Light emitting unit

A light emitting unit, comprising:

• a reflective structure having a recess formed by inner side surfaces thereof, and the reflective structure including a side opening and a bottom opening corresponding to the recess, wherein the side opening and the bottom opening are adjacent to each other, and the inner side surfaces are defined as a top surface and a surrounding side surface, and wherein the reflective structure is recessed from the side opening and the bottom opening toward the inside and thus the recess is formed;
• a light transmitting body disposed within the recess and doped with fluorescent powder, and comprising:
• a light emitting surface corresponding to the side opening;
• and
• an electrode exposing surface corresponding to the bottom opening;
• and
• a light emitting chip partially disposed within the light transmitting body and having a bottom surface, a top light emitting surface and a plurality of side light emitting surfaces that are connected to the bottom surface and the top light emitting surface, wherein the bottom surface comprises two electrode portions exposed from the electrode exposing surface;
• wherein the light transmitting body covers a portion of the light emitting chip, and a distance from the top light emitting surface to the top surface is not less than 50 μm;
• wherein a cross-section width of the recess increases toward the side opening.
