Description

Technical Field

[0001] The utility model relates to the field of lamps, in particular to a clear sky lamp. Background Art

[0002] Existing clear sky lamps include a housing, a first light source within the housing, a second light source located on the outer periphery of the housing, and Rayleigh scattering plates. When the first light source is turned on, it simulates sunlight; when the second light source is turned on, it shines onto the Rayleigh scattering plates around the housing, simulating a blue sky effect. Thus, the clear sky lamp can achieve the effect of natural sunlight and / or a blue sky on a sunny day.

[0003] However, the sun-simulating part and the blue sky part are set separately. If the first light source is not turned on and only the second light source is turned on, a dark side will be formed in the middle of the blue sky part, affecting the effect of the blue sky, and the blue sky effect is not ideal. If the first light source and the second light source are turned on at the same time to simulate the sun on a sunny day, the sun and the blue sky will be separated, and the natural sunny sun effect cannot be truly simulated, and the experience is not ideal. Moreover, the first light source usually has only one mode, that is, the first light source can only simulate the sun effect of a certain time period of the day. The sun effect is single, and the clear sky lamp cannot present a real natural sunny sun effect and make people feel that they are in a natural blue sky sun environment. Finally, due to the setting of the blue sky part, the existing clear sky lamp makes the lamp larger in size, occupies a large space, and is heavy, which is not convenient for installation and transportation.

It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0030] See also Figure 1-5The utility model discloses a clear sky lamp, comprising a shell 1 and a blue sky module and a solar module installed on the shell 1. A light outlet 11 is provided on the top of the shell 1. The light outlet 11, the blue sky module and the solar module are arranged in sequence from top to bottom.

[0031] The solar module includes a first light source 2 disposed at the bottom of a housing 1, wherein the number of the first light sources 2 is at least two and the color temperatures of the first light sources 2 are different; the blue sky module includes a Rayleigh scattering plate 4 and a second light source 3 disposed within the housing 1, wherein the second light source 3 is disposed outside the Rayleigh scattering plate 4; the Rayleigh scattering plate 4 is disposed between a light outlet 11 and the first light source 2, so that light from the first light source 2 passes through the Rayleigh scattering plate 4 and is irradiated toward the light outlet 11.

[0032] The light outlet, blue sky module and sun module of the clear sky lamp of the utility model are arranged in sequence from top to bottom, so that the light of the first light source of the sun module is irradiated to the light outlet through the Rayleigh scattering plate, simulating the blue sky sun effect formed by the sun shining on the blue sky. It can realistically simulate the natural sunny day sun effect, making the user feel as if they are in a natural sunny day sun environment, and the feeling effect is more ideal.

[0033] At the same time, the number of first light sources is at least two, and the color temperature of each lamp bead of the first light source is different. The first light source that matches the color temperature of the time period can be turned on accordingly according to different time periods of the day, thereby solving the problem of a single solar effect, simulating the clear sky and blue sky effect at different time periods, and presenting a real natural sunny sun effect that can make people feel like they are in a natural blue sky and sun environment, making the sunny sun natural environment effect more realistic and authentic.

[0034] In addition, since the blue sky module and the solar module are both installed on the shell, and the light outlet, blue sky module and solar module are arranged in sequence from top to bottom, the lamp structure is simple and compact, making the overall lamp small in size and light in weight, making it easy to install and transport.

[0035] The first light source 2 includes a red light source, a green light source, and a blue light source, and the ratio of the red light source, the green light source, and the blue light source is 24.3:42.1:33.5.

[0036] Specifically, the first light source 2 includes a first middle light source and a first noon light source, the color temperature value of the first middle light source is greater than the color temperature value of the first noon light source; the first middle light source is arranged in the middle of the shell, and the first noon light source is arranged on the side of the shell. In order to simulate the clear sky and blue sky effects at different time periods in nature, the sun rises in the east in the morning, and the first noon light source is on the side of the lamp to represent the sun rising in the east, and the first noon light source with a lower color temperature is turned on to simulate the sunlight effect at this time. At noon, the sun is at the highest point in the sky, and the first middle light source is in the middle of the lamp to represent the sun at noon, and the first middle light source with a higher color temperature is turned on to simulate the sun effect at this time. From afternoon to evening, the sun moves to the west, and the first noon light source is on the side of the lamp to represent the sun setting in the west, and the first noon light source with a lower color temperature is turned on to simulate the sun effect at this time.

[0037] Preferably, if Figure 4 As shown, the number of the first light sources 2 is at least three, including a first middle light source and two first noon light sources; the first light sources 2 are arranged in sequence along the extension direction of the shell 1, the first middle light source is arranged in the middle of the shell 1, and the first noon light sources are respectively arranged on both sides of the first middle light source. One of the first noon light sources lights up in the morning and is placed on one side of the lamp to simulate the morning sun rising in the east; the first middle light source lights up at noon and is placed in the middle of the lamp to simulate the noon sun in the middle of the sky; the other first noon light source lights up in the afternoon and is placed on the other side of the lamp to simulate the afternoon sun setting in the west. The combination of one first middle light source and two first noon light sources effectively simulates the effect of a clear sky and sunny day during the day, making the natural environment effect of the sun on a sunny day more realistic and authentic.

[0038] Wherein, the color temperature value range of the first medium light source is 2000-4000K to simulate the color temperature of the sun in the morning or afternoon. The color temperature value range of the first noon light source is 5000-7000K to simulate the color temperature of the sun at noon. Preferably, the color temperature value range of the first medium light source is 2500-3800K, and the color temperature value range of the first noon light source is 5500-6800K. More preferably, the color temperature value range of the first medium light source is 3000-3500K, and the color temperature value range of the first noon light source is 6000-6500K. More preferably, the color temperature value range of the first medium light source is 3500K, and the color temperature value range of the first noon light source is 6500K.

[0039] Specifically, such as Figure 3-5 As shown, the shell 1 includes a main shell 12 and a support frame 13, the light outlet 11 is arranged at the top of the main shell 12, and the first light source 2 is arranged at the bottom of the main shell 12; the support frame 13 is arranged inside the main shell 12, and the Rayleigh scattering plate 4 is placed on the support frame 13 so that the Rayleigh scattering plate 4 covers the top of the first light source 2.

[0040] The main housing has an opening at the top, which serves as a light outlet. The bottom of the main housing has a baseplate, on which a first light source is mounted. A support frame is placed. The support frame is hollow and extends through both end faces. A Rayleigh scattering plate is placed on the support frame, supporting the Rayleigh scattering plate. The Rayleigh scattering plate is positioned above the first light source, and light from the first light source passes through the Rayleigh scattering plate and illuminates the light outlet, simulating the effect of sunlight shining on the earth under a blue sky. The Rayleigh scattering plate is doped with nanoparticles. A second light source illuminates the Rayleigh scattering plate from the side, causing the incident light to Rayleigh scatter, creating the effect of a blue sky. The second light source 3 is mounted on the inner wall of the main housing 12, with its light-emitting surface facing the side of the Rayleigh scattering plate 4.

[0041] Preferably, as shown in the figure, the housing 1 further includes a pressing frame 14, which is installed in the main housing 12 through the light outlet 11 to press the Rayleigh scatter plate 4 against the support frame 13. The pressing frame acts on the Rayleigh scatter plate from above, pressing the Rayleigh scatter plate against the support frame, thereby fixing the Rayleigh scatter plate above the first light source.

[0042] Preferably, if Figure 2-5 As shown, the solar module further includes a mounting plate 5 fixedly mounted on the bottom of the main housing 12, and the first light source 2 is disposed on the mounting plate 5. The mounting plate is fixedly connected to the bottom plate of the main housing, and the first light source 2 is fixedly mounted on the mounting plate 5, thereby securing the first light source to the main housing.

[0043] Preferably, if Figure 3 As shown, the blue sky module also includes a light guide plate 6, which is positioned below the Rayleigh scatter plate 4. The second light source 3 is positioned outside the light guide plate 6. The light output surface of the second light source, located on the inner sidewall of the main housing, faces the side of the light guide plate. Light incident on the light guide plate is evenly reflected and refracted toward the Rayleigh scatter plate, where it is processed and then emitted. The light is refracted by the light guide plate and evenly illuminated by the Rayleigh scatter plate, creating a uniform blue sky effect.

[0044] More preferably, if Figure 3 As shown, the solar module also includes a diffuser plate 7, which is disposed below the light guide plate 6. Specifically, the Rayleigh scatterer plate 4, light guide plate 6, and diffuser plate 7 are sequentially arranged on the support frame 13 from top to bottom. Light from the first light source passes through the diffuser plate, light guide plate, and Rayleigh scatterer plate in sequence, and is emitted toward the light outlet. The provision of the diffuser plate makes the light emitted by the first light source more uniform, resulting in a more realistic sunlight illumination effect.

[0045] It should be noted that a glass lampshade is provided on the first light source, and the first light source achieves a light scattering effect on the first light source through the glass lampshade, so that the light is refracted and reflected in the glass, thereby changing the direction of the light and forming a certain halo to simulate the real sunlight effect.

[0046] Further, if Figure 3 、 5 As shown, the present invention also includes a lighting module mounted on the side wall of the shell 1, and the side wall of the shell 1 is provided with a mounting hole 15, and the mounting hole 15 is provided above the Rayleigh scattering plate 4; the lighting module includes a mounting base 8 and a third light source 9 provided in the mounting base 8, the mounting base 8 and the shell 1 are fixedly connected, and the light of the third light source 9 is irradiated into the shell 1 and toward the light outlet 11 through the mounting hole 15; the angle formed by the third light source 9 and the Rayleigh scattering plate 4 is a preset angle α.

[0047] Specifically, the mounting base 8 is fixedly connected to the main housing 12 so that the third light source 9 is fixedly mounted on the main housing 12, and the third light source 9 is arranged corresponding to the mounting hole 15, so that the light from the third light source 9 is irradiated into the main housing 12 through the mounting hole, and can be emitted from the light outlet after converging with the light from the first light source and the second light source. The third light source includes a light source board and lamp beads arranged on the light source board. The angle formed by the third light source and the Rayleigh scattering plate is a preset angle, which means that the angle between the plane where the light source board of the third light source is located and the plane where the Rayleigh scattering plate is located is a preset angle. The light from the third light source converges and intersects with the light from the first light source and the second light source under the limitation of the preset angle, and finally irradiates the wall. When observed directly with the human eye, the human eye feels the comfortable square light spot of the sun incident from the window, which simulates the effect of the sun shining into the room from outside the window.

[0048] Preferably, the preset angle α is 40°-70°. More preferably, the preset angle α is 45°-65°. More preferably, the preset angle α is 50°-60°. Even more preferably, the preset angle α is 55°. This preset angle helps the lighting module create a more realistic square light spot effect, providing a better user experience.

[0049] More preferably, if Figure 3 、 5 As shown, the lighting module also includes a reflector 10, which is positioned above the third light source 9. Light from the third light source is reflected by the reflector and directed toward the light outlet. This reflector, model GR20A-ZS6T-4545 from Zhongshan Keyi Optical Co., Ltd., facilitates the formation of a square light spot. This reflector can be constructed using existing technology and will not be described in detail here. The combination of the reflector and the preset angle creates a square light spot effect when sunlight enters through the window. In addition to the reflector, a lens can also be used.

[0050] In summary, the utility model provides a clear sky lamp, which has a highly realistic clear sky and blue sky effect and can simulate the clear sky and blue sky effects at different time periods.

[0051] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
