DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to enable a person skilled in the art to understand the solutions of the present disclosure better, hereinafter, the technical solutions in the embodiments of the present disclosure will be described clearly and thoroughly with reference to the accompanying drawings of embodiments of the present disclosure. Obviously, the embodiments as described are only some of embodiments of the present disclosure, and are not all the embodiments. On the basis of the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort shall all fall within the scope of protection of the present disclosure.

According to embodiments of the present disclosure, a lamp component is provided. FIG. 1 shows a structural diagram of a lamp component according to embodiments of the present disclosure, and FIG. 2 shows a light propagation diagram in the lamp component. Hereinafter, the lamp component according to embodiments of the present disclosure is described in conjunction with FIG. 1 and FIG. 2.

The lamp component 10 can comprise a reflective layer 101 and a transmissive layer 103.

The reflective layer 101 has a first face 1011 and a second face 1013 opposite the first face 1011. The second face 1013 of the reflective layer 101 may be attached to a predetermined position, for example, the wall, ceiling, etc., of a room.

The reflective layer 101 may be a silver layer or a multilayer film structure, and the reflectivity thereof is greater than 80%. For example, the multilayer film structure may be formed by alternate stacking of two or more materials of a titanium dioxide layer, an indium nitride layer, a zinc sulfide layer, tantalum pentoxide, silicon dioxide, silicon nitride, magnesium fluoride and aluminum oxide according to high and low refractive indexes.

The transmissive layer 103 is provided on the first face 1011 of the reflective layer 101, and the transmissive layer 103 is doped with fluorescent powder particles.

The transmissive layer 103 may be a resin layer, such as silica gel, but the present disclosure is not limited thereto.

In the present disclosure, the fluorescent powder particles in the transmissive layer 103 may comprise at least one of: cerium doped yttrium aluminum garnet (Ce:YAG) or other garnet compositions, red phosphor of Mn4+ doped potassium fluorosilicate (PFS), other Mn4+ doped phosphors having a fluoride host, other Eu2+ doped red nitrides and YAlO3 fluorescent powder particles. For example, if a user expects that the fluorescent powder particles generate yellowish light after being excited, then fluorescent powder particles of cerium doped yttrium aluminum garnet (Ce:YAG) or other garnet compositions may be doped into the transmissive layer 103, and the fluorescent powder particles emit yellowish light after being excited; if the user expects that the fluorescent powder particles generate red light after being excited, then red phosphor of Mn4+ doped potassium fluorosilicate (PFS), other Mn4+ doped phosphors having a fluoride host, other Eu2+ doped red nitride phosphor fluorescent powder particles may be doped into the transmissive layer 103; and if the user expects that the fluorescent powder particles generate green light after being excited, YAlO3 fluorescent powder particles may be doped into the transmissive layer 103. By selecting different fluorescent powder particles excited to generate light of different colors, and selecting different solubility ratios of fluorescent powder particles, excited light and incident light have different ratios, and the finally mixed light effects are different. The doping concentration of the fluorescent powder particles may be dependent on the intensity of desired light.

The fluorescent powder particles doped in the transmissive layer 103 are shown above by way of example, but the present disclosure is not limited thereto. The type and concentration of the fluorescent powder particles doped in the transmissive layer 103 may be adjusted according to the color and intensity of light desired by the user.

In the present disclosure, both the reflective layer 101 and the transmissive layer 103 are flexible.

The lamp component 10 according to embodiments of the present disclosure may further comprise an attachment portion (not shown in FIG. 1), the attachment portion being provided on the second face 1013 of the reflective layer 101 and being used for attaching the lamp component 10 to a predetermined position, such as the ceiling, wall, etc. of a room.

The attachment portion may be: an adhesive coated on the second face 1013 of the reflective layer 101, a magnet provided on the second face 1013 of the reflective layer 101, a hook and loop fastener provided on the second face 1013 of the reflective layer 101, etc., but the present disclosure is not limited thereto; and any component capable of attaching the lamp component 10 to a predetermined position can be provided on the second face 1013 of the reflective layer 101 as the attachment portion.

During use, the lamp component 10 can be attached to a predetermined position, such as the ceiling or wall of a room, by means of the attachment portion provided on the second face 1013 of the reflective layer 101.

When first light 105 emitted from an external directional light source is incident on the lamp component 10 from the transmissive layer 103, a part of the first light 105 interacts with the fluorescent powder particles in the transmissive layer 103 to excite the fluorescent powder particles, to produce second light of a desired color.

For example, the external directional light source may be a light source capable of emitting blue light, for example, a blue laser light source, and the first light 105 may be blue light. However, the present disclosure is not limited thereto, and any high-energy light source capable of exciting the fluorescent powder particles may be the external directional light source, for example, the external directional light source may also use ultraviolet light.

The second light may be yellow light, green light, red light or white light, and the color of the second light may be different according to the type of the fluorescent powder particles.

As shown in FIG. 2, a part of the first light 105 interacting with the fluorescent powder particles in the transmissive layer 103 to excite the fluorescent powder particles to produce second light of a desired color may comprise the following situations:

• • when the first light 105 emitted from the external directional light source is incident on the lamp component 10 from the transmissive layer 103, a first part light 1051 of the first light 105 incident on the transmissive layer 103 directly interacts with the fluorescent powder particles in the transmissive layer 103 to excite the fluorescent powder particles, to produce second light 1071 of a desired color; and/or a second part light 1053 of the first light 105 incident on the transmissive layer 103 transmits through the transmissive layer 103, is incident on the first face 1011 of the reflective layer 101, is reflected by the first face 1011 of the reflective layer 101 and then interacts with the fluorescent powder particles in the transmissive layer 103 to excite the fluorescent powder particles, to produce 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.

As shown in FIG. 2, a third part light 1055 in the first light 105 may first transmit through the transmissive layer 103 and is incident on the first face 1011 of the reflective layer 101, is reflected by the first face 1011 of the reflective layer 101 and then transmits through the transmissive layer 103 in the form of third light 109 without exciting any fluorescent powder particles. The second light 107 generated by exciting the fluorescent powder particles by the first part light and the second part light in the first light 105, and the third light 109 directly transmitted out of the transmissive layer 103 are mixed to form light of a predetermined color, e.g. white light, yellow light, colored light, etc.

In the present embodiment, the lamp component only has a two-layer structure of the reflective layer and the 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.

In addition, the lamp component can be flexibly installed at any position desired by the user in a simple manner, thereby reducing the installation cost of the lamp.

Since the reflective layer and the transmissive layer of the lamp component are flexible, the lamp component can be placed in a bent and folded manner during transportation, which reduces the space occupied by the lamp component and reduces transportation costs.

Furthermore, compared with components such as a back plate and a diffusion plate required by a traditional lamp, the reflective layer and the transmissive layer of the lamp component are cheap, which further reduces the manufacturing costs of the lamp.

In the present embodiment, the lamp component composed of the flexible reflective layer and transmissive layer can be cut into patterns of different shapes by the user according to different uses, so as to produce different effects of illumination, entertainment, etc. under irradiation from the external directional light source. The luminous flux emitted from the lamp component can be greater than 100 lumens.

Here, the predetermined angle may be adjusted appropriately by the user in accordance with the positional relationship between the lamp component 10 and the directional light source 20, as long as light emitted from the directional light source 20 can be incident on a desired part of the lamp component 10.
