Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Example 1
Referring to fig. 1 to fig. 3, the present embodiment provides a deformable light emitting device, including:
a light 10 for providing a light source;
a flexible and transparent casing 20, wherein a deformation cavity 30 is formed between the casing 20 and the light-emitting surface of the light-emitting body 10;
and the photoluminescence body 40 is filled in the deformation cavity 30.
The material of the housing 20 may be thermoplastic polyester elastomer (TPEE) or PDMS, wherein PDMS is polydimethylsiloxane, which is the most widely used organic polymer material based on silicon.
Wherein, the photoluminescence body is a structural body containing photoluminescence materials or directly consists of photoluminescence materials; when the photoluminescence material is a structure containing the photoluminescence material, the photoluminescence material is wrapped by a transparent film. The film may be, for example, a biaxially oriented polypropylene film (BOPP) or a low density polyethylene film (LDPE) or a polyester film (PET).
The photoluminescence material can be fluorescent powder material, long afterglow luminescent material and up-conversion luminescent material. Or a light guiding material as disclosed in the publication of PCT patent publication No. WO 2012/127389 a1, wherein the light guiding material comprises a carrier material with a photoluminescent material.
In this embodiment, the light emitter 10 is diversified, and the selection of the light emitter 10 may be diversified: for example, the type of illuminant 10 can be an LED light source, an OLED light source, an optical fiber, a quantum dot light source, a miniLED light source; the luminous body 10 may be composed of a single light source, or may be composed of two or more light sources; the luminous body may be composed of one type of light source, and may also be composed of a plurality of types of light sources.
Accordingly, the combined arrangement of the luminaire 10 and the housing 20 can be diversified: for example, as shown in fig. 1, if the light-emitting body 10 is a single optical fiber, the light-emitting surface is the outer peripheral surface thereof, and correspondingly, the housing is also circular and wraps the light-emitting body 10. In a natural state, the light emitting device forms a small cylindrical light emitting surface, and after the deformation cavity 30 expands, as shown in fig. 2, the distribution density of the photoluminescent bodies 40 in the deformation cavity becomes small, and light of the light source absorbed by the photoluminescent bodies is emitted from the housing 20, so that the light emitting area of the light emitting device is enlarged.
As shown in fig. 3, the light 10 is at least one light source 12 mounted on one side of the mounting plate 11; the light source may be an LED light source, an OLED light source, an optical fiber, a quantum dot light source, a miniLED light source, or an OLED light source with a single light emitting body, and the light emitting surface is the upper surface of the light emitting body in the direction of the figure, and accordingly, the housing 20 is a sheet with edges extending downward to form a connecting portion. After the deformation cavity 30 is expanded, as shown in fig. 4, the distribution density of the photoluminescent bodies 40 in the deformation cavity is reduced, the light absorbed by the photoluminescent bodies is emitted from the outer wall of the housing 20, and the shape of the light-emitting device is changed from a natural single-side light-emitting shape to an arc-shaped light-emitting surface.
As shown in fig. 5, the light-emitting body is at least one of an LED light source, an OLED light source, an optical fiber, a quantum dot light source, and a miniLED light source, which are mounted on two sides of the mounting board, and the light-emitting surfaces thereof are the upper surface and the left side surface in the drawing direction, and accordingly, the housing 20 is a sheet shape with a connecting portion extending from the edge thereof. After the deformation cavity 30 is expanded, as shown in fig. 6, the distribution density of the photoluminescent bodies 40 in the deformation cavity 30 is reduced, and the light absorbed by the photoluminescent bodies is emitted from the outer wall of the housing 20, so that the light emitting area of the light emitting device is enlarged.
The above examples are only some examples of the combination of the housing and the light emitter according to the present invention, and the present invention is not limited to the above examples.
In the above example, the default is to configure the light-emitting device with an inflation pump for deformation power; the deformation cavity is provided with an inflation inlet connected with the air pump.
In other applications, the deformation of the deformation chamber may be caused by external force applied to the housing 20, for example, when the light-emitting device shown in fig. 1 is used for night indication, it may be clamped in the gap of the mounting frame 100, and the housing is clamped by the mounting frame 100 to form a flat shape as shown in fig. 7, so as to change its light-emitting shape, such that it has a larger light-emitting area on two sides.
In the present embodiment, the light emitting device is provided with a power supply for supplying power to the light source on the light emitting body 10, such as a battery or a power conversion module for connecting an external power supply. The power supply or the power supply conversion module is arranged at one end of the light-emitting device.
Example 2
On the basis of embodiment 1, the photoluminescent body 40 provided in this embodiment is formed by wrapping a photoluminescent material 42 with a transparent film 41, and the photoluminescent body 40 is filled with a light gas 43.
As shown in fig. 8, the photoluminescent emitter 40 is formed with a first cavity 44 and a second cavity 45, where the first cavity 44 is used for filling the photoluminescent material 42, and the second cavity 45 is used for filling a light gas, such as hydrogen.
Wherein, the mode of setting up of first cavity and second cavity is optional to have:
1. as shown in fig. 8, the first cavity 44 may be arranged in line with the second cavity 45;
2. the first cavity 44 and the second cavity 45 may also be arranged in a surrounding manner: the first cavity 44 surrounds the outside of the second cavity 45 as shown in fig. 9, or the second cavity 45 surrounds the outside of the first cavity 44 as shown in fig. 10;
3. the first cavity 44 and the second cavity 45 are integrated to form a cavity in which the photoluminescent material and the light gas are mixed.
This embodiment makes photoluminescence body suspension in the deformation intracavity, and then makes the luminous more even of whole illuminator in each direction.
Example 3
On the basis of the embodiment 1, as shown in fig. 11, a metal sheet 46 is attached to a surface of a part of the photoluminescence body 40; the side wall of the shell 20 is uniformly provided with magnetic sheets 22. In other embodiments, a metal sheet 46 may be attached to the surface of all of the photo-emitters 40.
In this embodiment, the design of the photoluminescent bodies 40 and the magnetic sheets and the metal sheets 46 of the housing 20 allows the photoluminescent bodies 40 to be still fully distributed on the surface of the housing 20 when the deformation cavity is enlarged, so that the distribution of the photoluminescent bodies 40 in the deformation cavity is uniformly distributed along with the change of the deformation cavity, and the whole light emitting device emits light more uniformly in all directions in various states.
Example 4
