Abstract: An LED bulb structure includes a heat dissipation base, a power connector, a light-emitting module, an insulation cover, and a light-guiding cover. The power connector is disposed on a bottom side of the heat dissipation base. The light-emitting module includes a circuit substrate disposed on a top side of the heat dissipation base and a plurality of LED chips electrically connected to the circuit substrate. The LED chips are surroundingly disposed on the circuit substrate and adjacent to an outer perimeter surface of the circuit substrate. The insulation cover is disposed on the circuit substrate, and the insulation cover has a surrounding main portion and a convex portion disposed on a top side of the surrounding main portion. The light-guiding cover is disposed on the insulation cover. The light-guiding cover has a through opening formed on a top side thereof for exposing the convex portion.

Abstract: A light-emitting device for generating a specific light pattern and a light-guiding unit thereof are disclosed. The light-guiding unit includes a light-guiding plate, a reflective layer having a first predetermined reflectance disposed between the light-guiding plate and the bridge support, a patterned light-guiding microstructure with a predetermined pattern having a second predetermined reflectance disposed between the light-guiding plate and the reflective layer, and a light uniform microstructure disposed on the light-guiding plate and correspondingly opposite to the patterned light-guiding microstructure, and the first predetermined reflectance of the reflective layer is different from the second predetermined reflectance of the patterned light-guiding microstructure.

Abstract: An LED illumination module for generating uniform stripped light source includes a stripped light-guiding unit, a stripped reflective unit and a light-emitting unit. The stripped light-guiding unit has a light-guiding body and a plurality of first light-guiding microstructures disposed on a top side of the light-guiding body. Each first light-guiding microstructure has a first reflective index. The stripped reflective unit has a reflective body corresponding to the light-guiding body and a reflective layer formed on an inner surface of the reflective body. The stripped reflective unit covers one part of the light-guiding body, the first light-guiding microstructures are disposed between the light-guiding body and the reflective layer, and the reflective layer has a second reflective index that is different from the first reflective index. The light-emitting unit has a first light-emitting module disposed beside one end of the light-guiding body.

Abstract: A light-emitting device for increasing light-emitting efficiency by destroying total reflection includes a substrate unit, a light-emitting unit, a strip light-guiding unit and a cover unit. The light-emitting unit has a plurality of light-emitting modules disposed on the substrate unit. The strip light-guiding unit has a plurality of strip light-guiding elements corresponding to the light-emitting modules and a plurality of strip reflective elements respectively disposed on the strip light-guiding elements. Each strip light-guiding element has a light-inputting surface facing each light-emitting module, a reflective surface and a light-outputting surface, each strip reflective element is disposed on the reflective surface of each strip light-guiding element, and the light-outputting surface is a rough surface for destroying total reflection. The cover unit has a light-permitting cover coupled with the substrate unit for selectively covering the light-emitting unit and the strip light-guiding unit.
