Description

Technical Field

[0001] This application belongs to the technical field of lighting devices, and particularly relates to a lighting device. Background Art

[0002] Currently, most of the lamps on the market adopt a direct lighting method, that is, the light source of the lamp emits light and directly emits light downward for lighting. Although the lamps adopting the direct lighting method can improve the brightness of the illumination, the glare value of the illumination light is relatively large, and the illumination light causes great harm to the human eye, and it is not suitable for home lighting or lighting in long-term office places.

[0003] In related technologies, there are also some lamps that adopt an indirect lighting method, that is, after the light source of the lamp emits light, the light propagates upward, and after being reflected, the light emits light downward for lighting. Although the lamps adopting the indirect lighting method can make the illumination light relatively soft, light loss will occur when the light is reflected, resulting in a decrease in the brightness of the illumination light, making it impossible to meet the brightness requirements of users for the illumination light.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] As Figure 1 and Figure 5 shown, the lighting device provided by the embodiment of this application includes a lamp shade 10, a light source mounting part 20, a first light source 30, a second light source 40, and an optical component 50. The lamp shade 10 is provided with a light outlet 11, and the inner wall surface of the lamp shade 10 is set as a reflecting surface 12. The light source mounting part 20 is arranged inside the lamp shade 10, and there is a spaced arrangement between the light source mounting part 20 and the inner wall of the lamp shade 10. The first light source 30 is mounted on one side of the light source mounting part 20 facing the inner wall of the lamp shade 10. Since there is a spaced arrangement between the light source mounting part 20 and the inner wall of the lamp shade 10, there is a spatial distance for light propagation between the first light source 30 and the reflecting surface 12. Therefore, the light emitted by the first light source 30 can be emitted and irradiated. The light emitted by the first light source 30 irradiates the reflecting surface 12, and after being reflected, the light exits from the light outlet 11 for illumination. The second light source 40 is mounted on one side of the light source mounting part 20 facing the light outlet 11. The optical component 50 is mounted on the light source mounting part 20 and covers the second light source 40. The light emitted by the second light source 40 is adjusted by the optical component 50 and exits, and the light exiting from the optical component 50 exits from the light outlet 11 for illumination.

[0044] The lighting device provided by the embodiment of this application is applied to home lighting or office lighting. When the lighting device is in use for illumination, the first light source 30 emits light upward to irradiate the inner wall surface of the lamp shade 10 (that is, the first light source 30 emits light to irradiate the reflecting surface 12). After being reflected by the reflecting surface 12, the light exits from the light outlet 11 of the lamp shade 10 for illumination. The reflected light can illuminate downward evenly and softly, and this part of the illumination light forms indirect illumination light; the second light source 40 emits light downward to irradiate the optical component 50 for propagation adjustment. After being adjusted by the optical component 50 and exiting, the light can illuminate downward evenly and softly, and this part of the illumination light forms direct-view illumination light. In this way, the indirect illumination light and the direct-view illumination light are mixed and finally exit from the light outlet 11 for illumination. Compared with the lamps using direct illumination or indirect illumination in the related art, the light finally emitted by this lighting device for illumination is more uniform, soft and bright, does not glare at the user's eyes, reduces the harm degree of the glare light to the eyes, and meets the user's brightness requirement for the illumination light.

[0045] Embodiment 1:

[0046] As Figure 2 and Figure 4 shown, in the lighting device of Embodiment 1, the optical component 50 includes a first connecting portion 51, a lens plate 52, and a second connecting portion 53 that are connected in sequence. Among them, both the first connecting portion 51 and the second connecting portion 53 are located on the same side of the lens plate 52. Moreover, the side edge of the first connecting portion 51 away from the lens plate 52 is connected to the first edge 22 of the light source mounting portion 20, and the side edge of the second connecting portion 53 away from the lens plate 52 is connected to the second edge 23 of the light source mounting portion 20. The entire optical component 50 and the light source mounting portion 20 together enclose the second light source 40. Among them, at least a part of the light emitted by the second light source 40 is irradiated onto the lens plate 52 for propagation adjustment. When this part of the light exits from the lens plate 52 after being propagated and adjusted by the lens plate 52, not only can this part of the light be emitted evenly and softly after being propagated and adjusted by the lens plate 52, but also the beam angle of the emitted light can be reduced to improve the illumination brightness. This part of the light after exiting from the lens plate 52 irradiates towards the light exit 11 and exits for illumination, and this part of the light forms direct-view illumination light.

[0047] Furthermore, in order to make the direct-view illumination light be emitted more evenly and softly, therefore, as Figure 2 and Figure 4 shown, the optical component 50 further includes a first light source lens 54. The first light source lens 54 is installed on the side of the light source mounting portion 20 facing the light exit 11, and the first light source lens 54 covers the second light source 40. Among them, the first light source lens 54 is used to emit the light emitted by the second light source 40 after diverging propagation, so that the light emitted by the second light source 40 irradiates the lens plate 52 divergently (that is, the light emitted by the second light source 40 irradiates the lens plate 52 divergently after being propagated and adjusted by the first light source lens 54, so the light exiting from the first light source lens 54 has a very wide beam angle). In this way, the light emitted by the second light source 40 is spread out by the propagation of the first light source lens 54, so that the light becomes uniform and soft, and the beam angle of the emitted light can be reduced to improve the illumination brightness after being propagated and adjusted by the lens plate 52. In this way, comprehensively, it can not only meet the requirements of direct-view illumination brightness, but also emit light evenly and softly for illumination.

[0048] In the lighting device of Embodiment 1 of the present application, as Figure 2 and Figure 4 shown, the light source mounting portion 20, the first connecting portion 51, and the second connecting portion 53 are integrally formed. Moreover, as Figure 4 shown, the first connecting portion 51 is provided with a first card slot 511 at the edge away from the light source mounting portion 20, and the second connecting portion 53 is provided with a second card slot 531 at the edge away from the light source mounting portion 20. As Figure 4As shown, the two side edges of the lens plate 52 are respectively clamped in the first card slot 511 and the second card slot 531. That is, when assembling the lens plate 52, one end of the lens plate 52 is respectively inserted into the first card slot 511 and the second card slot 531, and then the lens plate 52 is pushed along the extending directions of the first card slot 511 and the second card slot 531, so that the two side edges of the lens plate 52 are completely clamped in the first card slot 511 and the second card slot 531, with convenient assembly and high efficiency.

[0049] As Figure 2 and Figure 4 shown, the lighting device further includes a second light source lens 60. The second light source lens 60 is installed on one side of the light source installation part 20 facing the inner wall of the lamp shade 10, and the second light source lens 60 covers the first light source 30. Among them, the second light source lens 60 is used to emit the light emitted by the first light source 30 after divergent propagation, so that the light emitted by the first light source 30 is divergently irradiated onto the reflecting surface 12. Therefore, the entire reflecting surface 12 is irradiated by light, and then the entire reflecting surface 12 emits light downward and irradiates the light outlet 11 and emits light for illumination, thereby obtaining uniform and soft indirect illumination light.

[0050] In this way, the indirect illumination light of the lighting device is mixed with the direct-view illumination light and finally emits light for illumination from the light outlet 11. The finally emitted illumination light is not only uniform and soft, but also meets the brightness requirements of users for the illumination light.

[0051] In the lighting device of the first embodiment of the present application, as Figure 3 and Figure 4 shown, the first light source 30 is symmetrically arranged with respect to the symmetry plane 21 of the light source installation part 20. And, as Figure 3 and Figure 4 shown, the second light source 40 is also symmetrically arranged with respect to the symmetry plane 21 of the light source installation part 20. Among them, at least one LED light strip is selected for assembling both the first light source 30 and the second light source 40. When multiple LED light strips are selected for the first light source 30 or the second light source 40, adjacent two LED light strips are arranged in parallel and at intervals on the light source installation part 20. And, the actual number of LED light strips used for the first light source 30 and the second light source 40 can be selected according to comprehensive factors such as the actual size of the lighting device and the lighting brightness requirements of the lighting site.

[0052] As Figure 1 and Figure 2As shown, the lamp cover 10 includes a first end plate 101, a second end plate 102, and a main body shell 103. The inner wall surface of the main body shell 103 is a reflecting surface 12, and the reflecting surface 12 is an arc surface. The first end plate 101 and the second end plate 102 are respectively connected to two ends of the main body shell 103, and two side edges of the main body shell 103, side edges of the first end plate 101, and side edges of the second end plate 102 enclose a light outlet 11. As Figure 1 and Figure 2 shown, the light source mounting part 20 and two ends of the optical component 50 are respectively connected to the first end plate 101 and the second end plate 102.

[0053] Furthermore, as Figure 1 and Figure 2 shown, the lighting device further includes a first end cover 71 and a second end cover 72. The first end cover 71 is connected to one end of the light source mounting part 20 and the optical component 50, and the second end cover 72 is connected to the other end of the light source mounting part 20 and the optical component 50. Moreover, the first end cover 71 is detachably connected to the first end plate 101, and the second end cover 72 is detachably connected to the second end plate 102. Among them, in the first embodiment of the present application, the first end cover 71 abuts against the inner side wall of the first end plate 101, and the first end cover 71 and the first end plate 101 are detachably connected by screws. The second end cover 72 abuts against the inner side wall of the second end plate 102, and the second end cover 72 and the second end plate 102 are also detachably connected by screws. That is to say, by using the first end cover 71 and the second end cover 72 to respectively cover two ends of the light source mounting part 20 and the optical component 50, the light source mounting part 20, the first light source 30, the second light source 40, the optical component 50, the second light source lens 60, the first end cover 71, and the second end cover 72 are formed into an integral module. Then, the integral module is placed into the lamp cover 10, so that the first end cover 71 abuts against the inner side wall of the first end plate 101, and the second end cover 72 abuts against the inner side wall of the second end plate 102. Then, the first end cover 71 and the first end plate 101 are locked by screws, and the second end cover 72 and the second end plate 102 are locked by screws.

[0054] In the first embodiment of the present application, the lighting device further includes a controller (not shown), which is electrically connected to the first light source 30 and the second light source 40. The controller controls the first light source 30 and the second light source 40 to select different lighting modes. Controlling the first light source 30 and the second light source 40 by the controller includes, but is not limited to, the following lighting modes: The controller simultaneously controls the first light source 30 and the second light source 40 to conduct. At this time, the indirect illumination light and the direct-view illumination light are mixed and finally emitted from the light-emitting port 11 for illumination; the controller controls the first light source 30 to conduct but does not control the second light source 40 to conduct. At this time, only the indirect illumination light is emitted from the light-emitting port 11 for illumination; the controller controls the second light source 40 to conduct but does not control the first light source 30 to conduct. At this time, only the direct-view illumination light is emitted from the light-emitting port 11 for illumination. Moreover, the controller can also control the magnitude of the driving current that drives the first light source 30 and the second light source 40 to emit light, so as to change the light output of the first light source 30 and the second light source 40, thereby changing the glare value of the lighting device and meeting the requirements for the glare value in different application scenarios.

[0055] Embodiment 2:

[0056] Compared with the lighting device of the first embodiment, the lighting device of the second embodiment has the following differences.

[0057] In the lighting device of the second embodiment of the present application, as Figures 6 to 8 shown, the light source mounting portion 20, the first connecting portion 51, the lens plate 52, and the second connecting portion 53 are integrally formed into a hollow member, and the second light source 40 is located in the hollow cavity. Among them, the light source mounting portion 20, the first connecting portion 51, the lens plate 52, and the second connecting portion 53 are integrally formed by using a diffusion material with a high transmittance, for example, prepared by an injection molding process.

[0058] In the lighting device according to the second embodiment of the present application, both the first connecting portion 51 and the second connecting portion 53 are provided as translucent, and further, the lens plate 52 is provided as translucent with a haze. Moreover, the light source mounting portion 20 is also translucent. In the second embodiment, the light emitted by the first light source 30 on the upper side of the light source mounting portion 20 is emitted in a divergent manner through the second light source lens 60 and irradiates upward to the reflecting surface 12 of the lamp cover 10. After being reflected, the light irradiates downward toward the light exit 11 and exits from the light exit 11 for lighting, forming indirect lighting light. The light emitted by the second light source 40 on the lower side of the light source mounting portion 20 is emitted in a divergent manner through the first light source lens 54 and irradiates divergently toward the first connecting portion 51, the lens plate 52, and the second connecting portion 53. Since the first connecting portion 51, the lens plate 52, and the second connecting portion 53 are all provided as translucent, therefore, the light is uniform and soft after being transmitted through the first connecting portion 51, the lens plate 52, and the second connecting portion 53. Among them, the light transmitted through the lens plate 52 irradiates toward the light exit 11 and directly exits for lighting. The light transmitted through the first connecting portion 51 and the second connecting portion 53 will be mixed with the light reflected downward by the reflecting surface 12 (or, the light transmitted through the first connecting portion 51 and the second connecting portion 53 fills the light reflected downward by the reflecting surface 12). This not only improves the brightness of the indirect lighting light, but also the soft reflected light is mixed with the soft light transmitted through the first connecting portion 51 and the second connecting portion 53 and still remains in a uniform and soft state, without being dazzling or causing glare.

[0059] Comparing the lighting device of the second embodiment with the lighting device of the first embodiment, except for the above differences, the remaining structures are the same, so they will not be described herein again.

[0060] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
