Description

Luminaire device with sign luminous display effect

The new model relates to a lamp for an automobile, in particular to a lamp device with the luminous display effect of a logo such as a trademark.

A trademark is an identifying mark used to indicate the source of goods or services. When consumers buy products marked with specific trademarks, in addition to representing trust in the goodwill of the trademark owner, they can also ensure that the purchased products have a certain quality. Even when the goodwill of the trademark owner or the quality of the products it manufactures reaches a certain level, the trademark on the product becomes the recognition of the consumer's image and identity. This is especially the case in the automotive industry.

At present, there are roughly two ways to make trademarks illuminate in the automobile industry. One is to surround the outline of the trademark with light guide strips, so that when the light guide strips emit light, the light directly projected to the observer through the light guide strips outlines the trademark. The second is to hollow out the shading plate to the shape of the trademark, and set a light source behind the shading plate. When the light source projects the light to the shading plate and the observer, the light passing through the shading plate is not blocked by the shading plate, and the light passing through the shading plate is not blocked. A logo outline can be formed in the eyes of the observer. Although the above two methods can highlight trademarks, most of them can only be used as decorative lights, or at most as warning lights, and they do not have other functions and need to be further improved.

The purpose of the present invention is to provide a lighting device with a luminous display effect of a sign that can overcome at least one disadvantage of the prior art.

The luminaire device with the effect of illuminating and displaying signs includes a light guide plate, a light guide strip, a cover layer, and a light emitting unit.

The light guide plate includes a first board surface and a second board surface opposite to each other, and a first board edge and a second board edge connected between the first board surface and the second board surface and opposite to each other. The connecting line from the first edge to the second edge defines a light traveling direction. A light emitting structure extending along the second board edge is formed on the second board edge. The light guide strip is arranged on the edge of the first board and forms a light guide structure. The covering layer covers one of the first board surface and the second board surface, and defines a hollow area around it. The cover layer cooperates with the light guide plate to define a boundary that outlines the outline of the hollow area. The light emitting unit can provide light traveling along the light guide strip and guided into the light guide plate from the edge of the first board by the light guide structure of the light guide strip. A part of the light travels in the light guide plate along the light travel direction, and is emitted from the light emitting structure along the light travel direction. Another part of the light ray exits through the junction in a direction transverse to the direction of travel of the light ray.

The effect of the new type is that the light emitted from the light emitting structure along the traveling direction of the light can be used to warn or indicate the traveling direction of the vehicle, and the light emitted through the junction in a way that crosses the traveling direction of the light can outline the wheel out of the hollow area outline, resulting in the effect of the edge of the logo glowing.

A light guide structure 23 is formed on the outer surface 22 . The light guide structure 23 has a sawtooth shape concave toward the inner surface 21 , so that after the light is properly reflected in the light guide 2 for a certain number of times, it can exit the inner surface 21 of the light guide 2 and pass through the light guide 2 . The light incident structure 13 of the light guide plate 1 enters the light guide plate 1 .

Referring to FIGS. 2 , 3 and 4 , the cover layer 3 is light-transmitting blue, and covers the rear of the second plate surface 112 , and defines a hollow area 31 , which is in line with the light guide plate 1 . A boundary 32 that outlines the outline of the hollow area 31 is defined in cooperation. The hollow area 31 can be, for example, the character of TYC, but in other embodiments of the present invention, it can also be a logo of other characters, designs, or an identifiable trademark.

The light-emitting unit 4 is arranged on the top of the light guide plate 1 and is connected to the light guide bar 2 . The light-emitting unit 4 includes a heat sink 41 for heat dissipation, a circuit board 42 for power control, and an LED chip (not shown in the figure) for providing light. Since the structure of the light-emitting unit 4 is common knowledge, the detailed description is omitted here.

During the operation of this embodiment, the light of the light-emitting unit 4 will travel along the light guide bar 2 , and under the action of the light guide structure 23 of the light guide bar 2 , from right to left from the first board edge 121 The formed light incident structure 13 enters the light guide plate 1 .

The main part of the ray will travel along the ray travel direction D1 in the guide The light travels in the light plate 1 and is emitted from the light exit structure 14 formed by the second plate edge 122 along the light travel direction D1. Since the light of the light-emitting unit 4 is mainly emitted from the light-emitting structure 14 along the light traveling direction D1, and the light intensity is sufficient, the part of the light emitted from the light-emitting structure 14 can not only be used as a warning light or an indicator light, but also It can meet the requirements of regulations and be used as a direction light.

Since the refractive index of the cover layer 3 and the light guide plate 1 is different, the other part of the light, when passing through the boundary 32 formed by the cover layer 3 and the light guide plate 1, will be able to cross the The light is emitted in the direction of the traveling direction D1 (for example, the front-rear direction) to form a light edge that outlines the outline of the hollowed-out region 31 , so that the hollowed-out region 31 is formed suddenly.

The other part of the light can be emitted through the cover layer 3 along the direction transverse to the light travel direction D1 (for example, the front-to-back direction) to form a heart-shaped light area, and also because the cover layer 3 and the light guide plate The refractive index of 1 is different, and an illumination area corresponding to the hollow area 31 also exists in the heart-shaped light area. Therefore, this embodiment can provide two different logo display effects, which is quite special.

In the present invention, the front and rear directions are not absolute, but are only used to illustrate with the drawings for the reader's understanding.
