Abstract: A lighting device is disclosed, including an LED die, a light-transmissive encapsulant and a light-transmissive wall. The light-transmissive encapsulant covers the light-emitting side surfaces and the top surface, and the light-transmissive wall surrounds the light-transmissive encapsulant and covers the side surfaces of the light-transmissive encapsulant. Furthermore, the refractive index of the light-transmissive encapsulant is not greater than the refractive index of the light-transmissive wall. A lighting module is further disclosed, including a circuit substrate and the lighting devices, as described above, which are disposed on the circuit substrate. Therefore, when lights generated from the LED die are transmitted into the light-transmissive wall from the light-transmissive encapsulant, the lights will be deflected towards the lateral direction, thereby increasing the viewing angle of the lighting device.
