[0037] This embodiment provides a lamp that can be used on study tables, desks, office desks, etc., which can reduce the brightness change between the core area of the user's sight and the surrounding area on the desktop, and reduce the user's eye discomfort when switching visual scenes. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in , the lamp includes a lamp housing 1, a first light source 2, a second light source 3, a first diffuser plate 4 and a second diffuser plate 5. The lamp housing 1 includes a main housing 10, the main housing 10 is formed with a first receiving groove 100 and a second receiving groove 110, the first receiving groove 100 has a first light outlet, and the second receiving groove 110 has a second light outlet. The first light source 2 is arranged in the first receiving groove 100, the second light source 3 is arranged in the second receiving groove 110, the first diffuser plate 4 is arranged at the first light outlet, and the second diffuser plate 5 is arranged at the second light outlet. In this way, the light emitted by the first light source 2 is emitted through the first diffuser plate 4, and the light emitted by the second light source 3 is emitted through the second diffuser plate 5. In this embodiment, the orientation of the outer surface of the first diffuser plate 4 is different from the orientation of the outer surface of the second diffuser plate 5, so that the irradiation area of the first light source 2 is different from the irradiation area of the second light source 3.
[0038] The main housing 10 forms the first receiving groove 100 and the second receiving groove 110. The positions of the first light outlet and the second light outlet and the design of the opening direction can make the direction of the outer surface of the first diffuser plate 4 different from the direction of the outer surface of the second diffuser plate 5. In this way, the irradiation area of the first light source 2 located in the first receiving groove 100 can be different from the irradiation area of the second light source 3 located in the second receiving groove 110. When the lamp is applied to a table, one of the first light source 2 and the second light source 3 can be used to illuminate the core area on the tabletop, and the other can be used to illuminate the surrounding area, so that the core area used by the user and the surrounding area have similar brightness, which reduces the user's eye discomfort when switching visual scenes, reduces user eye fatigue, and protects the user's eyesight.
[0039] Specifically in this embodiment, combined with Figure 5 As shown in , in one embodiment, the lamp is applied to a study table, which includes a table body 9, which is formed with a table top 90. The table also includes the lamp provided in this embodiment, which is arranged on the table body 9, the lamp is located above the table top 90, and the outer surface of the first diffuser plate 4 in the lamp faces the table top 90. In this way, the core area on the desktop is illuminated by the light emitted by the first diffuser plate 4, while the light emitted by the second diffuser plate 5 illuminates the desktop environment. When the user's visual scene switches, since the light and dark changes of the visual scene are small, it will hardly cause eye discomfort.
[0040] Furthermore, in this embodiment, the opening directions of the first accommodating groove 100 and the second accommodating groove 110 are designed, thereby realizing the arrangement design of the first diffuser plate 4 and the second diffuser plate 5. Specifically, in this embodiment, the first diffuser plate 4 and the second diffuser plate 5 are arranged in parallel and the outer surfaces of the two are oriented in opposite directions, and the first diffuser plate 4 and the second diffuser plate 5 are arranged at intervals along the first direction and the second direction, the first direction is perpendicular to the first diffuser plate 4, and the second direction is parallel to the first diffuser plate 4. In this way, the light emitted by the first light source 2 and the light emitted by the second light source 3 are opposite to each other, and almost completely illuminate different areas.
[0041] Considering that the desktop of a table is generally rectangular, in order to make the core area of the desktop have a good lighting effect, the main shell 10 is designed to be long and strip-shaped in this embodiment, so that the light emitted by the first diffuser plate 4 can roughly fit the shape of the desktop. In addition, the main shell 10 in this embodiment is made by an extrusion molding process, and the long strip structure is easier to manufacture by an extrusion molding process. When the main shell 10 is designed to be long and strip-shaped, the inner wall of the first accommodating groove 100 is formed with a first mounting groove extending along the length direction of the main shell 10, and the inner wall of the second accommodating groove 110 is formed with a second mounting groove extending along the length direction of the main shell 10, the first light source 2 and the first diffuser plate 4 are inserted and positioned in the first mounting groove, and the second light source 3 and the second diffuser plate 5 are inserted and positioned in the second mounting groove.
[0042] Specifically in this embodiment, combined with Figure 4 , Figure 6 and Figure 7 As shown in the figure, the first installation slot includes two first slots 1000 with openings facing each other, the first light source 2 includes two first light strips in the shape of long strips, the lamp also includes a light guide plate 7 and two heat dissipation frames 6 adapted to the first slots 1000, and the two heat dissipation frames 6 are plugged into the first slots 1000 one by one. The two first light strips are inserted into the heat dissipation frames 6 one by one and fixed to the bottom wall of the heat dissipation frames 6, the light guide plate 7 and the first light diffuser 4 are arranged in a stacked and fitted manner, and the two sides of the two are respectively plugged into the heat dissipation frames 6. The above structural design enables the first light source 2 to illuminate the core area of the desktop in a side-lighting scheme, that is, the first light strips are arranged on the left and right sides respectively in a direction perpendicular to the desktop, and the light guide plate 7 is used to absorb the light emitted from the first light strip. When the light hits each light guide point on the light guide plate 7, the reflected light will diffuse to various angles, and then destroy the reflection condition and be emitted from the front of the light guide plate 7 and toward the light diffuser. The light guide plate 7 can emit light uniformly through various light guide points of different densities and sizes designed on the light guide plate 7. The light is then evenly irradiated onto the desktop through the diffuser plate to better protect the user's eyesight.
[0043] It is easy to understand that in other optional implementations, a lamp board with a larger width may be used as the first light source 2, the light guide plate 7 may be omitted, and the first light source 2 and the first diffuser plate 4 may be directly stacked.
[0044] Furthermore, considering that most tables such as study tables or desks are placed against the wall, the second light source 3 in this embodiment adopts an oblique polarized light illumination scheme, which can make the light better illuminate the interior of the space and enhance the light of the surrounding environment. Figure 6 and Figure 8 As shown in , the second mounting groove in this embodiment includes two second slots 1100 with two openings opposite to each other and two third slots 1101 with two openings opposite to each other, the second light source 3 includes a second light bar in the shape of a long strip, and the two side portions of the second light bar are respectively plugged into the second slots 1100, and the two side portions of the second diffuser plate 5 are respectively plugged into the third slots 1101, and the second light bar is tilted relative to the second diffuser plate 5.
[0045] like Fig.10 As shown in , when the lamp is in use, the first light source 2 adopts a side-lighting solution, and the second light source 3 adopts a polarized lighting solution. While making the brightness of the core area used by the user and the surrounding area similar, the core area and the surrounding area can also obtain good lighting effects, thereby better protecting the user's eyesight.
[0046] Combination Figure 3 , Figure 4 and Figure 6 As shown in , in order to facilitate user operation, the lamp also includes a controller 8, which can be a mechanical button, a knob, or an electronic touch screen. At the same time, the brightness of the light source can also be controlled by the controller 8. The main shell 10 in this embodiment is also formed with a fourth slot 120 extending along its length direction, and the main shell 10 is provided with an opening 150 on its side wall that is adapted to the size of the controller 8. The controller 8 is positioned in the fourth slot 120 and exposed through the opening 150. Specifically, in this embodiment, a snap-fit structure is provided between the outer shell of the controller 8 and the main shell 10. During installation, the controller 8 is directly pressed into the fourth slot 120 through the opening 150, and the controller 8 is positioned in the fourth slot 120 using the snap-fit structure. The working principle and snap-fit structure of the controller 8 are both prior art and will not be repeated here.
[0047] The first light source 2, the second light source 3 and the controller 8 all need to be electrically connected to an external power source or an internal battery. Figure 3 and Fig. 9As shown in , the main housing 10 in this embodiment is also formed with a wiring groove 140 along one end of its length direction, and the cables of the first light source 2 and the cables of the second light source 3 are both led to be electrically connected to the controller 8 through the wiring groove 140, and the cables of the controller 8 are led out of the lamp housing 1 through the wiring groove 140. In this way, the first light source 2 and the second light source 3 are both electrically connected to the controller 8, and at the same time, the first light source 2, the second light source 3 and the controller 8 are also electrically connected to the external power supply.
[0048] The lamp housing 1 in this embodiment also includes a support tube 12 and end caps 11 arranged at both ends of the main housing 10. In the related art, the lamp housing of this type of lamp generally includes a main body and a cover part, and an assembly port for assembly needs to be reserved in the main body, and the cover is used to close the assembly port. Specifically in this embodiment, the main housing 10 is the main body, and the end caps 11 at both ends of the main housing 10 are the covers. However, in the related art, the main body of the lamp housing needs to be divided into multiple parts to install and fix structures such as light strips and diffuser plates, which makes the main body of the lamp housing high in manufacturing cost and complicated in assembly. As mentioned above, the lamp provided in this embodiment, the main housing 10 in the lamp is made of plastic and extruded. In this way, only one piece of plastic board (such as PVC board) is needed to be integrally molded and manufactured through an extrusion molding process, which has the characteristics of less material consumption, less number of parts, convenient mold design or modification, etc., and can greatly reduce the manufacturing cost. At the same time, through the above-mentioned structural design of the main shell 10, various slot limit structures are formed inside it, and various components can be quickly installed into the main shell 10 directly through plug-in operations, which greatly simplifies the assembly operation.
[0049] In this embodiment, the main housing 10 and the end cover 11 are both made of plastic, wherein the main housing 10 is made of PVC and is extruded, and the end cover 11 is made of ABS and is injection molded. Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, a support tube 12 is further provided in the main housing 10, and the support tube 12 is used to support the main housing 10 as a whole. Specifically, the main housing 10 is further formed with a fifth slot 130 extending along its length direction, and the support tube 12 is inserted into the fifth slot 130 and its two ends extend out of the fifth slot 130. The end cover 11 covers the end of the main housing 10, and the end cover 11 is fixedly connected to the end of the support tube 12.
[0050] The end cover 11 in this embodiment adopts a split design, and the end cover 11 includes a base 111 and a cover 112, wherein the base 111 can cover the end of the main housing 10, and the cover 112 is fixedly connected to the base 111 by a snap-fit structure or screws. In this embodiment, a connecting plate 113 is also provided for the fixed connection between the end cover 11 and the support tube 12. Specifically, the connecting plate 113 is an L-shaped connecting piece, and a connecting hole is provided at the end of the support tube 12 extending out of the fifth slot 130. The connecting plate 113 and the end cover 11 are also provided with connecting holes, and the end cover 11, the support plate and the support tube 12 are fixedly connected by screws passing through the connecting holes.
[0051] Combination Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown in, the assembly process of the lamp is described in detail as follows: When assembling the first light source 2, firstly, the first light bar is bonded and fixed to the bottom wall of the heat dissipation frame 6, and the heat dissipation frame 6 is inserted into the first slot 1000. Then, the light guide plate 7 and the first diffuser plate 4 are inserted into the heat dissipation frame 6. When assembling the second light source 3, the second light bar is inserted into the second slot 1100, and the second diffuser plate 5 is inserted into the third slot 1101. When assembling the controller 8, the controller 8 is directly pressed into the fourth slot 120 from the opening 150 on the main housing 10 from the outside. The electrical connection cables of the first light source 2, the second light source 3 and the controller 8 are arranged through the wiring groove 140 at the end of the main housing 10. Afterwards, the support tube 12 is inserted into the fifth slot 130, and the two ends of the support tube 12 are respectively extended from the corresponding sides to the fifth slot 130. Then, the end caps 11 at both ends are fixedly connected to the ends of the support tube 12 using the connecting plate 113.
[0052] Finally, it should be noted that the above-mentioned implementation modes are only optional embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
