Problems solved by technology

[0005] The present invention solves the problem that the prior art shading cover exposes the light guide plate outside the light-emitting surface, and the light guide plate has a frame, which reduces the light-emitting surface and affects the appearance, and the structure of the light guide plate and the light hood is arranged so that splicing is relatively difficult, and it is impossible to perform arbitrary splicing during splicing. The technical problem of seamless splicing provides a light guide plate and lighting fixture

Embodiment 1

[0034] See figure 1 . The light guide plate includes at least one sub-light guide plate 10 . The sub-light guide plate 10 includes a light source part 101 for receiving light directly to the light source and an inwardly recessed light shield installation groove 102 disposed beside the light source part. The light source part and the shading cover installation groove are arranged on both sides of the sub-light guide plate. In this specific embodiment, the shading cover installation groove 102 is arranged at the lower part of the light source part. Certainly, the light source part and the shading cover installation groove may also be provided only on one side of the sub-light guide plate to form a single-sided light-incident structure. The light source part and the shading cover installation groove can also be arranged on four sides of the sub-light guide plate to form a four-sided light incident structure.

[0035] Please also see figure 2 . The lighting fixture 11 incl...

Embodiment 2

[0038] See image 3 . The sub-light guide plate 20 constituting the light guide plate also includes a light source part 201 and a shading cover installation groove 202, and the light source part and the shading cover installation groove are arranged on both sides of the sub-light guide plate. The difference between this embodiment and the first embodiment lies in that the setting of the light shield installation groove 202 is different. In this specific embodiment, there are four shading cover installation grooves, which are respectively arranged on two sides of the two light source parts. Certainly, the light source part and the shading cover installation groove may also be provided only on one side of the sub-light guide plate to form a single-sided light-incident structure. At this time, there are two light shield installation grooves, which are respectively arranged on two sides of the light source part.

Embodiment 3

[0040] See Figure 4 . The difference between this embodiment and the second embodiment is only that the light source portion 204 is slightly recessed into the side of the sub-light guide plate 205 .

Abstract

The invention discloses a light guide board, aiming to provide the light guide board which has no framework and is easy to assembly. The light guide board comprises at least one sub light guide board; each sub light guide board comprises at least one light source part for entering light by means of being opposite to the light source, and further comprises at least one light-shielding cover mounting groove which is concave inwards and is arranged besides the light source part. The invention further discloses an illumination lamp provided with the light guide board. The light guide board provided by the invention can be used for various illuminations, such as art illumination, decoration illumination, a light-emitting brick, a showcase, a cupboard, a display stand and the like.

Description

technical field [0001] The invention relates to the lighting field, in particular to a light guide plate and a lighting fixture. Background technique [0002] The light guide plate is often used in liquid crystal displays, which can uniformly guide and emit the light emitted by the light source. Since the light guide plate has good light guiding properties, the light guide plate has also been used in lighting fixtures to transmit light. However, the existing light guide plate is usually integrally formed as a whole piece. In order to be used in larger-sized lighting fixtures, multiple light guide plates are spliced ​​to form a whole light guide plate. When used in liquid crystal displays or lighting fixtures, the light source 92 is usually placed on the side of the light guide plate 91, and its structure is as follows: Figure 15 shown. In order to prevent light leakage, it is generally necessary to arrange a light shield 93 outside the light source 92, and the light shie...
