Description

Technical Field

[0001] The utility model relates to the technical field of lighting appliances, and particularly relates to a flexible wall washer lamp. Background Art

[0002] Wall washer lamps are commonly used lighting appliances, which are connected and installed to the wall. Due to different indoor and outdoor designs, the wall may have a curved or cornered wall structure. Therefore, the wall washer lamp installed on the wall should also be able to bend corresponding to the wall to meet the installation requirements of the lamp. The substrate of the traditional wall washer lamp is integrally set as a cuboid, and then the whole substrate is installed inside the wall washer lamp. When in use, the traditional substrate will be broken after being bent for a long time, resulting in inconvenient installation of the traditional wall washer lamp.

[0003] In the existing solution, there is a flexible wall washer lamp disclosed in Chinese Patent Application Publication No. CN111102501A on May 5, 2020, which includes: a bendable connecting plate; a plurality of brackets, the brackets are installed on the connecting plate, and the plurality of brackets are spaced apart; a flexible light strip, the flexible light strip is installed on the brackets, and the connecting plate is located on one side of the flexible light strip; a bendable light shielding plate, the light shielding plate is installed on the brackets and located on the other side of the flexible light strip. The flexible light strip can be bent according to the requirements of the installation environment, and by arranging a plurality of the brackets at intervals, after the flexible light strip is bent, the connecting plate and the light shielding plate can better fit on both sides of the flexible light strip. Its structure is simple, the bending function of the wall washer lamp is realized, so that it can fit the curved surface of the arc-shaped building, without the need for multiple wall washer lamp groups to be connected in series, reducing the connectors, lowering the cost, and it can better fit the curved surface of the arc-shaped building, improving the lighting effect.

[0004] In the disclosed solution, during long-term use, the outer surface of the flexible light strip is likely to age due to heat, thus affecting its connection effect with the brackets. Summary of the Utility Model

[0005] Aiming at the deficiencies existing in the prior art, the purpose of the present utility model is as follows:

[0006] First, to provide a flexible wall washer lamp with a heat dissipation device, and delay the aging of the outer surface of the flexible light strip by enhancing the heat dissipation effect.

[0007] To achieve the above object, the present utility model provides the following technical solutions: It includes a flexible outer shell, a transparent sealant, a plurality of light-emitting elements, a control board, and a cable connection port. The transparent sealant seals the plurality of light-emitting elements in the flexible outer shell. The control board is electrically connected to the light-emitting elements. The cable connection port is electrically connected to the control board. The control board is arranged in the flexible outer shell. A first heat dissipation device is arranged on the side surface of the flexible outer shell. A first cavity for the coolant to pass through is arranged in the first heat dissipation device. One end of the first heat dissipation device is provided with a first inlet, and the other end of the first heat dissipation device is provided with a first outlet. Both the first inlet and the first outlet are communicated with the first cavity.

[0008] As the solution with the first heat dissipation device, its working principle is to conduct the heat generated when the light-emitting elements work into the coolant in the first cavity. The heat dissipation solution in its actual use can be to inject a coolant with a high specific heat capacity into the first cavity and continuously absorb heat when the light-emitting elements work to ensure that the flexible outer shell is at an appropriate temperature. However, when this heat dissipation solution is implemented, the continuous temperature rise of the coolant will still slightly affect the temperature of the flexible outer shell. It can also be in the form of continuously injecting low-temperature coolant and discharging high-temperature coolant from the first inlet and the first outlet to continuously absorb heat and ensure that the flexible outer shell is at an appropriate temperature.

[0009] Optionally, a second heat dissipation device is further arranged in the flexible outer shell. A second cavity for the coolant to pass through is arranged in the second heat dissipation device. The second cavity is communicated with the first cavity.

[0010] Optionally, the first cavity is communicated with the second cavity through the first outlet. A liquid discharge port is arranged on the second cavity.

[0011] Optionally, the upper surface of the second heat dissipation device is attached to the lower surface of the light-emitting elements, and the lower surface of the second heat dissipation device is attached to the upper surface of the control board.

[0012] As the solution with the additional second heat dissipation device, its main function is to cut off the heat conduction between the light-emitting elements and the control board to ensure that the control board will not overheat and affect its service life when working.

[0013] Optionally, plugs are arranged at both ends of the flexible outer shell.

[0014] The beneficial technical effect of the present utility model is that the coolant in the first cavity absorbs the heat generated when the light-emitting elements work, so as to ensure that the flexible outer shell will not age due to overheating during operation. Description of the Drawings

[0020] Embodiment 1

[0021] Referring to Figure 1-2 As shown, a flexible wall washer includes a flexible housing 1, a transparent sealant 2, a plurality of light-emitting elements 3, a control board 4 and a cable connection port 5. The transparent sealant 2 seals the plurality of light-emitting elements 3 inside the flexible housing 1. The control board 4 is electrically connected to the light-emitting elements 3. The cable connection port 5 is electrically connected to the control board 4. The control board is disposed inside the flexible housing 1. A first heat dissipation device is provided on the side surface of the flexible housing 1. A first cavity 6 for the coolant to pass through is provided inside the first heat dissipation device. A first inlet 7 is provided at one end of the first heat dissipation device, and a first outlet 8 is provided at the other end of the first heat dissipation device. Both the first inlet 7 and the first outlet 8 are communicated with the first cavity 6. Specifically, the first cavity 6 is arranged in a "U" shape to ensure that the first inlet 7 and the first outlet 8 are on the same side. Plugs 9 are provided at both ends of the flexible housing 1. The above-mentioned flexible housing 1, transparent sealant, and control board 4 can all deform freely within a certain range without affecting their original functions.

[0022] As a solution with the first heat dissipation device, its working principle lies in conducting the heat generated when the light-emitting component 3 works to the coolant in the first cavity 6. The heat dissipation solution in its actual use can be to inject a coolant with a high specific heat capacity into the first cavity 6, and continuously absorb heat when the light-emitting component 3 works to ensure that the flexible housing 1 is at an appropriate temperature. However, when this heat dissipation solution is implemented, the continuous temperature rise of the coolant will still slightly affect the temperature of the flexible housing 1. It can also be in the form of continuously injecting low-temperature coolant and discharging high-temperature coolant from the first inlet 7 and the first outlet 8 to continuously absorb heat and ensure that the flexible housing 1 is at an appropriate temperature.

[0023] Embodiment 2

[0024] As Figure 3 shown, the difference from Embodiment 1 is that a second heat dissipation device is further provided in the flexible housing 1. A second cavity 10 for the coolant to pass through is provided in the second heat dissipation device, and the second cavity 10 is communicated with the first cavity 6. The first cavity 6 is communicated with the second cavity 10 through the first outlet 8, and a liquid discharge port is provided on the second cavity 10. The upper surface of the second heat dissipation device is attached to the lower surface of the light-emitting component 3, and the lower surface of the second heat dissipation device is attached to the upper surface of the control board 4.

[0025] As a solution with an additional second heat dissipation device, its main function is to cut off the heat conduction between the light-emitting component 3 and the control board 4 to ensure that the control board 4 will not overheat and affect its service life when working.

[0026] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
