Description

Technical Field

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

[0002] The light emitted by traditional lighting lamps tends to be natural light, and its light is evenly distributed in each polarization direction. In order to reduce or eliminate reflected light and improve the clarity of the field of view, that is, to adjust the polarization direction of the light so that only light with a specific polarization direction can pass through, while blocking or weakening light in other directions, polarized lamps have been introduced. Polarized lamps are widely used in daily life and the field of photography. Further, in order to improve the adaptability of polarized lamps to various scenarios, the irradiation angle of polarized lamps can be adjusted. For example, in the Chinese utility model patent application with the application number 201420145780.4, the first adjustment connection block cooperates with the second adjustment connection block and the card slots opened therein to realize the adjustable angle of the polarized lamp; another example is the Chinese utility model patent application with the application number 202022161846.7, which enables the first fixing bolt to pass through the rotation hole and cooperate with the second fixing bolt to pass through the arc groove to realize the adjustable angle of the polarized lamp.

[0027] This application provides a polarizing lamp with adjustable angle. The above-mentioned polarizing lamp with adjustable angle includes a reflector cup, an adjusting surface ring and a light-emitting component. The reflector cup is provided with a polarization channel and a wedge surface. The extending direction of the polarization channel intersects with the wedge surface. The wedge surface is located at one end of the reflector cup. The peripheral wall of the reflector cup is connected to the adjusting surface ring. At least one arc-shaped sliding area is provided on the adjusting surface ring. The light-emitting component is slidably connected to the arc-shaped sliding area. The position where the light-emitting component is used to connect to the arc-shaped sliding area is biased towards one side of the light-emitting component. And the light-emitting direction of the light-emitting component is arranged towards the polarization channel. And the light-emitting component is arranged at one end of the reflector cup where the wedge surface is provided. The arc-shaped sliding area extends in a direction away from the wedge surface.

[0028] The above-mentioned angle-adjustable polarized lamp has a wedge-shaped surface at one end of the reflector cup. The extending direction of the polarization channel intersects with the wedge-shaped surface, and the light-emitting direction of the light-emitting component is set towards the polarization channel, so that the polarization direction of the light beam of the light-emitting component is adjusted at the reflector cup, achieving the polarized light effect of the angle-adjustable polarized lamp. In addition, in cooperation with the arc-shaped sliding area extending away from the wedge-shaped surface, the light-emitting component is slidably connected to the arc-shaped sliding area. The position of the light-emitting component for connecting to the arc-shaped sliding area is set towards one side of the light-emitting component, so that the light-emitting component can be offset relative to the polarization channel and can be telescopic relative to the polarization channel, but the light-emitting direction of the light-emitting component is towards the polarization channel. In this way, the interference of the adjustment surface ring on the movement of the light-emitting component is reduced, the adjustment range of the irradiation angle of the angle-adjustable polarized lamp is increased, and the cut-off angle of the angle-adjustable polarized lamp can be adjusted, thereby improving the adaptability of the angle-adjustable polarized lamp.

[0029] It should be noted that the position of the light-emitting component for connecting to the arc-shaped sliding area is set towards one side of the light-emitting component, which can be understood as follows: when the light-emitting component is an axisymmetric structure, the position of the light-emitting component for connecting to the arc-shaped sliding area deviates from the axis of symmetry; when the light-emitting component is a non-axisymmetric structure, the relative two side surfaces of the light-emitting component are respectively set as the first side surface and the second side surface.
