Technical Field
[0001] The present invention relates to an interchangeable light-emitting unit and a lamp including the light-emitting unit. Background Technology
[0002] Our homes are equipped with numerous electronic devices, such as lighting fixtures. Defective electronics can cause damage, such as starting a fire or short circuit. Therefore, new home electronics need to be certified to meet specific standards before being introduced to the market. However, certifying home electronics is a costly and time-consuming process.
[0003] The purpose of this invention is to overcome these problems. Summary of the Invention
[0004] According to a first aspect of the invention, all or at least part of the above and other objects of the invention are achieved by an interchangeable light-emitting unit as defined in claim 1. According to that claim, the above objects are achieved by an interchangeable light-emitting unit comprising at least one of a light source, a battery, and a power port, processing circuitry configured to control the operation of the light source, and a connector configured to releasably connect the light-emitting unit / illumination unit to a lamp holder or lampshade of a luminaire.
[0005] This type of light-emitting unit is advantageous because it is modular and can therefore be used with different luminaires. Thus, the same interchangeable light-emitting unit can be reused with a variety of different luminaires without having to certify a new light-emitting unit for each luminaire. Therefore, the interchangeable light-emitting unit according to the invention reduces costs and saves time.
[0006] In the first embodiment, the interchangeable light-emitting unit is provided with an on / off switch.
[0007] According to a second embodiment, the interchangeable light-emitting unit includes a color-changing switch configured to change the color of light emitted by at least one light source. This provides a light-emitting unit that can help create different atmospheres in a room using the unit. It also provides a light-emitting unit with aesthetically pleasing lighting effects, and a light-emitting unit suitable for different purposes.
[0008] In one embodiment, the connector includes a first portion of a snap-fit mechanism or a first portion of a bayonet mounting structure, allowing the light-emitting unit to be connected to a lamp holder using the snap-fit mechanism or bayonet mounting structure. This provides a simple yet reliable connection between the light-emitting unit and the luminaire.
[0009] In one embodiment, the connector includes a receptacle forming a first portion of a snap-fit mechanism.
[0010] In another embodiment, the connector includes a flange extending along the outer periphery of the light-emitting unit. The flange is configured to connect to the lamp holder or lampshade by rotating relative to the lamp holder or lampshade such that the flange engages with a groove provided on the lamp holder or lampshade. This also provides a simple yet reliable connection from the light-emitting unit to the luminaire. Preferably, the flange extends laterally from the light-emitting unit.
[0011] In another embodiment, the connector includes a through-hole configured to receive a fastener such as a screw. This also provides a simple yet reliable connection from the light-emitting unit to the luminaire.
[0012] In one embodiment, the connector includes a flange, wherein the flange has a first portion for a snap-fit mechanism and / or at least one through-hole configured to receive a fastening device, such as a screw. This makes the light-emitting unit modular, allowing it to be connected to a lamp holder or lampshade in several different ways, and thus suitable for many different luminaire designs.
[0013] In another embodiment, the light-emitting unit has an upper portion and a lower portion, and at least one light source points upward from the light-emitting unit. The light-emitting unit includes an additional light source pointing downward from the light-emitting unit, thereby configuring the light-emitting unit to emit light upward and / or downward from the light-emitting unit.
[0014] This is advantageous because the light-emitting unit can emit light both upwards and downwards. Furthermore, a light-emitting unit with upward and downward-pointing light sources becomes easy to use with different types of luminaires that require the unit to emit light in different directions.
[0015] In another embodiment, at least one light source is arranged inside the light-emitting unit, and the upper and / or lower cover of the light-emitting unit comprises at least a translucent outer material, thereby configuring the light-emitting unit to emit light upwards and / or downwards. This is advantageous because the light-emitting unit can emit light both upwards and downwards. Furthermore, a light-emitting unit with upward and downward-pointing light sources is easy to use with different types of luminaires that require the light-emitting unit to emit light in different directions.
[0016] In one embodiment, the light-emitting unit includes a light direction switching switch configured to control the direction of light emitted from at least one light source, such that the light can point upwards, downwards, or both upwards and downwards. This is advantageous because it allows the user to select how light should be emitted from the luminaire including the light-emitting unit. Furthermore, the selected mode can be chosen according to the type of atmosphere the user wishes to create.
[0017] In another embodiment, the light-emitting unit includes a wireless receiver, and the light direction switching switch is configured to allow control of the direction of light emitted by the light source via an application, mobile phone, cloud server, or remote control through the wireless receiver. This is advantageous because the user can remotely control the light-emitting unit without physical contact with it. This is particularly advantageous when the light-emitting unit is located in a hard-to-reach luminaire.
[0018] In one embodiment, the light direction switching switch is a mechanical switch that can be manually operated to control the processing circuitry of the light-emitting unit, thereby allowing control of the direction of light emitted from at least one light source; or the light direction switching switch is a mechanical shield configured to shield or not shield at least one light source to allow control of the direction of light emitted from at least one light source; or the light direction switching switch is a manually operable guide configured to guide the at least one light source to allow control of the direction of light emitted from at least one light source. This allows the user to manually control the direction of light from the light-emitting unit.
[0019] In another embodiment, the light-emitting unit is in the shape of a disk, cylinder, sphere, cuboid, cube, or cylinder with a conical or curved conical top surface.
[0020] In one embodiment, the light-emitting unit has an upper part and a lower part, the lower part having a substantially flat external shape and the upper part having a non-flat external shape.
[0021] In another embodiment, the light-emitting unit includes at least one solar cell. The solar cell can be a solar panel. The advantage of a solar cell is that it can be used to provide energy to a light source. Alternatively, the solar cell can be used to charge a battery disposed within the light-emitting unit. Providing a solar cell in the light-emitting unit makes the unit sustainable and more environmentally friendly because it can be charged under sunlight and operate using solar energy in dark environments.
[0022] In one embodiment, the light-emitting unit includes at least a translucent material that allows light from at least one light source to be emitted and allows at least one solar cell disposed within the light-emitting unit to be exposed to and receive sunlight. This makes the light-emitting unit both aesthetically pleasing and still capable of charging the solar cell and emitting light from the light source disposed beneath the translucent material.
[0023] In a second aspect, a luminaire is provided comprising an interchangeable light-emitting unit, a lamp holder, and a lampshade as described herein. The lamp holder and / or lampshade are provided with a connection portion that can be releasably connected to a connector of the light-emitting unit. This is advantageous because the luminaire itself does not need to be certified as a household electronic product, since the light-emitting unit is already certified. Therefore, each lamp holder and / or lampshade only needs to be equipped with a connection portion to allow connection with the light-emitting unit. Thus, the manufacturing and certification costs of the luminaire can be reduced. Furthermore, new luminaire designs can be initiated and produced without having to spend time certifying each new design.
[0024] In one embodiment, the lamp holder comprises at least a translucent material such that when the light source of the light-emitting unit emits light into the lamp holder, the lamp holder emits light back out. Therefore, the lamp holder can also be used as a light source in the application environment without having an opening for emitting light.
[0025] In another embodiment, the lamp holder has a shape smaller than the lampshade, allowing it to be inserted into the lampshade during storage and / or transportation. Because the lamp holder is fitted into the lampshade, the space occupied by the disassembled lamp can be significantly reduced. Therefore, the required storage space can be reduced, and transportation costs can be lowered. Furthermore, the lamp holder is protected during storage and / or transportation.
[0026] In another embodiment, the lamp holder or lampshade has an opening with a shape corresponding to the shape of the light-emitting unit, allowing the light-emitting unit to be fitted into the opening. This is advantageous because the light-emitting unit can be tightly arranged in the lamp holder during use. This also ensures that the light-emitting unit has a fixed position within the lamp holder during use.
[0027] In another embodiment, the light-emitting unit has a color-changing switch configured to change the color of at least one light source. The color-changing switch is disposed on the light-emitting unit such that the lampshade blocks the color-changing switch when the light-emitting unit is releasably connected to the luminaire. This prevents unauthorized users from changing the color of the light. For example, in a restaurant, a guest unaware that the lampshade blocks the color-changing switch will not change the color of the light, while the restaurant operator can choose the color of light to be displayed.
[0028] In another embodiment, the lampshade is attached to the lamp holder using a bayonet mounting structure, wherein the lamp holder has a first portion of the bayonet mounting structure and the lampshade has a second portion of the bayonet mounting structure.
[0029] Other objects, features, and advantages of the invention will become apparent from the following detailed description, the appended claims, and the accompanying drawings. Note that the invention relates to all possible combinations of features.
[0030] Generally, unless otherwise expressly defined herein, all terms used in the claims shall be interpreted in accordance with their ordinary meaning in the relevant art.

[0047] The present invention relates to an interchangeable light-emitting unit 10. In short, the interchangeable light-emitting unit 10 includes at least one light source 11, a battery 12, processing circuitry configured to control the operation of the light source 11, and a connector 13 for connecting the light-emitting unit to a lamp holder or lampshade.
[0048] Reference Figures 1 to 4 Different luminaires 1 are shown, each including an interchangeable light-emitting unit 10. Each luminaire 1 includes a lamp holder 20 and a lampshade 30. The interchangeable light-emitting unit 10 is connected to the luminaire 1. Figures 1 to 4 As shown in the enlarged view of the light-emitting unit 10, each interchangeable light-emitting unit 10 includes at least one light source 11 and a connector 13 for connecting the light-emitting unit 10 to a lamp holder 20 or a lamp shade 30. The interchangeable light-emitting unit 10 has an upper part 2 and a lower part 3. Figures 1 to 4 The upper part 2 is shown in the middle. The lower part 3 is represented by a dashed line.
[0049] Figure 1 A freestanding desk lamp 1 is shown, with interchangeable light-emitting units 10 connected to the lamp base 20 of the desk lamp 1.
[0050] Figure 2A A chandelier 1 is shown. A replaceable light-emitting unit 10 is connected to the lamp holder 20 of the chandelier 1.
[0051] Figure 2B Another chandelier 1 is shown. A replaceable light-emitting unit 10 is connected to the lampshade 30 of the chandelier 1.
[0052] Figure 3 Floor lamp 1 is shown. Interchangeable light-emitting unit 10 is connected to lamp base 20 of floor lamp 1.
[0053] Figure 4 Wall lamp 1 is shown. Interchangeable light-emitting unit 10 is connected to lamp holder 20 of wall lamp 1.
[0054] Figure 5A side view of the interchangeable light-emitting unit 10 is shown, with the upper part 2 including a light source 11 and the lower part 3 including another light source 11'. In other embodiments, each upper part 2 and lower part 3 may be provided with an additional light source. Each light source 11, 11' is protected and covered by light source covers 11a, 11'a. Figure 5 The connector 13, in the form of a flange 16, is shown in the image. The flange 16 extends laterally from the light-emitting unit 10.
[0055] Go to Figure 6 The image shows a bottom view of the light-emitting unit 10. The lower part 3 has a lower cover 3a with a lower cap 5, which is removable and can be opened to expose the interior of the lower part 3, for example, when the battery 12 needs to be replaced. The lower part 3 also has another light source 11', which is covered by a light source cover 11'a. Details of the lower part 3 will be referenced below. Figure 8 To be further described.
[0056] also, Figure 6 The light-emitting unit 10 includes a connector 13. In this embodiment, the connector 13 includes a flange 16. The flange 16 extends circumferentially around the light-emitting unit 10. In other embodiments, the flange 16 may extend only partially around the outer periphery of the light-emitting unit 10.
[0057] Figure 6 The connector 13 in the embodiment also has a flange 16 with a through hole 17 and a first portion 13a of a snap-fit mechanism. The through hole 17 and the first portion 13a of the snap-fit mechanism are distributed along the flange 16. The through hole 17 and the first portion 13a of the snap-fit mechanism extend through the flange 16 in a vertical direction. The vertical direction is perpendicular to the transverse direction. Therefore, in this embodiment, the connector 13 includes a flange 16 with a through hole 17 and a first portion 13a of the snap-fit mechanism. In this way, the light-emitting unit 10 can be connected to the lamp holder 20 or the lampshade 30 in several different ways, making the interchangeable light-emitting unit 10 modular and adaptable. The connector 13 can also be the first portion of a bayonet mounting structure (not shown). (Refer to...) Figures 9A to 9C The different connectors 13 are explained in more detail in the form of flange 16, through hole 17 and first part 13a of snap-fit mechanism.
[0058] in addition, Figure 6 The interchangeable light-emitting unit 10 shown has an on / off selector 141, which in this embodiment is an on / off button 141. The on / off button 141 is disposed on a removable on / off switch cover 14. The interchangeable light-emitting unit 10 also has a power port 4. Figure 6In this configuration, the power port is a power USB-C port 4 protected by a removable USB-C port cover 4a, which is configured to shield the USB-C port 4. Therefore, the light-emitting unit 10 can be charged with a USB-C cable or used when the USB-C cable is connected to the power USB-C port 4. The light-emitting unit 10 may also have another type of port that can be connected to a charging cable, such as other types of USB ports (USB-A, USB-B, USB 3.0, micro-USB, or similar ports), or any other cable port suitable for powering the light-emitting unit 10.
[0059] Alternatively, the USB-C port cover 4a may be partially removed to expose the USB-C port 4; for example, the USB-C port cover 4a may be folded over the USB-C port 4.
[0060] Alternatively, the light-emitting unit 10 may include a wireless charging receiver, enabling the light-emitting unit 10 to be wirelessly charged via a unit containing a wireless charging transmitter.
[0061] Turn now Figure 7 An exploded view of the upper part 2 of the light-emitting unit 10 is shown. The upper part 2 has an upper cover 2a. The upper cover 2a is configured to be attached to the middle part 10a of the light-emitting unit. The upper part 2 is provided with a light source 11. The light source 11 faces the upper cover 2a of the light-emitting unit 10. The upper part 2 also includes a light source cover 11a. In addition, the upper part 2 is equipped with at least one solar cell 19. Figure 7 In this embodiment, the solar cell 19 is a solar panel. Therefore, the light-emitting unit 10 includes an upper part 2, a middle part 10a, and a lower part 3. Figure 1 In the embodiment of the light-emitting unit 10 shown in Figure 9, the connector 13 is disposed on the middle portion 10a.
[0062] Furthermore, the upper part 2 includes an optional light sensor 19a, preferably arranged inside the light-emitting unit 10, such as... Figure 7 As shown, the upper cover 2a comprises or is made of at least a translucent material, thereby allowing light to pass through the upper cover 2a and reach the light sensor 19a. The lower part 3 is also... Figure 7 As shown in the figure. The processing circuit of the light-emitting unit 10 can be configured to control the operation of the light source 11 based on data from the light sensor 19a. The processing circuit can be configured to control the operation of the light source 11 such that the light source 11 is turned on when the ambient light reaches a certain darkness threshold, and the light source 11 is turned off when the ambient light reaches a certain brightness threshold.
[0063] Figure 7The middle portion 10a of the light-emitting unit shown is provided with a joint portion 10b configured to hold and fix the solar cell 19. In this embodiment, the joint portion 10b is provided in the form of an elastic protrusion, so that a snap-fit connection can be formed between the solar cell 19 and the joint portion 10b.
[0064] Figure 8 The main focus is on an exploded view of the lower part 3 of the light-emitting unit 10. Figure 8 The upper cover 2a and the light source cover 11a are also shown. Similarly, as... Figure 7 As shown, the light-emitting unit 10 includes a middle portion 10a. The lower portion 3 includes a lower cover 3a. As described above, the connector 13 includes a flange 16 with a first portion 13a having a through hole 17 and a snap-fit mechanism. In addition, the light-emitting unit 10 is equipped with an on / off switch cover 14 and an on / off button 141.
[0065] Alternatively, the on / off switch cover 14 and the on / off button 141 are provided on the upper part 2 of the light-emitting unit 10, or both the upper part 2 and the lower part 3 are provided with the on / off button 141.
[0066] like Figure 8 As shown in the exploded view, in the assembled state, the on / off switch cover 14 covers the on / off switch 14a disposed below the on / off switch cover 14. When the user engages the on / off button 141, the on / off switch 14a is actuated. The on / off switch cover 14 is removable.
[0067] exist Figure 8 On the opposite side of the on / off switch 14a shown, the light-emitting unit 10 includes a power USB-C port 4, and the lower cover 3a includes a removable USB-C port cover 4a.
[0068] Adjacent to the on / off switch 14a, a second USB-C port 14C is provided, which is connected to the on / off switch 14a and provides a digital interface to the on / off switch 14a. Therefore, the on / off switch cover 14 can be removed, and optional independent adapters 14d, 14e can be connected to the second USB-C port 14c, which is connected to the on / off switch 14a and arranged adjacent to it.
[0069] The first adapter 14d is a smart home adapter, which includes a wireless receiver, enabling the light-emitting unit 10 to be controlled via the wireless receiver by a remote control, mobile phone, cloud server, or smart home application.
[0070] The second adapter 14e has a light sensor 14e' and an on / off selector 14e'' on two opposite sides of the second adapter 14e, both of which are located in Figure 8As shown in the diagram. The processing circuitry can be configured to control the operation of the light source 11 based on data from the light sensor 14e'. The processing circuitry can be configured to control the operation of the light source 11 such that the light source 11 is turned on when the ambient light reaches a dark threshold level, and turned off when the ambient light reaches a bright threshold level. Using the on / off selector 14e', the user can turn the light-emitting unit 10 on or off by actuating the selector 14e'.
[0071] Alternatively, the luminaire 1 has an extension on / off switch adapter 14' that can be connected to a second USB-C port 14c. The extension on / off switch adapter 14' has an on / off button 141', an extension cable 142', and a base plate 143'. The base plate 143' has a shape corresponding to the shape of the on / off switch cover 14, and the extension on / off switch adapter 14' has a USB-C connector (not shown) located below the base plate 143'. The length of the extension cable 142' can vary depending on the design of the luminaire 1. For example, if the luminaire 1 is as follows... Figure 2B In the chandelier 1 shown, the length of the extension cord 142' can be adapted to the height of the lampshade 30, so that the user can still easily access the on / off button 141' even when the extension on / off switch adapter 14' is covered by the lampshade 30. Alternatively, the extension on / off switch adapter 14' can be arranged such that the on / off button 141' is visible, but the extension cord 142' is covered by the lamp holder 20 or the lampshade 30.
[0072] In addition, the lower cover 3a includes a lower cover 5. In the assembled state, the lower cover 5 covers the battery 12, the additional light source 11', and the light direction switching switch 18. The light-emitting unit 10 also includes a light source cover 11'a, which covers the additional light source 11' in the assembled state.
[0073] The light direction switching switch 18 is configured to control the direction of light emitted from at least one light source 11 and another light source 11', such that light emitted from the light sources 11, 11' can be emitted upward, downward, or both upward and downward. Figure 8 In the illustrated embodiment, the light direction switching switch 18 is rotatable between different positions (not shown herein), wherein some positions control the processing circuitry, thereby controlling the operation of the light sources 11, 11', and one position allows the direction of light emitted from the light sources 11, 11' to be controlled by an application, mobile phone, cloud server, or remote control via a wireless receiver included in the light-emitting unit 10. The light direction switching switch 18 can also control the activation of the light sensor 19a. However, the light direction switching switch 18 can be any type of switch that allows the switch to control the processing circuitry of the light-emitting unit 10 and / or allows the light-emitting unit 10 to be remotely controlled, for example, by an application, mobile phone, cloud server, or remote control.
[0074] Alternatively, the light direction switching switch is a mechanical switching switch that can be manually operated to control the processing circuit of the light-emitting unit 10, thereby controlling the direction of light emitted from at least one light source 11 and / or another light source 11'.
[0075] In another embodiment, the light direction switching switch is a mechanical shielding element that can be manually moved to shield, partially shield, or not shield at least one light source 11 and / or another light source 11' to control the direction of light emitted from at least one light source 11 and / or another light source 11'.
[0076] In another embodiment, the light direction switching switch is a manually operable guide connected to at least one light source 11 and / or another light source 11' to allow control of the direction of light emitted from at least one light source 11 and / or another light source 11'.
[0077] Therefore, at least one light source points upward from the light-emitting unit 10, and another light source 11' points downward from the light-emitting unit 10 in the opposite direction. In this way, the light-emitting unit 10 can emit light upward and / or downward according to the mode used by the light direction switching switch 18. Preferably, in this case, the light sources 11, 11' are protected by light source covers 11a, 11'a.
[0078] Alternatively, at least one light source 11 and / or another light source 11' is arranged inside the light-emitting unit 10, and the upper cover 2a and / or lower cover 3a of the light-emitting unit 10 includes at least a translucent material, thereby allowing the light-emitting unit 10 to emit light upwards and / or downwards.
[0079] In one embodiment, the upper cover 2a and / or the lower cover 3a of the light-emitting unit 10 comprises at least a translucent material. This allows light to be emitted from at least one light source 11 and / or another light source 11', while also shielding components arranged inside the light-emitting unit 10. Furthermore, if the light-emitting unit 10 includes a solar cell 19, this allows the solar cell 19 arranged within the light-emitting unit 10 to be exposed to and receive sunlight. This also allows a light sensor 19a, which may be located internally, to operate.
[0080] In addition to the on / off switch 14a Figures 1 to 9C The light-emitting unit 10 shown may be equipped with a color-changing switch configured to change the color of the light emitted by at least one light source 11. This color can be changed by a processing circuit that controls the wavelength emitted by the light sources 11, 11'.
[0081] Now go to Figures 9A to 9CThe diagram illustrates the connection between different types of connectors 13 of the light-emitting unit 10 and the connection portion 21 of the lamp holder 20 or lampshade 30. The lamp holder 20 or lampshade 30 may be provided with one or more connection portions 21.
[0082] exist Figure 9A In the figure, connector 13 is provided in the form of a through hole 17. Fastening devices in the form of screws are indicated by dashed lines and are configured as shown to connect the light-emitting unit 10 to the lamp holder 20 or the lamp cover 30. Alternatively or additionally, the through hole 17 can be a threaded hole.
[0083] exist Figure 9B In this configuration, connector 13 is configured as a flange 16, which engages with a groove-shaped connecting portion 21 provided in the lamp holder 20 or lamp cover 30. The flange 16 is inserted into the groove and connected to the connecting portion 21 by the rotational movement of the flange 16 relative to the connecting portion 21.
[0084] exist Figure 9C In this configuration, connector 13 is configured as the first part 13a of a snap-fit mechanism. The first part 13a of the snap-fit mechanism is an opening sized to receive a connecting portion 21, which is a resilient hook-shaped protrusion. The resilient hook-shaped protrusion is pressed into and engages with the opening, and returns to its elasticity when the end of the protrusion is inserted into the opening 13a.
[0085] Alternatively, connector 13 may be configured as a rib or slat extending at least partially circumferentially, and connecting portion 21 may be configured as a receiving seat extending at least partially circumferentially, or conversely, the two may engage with each other, as shown in Figures 10 to 19. Figure 11 An embodiment of the light-emitting unit 10 shown is illustrated.
[0086] Figures 10A to 10C illustrate a light-emitting unit 10 according to another embodiment of the present invention.
