Description

Technical Field

[0001] The present invention relates to an electronic device, in particular to a lighting device. Background Art

[0002] Lighting devices are widely used in various living places, and the appearance, light angle and other features of each lighting device will also change according to different uses. For example, lighting devices used for reading can generally include table lamps, floor lamps and screen hanging lamps, among which screen hanging lamps are usually set on the upper edge of the screen to illuminate the screen and the desktop at the same time. Compared with traditional table lamps, screen hanging lamps can prevent light from directly shining on the screen and will not take up extra desktop space; in addition, when the user uses the screen hanging lamp in a writing posture, the light emitted by the screen hanging lamp is less likely to be blocked by the user's body. Therefore, screen hanging lamps are becoming more and more popular among consumers in the market.

[0003] However, most of the known screen hanging lamps have the disadvantages of being large in size, heavy in weight and complex in structure, which results in complicated assembly and poor yield of the known screen hanging lamps, and the subsequent maintenance cost is also difficult to reduce. In addition, the known screen hanging lamps can only irradiate light toward the desktop, and the usage scenario is relatively monotonous.

[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 lighting device with the advantages of simple structure and diverse usage scenarios.

[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, the lighting device provided by the present invention includes a housing, a first light-emitting element, a second light-emitting element, a substrate and a reflector. The housing has a first light-emitting portion and a second light-emitting portion separated from each other. The first light-emitting element is arranged in the housing and is used to emit a first light beam. The second light-emitting element is arranged in the housing and is used to emit a second light beam emitted from the second light-emitting portion. The substrate is arranged in the housing and electrically connects the first light-emitting element and the second light-emitting element. The reflector is arranged in the housing and is located on the transmission path of the first light beam. The reflector is used to reflect the first light beam to the first light-emitting portion.

[0008] The lighting device of the present invention uses a first light-emitting element and a second light-emitting element, and guides the first light beam and the second light beam to be emitted from the first light-emitting portion and the second light-emitting portion respectively through a reflector. Since the lighting device can emit the first light beam and the second light beam in different directions, the first light beam and / or the second light beam can be provided according to different usage scenarios, thereby providing a variety of lighting modes. In addition, the lighting device of the present invention uses a substrate to be electrically connected to the first light-emitting element and the second light-emitting element. Therefore, the lighting device omits at least one substrate, thereby having the advantages of small size, light weight and simple structure.

[0059] 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.

[0060] Figure 1 is a schematic diagram of a lighting device according to an embodiment of the present invention. Figure 2 yes Figure 1 Please refer to the schematic cross-sectional view of the lighting device. Figure 1 and Figure 2 The lighting device 100 includes a housing 110, a first light emitting element 120 (shown in FIG. Figure 1 ), a second light emitting element 130, a substrate 140 and a reflector 150. The housing 110 has a first light emitting portion 111 and a second light emitting portion 112 separated from each other. The first light emitting element 120 is disposed in the housing 110 and is used to emit a first light beam L1. The second light emitting element 130 is disposed in the housing 110 and is used to emit a second light beam L2 emitted from the second light emitting portion 112. The substrate 140 is disposed in the housing 110 and is electrically connected to the first light emitting element 120 and the second light emitting element 130. The reflector 150 is disposed in the housing 110 and is located on the transmission path of the first light beam L1. The reflector 150 is used to reflect the first light beam L1 to the first light emitting portion 111.

[0061] Figure 3 yes Figure 1 Schematic diagram of the use of lighting devices. Please continue to refer to Figure 1, the first light emitting portion 111 and the second light emitting portion 112 of the housing 110 can allow the light beam to pass through, while the portion other than the first light emitting portion 111 and the second light emitting portion 112 of the housing 110 has a light shielding effect. Further, the first light emitting portion 111 and the second light emitting portion 112 can be located on different sides of the housing 110, so that the first light beam L1 and the second light beam L2 can be emitted from the housing 110 in different directions. Please refer to Figure 1 and Figure 3 For example, the lighting device 100 of this embodiment can be arranged on a display device D (shown in Figure 3 ) to be used as a screen hanging lamp, so the first light emitting portion 111 can be oriented toward the desktop T to allow the first light beam L1 to pass through and illuminate the desktop T. On the other hand, the second light emitting portion 112 can be oriented toward the wall W to allow the second light beam L2 to pass through and illuminate the wall W. The first light emitting portion 111 and the second light emitting portion 112, for example, include a light-transmitting plate, and in one embodiment, the first light emitting portion 111 and the second light emitting portion 112 may have a haze to provide a uniform light effect. In the present embodiment, the shape of the shell 110 is, for example, cylindrical, but the present invention does not impose further restrictions on this. It can be understood that in other embodiments, the use of the lighting device 100 is not limited to screen hanging lamps, and the present invention does not impose further restrictions on the specific use of the lighting device 100.

[0062] In the present embodiment, the first light emitting element 120 and the second light emitting element 130 may include light emitting diodes, but the present invention is not limited thereto. In addition, the colors of the first light beam L1 and the second light beam L2 of the present embodiment may be different from each other. For example, the color of the first light beam L1 may include white to provide a lighting beam for reading toward the desktop T. On the other hand, the color of the second light beam L2 may include red, green and blue to provide a decorative contextual beam toward the wall W. However, the present invention does not impose any additional restrictions on the colors of the first light beam L1 and the second light beam L2.

[0063] Please refer to Figure 1 and Figure 2 , the substrate 140 of this embodiment includes, for example, a circuit board. Specifically, the substrate 140 may include a printed circuit board, and the first light emitting element 120 and the second light emitting element 130 may receive power via the aforementioned printed circuit board to generate the first light beam L1 and the second light beam L2 respectively. Incidentally, the power source of the lighting device 100 may include a battery or a socket, and the present invention does not limit this.

[0064] In the present embodiment, the reflector 150 may be in the shape of a plate. Specifically, the reflector 150, for example, includes a first plate 151 and a second plate 152. The first end E11 of the first plate 151 is disposed on the inner wall of the housing 110, and the first end E12 of the second plate 152 is disposed on the inner wall of the housing 110. The second end E21 of the first plate 151 is connected to the second end E22 of the second plate 152, wherein the first end E11 and the second end E21 are, for example, opposite to each other, and the first end E12 may be opposite to the second end E22. Specifically, the reflector 150 is disposed between the first light emitting portion 111 and the second light emitting portion 112, and the first plate 151 is located on the transmission path of the first light beam L1 and the second light beam L2 to reflect the first light beam L1 to the first light emitting portion 111, and reflect the second light beam L2 to the second light emitting portion 112. Specifically, the substrate 140 is disposed on a side of the second plate 152 facing the first plate 151, and the substrate 140 has a first surface S1 facing the first plate 151, and the first light emitting element 120 and the second light emitting element 130 are fixed to the first surface S1. Thus, the first light emitting element 120 can directly emit the first light beam L1 toward the first plate 151, and the second light emitting element 130 can directly emit the second light beam L2 toward the first plate 151. On the other hand, the first plate 151 reflects the first light beam L1 to the first light emitting portion 111, and reflects the second light beam L2 to the second light emitting portion 112.

[0065] In detail, the first plate 151 may have a reflective surface RS, a back surface BS, a light-transmitting portion 1511 and a reflective portion 1512. The reflective surface RS is opposite to the back surface BS and faces the first surface S1 and the first light exiting portion 111. The light-transmitting portion 1511 connects the reflective surface RS and the back surface BS. The reflective portion 1512 stands on the back surface BS and is adjacent to the light-transmitting portion 1511. The reflective surface RS is used to reflect the first light beam L1 to the first light exiting portion 111. The second light beam L2 is transmitted to the reflective portion 1512 via the light-transmitting portion 1511, and the reflective portion 1512 is used to reflect the second light beam L2 to the second light exiting portion 112. In short, the first light-emitting element 120 emits the first light beam L1 toward the reflective surface RS, and the reflective surface RS reflects the first light beam L1 to the first light exiting portion 111. In addition, the second light emitting element 130 emits a second light beam L2 toward the light-transmitting portion 1511, and the second light beam L2 enters the reflective portion 1512 after passing through the light-transmitting portion 1511, and is reflected by the reflective portion 1512 to the second light-emitting portion 112. In the present embodiment, the reflective surface RS is, for example, an inclined surface inclined relative to the first light-emitting portion 111. However, in other embodiments, the reflective surface RS may include a curved surface or a plurality of inclined surfaces connected to each other, and the present invention does not limit this.

[0066] In the present embodiment, the first surface S1 of the substrate 140 has a normal direction N1 pointing to the first plate body 151. The second light emitting element 130 is aligned with the light-transmitting portion 1511 in the normal direction N1, and the first light emitting element 120 is offset from the light-transmitting portion 1511 in the normal direction N1. In this way, the light-transmitting portion 1511 is not only located on the transmission path of the second light beam L2, but also offsets the transmission path of the first light beam L1, thereby ensuring that the second light beam L2 is emitted from the second light-emitting portion 112 and preventing the first light beam L1 from being emitted from the second light-emitting portion 112. In addition, because the first light beam L1 can be directly incident on the reflective surface RS after being emitted from the first light emitting element 120, the light utilization rate of the first light beam L1 can also be improved. Similarly, the second light beam L2 can be directly incident on the light-transmitting portion 1511 after being emitted from the second light emitting element 130, so the light utilization rate of the second light beam L2 can also be improved. The light-transmitting portion 1511 of the present embodiment includes, for example, a perforation, which can increase the brightness of the second light beam L2 incident on the reflective portion 1512, thereby further improving the light utilization rate of the second light beam L2. On the other hand, the first plate 151 and the reflective portion 1512 may be an integral structure. For example, the material of the first plate 151 and the reflective portion 1512 may include metal, and the perforation and the reflective portion 1512 may be formed on the first plate 151 through a stamping process. However, in one embodiment, the first plate 151 and the reflective portion 1512 may be a split structure, and the reflective portion 1512 may be fixed to the first plate 151 by bonding, screw locking, or mechanical engagement. It is understandable that the shape of the reflective portion 1512 is not limited to Figure 1 As shown, for example, the reflective portion 1512 may be a column or a cone standing on the back surface BS. Figure 1 There is no gap as shown, but the present invention is not limited to this. In other words, there may be a gap between the reflective portion 1512 and the light-transmissive portion 1511 to further adjust the path of the second light beam L2 reflected from the reflective portion 1512 to the second light output portion 112 .

[0067] Incidentally, in this embodiment, the first light emitting element 120 and the second light emitting element 130 are, for example, arranged on the substrate 140 along a straight line SL (drawn on Figure 1 For example, in one embodiment, the first light emitting element 120 and the second light emitting element 130 may be located on opposite sides of the straight line SL, and then arranged in an up-and-down staggered manner.

[0068] Compared with the prior art, the lighting device 100 of the present embodiment adopts a first light emitting element 120 and a second light emitting element 130, and guides the first light beam L1 and the second light beam L2 to be emitted from the first light emitting portion 111 and the second light emitting portion 112 respectively through the reflector 150. In this way, since the lighting device 100 can emit the first light beam L1 and the second light beam L2 in different directions, the first light beam L1 and / or the second light beam L2 can be provided according to different usage scenarios, thereby providing a variety of lighting modes. In addition, the lighting device 100 of the present embodiment adopts a substrate 140 electrically connected to the first light emitting element 120 and the second light emitting element 130. Therefore, the lighting device 100 omits at least one substrate, thereby having the advantages of small size, light weight and simple structure.

[0069] By the way, please refer to Figure 1 , the first plate 151 and the second plate 152 may be an integral structure, but other embodiments are not limited thereto. In this embodiment, the first end E11 of the first plate 151 and the first end E12 of the second plate 152 may be fixed to the housing 110 by gluing or screwing, but the present invention is not limited thereto. For example, please refer to Figure 4 In the lighting device 100a, the housing 110a, for example, has a plurality of snap-fit ​​mechanisms 111a, and the first end E11a of the first plate 151a and the first end E12a of the second plate 152a can be fixed in the snap-fit ​​mechanisms 111a. Specifically, the snap-fit ​​mechanism 111a is formed by extending from the inner wall of the housing 110a, and the snap-fit ​​mechanism 111a can include a groove, and the first end E11a of the first plate 151 and the first end E12a of the second plate 152 can respectively have bending portions B1 and B2 corresponding to the groove, so that the first plate 151a and the second plate 152a can be more firmly fixed in the groove via the aforementioned bending portions B1 and B2. It can be understood that although Figure 4 The shape of the reflector 150a is different from Figure 1 However, the present invention does not impose any restrictions on the shape of the reflector 150a.

[0070] Figure 5 is a schematic diagram of another embodiment of the lighting device of the present invention. The structure and advantages of the lighting device 100b of this embodiment are similar Figure 1 The following is an example of an embodiment of the present invention, and only the differences are described below. Please refer to Figure 5, the first plate 151b of the reflector 150b may have a reflective surface RSb, a back surface BSb and a light-transmitting portion 1511b. The reflective surface RSb is opposite to the back surface BSb, and the reflective surface RSb faces the first surface S1 and the first light-emitting portion 111. The light-transmitting portion 1511b connects the reflective surface RSb and the back surface BSb. The light-transmitting portion 1511b is located between the second light-emitting element 130 and the second light-emitting portion 112. In this embodiment, the second light-emitting element 130 adopts a side-emitting LED, and the light-transmitting portion 1511b is located on the transmission path of the second light beam L2. The reflective surface RSb is used to reflect the first light beam L1 to the first light-emitting portion 111. The second light beam L2 is transmitted to the second light-emitting portion 112 via the light-transmitting portion 1511b. In this way, the second light beam L2 is directly incident on the second light-emitting portion 112 after passing through the light-transmitting portion 1511b, thereby improving the light utilization rate of the second light beam L2. In detail, the second end E21b of the first plate 151b extends and is connected to the second end E22b of the second plate 152, and the first light emitting portion 111 and the second light emitting portion 112 may be located at opposite sides of the second end E21b. The light-transmitting portion 1511b may be located at the second end E21b and aligned with the second light-emitting element 130 to ensure that the second light beam L2 can be incident from the second light-emitting element 130 to the light-transmitting portion 1511b. Furthermore, the second light-emitting element 130 respectively has a side surface SS1 facing the second end E21b, the second light beam L2 is emitted from the side surface SS1 of the second light-emitting element 130, and the light-transmitting portion 1511b is aligned with the second light-emitting element 130 in the normal direction N2 of the side surface SS1. In the present embodiment, the light-transmitting portion 1511b may include a perforation, so that the light utilization rate of the second light beam L2 can be further improved, but other embodiments are not limited thereto.

[0071] Figure 6 is a schematic diagram of a lighting device according to another embodiment of the present invention. Figure 7 yes Figure 6 A schematic cross-sectional view of a lighting device. Figure 8 yes Figure 6 An enlarged schematic diagram of a first light-emitting element and a second light-emitting element. Fig. 9 yes Figure 6 The structure and advantages of the lighting device 100c of this embodiment are similar to Figure 5 The following is an example of an embodiment of the present invention, and only the differences are described below. Please refer to Figure 6 and Figure 7, the lighting device 100c, for example, further includes a first light shielding portion 160. The light-transmitting portion 1511c also extends between the first light-emitting element 120 and the second light-emitting portion 112 of the housing 110. The first light-emitting element 120 has a first top surface 121 and a first side surface 122, and the first top surface 121 faces away from the first surface S1 of the substrate 140 and faces the first plate body 151c. The first light beam L1 will only be emitted from the first top surface 121. The first side surface 122 is located between the first top surface 121 and the first surface S1, and faces the light-transmitting portion 1511c. The first light-shielding portion 160 covers the first side surface 122 to further avoid the possibility of the first light beam L1 emitted from the first top surface 121 being transmitted to the light-transmitting portion 1511c. In this embodiment, the light-transmitting portion 1511c, for example, includes a gap between the first plate body 151c and the second plate body 152, but the present invention does not impose many restrictions on the shape of the light-transmitting portion 1511c.

[0072] On the other hand, please refer to Figure 7 and Figure 8 , the first light emitting element 120 of the present embodiment further has a first side annular surface 123. The first side annular surface 123 is located between the first surface S1 and the first top surface 121 and is connected to the first side surface 122. In other words, the surface between the first top surface 121 of the first light emitting element 120 and the surface opposite to the first top surface 121 may be formed by the first side surface 122 and the first side annular surface 123. The first light shielding portion 160 may also cover the first side annular surface 123, so that the path of the first light beam L1 emitted from the first top surface 121 to be transmitted to the reflecting surface RSb of the first plate body 151c can be more consistent, and there will be no situation where the first light beam L1 emitted from the first top surface 121 is directly transmitted to the first light emitting portion 111 without passing through the reflecting surface RSb. The first side annular surface 123 of the present embodiment, for example, includes three surfaces S11, S21 and S31 of the first light emitting element 120, but the present invention is not limited thereto.

[0073] Please refer to Figure 6 , Figure 8 and Fig. 9 Similarly, the lighting device 100c further includes a second light shielding portion 170. The second light emitting element 130 has a second top surface 131 and a second side surface 132 (same Figure 5 The second top surface 131 faces away from the first surface S1 and faces the first plate 151c. The second light shielding portion 170 covers the second top surface 131. The second side surface 132 is located between the second top surface 131 and the first surface S1 and faces the light-transmitting portion 1511c. The second light beam L2 is emitted only from the second side surface 132. Figure 8 and Fig. 9, the second light-emitting element 130 also has a second side ring surface 133. The second side ring surface 133 is located between the first surface S1 and the second top surface 131 and is connected to the second side surface 132. In other words, the surface between the second top surface 131 of the second light-emitting element 130 and the surface opposite to the second top surface 131 can be composed of the second side surface 132 and the second side ring surface 133. The second light-shielding portion 170 can also cover the second side ring surface 133. The purpose of the second light-shielding portion 170 covering the second top surface 131 and the second side ring surface 133 is to avoid the possibility of the second light beam L2 being transmitted to the reflecting surface RSb of the first plate 151c. The second side ring surface 133 of this embodiment, for example, includes three surfaces S12, S22 and S32 of the second light-emitting element 130. In another embodiment, Figure 6 The first light shielding portion 160 and the second light shielding portion 170 may also be disposed at Figure 5 Lighting device 100b.

[0074] Fig.10 is a schematic diagram of another embodiment of the lighting device of the present invention. The structure and advantages of the lighting device 100d of this embodiment are similar Figure 1 The following is an example of an embodiment of the present invention, and only the differences are described below. Please refer to Fig.10 , the substrate 140 is disposed on a side of the second plate 152d facing the first plate 151d. The substrate 140 has a first surface S1 and a second surface S2 facing each other. The first surface S1 faces the first plate 151d of the reflector 150d, and the second surface S2 faces the second plate 152d. The first light-emitting element 120 is fixed to the first surface S1. The second light-emitting element 130 is fixed to the second surface S2 and accommodated in the through hole H of the second plate 152d. In detail, the substrate 140 includes, for example, a double-sided printed circuit board, and the first light-emitting element 120 and the second light-emitting element 130 can be respectively fixed to the first surface S1 and the second surface S2 through a double-sided reflow process (Surface Mount Technology, SMT). In addition, the second surface S2 can be fixed to the second plate 152d and face the second light-emitting portion 112 of the housing 110d through the through hole H, and the second light-emitting element 130 can be exposed from the second plate 152d through the through hole H. Furthermore, the reflective surface RSd of the first plate 151d faces the first surface S1 and the first light emitting portion 111, and the reflective surface RSd is used to reflect the first light beam L1 to the first light emitting portion 111. The second light beam L2 is transmitted to the second light emitting portion 112 via the through hole H. Therefore, the second light beam L2 emitted by the second light emitting element 130 can be directly incident on the second light emitting portion 112, thereby improving the light utilization rate of the second light beam L2.

[0075] In summary, the lighting device of the present invention uses a first light-emitting element and a second light-emitting element, and guides the first light beam and the second light beam to be emitted from the first light-emitting portion and the second light-emitting portion respectively through a reflector. Since the lighting device can emit the first light beam and the second light beam in different directions, it can provide the first light beam and / or the second light beam according to different usage scenarios, thereby providing a variety of lighting modes. In addition, the lighting device of the present invention uses a substrate to be electrically connected to the first light-emitting element and the second light-emitting element. Therefore, the lighting device omits at least one substrate, thereby having the advantages of small size, light weight and simple structure.
