Technical Field

[0001] The utility model belongs to the technical field of lighting fixtures, and in particular relates to a ceiling lamp with adjustable angle. Background Art

[0002] Ceiling lights are a common lighting device, widely used in shopping malls, supermarkets, hotels and other places. They are small in size and low in energy consumption, which is in line with the trend of energy conservation, emission reduction and low-carbon life.

[0003] The ceiling light is mainly composed of a face ring, a reflective cup assembly, a light source assembly and a radiator. The face ring is used for the installation of the ceiling light and the ceiling of the building. The reflective cup assembly mainly reflects the light source to avoid glare, and the heat dissipation mainly dissipates the heat of the light source assembly to avoid damage caused by overheating.

[0004] Most of the existing ceiling lamps have the function of adjustable illumination angle. However, in some special environments, when the illumination angle of the ceiling lamp changes, the posture angle of the radiator also changes accordingly. Sometimes, the heat dissipation performance of the radiator is insufficient due to the change from a vertical posture to a tilted posture. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a ceiling lamp with adjustable angle to address the deficiencies in the above-mentioned prior art, which can adjust the performance of the radiator and avoid, to a certain extent, insufficient heat dissipation performance caused by changes in the posture angle of the radiator.

[0007] In the above-mentioned angle-adjustable ceiling lamp, when the light source assembly rotates from a vertical position to one side around the pin shaft, the gap between the heat dissipation main frame and the heat dissipation movable frame becomes larger.

[0008] In the above-mentioned angle-adjustable ceiling lamp, the heat dissipation movable frame is an arc plate structure. When the light source assembly is in a vertical position, the inner curved surface of the heat dissipation movable frame abuts against the outer half curved surface of the heat dissipation main frame, and the outer curved surface of the heat dissipation movable frame and the other half curved surface of the outer side of the heat dissipation main frame are on the curved surface of the same virtual cylinder.

[0010] The above-mentioned angle-adjustable ceiling lamp has a heat dissipation main frame with a mounting groove for the adjustment connecting rod to be embedded. The lower end of the adjustment connecting rod is hinged near the lower end of the mounting groove, and the upper end of the adjustment connecting rod is rotatable in the mounting groove. The upper end of the adjustment connecting rod is hinged to the inner side of the heat dissipation movable frame.

[0011] In the above-mentioned angle-adjustable ceiling lamp, the heat dissipation movable frame is embedded with a hinge, and the inner side of the hinge is hinged to the adjustment connecting rod.

[0012] Compared with existing technologies, this utility model has the following advantages: the design of this utility model allows the user to adjust the angle of the light source component, thereby changing the direction of the light. By adjusting the gap between the radiator, the heat dissipation requirements at different angles can be met, ensuring that the lamp maintains good heat dissipation performance under different operating conditions.

[0023] like Figure 1 — Figure 4 As shown, an angle-adjustable ceiling lamp includes a face ring 1, a reflective cup assembly 2, a light source assembly 3 and a radiator 4. The light source assembly 3 is installed at the front end of the radiator 4, and the reflective cup assembly 2 is sleeved and installed at the front end of the light source assembly 3. The light source assembly 3 and the reflective cup assembly 2 are hinged by two pins 5. The face ring 1 is sleeved and installed on the outside of the reflective cup assembly 2. The radiator 4 includes a heat dissipation main frame 4-1 and a heat dissipation mobile frame 4-2. The gap between the heat dissipation main frame 4-1 and the heat dissipation mobile frame 4-2 is adjustable.

[0024] In this embodiment, when the light source assembly 3 rotates from a vertical position to one side around the pin shaft 5, the gap between the heat dissipation main frame 4-1 and the heat dissipation movable frame 4-2 becomes larger.

[0025] It should be noted that, in practice, the lower end of the heat dissipation movable frame 4 - 2 abuts against the reflective cup assembly 2 , so that the light source assembly 3 can only rotate to one side.

[0026] When the light source assembly 3 rotates, the gap between the heat dissipation main frame 4 - 1 and the heat dissipation movable frame 4 - 2 becomes larger, so as to facilitate air circulation and improve heat dissipation efficiency.

[0027] In this embodiment, the heat dissipation movable frame 4-2 is an arc plate structure. When the light source assembly 3 is in a vertical position, the inner curved surface of the heat dissipation movable frame 4-2 and the outer half curved surface of the heat dissipation main frame 4-1 are in contact with each other, and the outer curved surface of the heat dissipation movable frame 4-2 and the outer half curved surface of the heat dissipation main frame 4-1 are on the curved surface of the same virtual cylinder.

[0028] The arc plate structure design of the heat dissipation movable frame 4-2 enables the heat dissipation movable frame 4-2 to closely cooperate with the heat dissipation main frame 4-1 when the light source assembly 3 is vertical, forming an effective heat dissipation surface.

[0029] In this embodiment, the heat dissipation main frame 4-1 is fixed at the rear end of the light source assembly 3, the lower end of the heat dissipation movable frame 4-2 is hinged on the two pins 5, and the upper end of the heat dissipation movable frame 4-2 is connected to the heat dissipation main frame 4-1 through two symmetrical adjustment links 6, and the two ends of the adjustment links 6 are respectively hinged to the heat dissipation movable frame 4-2 and the heat dissipation main frame 4-1.

[0030] The main heat sink frame 4-1 is fixed to the rear end of the light source assembly 3. The mobile heat sink frame 4-2 is connected to the main heat sink frame 4-1 via a pin 5 and an adjustment link 6. This structural design allows the mobile heat sink frame 4-2 to adjust its relative position to the main heat sink frame 4-1 as the light source assembly 3 rotates, thereby maintaining or increasing the heat dissipation effect. The design of the adjustment link 6 provides a mechanism that allows the relative position of the mobile heat sink frame 4-2 and the main heat sink frame 4-1 to be automatically adjusted to adjust the heat dissipation effect.

[0031] In this embodiment, the heat dissipation main frame 4-1 is provided with a mounting groove 7 for the adjustment link 6 to be embedded, the lower end of the adjustment link 6 is hinged in the mounting groove 7 near the lower end, the upper end of the adjustment link 6 is rotatable in the mounting groove 7, and the upper end of the adjustment link 6 is hinged to the inner side of the heat dissipation movable frame 4-2.

[0032] The design of the mounting groove 7 and the adjusting link 6 on the heat dissipation main frame 4 - 1 allows the adjusting link 6 to rotate freely in the mounting groove 7 , thereby adjusting the position of the heat dissipation movable frame 4 - 2 .

[0033] In this embodiment, the heat dissipation movable frame 4 - 2 is embedded with a hinge 8 , and the inner side of the hinge 8 is hinged to the adjustment link 6 .

[0034] The design of the hinge 8 on the heat dissipation mobile frame 4-2 allows the adjustment link 6 to be hinged to the hinge 8, so that the entire heat dissipation mobile frame 4-2 does not need to be replaced when the hinge 8 is damaged, which facilitates later maintenance and replacement.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
