Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0018] The present invention provides such Figure 1-2 The shown light guide plate uniformly emits light, including a combined light guide plate 1 spliced by several light guide strips 101 that are sequentially abutted against, and a reflective film 2 adhered to the light-emitting surface of the combined light guide plate 1. The gaps between the adjacent light guide strips 101 are evenly provided with several conical light guide holes 3, and the frustum-shap...

The invention discloses a light guide plate with uniform light output, which comprises a combined light guide plate spliced by several light guide strips which are adjacent to each other in sequence and a reflective film adhered to one side of the light output surface of the combined light guide plate. There are several frustum-shaped light guide holes evenly opened in the gap between the light guide bars. After splicing, the whole is curved. A lamp is also disclosed, comprising a light source, and the lamp further has the combined light guide plate according to any one of claims 1 to 4. The reflection frequency of light in the gaps of the combined light guide plate and in the light guide hole of the round table is faster, the travel of light in the light guide plate is longer, and the permeability is stronger, so as to ensure that the brightness of the entire light guide plate is stronger, and the light output is more uniform. The effect is better.
Description
technical field [0001] The invention belongs to the technical field, and in particular relates to a light guide plate for uniform light emission and a lamp thereof. Background technique [0002] The light guide plate is the main component of the backlight module. The light guide plate is made of optical-grade acrylic / PC board, and then high-tech materials with extremely high refractive index and non-absorbing light are used. With the rapid development of LED surface light sources in recent years, side light emission of LED surface light sources has gradually become the development trend of the lighting market. The main trend is that the performance of the light guide plate plays a very important role in the uniformity, brightness, and light efficiency of the light output. [0003] The light guide plate currently in use achieves uniform light output through laser engraving light guide holes, but in the case of thicker light guide plates or larger areas, the light penetration...
