Abstract
Description
Technical Field
[0001] This application relates to the field of lighting technology, and more particularly to a mixed-light luminaire. Background Technology
[0002] With the development of the LED lighting and IoT industries, non-smart lighting can no longer meet modern lighting needs. The technological focus of lighting has shifted from conventional lighting to the era of smart lighting integrated with the Internet of Things. Along with the development of smart lighting, RGB light sources are increasingly being used in the lighting industry.
[0003] Currently, RGB light sources are mainly used as ambient lighting in LED lighting products, and are not truly used as main lighting. That is, most products on the market use RGB and white light sources separately, and there are very few products that use RGB mixed light as main lighting.
[0004] Especially in spotlight products, most can only emit a single color of light, and cannot achieve the mixing of multiple different monochromatic lights. This makes spotlights relatively limited in creating atmosphere and lighting effects, and unable to meet the diverse needs of different scenarios. For example, in some parks, courtyards, or landscape areas that require a specific color atmosphere, single-color lights cannot create rich and unique visual effects.
[0005] Secondly, existing lawn lights also have problems with the distribution of light zones. Even though some lights attempt to achieve different colors of illumination through multiple light sources, the limitations of lens design often result in abrupt and harsh transitions between light zones, lacking a natural gradation effect. These abrupt edges of the light zones are not only visually unappealing but can also lead to unevenness and disharmony in the illuminated area. Summary of the Invention
[0006] This application provides a light mixing fixture that can mix multiple different beam angles, resulting in a uniform and coordinated color mixing effect in overlapping areas, and a natural and soft gradient effect in the transition of non-overlapping areas.
[0007] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:
[0008] In a first aspect, this application provides a light mixing fixture, including a light source and a lens. The light mixing fixture includes: the light source including a first light source and at least one second light source, the first light source and the second light source being disposed adjacent to each other; the lens including a first lens and at least one second lens; the first lens being disposed on the light-emitting surface of the first light source to form a first beam angle; the second lens being disposed on the light-emitting surface of the second light source to form a second beam angle; the first beam angle and the second beam angle at least partially overlap.
[0009] In some specific embodiments, the second light source may be positioned around the periphery of the first light source.
[0010] In some specific embodiments, when the second beam angle is greater than or equal to the first beam angle, the angle range of the first beam angle is 20° to 90°, and the angle range of the second beam angle is 30° to 110°.
[0011] In some specific embodiments, when the second beam angle is smaller than the first beam angle, the angle range of the first beam angle is 30° to 110°, and the angle range of the second beam angle is 60° to 100°.
[0012] In some specific embodiments, the second light source is disposed to the side of the first light source, so that the first beam angle and the second beam angle overlap.
[0013] In some specific embodiments, the first beam angle is 20° to 110°, and the second beam angle is 20° to 110°.
[0014] In some specific embodiments, the light mixing fixture further includes a reflector cup disposed around the periphery of the first light source and the second light source, for reflecting the light from the first light source and the second light source to the first lens area and the second lens area, respectively.
[0015] In some specific embodiments, the light source is an RGB LED.
[0016] In some specific embodiments, the number of the second light source is one or two.
[0017] In some specific embodiments, the mixed-light luminaire also includes a control module and a lamp housing.
[0018] This application provides a light mixing fixture, including a light source and a lens. The light mixing fixture includes: the light source includes a first light source and at least one second light source, the first light source being disposed adjacent to the second light source; the lens includes a first lens and at least one second lens; the first lens is disposed on the light-emitting surface of the first light source to form a first beam angle; the second lens is disposed on the light-emitting surface of the second light source to form a second beam angle; the first beam angle and the second beam angle at least partially overlap, which not only makes the light mixing effect of the overlapping part uniform and coordinated, but also allows the transition of the non-overlapping part to present a natural and soft gradient effect, improving the user experience.

[0025] This application proposes a mixed-light luminaire, such as Figure 1 As shown in Figure 2, the mixed light fixture includes a light source 100, a lens 200, a reflector 300, a control module 400, and a lamp housing 500. The lens 200 is disposed on the light-emitting surface of the light source 100, and the reflector 300 is disposed on the periphery of the light-emitting surface of the light source. The control module 400 is electrically connected to the light source 100 to control the optical parameters of the light source 100. The lamp housing 500 is provided with a receiving space for accommodating the light source 100, the lens 200, the reflector 300, and the control module 400.
[0026] In some embodiments of this utility model, the light source 100 can be a white LED, an RGB LED, or a hybrid unit composed of white LEDs and RGB LEDs.
[0027] To better illustrate this utility model, in the following embodiments, the light source 100 is an RGB LED bead, and the first light source 110 and the second light source 120 emit monochromatic light of different colors.
[0028] In one embodiment of this utility model, the light source 100 includes a first light source 110 and a second light source 120, the lens 200 includes a first lens 210 and a second lens 220, and the reflector 300 includes a first reflector 310 and a second reflector 320. The first lens 210 is disposed on the light-emitting surface of the first light source 110, the first reflector 310 is disposed at the periphery of the light-emitting surface of the first light source 110, the second lens 220 is disposed on the light-emitting surface of the second light source 120, and the second reflector 320 is disposed at the periphery of the light-emitting surface of the second light source 120.
[0029] When the first light source 110 is lit, the light, through the cooperation of the first reflector 310 and the second lens 210, forms a first angle of light distribution from the light-emitting surface of the first lens 210, and the beam angle of the first light distribution is the first beam angle A; when the first light source 120 is lit, the light, through the cooperation of the second reflector 320 and the second lens 220, forms a second angle of light distribution from the light-emitting surface of the first lens 220, and the beam angle of the second light distribution is the second beam angle B.
[0030] In one embodiment of the present invention, the second light source 120 is a ring-shaped array of LED beads, and the second light source 120 is arranged around the periphery of the first light source 110. Figure 2a A schematic diagram of the first beam angle A of a mixing lamp according to an embodiment of the present invention. Figure 2b This is a schematic diagram of the second beam angle B of a mixing lamp according to an embodiment of the present invention. Figure 2c This is a schematic diagram showing the overlap of the first beam angle A and the second beam angle B of a mixing lamp according to an embodiment of the present invention, as shown below. Figure 2a , Figure 2b and Figure 2c As shown, the first beam angle A and the second beam angle B of the mixing lamp can overlap. By overlapping the first beam angle A and the second beam angle B, light mixing between light sources with different parameters of the first and second light sources is achieved, which improves the uniformity and brightness of the light mixing in the overlapping area and enhances the user experience.
[0031] In some embodiments of this utility model, the range of the first beam angle is 20° to 110°, and the range of the second beam angle is 20° to 110°.
[0032] In some other embodiments of this utility model, the first beam angle ranges from 20° to 90°, and the second beam angle ranges from 30° to 110°.
[0033] When the first beam angle A is smaller than the second beam angle B, that is, the angle range of the first beam angle A is 30° to 110° and the angle range of the second beam angle B is 60° to 100°, the light in the overlapping part of the first beam angle A and the second beam angle B mixes to achieve a light mixing effect, improve the light mixing uniformity and brightness of the overlapping area, and the edge of the overlapping part of the first beam angle and the second beam angle can also present a natural transition gradient effect.
[0034] When the first beam angle A and the second beam angle B are the same, the light in the overlapping part of the first beam angle A and the second beam angle B is mixed to achieve a light mixing effect, thereby improving the light mixing uniformity and brightness of the overlapping area.
[0035] In another embodiment of this utility model, when the first beam angle A is greater than the second beam angle B, the light in the overlapping part of the first beam angle A and the second beam angle B is mixed to achieve a light mixing effect, thereby improving the light mixing uniformity and brightness of the overlapping area. Furthermore, the edge of the overlapping part of the first beam angle and the second beam angle can also present a natural transition gradient effect.
[0036] In one embodiment of this utility model, the second light source 120 is disposed on one side of the first light source 110. Figure 3a A schematic diagram of the first beam angle of a mixing lamp according to an embodiment of the present invention. Figure 3b This is a schematic diagram of the second beam angle of a mixing lamp according to an embodiment of the present invention. Figure 3c This is a schematic diagram showing the overlap of the first beam angle and the second beam angle of a mixing lamp according to an embodiment of the present invention. The first beam angle and the second beam angle of the mixing lamp can overlap. By overlapping the first beam angle and the second beam angle, light mixing between light sources with different parameters of the first light source and the second light source is achieved, which improves the uniformity of light mixing in the overlapping area and enhances the user experience.
[0037] like Figure 3c As shown, when the first beam angle A is smaller than the second beam angle B, the light in the overlapping part of the first beam angle A and the second beam angle B mixes to achieve a light mixing effect, improve the light mixing uniformity and brightness of the overlapping area, and the edge of the overlapping part of the first beam angle and the second beam angle can also present a natural transition gradient effect.
[0038] When the first beam angle A and the second beam angle B are the same, the light in the overlapping part of the first beam angle A and the second beam angle B is mixed to achieve a light mixing effect, thereby improving the light mixing uniformity and brightness of the overlapping area.
[0039] In another embodiment of this utility model, a second light source 120 is provided on both the upper and lower sides or the left and right sides of the first light source 110 to achieve a similar effect. Figure 3c The light mixing effect.
[0040] This invention achieves a high degree of light mixing uniformity and brightness through the cooperation of a specially designed light source, lens, and reflector, and by utilizing the overlapping cooperation between multiple beam angles. Furthermore, when there are different beam angles, the edges between the overlapping and non-overlapping parts can produce a natural transition gradient effect. It is not only suitable for professional lighting but also for excellent entertainment lighting, thus improving the user experience.
