Description

Technical Field

[0001] The present application relates to the field of track spotlights, and in particular to a track spotlight with a stable structure. Background Art

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

[0003] The common track spotlights on the market usually include a power box, a track head and a direction adjustment rod set on the power box, a lamp body shell rotatably set on the direction adjustment rod, a heat sink set in the lamp body shell, a light source and a lens assembly. The light source usually includes a heat dissipation base, a PCB board and a light-emitting chip set on the heat dissipation base. The lens assembly can concentrate the light emitted by the light source into a small area, making the light more concentrated, thereby making the brightness stronger, so that the light of the spotlight can play a good role in terms of light angle, brightness and color temperature. The radiator of the spotlight usually adopts a mounting tube and a plurality of heat sinks arranged around the mounting tube. The plurality of heat sinks are arranged at intervals to better conduct heat and dissipate heat.

[0004] However, when the track spotlight is working, the light source will emit a lot of heat, and the internal space of the lamp body shell is small. When the track spotlight is working for a long time, the heat dissipation efficiency of the heat sink is usually difficult to adapt to the heat generated by the light source. The heat accumulated in the lamp body shell for a long time will cause the internal structures of the lamp body shell to expand and loosen, especially when used in a shaking environment (such as marine use), which will shorten the service life of the spotlight. Utility Model Content

[0005] In order to improve the structural stability and service life of a track spotlight, the present application provides a track spotlight with a stable structure.

[0006] The present application provides a track spotlight with a stable structure, which adopts the following technical solution:

[0007] A structurally stable track spotlight comprises a spotlight housing, in which a heat sink, a light source and a lens are sequentially arranged, and an opening cover at one end of the spotlight housing away from the lens is provided with a ventilated back cover; the heat sink comprises a heat sink plate fixedly connected to the inner wall of the spotlight housing and a plurality of reinforcing rib plates, the plurality of reinforcing rib plates are arranged at intervals around the center of the heat sink and are vertically fixed to the heat sink, the heat sink is provided with a plurality of heat dissipation holes, the plurality of heat dissipation holes are respectively located between two adjacent reinforcing rib plates, and the inner edge contour of the heat dissipation holes is shuttle-shaped.

[0008] By adopting the above technical solution, the heat generated by the light source flows to the ventilation rear cover through multiple heat dissipation holes, and the heat transfer is accelerated by multiple reinforcing ribs to improve the heat dissipation efficiency. At the same time, through the positional connection relationship between the heat dissipation plate and the multiple reinforcing ribs and the spotlight housing, when the heat accumulates in the spotlight housing and is not discharged, the spotlight housing can be supported to prevent expansion and deformation, thereby improving the structural stability of the track spotlight; and through the support and shaping of the heat dissipation plate by multiple reinforcing ribs, and the inner edge contour of the heat dissipation hole is shuttle-shaped, the opening area of ​​the heat dissipation hole can be as large as possible when the heat dissipation plate is not easily deformed, so as to improve the heat dissipation efficiency, thereby reducing the possibility of expansion and loosening of the spotlight housing or its internal structure due to heat accumulation and shaking environment, so as to improve the service life of the track spotlight.

[0009] Optionally, a supporting cylinder is vertically fixed at the center of the heat dissipation plate, and a plurality of reinforcing rib plates are simultaneously fixedly connected to the outer wall of the supporting cylinder.

[0010] By adopting the above technical solution, the supporting cylinder can more stably and firmly fix the multiple reinforcing ribs to the heat sink and the inner wall of the spotlight housing. At the same time, the supporting cylinder can bear and absorb the force from the reinforcing ribs to a certain extent through its arc outer wall, thereby making the internal structure of the spotlight housing more stable, thereby further improving the structural stability and service life of the guide spotlight.

[0011] Optionally, two inner support plates which are perpendicularly arranged and fixed to each other are arranged in the support tube, and the two inner support plates are fixedly connected to the inner wall of the support tube.

[0012] By adopting the above technical solution, the two inner support plates can prevent the supporting cylinder from being deformed due to the force from the reinforcing rib plate, so as to further make the internal structure of the spotlight housing more stable and improve the structural stability and service life of the track spotlight.

Since hot air moves upward and cold air moves downward, the heat generated by the light source can be dissipated more quickly through the enhanced cooling channel and the first vent, and external cold air will enter the spotlight housing through the enhanced cooling channel and the first vent to further improve the heat dissipation efficiency and further reduce the possibility of expansion and loosening of the spotlight housing or its internal structure due to heat accumulation and shaking environment, so as to improve the service life of the track spotlight.

[0015] Optionally, at least one auxiliary heat dissipation channel is further provided on the outer edge of the heat dissipation plate, and at least one group of second air vents is provided on the side wall of the spotlight housing, and at least one group of second air vents is respectively connected to at least one auxiliary heat dissipation channel.

[0016] By adopting the above-mentioned technical solution, the heat generated by the light source can be dissipated to the outside more quickly through at least one auxiliary heat dissipation channel and a second vent, thereby further improving the heat dissipation efficiency and further reducing the possibility of expansion and loosening of the spotlight housing or its internal structure due to heat accumulation and jitter environment, thereby increasing the service life of the track spotlight.

[0018] By adopting the above technical solution, the support plate and the secondary support plate form a reinforced structure at the auxiliary heat dissipation channel, which can make the edge of the auxiliary heat dissipation channel less likely to be deformed due to heat accumulation and shaking environment, so that the structural strength of the guide track spotlight at the auxiliary heat dissipation channel will not be reduced.

[0019] Optionally, the light source is mounted on the spotlight housing via a base, the base is provided with a lamp cup for focusing light, the small end of the lamp cup is fixed to the base and the large end is located on the side of the base away from the heat sink, and the lens is detachably arranged on the large end of the lamp cup via a snap fastener.

[0020] By adopting the above technical solution, the light source is stably arranged in the spotlight housing through the base, and the light emitted by the light source is more concentrated and brighter through the lamp cup and the lens, thereby improving the illumination effect of the track spotlight. In addition, the lens can be stably installed on the lamp cup through the buckle, and can also be disassembled and installed, so as to facilitate the inspection and replacement of the light source.

[0021] Optionally, the fastener includes a snap ring and a buckle ring, the snap ring is coaxially and fixedly arranged on the large end opening of the lamp cup, the buckle ring is coaxially covered on the snap ring, the snap ring is fixedly connected with at least two snap plates, the snap plates are made of elastic material, the snap plates are fixedly connected with abutment blocks, and the abutment blocks of at least two of the snap plates are in contact with the lower side wall of the snap ring; the lens is clamped between the snap ring and the buckle ring.

[0022] By adopting the above technical solution, the abutment blocks of at least two of the snap-fit ​​plates abut against the lower side wall of the snap-fit ​​ring, so that the snap-fit ​​ring is stably covered on the snap-fit ​​ring to tightly clamp and fix the lens. At the same time, by pulling the snap-fit ​​plate, the abutment block no longer abuts against the snap-fit ​​ring, so as to achieve a detachable connection.

[0023] Optionally, a chamfer is provided at the lower end of the abutment block, and an inclined surface of the chamfer faces the buckle ring.

[0024] By adopting the above technical solution, the guide angle can make the buckling of the buckling ring smoother and more convenient than the snap ring, thereby improving the operational efficiency of the detachable connection.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The present application embodiment discloses a track spotlight with a stable structure. Figure 1 and Figure 2The track spotlight with a stable structure includes a power box 9, a track head 91, a direction adjustment support rod 92 and a spotlight housing 1. The track head 91 is arranged at one end of the power box 9, and the direction adjustment support rod 92 is arranged on the lower side wall of the power box 9 and is arranged at the same end as the track head 91. The spotlight housing 1 is cylindrical, and a rotation groove 12 is provided at the edge of the opening at one end of the spotlight housing 1. The direction adjustment support rod 92 is located in the rotation groove 12 and is rotatably connected to the spotlight housing 1. A rotation guide angle 921 is provided on the side wall of the direction adjustment support rod 92 facing the spotlight housing 1, so that the spotlight housing 1 can rotate relative to the direction adjustment support rod 92 and limit the rotation angle within a certain direction and range. At the same time, there is an interference fit between the direction adjustment support rod 92 and the wall of the rotation groove 12, so that the angle can be adjusted only by pulling with force, and the angle can be stably maintained after the angle is adjusted.

[0037] Reference Figure 1 The spotlight housing 1 is provided with a ventilation rear cover 11 at the edge of the opening near the direction adjustment support rod 92, and the ventilation rear cover 11 is provided with an escape opening 111 to adapt to the direction adjustment support rod 92. The spotlight housing 1 is provided with a heat sink 2, a light source 3 and a lens 31, and the heat sink 2, the light source 3 and the lens 31 are arranged away from the ventilation rear cover 11 in sequence.

[0038] Reference Figure 3 The heat sink 2 includes a heat sink 21 and a plurality of reinforcing ribs 22. The heat sink 21 is in the shape of a circular plate. The heat sink 21 is fixedly connected to the inner wall of the spotlight housing 1 and is perpendicular to the axis of the spotlight housing 1. The plurality of reinforcing ribs 22 are all in a rectangular plate structure. The short sides of one side of the plurality of reinforcing ribs 22 are all fixed to the side wall of the heat sink 21 close to the ventilation rear cover 11. The plurality of reinforcing ribs 22 are perpendicular to the heat sink 21. The plurality of reinforcing ribs 22 are arranged around and spaced at the center of the heat sink 21. The heat sink 21 is provided with a plurality of heat dissipation holes 211, and the plurality of heat dissipation holes 211 are respectively located between two adjacent reinforcing ribs 22. The inner edge contours of the plurality of heat dissipation holes 211 are all in a shuttle shape, and the length directions of the plurality of heat dissipation holes 211 are all toward the center of the heat sink 21.

[0039] The heat generated by the light source 3 flows to the ventilated rear cover 11 through the multiple heat dissipation holes 211, and the heat transfer is accelerated through the multiple reinforcing ribs 22 to improve the heat dissipation efficiency. At the same time, through the positional connection relationship between the heat dissipation plate 21 and the multiple reinforcing ribs 22 and the spotlight housing 1, when the heat is accumulated in the spotlight housing 1 and not discharged, the spotlight housing 1 can be supported to prevent expansion and deformation, thereby improving the structural stability of the track spotlight; and through the support and shaping of the heat dissipation plate 21 by the multiple reinforcing ribs 22, and the inner edge contour of the heat dissipation hole 211 is shuttle-shaped, the opening area of ​​the heat dissipation hole 211 can be as large as possible when the heat dissipation plate 21 is not easily deformed, so as to improve the heat dissipation efficiency, thereby reducing the possibility of expansion and loosening of the spotlight housing 1 or its internal structure due to heat accumulation and shaking environment, so as to improve the service life of the track spotlight.

[0040] Reference Figure 3 In order to further improve the structural stability of the track spotlight, a support cylinder 4 is vertically fixed at the center of the heat dissipation plate 21, and multiple reinforcing ribs 22 are simultaneously fixedly connected to the outer wall of the support cylinder 4. Two inner support plates 41 are arranged in the support cylinder, and the two inner support plates 41 are vertically penetrated and fixed to each other, and the two inner support plates 41 are fixedly connected to the inner wall of the support cylinder.

[0041] The support cylinder 4 can make the multiple reinforcing ribs 22 more stably and firmly fixed to the heat sink 21 and the inner wall of the spotlight housing 1, and the support cylinder 4 can bear and absorb the force from the reinforcing ribs 22 to a certain extent through its arc outer wall, so as to make the internal structure of the spotlight housing 1 more stable. At the same time, the two inner support plates 41 can prevent the support cylinder 4 from being deformed due to the force from the reinforcing ribs 22, so as to further make the internal structure of the spotlight housing 1 more stable, and improve the structural stability and service life of the track spotlight.

[0042] Reference Figure 3 and Figure 4 , since the illumination angle of the track spotlight is usually adjustable, that is, the spotlight housing 1 is rotated and adjusted relative to the power box 9 and the track head 91, and during the adjustment process of the angle of the spotlight housing 1, one side wall of the spotlight housing 1 is usually fixedly set to face upward, so the outer edge of the heat sink 21 close to its upward rotation direction is the edge side close to the spotlight housing 1 facing upward. In order to further improve the heat dissipation efficiency, a reinforced cooling channel 5 is also provided on the outer edge of the heat sink 21 close to its upward rotation direction. The long side of the reinforced cooling channel 5 is arc-shaped, and reinforcing ribs 22 are respectively provided at both ends of the reinforced cooling channel 5. In addition, a reinforcing rib 22 is also provided across the reinforced cooling channel 5, so that the edge of the reinforced cooling channel 5 is not easily deformed. A plurality of first vents 51 are provided on the side wall of the spotlight housing 1, and the plurality of first vents 51 are all connected to the reinforced cooling channel 5.

[0043] According to common knowledge, hot air moves upward and cold air moves downward, so the heat generated by the light source 3 can be dissipated more quickly through the enhanced cooling channel 5 and the first air vent 51, and external cold air will enter the spotlight housing 1 through the enhanced cooling channel 5 and the first air vent 51 to further improve the heat dissipation efficiency and further reduce the possibility of expansion and loosening of the spotlight housing 1 or its internal structure due to heat accumulation and jitter environment, so as to increase the service life of the guide spotlight.

[0044] Reference Figure 3 and Figure 4 In order to further improve the heat dissipation efficiency, an auxiliary heat dissipation channel 6 is also provided on the outer edge of the heat dissipation plate 21, and the long side of the auxiliary heat dissipation channel 6 is arc-shaped. A group of second vents 61 is provided on the side wall of the spotlight housing 1, and the group of second vents 61 includes a plurality of second vents 61, and the plurality of second vents 61 are all connected to the auxiliary heat dissipation channel 6. The auxiliary heat dissipation channel 6 is located between the two reinforcing ribs 22, and a support plate 62 is fixedly connected between the two reinforcing ribs 22. The support plate 62 is arranged perpendicular to the heat dissipation plate 21, and the support plate 62 extends along the long side of the auxiliary heat dissipation channel 6. A secondary support plate 63 is fixedly connected between the support plate 62 and the side wall of the spotlight housing 1, and the secondary support plate 63 spans the auxiliary heat dissipation channel 6 and is perpendicular to the support plate 62.

[0045] The heat generated by the light source 3 can also be dissipated to the outside more quickly through the auxiliary heat dissipation channel 6 and the second vent hole 61, thereby further improving the heat dissipation efficiency and further reducing the possibility of the spotlight housing 1 or its internal structure expanding and loosening due to heat accumulation and a shaking environment, so as to increase the service life of the track spotlight. The support plate 62 and the secondary support plate 63 form a reinforcement structure at the auxiliary heat dissipation channel 6, which can make the edge of the auxiliary heat dissipation channel 6 less likely to deform due to heat accumulation and a shaking environment, so that the structural strength of the track spotlight at the auxiliary heat dissipation channel 6 will not be reduced.

[0046] Reference Figure 4 and Figure 5 , the light source component 3 is generally a PCB board or a light-emitting chip. In the embodiment of the present application, the light source component 3 is a PCB board. A side wall of the heat sink 21 close to the lens 31 is fixedly connected to a base 7, and the light source component 3 is mounted on the base 7. The base 7 is provided with a lamp cup 71, and the lamp cup 71 is used to focus the light emitted by the light source component 3. The cross-sectional profile of the lamp cup 71 is trapezoidal, and the small end of the lamp cup 71 is fixedly provided on the base 7, and the light source component 3 is located in the small end opening of the lamp cup 71. The base 7 and the large end of the lamp cup 71 are located on the side of the base 7 close to the lens 31, and the lens 31 is detachably provided on the large end of the lamp cup 71 through the snap fastener 8.

[0047] Reference Figure 4 and Figure 5 The snap-fitting member 8 includes a snap-fitting ring 81 and a buckle ring 82. The snap-fitting ring 81 is fixedly connected to the edge of the large end opening of the lamp cup 71. The snap-fitting ring 81 is coaxially arranged with the lamp cup 71. The buckle ring 82 is coaxially covered with the snap-fitting ring 81. The buckle ring 82 is fixedly connected with three buckle plates 83. The three buckle plates 83 are arranged at intervals around the center of the buckle ring 82. The buckle plates 83 are made of plastic material. The buckle plates 83 are fixedly connected with abutment blocks 831. The abutment blocks 831 are rectangular structures. The abutment blocks 831 of the three buckle plates 83 all abut against the lower side wall of the snap-fitting ring 81. The lens 31 is clamped between the snap-fitting ring 81 and the buckle ring 82. A buckle guide angle 832 is provided at the lower end of the abutment block 831. The inclined surface of the buckle guide angle 832 faces the buckle ring 82.

[0048] The abutment blocks 831 of the three buckling plates 83 are all in contact with the lower side wall of the clamping ring 81, so that the buckling ring 82 is stably covered on the clamping ring 81 to tightly clamp and fix the lens 31. At the same time, by pulling the buckling plate 83, the abutment blocks 831 no longer abut against the clamping ring 81, so as to achieve a detachable connection. The buckling guide angle 832 can make the buckling of the buckling ring 82 relative to the clamping ring 81 smoother and more convenient, thereby improving the operating efficiency of the detachable connection.

[0049] Reference Figure 5 In order to install the lens 31 more stably, the buckle ring 82 is also fixedly connected to a stabilizing plate 84, and the stabilizing plate 84 is penetrated and threadedly connected with a tightening bolt 841, and the tightening bolt 841 abuts against the lamp cup 71. At the same time, two anti-slipping blocks 821 are also fixedly connected to the inner wall of the buckle ring 82. Since the cross-sectional profile of the lamp cup 71 is trapezoidal, the tightening bolt 841 abuts against the outer wall of the lamp cup 71, so that the buckle ring 82 can be more stably buckled on the clamping ring 81, and the two anti-slipping blocks 821 can prevent the lens 31 from sliding and protruding relative to the buckle ring 82, so as to more stably fix and install the lens 31.

[0050] The implementation principle of a track spotlight with a stable structure in the embodiment of the present application is as follows: the heat generated by the operation of the light source 3 flows to the ventilation rear cover 11 through the multiple heat dissipation holes 211, and the heat transfer is accelerated through the multiple reinforcing ribs 22 to improve the heat dissipation efficiency. At the same time, through the positional connection relationship between the heat dissipation plate 21 and the multiple reinforcing ribs 22 and the spotlight housing 1, when the heat is accumulated in the spotlight housing 1 and not discharged, the spotlight housing 1 can be supported to prevent expansion and deformation, thereby improving the structural stability of the track spotlight; and through the support and shaping of the heat dissipation plate 21 by the multiple reinforcing ribs 22, and the inner edge contour of the heat dissipation hole 211 is shuttle-shaped, the opening area of ​​the heat dissipation hole 211 can be as large as possible when the heat dissipation plate 21 is not easily deformed, so as to improve the heat dissipation efficiency, thereby reducing the possibility of expansion and loosening of the spotlight housing 1 or its internal structure due to heat accumulation and shaking environment, so as to improve the service life of the track spotlight.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
