Description

Technical Field

[0001] The present application relates to the field of lighting equipment, and in particular to a track spotlight housing structure with high structural strength. Background Art

[0002] Track spotlights are widely used for lighting in shopping malls, hotels, windows and other places. They are mostly aluminum alloy shells with built-in LED light sources. They are colorful, environmentally friendly and energy-saving, light and simple, and beautiful. When used, they are installed on tracks or directly on the ceiling or wall, which can solve the basic lighting and highlight the lighting requirements of key projection.

[0003] At present, after long-term use, the internal light source of the track spotlight will emit a large amount of heat, which will cause thermal shock to the lamp body structure, thereby causing looseness and displacement between various components, affecting the lighting effect and reducing the service life of the lamp body. Utility Model Content

[0004] In order to improve the lighting effect and service life of the track spotlight, the present application provides a track spotlight housing structure with high structural strength.

[0005] The present application provides a track spotlight housing structure with high structural strength, which adopts the following technical solution:

[0006] A track spotlight housing structure with high structural strength comprises an outer shell and a light source. The outer shell is hollow inside and open at the lower end. The light source is arranged on the inner side wall of the outer shell. A plurality of exhaust holes are opened on the top of the outer shell. A plurality of ventilation holes are opened on the side wall of the outer shell close to the light source.

[0007] By adopting the above technical solution, the heat emitted by the light source is exchanged with the air. The air rises after being heated and is then discharged from the exhaust holes on the top of the shell. The cold air outside the shell enters the shell from the ventilation holes, thereby achieving continuous cooling of the inside of the shell, improving the problem of thermal shock caused by the heat generated by the light source to the lamp body structure, and effectively improving the lighting effect and service life of the track spotlight.

[0008] Optionally, the shell includes a top cover, an elastic card and a sleeve, the exhaust hole is opened on the top cover, the elastic card is arranged on the top cover, the sleeve is provided with a groove for the elastic card to be inserted, and the ventilation hole is opened on the sleeve.

[0009] By adopting the above technical solution, the staff first presses the elastic card in the direction away from the sleeve, then moves the sleeve close to the top cover, and then releases the elastic card so that the elastic card is stuck in the groove, and the assembly of the shell is completed. The split shell structure makes it easy to disassemble and assemble the shell, and conveniently repair and replace the light source.

[0010] Optionally, the elastic card is provided with an inclined surface, and the inclined surface is used to abut against the sleeve when the sleeve is close to the top cover to drive the elastic card to move away from the sleeve to make way.

[0011] By adopting the above technical solution, when the staff moves the sleeve close to the top cover, the sleeve abuts against the inclined surface on the elastic card, thereby driving the elastic card to move away from the sleeve to make way. As the sleeve continues to move, the sleeve no longer abuts against the inclined surface, and the elastic card resets and gets stuck in the groove, eliminating the process of the staff manually pressing the elastic card, thereby improving the convenience of assembling the shell.

[0012] Optionally, a support assembly for supporting the sleeve is provided on the inner side wall of the sleeve, and the support assembly includes a support rib and a disc. A plurality of the support ribs are circumferentially spaced apart on the inner side wall of the sleeve, and the disc is provided on a plurality of the support ribs.

[0013] By adopting the above technical solution, the disc supports the multiple supporting ribs, and the multiple supporting ribs support the sleeve, thereby improving the structural strength of the sleeve. In addition, channels for the circulation of hot air are formed between the multiple supporting ribs to guide the outflow of hot air and improve the stability of the hot air discharge sleeve.

[0014] Optionally, transition arcs are provided on the multiple supporting ribs at the ventilation holes, and the transition arcs extend in a direction away from the top cover.

[0015] By adopting the above technical solution, the transition arc connects the multiple supporting ribs at the ventilation holes, improves the integrity of the multiple supporting ribs at the ventilation holes, and thus compensates for the structural strength lost at the ventilation holes of the sleeve, and the transition arc extending away from the top cover can guide the cold air entering from the ventilation holes, so that the cold air can flow downward more and better exchange heat with the heat in the sleeve.

[0016] Optionally, the support ribs are covered with heat-conducting metal.

[0017] By adopting the above technical solution, the heat-conducting metal absorbs the heat in the sleeve, and then discharges it with the air flowing between adjacent supporting ribs, so that the heat in the sleeve can be better discharged.

[0018] Optionally, the light source includes a lamp body, a mounting ring and an elastic positioning piece, the lamp body abuts on the disc, the mounting ring abuts on the lamp body, a positioning groove is provided on the sleeve, and the elastic positioning piece is arranged on the mounting ring and is used to be clamped to the side wall of the positioning groove.

[0019] By adopting the above technical solution, the staff first abuts the lamp body against the disc, then moves the mounting ring towards the lamp body, and presses the elastic positioning piece to deform the elastic positioning piece. After the mounting ring abuts against the lamp body, the elastic positioning piece is released, and the elastic positioning piece recovers its deformation and is stuck in the positioning groove, so that the lamp body can be installed on the sleeve, which improves the convenience of installing the light source into the sleeve. Subsequently, the staff pulls the elastic positioning piece out of the positioning groove, and then removes the mounting ring and the lamp body.

[0020] Optionally, the plurality of ventilation holes are circumferentially spaced apart in groups on the outer side wall of the sleeve, and one transition arc is provided on the plurality of supporting ribs at each group of ventilation holes, and the transition arc extends in a direction close to the center of the disc.

[0021] By adopting the above technical solution, when the staff installs the lamp body on the disc, the parts of the multiple transition arcs extending toward the center of the disc can guide the lamp body, thereby improving the accuracy of the staff in moving the lamp body onto the disc.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The air rises after being heated, and then is discharged from the exhaust holes on the top of the shell. The cold air outside the shell enters the shell from the vents, thereby achieving continuous cooling inside the shell, improving the problem of heat shock to the lamp body caused by the heat generated by the light source, and effectively improving the lighting effect and service life of the track spotlight;

[0024] 2. The sleeve abuts against the inclined surface on the elastic card, thereby driving the elastic card to move away from the sleeve to make way. As the sleeve continues to move, the sleeve no longer abuts against the inclined surface, and the elastic card is reset and stuck in the groove, eliminating the process of manually pressing the elastic card by the staff, thereby improving the convenience of assembling the shell;

[0025] 3. The disc supports the multiple supporting ribs, which in turn support the sleeve, thereby improving the structural strength of the sleeve. In addition, channels for the circulation of heating air are formed between the multiple supporting ribs to guide the outflow of hot air and improve the stability of the hot air discharge sleeve.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a track spotlight housing structure with high structural strength.

[0033] Reference Figure 1 , Figure 2 The track spotlight housing structure with high structural strength includes an outer shell 1 and a light source 2. The outer shell 1 is hollow inside and open at the lower end. The light source 2 is installed on the inner wall of the outer shell 1. The light source 2 is used to be connected to an external power supply to provide lighting. A plurality of exhaust holes 11 are opened on the top of the outer shell 1, and a plurality of ventilation holes 12 are opened on the side wall of the outer shell 1 near the light source 2.

[0034] When the light source 2 emits light to provide lighting, the light source 2 generates heat, and the heat emitted by the light source 2 exchanges heat with the air. After being heated, the air rises and is discharged from the multiple exhaust holes 11 on the top of the shell 1, and then the cold air outside the shell 1 enters the inside of the shell 1 from the ventilation holes 12, and continues to exchange heat with the heat in the shell 1, continuously cooling the inside of the shell 1, improving the problem of thermal shock caused by the heat generated by the light source 2 to the structure of the lamp body 21, and effectively improving the lighting effect and service life of the guide track spotlight.

[0035] Reference Figure 1 , Figure 2The housing 1 includes a top cover 13, an elastic card 14 and a sleeve 15. A plurality of exhaust holes 11 are provided on the top cover 13. A plurality of elastic cards 14 are circumferentially installed on the bottom wall of the top cover 13. An inclined surface 141 is provided on the side of the elastic card 14 away from the top cover 13 and close to the sleeve 15. The inclined surface 141 is used to abut against the sleeve 15 when the sleeve 15 is close to the top cover 13, so as to drive the elastic card 14 to move away from the sleeve 15 and make way. The elastic card 14 can be made of elastic materials such as plastic and stainless steel. In the present embodiment, the elastic card 14 is made of plastic. A groove 151 is provided on the sleeve 15. The groove 151 is used for the elastic card 14 to be inserted when the sleeve 15 abuts against the top cover 13. A plurality of ventilation holes 12 are provided on the side wall of the sleeve 15. In the present embodiment, the outer wall of the sleeve 15 has a plurality of edges to improve the aesthetics of the sleeve 15.

[0036] When assembling the housing 1, the staff moves the sleeve 15 toward the top cover 13. The sleeve 15 abuts against the inclined surface 141 on the elastic card 14 in the process of approaching the top cover 13. The elastic card 14 moves away from the sleeve 15 under the extrusion to make way. Then the sleeve 15 continues to move until it abuts against the top cover 13. At this time, the groove 151 on the sleeve 15 is opposite to the elastic card 14, and the sleeve 15 no longer abuts against the inclined surface 141 on the elastic card 14. The elastic card 14 recovers. The sleeve 15 is positioned and installed on the top cover 13 by the elastic card 14 and the side wall of the groove 151, which effectively improves the convenience for the staff to assemble the shell 1. In addition, the split shell 1 structure allows the staff to pull the elastic card 14 out of the groove 151 to remove the sleeve 15 from the top cover 13 when the light source 2 in the shell 1 needs to be repaired or replaced.

[0037] Reference Figure 3 , Figure 4 A support assembly 3 is installed on the inner wall of the sleeve 15. The support assembly 3 is used to support the side wall of the sleeve 15. The support assembly 3 includes a support rib 31 and a disc 32. A plurality of support ribs 31 are installed on the inner wall of the sleeve 15. The plurality of support ribs 31 are circumferentially spaced on the inner wall of the sleeve 15. The disc 32 is installed at one end where the plurality of support ribs 31 are close to each other. In this embodiment, a plurality of through holes are opened on the disc 32 to facilitate the hot air to rise through the disc 32.

[0038] The disc 32 supports the multiple supporting ribs 31, and then the multiple supporting ribs 31 support the side walls of the sleeve 15, so that the structural strength of the sleeve 15 can be improved. At the same time, a channel can be formed between the adjacent supporting ribs 31 and the disc 32 and the inner wall of the sleeve 15. When the air in the sleeve 15 rises due to the heat, the hot air can rise from the channel. The channel guides the circulation of the hot air in the sleeve 15, thereby improving the stability of the hot air when it rises and is discharged from the sleeve 15.

[0039] Reference Figure 3 , Figure 4 Each supporting rib 31 is covered with a heat-conducting metal, which may be a metal with good thermal conductivity such as copper or aluminum. In the present embodiment, the heat-conducting metal is copper.

[0040] Due to the good thermal conductivity of the heat-conducting metal, the heat-conducting metal can exchange heat with the heat generated by the light source 2. When the air rises between adjacent supporting ribs 31, the air further exchanges heat with the heat-conducting metal before being discharged, thereby increasing the heat discharge speed in the sleeve 15.

[0041] Reference Figure 2 , Figure 3 The light source 2 includes a lamp body 21, a mounting ring 22 and an elastic positioning piece 23. The lamp body 21 abuts against the end of the disc 32 away from the top cover 13. In this embodiment, the lamp body 21 is an LED lamp; the mounting ring 22 abuts against the lamp body 21. In this embodiment, an elastic locking piece 5 made of plastic is installed on the mounting ring 22. A guide surface inclined from top to bottom is provided on the side of the elastic locking piece 5 close to the lamp body 21 and away from the mounting ring 22. When the staff moves the mounting ring 22 in the direction close to the lamp body 21, the lamp body 21 abuts against the guide surface and the elastic locking piece 5 is moved. The elastic locking piece 5 is pushed open, and after the mounting ring 22 abuts against the lamp body 21, the elastic locking piece 5 recovers its deformation and is clamped on the lamp body 21, thereby improving the tightness of the connection between the mounting ring 22 and the lamp body 21; a positioning groove 152 is provided in an annular manner on the inner wall of the sleeve 15, and a plurality of elastic positioning pieces 23 are installed circumferentially at intervals on the mounting ring 22. The elastic positioning pieces 23 are used to be clamped onto the side wall of the positioning groove 152. In this embodiment, the elastic positioning piece 23 is away from the mounting ring 22 and is close to the inner side wall of the sleeve 15. A slope gradually inclined from top to bottom is provided on one side.

[0042] The staff first moves the mounting ring 22 close to the lamp body 21 so that the mounting ring 22 abuts against the lamp body 21. At this time, the elastic locking piece 5 on the mounting ring 22 locks the lamp body 21 on the mounting ring 22. Then the staff moves the mounting ring 22 towards the direction close to the disc 32. In the process of the mounting ring 22 approaching the disc 32, the sleeve 15 abuts against the inclined surface on the elastic positioning piece 23, driving the elastic positioning piece 23 to deform towards the center of the sleeve 15. After the lamp body 21 abuts against the disc 32, the elastic locking piece 5 on the mounting ring 22 locks the lamp body 21 on the mounting ring 22. The elastic positioning piece 23 is opposite to the positioning groove 152, and the elastic positioning piece 23 recovers its deformation and is stuck in the positioning groove 152. At this time, the lamp body 21 can be positioned and installed in the sleeve 15 through the abutment between the elastic positioning piece 23 and the side wall of the positioning groove 152, which improves the convenience for the staff to install the lamp body 21, and the staff can pull the elastic positioning piece 23 out of the positioning groove 152, and then remove the mounting ring 22 from the sleeve 15, which further improves the convenience for the staff to repair and replace the lamp body 21.

[0043] Reference Figure 3 , Figure 4 A plurality of ventilation holes 12 are circumferentially spaced apart in groups on the side wall of the sleeve 15, and a transition arc 4 is installed on a plurality of supporting ribs 31 at each group of ventilation holes 12. The transition arc 4 extends in a direction away from the top cover 13. The transition arc 4 gradually inclines in a direction close to the center of the disk 32 from a direction close to the top cover 13 to a direction away from the top cover 13, and the transition arc 4 extends in a direction close to the center of the disk 32.

[0044] The transition arc 4 connects the multiple supporting ribs 31 at each group of ventilation holes 12, thereby improving the integrity of the multiple supporting ribs 31 at the ventilation holes 12, and further improving the supporting effect of the multiple supporting ribs 31 at the ventilation holes 12 on the sleeve 15, making up for the structural strength lost at the sleeve 15 where the ventilation holes 12 are opened; and the transition arc 4 extending in the direction away from the top cover 13 can block and guide the cold air entering from the ventilation holes 12, so that the cold air flows downward more and then rises from the lower part of the sleeve 15, and better exchanges heat with the heat in the sleeve 15; at the same time, a guide groove is formed by the multiple transition arcs 4 at the multiple groups of ventilation holes 12. When the staff installs the lamp body 21 on the disk 32, the parts of the multiple multi-degree arcs extending in the direction close to the center of the disk 32 can guide the lamp body 21, thereby improving the accuracy of the staff in moving the lamp body 21 onto the disk 32.

[0045] The implementation principle of a track spotlight shell structure with high structural strength in an embodiment of the present application is as follows: when the lamp body 21 is powered on to emit light, the heat generated exchanges heat with the air in the sleeve 15, and is partially absorbed by the heat-conducting metal on the supporting ribs 31. The air rises after being heated, and exchanges heat with the heat-conducting metal during the rising process. The hot air is finally discharged from the exhaust holes 11 on the top cover 13, and the cold air outside the sleeve 15 enters the sleeve 15 from the ventilation holes 12, and then rises from the bottom of the sleeve 15 to the top, continuously cooling the interior of the sleeve 15 and the lamp body 21, thereby improving the problem of thermal shock caused by the heat generated by the light source 2 to the structure of the lamp body 21, and effectively improving the lighting effect and service life of the track spotlight.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
