 mm, and the thickness of the free end 1014 in other preferred embodiments is also greater than or equal to 1 mm. In order to meet the light distribution requirements, the light source module 5 also includes a translucent panel 4. Since the free end 1014 has a thickness, it can be used as a supporting component of the translucent panel 4. The translucent panel 4 is sandwiched by the bending portion 303 and the free end 1014 of the bracket 3 when installed. In addition, in some preferred embodiments, the plastic part can also be made of transparent material, which avoids the light strip installation fixture 1 from affecting the light output of the light strip 2. In other preferred embodiments, the translucent panel 4 can also be a lens, a diffuser plate, a micro-prism plate, etc., which is not limited in this application.

[0026] Conventional installation clips are usually of fixed specifications. The light strip installation clip 1 proposed in the present application is extruded from a plastic material. It is a strip-shaped whole before installation. When in use, it is cut to the required length along the length direction according to actual needs. Such a structure is convenient for storage and transportation. At the same time, since the light source we use is a light strip 2, and the outer layer of the co-extruded light strip is wrapped with soft PVC silicone, during transportation, the PVC will be deformed and twisted for a certain length (such as 100mm). In this case, a single small clip cannot shape the twisted part, which can easily cause the light strip 2 to be uneven after installation. The light strip installation clip 1 proposed in the present application can be cut to any length. In the above case, the light strip installation clip 1 can be cut to a length of 110mm. It is stuck to the twisted position during assembly and completely covers the twisted position, thereby correcting the co-extruded light strip to the correct position, making the installation effect better.

[0027] The above description of the preferred embodiments of the present invention is for illustration and description, and is not intended to be exhaustive or limited to the specific forms disclosed. Obviously, many modifications and changes may be made, which may be obvious to those skilled in the art and should be included in the scope of the present invention defined by the appended claims.
