Description

Track light fixture

This creation is about a luminaire, especially about a track luminaire.

The current indoor light source is divided into direct illumination or indirect illumination. For example, the recessed light is installed on the ceiling, and the light emitted by the recessed light is directly irradiated downward; the indirect illumination is to indirectly illuminate the light by means of reflection. Space, but in general, the brightness of indirect lighting is not as good as direct lighting.

Traditional recessed lights are embedded in the ceiling and project light from the ceiling to provide a fixed range of light. Since the light-emitting area provided by the recessed lamp is fixed and cannot be intentionally turned to a specific area to project light, recently, the lamp related industry has developed a steerable projection lamp to deliberately project light toward a specific area. However, such a projection lamp can only be steered at a fixed point and cannot be laterally displaced.

To this end, luminaire-related manufacturers have developed a laterally displaceable track light that provides lateral mobility to specific areas to provide more maneuverable lighting performance. However, regardless of whether the track light can have a steering function, the track light can only provide a fixed illumination angle, which cannot meet the needs of the user for different illumination purposes, and thus there are still inconveniences and disadvantages for the user.

One of the technical aspects of the present invention is to provide a track luminaire for solving the inconveniences and disadvantages mentioned in the prior art.

According to an embodiment of the present invention, the track light fixture comprises a lamp body, a connecting rod and a sliding seat. The lamp body comprises a heat dissipation base, a light-emitting element, an outer cover, a cover and a reflector cup element. The light emitting element is fixed to one end of the heat dissipation base. The outer cover is disposed at one end of the heat dissipation base. The cover is disposed at the other end of the outer cover opposite to the heat dissipation base. Here, the reflector cup element is detachably limited between the cover and the heat sink base. The sliding seat is electrically connected to the light emitting element for slidably assembling on a conductive track. One end of the connecting rod is movably engaged with the heat dissipating base, and the opposite end is connected to the sliding seat.

In one or more embodiments of the present invention, the reflector cup component includes a cup body, an accommodating space, a light exit port, an entrance port and an edge portion. The cup body is located in the outer cover member, and the cup body includes an accommodating space.

The edge portion is located at one end of the cup having a light exit opening, protrudes away from the light exit opening, and is sandwiched between the cover and the outer cover.

In one or more embodiments of the present creation, the track light fixture further includes a Light transmissive sheet. The transparent sheet covers the optical opening and is directly sandwiched between the cover and the edge portion.

In one or more embodiments of the present creation, the cup further comprises a surrounding The reflective inner wall of the accommodation space. The reflective inner wall is used to control the light exit angle of the light emitting element, for example, the light exit angle can be maintained at 15 degrees, 25 degrees, 45 degrees, or 60 degrees.

In one or more embodiments of the present creation, the outer cover comprises a wraparound Body, a cylindrical body and a plurality of concave holes. The cylindrical body has a through passage through which the cup body is accommodated. The surrounding body surrounds the cylindrical body and is defined between the cylindrical body An annular groove, and the cover is sleeved in the annular groove. The recessed holes are arranged in the annular groove at intervals.

In one or more embodiments of the present invention, the opposite ends of the surrounding body have a line that is parallel to the virtual axis of the body, and the closer to the connecting rod, the smaller the length of the connecting line.

In one or more embodiments of the present invention, the cover includes an annular body, an extension portion, and a plurality of protrusions. The annular body has an annular inner edge, and the annular inner edge surrounds a through hole coaxial with the light exit opening. The stacked light-transmissive sheets and the edge portions are sandwiched between the annular inner edge and the cylindrical body. The extension portion protrudes from the outside of one of the annular bodies in the same direction, protrudes into the annular groove, and surrounds the cylindrical body. The protrusions are arranged at intervals on one end surface of the extension portion opposite to the annular body for respectively inserting the recess holes in the annular groove.

In one or more embodiments of the present invention, the track light fixture further includes a universal joint set. The universal joint set includes a receiving groove and a screw member. The receiving groove is located at one end of the connecting rod. One end of the screw member is locked on the heat dissipation base, and the screw member has a spherical head at one end of the heat dissipation base. The spherical head can be integrally moved in the receiving groove. This end of the screw has a more twist-stop structure. The anti-rotation structure is used to limit the pivoting of the screw.

In one or more embodiments of the present invention, the other end surface of the heat dissipation base is provided with a plurality of heat dissipation fins.

Figure 3 is a partial cross-sectional view taken along line 3-3 of Figure 1.

Fig. 4 is a perspective view showing the outer cover and the cover of Fig. 2 at a relative viewing angle.

The spirit of the present invention will be clearly illustrated by the following description and detailed description. Those skilled in the art, after having understood the embodiments of the present invention, may be modified and modified by the techniques taught by the present invention, and do not deviate from the creation. The spirit and scope.

FIG. 1 is a perspective view of a rail light fixture 100 in accordance with an embodiment of the present invention. As shown in FIG. 1, the track fixture 100 includes a lamp body 200, a connecting rod 300, and a sliding seat 400. The connecting rod 300 connects the lamp body 200 and the sliding seat 400. The sliding seat 400 is slidably engaged on a conductive track R, and the electric power is supplied to the lamp body 200 via the electric wires housed in the connecting rod 300 to electrically connect the lamp body 200. In this way, since the conductive track R can be mounted on a general wall or a ceiling, and the conductive track R can be in a straight or curved pattern, the lamp body 200 can be moved by the sliding seat 400 along the track of the conductive track R. Displaces to a specific area and provides an illumination source for this particular area.

Fig. 2 is an exploded view of Fig. 1. As shown in FIG. 2, the lamp body 200 includes a heat dissipation base 210, a light emitting element 220, an outer cover member 230, a reflective cup member 240 and a cover 260. The opposite side of the heat sink base 210 A placement surface 211 and a plurality of heat dissipation fins 212 are respectively disposed. The heat dissipation fins 212 are erected on one side of the heat dissipation base 210 opposite to the surface 211. The light-emitting element 220 (for example, an LED integrated package, the Chip On Board) is fixed on the placement surface 211 and electrically connected to the sliding seat 400. One end of the outer cover 230 is sleeved on one end of the heat dissipation base 210 to cover the placement surface 211 and the light emitting element 220. The cover 260 is disposed at one end of the outer cover 230 opposite to the heat dissipation base 210. The reflector cup element 240 is removably limited between the cover 260 and the heat sink base 210.

Since the reflector cup element 240 can be easily and quickly removed from the rail luminaire 100, the user can arbitrarily change the reflector cup elements 240 of different exit angles in the track luminaire 100 according to requirements, so that the track lamp can provide different kinds of illuminating lights. The angle, in turn, meets the needs of the user for different lighting purposes.

More specifically, as shown in FIGS. 2 and 3, FIG. 3 is a partial cross-sectional view taken along line 3-3 of FIG. 1. The reflector cup element 240 includes a cup body 241. The cup body 241 has an accommodating space 242 and a reflective inner wall 243. The reflective inner wall 243 and the accommodating space 242 are both located in the cup body 241, and the reflective inner wall 243 completely surrounds the accommodating space 242. The accommodating space 242 is located in the cup body 241 and extends through the opposite ends of the cup body 241 in a longitudinal direction, so that the opposite ends of the cup body 241 respectively form a light exit opening 244 and a light entrance opening 246. Since the cup body 241 has a shape that gradually enlarges from the light entrance opening 246 toward the light exit opening 244, the diameter of the light exit opening 244 is larger than the diameter of the light entrance opening 246. The light exit port 244 and the light entrance port 246 are mutually connected to the accommodating space 242 and are coaxial with each other. The so-called coaxial means that the two have a common virtual axis A. The light entrance port 246 is interposed between the light emitting element 220 and the light exit port 244, so that the light emitting element 220 sequentially emits light toward the light entrance port 246 and the light exit port 244.

In addition, since the reflector cup element 240 cannot be stably located in the lamp body 200, the illuminating performance of the lamp body 200 is affected by the sway, so that the reflector cup element 240 can be more stably confined in the lamp body 200 and provided. The reflective cup element 240 further includes an edge portion 245. The edge portion 245 is located at one end of the cup 241 having the light exit opening 244 and extends away from the light exit opening 244 and surrounds the light exit opening 244. Thus, by the edge portion 245 being sandwiched between the cover 260 and the outer cover 230, the reflective cup member 240 is confined between the cover 260 and the heat dissipation base 210 and at a distance from the light-emitting element 220.

Please refer to FIG. 3 . It can be seen from the cross-sectional view that the reflective inner wall 243 is a pair of opposite curved segments, and the two curved segments are gradually extended away from the light exit opening 244. The expansion range of the two curved segments can be The light exit angle θ of the light-emitting element 220 is limited. The spread width of the reflective inner wall 243 is proportional to the light exit angle θ of the light-emitting element 220. As such, the reflective cup elements 240 having reflective inner walls 243 of different deployment amplitudes can control different light exit angles θ of the light-emitting elements 220, such as 15 degrees, 25 degrees, 45 degrees, or 60 degrees. However, it should be understood that the present creation is not limited thereto, and those having ordinary knowledge in the technical field of the present creation may flexibly select the kind of light angle depending on actual needs or limitations.

As shown in FIGS. 2 and 3, the track light fixture 100 further includes a light transmissive sheet 250. The transparent sheet 250, such as a light transmissive glass or a light transmissive plastic, directly covers the light exit opening 244 and is directly sandwiched between the cover 260 and the edge portion 245 to prevent dust from falling from the light exit opening 244 into the light body. Within 200.

As shown in FIG. 2 and FIG. 4, FIG. 4 is a perspective view of the outer cover 230 and the cover 260 of FIG. 2 at a relative viewing angle. The outer cover 230 includes a surrounding body 231, a cylindrical body 233 and a plurality of recessed holes 236. The cylindrical body 233 is located on the surrounding body 231 and has a common virtual axis line with the surrounding body 231. A. The cylindrical body 233 has a through passage 234 therein. The through-channel 234 is parallel to the opposite end faces of the cylindrical body 233 along the virtual axis line A, and is coaxial with the light-in port 246 and the light-emitting port 244. The so-called coaxial means that the three have a common virtual axis A. The cup body 241 of the reflective cup element 240 is received through the passage 234, and the light-emitting element 220 and the partial placement surface 211 are exposed from the end surface of the heat-dissipating base 210 from the cylindrical body 233. The surrounding body 231 surrounds the cylindrical body 233, and surrounds the cylindrical body 233 with the cylindrical body 233 surrounding the body 231, and an annular groove 235 is defined between the cylindrical body 233 and the cylindrical body 233. These recessed holes 236 are spaced apart from each other at the bottom of the annular groove 235. However, it should be understood that the recessed holes 236 are not limited to through holes or blind holes. Those skilled in the art can also select the recessed holes 236 as through holes or blind holes, depending on actual needs or limitations. Not limited to this.

The area of the outer peripheral surface of the surrounding body 231 is not uniform, especially as the position closer to the connecting rod 300, the smaller the area of the outer peripheral surface of the surrounding body 231, in other words, the surrounding body 231 has two opposite ends 231A, 231B. The two opposite ends 231A, 231B have a line 232 parallel to the virtual axis line A. The minimum linear length of the line 232 is smaller according to the closer to the connecting rod 300. In this way, the surrounding body 231 has a special shape to provide more choices for the user. However, it should be understood that the present invention is not limited thereto, and the person having ordinary knowledge in the technical field of the present invention may also be flexible according to actual needs or restrictions. The variation surrounds the shape, method and material of the body 231.

As shown in FIGS. 2 and 4, the cover 260 includes an annular body 261, an extension portion 264, and a plurality of protrusions 265. The annular body 261 has a uniform perforation 262 and an annular inner rim 263. The through hole 262 is coaxial with the light exit opening 244, and the annular inner edge 263 surrounds the through hole 262. When the transparent sheet body 250 and the reflective cup element 240 are placed in the lamp body 200, the transparent sheet body 250 is superposed on the light exit opening 244 and the edge portion 245. Thus, the light-transmissive sheet body 250 and the edge portion 245 which are stacked are sandwiched between the annular inner edge 263 and the cylindrical body 233 (Fig. 3). The extending portion 264 is located on the outer side of the annular body 261 away from the through hole 262 and protrudes in the same direction toward the heat dissipation base 210 to form a hollow cylinder with the annular body 261. Further, this stud 265 is spaced apart from the extension 264 on one side of the annular body 261.

Thus, when the cover 260 is placed on one end of the outer cover 230 opposite to the heat dissipation base 210, the extension portion 264 of the cover 260 is first inserted into the annular groove 235, and the protrusions 265 are respectively rotated by a suitable angle. When the recesses 236 are aligned, the projections 265 are inserted into the recesses 236 in the annular recesses 235, respectively, such that the extensions 264 are removably secured within the annular recesses 235.

In the embodiment, the heat dissipation base 210 further has a plurality of first screw holes 213, and the first screw holes 213 respectively penetrate the heat dissipation base 210, in order to make the cover 260 more securely fixed to the outer cover member 230. The opposite end faces; the recessed holes 236 at the bottom of the annular groove 235 are formed as through holes; and the second stud holes 266 are recessed in the protrusions 265 on the cover 260, respectively.

As shown in FIG. 2, when the lamp body 200 is assembled, when the cover 260, the outer cover 230 and the heat dissipation base 210 are integrally assembled in sequence, the first screw hole 213, the recess hole 236 and the second screw hole 266 are connected to each other. The cover 260 is coupled to the second screw hole 213, the recess 236, and the second screw hole 266 of the protrusion 265. The outer cover 230 can be more firmly locked on the heat dissipation base 210 without being disassembled from the heat dissipation base 210 by shaking the lamp body 200. At the same time, the reflector cup element 240 can also be more firmly sandwiched between the cover 260 and the outer cover 230, thereby ensuring stable optical performance.

In addition, in the present embodiment, the connecting rod 300 is substantially in the shape of a straight rod, the first end 310 is movably engaged with the lamp body 200, and the second end 320 is pivotally coupled to the sliding seat 400. As such, even if the sliding seat 400 is stationary, the lamp body 200 is movably movable relative to the connecting rod 300 or the sliding seat 400 to intentionally project light toward a particular area.

However, it should be understood that the present invention is not limited to the shape and material of the connecting rod 300, and the metal material selected is preferably high in stress strength. However, those skilled in the art to which the present invention pertains may also flexibly change the shape and material of the connecting rod 300 depending on actual needs or limitations.

In the embodiment of the present invention, the track luminaire 100 further includes a ball joint 500. The universal joint set 500 includes a receiving groove 510 and a screw member 520. The receiving groove 510 is opened at the first end 310 of the connecting rod 300. One end of the screw member 520 is locked to the heat dissipation base 210. The screw member 520 is further provided with a spherical head 521 at one end of the heat dissipation base 210. The spherical head 521 is movably disposed in the receiving groove 510. Thus, the bulb body 521 can be rotated in a multi-directional direction in the accommodating groove 510 by the accommodating groove 510, that is, the rotation of the ball, and the lamp body 200 can be rotated universally with respect to the screw member 520.

In addition, the screw member 520 has a rotation stop structure 522 with respect to one end of the spherical head 521. The rotation stop structure 522 makes the screw profile asymmetrical to limit the pivoting of the screw relative to the heat dissipation base 210. Specifically, the heat dissipation base 210 further has a positioning hole 214. The positioning hole 214 has a non-circular shape, and the hole shape matches the shape of the rotation preventing structure 522. Thus, when the rotation preventing structure 522 of the screw member 520 is extended into the positioning position. At the time of the hole 214, the rotation stop structure 522 is restricted by the positioning hole 214 and cannot be pivoted within the positioning hole 214, thereby confirming that the ball head 521 does not pivot together with the connecting rod 300.

The heat sink base is not limited to its appearance, manufacturing method and materials. For example, the heat sink base can be integrally formed by aluminum extrusion, and the selected metal material is preferably high heat dissipation performance. However, those skilled in the art to which the present invention pertains may also flexibly change the shape, method, and materials of the heat sink base depending on actual needs or limitations. Similarly, since the slip seat is already a conventional technique, it will not be described again here.

Thus, as can be seen from the above, with the design of the original track luminaire, since the reflector cup component can be easily and quickly disassembled from the track luminaire, the user can arbitrarily change the reflector cup components of different light angles according to requirements, so that the track lamp can provide different The type of illumination angle, in turn, meets the needs of users for different lighting purposes.

Although the present invention has been disclosed in a preferred embodiment as described above, any person skilled in the art can make various changes and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is attached. The scope defined in the scope of application for patent application shall prevail.
