An edge LED package includes a base, an LED die and a reflective cup. The LED die is located on a surface of the base. The reflective cup includes an inner sidewall surrounding the LED die. The inner sidewall inclines outward from the base to form an included angle from 140 to 150°. The depth of the reflective cup, measured vertically from top of the reflective cup to the bottom, is about 0.25 mm to 0.3 mm. The area ratio between the opening area of the reflective cup and the base area surrounded by the reflective cup is about 1.5 to 2.
