Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, specifically to a modular multifunctional table lamp system. Background Technology

[0002] Desk lamps are widely used in daily life, especially by students and office workers. There are many types of desk lamps, such as decorative desk lamps, bedside table lamps, and reading and writing desk lamps. Reading and writing desk lamps provide illumination for reading, writing, or similar activities. The pursuit of optimal lighting in desk lamps is paramount, and considerations must be given to average illuminance, illuminance uniformity, and glare control. Standards stipulate that in the central and edge areas where reading and writing are performed, the illuminance and illuminance uniformity of the lamp must at least reach Grade A, and ideally Grade AA. Grade A illuminance requirements are at least 300 lx in the central area and 150 lx at the edge; Grade AA illuminance requirements are at least 500 lx in the central area and 250 lx at the edge. The illuminance uniformity (ratio of maximum to minimum value) for both Grade A and AA lamps must not exceed 3. Reading and writing desk lamps must also provide light shielding; when a person is seated, the surface brightness of all light-emitting components as observed by the human eye should not exceed 2000 cd / m².

[0003] Currently, many desk lamps have put a lot of effort into functionality; however, their designs are relatively monotonous and fixed, lacking adaptability to different reading environments. Summary of the Invention

[0004] Based on the above problems, the present invention provides a modular multifunctional desk lamp system, which solves the problems that the current desk lamps are relatively monotonous and fixed in form, and lack adaptability to different reading environments.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0006] A modular multifunctional desk lamp system includes a base, a bracket, a lampshade, and multiple lighting mechanisms. The base and bracket are detachably connected, the lampshade and bracket are detachably connected, and the lighting mechanisms are hinged to the lampshade. Each lighting mechanism includes a lens barrel, an LED light, a lens, a light diaphragm, and an imaging module. The LED light, lens, light diaphragm, and imaging module are sequentially arranged inside the lens barrel according to the direction of light source illumination. The light diaphragm has a light-transmitting hole located at the focal point of the imaging module.

[0007] The imaging module includes, in sequence according to the direction of light source illumination, a first plano-convex lens, a negative lens, and a second plano-convex lens;

[0008] There are two combination schemes. Scheme 1 is as follows: the cross-section of the lens barrel is rectangular, the LED light is set on the wide side of one side of the lens barrel, and the lens, aperture and imaging module are arranged in sequence inside the lens barrel according to the direction of the light source illumination. The LED light, lens, aperture and imaging module are rotate symmetrical about the axis of symmetry parallel to the long side of the lens barrel.

[0009] The plurality of lighting mechanisms are hinged to the lampshade from top to bottom;

[0010] The light-transmitting hole is trapezoidal, and the opening size of the light-transmitting hole on the light barrier of the lighting mechanism arranged from top to bottom increases sequentially;

[0011] Option 2 is that the cross-section of the lens barrel is rectangular, the LED light is set on the wide side of one side of the lens barrel, the lens, the aperture and the imaging module are arranged in sequence inside the lens barrel according to the direction of the light source illumination, the LED light, the aperture and the imaging module are rotate symmetrical about the axis of symmetry parallel to the long side of the lens barrel, and the lens is a polarizing lens.

[0012] The plurality of lighting mechanisms are hinged to the lampshade from left to right;

[0013] The light-transmitting hole is trapezoidal, and the opening size of the light-transmitting hole on the light barrier of the lighting mechanism arranged from left to right decreases sequentially.

[0014] Furthermore, the lighting mechanism is connected to the lampshade via a ball joint connector.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the light emitted by the LED is collimated by the lens and shines on the light-transmitting hole on the light barrier. The light-transmitting hole plays a role in compensating for distortion. The light-transmitting hole is located at the focal position of the imaging module. Finally, the light shines on the imaging module through the light-transmitting hole and forms a light spot, which shines on the planar area. By using multiple lighting mechanisms hinged in the lampshade, the angle of the lighting mechanism can be adjusted according to different scene requirements, which solves the problem that the current table lamps are relatively monotonous and fixed in form, and lack adaptability to different reading environments.

[0026] The present invention will be further described below with reference to the accompanying drawings. Embodiments of the present invention include, but are not limited to, the following examples.

[0027] Example 1

[0028] like Figures 1-2 The modular multifunctional desk lamp system includes a base 1, a bracket 2, a lampshade 3, and multiple lighting mechanisms 4. The base 1 and bracket 2 are detachably connected, and the lampshade 3 and bracket 2 are detachably connected. The lighting mechanisms 4 are hinged to the lampshade 3 from top to bottom. Specifically, the base 1 and bracket 2 can be connected by bolts, and the lampshade 3 and bracket 2 can be connected by bolts. It should be noted that this includes, but is not limited to, the above detachable connection methods. The lampshade 3 is detachable. After disassembly, the lighting mechanisms 4 are connected to the lampshade 3 through a universal ball joint connector. The universal ball joint connector is a common connection method in the prior art, so it will not be described in detail. Finally, the lampshade 3 is assembled and can be used. The lampshade 3 is made of light-transmitting material.

[0029] like Figure 3 As shown, the imaging module includes a first plano-convex lens 406, a negative lens 407, and a second plano-convex lens 408 in sequence according to the direction of light source illumination. Specifically, the first plano-convex lens 406 and the second plano-convex lens 408 are made of the same material, have the same parameters, and are opposite in direction. The combination of the first plano-convex lens 406, the negative lens 407, and the second plano-convex lens 408 is beneficial for the correction of distortion and aberrations such as spherical aberration and chromatic aberration.

[0030] like Figure 3As shown, the cross-section of the lens barrel 402 is rectangular. The LED light 403 is located on the wide side of one side of the lens barrel 402. The lens 404, aperture 405, and imaging module are arranged sequentially inside the lens barrel 402 according to the direction of light source illumination. The LED light 403, lens 404, aperture 405, and imaging module are rotationally symmetrical about the axis of symmetry parallel to the long side of the lens barrel 402. A light-transmitting hole 5 is provided on the aperture 405, which is located at the focal point of the imaging module. Specifically, as shown... Figure 5 As shown, the light-transmitting aperture 5 is trapezoidal, and its function is to compensate for distortion. The lighting mechanisms 4 arranged sequentially from top to bottom have progressively larger opening sizes for the light-transmitting aperture 5 on their aperture 405. In use, the illumination area of ​​a single lighting mechanism 4 is 200mm. Multiple lighting units 4 are arranged vertically at a height of 500mm, which can illuminate the entire desktop. The top lighting unit 4 has the highest height, the smallest tilt angle, and the farthest illumination. Its corresponding light-transmitting hole 5 is the smallest. The lower the lighting unit 4 is, the larger the size of the light-transmitting hole 5 is, and the more light is emitted. The luminous flux driven by the corresponding LED light 403 light source gradually decreases. The purpose of this is to control the luminous flux of the light source of each lighting unit 4 so that the overall illumination is uniform.

[0031] like Figure 1 , Figure 4 As shown, when using it, the angle of each lighting mechanism 4 from top to bottom is adjusted in advance. After adjustment, the lampshade 3 is assembled and the LED light 403 is turned on. The light source emitted by the LED light 403 is collimated by the lens 404 and shines on the light-transmitting hole 5 of the light barrier 405. The light-transmitting hole 5 is located at the focal position of the lens 404 and finally shines on the imaging module to form a light spot. According to actual needs, the light spots formed by different lighting mechanisms 4 can illuminate different areas, or they can be superimposed to form a large area lighting.

[0032] Example 2

[0033] Compared with embodiment 1, embodiment 2 replaces lens 404, and the lighting mechanism 4 is arranged horizontally, specifically:

[0034] like Figure 6 , Figure 7 As shown, multiple lighting mechanisms 4 are hinged to the lampshade 3 from left to right. The light-transmitting holes 5 are trapezoidal, and the opening size of the light-transmitting holes 5 on the light barriers 405 of the lighting mechanisms 4 arranged from left to right decreases sequentially. Figure 8 , Figure 9 As shown, the cross-section of the lens barrel 402 is rectangular. The LED lamp 403 is set on the wide side of one side of the lens barrel 402. The lens 404, the aperture 405 and the imaging module are arranged in sequence inside the lens barrel 402 according to the direction of the light source illumination. The LED lamp 403, the aperture 405 and the imaging module are rotate symmetrical about the axis of symmetry parallel to the long side of the lens barrel 402. The lens 404 is a polarizing lens.

[0035] Since the lighting mechanisms 4 are arranged horizontally inside the lampshade 3, in order to control the luminous flux of each lighting mechanism 4 and make the overall illumination uniform, the leftmost lighting mechanism 4 has the smallest tilt angle and the closest illumination, and the corresponding light-transmitting hole 5 has the largest size. The further to the right, the smaller the size of the light-transmitting hole 5 becomes, and the less light is emitted. The corresponding LED light source 403 light source drive luminous flux gradually increases. In order to make the light output angle more reasonable, a polarizing lens is used to adjust the incident angle of the light source emitted by the LED light 403.

[0036] Example 3

[0037] Compared with Example 1, Example 3 is different in that the light-transmitting hole 5 can be replaced with other shapes. Under the effect of compensating for distortion, the light spot can form different patterns, which adds some fun when reading and writing is tiring and relaxes tense nerves.

[0038] The above are embodiments of the present invention.
