Description

Technical Field

[0001] The technical field of the present application generally relates to lamps. In particular, the present disclosure relates to a method for replacing a light engine of a lamp. Background Art

[0002] In light of environmental challenges, such as the shortage of raw materials and resources, the compatibility of luminaires with the circular economy is becoming increasingly important. For example, in the case of upgrading or repairing a luminaire, the end user is encouraged to replace parts or components of the luminaire, such as the light engine, rather than the entire luminaire. Replacing the light engine of a luminaire may require tools and special technical knowledge that the end user does not possess. In addition, handling of the light engine by the end user may result in the light engine being damaged before it is installed in the luminaire. Summary of the invention

[0003] The purpose of this application is to provide a cost-effective possibility for replacing the light source of a luminaire and to reduce the risk of damage to the light engine.

[0004] According to a first aspect, a method for replacing a light source of a luminaire is provided. The method comprises providing a luminaire with a first light engine or at least one first light engine of the luminaire. The luminaire may in particular comprise a luminaire body or housing for receiving at least one light engine, in particular an LED (light emitting diode) light engine. The luminaire body may also be configured to receive other parts of the luminaire, such as an electrical driver or some driving components for driving at least one light engine.

[0005] The luminaire may further comprise a transparent or translucent cover for protecting or covering the light engine mounted in the luminaire. The luminaire may be substantially any kind of luminaire. In particular, the luminaire may be configured as a linear lamp, a sleeve lamp, a panel lamp, a low-bench luminaire, a moisture-proof luminaire or as a trunk system.

[0006] The method further comprises providing a light engine module or at least one light engine module having a second light engine, in particular for replacing the first light engine. The method further comprises removing the first light engine or at least one first light engine from the luminaire and installing the light engine module or at least one light engine module in the luminaire to replace the first light engine or at least one first light engine. The light engine module comprises a reinforcement or support for mechanically stabilizing the second light engine. The installation of the light engine module comprises installing both the second light engine and the reinforcement in the luminaire. The method may comprise opening a cover of the luminaire before removing the first light engine and / or closing the cover of the luminaire after the light engine module is installed in the luminaire.

[0007] Since the reinforcement of the light engine module provides mechanical stability to the second light engine, the risk of damage to the second light engine can be greatly reduced when the end user replaces the light engine module. In addition, since the first light engine can be installed during the manufacturing process of the luminaire instead of by the end user, it can be installed reliably and safely without reinforcement, so that the overall bill of materials (BOM) of the luminaire and the replacement light engine module can be reduced.

[0008] In some embodiments, the luminaire includes a mounting base or a mounting platform for mounting the light source, wherein removing the first light engine from the luminaire includes removing the first light engine from the mounting base, and installing the light engine module in the luminaire includes installing the second light engine and the reinforcement on the mounting base of the luminaire. The mounting base of the luminaire can provide support for securely mounting the first light engine and / or the light engine module.

[0009] In some embodiments, the light engine module is configured as a linear light engine module, which is substantially compatible with the first light engine or the bare light source. Substantially compatible in the present invention means that the light engine module is suitable as a substitute for the first light engine. In particular, the light engine module can have substantially the same form factor as the first light engine, so that it can be easily installed in the luminaire instead of the first light engine. The light engine module can further have substantially the same or enhanced light performance as the first light engine. The performance of light can be characterized in particular by luminous efficacy, color rendering, and any spectral or radiation characteristics of light. Due to the same or enhanced light performance, replacing the first light engine with a light engine module can at least maintain or even improve the light characteristics of the luminaire.

[0010] The first light engine and the second light engine may be configured as linear light engines. In particular, for an elongated linear light engine with a high aspect ratio, the risk of damage during handling increases. Therefore, the reinforcement measures provided in the light engine module can greatly reduce this risk.

[0011] The removal of the first light engine may include releasing at least one fixture or fixing means for fixing the first light engine in the luminaire, and the installation of the light engine module may include fixing the light engine module in the luminaire with at least one fixture. In particular, the luminaire may include one or more fixtures or fixing means for fixing the first light engine and / or the light engine module to a mounting base of the luminaire. By means of the fixture, the light engine may be reliably fixed in the luminaire.

[0012] According to a second aspect, a first light engine for installation in a lamp is provided. The first light engine comprises an LED substrate on which a plurality of LEDs are mounted. The LED substrate is configured to be replaceably or detachably mounted on a mounting base of the lamp. In the case of upgrading or repairing the lamp, the replaceably mounted light engine can be easily removed and / or replaced.

[0013] The LED substrate may have a substantially planar shape and may be configured to be replaceably mounted on a substantially planar mounting base of a lamp. Due to the planar shape of the LED substrate and the mounting base of the lamp, the mounting base may provide reliable support and good thermal connection for the LED substrate.

[0014] The first light engine may be configured as a linear light engine, in particular for installation in a linear and / or flat luminaire. The linear light engine is suitable as a light source for a linear luminaire as well as a panel luminaire, in particular when some linear light engines are arranged parallel to each other.

[0015] According to a third aspect, a light engine module for replacing a first light engine installed in a luminaire is provided. The light engine module includes a second light engine and a reinforcement for mechanically stabilizing the second light engine, wherein the reinforcement is configured such that the second light engine together with the reinforcement can be installed in the luminaire to replace the first light engine. Since the reinforcement of the light engine module provides mechanical stabilization of the second light engine, the risk of damage to the second light engine can be reduced when handling the light engine module during replacement.

[0016] The light engine module can be substantially compatible with the first light engine. Therefore, the light engine module can be easily installed in a lamp to replace the first light engine without requiring an additional process step of removing the second light engine from the reinforcement.

[0017] According to a fourth aspect, a luminaire is provided. The luminaire comprises a housing for receiving the first light engine according to the second aspect, wherein the housing is further configured to receive a light engine module according to the third aspect instead of the first light engine. The luminaire can be easily upgraded or repaired by replacing the first light engine with the light engine module. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 A perspective exploded view of a luminaire according to an embodiment is shown, the luminaire having a first light engine according to an embodiment. The luminaire 1 comprises a housing 2 and a mounting base 3 arranged in the housing 2 . Figure 1 Also shown is a first light engine 4 having an LED substrate 5 and some LEDs 6 mounted on the LED substrate 5 or a printed circuit board (PCB). The luminaire housing 2, the mounting base 3 and the LED substrate 5 each have an elongated shape. The LEDs 6 are arranged in a row between a first longitudinal end 7 and a second longitudinal end 8 of the LED substrate 5. The first light engine 4 is configured to be mounted on the mounting base 3 of the luminaire housing 2, so that after the first light engine 4 is mounted, the LEDs 6 are arranged along the elongated mounting base 3 of the luminaire 2. The luminaire 1 may also include electrical components, electrical drivers or some driving components for driving the light engine mounted on the mounting base 3. The housing 2 includes a mounting flange 9 mounted on the main body of the housing 2 by a mounting element 10. The mounting flange 9 is configured as a translucent cover for mounting the luminaire 1 to cover the mounting base 3 and the light engine mounted on the mounting base 3. For clarity, Figure 1 The translucent cover is not shown.

[0027] exist Figure 1In an embodiment, the luminaire 1 comprises a fixing element 11 for fixing the mounting base 3 in the luminaire housing 2. The fixing element 11 is configured as a snap-on connector so that the mounting base 3 can be easily fixed in the housing 2 of the luminaire 1. In the mounting base 3, an opening 12 is provided, which can be used for an electrical connection (not shown), for example, between a driver and a light engine 4. The opening 12 can also be configured as a fulcrum for adjusting the position of the mounting base 3 before fixing with the fixing element 11. The housing 2 also comprises ventilation holes 13 for air circulation, so as to cool the light engine 4 and / or the electronic devices of the driver during operation of the luminaire 1. At one longitudinal end of the luminaire housing 2, a cable hole 14 is provided for electrically connecting the luminaire 1 to an external power source.

[0028] In this embodiment, the luminaire 1 represents a so-called linear light. However, the present principles are not limited to such luminaires. In some embodiments, the luminaire can be configured as a panel light having one or more light engines. A panel light can in particular include several linear light engines arranged in parallel to provide a flat lighting surface. Figure 1 This corresponds to the lamp manufacturing mode, when the first light engine 4 is installed as the light source of the lamp 1 .

[0029] Figure 2 Shows Figure 1 A perspective exploded view of a luminaire with a light engine module 15 according to one embodiment. The light engine module 15 includes a second light engine 4 having an LED substrate 5 and a plurality of LEDs 6 arranged on the LED substrate 5. The LEDs 6′ are arranged in a row extending between a first longitudinal end 7′ and a second longitudinal end 8′ of the LED substrate 5′. The light engine module 15 also includes a reinforcement 16 for mechanically stabilizing the second light engine 4. The reinforcement 16 has an elongated shape and is configured to receive the second light engine 4′. Therefore, compared to the first light engine 4, the light engine module 15 with the second light engine 4′ also includes a reinforcement 16 or a bracket for mechanically stabilizing the second light engine 4′.

[0030] Due to the profile of the reinforcement 16, the reinforcement can provide the necessary support and stability for the second light engine. Thus, the risk of deformation or damage when handling the second engine 4' during the replacement process can be reduced. The reinforcement 16 or the support for the second engine 4 can be an aluminum profile, a plastic support or a metal plate, which can prevent deformation or damage to the engine.

[0031] exist Figure 2In an embodiment, the light engine module 15 is substantially compatible with the first light engine 4 or the bare light source. In particular, the light engine module can have substantially the same form factor as the first light engine, making it easier to install in the luminaire instead of the first light engine. The light engine module can further have substantially the same or enhanced light performance as the first light engine. In addition, in order to mount the light engine module 15 on the mounting base 3 of the luminaire 1, the same mounting techniques or mounting elements can be used. The performance of the light can be characterized in particular by the luminous efficacy, color rendering, and any spectral or radiation characteristics of the light. Due to the same or enhanced light performance, replacing the first light engine with the light engine module can substantially maintain or even improve the light characteristics of the luminaire. Figure 2 Corresponding to the light source replacement mode, the light engine module 15 with the second light engine 4 ′ and the reinforcement member 16 is installed as the light source of the lamp 1 .

[0032] Figure 3 1 shows a schematic cross-sectional view of a light source installation according to one embodiment. The light source 17 may be a first light engine 4, such as Figure 1 As shown, it can also be a light engine module 15, that is, a second light engine 4' together with a reinforcing member 16, such as Figure 2 As shown. In this embodiment, the mounting screws 18 are used as a fixing device for mounting the light source 17 on the mounting base 3 of the lamp. The light source 17 has openings or through holes for receiving the mounting screws 18, which can be screwed into corresponding threaded holes of the mounting base 3 of the lamp 1. In particular, the LED substrate 5 of the first light engine 4 can have through holes for receiving the mounting screws. Similarly, the LED substrate 5 of the second light engine 4 and the reinforcement 16 of the light engine module 15 can also have through holes for receiving the mounting screws. The size of the mounting screws 18 can be such that the mounting screws 18 can be used to install the first light engine 4, and can also be used to install the light engine module 15, that is, the second light engine 4′ together with the reinforcement 16. By means of the mounting screws, the first light engine 4 and / or the light engine module 15 can be reliably fixed to the mounting base 3 of the lamp.

[0033] Figure 4 A schematic cross section of a light source installation according to a second embodiment is shown. Figure 4 In the embodiment of the present invention, the mounting clip 19 is used to mount the light source 17 on the mounting base 3 of the luminaire 1. The size of the mounting clip 19 is such that the mounting clip 19 can be used to mount the first light engine 4, and can also be used to mount the light engine module 15, that is, the second light engine 4′ and the reinforcement 16. By means of the mounting clip 19, the first light engine 4 can be easily and quickly replaced by the light engine module 15.

[0034] Figure 5 A schematic cross section of a light source installation according to a third embodiment is shown. Figure 5In the embodiment of the present invention, the reinforcement 16 of the light engine module 15 serves as a support for the second light engine 4 ′. Therefore, the reinforcement has a dual function of mechanically stabilizing the second light engine 4 ′ and fixing the second light engine 4 ′ on the mounting base 3 of the luminaire 3 . Figures 3 to 5 The fixing structure shown can be used to fix the bare light source (without reinforcement) or the light engine module (light source together with reinforcement), even if the bare light source and the light engine module have different thicknesses.

[0035] In some embodiments, the reinforcement 16 has a substantially flat upper surface for receiving the substantially flat substrate of the light engine, and a substantially flat lower surface as a contact surface for mounting the reinforcement 16 on the mounting base 3. Due to the planar geometry, in particular the planar upper surface and the planar lower surface of the reinforcement 16, good thermal contact can be established between the second light engine 4' and the reinforcement 16, and between the reinforcement 16 and the mounting base 3.

[0036] Figure 6 A flow chart of a method for replacing a light engine in a luminaire according to an embodiment is shown. According to the method 50 for replacing a light engine in a luminaire, in a first step 100, a luminaire having at least one first light engine installed in the luminaire is provided. The first light engine can in particular be installed during the manufacturing process of the luminaire.

[0037] In step 200, at least one light engine module having at least one second light engine is provided to replace the first light engine. The at least one first light engine and / or the at least one second light engine may in particular include some light engines, such as linear light engines, in particular as described in the above embodiments. The light engine module may include at least one reinforcement or bracket for mechanically stabilizing the second light engine.

[0038] In step 300, the first light engine is removed from the luminaire, and in step 400, the light engine module is installed in the luminaire instead of the first light engine. In step 400, the installation of the light engine module includes installing the second light engine in the luminaire together with the reinforcement.

[0039] In some embodiments, the luminaire includes a mounting base for mounting the light source. Removing the first light engine in step 300 may include removing the first light engine from the mounting base of the luminaire. The installation of the light engine module in the luminaire may include installing a second light engine and a reinforcement on the mounting base of the luminaire.

[0040] The light engine module can be compatible with the first light engine. In particular, the light engine module can have substantially the same dimensions as the first light engine, so that it can be easily installed in a lamp, rather than using the same installation means to replace the first light engine.

[0041] In some embodiments, the luminaire includes a translucent cover for the light source. The method may include opening or removing the cover before removing the first light engine in step 300. The method may also include closing or installing the cover on the mounting flange of the luminaire after installing the light engine module in step 400.

[0042] In particular, since the reinforcement or fixing means are provided in the light engine module rather than in the first light engine, the light source can be replaced in a reliable and user-friendly manner. At the same time, the overall costs, including the costs of manufacturing the luminaire, can be kept at a low level.

[0043] Especially for luminaire products with slim linear light engines, such as moisture proof, wire trough systems, low window luminaires, panel or sleeve luminaires, the reinforcement measures provided in the light engine module help to greatly reduce the risk of damage to the light engine when replacing the light source of the luminaire. At the same time, the reinforcement device does not need to be part of the initial product, which may have a bare light engine, for example, just a PCB and LEDs mounted on it. Therefore, the manufacturing cost of the luminaire can be kept low.

[0044] Although at least one exemplary embodiment has been described in the foregoing detailed description, it should be understood that there are a large number of variations. It should also be understood that the exemplary embodiments or exemplary embodiments are only examples and are not intended to limit the scope, applicability or configuration of the present disclosure in any way. On the contrary, the above detailed description will provide a convenient roadmap for those skilled in the art to implement the exemplary embodiments or exemplary embodiments.
