Description

Technical Field

[0001] The utility model relates to the technical field of optical lighting, and more specifically to an indirect lighting optical structure, a lamp housing and a lamp. Background Art

[0002] With the emergence and popularization of LED, the new design of lighting products has been greatly enriched, and various novel appearance lightings have appeared, and various indirect lighting systems with comfortable lighting as the theme have appeared. However, although the design of LED lighting in the current market is colorful and gorgeous, for pure lighting needs, no matter how the lighting is designed, it is always unavoidable to avoid light pollution caused by local bright lights. Even if anti-glare technology is used, the naked eye cannot look directly at the lighting fixture, which brings potential harm to people's eye health.

[0003] On this basis, indirect lighting is widely used in building decoration design. Through the projection of light sources, the space environment presents a different new visual experience. Indirect lighting is achieved by illuminating the secondary surface (such as the ceiling or wall) and providing light reflection from the secondary surface toward the object (or space) to be illuminated. Indirect lighting mainly relies on the light source, and the light of the light source is directed to the target, thereby achieving indirect lighting. The light source is hidden and cannot be seen directly, which is beautiful and safe, and effectively reduces the impact of glare.

[0004] However, since LEDs emit light in a unidirectional manner, they are not easy to scatter evenly, so the lighting angle and lighting effect of the overall indirect lighting optical structure cannot be effectively improved. In order to overcome this shortcoming, the most common way is to aggregate multiple LEDs with multi-angle distribution, but the light scattering effect that this method can produce is still limited and not perfect. In particular, when multiple LEDs are used, multiple light and shadows will overlap and overlap, and it is still impossible to effectively improve the irradiation effect at a certain position or angle.

[0030] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0031] The following is combined with Figure 1-8 The utility model is described in further detail.

[0032] Embodiment 1

[0033] like Figure 1-8 As shown, the utility model provides an indirect lighting optical structure, which includes a light incident side 1 for incident light, a reflection side 2 for reflecting light, and a light output side 3 for outputting the reflected light.

[0034] The working principle and beneficial effects of the above technical solution are:

[0035] The utility model discloses an indirect lighting optical structure, which has a light incident side 1 for incident light, a reflection side 2 for reflecting light and a light emitting side 3 for guiding the reflected light out. The light emitted by the light emitting structure 6 can be incident through the light incident side 1, reflected by the reflection side 2, and emitted to a preset position through the light emitting side 3, thereby effectively improving the light emission uniformity of the light emitting structure 6, making most of the light effectively utilized, improving the irradiation effect at a certain position or at a certain angle, reducing the situation where multiple light and shadows overlap and stagger, and ensuring the lighting effect.

[0036] Optionally, as a first embodiment of an indirect lighting optical structure, in the indirect lighting optical structure, the light incident side 1 includes an open light incident hole 1a, the light exit side 3 includes an open light exit hole 3a, and the reflection side 2 includes one or more annular reflection surfaces 2a; the light incident hole 1a is cooperatively arranged on one side of the one or more annular reflection surfaces 2a, and the one or more annular reflection surfaces 2a are cooperatively arranged on one side of the light exit hole 3a.

[0037] When the indirect lighting optical structure is used in conjunction with the light-emitting structure 6, the specific working principle and beneficial effects are as follows: the light emitted by the light-emitting structure 6 is incident on one or more annular reflective surfaces 2a in the structure through the light entrance hole 1a, and the one or more annular reflective surfaces 2a reflect the light so that the light is emitted through the light exit hole 3a and illuminated outward, which has a better effect on the utilization of light, plays a role in adjusting the light irradiation angle, and can improve the uniformity of irradiation.

[0038] Optionally, as a second embodiment of an indirect lighting optical structure, in the indirect lighting optical structure, the light incident side 1 includes a light incident panel 1b, the light emitting side 3 includes a light emitting panel 3b, and the reflection side 2 includes a total reflection panel 2b; the light incident panel 1b is cooperatively arranged on one side of the total reflection panel 2b, and the total reflection panel 2b is cooperatively arranged on one side of the light emitting panel 3b.

[0039] When the indirect lighting optical structure is used in conjunction with the light-emitting structure 6, the specific working principle and beneficial effects are as follows: the light emitted by the light-emitting structure 6 is incident on the total reflection panel 2b within the structure through the light input panel 1b, and the total reflection panel 2b reflects the light so that the light is refracted or transmitted through the light output panel 3b to illuminate the required position, effectively gather the light, and adjust the light illumination effect and illumination angle.

[0040] Optionally, as a third embodiment of an indirect lighting optical structure, based on the second embodiment of the indirect lighting optical structure, a reflector 4 is installed on the side of the total reflection panel 2b away from the light incident panel 1b. Through the setting of the reflector 4, the problem of light leakage of the total reflection panel 2b due to imperfections in optical design and manufacturing can be effectively solved, thereby ensuring the reflection effect and improving the light utilization rate.

[0041] The light incident side 1, the reflection side 2 and the light emitting side 3 are connected end to end to form an annular light distribution structure 7, and the light emitting side 3 is located on the outer side wall of the annular light distribution structure 7, so that the light emitted by the light emitting structure 6 is emitted from the outer side of the annular light distribution structure 7 to the position where it needs to be irradiated, thereby ensuring the illumination effect.

[0042] Embodiment 2

More than two upper mounting surface ears 502 are fixedly connected to the upper surface of the annular base 5. The annular light distribution structure 7 is sleeved on the outer surfaces of the multiple upper mounting surface ears 502. The upper mounting surface ears 502 are used to limit the annular light distribution structure 7 to ensure the stability of the installation of the annular light distribution structure 7. The central hole of the annular base 5 can also be used for wiring, which is convenient for reasonable wiring.

[0045] The lamp housing may be provided with multiple lamp housings, which are stacked and connected longitudinally, so as to facilitate the installation of a combination of multiple annular light distribution structures 7 and multiple light-emitting structures 6. More than two lower mounting surface ears 501 are fixedly connected in the central hole of the annular base 5. When a combination of multiple annular light distribution structures 7 and multiple light-emitting structures 6 needs to be installed, the upper mounting surface ear 502 between two adjacent lamp housings can be connected with the lower mounting surface ear 501. Through holes or threaded holes are provided on the upper mounting surface ear 502 and the lower mounting surface ear 501. The two lamp housings are rotated at a certain angle around their axis so that the lower mounting surface ear 501 of the upper support body 100 and the upper mounting surface ear 502 of the lower support body 100 overlap, and then they can be connected by bolts, which is very convenient for installation or disassembly.

[0049] The light emitted by multiple LED light sources can be incident from the light incident side 1 into the annular light distribution structure 7, and reflected by the reflection side 2 inside the annular light distribution structure 7, and then the reflected light is guided out through the light output side 3 of the annular light distribution structure 7, so that the illumination is uniform and the effect is good.
