DETAILED DESCRIPTION
(13) The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which currently preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and fully convey the scope of the invention to the skilled person.
(14) FIGS. 1a-b illustrate a power track 10 according to an embodiment of the present invention. The power track 10 may be used for mounting and powering at least one electronic product 12, such as a lighting product (e.g. a spotlight), as shown in FIG. 1c. The power track 10 and the at least one electronic product 12 mountable or mounted to the power track 10 may be referred to as a system 100. The power track 10 will typically be used to mount and power 2-20, preferably 3-10, electronic products 12. That is, the system 100 will typically comprise 2-20, preferably 3-10, electronic products 12.
(15) The power track 10 comprises a mounting surface 14. The mounting surface 14 may be a top mounting surface, as in FIGS. 1a-c. The mounting surface 14 of the power track 10 may be flat or at least comprise one or more flat portions, so that the power track 10 can be stably mounted on an installation surface 18. The mounting surface 14 may comprise means 16 for surface-mounting the power track 10 on the installation surface 18. Various exemplary means 16 are shown in FIGS. 5a-f and will be discussed further hereinbelow. The power track 10 further comprises a linear opening 20. The linear opening 20 preferably extends along (substantially) the complete length L of the power track 10. The power track 10 may for example have a length L in the range of 1-10 meters. The linear opening 20 is adapted to receive a connector 22 of the electronic product 12 to be mounted to the power track 10. That is, the connector 22 mechanically and electrically connects the electronic product 12 to (the linear opening 20 of) the power track 10.
(16) The linear opening 20 is facing in a direction 24 parallel to the mounting surface 14 (and parallel to the installation surface 18). Accordingly, the linear opening 20 could be referred to as a sideways-oriented opening 20. In FIG. 1c, the power track 10 is mounted to a ceiling (=installation surface 18), and the linear opening 20 is facing to the left. In FIG. 1d, the power track 10 is mounted to a wall (=installation surface 18), and the linear opening 20 is facing upwards. In both instances, the linear opening may become less visible for a user at typical user positions relative to the power track 10.
(17) In FIGS. 1a-e, the power track 10 has a single linear opening 20. The single linear opening 20 may be formed by a U-shaped cross-section of the power track 10. This cross-section of the power track 10 may comprise the aforementioned mounting surface 14, a planar linear front 26 opposite and parallel to the mounting surface 14, and a single planar linear element 28 projecting from one end of the mounting surface 14 to a corresponding end of the planar linear front 26.
(18) The power track further comprises at least one linear light source 30. The at least one linear light source 30 may extend along (substantially) the complete length L of the power track 10. The linear light source 30 may be a linear array of LED (light emitting diode) nodes 32 or LED filaments. Each LED node 32 may be a combination of LEDs, such as RGB or RGBWW, to enable each node to render a specific color. An LED node 32 could also consist of a single LED. The linear light source 30 may offer general illumination, which may be combined with accent spotlights 12.
(19) As shown for example in FIGS. 1a-e, the at least one linear light source 30 may be arranged within the linear opening 20. Specifically, the at least one linear light source 30 may be located at a backside 34 of the aforementioned planar linear front 26 of the power track 10. This integrated at least one linear light source 30 may be adapted to illuminate the installation surface 18. The inside of the linear opening 20 may be reflective (and diffusive). However, the planar linear element 28 of the power track 10 could be translucent (FIG. 1e). This enables the linear light source 30 to provide illumination of the installation surface 18 at both sides of the power track 10, as illustrated by arrows 36. Translucent may be construed as permitting the passage of light, for example transparent.
(20) The power track 10 may comprise two (power track) electrodes 38a-b for powering the electronic product(s) 12 mounted to the power track 10. The electrodes 38a-b could also power the at least one integrated linear light source 30. The power tracks 38a-b may be arranged within the linear opening 20. In FIGS. 1a-d, the electrodes 38a-b are located at the backside 34 of the planar linear front 26, to hide them from the user's view. Specifically, the electrodes 38a-b are here located in between three linear light sources 30. Alternatively, one electrode 38a could be located at the backside 34 of the planar linear front 26, whereas the other electrode 38b is located at the opposite side 40 of the opening 20, as shown in FIG. 1e.
(21) In FIGS. 1a-e, the connector 22 of the electronic product 12 may be at least partly translucent, to minimize it influence on the light output (e.g. 36) of the at least one linear light source 30, even if the electronic product 12 is positioned in front of the linear light source 30. In particular, at least one part or portion of the connector 22 used for mechanically connecting the electronic product 12 to the power track 10 could be made for example of transparent plastics.
(22) In a variant shown in FIG. 2a, the at least one linear light source 30 and the electrodes 38a-b are (again) arranged within the linear opening 20 behind the planar linear front 26, but the electrodes 38a-b are recessed compared to the at least one linear light source 30. Furthermore, the electrodes 38a-b are positioned further from a bottom 42 of the linear opening 20 than the at least one linear light source 30, which bottom 42 is defined by the aforementioned planar linear element 28. Also, the connector 22 is or comprises a clamp clamping partly around the planar linear front 26 including the recessed electrodes 38a-b (but not the at least one linear light source 30 placed further in), such that at least one linear light source 30 is positioned above the connector 22. In this way, the connector 22 hardly influences the light output 36 of the linear light source 30.
(23) In another variant shown in FIG. 2b, the at least one linear light source 30 and the electrodes 38a-b are (again) arranged within the linear opening 20 behind the planar linear front 26, but the clamp of the connector 22 has a comb structure, wherein LED nodes 32 of the linear light source 30 sit between teeth 44 of the comb structure adapted to abut the back surface 34 when the electronic product 12 is mounted to the power track 10. In this way, the connector 22 hardly influences the light output 36 of the linear light source 30.
(24) FIGS. 3a-b illustrate a power track 10 according to another embodiment of the present invention. The power track 10 in FIGS. 3a-b may be similar to the previous described power track, but has double or dual (i.e. two) linear openings. Namely, the power track 10 in FIGS. 3a-b comprises a first linear opening 20 facing in a first direction 24 parallel to the mounting surface 14, and a corresponding second linear opening 20 facing in a second direction 24 parallel to the mounting surface 14, which second direction 24 is opposite the first direction 24. The first and second linear openings 20, 20 may be formed by an H-shaped cross-section of the power track 10. This cross-section of the power track 10 may include the aforementioned mounting surface 14, the planar linear front 26 opposite and parallel to the mounting surface 14, and a single central planar linear element 28 projecting from the mounting surface 14 to the planar linear front 26. The H-shaped power track 10 may enable strong mechanical support for heavy lamps 12, for example a pendant lamp as shown in FIG. 3b. The connector 22 may here be adapted to be attached to the H-shaped power track 10 by retracting or rotating (part of) the connector 22.
(25) The H-shaped power track 10 may comprise two or more linear light sources: at least one first linear light source 30 arranged within the first linear opening 20, and at least one second linear light source 30 arranged within the second linear opening 20. The linear light sources 30 and 30 may be located at the backside 34 of the common planar linear front 26. The linear light sources 30 and 30 enable illumination of the installation surface 18 on both sides of the power track 10, as illustrated by 36 and 36, optionally creating two distinct light effects. The second linear opening 20 may also comprise (power track) electrodes 40a and 40b.
(26) FIGS. 4a-b illustrate other embodiments of the present invention.
(27) In FIG. 4a, the power track 10 comprises a linear light source 46 be provided on, or integrated in, an outer side of the power track 10. The linear light source 46 may be provided instead of, or in addition to, the aforementioned linear light source 30, 30. Specifically, the linear light source 46 is in FIG. 4a provided at a frontside 48 of the planar linear front 26 of the power track 10. In this way, the external linear light source 46 can face downwards if the power track 10 is mounted in a ceiling 18.
(28) In FIG. 4b, the planar linear front 26 of the power track 10 comprises a lateral extension 50 on one or both sides of the power track 10. A linear light source 52 may be provided on/behind the lateral extension 50, rather than in the linear opening 20. Accordingly, the linear light source(s) 52 may face the installation surface 18. That is, the linear light source 46 can face upwards if the power track 10 is mounted in a ceiling 18. The lateral extension 50 may also hide part of the electronic product 12, see FIG. 4b (right).
(29) FIGS. 5a-f illustrate different means 16 for surface-mounting the power track 10 on the installation surface 18.
(30) In FIG. 5a, means 16 comprises an adhesive strip 54 on the mounting surface 14. The adhesive strip 54 could extend along (substantially) the complete length of the power track 10, or consist of several adhesive sub-strips distributed along the length of the power track 10. The adhesive strip 54 is in particular suitable for light-weight track and electronic products.
(31) In FIG. 5b, means 16 comprises a linear mounting strip 56 provided on the mounting surface 14. The linear mounting strip 56 is adapted to slide over the head 58 of one or more mounting screws 60 inserted into the installation surface 18. The linear mounting strip 56 may have on opening 62 through with the head 58 can pass, and a narrower channel 64 locking the power track 10 to the mounting screws 60 when the power track 10 subsequently is moved in the longitudinal direction.
(32) In FIG. 5c, said means comprises linear edges 66a-b on both sides of the mounting surface 14, for sliding or clicking or clamping the power track 10 into separate clips 68 mounted to the installation surface 18.
(33) In FIG. 5d, said means comprises at least one screw hole 70 from the mounting surface 14 to surface 40. Also, at least one (wider) screwdriver hole 72 is provided through the planar linear front 26, which at least one screwdriver hole 72 is aligned with the least one screw hole 70. At least one plug 74 may be provided to seal the at least one screwdriver hole 72 after mounting of the power track 10 on the installation surface 18.
(34) In FIGS. 5e-f, the at least one screw hole 70 and the at least one screwdriver hole 72 are provided in the planar linear element 28.
(35) The person skilled in the art realizes that the present invention by no means is limited to the preferred embodiments described above. On the contrary, many modifications and variations are possible within the scope of the appended claims. For example, instead of or in addition to one or more lighting products, at least one other electronic product could be mounted to and powered by the present power track, for example a sensor, a loudspeaker, a display, a projection device, etc.
(36) Additionally, variations to the disclosed embodiments can be understood and effected by the skilled person in practicing the claimed invention, from a study of the drawings, the disclosure, and the appended claims. In the claims, the word comprising does not exclude other elements or steps, and the indefinite article a or an does not exclude a plurality. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measured cannot be used to advantage.
