Description

Technical Field

[0001] This invention relates to a lighting device, and more particularly to a blue sky lamp. Background Technology

[0002] With economic development and improved living standards, a healthy living environment has become a popular pursuit. For lighting fixtures, simulating natural light is the biggest challenge. In this context, the Skylight Lamp has emerged, designed to simulate the visual effect of the sky, providing a skylight-like illumination for indoor spaces that cannot be reached by sunlight.

[0003] Most existing sky lights simulate the visual effect of a sky by obliquely shining a light source onto a Rayleigh diffuser. To ensure uniform light output from the diffuser, a significant distance must be maintained between the light source and the light outlet, resulting in a larger overall thickness of the light fixture. Furthermore, this sky effect is relatively flat and differs considerably from a realistic clear sky.

[0004] In addition, to make the overall lighting fixtures more closely resemble the natural sky, some skylights also integrate lighting functions, with a specific, strong beam of light directed from the skylight to create an effect similar to sunlight shining through a window. However, due to the high brightness of this light, users may experience glare when viewing the blue sky module, affecting the user experience of the skylight. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a blue sky lamp that, in addition to providing a blue sky ambient lighting effect, can also be used as an indoor lighting fixture. The main lighting component is located on the side of the lamp, significantly reducing the overall height of the lamp.

[0006] To solve the above-mentioned technical problems, the present invention provides a blue sky lamp, including a lamp body, the lamp body having a blue sky cavity and an illumination cavity, the illumination cavity being located on one side of the blue sky cavity, the blue sky cavity having a first light outlet, and a blue sky module being provided inside the blue sky cavity;

[0007] The blue sky module includes a Rayleigh scattering plate and a first light source, the first light source being used to emit light onto the Rayleigh scattering plate;

[0008] The illumination cavity has a second light outlet, and a second light source is provided inside the illumination cavity. The light emitted by the second light source passes through the illumination cavity and exits from the second light outlet.

[0009] As an improvement to the above solution, the second light source includes a light-emitting component and a dimming component, wherein the light-emitting component is disposed in the dimming component; the dimming component includes a reflector and / or a convex lens.

[0010] As an improvement to the above scheme, the blue sky cavity and the lighting cavity are independent cavities, and the light-emitting component includes a combination of several LED beads with different fixed color temperatures or a single LED bead with adjustable color temperature.

[0011] As an improvement to the above solution, the blue sky cavity and the lighting cavity have a connecting channel, and the reflector cup has a light-transmitting hole that can communicate with the connecting channel.

[0012] As an improvement to the above solution, a diffuser plate is provided at the connection between the connecting channel and the blue sky cavity.

[0013] As an improvement to the above solution, the blue sky module also includes a shell and a semi-transparent and semi-reflective plate, both of which are disposed in the shell; the first light source is disposed on the inner wall of the shell and faces the Rayleigh scattering plate.

[0014] As an improvement to the above solution, the second light source further includes a light-transmitting cover that covers the surface of the dimming component.

[0015] As an improvement to the above solution, the lighting cavity is located at the junction of the bottom and side surfaces of the lamp body; the light-transmitting cover is arc-shaped, with its upper edge smoothly connected to the side surface of the lamp body and its lower edge smoothly connected to the bottom surface of the lamp body.

[0016] As an improvement to the above solution, the second light source also includes a rotating base, the side of which is provided with a rotating shaft, and the rotating base is connected to the lamp body through the rotating shaft; the light-emitting component and the dimming component are both disposed on the rotating base.

[0017] As an improvement to the above solution, several of the light-emitting components, reflectors, and convex lenses are arranged in a row on the rotating base to form a linearly arranged lighting structure; when the rotating base is at a predetermined angle, the light-transmitting hole is connected to the connecting channel.

[0018] As an improvement to the above solution, the connection channel corresponds one-to-one with the light-emitting component, and the connection channels are set at an angle to each other in the horizontal direction.

[0019] As an improvement to the above solution, the rotation axis of the rotating seat is also connected to a manual knob and / or a rotary motor.

[0020] As an improvement to the above solution, the dimming assembly further includes a mounting base, on which the reflector and / or convex lens are disposed;

[0021] The mounting base includes a positioning hole and a female buckle. The convex lens is provided above the positioning hole, and the reflector is provided with a female buckle. The reflector is fixed by engaging with the female buckle through the female buckle.

[0022] As an improvement to the above solution, the reflector cup includes an upper reflective surface and a lower reflective surface, wherein the tilt angle of the upper reflective surface is greater than that of the lower reflective surface.

[0023] Implementing this invention has the following beneficial effects:

[0024] In this embodiment, the second light source and the blue sky module are housed in separate cavities, allowing the luminaire to function as an indoor lighting fixture in addition to providing a blue sky ambient lighting effect. The main lighting component is positioned on the side of the luminaire, significantly reducing the overall height of the lamp and achieving surface mounting.

[0025] The second light source can be angled via a knob to match different installation distances, and its adjustable color temperature allows for changes in the emitted light color to meet the needs of different customer scenarios.

[0026] The light-emitting component emits light of corresponding color temperature according to the passage of time. Combined with the rotation of the rotating base, the angle of light illumination can be controlled to simulate the movement of the sun. Furthermore, in this embodiment, the light inlet of the connecting channel is positioned at a predetermined location, so that when the rotating base is at a predetermined angle, the light-transmitting hole is connected to the connecting channel, allowing the light emitted by the second light source to enter the blue sky cavity through the connecting channel. During the rotation of the rotating base, the light-transmitting hole and the connecting channel gradually align and then shift away from each other. During this process, the red light entering the blue sky cavity also gradually increases in size and then disappears. Through the clever design of the mechanical structure, a dynamic sunset effect is presented. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0035] like Figures 1-3 As shown, the first embodiment of the present invention provides a blue sky lamp, including a lamp body 100. The lamp body 100 has a blue sky cavity 101 and an illumination cavity 102. The illumination cavity 102 is located on one side of the blue sky cavity 101. The blue sky cavity 101 has a first light outlet 103. A blue sky module 200 is provided inside the blue sky cavity 101. The blue sky module 200 includes a Rayleigh diffuser 201 and a first light source 202. The first light source 202 is used to emit light towards the Rayleigh diffuser 201. The illumination cavity 102 has a second light outlet 104. A second light source 105 is provided inside the illumination cavity 102. The light emitted by the second light source 105 passes through the illumination cavity 102 and exits from the second light outlet 104.

[0036] In this embodiment, by setting different blue sky cavities 101 and lighting cavities 102 in the lamp body 100, the blue sky cavity 101 simulates a blue sky, while the lighting cavity 102 generates an illumination beam. The two do not interfere with each other, creating a lighting effect on the side of the lamp similar to sunlight shining through a window, making the overall lamp more closely resemble a natural sky. Furthermore, setting the lighting cavity 102 on one side of the blue sky cavity 101 avoids the overlapping of lighting elements, which would affect the thickness of the blue sky lamp, resulting in an ultra-thin blue sky lamp.

[0037] According to the second embodiment of the present invention, based on the first embodiment, a rotating structure is added to the second light source 105, so that the light emitted by the second light source 105 can be adjusted up and down, and finally project light spots of different heights.

[0038] Specifically, in combination Figure 3The blue sky module 200 is located at the bottom of the blue sky cavity 101, and also includes a shell 203 and a semi-transparent, semi-reflective plate 204. Both the Rayleigh scattering plate 201 and the semi-transparent, semi-reflective plate 204 are located within the shell 203. The first light source 202 is located on the inner wall of the shell 203 and faces the Rayleigh scattering plate 201. The Rayleigh scattering plate 201 is 5mm thick, and the semi-transparent, semi-reflective plate 204 is 2.5mm thick, with a transmittance of 50% and a reflectance of 50%. A 1mm high-transmittance transparent plate 205 can also be placed over the surface of the semi-transparent, semi-reflective plate 204 for protection. The materials of these plates can be PC, acrylic, or glass, etc. The plates can be tightly attached to each other or spaced 1-2mm apart; the gaps between the plates reduce watermarking caused by adhesion. The first light source 202 is positioned on the side of the Rayleigh scattering plate 201 in a side-emitting manner. The light source used has a color temperature of 6880-8100K, a main wavelength of 484nm, and a red ratio of 15.1%, a green ratio of 78.2%, and a blue ratio of 6.6%.

[0039] When the first light source 202 is activated, light enters the Rayleigh diffuser plate 201, where it is scattered by the micro-nano particles inside, creating a blue sky effect on its light-emitting surface. Testing the light-emitting surface with a lux meter reveals a red ratio of 12.6%, a green ratio of 35.9%, and a blue ratio of 51.5%, showing a significant improvement in the blue ratio. Some light is refracted downwards onto the semi-transparent, semi-reflective plate 204. This plate, with its single-sided coating, allows some light to be refracted into the plate and then reflected multiple times, creating a blue sky effect with superimposed blue light when the light is observed, enhancing the three-dimensionality and making the sky effect more transparent. The outermost layer is a high-transmittance transparent plate, its main function being to protect the Rayleigh diffuser plate 201 from dust and scratches without affecting the main light output effect.

[0040] The second light source 105 includes a light-emitting component 1 and a dimming component 2, wherein the light-emitting component 1 is disposed within the dimming component 2; the dimming component 2 includes a reflector 21 and / or a convex lens 22. Depending on specific requirements, the light-emitting component 1 may simultaneously include a reflector 21 and a convex lens 22, or it may only include one of them. The second light source also includes a light-transmitting cover 3, which covers the surface of the dimming component 2.

[0041] Preferably, the lighting cavity 102 is located at the junction of the bottom and side surfaces of the lamp body 100; the light-transmitting cover 3 is arc-shaped, with its upper edge smoothly connected to the side surface of the lamp body 100 and its lower edge smoothly connected to the bottom surface of the lamp body 100. By placing the lighting cavity 102 at the junction of the bottom and side surfaces of the lamp body 100, light can be emitted from both the side and bottom surfaces of the lamp, allowing for a large adjustment angle. The arc-shaped light-transmitting cover 3 reduces light focusing and shadows, as well as glare, thus providing a softer and more comfortable lighting effect. By smoothly connecting the upper edge of the light-transmitting cover 3 to the side surface of the lamp body 100 and its lower edge to the bottom surface of the lamp body 100, the structural strength between the light-transmitting cover 3 and the lamp body 100 is enhanced, reducing stress concentration caused by improper connection, thereby improving the durability of the lamp. The curved light-transmitting cover 3, together with the subsequent rotating base, can control different emission angles and form light spots at different heights on the wall.

[0042] Combination Figure 4 and Figure 5 As shown, to achieve control of the illumination height, the second light source also includes a rotating base 4. The rotating base 4 has a rotating shaft 41 on its side, and the rotating base 4 is connected to the lamp body 100 via the rotating shaft 41. The light-emitting component 1 and the dimming component 2 are both mounted on the rotating base 4. The rotating shaft 41 of the rotating base 4 is also connected to a manual knob 42 and / or a rotary motor. In this embodiment, the rotating shaft 41 of the rotating base 4 is connected to the manual knob 42, allowing the user to adjust the angle of the rotating base 4 by directly rotating the manual knob 42, thereby controlling the illumination height. In another embodiment, the rotating shaft 41 of the rotating base 4 is also connected to a rotary motor, allowing the rotating base 4 to swing up and down remotely or at set times, thereby automatically controlling the illumination height.

[0043] In some embodiments, the dimming assembly 2 further includes a mounting base 5, on which the reflector 21 and / or convex lens 22 are disposed. The mounting base 5 includes a positioning hole 51 and a female latch 52. The convex lens 22 is disposed above the positioning hole 51. The reflector 21 is provided with a female latch 211, and the reflector 21 is engaged and fixed with the female latch 52 through the female latch 211.

[0044] It should be noted that, using the above method, the mounting base 5 can be fixed to the rotating base 4 in advance using bolts or other means, and the base plate with the light-emitting component 1 can be pressed tightly onto the rotating base 4 by the mounting base 5. The mounting base 5 is provided with a positioning hole 51, in which the light-emitting component 1 is located. The convex lens 22 is located above the positioning hole 51 to converge the light emitted by the light-emitting component 1. The reflector 21 is located outside the convex lens 22 and is used to further converge and collimate the light processed by the convex lens 22 before directing its emission.

[0045] Preferably, the reflector cup 21 includes an upper reflective surface 212 and a lower reflective surface 213, wherein the tilt angle of the upper reflective surface 212 is greater than that of the lower reflective surface 213. By providing reflective surfaces with different reflection angles, the directionality of the emitted light can be further enhanced, and glare can be reduced.

[0046] Several light-emitting components 1, reflectors 21, and convex lenses 22 are arranged in a row on the rotating base 4 to form a linear lighting structure. This lighting structure can form a rectangular light spot on a wall or the ground. When the second light source illuminates the center of the wall, the angle between the reflector 21 and the blue sky module 200 is [degree]. Using this angle as a reference, the angle can be adjusted between 20° and 50° to accommodate different installation distances required by different customers. When the distance is too far, the adjustment angle of the second light source can be increased to ensure that the light spot remains on the wall and does not fall to the ground, thus affecting the overall effect. In this embodiment, the dimming component 2 includes both a reflector 21 and a convex lens 22. The blue sky cavity 101 and the lighting cavity 102 are independent cavities. The light-emitting component 1 includes a combination of several LED beads with different fixed color temperatures. When different color temperatures of light are required, the corresponding color temperature LED beads can be selectively illuminated. In other embodiments, the light-emitting component 1 can also be a single adjustable color temperature LED bead, which can generate light of different color temperatures by energizing different pins of the bead, simulating the light and shadow effect of sunlight shining through a window at different times. For example: Refer to Figure 6 In area A, during morning mode, the second light source angle is adjusted to 50 degrees, at which point the 4000K LED is illuminated; (Refer to...) Figure 6 In area B, during noon mode, the second light source angle is adjusted to 35 degrees, at which point the 5700K LED is illuminated; (Refer to...) Figure 6 In area C, during evening mode, the angle of the main secondary light source is adjusted to 20 degrees, at which point the 1800K LEDs are illuminated. Three different modes can be adjusted according to customer preference.

[0047] According to a third embodiment of the present invention, the difference from the second embodiment is that the blue sky cavity 101 and the lighting cavity 102 have a connecting channel 106, and the reflector 21 has a light-transmitting hole 214 that can communicate with the connecting channel 106. In this embodiment, the second light source 105 not only emits light outward to produce a light spot similar to sunlight, but also emits light into the blue sky cavity 101 through the connecting channel 106 to produce an effect similar to sunset.

[0048] Because the light from the second light source 105 is relatively strong, the diameter of the connecting channel 106 can be controlled, thereby controlling the light output of a single connecting channel 106. Furthermore, a diffuser plate 107 can be installed at the connection point between the connecting channel 106 and the blue sky cavity 101. The diffuser plate 107 converts the relatively strong light into softer light, illuminating the blue sky module 200 and creating the effect of a blue sky with reddish hues reminiscent of a sunset.

[0049] Preferably, a plurality of the light-emitting components 1, reflectors 21, and convex lenses 22 are arranged in a row on the rotating base 4 to form a linearly arranged lighting structure; when the rotating base 4 is at a predetermined angle, the secondary light-transmitting hole 43 and the light-transmitting hole 214 on the rotating base are connected to the connecting channel 106. Based on the specific implementation of the second embodiment, the light-emitting component 1 can emit light of a corresponding color temperature according to the passage of time, and in conjunction with the rotation of the rotating base 4, the angle of illumination of the light can also be controlled to simulate the effect of the sun moving. Furthermore, in this embodiment, the light inlet of the connecting channel 106 is set at a predetermined position, so that when the rotating base 4 is at a predetermined angle, the light-transmitting hole 214 is connected to the connecting channel 106, and the light emitted by the second light source 105 can enter the blue sky cavity 101 through the connecting channel 106. When the angle between the reflector 21 and the blue sky module 200 is set to 20 degrees, the light-transmitting hole 214 is connected to the connecting channel 106. That is, when simulating evening lighting, the light from the second light source 105 begins to enter the blue sky cavity 101, achieving a mechanically controlled sunset effect. At other times, a normal blue sky effect is achieved. During the rotation of the rotating seat 4, the light-transmitting hole 214 and the connecting channel 106 gradually shift from being directly aligned to being offset. During this process, the red light entering the blue sky cavity 101 also gradually increases in size and then disappears. Through the clever design of the mechanical structure, a dynamic sunset effect is presented.

[0050] Combination Figure 7 As shown, preferably, the connecting channel 106 corresponds one-to-one with the light-emitting component 1. The connecting channels 106 are set at an angle to each other in the horizontal direction, so that the light emitted from the connecting channel 106 intersects with each other, forming a sunset atmosphere with light and dark changes in different positions in the blue sky module 200, and enhancing the natural and realistic effect of the blue sky light.

[0051] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
