Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a luminous curtain device, and more particularly to a luminous curtain device that is applied on a sunroof sunshade, a side window sunshade, a rear glass sunshade, and a rear space sunshade of an automobile, and has a luminous effect.

2. Description of Related Art

To avoid sunlight directly projecting into an interior of an automobile, or to shade a rear space of the automobile, various types of conventional curtain devices applied on a sunroof sunshade, a side window sunshade, a rear glass sunshade, and the rear space sunshade of the automobile are provided for users.

The conventional curtain device is provided with a dark curtain to shade the sunlight or the rear space of the automobile. The dark curtain is made of a soft object, such as a fabric, such that the dark curtain can be operated to be expanded or wounded. However, the dark curtain only has a single function, which is to shade the sunlight. In addition, in the conventional art, research and development of the curtain device is focused on shading the sunlight. Besides, in terms of figures and patterns, the dark curtain is mostly plain and provides very basic decoration. Therefore, the conventional curtain devices are highly monotonous and have little distinction and differentiation from one another. To increase competitiveness of curtain devices and highlight diversities, the conventional curtain devices need to be improved.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a luminous curtain device to resolve the problems of the conventional curtain device.

The luminous curtain device has a luminous curtain, a side member, and a luminous module.

The luminous curtain is implemented as a fabric and comprises multiple optical fibers, a first end, and a second end opposite the first end, wherein the optical fibers extend toward the first end.

The side member is elongated, and comprises a clamping portion and a mounting space. The clamping portion is located on a long side of the side member, and comprises a clamping slit formed and extending in the clamping portion, wherein the first end is inserted into the clamping slit. The mounting space is formed in the side member and communicates with the clamping slit, and ends of the optical fibers of the luminous curtain face toward the mounting space.

The luminous module is mounted in the mounting space of the side member, and comprises a luminous part facing toward the ends of the optical fibers of the luminous curtain.

Other objectives, advantages and novel features of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The luminous module 40a may be implemented as a light emitting diode light bar that can emit monochromatic light or polychromatic light. When the luminous module 40a emits polychromatic light, the luminous module 40a can be controlled to select a color mode of the light to generate lighting variations. The luminous module 40a is mounted in the mounting space 33a of the side member 30a. A luminous part of the luminous module 40a faces toward the ends of the optical fibers 201a of the luminous curtain 20a to project light on the optical fibers 201a. Preferably, the luminous module 40a is implemented as the light emitting diode light bar mounted in and positioned in the embedding recess 36a of the side body 34a of the side member 30a. The luminous module 40a may be electrically connected with an external power supply.

In addition, the luminous module 40 mounted in the side member 30 can directly project light on the ends of the optical fibers 201a of the luminous curtain 20, as shown in FIG. 3. Alternatively, light emitted by the luminous module 40a can be transmitted by the light-guiding plate 41a to indirectly project on the ends of the optical fibers 201a of the luminous curtain 20a, as shown in FIG. 6. Then, the light can be transmitted or diffused by the optical fibers 201a to make the luminous curtain 20, 20a passively luminous. Therefore, the luminous curtain device 10, 10a can provide soft lighting to an interior of the automobile for decoration.

From the above description, it is noted that the present invention has the following advantages:

1. The luminous curtain device 10, 10a can be applied on the sunroof sunshade, the side window sunshade, the rear glass sunshade, and the rear space sunshade of the automobile.
