Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to an angle-adjustable embedded lamp. Background Art

[0002] Lamps are essential lighting tools in existing decoration, and downlights are also one of the most common lighting fixtures in decoration.

[0003] After searching, it was found that one adjustment method of existing downlights is to design the lamp housing as an upper and lower lamp housing that are rotatably connected together, with the lamp body placed in the upper lamp housing and the reflector fixed in the lower lamp housing. The lighting angle can be adjusted by rotating the upper lamp housing, and the lower lamp housing remains stationary, thereby maintaining the aesthetics of the downlight fixed on the ceiling. However, since the upper and lower lamp housings of this type of downlight are tightly connected by a set of symmetrical axes, their stability is not very good and they are prone to loosening, resulting in automatic light offset.

[0004] In this regard, the utility model provides a recessed lamp with adjustable angle. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-3 The present invention provides a technical solution for an angle-adjustable embedded lamp. The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] Example 1:

[0020] An angle-adjustable embedded lamp comprises an upper shell 1 and a middle shell 2. The middle shell 2 is arranged at the lower part of the upper shell 1 and the two are fixedly connected. A lamp body 3 is provided at the bottom of the upper shell 1, and a honeycomb mesh 4 is provided at the lower part of the lamp body 3. Honeycomb holes are distributed on the honeycomb mesh 4. The honeycomb holes have a good light scattering effect, so that the light range emitted by the downlight has a smooth and soft transition from the inside to the outside in terms of light intensity, and the light range display effect is good, while also having a good anti-glare effect. A lampshade 5 is provided at the lower part of the honeycomb mesh 4, and a reflective cup 6 is provided at the lower part of the middle shell 2. The reflective cup 6 and the middle shell 2 are connected by a central axis 7. Side connecting members 8 are provided on both sides of the upper part of the reflective cup 6, and fixing slots 9 are provided on both sides of the middle shell 2. A connecting hole is opened on the upper part of the side connecting member 8 and a limiting screw 10 is provided in the inner cavity of the connecting hole. The outer end of the limiting screw 10 is threadedly connected to a nut member matching it, and a light-transmitting plate 11 is provided at the lower mouth of the reflective cup 6.

[0021] Specifically, such as Figure 1 and Figure 3 As shown, the fixing notch 9 is in an arc shape and is a continuous corrugated mouth. The arc shape of the fixing notch 9 matches the trajectory of the upper connecting hole of the side connecting member 8 when it rotates around the central axis 7.

[0022] When used specifically, Figure 1 、 Figure 2 and Figure 3 As shown, to adjust the projection angle of the cover lamp, only the angle of the upper and middle housings need to be adjusted. This can be done after the wiring is connected and before the lamp is installed in the lamp mounting hole. Before rotating the upper and middle housings, the nut must be unscrewed and the limit screw 10 removed. Then, the upper and middle housings can be rotated about the central axis 7. As the upper and middle housings rotate, the side connector 8 will rotate relative to each other. After adjusting the angle, the limit screw is inserted through the connecting hole and into the corresponding position of the fixed notch 9. The nut is then tightened. At this time, the reflector cup 6 remains in a vertical downward position. The side connector 8 can be stopped at any position within the corresponding range of the fixed notch 9. The limit screw 10 and the nut cooperate to limit the position, making it stable and not easy to loosen.

[0023] Example 2:

[0024] The reflector cup 6 is a matte black reflector cup, so that the reflected light will be softer during lighting.

[0025] Further, such as Figure 1 and Figure 2As shown, fixed blocks are symmetrically provided on both sides of the reflective cup 6, and a buckle plate 12 is connected between the fixed blocks on the same side through an axis. The buckle plate 12 is located outside the axis and is provided with a torsion spring. The two ends of the torsion spring are respectively connected to the buckle plate 12 and the fixed block. When installing the lamp, the two sets of buckle plates 12 are flipped upward to drive the torsion spring to twist, and then the upper part of the lamp is placed into the pre-opened lamp installation port until the buckle plate 12 also enters the installation port and is loosened. Then the torsion spring will drive the buckle plate 12 to reset, and push the entire lamp upward to complete the installation of the lamp; the outer periphery of the upper shell 1 is fixedly connected to the metal heat dissipation fins, and the inner side of the metal heat dissipation fins extends to the inner wall of the upper shell 1, so that the heat generated by the internal lamp during lighting can be conducted to the outside through the metal heat dissipation fins for heat dissipation.

[0026] The above is the working process of the entire device. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. Therefore, the scope of the present invention will only be determined by the attached claims.
