Background

A lighting fixture is a household appliance that people use daily, and is adapted to be mounted on an attachment such as a ceiling for illumination, such as indoor illumination. The illumination lamps can be classified into fixed illumination lamps and adjustable illumination lamps according to adjustability of the irradiation direction of light emitted from the illumination lamps. The illumination angle of the fixed illumination lamp is fixed after the fixed illumination lamp is installed, and the requirement that a user adjusts the illumination angle cannot be met. The illumination lamp with the adjustable illumination angle can realize the adjustment of the illumination angle and multi-angle illumination. When the user adjusts the illumination angle, the user can manually or automatically adjust the illumination angle through preset parameters so as to realize multi-angle illumination.

Fig. 1A of the accompanying drawings shows a conventional lighting lamp with an adjustable lighting angle, in which a press ring Y presses a rotating body Z and is fixed by a screw fixing method. The rotation of the rotating body Z1 of the light fixture shown in fig. 1A requires a large height, resulting in limited application of the light fixture, for example, it cannot be used in a small ceiling interlayer space. In addition, the shape of the rotating body Z of the lighting fixture shown in fig. 1A is larger than 1/2 balls, and the lighting fixture needs to be manufactured by a die-casting process or other processes, so that the process requirement is high, and poor rotation is likely to occur.

Fig. 1B of the accompanying drawings shows another conventional illumination angle adjustable illumination lamp, in which an inner side of a top of a barrel housing T and a top of a heat sink S of a rotating body Z2 are provided with arc-shaped concave cavities, and a rolling ball G is provided between the barrel housing T and the heat sink S, so that the rotating body Z2 can be rotated when a user or an operator applies an external force to the rotating body Z2. The lighting fixture shown in fig. 1B realizes the rotation of the rotating body Z2 relative to the barrel casing T through the rolling ball G, which requires high precision of the rolling ball G, the barrel casing T and the arc-shaped concave cavity of the heat sink S, and the outer surface of the rolling ball G and the inner surface of the arc-shaped concave cavity are smooth, otherwise the rotating body Z2 would be difficult to rotate relative to the barrel casing T. Next, the rotation of the rotating body Z2 of the lighting fixture shown in fig. 1B with respect to the barrel cover T is substantially achieved by the rolling of the rolling ball G, so that the rotation direction of the rotating body Z2 of the lighting fixture shown in fig. 1B is not easily controlled. Finally, the lighting fixture shown in fig. 1B realizes the rotation of the rotating body Z2 relative to the barrel housing T by the rolling ball G. Therefore, when the external force for rotating the rotating body Z2 is removed, the rotating body Z2 may be reset by its own weight, resulting in failure in adjustment of the light irradiation direction.

To facilitate rotation of the light source assembly 20 within the operating chamber 100, the inner surface 2020 is provided with an arcuate shape. Optionally, the inner surface 2020 and the inner side surface 122 of the support 12 are both arc-shaped, and a corresponding radius of the inner surface 2020 is the same as a corresponding radius of the inner side surface 122 of the support 12, so that when the light source assembly 20 is driven to rotate relative to the inner side surface 122 of the support 12, the inner surface 2020 of the light source assembly 20 can be attached to the inner side surface 122 of the support 12. Further, the inner surface 2020 of the light source assembly 20 can be attached to the inner side surface 122 of the support 12 by the retaining member 42, so that when the light source assembly 20 is driven to rotate relative to the inner side surface 122 of the support 12, a friction force is generated between the inner surface 2020 of the light source assembly 20 and the inner side surface 122 of the support 12. In other embodiments, to reduce (or avoid) the friction between the inner surface 2020 of the light source assembly 20 and the inner side surface 122 of the support 12, the inner surface 2020 of the light source assembly 20 is away from the inner side surface 122 of the support 12 when the light source assembly 20 is driven to rotate relative to the inner side surface 122 of the support 12.

As shown in fig. 2 to 9C of the drawings, the illumination device according to the embodiment of the present invention further includes a lubricating mechanism 50, wherein the lubricating mechanism 50 is disposed between the light source assembly 20 and the inner side surface 122 of the support 12 to separate the light source assembly 20 from the inner side surface 122 of the support 12, so as to reduce (or avoid) the friction force generated between the inner surface 2020 of the light source assembly 20 and the inner side surface 122 of the support 12 and to make the light source assembly 20 more easily rotate. Accordingly, the connecting element 40 is configured to keep the rotating cover 30 pressed against the outer side 121 of the supporting member 12 and the light source assembly 20 pressed against the lubricating mechanism 50. At this time, after the external force driving the light source assembly 20 to rotate is removed, the friction force between the rotating cover 30 and the outer side 121 of the supporting member 12 keeps the rotating cover 30 and the light source assembly 20 to be located at the expected adjusting position synchronously, and the utility model discloses the change of the irradiation direction of the light emitted by the lighting fixture.
