Abstract: A light emitting device and a fabricating method thereof are described. The light emitting device includes a substrate, a light emitting chip, a tubular structure, and a fluorescent conversion layer. The tubular structure is formed on a surface of the substrate. The light emitting chip is disposed on the surface of the substrate and is surrounded by the tubular structure. The fluorescent conversion layer is disposed in the tubular structure and covers the light emitting chip. A ratio of a maximal vertical thickness and a maximal horizontal thickness of the fluorescent conversion layer at the light emitting chip is between 0.1 and 10. A distance for the light ray to pass through the fluorescent conversion layer is controlled by using the tubular structure, so as to solve a problem of the conventional art that fluorescent powder coating package technique results in non-uniform color temperature of the emitted light.

Abstract: A light emitting device and a fabricating method thereof are described, wherein the light emitting device includes a substrate, a wall, a first LED chip and a light conversion filling. The first LED chip is disposed on a surface of the substrate. The wall is disposed on the surface of the substrate, and surrounds the first LED chip. A first angle between a central axis of the wall and an inner surface of the wall is 0 degree or is acute, a second angle between the central axis of the wall and an outer surface of the wall is 0 degree or is acute, and the outer surface of the wall and the substrate has a space therebetween. The light conversion filling is surrounded by the light conversion wall, and is disposed on the first LED chip.

Abstract: A fluid sterilization device including a reaction chamber body, a light source, a fluid sensor and a controller is provided. The reaction chamber body has a reaction chamber through which a fluid passes. The light source is used to emit a light to the reaction chamber. The fluid sensor is used to detect the passage of the fluid and accordingly output. The controller is used to control the light source to emit the light in response to the signal.
