Abstract: A radial type light-guiding plate comprises a light source, a light-guiding plate, and a reflective component. The top face of the light-guiding plate is a light output face, and the bottom face thereof is a reflective face. The light source is disposed at sides of the light-guiding plate. The reflective face has channels, which radiate toward the sides near the light source. Because the channels are radial, the reflected light rays in the range of the light-guiding plate near the light source will be less. The light emission near the light source thus will not be too bright. Because the channels of the light-guiding plate that are far from the light source are closer together, light rays can be effectively transmitted thereto to increase the brightness of light emission therefrom, hence letting the brightness of the whole light output face be more uniform.

Abstract: An improved straight down-type backlight module assembly structure is described. A groove is disposed in a base in a position that facilitates detachment. The groove is used to receive a light-emitting component. When the light-emitting component is to be maintained or replaced, it is not necessary to make many unnecessary detachment actions, hence facilitating detachment and maintenance of the light-emitting component.

Abstract: A vertically downward back-light module of the invention comprises a light-guiding panel, a light source, a reflective element, and a base. The light-guiding panel includes a bottom reflecting surface in which is formed a slot having a corrugated diffusing surface and light entry side surfaces. The light-guiding panel includes lateral wings respectively extending at a side of each light entry side surface. Each lateral wing extends in inclination relative to a horizontal plane including the opening of the slot in which is placed the light source. The reflective element covers the bottom reflecting surface and encapsulates the light source in the light-guiding panel. The light-guiding panel with the light source are mounted on the base. The light from the light source partially travels through the corrugated diffusing surface, and partially through the lateral wings. The brightness in proximity of the light source is thereby reduced.
