Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to a ceiling lamp with low glare and high light efficiency. Background Art

[0002] Glare is a phenomenon that causes eye discomfort or reduced ability to observe objects due to an unreasonable distribution of brightness in the field of vision or excessive brightness fluctuations. Specifically, it manifests as: extremely bright light from the light source or reflective surface, or a large brightness difference between the center of the field of vision and the background brightness. This brightness difference can reduce people's visual function and cause discomfort.

[0003] Existing ceiling lights offer high brightness, high operating power, and high installation heights. Furthermore, their structural design rarely considers anti-glare, resulting in strong glare in actual use. To address this issue, a small number of ceiling light manufacturers opt to combine ceiling lights with reflectors and diffusers for anti-glare treatment. However, since the light emitted from the diffuser to the center of the reflector remains free and uncontrolled, this can lead to an uneven transition between the main and secondary light spots, further causing stratification.

[0019] The lamp beads are arranged toward the focusing ring;

[0020] Lamp beads are evenly distributed within the vertical projection range of each of the focusing rings;

[0037] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0038] The most critical concept of this utility model is that: through the focusing ring on the lens, the path of freely diverging light can be controlled so that the light can be evenly hit on the reflector, thereby avoiding the phenomenon of light stratification and glare. At the same time, the distance between the lens and the lighting end of the light source assembly can be adjusted according to actual lighting needs to change the lighting range and avoid the problem of light path overlap or inadequate lighting between different lamps.

[0039] Please refer to Figures 1 to 5 The utility model provides a low-glare and high-light-efficiency ceiling lamp, comprising a light source assembly 1, a lens 2, and a reflector 3 with openings at both ends;

[0040] The light source assembly 1 is connected to one end of the reflector 3, and the lighting end of the light source assembly 1 is arranged toward the other end of the reflector 3;

[0041] The lens 2 is disposed inside the reflector 3, and a preset distance is set between the lens 2 and the lighting end of the light source assembly 1;

[0042] At least two concentric focusing rings 21 are provided on one end of the lens 2 away from the light source assembly 1 .

[0043] Specifically, the focusing rings 21 are arranged closely together, and the initial distance between the lens 2 and the lighting end of the light source assembly 1 can be adjusted according to the regulatory requirements of different countries and regions.

[0044] From the above description, it can be seen that the beneficial effect of the utility model is: to provide a low-glare and high-light-efficiency ceiling lamp, which can control the path of freely divergent light through the focusing ring 21 on the lens 2, so that the light can be evenly hit on the reflector 3, thereby avoiding the phenomenon of light stratification and glare; compared with existing ceiling lamps, it can not only achieve anti-glare effect, but also adjust the distance between the lens 2 and the lighting end of the light source assembly 1 according to actual lighting needs, thereby changing the lighting range of the light, and then avoiding the problem of light path overlap or inadequate lighting between the lamps, which affects the user's viewing experience.

[0045] Furthermore, the focusing ring 21 and the lens 2 are an integrated structure;

[0046] The outer surface of the focusing ring 21 is an arc surface, and the ridge of the arc surface is away from the lighting end of the light source assembly 1 .

[0047] As can be seen from the above description, the design has made specific optimizations to the structure of the focusing ring 21, so that the multiple concentrically arranged focusing rings 21 all have a focusing effect similar to that of the convex lens 2, which can change the light distribution at different positions to adjust the direction, angle or intensity of the light, thereby achieving the effect of controlling glare and light spots.

[0048] Furthermore, at least three waist-shaped holes 22 are evenly distributed on the edge of the lens 2;

[0049] The circular path formed by the extension direction of the waist-shaped hole 22 is coaxially arranged with the focusing ring 21;

[0050] The light source assembly 1 is slidably connected to the lens 2 through the waist-shaped hole 22 .

[0051] Furthermore, a connecting member 11 is provided on the light source assembly 1;

[0052] A lifting track 221 is provided on the inner wall of the waist-shaped hole 22 near one end of the light source assembly 1;

[0053] The connecting member 11 is slidably connected to the lens 2 via the lifting rail 221 .

[0054] Specifically, the lifting paths of the lifting rails 221 in each waist-shaped hole 22 have the same direction, that is, when the lens 2 is rotated clockwise or counterclockwise, the lowest points 222 of all the lifting rails 221 gradually approach the connecting piece 11 until the inner wall of the waist-shaped hole 22 conflicts with the connecting piece 11.

[0055] As can be seen from the above description, this design has made specific improvements to the structure of the lens 2 and the connection method between the lens 2 and the light source assembly 1; when it is necessary to adjust the distance between the lens 2 and the lighting end of the light source assembly 1 to change the illumination range of the light, this effect can be achieved simply by rotating the lens 2, that is, when it is necessary to expand the distance between the lens 2 and the lighting end of the light source assembly 1, the lowest point 222 of the lifting track 221 can be moved close to the connecting member 11; conversely, by moving the highest point 223 of the lifting track 221 close to the connecting member 11, the effect of reducing the distance between the lens 2 and the lighting end of the light source assembly 1 can be achieved.

[0056] Furthermore, the light source assembly 1 includes a base plate 12 and lamp beads 13 arranged on the base plate 12;

[0057] The lamp beads 13 are arranged toward the focusing ring 21;

[0058] The lamp beads 13 are evenly distributed within the vertical projection range of each focusing ring 21;

[0059] From the center to the periphery of the lens 2 , the number of the lamp beads 13 within the vertical projection range of each focusing ring 21 gradually increases.

[0060] From the above description, it can be seen that when the rated output current of the light source assembly 1, the rated current of the lamp bead 13, the rated light transmittance of the lamp bead 13 and the number of parallel branches of the lamp bead 13 are determined, the corresponding light quantity of the light source can be obtained; because the arc length of the focusing ring 21 gradually increases from the center to the periphery of the lens 2, when the light quantity remains unchanged, if the lamp beads 13 are arranged on the base plate 12 in a dot matrix manner, the overall luminous density will gradually weaken from the center to the periphery of the lens 2, thereby causing the problem of uneven lighting; therefore, by evenly distributing the lamp beads 13 within the vertical projection range of each focusing ring 21, and further ensuring that the number of lamp beads 13 within the vertical projection range of each focusing ring 21 from the center to the periphery of the lens 2 gradually increases, an uneven arrangement with sparse inside and dense outside is formed, thereby effectively improving the uniformity of lighting.

[0061] Furthermore, the reflector 3 is a bowl-shaped structure;

[0062] The small end of the reflector 3 is connected to the light source assembly 1 , and the lighting end of the light source assembly 1 is arranged toward the large end of the reflector 3 .

[0063] Specifically, the structure of the reflector 3 is similar to that of any commercially available compound parabolic concentrator, and the depth of the reflector 3 and the diameter of the large end of the reflector 3 can be adjusted according to the specific size of the ceiling light.

[0064] From the above description, it can be seen that the bowl-shaped structure is a deep cavity structure that gradually converges from the small end to the large end. The light source component 1 is set at the small end of the reflector 3, so that the light emitted by the light source component 1 can achieve a gathering effect under the action of the reflector 3, thereby effectively controlling the emission angle of the light, that is, within a certain angle range, forming an ideal light distribution model, improving the uniformity of the entire surface light source, and making the light spot soft, so as to achieve precise control of the light, thereby avoiding the occurrence of stratification, dark rings and other phenomena.

[0065] Furthermore, the above-mentioned low-glare and high-light-efficiency ceiling light further includes a radiator 4;

[0066] The light source assembly 1 is connected to the reflector 3 via a heat sink 4 .

[0067] As can be seen from the above description, an excessively high operating temperature will not only affect the overall lighting effect, but will even severely shorten the service life of the light source assembly 1 . The above situation can be effectively avoided by providing a heat dissipation cover.

[0068] The low-glare and high-light-efficiency ceiling lamp of the utility model can be used for daily lighting work.

[0069] Please refer to Figures 1 to 5 , the first embodiment of the present utility model is:

[0070] A low-glare, high-light-efficiency ceiling light comprises a radiator 4, a light source assembly 1, a lens 2, and a reflector 3 with openings at both ends; the light source assembly 1 is connected to one end of the reflector 3 via the radiator 4, with the illuminating end of the light source assembly 1 facing the other end of the reflector 3; the lens 2 is disposed within the reflector 3, with an initial spacing of 1.1 mm between the lens 2 and the illuminating end of the light source assembly 1; six concentric focusing rings 21 are provided at the end of the lens 2 away from the light source assembly 1; the reflector 3 is a bowl-shaped structure; the small end of the reflector 3 is connected to the light source assembly 1, with the illuminating end of the light source assembly 1 facing the large end of the reflector 3.

[0071] The focusing ring 21 and the lens 2 are an integral structure; the outer surface of the focusing ring 21 is an arc surface, and the bulge of the arc surface is away from the lighting end of the light source assembly 1; ten waist-shaped holes 22 are evenly distributed on the edge of the lens 2; the circular path formed by the extension direction of the waist-shaped holes 22 is coaxially arranged with the focusing ring 21; the light source assembly 1 is slidably connected to the lens 2 through the waist-shaped holes 22.

[0072] The light source assembly 1 is provided with a connector 11, a base plate 12, and a lamp bead 13 arranged on the base plate 12; a lifting track 221 is provided on the inner wall of the waist-shaped hole 22 near one end of the light source assembly 1; the connector 11 is slidably connected to the lens 2 through the lifting track 221; the height difference between the lowest point 222 and the highest point 223 of the lifting track 221 is 2mm, which is the focusing stroke of the ceiling light. By adjusting the position of the connector 11 on the lifting track 221, the lighting end of the lens 2 and the light source assembly 1 can be adjusted. The lifting paths of the lifting rails 221 in the waist-shaped holes 22 are in the same direction, that is, when the lens 2 is rotated clockwise or counterclockwise, the lowest points 222 of all the lifting rails 221 gradually approach the connecting piece 11 until the inner wall of the waist-shaped hole 22 conflicts with the connecting piece 11; the lamp beads 13 are arranged toward the focusing ring 21; the lamp beads 13 are evenly distributed within the vertical projection range of each focusing ring 21; along the direction from the center to the periphery of the lens 2, the number of lamp beads 13 within the vertical projection range of each focusing ring 21 gradually increases.

[0073] The working principle of the present invention is as follows: before the ceiling lights leave the factory or are prepared for installation, the staff can confirm the required number of ceiling lights according to the size of the space of the place to be illuminated and the lighting requirements to be met, and adjust the illumination range of the light according to the spacing between each ceiling light. That is, when the illumination range is too large, by rotating the lens 2, the lowest point 222 of the lifting track 221 is close to the connecting piece 11, the distance between the lens 2 and the lighting end of the light source assembly 1 can be expanded, thereby reducing the illumination angle to 60° to narrow the illumination range; conversely, when the illumination range is too small, the lens 2 is rotated in the opposite direction, so that the highest point 223 of the lifting track 221 is close to the connecting piece 11, the distance between the lens 2 and the lighting end of the light source assembly 1 can be reduced, thereby increasing the illumination angle to 90° to expand the illumination range; thereby avoiding the problem of light path overlap or inadequate lighting between the lamps, which affects the user's viewing experience.

[0074] The difference between the second embodiment of the present invention and the first embodiment is that:

[0075] The initial spacing between the lens 2 and the lighting end of the light source assembly 1 is 0.3 mm; the height difference between the lowest point 222 and the highest point 223 of the lifting track 221 is 1.7 mm; this design makes the distance between the initial position of the lens 2 and the lighting end of the light source assembly 1 closer, thereby improving the overall lighting range. At the same time, the light angle can be converted from 90° to 60° through only a focusing stroke of 1.7 mm, thereby effectively improving the adjustment efficiency.

[0076] To sum up, the utility model provides a low-glare and high-light-efficiency ceiling light, which can control the path of freely diverging light through the focusing ring on the lens, so that the light can be evenly hit on the reflector, thereby avoiding the phenomenon of light stratification and glare; compared with existing ceiling lights, it can not only achieve an anti-glare effect, but also solve the problem of light path overlap or inadequate lighting between each lamp, which affects the user's viewing experience.

Any equivalent transformations made using the contents of the present invention specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
