Description

Technical Field

[0001] The present invention relates to the field of lighting technology, and in particular to an up-and-down light-emitting lighting fixture and an ultra-thin lighting fixture. Background Art

[0002] In the existing lighting technology field, as the main lighting device for indoor spaces, chandeliers are usually designed with a single downward light-emitting mode, that is, a light source (such as an LED, a fluorescent lamp, or an incandescent lamp) projects light intensively onto the lower area through a lampshade or a reflector. Although this design can effectively meet the direct lighting needs of specific areas such as workbenches and dining tables, its inherent technical limitations have gradually emerged, specifically manifested as follows:

[0003] 1. Contrast between local strong light and shadow: The single downward lighting causes the light distribution to be "cone-shaped focused", and there is a significant brightness difference between the illuminated area and the non-illuminated area (such as the ceiling and walls), forming a strong contrast between light and dark. Staying in such a light environment for a long time is likely to cause visual fatigue and even lead to glare problems;

[0004] 2. Lack of ambient light: The ceiling and walls appear dim due to the lack of light reflection, and effective indirect lighting (ambient light) cannot be formed, making the overall space appear depressing and lacking in a sense of hierarchy;

[0005] 3. Space compression effect: Only the downward lighting will make the ceiling area fall into darkness, visually reducing the floor height and generating a "space oppression feeling", which is especially unfavorable for small-sized or low-floor buildings;

[0006] In view of the above background art, we have provided a new technical solution. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention proposes an up-and-down light-emitting lighting fixture, and the technical solution adopted is as follows:

[0008] An up-and-down light-emitting lighting fixture includes a lamp head. In the middle of the lower end surface of the lamp head, there is an LED main light source, and on its upper end surface, there is an LED top light source. The LED main light source emits light downward, and the LED top light source is an annular light source that emits light upward; on the lamp head, there is an anti-glare cover, and the light inlet hole of the anti-glare cover is directly opposite to the LED main light source, and its light outlet is arranged downward.

[0009] According to an up-and-down light-emitting lighting fixture of an embodiment of the present invention, a light-shielding ring is provided on the side edge of the lamp head.

[0010] According to an up-and-down light-emitting lighting fixture of an embodiment of the present invention, the lamp head is provided with an LED side light source on its upper end surface. The LED side light source is an annular light source and is arranged vertically on the upper end surface of the lamp head.

[0011] A top and bottom light-emitting lighting fixture according to an embodiment of the present invention is provided with a light-transmitting lampshade on the lamp head. The upper end of the light-transmitting lampshade is fixedly connected to the upper end of the lamp head, and the lamp head is covered within the light-transmitting lampshade.

[0013] A top and bottom light-emitting lighting fixture according to an embodiment of the present invention, wherein a clamping hole is provided on the outer periphery of the lower end face of the lamp head, and a clamping head is provided on the top of the anti-glare cover. The clamping head is cooperatively clamped into the clamping hole to install and fix the anti-glare cover on the lamp head.

[0014] A top and bottom light-emitting lighting fixture according to an embodiment of the present invention, wherein a radiator is fixedly connected above the lamp head.

[0015] A top and bottom light-emitting lighting fixture according to an embodiment of the present invention, wherein the lamp head is provided with a light source installation cavity thereon, a reflector cup seat is arranged in the light source installation cavity, the LED main light source is arranged on the top of the reflector cup seat, and a reflector cup is fixedly sleeved under the reflector cup seat.

[0037] The present invention provides an up-and-down light-emitting lighting fixture. In the first and second embodiments, as Figures 1 to 8As shown, it includes a lamp cap 10. In the middle of the lower end face of the lamp cap 10, there is an LED main light source 20, and on its upper end face, there is an LED top light source 30. The LED main light source 20 emits light downward, and the LED top light source 30 is an annular light source that emits light upward. A glare shield 50 is provided on the lamp cap 10. The light inlet hole of the glare shield 50 is directly opposite to the LED main light source 20, and its light outlet is arranged downward.

[0038] The present invention provides an up-and-down light-emitting lighting fixture. The LED main light source 20 is arranged in the middle of the lower end face of the lamp cap 10, responsible for direct downward lighting, providing main illumination light, and providing high-brightness direct lighting for the working area (such as a desktop or the ground). The LED top light source 30 is arranged on the upper end face of the lamp cap 10, used to project light upward. The light forms soft ambient light after being diffusely reflected by the ceiling, improving the overall brightness of the space. The glare shield 50 is used to optimize the light distribution of the main light source, reduce glare, and improve visual comfort. Through the design of up-and-down dual light sources, the present invention provides both direct lighting and indirect ambient light at the same time, reduces the contrast between light and dark, and improves the comfort of the space. The ceiling reflected light can effectively eliminate shadows, avoiding the problem of "local overbrightness and surrounding overdarkness" of traditional chandeliers. The upward lighting can improve the brightness of the ceiling, visually increase the floor height, and avoid the "depressing feeling" of traditional downlighting fixtures. The annular top light source design makes the light distribution more uniform, avoiding local overexposure caused by point light sources, and effectively solving the problems of narrow lighting range and insufficient ambient light of traditional chandeliers.

[0039] Furthermore, in the first and second embodiments of the present invention, as shown in Figures 2, 3, and 8, a light shielding ring 60 is provided on the side edge of the lamp cap 10, used to block the lateral light leakage of the LED top light source 30, ensuring that the light is mainly projected upward to the ceiling, avoiding the influence of stray light on the lighting effect, avoiding unnecessary lateral glare, improving the lighting purity, ensuring that the upward light is more concentratedly projected to the ceiling, improving the indirect lighting efficiency, and reducing the waste of light energy. Especially when the lamp body is suspended relatively low, the light shielding ring 60 can prevent the light from directly shining into people's eyes. Combining the glare shield 50 (downlighting control) and the light shielding ring 60 (uplighting control) realizes omnidirectional anti-glare.

[0040] Further, in the first and second embodiments of the present invention, as shown in Figures 2, 4, 5, 6, and 8, the lamp head 10 is provided with an LED side light source 40 on its upper end face. The LED side light source 40 is a ring-shaped light source and is arranged perpendicular to the upper end face of the lamp head 10. On the basis of the original LED main light source 20 (downward illumination) and LED top light source 30 (upward illumination), the present invention further optimizes the light environment adjustment ability, adds lateral supplementary lighting, which is mainly used for wall washing illumination or creating a spatial atmosphere, enhances the spatial sense of hierarchy. The light shielding ring 60 can optimize the light distribution of the side light source, avoid the downward scattering of light, and ensure that it is mainly used for indirect illumination in the horizontal direction. The present invention realizes omnidirectional glare-free illumination through a five-dimensional optical system of the main light source (downward illumination) + top light source (upward illumination) + side light source (horizontal) + anti-glare cover 50 + light shielding ring 60 (as shown in Figure 9 ), covering the lower, upper, and lateral directions, without dazzling stray light.
