Description

Technical Field

[0001] This invention relates to the field of lighting, and in particular to an ambient light that controls the three-dimensional zoning of emitted light colors. Background Technology

[0002] With the development of the LED industry, lighting fixtures not only need to provide illumination but also need to have decorative and aesthetic functions, creating different atmospheres. Most colored ambient lights are difficult to assemble, or produce poor results, making mass production difficult or prohibitively expensive, hindering widespread adoption. Therefore, this invention designs a novel lighting fixture that uses specially designed optical components to regionalize and three-dimensionally represent different colors of light emitted by the light source.

[0003] Existing ambient light structures generally include a base A, a light source component B, and a housing. In order to create different lighting effects, there are generally two types of light source components. Both types of light source board structures have problems in terms of production cost, process, installation, lighting effect, shape, and power consumption. Summary of the Invention

[0004] To address the problems of existing color-separated lighting fixtures, this invention provides an ambient light that controls the three-dimensional zoning of emitted light colors.

[0005] This application proposes an ambient light with three-dimensional color zoning for controlling emitted light, comprising:

[0006] substrate;

[0007] A light-emitting unit is mounted on a substrate and includes a first light source and a second light source.

[0008] A beam splitting unit is mounted on the light-emitting unit and is configured to separate two light sources in the light-emitting unit into two beam angles with different beam angles, wherein the beam angle of the first light source is smaller than that of the second light source.

[0009] A diffuser is fitted over the substrate and forms a sealed space with the substrate. The light-emitting unit and the beam-splitting unit are placed in the sealed space.

[0010] The above technical solutions enable a variety of luminous color combinations, uniformly emitting colorful light on the same lamp, creating a three-dimensional effect in three-dimensional space, and are easy to install and low in cost.

[0011] Specifically, the diffuser is a spherical shape.

[0012] Specifically, the base contains a drive unit and a power supply unit; the power supply unit is an external power source or a battery; the drive unit enables at least two current outputs.

[0013] Specifically, the substrate contains a drive unit and a power supply unit; the power supply unit is an external power source or a battery; the drive unit enables at least two current outputs.

[0014] Specifically, the beam splitting unit includes a lens and an opaque cover.

[0015] In one alternative scheme, when both the first light source and the second light source are covered with lenses and opaque covers, the beam angles of the first light source and the second light source are constrained to any 10-20° between 0 and 50° and any 0-10° between 50 and 90°, and the lens covering the first light source is higher than the lens covering the second light source.

[0016] By placing TV lenses and opaque covers above the first and second light sources, and by controlling the TV lens above the first light source to be higher than that above the second light source, a slight difference in the beam angles of the two light sources is achieved, thus realizing the effect of four-layer partitioning using only two light sources.

[0017] In one alternative scheme, when a lens is placed over the first light source, the beam angle of the first light source is constrained to between 30 and 90°, and the beam angle of the second light source is 120°.

[0018] In the above technical solution, the lens covering the first light source can be a convex lens, a TV-like lens, etc., and this technical solution can achieve a color mixing effect in the overlapping part of the two light sources.

[0019] In one alternative scheme, when an opaque cover is placed over the first light source, the beam angle of the first light source is constrained to between 20 and 50°, and the beam angle of the second light source is 120°.

[0020] With the above technical solution, the transition area between the two light sources is small, making it suitable for achieving the effect of only two layers of color.

[0021] In one alternative scheme, when an opaque cover is placed over the first light source and a lens is placed over the second light source, the beam angle of the first light source is constrained to between 20° and 90°.

[0022] The lens used for the second light source can be a TV lens, and through the above technical solution, the light from the second light source will be projected onto the area not illuminated by the light from the first light source.

[0023] In one alternative scheme, when different types of lenses are used to cover the first and second light sources, the beam angles of the first and second light sources are constrained to between 40 and 85°.

[0024] Through the above technical solutions, the first light source can use a convex lens, a TV-like lens, or other focusing lens to control the projection area of ​​the first light source on the light emitter cover; the second light source can use a TV lens to achieve two-layer control of the entire lamp.

[0025] In one alternative scheme, the first light source and the second light source are respectively covered with an opaque cover and different types of lenses; the lenses include: TV lenses, convex lenses, and TV-like lenses. The lenses adopt a non-rotationally symmetric design, and the lens surface has scales or beads.

[0026] By designing a non-rotationally symmetric TV-like lens, the scales and beads on the lens surface cause the light source projected onto the diffuser to form a special light spot and present a three-dimensional pattern.

[0027] In one alternative scheme, lenses are mounted on the first and second light sources. The lenses are one-piece lenses, which are disc-shaped, and the upper surface of the lenses has a first raised ring and a second raised ring. The first raised ring completely covers the first light source, and the second raised ring completely covers the second light source. The diameter and height of the first raised ring are both smaller than those of the second raised ring.

[0028] With the above technical solutions, the light paths of the two light sources projected onto the diffuser are slightly different.

[0029] In one alternative embodiment, the substrate is a tower-like structure with a cylindrical protrusion in the middle, and the first light source is mounted on the side of the cylindrical protrusion, while the second light source is mounted on the top of the cylinder.

[0030] In the above technical solution, the first light source can be a green light bead, and the second light source can be a blue light bead.

[0031] In one alternative scheme, the first light source and the second light source are arranged in concentric circles. The first light source is arranged in the inner circle, and the second light source is covered with a lens. When the diffuser is an irregularly shaped arc that is wider at the top and narrower at the bottom, the beam angle of the second light source is constrained to between 15 and 40°.

[0032] Because a lens is placed above the second light source, the beam angle of the second light source is constrained, while the beam angle of the first light source is not constrained and diffuses naturally. Furthermore, due to the special shape of the diffuser, the mixing area between the two light sources is smaller.

[0033] The beneficial effects of this invention are:

[0034] 1. Multiple luminous colors are combined to uniformly emit colorful light on the same lamp, creating a three-dimensional effect in three-dimensional space;

[0035] 2. By using lenses and covers together, the color of light emitted from each position of the light-emitting cover can be precisely controlled;

[0036] 3. By using multiple light source arrangements or combinations of lenses and covers, different shapes can be formed by light shining through different colors onto the cover;

[0037] 4. Easy to install and low cost. Complex color combinations can be achieved using a simple structure and lens combination. Attached Figure Description

[0059] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and illustrate illustrative specific embodiments in which the present application may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0060] This application proposes an ambient light with three-dimensional color zoning for controlling emitted light, including:

[0061] substrate 4;

[0062] The light-emitting unit 5 is mounted on the substrate 4 and includes a first light source and a second light source.

[0063] A beam splitting unit is mounted on the light-emitting unit 5 and configured to separate two light sources in the light-emitting unit 5 into two beam angles, wherein the beam angle of the first light source is smaller than that of the second light source.

[0064] A diffuser 1 is fitted over the substrate 4 and forms a sealed space with the substrate 4. The light-emitting unit 5 and the beam-splitting unit are placed in the sealed space. The beam-splitting unit includes a lens 2 and an opaque cover 3.

[0065] The diffuser shroud 1 is a spherical shroud; the substrate 4 is equipped with a driving device and a power supply device; the power supply device is an external power source or a battery; the driving device realizes at least two current outputs.

[0066] Example 1:

[0067] like Figure 1 , Figure 2 and Figure 3 As shown, when both the first and second light sources are covered with lenses 2 and opaque covers 3, the beam angles of the first and second light sources are constrained to any 10-20° between 0 and 50° and any 0-10° between 50 and 90°. The lens 2 covering the first light source is higher than the lens 2 covering the second light source. TV lenses 2 and opaque covers 3 are placed above the first and second light sources. By controlling the TV lens 2 to be higher than that covering the second light source, the beam angles of the two light sources are slightly different, thus achieving the effect of four-layer partitioning using only two light sources.

[0068] Example 2:

[0069] like Figure 4 and Figure 5 As shown, when lens 2 is placed over the first light source, the beam angle of the first light source is constrained to between 30 and 90°, and the beam angle of the second light source is 120°.

[0070] Specifically, the first path has a convex lens, a TV-like lens, etc. The focusing lens makes the beam angle of the first path of LEDs vary between 30 and 90°, while the second path of LEDs has a beam angle of 120° without a lens, and the overlapping part shows a mixed color of the two paths of LEDs.

[0071] In the above technical solution, the lens 2 covering the first light source can be a convex lens, a TV-like lens, etc., and this technical solution can achieve the effect of color mixing in the overlapping part of the two light sources.

[0072] Example 3:

[0073] like Figure 6 and Figure 7 As shown, when the first light source is covered with an opaque cover 3, the beam angle of the first light source is constrained to between 20 and 50°, and the beam angle of the second light source is 120°. In this embodiment, the transition area between the two light sources is small, which is suitable for achieving the effect of only two layers of color.

[0074] Example 4:

[0075] like Figure 8 and Figure 9 As shown, when an opaque cover 3 is placed over the first light source and a lens 2 is placed over the second light source, the beam angle of the first light source is constrained to between 20° and 90°.

[0076] Specifically, the first path has an opaque cover 3, and the second path has a TV lens, etc. The first path LED uses a cover to reduce the beam angle, so that the beam angle varies between 20 and 90°, controlling the projection area on the cover. The second path LED uses a TV lens to control the light to the position not projected by the first path light, with two layers of control.

[0077] The lens used for the second light source can be a TV lens, and through the above technical solution, the light from the second light source will be projected onto the area not illuminated by the light from the first light source.

[0078] Example 5:

[0079] like Figure 10 , Figure 11 and Figure 12 As shown, when different types of lenses 2 are used to cover the first light source and the second light source, the beam angles of the first light source and the second light source are constrained to between 40 and 85°.

[0080] Specifically, the first path uses a convex lens or a TV-like lens, and the second path uses a TV lens. The first path uses a condenser lens 2 to control the projection area on the light emitter, while the second path uses another type of lens 2 to control the light within a range of 40 to 85 degrees, with two layers of control, one above the other.

[0081] Through the above technical solutions, the first light source can use a convex lens, a TV-like lens, or other focusing lens to control the projection area of ​​the first light source on the light emitter cover; the second light source can use a TV lens to achieve two-layer control of the entire lamp.

[0082] Example 6:

[0083] like Figure 13 and Figure 14 As shown, a lens 2 is mounted on the first light source and the second light source. The lens 2 is a one-piece lens, which is disc-shaped. The upper surface of the lens 2 has a first raised ring and a second raised ring. The first raised ring completely covers the first light source, and the second raised ring completely covers the second light source. The diameter and height of the first raised ring are both smaller than those of the second raised ring.

[0084] Specifically, a single-piece lens 2 is used to cover all the LED beads. Through the above technical solution, the light paths of the two light sources projected onto the diffuser are slightly different.

[0085] Example 7:

[0086] like Figure 15 and Figure 16 As shown, the substrate 4 is a tower structure with a cylindrical protrusion in the middle, and the first light source is installed on the side of the cylindrical protrusion, while the second light source is installed on the top of the cylinder.

[0087] Specifically, the first light source can use green LEDs, and the second light source can use blue LEDs.

[0088] Example 8:

[0089] like Figure 17 , Figure 18 and Figure 19 As shown, the first light source and the second light source are arranged in concentric circles. The first light source is arranged in the inner circle, and the second light source is covered with a lens 2. When the diffuser 1 is a circular arc-shaped part that is wider at the top and narrower at the bottom, the beam angle of the second light source is constrained to between 15 and 40°.

[0090] Specifically, the light source includes two RGB channels, with LEDs arranged in two circular rings. The inner ring is the first channel, using green LEDs, while the outer ring is the second channel, using blue LEDs. The second channel has a lens 2 to keep most of the light within a 15°-40° range; the first channel's light is naturally diffused.

[0091] In this embodiment, since the lens 2 is placed above the second light source, the beam angle of the second light source is constrained, while the beam angle of the first light source is not constrained and diffuses naturally. Furthermore, due to the special shape of the diffuser 1, the mixing area of ​​the two light sources is smaller.

[0092] It is obvious that those skilled in the art can make various modifications and alterations to the embodiments of this application without departing from the spirit and scope of this application. In this way, this application also aims to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered limiting in scope.
