Description

Glowing frame

The present invention relates to a light-emitting frame.

The conventional illuminated frame has two ways of making it. One is a direct-lit light-emitting frame, and the other is a side-in type light-emitting frame. The light emitting frame includes a light source and a light guiding strip. The direct-lit light-emitting frame is provided with a point source or a line source below the light guiding strip. If a point source is used, in order to make the light uniform, the point source needs to have sufficient distance and diffuser. In this way, the light-emitting frame needs to retain sufficient space depth to accommodate the light-guiding strip and the point light source, which is not easy to construct, and is inconvenient for the designer. If a line source is used, the thickness and power consumption of the line source are greater than the point source, which is still disadvantageously thin and energy-saving.

The side-in type of light-emitting frame is provided with a point light source on the side of the light guiding strip. The point light source may be disposed on a side of the short axis of the parallel light guiding strip or a side of the long axis of the parallel light guiding strip. When the point source is disposed on the side of the parallel short axis, the light is limited by the distance, and it is difficult to transmit from one end of the light guiding strip to the other end, so that the light of the light guiding strip cannot be evenly distributed. When the point source is placed on the side of the parallel long axis, although the uniformity of light is provided, a large amount of light energy is wasted.

One aspect of the present invention is a light-emitting frame.

According to an embodiment of the invention, a light-emitting frame includes a frame body, a light bar and a light guiding strip. The light bar is located in the frame body. The light bar has a plurality of light sources. The light guiding strip has opposing first and second surfaces, and a third surface adjacent to the first surface and the second surface. The light guiding strip includes a transition zone and a light emitting zone. The transition zone is obscured by the frame body. The first surface of the light guiding strip is located in the transition zone and includes a plurality of curved surfaces and a plurality of light incident surfaces. The light incident surfaces are respectively adjacent to the curved surface, and the light incident surfaces are respectively directed toward the light source. The illuminating zone is adjacent to the transition zone. The third surface of the light guiding strip is at least partially located in the light emitting area, and is exposed from the frame body at the third surface of the light emitting area.

In an embodiment of the invention, the light incident surface is perpendicular to the longitudinal direction of the light guiding strip.

In an embodiment of the invention, the transition zone has a plurality of grooves, and the grooves are respectively located between the curved surface and the light incident surface.

In an embodiment of the invention, the light sources are respectively located in the grooves.

In an embodiment of the invention, the light guiding strip further includes a plurality of light guiding patterns, and the light guiding pattern is distributed on the third surface of the light guiding strip.

In an embodiment of the invention, the density of the light guiding pattern is gradually increased from a position at a center of the third surface corresponding curved surface to a position at an end portion of the third surface corresponding curved surface.

In an embodiment of the invention, the light guiding strip has a fourth surface opposite to the third surface. The light guiding strip further comprises a plurality of light guiding patterns. The light guiding pattern is distributed on the fourth surface of the light guiding strip.

In one embodiment of the present invention, the density of the light guiding pattern is gradually increased from a position at a center of the fourth surface corresponding curved surface to a position at an end portion of the fourth surface corresponding curved surface.

In an embodiment of the invention, the frame body surrounds the accommodating space, and the light guiding strip is located at one side of the accommodating space.

In the above embodiment of the present invention, the light bar is located in the frame body, and the transition region of the light guiding strip is shielded by the frame body and exposed from the frame body at the third surface of the light emitting region. When the light source of the light guiding strip emits light, the light of the light source can enter from the light incident surface of the first surface of the light guiding strip, and is reflected by the curved surface of the first surface to emit light from the third surface of the light guiding strip. With such a design, the user only sees the light on the third surface of the light-emitting area of the light guide strip, and does not see the light of the light source and the light guide strip transition area blocked by the frame body. In this way, not only the light uniformity of the light-emitting frame can be improved, but also the space for setting the light bar and the light guide strip can be saved. In addition, since the first surface has a curved surface to reflect light, the light-emitting frame can have sufficient brightness by providing a small amount of light source, thereby achieving energy saving effect.
