Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

In order to more clearly understand the dimming device, a working lamp in the lighting fixture is taken as an example and a main body part is a housing of the working lamp.

As shown in fig. 1 to 6, the working lamp includes a housing 1, a light-emitting body 2, a power switch 3 for controlling the operation of the light-emitting body 2, a battery 4 for supplying power to the light-emitting body, a light-adjusting device capable of adjusting the brightness of the light-emitting body, and a base 5, wherein the housing 1 can rotate relative to the base 5 through a rotating mechanism 6, so that the housing 1 and the light-emitting body 2 mounted on the upper portion of the housing 1 can rotate as required to direct light to a desired direction. The rotation mechanism 6 is prior art and will not be described in detail here. In the embodiment, the main improvement lies in the dimming device, which includes a potentiometer 7 installed in a main body (i.e., a housing) and a rotary disc 8 installed on an operation handle 71 of the potentiometer, where the potentiometer 7 in the figure is located on a circuit board 10 and used for being connected to a power supply loop of the light emitting body 2 (see fig. 7), and the rotary disc 8 is rotated to drive the operation handle of the potentiometer 7 to rotate, so that a movable contact of the potentiometer 7 moves to a proper position, and finally brightness adjustment of the light emitting body is realized. In order to drive the rotating disc 8 conveniently, and want the rotating disc 8 not to be protruded on the housing 1, in this embodiment, a window 11 is opened on the housing 1, the peripheral surface of the rotating disc 8 is partially exposed in the window 11, and the peripheral surface of the rotating disc 8 exposed in the window 11 is not higher than the outer surface of the housing 1, so that not only can the purpose of dimming be conveniently realized, but also the misoperation caused by mistakenly touching the rotating disc 8 can be effectively prevented.

In order to make the entire dimmer compact, it is preferable that the turntable 8 be configured as follows: the device comprises a hollow disc body 81, one end face (namely, the right end face in fig. 3) of the disc body is open for accommodating the potentiometer 7, a hollow column 82 axially extends from the other end face (namely, the left end face in fig. 3) of the disc body 81, the hollow column 82 is sleeved on the operating handle 71, and the peripheral surface of the turntable 8 exposed in the window 11 is the peripheral surface of the disc body 81. Meanwhile, in consideration of the fact that the rotary disk 8 can smoothly drive the operating handle 71 of the capacitor 7 to rotate, the inner wall of the cylinder 82 and the surface of the operating handle are respectively provided with mutually meshed teeth, namely a first tooth 821 on the inner wall of the cylinder and a second tooth 711 on the surface of the operating handle, so as to improve the combination degree of the two. When the potentiometer is installed, the rotary disc 8 is axially moved and then sleeved on the potentiometer 7, so that the first tooth portion 821 in the cylinder 82 is meshed with the second tooth portion 711 on the operating handle 71 of the potentiometer, and then the rotary disc 8 is screwed into the screw hole in the end portion of the operating handle 71 through the bolt 9 to axially limit the rotary disc 8 on the potentiometer 7.

For convenient processing and assembly, the shell 1 is assembled into a whole by screws after being spliced by the left shell 1a and the right shell 1b, the left shell 1a and the right shell 1b are respectively provided with an encapsulating layer 1c matched with the shape of the left shell 1a and the right shell 1b, so that the friction force and the comfort degree during holding are improved, and the window 11 is arranged at the splicing part of the left shell and the right shell. In order to make the rotation of the turntable 8 more stable, a guiding arc surface 12 extending into the tray body extends from the edge of the right housing 1b opposite to one end surface of the tray body 81, please refer to fig. 4 and 5. Meanwhile, considering that the interference of the edge of the window 11 is prevented when a user dials the rotary disc 8, the peripheral side wall of the window 11 is designed into an inclined plane 13, so that the window 11 is gradually enlarged from inside to outside. Furthermore, the side wall around the window 11 is also provided with a bulge 14 which is arranged around the turntable and is close to the turntable 8, and the bulge 14 can improve the strength of the window 11 so as to prolong the service life of the window.

In addition to the above embodiments, the power switch 3 is not required to be disposed in the working lamp, and at this time, the potentiometer is a potentiometer having a power switch capable of controlling the operation of the light emitting body 2, such as a type RP09 potentiometer, so that the potentiometer can be used to adjust the brightness of the light emitting body, and can also have a switching function to provide lighting fixtures of different styles, so as to meet the use requirements of different users.
