Technical Field
[0001] The utility model belongs to the technical field of learning lamps, in particular to a learning lamp capable of supplementing ambient light. Background Art
[0002] A learning lamp is a lamp placed on a desk and used to provide illumination required for learning. It is generally used when the ambient light is poor or the light is blocked by the human body. A learning lamp generally only has a light-emitting body that emits light to one side. By adjusting the angle of the bracket of the learning lamp, the irradiation angle of the light-emitting body is adjusted, and then illumination is provided.
[0003] However, when the ambient light is dim, in order to ensure the illumination effect, the irradiation direction of the light-emitting body is generally perpendicular or approximately perpendicular to the desktop, and the concentrated light will not illuminate other positions, so that the ambient light will not be improved. However, studying in dim ambient light will also cause damage to eyesight. Summary of the Utility Model

[0018] The following further details the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein does not limit the protection scope of the present invention.
[0019] As Figures 1 to 5 shown, it is a schematic structural diagram of the learning lamp capable of supplementing ambient light provided by the present invention. The learning lamp capable of supplementing ambient light comprises a lamp head 10 and two brackets 20 arranged on the lamp body 10. The learning lamp capable of supplementing ambient light further comprises some other functional modules, such as a controller of a power cord connected to the lamp head 10, etc., which should be well-known technologies to those skilled in the art and will not be described in detail herein one by one.
[0020] The lamp head 10 includes a lamp housing 11, a fixing plate 12 disposed within the lamp housing 11, an upper lamp board 13 disposed on top of the fixing plate 12, a back diffusion plate 14 covering the upper lamp board 13, a cover plate 15 covering the back diffusion plate 14, a lower lamp board 16 disposed at the bottom of the fixing plate 12, a surface diffusion plate 17 disposed at the bottom of the lower lamp board 16, a prism plate 18 disposed at the bottom of the surface diffusion plate 17, and a plurality of press strips 19 disposed between the lower lamp board 16 and the surface diffusion plate 17.
[0021] The lamp housing 11 is made of opaque aluminum alloy, having the advantages of high strength, light weight and durability. Both the top and bottom of the lamp housing 11 are through holes, and the cover plate 15 and the prism plate 18 are respectively mounted on the through holes, so that the lamp housing 11 forms a sealed housing. A wire protection sleeve 112 is inserted at one end of the lamp housing 11. The wire protection sleeve 112 communicates with both the inside and outside of the lamp housing 11, and the power cord connected to the upper lamp board 13 and the lower lamp board 16 passes through the wire protection sleeve 112. The wire protection sleeve 112 is made of silicone rubber.
[0022] The fixing plate 12 is horizontally disposed within the lamp housing 11 and is used to provide mounting positions for the components within the lamp housing 11. The fixing plate 12 is a semi-rigid aluminum plate. The upper lamp board 13 and the lower lamp board 16 are respectively fixedly disposed on the fixing plate 12 by screws or snap fasteners.
[0023] A plurality of LED lamp beads are disposed on the upper lamp board 13. The LED lamp beads on the upper lamp board 13 are disposed on the top of the upper lamp board 13. The LED lamp beads on the upper lamp board 13 are arranged to form two symmetric long strips, so that the light emitted by the upper lamp board 13 is more evenly distributed.
[0024] The back diffusion plate 14 is disposed on the top of the upper lamp board 13. The back diffusion plate 14 is used to evenly process the light emitted by the upper lamp board 13. The back diffusion plate 14 completely covers the LED lamp beads on the upper lamp board 13.
[0025] Two light-transmitting holes 151 are formed in the cover plate 15. The light-transmitting holes 151 are respectively strip-shaped and symmetrically disposed on the cover plate 15. The light-transmitting holes 151 are used to pass the light that has passed through the back diffusion plate 14. The black sealing strip 131 is EVA foam, and the black sealing strip 13 is used to increase the sealing performance of the lamp housing 11 and block the leakage of light inside the lamp body 10.
[0026] A plurality of LED lamp beads are disposed at the bottom of the lower lamp board 16. The lower lamp board 16 is used to provide downward light.
[0027] The surface diffusion plate 17 and the prism plate 18 are sequentially arranged at the bottom of the lower lamp panel 16, which can uniformly process the light emitted by the lower lamp panel 16 and prevent the generation of glare.
[0028] One side of the bead 19 abuts against the lamp housing 11, and the other side abuts against the surface diffusion plate 17. A retaining ring 111 is provided on the lamp housing 11, and the bottom of the prism plate 18 abuts against the retaining ring 111, so that the bead 19 presses and mounts the surface diffusion plate 17 and the prism plate 18 on the lamp housing 11. The bead 19 includes a plurality of long beads 191 and a plurality of short beads 192, and the long beads 191 and the short beads 192 are arranged to form a ring body, which is clamped between the lamp housing 11 and the surface diffusion plate 17.
[0029] During installation, the prism plate 18 and the surface diffusion plate 17 are sequentially placed inside the lamp housing 11, and then the bead 19 is press-fitted on the surface diffusion plate 17. After that, the lower lamp panel 16, the fixing plate 12, the upper lamp panel 13 and the back diffusion plate 14 are sequentially placed on the bead 19, wherein the lower lamp panel 16, the fixing plate 12 and the upper lamp panel 13 are pre-fixed to form an integral body. Finally, the cover plate 15 is covered on the back diffusion plate 14 and glued to the lamp housing 11.
[0030] It should be noted that the upper lamp panel 13 and the lower lamp panel 16 are respectively connected to a controller, so that the upper lamp panel 13 and the lower lamp panel 16 can be controlled to emit light simultaneously or separately. The upper lamp panel 13 and the lower lamp panel 16 are respectively connected to a power cord (not shown in the figure), and the power cord passes through the wire protection sleeve 112 and is connected to an external power supply to supply power to the upper lamp panel 13 and the lower lamp panel 16.
[0031] During use, when the ambient light is insufficient, the upper lamp panel 13 and the lower lamp panel 16 are turned on simultaneously. The lower lamp panel 16 will provide light for illuminating the desktop, while the upper lamp panel 13 will illuminate the ceiling and the surrounding areas, so that the area near the study lamp is evenly illuminated. Since the light-transmitting holes 151 on the cover plate 15 are in strip shape and the light intensity of the illumination environment is lower than that of the illumination on the desktop, a large amount of light can be prevented from directly shining into the eyes through the light-transmitting holes 151 and affecting the eyesight.
[0032] The bracket 20 is L-shaped. An installation piece 21 is respectively provided at both ends of the lamp housing 11. The installation piece 21 is horizontally arranged. One end of the bracket 20 is bolted to the installation piece 21, so that it can be fixedly arranged on the lamp housing 11.
[0033] Compared with the prior art, the learning lamp capable of supplementing ambient light provided by the present utility model is provided with an upper lamp panel 13 and a lower lamp panel 16. A cover plate 15 is covered on the upper lamp panel 13. Two light-transmitting holes 151 are formed in the cover plate 15. The light of the upper lamp panel 13 is emitted from the light-transmitting holes 151 to illuminate the top and the surrounding of the lamp head 10, thereby enhancing the ambient light. Thus, when the ambient light is insufficient, it can play a role in improving the ambient brightness, and further protect eyesight.
[0034] The above are only the preferred embodiments of the present utility model and are not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements or improvements within the spirit of the present utility model are all covered within the scope of the claims of the present utility model.
