Description

Technical Field

[0001] The invention relates to the field of lighting, and in particular to a lighting device installed on a screen. Background Art

[0002] In order to get comfortable lighting when reading, desk lamps are the most common source of desktop lighting. However, as computers become more and more popular, in addition to desk lamps, readers also need to place computer-related equipment such as screens, keyboards, mice, etc. on their desks, making the space on the desktop even smaller.

[0003] In the face of the above situation, there is currently a type of lamp that is set on the screen, which saves desktop space by using the screen as a bracket for the lamp. In order to avoid using traditional light bulbs to block the screen or change the center of gravity of the screen due to excessive weight, this type of lamp mostly uses smaller and lighter light-emitting elements as light sources, which has a higher degree of freedom in design.

[0004] This "Background Technology" section is only used to help understand the content of the present invention. Therefore, the content disclosed in the "Background Technology" may contain some known technologies that are not known to those skilled in the art. In addition, the content disclosed in the "Background Technology" does not represent the problems to be solved by the content or one or more embodiments of the present invention, nor does it mean that it has been known or recognized by those skilled in the art before the application of the present invention. Summary of the invention

[0005] The present invention provides a screen lighting device, which can provide two kinds of lighting lights irradiated in different directions, and can change the lighting style of one of the lighting lights according to needs.

[0006] Other purposes and advantages of the present invention can be further understood from the technical features disclosed in the present invention.

[0007] To achieve one or part or all of the above purposes or other purposes, one embodiment of the present invention provides a screen lighting device, including: a body, a first light source and a second light source. The body includes a first shell and a second shell. The second shell can be detachably connected to the first shell. The first light source is connected to the body and is used to generate a first light beam. The second light source is connected to the body and is used to generate a second light beam. The first shell is used for the first light beam to be emitted along a first direction, and the second shell is used for the second light beam to be emitted along a second direction, which is different from the first direction.

[0008] From the above description, it can be seen that in addition to providing a first light beam toward a first direction through a first shell, the present invention also generates a second light beam emitting toward a second direction through a second shell that can be detachably assembled and separated from the first shell. Therefore, the screen lighting device of the present invention can provide two types of lighting lights toward different directions, and the lighting style of the second light beam can be changed according to needs.

[0064] The above-mentioned other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only the directions with reference to the accompanying drawings. Therefore, the directional terms used are used to illustrate and not to limit the present invention.

[0065] Figure 1 It is a schematic diagram of the assembly of a screen lighting device according to an embodiment of the present invention. Figure 2A for Figure 1 A front view schematic diagram of the screen lighting device after the first shell and the second shell are combined in the embodiment. Figure 2B for Figure 2A A schematic cross-sectional view of the assembled screen lighting device in the embodiment.

[0066] like Figures 1 to 2B As shown, the screen lighting device 1 of the embodiment of the present invention comprises: a body 2, a first light source 3 and a second light source 4. The body 2 comprises a first shell 21 (see Figure 2A ) and the second housing 22 (see Figure 2A The second housing 22 is detachably connected to the first housing 21. The first light source 3 (see Figure 2B ) is connected to the body 2 and is used to generate a first light beam L1. The second light source 4 is connected to the body 2 and is used to generate a second light beam L2. The first shell 21 is used for the first light beam L1 to be emitted along a first direction D1, and the second shell 22 is used for the second light beam L2 to be emitted along a second direction D2, which is different from the first direction D1.

[0067] Specifically, if Figure 1As shown, the body 2 is, for example, in a strip shape. When installed, the body 2 is mounted on the upper edge of a screen (not shown) through a bracket (not shown), and the long axis direction E1 of the body 2 is, for example, parallel to the upper edge of the screen. The body 2 can, for example, rotate relative to the bracket with the long axis direction E1 of the body 2 as the axis, so that the first direction D1 and the second direction D2 defined by the first shell 21 and the second shell 22 rotate relative to the screen.

[0068] like Figure 2A and Figure 2B As shown, in this embodiment, the first shell 21 includes, for example, a shell 21A, a receiving groove 212, and a first receiving chamber S1. Specifically, in this embodiment, the shell 21A forms a first receiving chamber S1 and two receiving grooves 212, and the first receiving chamber S1 and these receiving grooves 212 are respectively located on opposite sides of the shell 21A, and the receiving grooves 212 are respectively arranged along the long axis direction E2 of the shell 21A. The shell 21A, for example, has a first opening 212c, and the first opening 212c opens toward the first direction D1 and communicates with the first receiving chamber S1. The receiving groove 212 is, for example, a rectangular groove body that is concave toward the first receiving chamber S1 along the second direction D2 of the shell 21A, and has a bottom surface 212a. The receiving groove 212 is used to accommodate the second shell 22 when the first shell 21 and the second shell 22 are combined, and is, for example, connected to the second shell 22 through a plug hole 212b opened on the bottom surface 212a.

[0069] The shape of the accommodating groove 212 is not limited to the above-mentioned examples. In other embodiments not shown in the figure, the accommodating groove 212 formed on the shell 21A can, for example, be composed of an opening connected to the first accommodating cavity S1, and the second shell 22 can be configured as a shell for being clamped on the periphery of the accommodating groove 212 (opening). In other words, the relative positions of the first accommodating cavity S1 and the accommodating groove 212 can be changed, and the shape of the accommodating groove 212 is not limited to the above-mentioned examples.

[0070] like Figure 2A and Figure 2B As shown, in this embodiment, the body 2 further includes a light-transmitting plate 211. The shape of the light-transmitting plate 211 corresponds to the opening shape of the receiving groove 212, and is used to cover the receiving groove 212 and face the second direction D2 after the second housing 22 is disposed in the receiving groove 212.

[0071] The first light source 3 is located in the first accommodating cavity S1. The first light source 3 is, for example, a light bar, and the light bar has, for example, a plurality of light-emitting diodes (LEDs). These LEDs are, for example, arranged in the first accommodating cavity S1 along the long axis direction E1 of the body 2. The first light beam L1 generated by these LEDs is, for example, used as illumination light, and its color is, for example, white, but the color and the type of the first light source 3 are not limited thereto.

[0072] like Figure 2A and Figure 2B As shown, the screen lighting device 1 in this embodiment may also include a circuit board 213 (see Figure 2B ), reflector 214 and diffuser 215. The circuit board 213 is located in the first accommodating chamber S1, and obtains external power through, for example, a connector 2131 penetrating the center of the first shell 21, and cooperates with a button 216 and a dial (not shown, electrically connected to the circuit board 213) installed on the first shell 21 to control the operation of the first light source 3, for example but not limited to controlling the luminous intensity or color temperature. The reflector 214 is located in the first accommodating chamber S1 and is located in front of the light path of the first light source 3. The diffuser 215 is, for example, arranged to cover the entire first opening 212c. However, the specific types or shape designs of the above components related to the first shell 21 are not limited to the above examples.

[0073] like Figure 2A and Figure 2B As shown, in this embodiment, the body 2 has two second shells 22. Each second shell 22 has a second accommodating cavity S2 (see Figure 2B ). Since the detailed structures of the two second shells 22 are the same, the design of only one of the second shells 22 will be described below. Specifically, the second shell 22 includes, for example, a support plate 221 and a cover plate 222. The support plate 221 is, for example, a U-shaped plate extending along the long axis direction E1 of the body 2, and has a second opening 221a opened toward the second direction D2. The cover plate 222 covers the second opening 221a and forms the second shell 22 together with the support plate 221.

[0074] In the present embodiment, the second light source 4 is located in the second accommodating cavity S2, and the second light beam L2 is emitted toward the second opening 221a through the cover plate 222. The second light source 4 is, for example, a light emitting module that can change the color of the second light beam L2, and for example, has a plurality of light emitting diodes (not shown) for generating light beams of different colors, such as red, blue and green light emitting diodes, and can generate a plurality of second light beams L2 of different colors by mixing colors through different light intensities between each other. In other words, in the present embodiment, the color of the second light beam L2 generated by the second light source 4 can be changed according to a control circuit not shown in the figure, but the detailed types and functions of the second light source 4 are not limited to the above.

[0075] In terms of the electrical connection, the support plate 221 includes a connection portion 221b on a side away from the second accommodation cavity S2. One end of the connection portion 221b is electrically connected to the second light source 4, and the other end protrudes from the surface of the support plate 221, and is used to pass through the jack 212b on the housing 21A and extend into the first housing 21 to be electrically connected to the circuit board 213. With this structure, the user can control the light-emitting mode of the second light source 4 through a button (not shown) or a knob (not shown) provided on the first housing 21, but is not limited thereto.

[0076] In this embodiment, the second light source 4 and the cover plate 222 are arranged along the second direction D2. The cover plate 222 is, for example, a diffuser. The cover plate 222 has a light incident surface 222a and a light emitting surface 222b. The light incident surface 222a faces the second light source 4. The second light beam L2 passes through the cover plate 222 and emits toward the second opening 221a, but is not limited thereto. In another embodiment, the cover plate 222 is, for example, a light guide plate. The second light source 4 emits the second light beam L2 along the long axis direction E1 of the body 2. At this time, the second light source 4 and the cover plate 222 are arranged along the long axis direction E1 of the body 2. The cover plate 222 has a light incident surface and a light emitting surface (not shown). The light incident surface faces the second light source 4, and the light emitting surface determines the direction of the second direction D2. The specific types or shape designs of the components related to the second shell 22 are not limited to the above examples. Please refer to the following description for details. It should be understood that since the number of second shells 22 and second light sources 4 corresponds to the number of accommodating grooves 212 , in other embodiments not shown in the figure, the screen lighting device 1 may also have only one second shell 22 and one second light source 4 .

[0077] Figure 3A It is a schematic assembly diagram of a screen lighting device according to another embodiment of the present invention. Figure 3B The construction of the second shell is similar to Figure 3A Schematic cross-sectional view of a screen lighting device of an embodiment of an embodiment. In the screen lighting device 1' of this embodiment, the structure of the first shell 21' can be substantially the same as that of the previous embodiment, so only the differences are described here. In addition, since the structures of the two second shells 22' in this embodiment are the same, the structure of only one of the second shells 22' is described below.

[0078] like Figure 3A As shown, in this embodiment, different from the above Figure 2AIn the embodiment, the first housing 21' includes two combination parts 217 in addition to the first accommodation cavity S1, and does not have the aforementioned accommodation groove 212. The two combination parts 217 are used to assemble the second housing 22. The shape of the combination part 217 is, for example but not limited to, similar to the accommodation groove 212 in the aforementioned embodiment, and the two combination parts 217 are, for example, arranged along the long axis direction E1 of the first housing 21', but the detailed shape of the combination part 217 is not limited thereto, for example, Figure 3B In the figure, the combination portion 217 may be an opening (not numbered because it is covered by the second shell 22).

[0079] like Figure 3A As shown, in the present embodiment, the first shell 21' has an axis A along the long axis direction, and the extension direction of the axis A is different from the first direction D1 and the second direction D2, for example, it is parallel to the long axis direction E1 of the body 2'. The second light source 4' is disposed in the first shell 21' and is located outside the first accommodating cavity S1. The number of the second light source 4' can be, for example, one and is disposed between the two combination parts 217, and has an opening 41 facing the combination parts 217 on both sides. In other words, the two combination parts 217 are located outside the first accommodating cavity S1 and on a side of the second light source 4' on different sides along the axis A. When activated, the second light beam L2 generated by the second light source 4' directly or through the opening 41 emits the second light beam L2 toward the two combination parts 217 along different directions on the axis A, but is not limited thereto. In another embodiment, there may be multiple second light sources, which are arranged in the first shell 21' and located outside the first accommodating cavity S1, and are respectively arranged corresponding to the two combination parts 217. That is, when activated, the second light beam L2 generated by each second light source 4' is directly or through the opening 41 along the axis A to emit the second light beam L2 toward the corresponding combination part 217.

[0080] In this embodiment, the second housing 22' includes, for example, a housing 22A, a light-transmitting plate 222' and a light-guiding plate 223. The housing 22A surrounds a slot body 201 similar to the aforementioned receiving slot 212. The light-transmitting plate 222' covers the opening of the slot body 201 and forms a second receiving cavity S2 together with the slot body 201. The second receiving cavity S2, i.e., one side of the slot body 201, has a light-transmitting light-entering portion 202 (see FIG. 2 ). Figure 3A ), the light entrance portion 202 is, for example, a light-transmissive portion of the housing 22, or a hole. When assembled, the light guide plate 223 is fixed in the second accommodation cavity S2, and the light entrance surface 223a of the light guide plate 223 faces the light entrance portion 202. When the second housing 22 is assembled to the assembly portion 217, the light entrance portion 202 faces the second light source 4, and the second light beam L2 of the second light source 4 is used to enter the second housing 22 through the light entrance portion 202.

[0081] Through the above structure, when the first housing 21' and the two second housings 22' are assembled, the light incident portion 202 is located on the axis A. When the second light source 4' generates the second light beam L2, the second light beam L2 is emitted along the axis A toward the light incident portion 202 on the second housing 22', and is emitted to the light incident surface 223a of the light guide plate 223, and is emitted toward the second direction D2 from the light emitting surface 223b of the light guide plate 223.

[0082] In this embodiment, the screen lighting device 1' further includes a pattern generating element 5. The pattern generating element 5 is connected to the second housing 22' and is disposed on the transmission path of the second light beam L2. The pattern generating element 5 is used to convert the second light beam L2 into a pattern light beam L3. Specifically, the pattern generating element 5 in this embodiment is, for example, a light shielding pattern disposed on the light-transmitting plate 222'. When the second light beam L2 passes through the light-transmitting plate 222', a portion of the second light beam L2 will be shielded by the pattern generating element 5 to generate a pattern light beam L3 corresponding to the shape of the light shielding pattern.

[0083] In other embodiments not shown in the figures, the pattern generating element 5 may include a filter pattern having a plurality of different color portions. When the second light beam L2 passes through the light-transmitting plate 222', the portion of the second light beam L2 that passes through the filter pattern will become a pattern beam having different colors. In addition, in one embodiment, the light-transmitting plate 222' itself may also be used as the pattern generating element 5. Specifically, a portion of the light-transmitting plate 222' may be formed with a plurality of lenses, and a pattern is generated by deflecting a portion of the second light beam L2, so that the pattern presents diversity. In other similar embodiments, Figure 3A In the embodiment of the embodiment, the pattern generating element 5 can also be disposed on the light emitting surface 223b of the light guide plate 223, such as a microstructure on the light guide plate 223, so that the emitted light presents a desired pattern through the distribution of the microstructure, or in other similar Figure 2A In the embodiment of the embodiment, the pattern generating element 5 can also be disposed on the light emitting surface 222b of the cover plate 222, such as a microstructure on the cover plate 222. It should be understood that in different embodiments, the configuration or form of the pattern generating element 5 is not limited to the above examples.

[0084] Figure 4 FIG. 1 is a cross-sectional schematic diagram of the installation position of the second housing in another embodiment of the present invention. In this embodiment, the first housing (not shown) can be connected to the aforementioned Figure 3A The designs of the embodiments are the same, but the detailed design of the second housing 22 ″ may be changed, and only the changed parts will be described below.

[0085] like Figure 4As shown, in this embodiment, the light emitting surface 223b of the light guide plate 223 is, for example, covered with a diffuser 215', and the contact surface of the light guide plate 223 and the second shell 22" is, for example, provided with a reflective layer 7. The light-transmitting plate 222' has, for example, a plurality of light-transmitting holes 222c. In similar embodiments, the light-transmitting holes 222c can be arranged in a pattern and used as a pattern generating element 5, but is not limited thereto.

[0086] It can be seen from the above examples that the detailed structure of the second shell of each embodiment of the present invention can be changed according to the position of the second light source, and the user can change the detailed structure of the second shell according to the needs of setting or generating patterned light beams.

[0087] Figure 5 This is a cross-sectional schematic diagram of a screen lighting device after the first shell and the second shell are combined in another embodiment of the present invention. Figure 5 As shown, in this embodiment, the screen lighting device 1" also includes a bracket portion 6, and the first shell 21" and the second shell 22" (for convenience, the detailed structure is not drawn) are connected through the bracket portion 6. Figure 5 As shown, specifically, the bracket portion 6 is, for example, composed of a plurality of latches 61, and the first shell 21″ and the second shell 22″ may be provided with holes 62 corresponding to the latches 61, but the present invention is not limited thereto. It should be understood that the shape of the bracket portion 6 may be changed as required. And in some embodiments, the connection position or angle between the bracket portion 6 and the second shell 22″ may be changed. In other words, the connection position or direction between the bracket portion 6 and the second shell 22″ may be changed, or even the design of the bracket portion 6 may be changed so that it has a rotating shaft (not shown) so as to be able to change the direction of the second direction D2 toward which the second shell 22″ is facing.

[0088] From the above description, it can be seen that in addition to providing a first light beam toward a first direction through a first shell, the present invention also generates a second light beam emitting toward a second direction through a second shell that can be detachably assembled and separated from the first shell. Therefore, the screen lighting device of the present invention can provide two types of lighting lights toward different directions, and the lighting style of the second light beam can be changed according to needs.

[0089] However, what is described above is only the preferred embodiment of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. That is, all simple equivalent changes and modifications made according to the claims and the content of the invention of the present invention are still within the scope of the patent of the present invention. In addition, any embodiment or claim of the present invention is not required to achieve all the purposes, advantages or features disclosed by the present invention. In addition, the abstract and title (invention name) are only used to assist in the retrieval of patent documents, and are not used to limit the scope of rights of the present invention.
