The lamp housing 20 is located on the rim 12 of the front surface of the housing 10 and covers the lamp cavity. The back of the housing 10 is provided with a circuit board mounting position for mounting and fixing the printed circuit board 30.

The terminals 31 of the assembled printed circuit board 30 lead into the wires 32, and the wires 32 are held fixed in the wire clips 14 and thus oriented and positioned.

The utility model discloses lighting device main part and LED lighting device are particularly useful for domestic appliance, are used as domestic appliance panel or inside LED lighting device. Correspondingly, the embodiment of the utility model provides a still another aspect still provides a domestic appliance, including foretell LED lighting device. The LED lighting device is fixedly mounted on a plate material such as a panel or an inner wall of a home appliance by a fixing member 13 provided on the back surface of the lighting device main body case 10.

With continuing reference to fig. 1 to 3 and further reference to fig. 4, fig. 4 schematically illustrates a structure of a lighting device main body from an end view according to an embodiment of the present invention.

In the embodiment shown in the figures, the wire clamp 14 of the lighting device body is U-shaped, having a first clamp arm 141 and a second clamp arm 142. The first clip arm 141 is fixed to the rear surface of the housing 10, and the second clip arm 142 is bent from one end of the first clip arm 141. An open clamping space is formed between the two clamping arms for the lead 32 to pass through. In use, the wires for mounting the printed circuit board 14 are usually disposed on the back of the housing 10 so that the wires 32 can enter the clamping space from the opening of the wire clip 14 and be clamped and fixed in the clamping space. The U-shaped wire clamp 14 adopting the double-clamping-arm mechanism has the characteristics of simple structure and convenient forming. Such a wire clip 14 can be formed integrally with the housing 10 of the lighting device body, which can reduce the production cost.

However, it should be understood by those skilled in the art that the illustration is merely exemplary and that the wire clamp 14 may have other clamping and securing structures, or other shapes, and may be removably secured to the back of the housing 10.

With continued reference to the drawings, in the embodiment shown, the wire clamp 14 may be positioned on the frame 12 with the clamping space offset from the terminals 31 of the assembled printed circuit board 30. The offset arrangement here means that the wires 32 from the terminals 31 of the circuit board 30 need to be reversed before passing through the clamping space of the wire clamp 14, i.e. the clamping space is not aligned with the terminals 31 of the circuit board 30.

For example, the wire clips 14 may be positioned adjacent to the terminals 31 of the assembled printed circuit board 30 to avoid the lengthy path required before the wires 32 are secured in the clamping spaces, and the clamping spaces of the wire clips 14 may be positioned at an angle or perpendicular relative to the terminals 31 so that the wires 32 are bent or angled accordingly before entering the clamping spaces.

Such a design makes the lighting device main body of the embodiment of the present invention, when inevitably needing to pull the wire 32 in the installation and use process, because of the dislocation arrangement of the clamping space and the terminal 31, the wire clip 14 will share a part of the pulling force, thereby reducing the pulling force applied to the terminal 31 (for example, the welding port in general), avoiding the wire 32 from being broken by the terminal 31, and improving the connection structure strength and reliability of the wire 32 in the lighting device main body.

With continued reference to fig. 4, in the embodiment shown in the figures, the wire clamp 14 further includes a limiting portion 143. The stopper 143 is disposed at an end of the second clip arm 142 near the opening of the clip space, and the stopper 143 is formed by extending the end of the second clip arm 142 toward the first clip arm 141. Thus, the distance between the limiting portion 143 and the first clamping arm 141 is smaller than the thickness of the clamping space (i.e., the distance between the first clamping arm 141 and the second clamping arm 142 in the clamping space).

The design is such that when the wire 32 is fixedly held in the holding space, it is not easily pulled out from the holding space by the restriction of the stopper portion 143. Since the wire 32 generally has a certain elasticity, when the wire 32 is to be placed in the clamping space, a pushing force towards the clamping space needs to be applied to the wire 32, so that the wire 32 is elastically deformed, and is squeezed into the clamping space of the wire clip 14 and constrained by the positioning portion 143, so as to be unable to easily come off, thereby further ensuring that the wire 32 can be stably clamped and fixed in the wire clip 14. And the fixation can further enable the wire clip 14 to share the pulling force of the wire 32 when being pulled, further avoid the terminal 31 from being pulled apart, and improve the reliability of the lighting device main body in use.

With continued reference to fig. 4, in the embodiment shown in the figure, the first clamping arm 141 and the second clamping arm 142 are further provided with a guide portion 144 at the end near the opening of the clamping space. The guide portion 144 functions to provide a guide for placing the wire 32 into the clamping space of the wire clamp 14. Accordingly, the guide portion 144 may be configured in an arc shape (e.g., rounded corners) or an inclined shape (e.g., beveled corners) such that the opening of the clamping space is shaped like a trumpet, with the size of the opening being larger away from the clamping space than the size of the opening being closer to the clamping space. Such a design facilitates easy pushing of the wire 32 from the opening of the clamping space into the clamping space of the wire clamp 14.

In the specific embodiment shown in the figures, the first and second clamp arms 141 and 142 are each provided with a guide 144 at the end near the opening of the clamping space. However, it should be understood by those skilled in the art that in other embodiments, the guide portion 144 may be provided at the end of the first clamping arm 141 or only the end of the second clamping arm 142 near the opening of the clamping space.

Referring to fig. 4, in the embodiment shown in the figure, the length of the first clamping arm 141 is greater than the length of the second clamping arm 142. Since the first clipping arms 141 are fixed on the back of the housing 10, such a design also facilitates the wire 32 to enter the clipping space of the wire clip 14 from above the back of the housing 10 (i.e. the side of the second clipping arms 142) without being blocked by other structures on the main body of the lighting device.

It should be understood by those skilled in the art that the illustration is merely an example, and in other embodiments, the first clamping arm 141 and the second clamping arm 142 may have the same length, or the length of the second clamping arm 142 may be greater than that of the first clamping arm 141. When the length of the second clamping arm 142 is greater than that of the first clamping arm 141, the wires 32 can enter the clamping space of the wire clamp 14 from the space between the second clamping arm 142 and the back of the housing 10, and can be restrained in the space between the second clamping arm 142 and the back of the housing 10, and can also play a role in avoiding wire disorder under appropriate circumstances.

With continued reference to fig. 4, in the embodiment shown in the figure, the first clamping arm 141 and the second clamping arm 142 of the wire clamp 14 are both parallel to the plane of the frame 12 of the housing 10 of the lighting device body, and the first clamping arm 141 and the second clamping arm 142 are vertically arranged on the back of the frame 12. The design is such that the clamping space is also parallel to the plane of the housing rim 12 and therefore the wires 32 clamped therein are also parallel to the plane of the housing rim 12. For LED lighting devices, such a lighting device body structure is more advantageous for a flat design of the overall device, especially for LED lighting devices as panels or interiors of household appliances.

It should be understood by those skilled in the art that the illustration is merely exemplary, and in other embodiments, the wire clamp 14 may have other designs, for example, the direction of the clamping space may be inclined or even perpendicular to the plane of the frame 12 of the housing 10 according to actual needs. Accordingly, in the case of the dual-clip arm U-shaped wire clip 14, the first clip arm 141 and the second clip arm 142 may be oriented obliquely or perpendicularly to the plane of the frame 12.

Referring to fig. 4, in the embodiment shown in the drawings, the distance between the first clamping arm 141 and the second clamping arm 142 is smaller than the diameter of the wire 32, i.e., the thickness of the clamping space of the wire clamp 14 is smaller than the diameter of the wire 32. As described above, the leads 32 that mount the printed circuit board 30 generally have some elastically deformable ability. The wire clamp 14 thus designed can further stabilize the fixation of the wire 32 in its clamping space, improving the ability of the wire 32 to resist pulling, and further avoiding the wire 32 from being pulled apart at the terminal 31 (typically a solder joint).

To sum up, the embodiment of the utility model provides a lighting device main part is through setting up wire clip 14 at the casing 10 back, utilizes wire clip 14 centre gripping to fix the wire 32 of drawing forth from the wiring end 31 of assembling printed circuit board 30, leads and the centre gripping location to wire 32 in the lighting device main part, can avoid the security and the reliability problem that the circuit is chaotic, be torn easily and bring.

The fixture provided on the back of the housing 10 of the lighting device body can fix the lighting device body to a plate material such as a panel or an inner wall of a home appliance, so that such a lighting device body is particularly suitable for use as an LED lighting device for a panel or an interior of a home appliance.
