Description

Clip light

The present invention relates to a lighting device, and more particularly to a clip light that can be placed on the side of a screen.

Traditional lighting devices are mostly fixed and bulky, such as chandeliers, recessed lights, table lamps, and the like. When the user only needs partial illumination or partial enhanced illumination, for example, only need to illuminate the screen (such as the screen of the desk machine, the screen of the notebook computer, etc.), the luminaires disposed adjacent to the screen are generally used. At present, there are currently lamps on the market that can be fixed on the screen. For example, a USB lamp using a small coil has a USB connector at one end of the coil and a light source (such as an LED) at the other end. When used, the USB connector is connected to a USB connector of a host (such as a desk or a notebook). The user can bend the coil to illuminate the light source toward the screen. At this time, the entire luminaire is only supported by the USB connector, so the length of the coil is usually not long, which causes the light source to be pulled too far, so that the range of illumination of the light source is limited. For example, the fixture is clamped and fixed, and the entire structural weight is supported by the clamp. The clamp is located on one end side of the entire fixture, so the clamp needs to provide sufficient clamping force to enable the fixture to be firmly fixed. In addition, the fixture only holds the screen frame on opposite sides, and the clamping area of the fixture is usually large, which may cover the display area of the screen portion, making the lamp unsuitable for a narrow border screen. For example, the luminaire fixed by double-sided tape has the entire structural weight supported by the double-sided adhesive. The weight and the torque of the double-sided adhesive can be limited, so the weight and volume of the luminaire are small, so that the light source can not be pulled too far. The range of illumination of the light source is limited.

In view of the problems in the prior art, the present invention provides a clip lamp that utilizes a counterweight to reduce the torque experienced by the fixed structure of the clip lamp, helps to improve the stability of the clip lamp fixation, and increases the position of the light source relative to the entire clip lamp. Design flexibility.

A clip lamp according to the present invention comprises a light source, a first clip member and a second clip member. The first clamping member has a first clamping portion and a lamp connecting portion connected to the first clamping portion, and the light source is connected to the lamp connecting portion. The second clamping member has a second clamping portion and a weight disposed on the second clamping portion, and the first clamping portion is movably coupled to the second clamping portion. Thereby, when the clip light clip is placed on the side of a structure (such as the side of the desktop screen shell or the side of the notebook screen shell), the weight and the light source can be opposite to the side of the structure. Torque, which helps to reduce the torque that the first clamping portion and the second clamping portion bear when clamping the side of the structure, thereby increasing the stability of the clip lamp when it is fixed to the side of the structure. It helps to increase the design flexibility of the light source relative to the overall position of the clip light.

The advantages and spirit of the present invention will be further understood from the following detailed description of the invention.

Please refer to Figure 1 and Figure 2. According to an embodiment of the invention, the clip lamp 1 comprises a light source 10, a first clip member 12 and a second clip member 14. The first clamping member 12 has a first clamping portion 122 and a lamp connecting portion 124 connected to the first clamping portion 122. The light source 10 is connected to the lamp connecting portion 124. The second clamping member 14 has a second clamping portion 142 and a weight 144 disposed on the second clamping portion 142 (shown in hidden lines in the figure), the first clamping portion 122 and the second clamping portion Portions 142 are movably connected. Thereby, when the clip light 1 is disposed on a screen 2 (such as but not limited to a desk screen), the light source 10 can provide illumination to the screen 20 of the screen 2 (shown in broken lines in FIG. 2); wherein the light source 10 has A socket 102, the light source 10 can obtain external power (for example, from a notebook computer or a desktop computer or other power supply) via an electrical connection cable 11 (shown in broken lines in the figure) plugged into the socket 102. Device or connection interface). When the clip lamp 1 is mounted, the first clamping portion 122 is placed on the outer casing 22 of the screen 2, because the weight 144 and the lamp connecting portion 124 are located at the first clamping portion 122 with respect to the direction of gravity (indicated by an arrow in FIG. 2). The two sides of the joint with the second clamping portion 142, so the weight 144 drives the first clamping portion 122 and the second clamping portion 142 close to each other to clamp the outer casing 22. In this embodiment, the first clamping portion 122 is pivotally connected to the second clamping portion 142, and the pivoting axial direction A1 is indicated by a cross mark in FIG. 2 . Therefore, in the perspective of FIG. 2, the weight 144 (or the second clip 14) generates a clockwise moment with respect to the pivotal axis A1, and the light source 10 (or the light source 10 together with the first clip 12) The counterclockwise moment is generated with respect to the pivotal axis A1 such that the two moments cause the first clamping portion 122 and the second clamping portion 142 to be close to each other and clamped to the outer casing 22. In addition, the foregoing two moments resist each other, which can reduce the torque that the fixing structure of the clip lamp 1 (including the first clamping portion 122 and the second clamping portion 142 in this embodiment) can withstand; this can be analyzed by simple static analysis. Yes, no further details. In other words, when the first clamping member 12 and the second clamping member 14 are clamped on an object (for example, clamped on the upper side of the outer casing 22), the weight 144 and the lamp connecting portion 124 are located at the object (ie, the outer casing 22). The side helps to reduce the torque experienced by the fixed structure of the clip lamp 1, and also helps to enable the center of gravity extension of the clip lamp 1 to pass or approach the upper surface 22a of the outer casing 22, thereby causing the first clip 12 and the second clip The clamping force of the pair of outer casings 22 is in principle sufficient to prevent the movement of the clamp lamp 1 relative to the outer casing 22 (including rotation) (wherein, when the center of gravity extension of the clamp lamp 1 passes through the upper surface 22a of the outer casing 22, the clamp lamp 1 is relatively The outer casing 22 does not rotate). Additionally, the weight of the weight 144 can be determined based on the weight of the light source 10 and the possible relative position of the clip light 1 to the outer casing 22 when in use, such as the weight 144 being equal to the light source 10. Light source 10 can utilize, but is not limited to, light emitting diode illumination.

Please also refer to Figure 3. In addition, in the embodiment, the first clamping portion 122 has a supporting portion 1222 and an abutting portion 1224 protruding from the supporting portion 1222 , and the first clamping portion 122 is supported by the supporting portion 1222 and the second clamping portion 142 . connection. When the clip lamp 1 is disposed on the outer casing 22, the support portion 1222 and the abutting portion 1224 respectively contact the upper surface 22b and the front surface 22c of the outer casing 22; wherein the abutting portion 1224 prevents the second clip member 14 from being affected by the weight 144 The first clip 12 is caused to drag to the right in the perspective of FIG. In practice, the supporting portion 1222 and the abutting portion 1224 respectively have a sliding pad 1222b, 1224b on the surfaces 1222a, 1224a for abutting the upper surface 22a and the front surface 22b of the outer casing 22 to increase the supporting portion 1222 and the abutting portion. The friction of the portion 1224 with the outer casing 22 contributes to the stability of the clip lamp 1 on the outer casing 22. In practice, the anti-slip pads 1222b, 1224b can be, but are not limited to, rubber pads.

In the present embodiment, the lamp connecting portion 124 includes a C-shaped elastic clip 1242, and the light source 10 is clamped to the C-shaped elastic clip 1242.
