Detailed Description

Referring to fig. 1 to 3, the embodiment of the lighting device of the present invention comprises a transparent light guide plate 1 with a heart-shaped appearance, a transparent light guide strip 2 on one side of the light guide plate 1, a covering layer 3 covering one side of the light guide plate 1, and a light emitting unit 4 connecting the light guide plate 1 and the light guide strip 2.

The light guide plate 1 includes a first plate surface 111 located in front and a second plate surface 112 located in rear, which are opposite in front and rear, and a first plate edge 121 (located on the right side) and a second plate edge 122 (located on the left side) which are connected between the first plate surface 111 and the second plate surface 112 and located on the left and right opposite sides.

The first plate edge 121 defines a light traveling direction D1 toward the second plate edge 122. The light traveling direction D1 can be right left or substantially right left, that is, can be obliquely advanced slightly away from right left or right. Specifically, the light traveling direction D1 of the present embodiment is slightly inclined from the upper right to the lower left in the drawing planes of fig. 2 and 3, and deviates from the positive left-right direction by about 2 degrees. The first plate edge 121 is formed with a light incident structure 13 that extends along the first plate edge 121 in a bending manner and is concave from right to left. The light incident structure 13 is stepped, so that light rays enter the light guide plate 1 from the light guide strip 2 and travel along the light ray traveling direction D1, and includes a plurality of vertically extending first light incident surfaces 131 and a plurality of horizontally extending second light incident surfaces 132 which are vertically and alternately connected with each other.

The second plate edge 122 is formed with a light exit structure 14 which is stepped, extends along the second plate edge 122 in a bending manner, and is concave from left to right. The central main portion of the light exiting structure 14 is left-right symmetrical to the central main portion of the light entering structure 13 (which is slightly asymmetrical in fig. 3 due to the broken line), and includes a plurality of first light exiting surfaces 141 extending up and down and a plurality of second light exiting surfaces 142 extending left and right, which are alternately connected to each other vertically. Each of the first light emitting surfaces 141 is parallel to the respective first light incident surface 131, and each of the second light emitting surfaces 142 is parallel to the respective second light incident surface 132. In practice, based on processing limitation or other factors, a portion of the first light emitting surface 141 is not parallel to the first light incident surface 131, and a portion of the second light emitting surface 142 is not parallel to the second light incident surface 132.

The light guide strip 2 is disposed at the right side of the first plate edge 121 and includes an inner strip surface 21 facing the first plate edge 121 and an outer strip surface 22 opposite to the inner strip surface 21. The outer strip face 22 is formed with a light guiding structure 23. The light guide structure 23 is a sawtooth shape extending toward the inner strip surface 21, and is configured to enable light to be properly reflected in the light guide strip 2 for a certain number of times, and then the light can be emitted from the inner strip surface 21 of the light guide strip 2 and enter the light guide plate 1 through the light incident structure 13 of the light guide plate 1.

Referring to fig. 2, 3 and 4, the covering layer 3 is light-transmissive blue, covers the rear portion of the second plate surface 112, and surrounds to define a hollow area 31, and cooperates with the light guide plate 1 to define a boundary 32 outlining the hollow area 31. The fretwork district 31 is the typeface of "TYC" in this embodiment, nevertheless is in the utility model discloses an in other implementation form appearance, also can be the sign of other typefaces, patterns, or have the trade mark of discernment nature.

The light emitting unit 4 is arranged at the top end of the light guide plate 1 and connected with the light guide strip 2. The light emitting unit 4 includes a heat sink 41 for heat dissipation, a circuit board 42 for controlling power supply, and an LED chip (not shown) for supplying light. Since the junction structure of the light emitting unit 4 is common knowledge, a detailed description thereof will be omitted.

In the present embodiment, the light emitted from the light emitting unit 4 travels along the light guiding strip 2, and enters the light guide plate 1 from the light incident structure 13 formed by the first plate edge 121 from right to left under the action of the light guiding structure 23 of the light guiding strip 2.

A major portion of the light travels in the light guide plate 1 along the light traveling direction D1, and is emitted from the light emitting structure 14 formed on the second plate edge 122 along the light traveling direction D1. Since the light emitted from the light emitting unit 4 mainly exits from the light emitting structure 14 along the light traveling direction D1, the light intensity is sufficient, and thus, the light emitted from the light emitting structure 14 can be used as a direction indicator, besides a warning light or an indicator, and can meet the requirements of regulations.

Since the refractive indexes of the cover layer 3 and the light guide plate 1 are different, other portions of the light ray can be emitted along a direction (for example, a front-back direction) intersecting the light ray advancing direction D1 when passing through the boundary 32 formed by the cover layer 3 and the light guide plate 1, so that a light edge outlining the shape of the hollow area 31 is formed, and the mark corresponding to the hollow area 31 is formed suddenly.

Other portions of the light can be emitted through the cover layer 3 along a direction (e.g., a front-back direction) transverse to the light traveling direction D1 to form a heart-shaped light region, and since the cover layer 3 and the light guide plate 1 have different refractive indexes, a logo illumination region in a shape of "TYC" corresponding to the hollow area 31 also exists in the heart-shaped light region. Therefore, the embodiment can provide two different display effects of the logo, and is quite special.

In the present invention, the front-back direction is not absolute, but only used for illustration with accompanying drawings for the reader to understand. In other embodiments of the present invention, the covering layer 3 may be disposed on the first board 111 and the second board 112, or the covering layer 3 may be disposed on the first board 111, and the present embodiment is not limited thereto.

To sum up, the utility model discloses the efficiency of lamps and lanterns device lies in: the light emitted from the light emitting structure 14 along the light traveling direction D1 can provide the effect of a warning light, an indicator light or a direction light, and the light emitted from the boundary 32 in a manner transverse to the light traveling direction D1 can outline the hollow area 31 to generate the effect of light emission of the identification light edge. Preferably, after the light emitted transversely to the light traveling direction D1 is emitted through the cover layer 3, a light area having a logo illuminating area can be formed, and another different logo displaying effect is further provided. In addition, the cover layer 3 can also use a special identification color of a company or a trademark, so that a heart-shaped light area formed by the cover layer 3 has a specific color, and the identification effect is enhanced.

The above-mentioned embodiments are only examples of the present invention, and the scope of the present invention should not be limited thereby, and the scope of the present invention should be covered by the claims and the description of the invention.
