Description

Technical Field

[0001] The utility model relates to the technical field of wall washer lamps, in particular to a strong heat dissipation wall washer lamp. Background Art

[0002] LED wall washers, also known as linear LED floodlights, etc., are also called LED linear lights because of their long strip shape. They allow the light to wash across the wall like water. They are mainly used for architectural decorative lighting and to outline the contours of large buildings. LEDs are widely used because of their energy-saving, high luminous efficiency, rich colors, and long life.

[0003] LED wall washers typically have a large number of installed lamp beads. If heat buildup isn't dissipated promptly, it can cause the beads to gradually heat up, impacting their luminous efficacy and lifespan. High temperatures not only reduce the LED's luminous efficiency, leading to light decay, but can also cause internal electronic components to overheat, impacting circuit stability and overall lamp performance. Furthermore, overheating can cause degradation of the lamp's outer casing, increasing the risk of fire and compromising product safety. Existing wall washers primarily dissipate heat through ventilation holes designed to harness natural wind, but this approach is ineffective. Therefore, a new wall washer with enhanced heat dissipation was proposed. Utility Model Content

Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0031] Reference Figures 1 to 3 The embodiment of the present invention provides a strong heat dissipation wall washer lamp, comprising a shell 10, a light-emitting component 20 and a heat dissipation component 30. The shell 10 has a rectangular shape and comprises a shell body 11, an end cover 12 and a transparent lampshade 13. The end cover 12 is arranged at both ends of the shell body 11, and the transparent lampshade 13 is arranged on the upper end surface of the shell body 11. The shell body 11, the end cover 12 and the transparent lampshade 13 together form a closed inner cavity of the shell 10. A mounting plate 40 is arranged in the shell 10, and the light-emitting component 20 is arranged in the inner cavity of the shell 10 and mounted on the upper end surface of the mounting plate 40. The light-emitting component 20 includes a circuit board 21 arranged on the upper end surface of the mounting plate 40 and a plurality of lamp beads 22 arranged on the circuit board 21. When in operation, the light emitted by the lamp beads 22 passes through the transparent lampshade 13 and irradiates the wall. The heat dissipation component 30 includes a cold block 31, a cooling plate 32 and a radiator 33. The cold block 31 is arranged in the inner cavity of the shell 10, and the cooling surface of the cooling fin 32 is embedded in the cold block 31. The cooling fin 32 absorbs the heat of the cold block 31, thereby reducing the temperature of the cold block 31; the heat dissipation surface of the cooling fin 32 is in contact with the radiator 33, and the radiator 33 passes through the bottom wall of the shell 10 and is exposed outside the shell 10. Specifically, a mounting groove 312 is provided on the side of the cold block 31 close to the bottom wall of the shell 10, and the cooling fin 32 is installed in the mounting groove 312. The depth of the mounting groove 312 is equal to the thickness of the cooling fin 32. The radiator 33 includes a substrate and a heat sink, and one side of the substrate is in contact with one side of the cold block 31 and at the same time in contact with the heat dissipation surface of the cooling fin 32. The heat sink is arranged on the side of the substrate away from the cold block 31.

[0032] Furthermore, the mounting plate 40 separates the inner cavity of the housing 10 into a first cavity and a second cavity, and the first cavity and the second cavity are distributed vertically, with the first cavity located above the second cavity. The light-emitting component 20 is disposed in the first cavity, and the heat dissipation component 30 is disposed in the second cavity. First through holes 41 are provided at both ends of the mounting plate 40 to connect the first cavity and the second cavity. The cold block 31 is disposed in the second cavity and separates the second cavity into a third cavity and a fourth cavity. A second through hole 311 is provided on the cold block 31 to connect the third cavity and the fourth cavity.

[0033] The second cavity is provided with a mounting groove 312. The mounting groove 312 forms an internal circulation airflow around the first and second cavities through the mounting groove 312, allowing hot air in the sealed inner cavity of the housing 10 to flow through the second through-hole 311, thereby contacting the cold block 31 and achieving heat exchange between the hot air and the cold block 31.

[0034] The cold block 31 and the mounting groove 312 are both slidably connected to the housing 10. Specifically, a protrusion 37 is provided on the side wall of the housing 10, and the cross-section of the protrusion 37 is T-shaped. The sides of the cold block 31 and the first fan 34 are both provided with grooves 38 corresponding to the protrusion 37. The cold block 31 and the first fan 34 slide on the protrusion 37 through the groove 38, thereby achieving a slidable connection between the cold block 31 and the mounting groove 312 and the housing 10. The cold block 31 and the first fan 34 are connected by a connecting rod 39. When the mounting groove 312 is working, the cooperation between the protrusion 37 and the groove 38 buffers the vibration generated by the mounting groove 312, thereby reducing the impact of the vibration generated by the mounting groove 312 on the light-emitting component 20. It should be noted that limit blocks are provided at both ends of the protrusion 37 to prevent the cold block 31 and the first fan 34 from overtravel.

[0035] Furthermore, a coolant is disposed within the second through hole 311, and the coolant is in the form of granular particles. The coolant contacts the inner wall of the second through hole 311. When hot air flows through the second through hole 311, the hot air contacts the coolant and exchanges heat with the coolant, thereby increasing the heat exchange area and improving the heat dissipation effect. An isolation net 35 is disposed at both ends of the second through hole 311. The mesh diameter of the isolation net 35 is smaller than that of the coolant to prevent the coolant from flowing out of the second through hole 311. Optionally, the coolant is made of quartz glass, which has excellent thermal conductivity.

[0036] The cooling block 31 is connected to the first fan 34 via a connecting rod 39. When the first fan 34 is working, the vibration generated by the first fan 34 drives the cooling block 31 to vibrate, and at the same time drives the cooling element to vibrate, thereby changing and extending the path of the hot air in the cooling element gap when passing through the second through hole 311, thereby increasing the residence time of the hot air in the second through hole 311, increasing the heat exchange efficiency, and improving the heat dissipation effect.

[0037] Furthermore, a third through hole 42 is provided on the mounting plate 40, and a heat conducting plate 36 is embedded in the third through hole 42. The upper end surface of the heat conducting plate 36 is in contact with the circuit board 21, and the lower end surface of the heat conducting plate 36 is in contact with the cold block 31. The connection line of the plurality of lamp beads 22 is on the same straight line, and the vertical plane where the connection line of the lamp beads 22 is located passes through the third through hole 42. The heat generated by some of the lamp beads 22 is transferred to the circuit board 21, and the heat of the circuit board 21 is transferred to the heat conducting plate 36, and the heat conducting plate 36 then transfers the heat to the cold block 31, and dissipates it to the outside air through the cooling plate 32 and the radiator 33. Through the above technical solution, the heat on the upper surface of the circuit board 21 is dissipated into the air of the first cavity, and the heat on the lower surface of the circuit board 21 is transferred to the heat conducting plate 36, thereby achieving heat dissipation of the upper and lower surfaces of the circuit board 21, greatly improving the heat dissipation effect.

[0038] Furthermore, a second fan (not shown) is provided on the outer surface of the housing 10 and is aligned with the radiator 33 to enhance the heat dissipation effect of the radiator 33 .

[0039] Furthermore, a mounting bracket 14 is provided on the lower end surface of the housing 10 for mounting on a wall.

[0040] The utility model patent discloses a strong heat dissipation wall washer lamp, and the specific implementation method is as follows: the light-emitting component 20 is located in the closed inner cavity of the shell 10, which can play a role in waterproofing and dustproofing. During heat dissipation, the cold block 31 exchanges heat with the hot air in the inner cavity of the shell 10, and the heat of the hot air is transferred to the cold block 31; the cooling surface of the cooling plate 32 absorbs the heat of the cold block 31, and transfers the heat to the radiator 33 through the heat dissipation surface, and the radiator 33 dissipates the heat into the air. The strong heat dissipation wall washer lamp of the utility model absorbs the heat from the inner cavity of the shell 10 through the cooling plate 32. Compared with the existing heat dissipation method of using natural wind to dissipate heat, it can greatly enhance the heat dissipation effect of the wall washer lamp. The shell 10 has no vents, which can greatly improve the waterproof and dustproof effect.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein.
