Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of lighting fixtures. Specifically, the present disclosure relates to lighting fixture components and lighting fixture devices. Background Art
[0002] Different lighting fixtures have different shape structures. When manufacturing lighting fixtures, different molds need to be prepared to adapt to different shape structures of lighting fixtures. Moreover, a lighting fixture includes multiple components such as a back plate and a diffuser plate, which results in a very high manufacturing cost of lighting fixtures. In addition, since large-sized lighting fixtures (e.g., ceiling lights) have high brightness and low glare, users are increasingly fond of large-sized lighting fixtures. However, the increase in the size of lighting fixtures will inevitably lead to a further increase in their manufacturing cost and transportation cost.
[0003] In addition, due to the diversity and complexity of the structure of lighting fixtures, when installing lighting fixtures, professional personnel are required to operate, which also results in a very high labor cost for installing lighting fixtures.

[0080] To enable those skilled in the art to better understand the present disclosure solution, the following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.
[0081] According to an embodiment of the present disclosure, a lamp component is provided. Figure 1 The structural diagram of the lamp component according to an embodiment of the present disclosure is shown, Figure 2 The light propagation diagram in the lamp component is shown. The following will be combined with Figure 1 and Figure 2 to describe the lamp component according to an embodiment of the present disclosure.
[0082] The lamp component 10 may include a reflective layer 101 and a transmissive layer 103.
[0083] The reflective layer 101 has a first surface 1011 and a second surface 1013 opposite to the first surface 1011. The second surface 1013 of the reflective layer 101 may be attached to a predetermined position, for example, the wall or ceiling of a room.
[0084] The reflective layer 101 may be a silver layer or a multilayer film structure with a reflectivity greater than 80%. For example, the multilayer film structure may be composed of two or more materials such as titanium dioxide layer, indium nitride layer, zinc sulfide layer, tantalum pentoxide, silicon dioxide, silicon nitride, magnesium fluoride, and aluminum oxide stacked alternately according to high and low refractive indices.
[0085] The transmissive layer 103 is disposed on the first surface 1011 of the reflective layer 101, and phosphor particles are doped in the transmissive layer 103.
[0086] The transmissive layer 103 may be a resin layer, such as silica gel, etc., but the present disclosure is not limited thereto.
[0087] In the present disclosure, the phosphor particles in the transmissive layer 103 may include cerium-doped yttrium aluminum garnet (Ce:YAG) or other garnet compositions, Mn 4+ doped potassium fluorosilicate (PFS) red phosphor, other Mn 4 + doped phosphors, other Eu 2+At least one of doped red nitrides and YAlO3 phosphor particles. For example, if a user desires yellowish light to be generated after the phosphor particles are excited, cerium-doped yttrium aluminum garnet (Ce:YAG) or other garnet composition phosphor particles that emit yellowish light after excitation can be doped into the transmissive layer 103; if a user desires red light to be generated after the phosphor particles are excited, Mn can be doped into the transmissive layer 103 4+ Red phosphors of doped potassium fluorosilicate (PFS), other Mn with a fluoride host 4+ Doped phosphors, other Eu 2+ Doped red nitride phosphor particles; if a user desires green light to be generated after the phosphor particles are excited, YAlO3 phosphor particles can be doped into the transmissive layer 103. By selecting different phosphor particles, different colors of light can be excited, and different solubility ratios of the phosphor particles result in different ratios of the excited light to the incident light, ultimately resulting in different light mixing effects. The doping concentration of the phosphor particles can be determined according to the desired intensity of the light.
[0088] The above shows, by way of example, the phosphor particles doped in the transmissive layer 103, but the present disclosure is not limited thereto, and the type and concentration of the phosphor particles doped in the transmissive layer 103 can be adjusted according to the color and intensity of the light desired by the user.
[0089] In the present disclosure, both the reflective layer 101 and the transmissive layer 103 are flexible.
[0090] The lamp component 10 according to an embodiment of the present disclosure may further include an attachment portion (not shown in Figure 1 ) that is provided on the second surface 1013 of the reflective layer 101 and is used to attach the lamp component 10 to a predetermined position, such as the ceiling, wall, etc. of a room.
[0091] The attachment portion may be an adhesive coated on the second surface 1013 of the reflective layer 101, a magnet provided on the second surface 1013 of the reflective layer 101, a hook-and-loop fastener provided on the second surface 1013 of the reflective layer 101, etc., but the present disclosure is not limited thereto, and any component that can attach the lamp component 10 to a predetermined position can be used as the attachment portion and provided on the second surface 1013 of the reflective layer 101.
[0092] In use, the lamp component 10 can be attached to a predetermined position, such as the ceiling or wall of a room, through the attachment portion provided on the second surface 1013 of the reflective layer 101.
[0093] When the first light 105 emitted from an externally directed light source is incident on the lamp component 10 from the transmissive layer 103, a part of the first light 105 interacts with the phosphor particles in the transmissive layer 103 to excite the phosphor particles to generate the second light of a desired color.
[0094] For example, the externally directed light source can be a light source capable of emitting blue light, such as a blue laser light source, and the first light 105 can be blue light. However, the present disclosure is not limited thereto, and any high-energy light source capable of exciting the phosphor particles can be the externally directed light source. For example, ultraviolet light can also be used as the externally directed light source.
[0095] The second light can be yellow light, green light, red light, or white light, and the color of the second light can vary according to the type of the phosphor particles.
[0096] As Figure 2 shown, the situation where a part of the first light 105 interacts with the phosphor particles in the transmissive layer 103 to excite the phosphor particles to generate the second light of a desired color can include the following cases.
[0097] When the first light 105 emitted from an externally directed light source is incident on the lamp component 10 from the transmissive layer 103, the first partial light 1051 of the first light 105 incident on the transmissive layer 103 directly interacts with the phosphor particles in the transmissive layer 103 to excite the phosphor particles to generate the second light 1071 of a desired color; and / or the second partial light 1053 of the first light 105 incident on the transmissive layer 103 transmits through the transmissive layer 103, is incident on the first surface 1011 of the reflective layer 101, and after being reflected by the first surface 1011 of the reflective layer 101, interacts with the phosphor particles in the transmissive layer 103 to excite the phosphor particles to generate the second light 1073 of a desired color. Hereinafter, when there is no need to distinguish the second light, the second light 1071 and the second light 1073 are collectively referred to as 107.
[0098] As Figure 2 shown, the third partial light 1055 of the first light 105 may first transmit through the transmissive layer 103 and be incident on the first surface 1011 of the reflective layer 101. After being reflected by the first surface 1011 of the reflective layer 101, it transmits through the transmissive layer 103 in the form of the third light 109 without exciting any phosphor particles. The mixture of the second light 107 generated by exciting the phosphor particles with the first partial light and the second partial light of the first light 105 and the third light 109 directly transmitting out of the transmissive layer 103 can form light of a predetermined color, such as white light, yellow light, colored light, etc.
[0099] In this embodiment, the lamp component only has a two-layer structure including a reflective layer and a transmissive layer, which greatly simplifies the structure of the lamp, reduces the manufacturing cost of the lamp, and can achieve good light brightness and low glare.
[0100] In addition, the lamp components can be flexibly installed at any position desired by the user in a simple manner, reducing the installation cost of the lamp.
[0101] Since the reflective layer and the transmissive layer of the lamp components are flexible, during transportation, the lamp components can be placed in a curled and folded manner, which reduces the occupied space of the lamp components and lowers the transportation cost.
[0102] Moreover, compared with components such as the backplane and diffuser plate required by traditional lamps, the reflective layer and the transmissive layer of the lamp components are inexpensive, which further reduces the manufacturing cost of the lamp.
[0103] In this embodiment, the lamp component composed of the flexible reflective layer and transmissive layer can be cut into different shape patterns by the user according to different uses to produce different lighting, entertainment and other effects under the illumination of light from an external directional light source. The luminous flux emitted from the lamp component can be greater than 100 lumens.
[0104] According to another embodiment of the present disclosure, a lamp device is provided. Figure 3 The structural diagram of the lamp device according to the embodiment of the present disclosure is shown. Figure 4 One installation method of the lamp device according to the embodiment of the present disclosure is shown. The following will be combined with Figures 3 to 4 to describe the lamp device according to another embodiment of the present disclosure.
[0105] As Figure 3 shown, the lamp device 1 according to another embodiment of the present disclosure includes a lamp component 10 and a directional light source 20.
[0106] The lamp component 10 includes: a reflective layer having a first surface and a second surface opposite to the first surface and capable of being attached to a predetermined position; and a transmissive layer provided on the first surface of the reflective layer, and phosphor particles are doped in the transmissive layer.
[0107] It should be noted here that the specific structure of the lamp component 10 in the lamp device 1 is exactly the same as the structure described in combination with Figure 1 and Figure 2 To avoid over-description making the present disclosure obscure and difficult to understand, the specific structure of the lamp component 10 in the lamp device 1 will not be described in detail here. The description of the lamp component 10 in the following description can be understood with reference to the above description.
[0108] The directional light source 20 is configured to be able to emit first light 105 at a predetermined angle to the transmissive layer 103 of the lamp component 10. When the first light 105 is incident on the lamp component 10 from the transmissive layer 103, a part of the first light 105 interacts with the phosphor particles in the transmissive layer 103 to excite the phosphor particles to generate second light of a desired color. Here, the predetermined angle can be appropriately adjusted by the user according to the positional relationship between the lamp component 10 and the directional light source 20, as long as the light emitted from the directional light source 20 can be incident on the desired part of the lamp component 10.
[0109] The directional light source 20 can be a light source capable of emitting blue light. For example, a blue laser light source, and the first light 105 can be blue light. However, the present disclosure is not limited thereto, and any high-energy light source capable of exciting phosphor particles can be an external directional light source. For example, ultraviolet light can also be used as the directional light source.
[0110] The second light can be yellow light, green light, red light, or white light, and the color of the second light can be different according to the type of phosphor particles.
[0111] Combined Figure 2 , a part of the first light 105 emitted from the directional light source 20 interacts with the phosphor particles in the transmissive layer 103 to excite the phosphor particles to generate second light of a desired color, which can include the following situations.
[0112] When the first light 105 emitted from the directional light source 20 is incident on the lamp component 10 from the transmissive layer 103, the first part of the first light 1051 incident on the transmissive layer 103 directly interacts with the phosphor particles in the transmissive layer 103 to excite the phosphor particles to generate the second light 1071 of a desired color; and / or the second part of the first light 1053 incident on the transmissive layer 103 transmits through the transmissive layer 103, is incident on the first surface 1011 of the reflective layer 101, and after being reflected by the first surface 1011 of the reflective layer 101, interacts with the phosphor particles in the transmissive layer 103 to excite the phosphor particles to generate the second light 1073 of a desired color.
[0113] As Figure 2 shown, the third part of the first light 1055 emitted from the directional light source 20 may first transmit through the transmissive layer 103 and be incident on the first surface 1011 of the reflective layer 101. After being reflected by the first surface 1011 of the reflective layer 101, it transmits through the transmissive layer 103 in the form of the third light 109 without exciting any phosphor particles. The second light 107 generated by exciting the phosphor particles by the first part and the second part of the first light 105 and the third light 109 directly transmitted through the transmissive layer 103 can be mixed to form light of a predetermined color, such as white light, yellow light, colored light, etc.
[0114] As Figure 4As shown, when installed, the luminaire component 10 can be attached to the ceiling of a room through an attachment portion, and the directional light source 20 can be located on the side wall of the room or on the floor directly below where the luminaire component 10 is located in the room.
[0115] The above describes a luminaire device in which the luminaire component and the directional light source are separately provided according to an embodiment of the present disclosure. However, the present disclosure is not limited thereto, and various deformations can be made to the luminaire device 1 according to an embodiment of the present disclosure.

[0119] The support plate 30 is disposed at the first end 2011 of the first support rod 201 and is perpendicular to the first support rod 201. The support plate 30 has a first surface 301 facing the second support rod 203 and a second surface 303 opposite to the first surface 301.

[0121] The directional light source 20 can be offset from the luminaire component 10 by a predetermined distance in the horizontal direction or be located directly below the luminaire component 10.

As Figure 6 shown, the luminaire device 1 according to the second modification example may further include a connecting portion 40 for connecting the luminaire component 10 and the directional light source 20.

[0130] According to the above variants of the lamp device, the lamp device according to an embodiment of the present disclosure can also be summarized as follows.
[0131] A lighting device has a flexible reflective light-emitting part and a light source part away from the flexible reflective light-emitting part. The reflective light-emitting part and the light source part are connected by a connecting part. The flexible reflective light-emitting part has a reflective layer and a transmissive layer, and a fluorescence excitation substance is provided in the transmissive layer. When the first light emitted from the light source part irradiates the flexible reflective light-emitting part, the fluorescence excitation substance is excited by the first light to generate the second light, and the first light and the second light are mixed and then emit light of a predetermined color outward.
[0132] Although the lighting components are shown in circular and rectangular shapes in the drawings, the present disclosure is not limited thereto, and the lighting components may have various shapes according to user requirements.
[0133] The lighting device according to an embodiment of the present disclosure provides a lighting device with a simple structure and low manufacturing cost. Since the flexible reflective light-emitting part has a reflective layer and a transmissive layer doped with phosphor particles, good light brightness and low glare can be achieved by irradiating the transmissive layer through the light source part. During transportation, the flexible reflective light-emitting part can be curled and folded for placement, reducing the occupied space of the lighting device and lowering the transportation cost.
[0134] In the above embodiments of the present disclosure, the descriptions of the respective embodiments have their own focuses. For the parts not detailed in a certain embodiment, reference may be made to the relevant descriptions of other embodiments.
[0135] The above are only the preferred embodiments of the present disclosure. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present disclosure, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present disclosure.
