Description

Technical Field

[0001] The utility model relates to lighting products, in particular to an accessory used for lighting lamps, especially a reflective cup. Background Art

[0002] Existing reflective cups usually include a trumpet-shaped cup body and a cup base fixedly connected to the bottom of the cup body, and the cup base is provided with a plug hole. However, existing reflective cups are usually made of metal or plastic in one piece, and the surface of the metal or plastic material itself is full of micropores, which results in the inability to silver-plate the surface of the reflective cup made of these materials. This will cause micropores to appear on the surface of the silver-plated layer and affect the reflection effect. Therefore, only vacuum-plated reflective film can be used to cover these micropores through the coating layer. However, after the reflective film is plated in the reflective cup, the reflective film is easily blackened due to the close distance between the light source and the reflective film and the high temperature, thereby affecting the service life.

[0019] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] Embodiment 1

[0021] Combination Figure 1 and Figure 2A reflective cup shown in the figure comprises a trumpet-shaped glass cup body 1, wherein the glass cup body 1 has a reflective cavity, a metal lamp holder 2 is embedded in one end of the glass cup body 1, and a silver-plated mirror layer 3 is provided on the inner wall surface of the reflective cavity; in this embodiment, by adopting a glass cup body 1 made of glass, the surface micropores of the inner wall of the reflective cavity are fewer than those of metal or plastic, and the surface is smoother, so that after the silver-plated mirror layer 3 is provided in the reflective cavity, the reflective effect of the silver-plated mirror layer 3 is better, and the reflective surface reflection efficiency of the silver-plated mirror layer 3 is about 80% higher than that of traditional vacuum coating, and the glass cup body 1 and the silver-plated mirror layer 3 are more heat-resistant, the melting point of silver is 960 degrees, while that of traditional vacuum coating is only 150 degrees, thereby preventing the reflective surface from blackening or coking and affecting the service life.

[0022] It is worth noting that the metal lamp holder 2 of the present embodiment is made of aluminum alloy, so that the reflective cup can dissipate heat through the metal lamp holder 2 .

[0023] like Figure 2 As shown, in this embodiment, a glass tube 11 is integrally provided at one end of the glass cup body 1 close to the metal lamp holder 2. The glass tube 11 is inserted into the metal lamp holder 2. An adhesive layer is provided between the metal lamp holder 2 and the glass tube 11. The glass tube 11 and the metal lamp holder 2 are tightly fixed together by the adhesive layer to prevent the glass cup body 1 from detaching from the metal lamp holder 2.

[0024] It is worth noting that the edge of the other end of the glass cup body 1 of this embodiment is provided with a clamping edge 10 protruding outwards, and the reflective cup can be fixedly mounted on the lamp through the clamping edge 10.

[0027] In this embodiment, a clamping head 9 is provided at the upper end of the clamping slot 7, and a supporting ring surface 8 is provided at the lower end. The top-view width of the supporting ring surface 8 is larger than the top-view width of the clamping head 9, and the connecting ring 5 is supported on the supporting ring surface 8. The position of the connecting ring 5 is limited by the supporting ring surface 8, so that the connecting ring 5 is embedded and installed in the clamping slot 7, which is convenient for installation.

[0028] In this embodiment, the inner wall of the clamp 9 is in contact with the outer wall of the arc segment 4, and a sealant layer is provided at the connection between the arc segment 4 and the clamp 9; the sealant layer can seal the arc segment 4 and the clamp 9, and at the same time make the connection between the two more stable.

[0029] The connection between the arc segment 4 and the connecting ring 5 of this embodiment is provided with an outwardly extending latching protrusion 6, which is latched in the latching groove 7, forming a hook angle between the arc segment 4 and the latching protrusion 6, and the clamping head 9 is latched on the hook angle; under the action of the latching protrusion 6, the connection between the glass cup body 1 and the metal lamp holder 2 can be made more stable to prevent falling off, and the clamping head 9 is latched on the hook angle to further prevent shaking or loosening between the glass cup body 1 and the metal lamp holder 2.

[0030] It is worth noting that the glass cup body 1, arc segment 4, connecting ring 5 and latching protrusion 6 of the present embodiment are all an integrated structure made of glass material, and the whole can be formed in one step, so the production and assembly are convenient.
