LED device, method of manufacturing the same, and light-emitting apparatus

An LED device to be connected to a socket connector, comprising:

• a device body made of plastic and having a first surface and a second surface opposite to the first surface;
• a plurality of metal contacts insert-molded in the device body and each having a first end portion placed on the first surface and a second end portion opposite to the first end portion;
• and
• a plurality of LED bare chips mounted directly on the first end portions of the metal contacts, respectively,
• wherein the second end portions of the metal contacts protrude outward of the device body from the second surface, thereby forming terminal portions each of which has a plate shape perpendicular to the second surface,
• wherein each of the terminal portions extends lengthily along the second surface to fit snugly with an elongated socket of the socket connector, and
• wherein power supply to the LED bare chips and heat radiation from the LED bare chips are carried out through the metal contacts.
