Description

A PROJECTION LAMP FOR SIMULATING A SKY EFFECT
2017279839 29 Dec 2017
TECHNICAL FIELD [0001] The present invention relates to the field of projection lamps, and specifically to a projection lamp for simulating a sky effect.
BACKGROUND [0002] Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
[0003] Lamp lighting is an important means to decorate and beautify the environment and create artistic atmosphere. It is very important to use decorative lamps to decorate the interior space, increase the space level, and render the atmosphere. In the environmental design of the modem home architecture, theater buildings, commercial buildings and entertainment buildings, lamp lighting even becomes a part of the entirety of the design. Lamps not only play a role in ensuring lighting, their shape, material, color, proportion, and scale are also attached much importance to. Lamps have become an indispensable decoration of the interior space. In order to add rich and colorful fun to the living environment of the people, lighting designers give full play to the role of the shine and color of lighting by the means of rhythmically controlling the lighting and shade, looming, rising and falling, strength and weakness of the light, and use the transmission, reflection and refraction of the light and other means to create a warm and soft, quiet and elegant, romantic, brilliant, magnificent, happy, fast-paced, mysterious, confusing and other artistic atmosphere [0004] In addition, in order to enrich the means of the lighting design, there are pattern projection lamps in the prior art. Projecting the previously designed patterns onto the surface of the object through lighting is often used as an advertising means in some occasions, in addition to playing role of a decoration. Projecting the propaganda object as a pattern onto the surface of the object through a pattern projection lamp achieves the purpose of advertising at the same time, in addition to decorative effects. However, the stripe or pattern projected by the existing pattern projection lamp is usually inflexible. Natural phenomena, such as the sky, cannot be simulated and reproduced indoors vividly through a pattern projection lamp, which is a great pity for the general public without a panorama room of 360°.
SUMMARY [0005] In view of the above, in order to overcome at least one of the above deficiencies
2017279839 29 Dec 2017 described in the prior art, the preferred embodiments of theinvention provide a projection lamp for simulating a sky effect with a simple structure and realistic effect.
[0006] In order to solve the above technical problems, the preferred embodiments of the invention use one or more of the following technical solutions:
[0007] A projection lamp for simulating a sky effect, comprising a first light-emitting component, wherein the first light-emitting component comprises a first light source for generating a first light ray, a first frosted glass arranged on an optical path of the first light ray and a convex lens, which are sequentially arranged, and the first light ray emitted by the first light source is projected onto a surface through the first frosted glass and the convex lens to exhibit a cloud effect.
[0008] In an embodiment a first frosted glass is set between the first light source and the convex lens. The first light ray emitted by the first light source exhibits a cloud effect shaped like cotton on one surface after passing through the first frosted glass and the convex lens so as to achieve the purpose of creating a sky effect indoors. At least one surface of the first frosted glass is naturally corrugated, so that the pattern projected after being refracted by the first frosted glass and then re-converged by the convex lens is more natural and more vivid. The convex lens re-converges the first light ray refracted through the first frosted glass to prevent the first light ray from being too scattered to be imaged in a relatively short distance. In diagram of the imaging effect, the degree of the curvature of the surface of the convex lens facing the first light source is preferably smaller than that of the other surface away from the first light source. It’s widely believed that the sky is blue. Thus, in order to improve the degree of vividness, the blue light may be used as the first light source.
[0009] In addition to the daytime sky and the cloudy night sky, a viewer may often see the shadow of stars in the sky. For this purpose, the projection lamp for simulating a sky effect further comprises a second light-emitting component, wherein the second light-emitting component comprises a second light source for generating a second light ray and a grating plate arranged on an optical path of the second light ray, and the second light ray emitted by the second light source is projected onto a surface through the grating plate to exhibit a star effect. The second light ray exhibits a star-like pattern on one surface through the grating plate so as to exhibit a vivid starry sky indoors.
[0010] Due to the effect of the air flow, irregular motion and irregular shape changes usually occur in the clouds. For this purpose, the projection lamp for simulating a sky effect further comprises a driving device, wherein the first frosted glass and/or the grating plate are in driving connection with the driving device, respectively, and when the first frosted glass and/or the
2017279839 29 Dec 2017 grating plate move under the control of the driving device, the first light ray emitted by the first light source is projected onto one surface through the first frosted glass and the convex lens to exhibit a changing cloud effect, and/or the second light ray emitted by the second light source is projected onto one surface through the grating plate to exhibit a moving star effect. The first frosted glass is driven by the driving device to rotate. Due to the irregularity of the wrinkle of the surface of the first frosted glass, the cloud effect produced by the first light ray projected onto one surface through the first frosted glass exhibits irregular motion and irregular shape changes, further improving the vividness of simulating the sky effect.
[0011] In addition to changing the motion of the clouds, the movement of the air flow may also cause the clouds to become thinner or thicker, simultaneously the stars may also dim or disappear as the clouds become thicker or may also become brighter as the clouds become thinner or even disappear. Therefore, the projection lamp for simulating a sky effect further comprises a controlling device and a switching device electrically connected with the controlling device, wherein the controlling device controls the first light source to be in an operating state of being normally on or off or a circle of being gradually on or gradually off, and/or controls the second light source to be in an operating state of being normally on or off or a circle of being gradually on or gradually off or flashing, and/or controls the driving device to be in an operating state of operating or stopping, and the switching device switches the operating state of the first light source and/or of the second light source and/or of the driving device through the controlling device. The preferred embodiments can keep the thickness of the clouds substantially constant by controlling the first light source to be normally on, or make the clouds disappear by controlling the first light source to be off, or make the clouds appear sometimes or disappear sometimes or thin sometimes or thick sometimes by controlling the first light source to be in a circle of being gradually on or gradually off. The preferred embodiments can keep the brightness of the stars substantially constant by controlling the second light source to be normally on, or make the stars disappear by controlling the second light source to be off, or make the stars appear sometimes or disappear sometimes or thin sometimes or thick sometimes by controlling the second light source to be in a circle of being gradually on or gradually off, or achieve rapid changes in the brightness of the stars by controlling the second light source to be flashing. The relative motion and relative rest of the clouds and/or stars are achieved by controlling the driving device to operate or stop.
[0012] The projection lamp for simulating a sky effect according to the preferred embodiments may freely switch between different scenes in the following two ways.
[0013] In a first way, the projection lamp comprises a plurality of display modes, each of
2017279839 29 Dec 2017 which is a free combination of the operation states of the first light source, the second light source and the driving device, and switching between the different display modes is enabled by the switching device and the controlling device. In this way, the manufacturer will consider a combination of different states between the first light source, the second light source and the driving device at the beginning of the design, like an automatic mode of a camera, which is convenient for the user and saves the debugging time.
[0014] In a second way, the switching device comprises two or more buttons, each of which separately controls the operation states of the first light source or the second light source or the driving device. The first light source, the second light source and the driving device are equipped with separate buttons, respectively, for debugging the respective states of the respective devices. In this way, the flexibility for use is higher, and the user may match the operating states of the respective devices according to his/her own preference.
[0015] In order to further improve the vividness of a cloud effect, the first light-emitting component further comprises a second frosted glass arranged on the optical path of the light ray emitted by the first light source which is arranged between the first frosted glass and the convex lens or between the first frosted glass and the first light source. The projected cloud is more complicated in texture, diverse in changes when rotated, and more vivid in effect through the superposition and cooperation of the second frosted glass and the first frosted glass. The second frosted glass may be fixedly mounted in the projection lamp or may be rotatably mounted in the projection lamp. If the latter is adopted, the projection lamp preferably rotates relative to the first frosted glass in opposite directions.
[0016] In order to further improve the vividness of a cloud effect, the first light source is provided with a biconvex lens member located on the optical path of the light ray emitted by the first light source, so that the projected cloud is softer and more vivid in effect. Further, the degree of the curvature of the surface of the biconvex lens element facing the first light source is greater than that of the other surface away from the first light source, so that the first light ray emitted from the first light source converges within a short distance and there is a sufficient distance between the biconvex lens element and the convex lens to accommodate the first frosted glass and the second frosted glass.
[0017] Compared with the prior art, the preferred embodiments of the invention have the following beneficial effects:
[0018] 1. A first frosted glass is arranged between the first light source and the convex lens.
The first light ray emitted by the first light source exhibits a cloud effect shaped like cotton on a surface after passing through the first frosted glass and the convex lens so as to achieve the
2017279839 29 Dec 2017 purpose of creating a vivid sky effect indoors.
[0019] 2. The projection lamp further comprises a second light-emitting element. The second light ray exhibits a star-like pattern on a surface through the grating plate so as to exhibit a vivid starry sky indoors and further improve the vividness of the simulation effect.
[0020] 3. The patent also simulates a dynamic changing sky effect through the driving device, so that the projection effect is more natural.
[0021] 4. The combination of the controlling device and the switching device provides the user with more choices of the projection effect.
[0022] Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise”, “comprising”, and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to”.
