Abstract
Description
Technical Field
[0001] This utility model relates to the field of lamp housing technology, and in particular to an aluminum alloy lamp housing. Background Technology
[0002] Aluminum alloy lamp housings are a common material for lamp enclosures, offering numerous advantages. Their lightweight nature facilitates installation and transportation, reducing the overall weight of the lamp. Simultaneously, aluminum alloy's high strength provides excellent protection for internal components such as the light source and circuitry, resisting external impacts. Its excellent heat dissipation effectively dissipates heat generated by the light source, extending its lifespan and maintaining stable lamp performance. Furthermore, aluminum alloy lamp housings are highly corrosion-resistant and, after special treatment, remain stable in harsh environments such as humid and acidic / alkaline conditions. In manufacturing, aluminum alloy lamp housings are formed through processes such as die casting and extrusion, allowing for the creation of complex shapes to meet the design requirements of various lamps.
[0003] When aluminum alloy lamp housings are used as part of a lighting fixture for heat dissipation during operation, the structure on the aluminum alloy lamp housing cannot directly contact the aluminum substrate. Heat is often transferred through multiple layers of media such as the aluminum substrate and thermally conductive adhesive. This long heat dissipation path can easily cause the junction temperature of the LED chip to rise.
[0004] Therefore, an aluminum alloy lamp housing is proposed to solve or alleviate the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an aluminum alloy lamp housing.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An aluminum alloy lamp housing includes a lamp strip housing with an opening on one side. The inner top surface of the lamp strip housing has several through holes penetrating its back side. A movable heat dissipation column is disposed in the through holes. One end of the heat dissipation column located inside the lamp strip housing is confined within the lamp strip housing, and a gentle slope is formed on the outer ring of this end of the heat dissipation column. Thermal grease is applied to the gentle slope. The end face of the heat dissipation column located on the inner ring of the gentle slope forms a contact surface. The end of the heat dissipation column away from the gentle slope penetrates the lamp strip housing to the outside.
[0008] Preferably, a plurality of heat dissipation supports are fixedly connected to one end of the heat dissipation column that extends to the outside of the lamp strip housing. The plurality of heat dissipation supports are spaced apart, and a heat dissipation channel is formed between adjacent heat dissipation supports.
[0009] Preferably, the inner ring of the through hole has an internal thread, the outer ring of the heat dissipation column has an external thread, and the through hole and the heat dissipation column are connected by the internal and external threads.
[0010] Preferably, an annular groove is formed on the outer ring of one end of the heat dissipation column located inside the lamp strip housing, and a retaining ring is embedded in the annular groove.
[0011] Preferably, the back of the light strip housing is fixedly connected to an outer heat dissipation strip assembly, a middle heat dissipation strip assembly located between the outer heat dissipation strip assemblies, an inner heat dissipation strip assembly located between the middle heat dissipation strip assemblies, and a central heat dissipation strip located between the inner heat dissipation strip assemblies. The length direction of the outer heat dissipation strip assembly, the middle heat dissipation strip assembly, the inner heat dissipation strip assembly, and the central heat dissipation strip is the same as the length direction of the light strip housing. The outer heat dissipation strip assembly, the middle heat dissipation strip assembly, the inner heat dissipation strip assembly, and the central heat dissipation strip are spaced apart in the width direction of the light strip housing. The outer heat dissipation strip assembly and the inner heat dissipation strip assembly are each in two groups and are located at both ends of the light strip housing. The number of middle heat dissipation strip assemblies is one, and the middle heat dissipation strip assembly is located between the two groups of outer heat dissipation strip assemblies and the two groups of inner heat dissipation strip assemblies. The through holes are opened on the light strip housing between the two groups of outer heat dissipation strip assemblies, the light strip housing between the two groups of inner heat dissipation strip assemblies, the light strip housing at both ends of the middle heat dissipation strip assembly, and the light strip housing at both ends of the central heat dissipation strip.
[0012] Preferably, the heat dissipation column, heat dissipation support strip, outer heat dissipation strip assembly, middle heat dissipation strip assembly, inner heat dissipation strip assembly, and central heat dissipation strip are all made of copper alloy.
[0013] Preferably, the back of the light strip housing is fixedly connected to two side extension strips located outside the outer heat dissipation strip assembly, and the opening edge of the light strip housing is fixedly connected to a limit clip.
[0014] This utility model has the following beneficial effects:
[0015] In use, this invention involves first applying thermal grease to the sloping surface of the heat dissipation column, then installing the lamp plate into the lamp strip housing, and reversing the lamp plate to flatten its edges against the retaining strip. The heat dissipation column is then manually rotated, and its length into the lamp strip housing is adjusted via the threaded connection until it contacts the back of the lamp plate. The thermal grease increases the thermally conductive contact surface, ensuring the heat dissipation column can contact and dissipate heat even if the back of the lamp plate is uneven. The retaining ring prevents the heat dissipation column from detaching, and the spaced-apart heat dissipation strips increase the heat dissipation area without obstructing airflow.

[0028] An aluminum alloy lamp housing, such as Figures 1 to 4 As shown, the lamp strip housing 1 includes an opening on one side. The inner top surface of the lamp strip housing 1 has several through holes 7 extending through its back. A movable heat dissipation column 8 is provided in the through holes 7. One end of the heat dissipation column 8 located inside the lamp strip housing 1 is confined within the lamp strip housing 1, and a gentle slope 9 is provided on the outer ring of this end of the heat dissipation column 8. Thermal grease is applied to the gentle slope 9. The end face of the heat dissipation column 8 located in the inner ring of the gentle slope 9 forms a contact surface 10. The end of the heat dissipation column 8 away from the gentle slope 9 extends through the lamp strip housing 1 to the outside.
[0029] like Figure 2 and Figure 4 As shown, a plurality of heat dissipation supports 13 are fixedly connected to one end of the heat dissipation column 8 that extends to the outside of the lamp strip housing 1. The plurality of heat dissipation supports 13 are spaced apart, and a heat dissipation channel is formed between adjacent heat dissipation supports 13. The inner ring of the through hole 7 is provided with an internal thread, and the outer ring of the heat dissipation column 8 is provided with an external thread. The through hole 7 and the heat dissipation column 8 are connected by the internal thread and the external thread. The outer ring of the end of the heat dissipation column 8 located inside the lamp strip housing 1 is provided with an annular groove 11, and a retaining ring 12 is embedded in the annular groove 11.
[0030] like Figure 1 and Figure 3As shown, the back of the lamp strip housing 1 is fixedly connected to an outer heat dissipation strip assembly 3, a middle heat dissipation strip assembly 5 located between the outer heat dissipation strip assembly 3, an inner heat dissipation strip assembly located between the middle heat dissipation strip assembly 5, and a central heat dissipation strip 6 located between the inner heat dissipation strip assemblies. The length direction of the outer heat dissipation strip assembly, the middle heat dissipation strip assembly 5, the inner heat dissipation strip assembly, and the central heat dissipation strip 6 is the same as the length direction of the lamp strip housing 1. The outer heat dissipation strip assembly, the middle heat dissipation strip assembly 5, the inner heat dissipation strip assembly, and the central heat dissipation strip 6 are spaced apart in the width direction of the lamp strip housing 1. The outer heat dissipation strip assembly and the inner heat dissipation strip assembly are each in two groups and are located at both ends of the lamp strip housing 1, respectively. The middle heat dissipation strip assembly... The quantity of 5 is a group, and the middle heat dissipation strip group 5 is located between the two groups of outer heat dissipation strip groups and the inner heat dissipation strip group. The through hole 7 is opened on the lamp strip shell 1 between the two groups of outer heat dissipation strip groups, the lamp strip shell 1 between the two groups of inner heat dissipation strip groups, the lamp strip shell 1 at both ends of the middle heat dissipation strip group 5, and the lamp strip shell 1 at both ends of the center heat dissipation strip 6. The back of the lamp strip shell 1 is fixedly connected to two side extension strips 2 located outside the outer heat dissipation strip group 3. The opening edge of the lamp strip shell 1 is fixedly connected to the limit clip strip 14. The side extension strip 2, heat dissipation column 8, heat dissipation support strip 13, outer heat dissipation strip group, middle heat dissipation strip group 5, inner heat dissipation strip group, and center heat dissipation strip 6 are all made of copper alloy.
[0031] In practical use, this invention first applies thermal grease to the gentle slope 9 of the heat dissipation column 8. Then, the lamp plate is installed into the lamp strip housing 1. Next, the lamp plate is reversed and leveled so that its edge abuts against the limiting strip 14, thus restricting the lamp plate and preventing it from leaving the lamp strip housing 1. At this point, the heat dissipation column 8 can be manually rotated. The heat dissipation column 8 is threadedly connected to the inner thread of the through hole 7, thereby adjusting the length of the heat dissipation column 8 inside the lamp strip housing 1. This ensures that the heat dissipation column 8 abuts against the back of the lamp plate, allowing the contact surface 10 to contact the lamp plate. The contact surface 10 and the gentle slope 9 ensure sufficient contact area between the heat dissipation column 8 and the back of the lamp plate, preventing heat loss. The excessive influence of column 8 on the structure of the back of the lamp panel, while the thermal grease on the gentle slope 9 can further increase the thermal contact area between the heat dissipation column 8 and the lamp panel. Even if the back of the lamp panel is uneven due to the electrical structure, the position of the heat dissipation column 8 can limit the contact between the heat dissipation column 8 and the lamp panel, and then transfer heat to the outside. In this process, the retaining ring 12 ensures that the heat dissipation column 8 will not detach from the lamp strip shell 1. The spaced outer heat dissipation strip group, middle heat dissipation strip group 5, inner heat dissipation strip group, and central heat dissipation strip 6 ensure that the heat dissipation area is increased when the back of the lamp strip shell 1 dissipates heat, while not affecting the air flow, ensuring that the air can circulate and dissipate heat when flowing from all directions.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
