[0041] The technical solutions of the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] In the following detailed description, reference is made to the accompanying drawings, which form a part of this specification, in which specific embodiments of the present invention are illustrated by way of example. Regarding the drawings, directional terms such as “top,” “bottom,” “inner,” “outer,” “upper,” “lower,” “front,” and “rear” are used with reference to the orientation of the drawings described. Since the components of the embodiments of the present invention can be positioned in many different orientations, the directional terms are for illustrative purposes only and are not intended to be limiting. It should be understood that other embodiments can be used, and structural or logical changes can be made without departing from the scope of the present invention. Therefore, the following detailed description should not be construed as limiting, and the present invention is defined by the appended claims.

[0043] refer to Figures 1 to 3 This utility model proposes a lighting device 100. For example, the lighting device 100 can be in the form of a lamp, such as a light bulb, etc. Of course, the specific form of the lighting device 100 is not limited to this, for example, it can also be in other forms such as a flashlight.

[0044] The lighting device 100 generally includes a housing 1, a light-transmitting cover 2, a light-emitting unit 3, and a switching unit 4. The lighting device 100 is schematically shown in the figure in the form of a light bulb. In this case, the lighting device 100 may also include a lamp holder connected to the end of the housing 1, a heat sink disposed inside the housing 1, etc.

[0045] The housing 1 may include a circumferential sidewall 11 surrounding the internal space S of the housing and has an open housing opening 12. A light-transmitting cover 2 is connected to the housing 1 and covers the housing opening 12. The light-emitting unit 3 is disposed in the internal space S of the housing. For example, the light-emitting unit 3 may include a light source driving board and a light source, such as an LED, mounted on the light source driving board.

[0046] Combination Figure 2 and Figure 3 As best shown, the switching unit 4 may include a slide switch 41 and an operation knob 42, which are directly connected together.

[0047] The slide switch 41 is electrically connected to the light-emitting unit 3, for example, mounted on a light source driver board, and the slide switch 41 includes a moving contact 411 for switching between different positions. In the art, the slide switch 41 may also be referred to as a toggle switch, which typically has multiple positions, and the moving contact 411 can move along a linear direction to switch between the different positions.

[0048] The operating knob 42 may include a knob body 421 and a connecting portion 422 extending from one side of the knob body 421 (i.e., the side facing the interior of the housing 1).

[0049] The knob body 421 can be disposed on the housing 1, for example, disposed on the outer surface of the circumferential sidewall 11 of the housing 1, or partially embedded in the circumferential sidewall 11 or partially embedded in the interior of the housing 1.

[0050] The connecting part 422 can be disposed in the internal space S of the housing and directly connected to the slide switch 41, so that the rotation of the knob body 421 can drive the moving contact 411 to move to realize the position switching of the slide switch 41. It should be noted that since the connecting part 422 is fixed to the knob body 421 or integrated with the knob body 421, the connecting part 422 will make an arc-shaped movement when the knob body 421 is rotated. However, considering the short stroke of this arc-shaped movement and the cooperation between the connecting part 422 and the moving contact 411, the arc-shaped movement of the connecting part 422 can drive the moving contact 411 to move in a straight line without causing the moving contact 411 to disengage from the two connecting arms 4221 of the connecting part 422 during its movement stroke.

[0051] Specifically, the switching unit 4 can be configured to switch the color temperature, beam angle, or power of the lighting device 100. In other words, the switching unit 4 of this invention can be used to adjust one of the various characteristics of the lighting device 100.

[0052] In one embodiment, the connecting portion 422 may include two connecting arms 4221 spaced apart from each other, and at least a portion of the moving contact 411 is positioned between the two connecting arms 4221. Specifically, the two connecting arms 4221 may extend parallel to each other. Of course, the present invention is not limited to this; for example, the two connecting arms 4221 may be spaced apart from each other and extend in a trumpet or bracket shape, which can also achieve cooperation with the moving contact 411.

[0053] In one embodiment, the extending direction of the moving contact 411 intersects the extending directions of the two connecting arms 4221. Specifically, it is perpendicular to the extending directions of the two connecting arms 4221. Of course, the present invention is not limited to this; the extending direction of the moving contact 411 may be inclined relative to the extending directions of the two connecting arms 4221, or even parallel to the extending directions of the two connecting arms 4221.

[0054] In another embodiment, such as Figure 4 As shown, the moving contact 411 may include two contact arms 4111 spaced apart from each other, and a portion of the connecting portion 422 is positioned between the two contact arms 4111. In particular, the connecting portion 422 is in the form of a single connecting arm, preferably, such connecting arm is a zigzag extension.

[0055] In one embodiment, there is a gap between the moving contact 411 and the two connecting arms 4221. Of course, the present invention is not limited to this, and there may be no gap between the moving contact 411 and the two connecting arms 4221.

[0056] In one embodiment, the housing 1 may further include a receiving groove 13 recessed inward from the circumferential sidewall 11. The receiving groove 13 may include a groove bottom wall 131 and a groove sidewall 132 connecting the groove bottom wall 131 and the circumferential sidewall 11. A portion of the knob body 421 is positioned in the receiving groove 13. Of course, the present invention is not limited to this. For example, as mentioned above, the knob body 421 may be disposed on the outer surface of the circumferential sidewall 11.

[0057] Specifically, the lighting device 100 also includes a seal, such as a gasket, a sealing ring, etc., that can be disposed between the knob body 421 and the bottom wall 131 of the recess 13.

[0058] In one embodiment, the slide switch 41 can be disposed on the light-emitting unit 3, for example, at the bottom or side of the light-emitting unit 3, depending on the specific form of the light-emitting unit 3 and the utilization of the internal space S of the housing. Of course, the present invention is not limited thereto; for example, the slide switch 41 can also be disposed on a separate mounting plate other than the light-emitting unit 3.

[0059] In one embodiment, the operating knob 42 may further include a handle portion 423 disposed on the other side of the knob body 421 opposite to the side where the connecting portion 422 is located (i.e., the side facing the outside of the housing 1).

[0060] In one embodiment, the lighting device 100 may include a circuit board disposed within the internal space S of the housing. The light-emitting unit 3 and the sliding switch 41 may be located on the upper and lower sides of the circuit board, respectively. For example, one of the light-emitting unit 3 and the sliding switch 41 may be located on the upper surface of the circuit board, while the other may be located on the lower surface of the circuit board.

[0061] Furthermore, this utility model also proposes a lighting device, comprising: a housing 1, including a circumferential sidewall 11 surrounding an internal space S of the housing and having an open housing opening 12; a light-transmitting cover 2, connected to the housing 1 and covering the housing opening 12; a light-emitting unit 3, disposed on a circuit board located in the internal space S of the housing; and a switching unit 4. The switching unit 4 includes: a slide switch 41, disposed on the circuit board and electrically connected to the light-emitting unit 3 and including a moving contact 411 for switching the position of the slide switch 41; and an operating knob 42, including a knob body 421 and a connecting portion 422 extending from one side of the knob body 421. The knob body 421 is disposed on the housing 1, and the connecting portion 422 is disposed in the internal space S of the housing and directly connected to the slide switch 41, such that rotation of the knob body 421 can drive the moving contact 411 to move to achieve switching of the position of the slide switch 41.
