Description

Technical Field

[0001] The technical field of the present application generally relates to light sources. In particular, the present disclosure relates to light sources for installation in luminaires and luminaires having light sources. Background Art

[0002] In view of environmental challenges such as raw material and resource shortages, the compatibility of luminaires with the circular economy has become increasingly important. For example, in the case of luminaire upgrades or repairs, end users and / or installers are encouraged to replace parts or components of the luminaire rather than the entire luminaire. However, replacing certain parts of a luminaire may require tools and specialized technical knowledge that end users may not have. In the case of luminaires having LED (light emitting diode) light sources, replacing the light source without damaging the LED light source or the optical engine can be a challenging task. Summary of the Invention

[0003] The object of the present application is to provide a particularly simple and reliable way to replace the light source in a luminaire.

[0004] According to a first aspect, there is provided a light source for installation in a luminaire. The light source includes at least one mounting base for placement on at least one mounting platform of the luminaire. In particular, the at least one mounting base may include a substantially flat contact surface for contacting a substantially flat contact surface of at least one mounting platform of the luminaire.

[0005] The at least one mounting base is configured such that by sliding the mounting base of the light source on at least one mounting platform of the luminaire, the at least one mounting base can be brought into a position where at least one fixing element of the luminaire and at least one mounting base of the light source at least partially overlap. In particular, the sliding or movement of the at least one mounting base can be performed in a lateral direction (i.e., parallel to the contact plane of the at least one mounting base and the at least one mounting platform). Thereby, the light source is fixed to the luminaire by at least one fixing element of the luminaire. In particular, due to the overlap of at least one fixing element and at least one mounting base of the light source, the at least one mounting base can be at least partially covered by at least one fixing element of the luminaire, thereby preventing the light source from separating from the luminaire. To remove the light source from the luminaire, the light source can be moved back to a position where the mounting base is not covered by at least one fixing element, such that the mounting base of the light source can be easily separated from the mounting platform of the luminaire.

[0006] Thus, the light source can be easily installed in the luminaire in two steps (i.e., placing and moving the mounting base). Thus, the light source can be easily removed from the luminaire in the same two steps in the reverse order, i.e., by moving and removing the mounting base from the mounting platform of the luminaire.

[0007] The mounting base may include at least one channel or through-hole for at least one fixing element of the luminaire, such that at least one mounting base can be placed on at least one platform of the luminaire. In particular, at least one channel of the at least one mounting base may be configured such that when the at least one mounting base is placed on the mounting platform of the luminaire, at least one fixing element of the luminaire does not block the path of the mounting base.

[0008] The light source may be configured as a linear light source, wherein the at least one mounting base is configured to fix the light source by means of a plurality of fixing elements distributed along at least one long side of the light source. In particular, the plurality of fixing elements may be arranged in at least one row along at least one long side of the light source. Especially in the case of a long light source (such as a linear light source), the plurality of fixing elements arranged along at least one long side of the light source can ensure that the light source is reliably fixed in the luminaire along its entire length.

[0009] The at least one mounting base may include at least one recess on at least one long side of the at least one mounting base. In particular, the at least one recess may be configured to receive at least one fixing element of the luminaire, such that the at least one mounting base can be easily placed on at least one mounting platform of the luminaire.

[0010] The light source may include at least one printed circuit board, wherein the at least one mounting base is formed by the at least one printed circuit board of the light source. Thus, at least one printed circuit board (PCB) of the light source or the light engine can be used both for mounting the electrical components of the light source and for mounting the light source in the luminaire without any additional mounting means.

[0011] In some embodiments, the light source includes a holding element, especially for stabilizing the shape of the light source, wherein the at least one mounting base is formed by the at least one holding element. Thus, the holding element can combine the functions of a stabilizing element and a mounting element, such that the light source is particularly stable and easy to install.

[0012] In particular, the holding element may be configured as a holding profile for holding the printed circuit board of the light source. Especially in the case of a linear light source having an elongated printed circuit board, the holding profile can provide reliable support for stabilizing the shape of the printed circuit board.

[0013] According to a second aspect, there is provided a luminaire having at least one light source according to the first aspect. The luminaire includes at least one fixing element for fixing the light source and at least one mounting platform for placing the mounting base of the light source, such that by sliding at least one mounting base on the light source on at least one mounting platform of the luminaire, the at least one mounting base can be brought into a position where at least one fixing element of the luminaire and at least one mounting base of the light source at least partially overlap, so that the light source is fixed to the luminaire by at least one fixing element of the luminaire. Through the above two-step installation or removal process, the light source can be easily and reliably installed in the luminaire or easily and reliably replaced in the luminaire.

[0014] The luminaire may be configured to receive a linear light source, wherein at least one fixing element includes a plurality of fixing elements for fixing the light source along at least one long side of the light source. Due to the plurality of fixing elements distributed along the long side of the light source, the light source fixed reliably in the luminaire along the entire length of the light source is fixed securely.

[0015] The luminaire may include a stopper for restricting the sliding path of at least one mounting base of the light source. By means of the stopper or limiter, the mounting base can be automatically stopped at the correct position during the installation of the light source. Description of the Drawings

[0031] Figure 1 showing a partial perspective view of the luminaire according to an embodiment. In particular, Figure 1 showing the mounting member 1 of the housing of the luminaire, which is configured to accommodate the light source.

[0032] In the illustrated embodiment, the luminaire is configured as a linear lamp having an elongated luminaire body. For greater clarity, in Figure 1 only a part of the mounting member 1 of the housing is shown.

[0033] The mounting member 1 includes a substantially contoured elongated body, which is configured to accommodate an elongated light source or a linear light source. In particular, the mounting member 1 includes a mounting platform 2 for mounting the mounting base of the light source. The mounting member 1 further includes a fixing element 3 for fixing the mounting base of the light source to the mounting platform 2 of the mounting member 1 of the luminaire housing.

[0034] Figure 2Shows a partial perspective view of a light source according to an embodiment. In this embodiment, the light source 4 is configured as an LED light source having a plurality of LEDs 5 mounted on a printed circuit board (PCB) 6. The light source 4 further includes a connector 7 mounted on the PCB 6 for electrically contacting the PCB 6 to a power source.

[0035] The PCB 6 has an elongated, substantially rectangular shape with a first long side 8 and a second long side 9 opposite the first long side 8.

[0036] The PCB 6 includes a plurality of recesses 10 and a plurality of mounting areas 11 disposed on the first long side 8 and the second long side 9 of the PCB 6. In this embodiment, the mounting areas 11 are configured as contact pads of the PCB 6. In some embodiments, the surface of the mounting area is the same as the surface of the remainder of the PCB 6 that has no electrical contacts or contact pads.

[0037] Figure 3 Shows a partial perspective view of a luminaire having a light source according to Figure 2 an embodiment in a first position. The luminaire 12 includes a housing 13 in which a mounting member 1 according to Figure 1 is disposed. In this embodiment, the luminaire 12 is configured as a linear lamp for mounting on a ceiling. In Figure 3 the position shown, the light source is disposed on the mounting platform 2 in a first position or a pre-fixed position. In this position of the light source 4 relative to the luminaire housing 13, the fixing element 3 of the mounting member 1 is located in the recess 10, and the mounting area 11 is not covered by the fixing element 3. Thus, since the fixing element 3 does not hold the light source 4, the light source 4 is released.

[0038] Figure 4 Shows Figure 3 a partial perspective view of a luminaire having a light source in a second position. In the second position or the fixed position, the light source 4 is positioned such that the fixing element 3 of the mounting member 1 is located on the mounting area 11 of the PCB 6.

[0039] Compared with Figure 3 the first or pre-fixed position shown, the light source 4 has been moved to the left relative to the luminaire housing 13 such that the fixing element 3 can press on the mounting area 11 and can hold the PCB 6 of the light source 4 in this position. Thus, the PCB 6 serves as a mounting base for the light source 4, which is mounted on the mounting platform 2 of the luminaire 12 and fixed by the fixing element 3.

[0040] Figure 5 Shows a top view of a luminaire according to Figure 3 and Figure 4 in two different positions of the light source. In Figure 5In [the figure], the luminaire 12 is shown over its entire length. In the present embodiment, the luminaire 12 includes five fixing elements 3 on each of the long sides 8 and 9 of the light source 4. The light source 4 includes five recesses 10 and five mounting areas 11 on each of the long sides 8 and 9 of the PCB 6.

[0041] In the upper part of the figure, the light source 4 is shown in the second or fixed position, where the fixing element 3 is located on top of the mounting area 11. In the lower part of the figure, the light source 4 is shown in the first or pre-fixed position. In this position, the fixing element 3 is located in the longitudinal position of the recess 10. Thus, the PCB 6 or the mounting base of the light source 4 is not covered by the fixing element 3. Thus, in the pre-fixed position, which can also be referred to as the post-fixed position, the PCB 6 or the mounting base of the light source 4 is not fixed to the mounting platform 2 of the luminaire 12. Thus, from the pre-fixed position or the post-fixed position, the light source 4 can be freely removed from the mounting platform, for example for replacement, or fixed by simply moving it slightly in the longitudinal direction. The moving distance of the light source 4 for fixing and / or removing the light source can be as short as a few millimeters or a few centimeters, making the installation and replacement of the light source 4 particularly convenient for the user or installer.

[0042] Figure 6 A partial perspective view of a light source according to a second embodiment is shown. Similar to Figure 3 the embodiment of Figure 6 the embodiment includes a plurality of LEDs 5 arranged in rows on an elongate PCB 6 that is substantially rectangular. Figure 6 The light source 4 of Figure 2 also includes a plurality of recesses 10 and mounting areas 11. However, compared to

[0043] Figure 7 the embodiment of Figure 6 the recesses 10 are provided only on one long side 8 of the PCB 6, while the mounting areas 11 are provided on both long sides 8 and 9 of the PCB 6. Figure 2 A mounting process of a light source according to

[0044] Figure 7 the embodiment of Figure 5 is shown. Similar to the mounting process of the light source 4 of

[0045] Figure 2 the light source 4 is first placed on the mounting platform 2 of the luminaire together with the mounting base or the PCB 6, and then moved to the fixed position, where the fixing element 3 is located on top of the mounting pads of the PCB 6, thereby fixing the light source 4 in the luminaire.

[0044] Figure 7 The light source 4 on the mounting member 1 of the luminaire is shown in three different positions. In the first position or pre-fixed position (left side in the figure), the light source 4 is located on the mounting platform 2, similar to the pre-fixed position discussed above in connection with Figure 5

[0045] In the second or semi-fixed position, the light source moves laterally (upward in the figure) such that the mounting base or PCB 6 is partially covered by the fixing element 3 on one side.

[0046] In the third or fixed position, similar to Figure 5 the fixed position in the embodiment of, the PCB 6 is fixed by the fixing element 3 on both long sides 8 and 9 of the PCB 6 or on the mounting base.

[0047] Therefore, in Figure 7 the embodiment of, the light source 4 can be installed in a three-step process, including placing the mounting base or PCB 6 on the mounting platform 2 of the luminaire, moving the mounting base laterally so that one long side of the mounting base engages with the fixing element 3, and moving the mounting base in the longitudinal direction such that both long sides of the mounting base engage with or are fixed by the fixing element 3. Compared with Figure 2 the embodiment of, this embodiment of the light source 4 includes a smaller number of recesses 10 in the PCB 6. Therefore, the light source 4 is not only easy to install but also more stable.

[0048] Figure 8 shows a detailed perspective view of the light source and the luminaire according to a further embodiment. In Figure 8 the embodiment of, the light source 4 includes a PCB 6 having LEDs 5 and connectors 7 and a holding element 14, with the LEDs 5 and connectors 7 mounted on the PCB 6, similar to Figure 2 the embodiment of. In this embodiment, the holding element 14 is an aluminum profile configured to accommodate the PCB 6 and mount the light source 4 on the mounting platform 2 of the luminaire. In particular, an aluminum profile can be optionally added to retrofit the light source 4, for example as a spare part light source.

[0049] For greater clarity, Figure 8 the lower right part of shows an enlarged schematic cross-section of the holding element 14. The holding element 14 includes a bottom part 15 for mounting the light source 4 in the luminaire and a top part 15' for accommodating the PCB 6 of the optical engine. In particular, the bottom part 15 of the holding element 14 includes recesses 10, similar to Figure 2 or Figure 6 the recesses 10 of the PCB 6 in the embodiment of. Therefore, the bottom part 15 of the mounting element 14 can be used as a mounting base for mounting the light source 4 in the luminaire such that the bottom part 15 is held by the fixing element 3 of the luminaire. This embodiment of the light source 4 can be easily installed in the luminaire in a two-step installation process, similar to Figure 2Embodiments. Due to the retaining element 14, the light source 4 is particularly stable because the retaining element 14 stabilizes the shape of the PCB 6, as the flexibility of the PCB may make the replacement process difficult. The aluminum profile can be configured such that the light source 4 with the aluminum profile as the retaining element 14 still has a certain flexibility to enable easy replacement, but is rigid enough for easier handling.

[0050] Figure 9 A perspective view of a luminaire with a light source according to another embodiment is shown. Figure 9 The luminaire 12 of Figure 5 The embodiment is substantially corresponding to Figure 2 and Figure 6 except that some recesses 14 or cutouts are missing in the PCB 6 of the light source 4. In some embodiments, there are no cutouts at the position of the last or the last two fixing elements 3. Thus, in these embodiments, the light source 4 cannot be installed in the same way as the light source 4 in the embodiments according to Figure 10 and

[0051] Figure 11 A first partial view of a luminaire with a light source according to an embodiment is shown. In this embodiment of the luminaire, the luminaire includes a stop 16 for longitudinal positioning of the PCB 6.

[0052] Figure 12 Shown according to Figure 11 A second partial view of the luminaire. In particular, Figure 12 Shown Figure 11Partial cross-section in a perspective view of an embodiment. In the cross-sectional view, the shape of the spring clip can be seen. The spring clip 16 is formed as an elastic band, including a first end fixed to the mounting member 2 by a fixing element (in particular a rivet 17 or a screw) and a second end configured to receive the longitudinal end of the PCB 6. Due to the stopper 16, the PCB 6 or the light source 4 can be mechanically stabilized in its fixed position.

[0053] Figure 13 A partial view of a luminaire according to an embodiment is shown. In Figure 13 the embodiment, the luminaire includes a PCB fixing pin 18 for additionally stabilizing the PCB 6. An enlarged view of the fixing pin 18 is shown on the right side of the figure. The PCB fixing pin 18 has barbs 19 for connecting the fixing pin 18 to the PCB 6, thereby preventing the fixing pin 18 from falling off before or during the installation process.

[0054] As shown in the above description of the embodiments of the light source and the luminaire, the light source can be easily installed and / or replaced without the need to move the light source over a longer travel distance. In particular, compared with the longitudinal dimension of the light source, bringing the light source in a partially fixed, pre-fixed, semi-fixed position into the fixed position does not require a large range of movement of the light source, and vice versa. In addition, due to the bilateral fixing of the fixing element and due to the optional stopper, reliable fixing of the light source in the luminaire can be achieved. In some embodiments, the mounting pad is configured as a ground contact for electrically connecting the PCB or the light source via the fixing element of the conductive mounting member of the luminaire, thereby improving safety.

[0055] For linear lamps with long light sources or PCBs, the above system allows the light source to be installed particularly easily and firmly in a luminaire mounted on the ceiling, especially because of the short travel path of the light source for bringing the light source into different fixed positions. In addition, the above-described embodiments of the light source are characterized by a simple structure and a low BOM (Bill of Materials). For installing and fixing the light source, no additional fixing elements or tools are required, which may be easily lost during the installation or replacement of the light source.

[0056] Due to the short travel distance for inserting or removing the light source, less space is required for installing or replacing the light source. In addition, since the overall positive effect is achieved by making minor modifications to the light source, the light source can still comply with relevant standards, such as the standards of the Zhaga Consortium.

[0057] Although at least one exemplary embodiment is given in the above detailed description, it should be understood that there are numerous variations. It should also be understood that one or more exemplary embodiments are merely examples and are not intended to limit the scope, applicability, or configuration of the present disclosure in any way. Instead, the above detailed description will provide those skilled in the art with a convenient roadmap for implementing one or more exemplary embodiments.
