A light source module is provided. The light source module includes a lead frame, a light source, a cup part, and a reflector. The light source is disposed on the lead frame, wherein the light source provides a light. The cup part is disposed on the lead frame, wherein the cup part includes an opening, a plurality of thick-wall portions and a plurality of thin-wall portions. The thick-wall portions and the thin-wall portions surround the light source and define a space. The reflector covers the opening. At least a portion of the light is reflected by the reflector, and is emitted through the thick-wall portions and the thin-wall portions.

Light source module

A light emitting diode device includes a substrate, a frame, an LED die and a transparent layer. The frame is located on the substrate. The frame and the substrate collectively define a concave portion. The frame has a light reflectivity ranging from 20% to 40%. The LED die is located on the substrate and within the concave portion. The transparent layer is filled into the concave portion and covering the LED die, wherein the LED die has a side-emitting surface and a top-emitting surface, the side-emitting surface has a luminous intensity greater than that of the top-emitting surface.

Light emitting diode device

A light emitting diode (LED) device includes a transparent substrate, a first reflection layer, a LED chip, a positive electrode, a negative electrode and a wavelength-converting layer. The LED chip is disposed on a surface of the transparent substrate, and the first reflection layer is disposed between the LED chip and the transparent substrate. The positive electrode and the negative electrode are disposed on an end portion of the transparent substrate and are electrically connected with the LED chip. The wavelength-converting layer covers the first reflection layer and the LED chip.
