发明名称 LIGHT EMITTING DEVICE AND FABRICATING METHOD THEREOF
摘要 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.
