Claim 0:
1. A light emitting device, comprising:
a base including a first substrate and n through holes, wherein each of the n through holes passes through the first substrate;
a conductive unit including m conductors, wherein the m conductors are separate from each other and each of the m conductors passes through the first substrate, wherein each of the m conductors includes a chip bonding pad disposed on a top surface of the base, a solder pad exposed from a bottom surface of the base, and a first connection connected between the chip bonding pad and the solder pad, and wherein a part of the first connection is arranged in the through hole;
a light unit correspondingly and electrically connected to the m conductors; and
a package including a first package body and a second package body, wherein the first package body surrounds the light unit, and the second package body covers the light unit and the first package body;
wherein the first package body and the second package body have different optical properties;
wherein m and n are integers greater than or equal to 2, and m is greater than or equal to n;
wherein the first package body has a contact part, and the contact part is adjacent to the light unit, and a surface of the contact part is in a shape of a round corner, a bevel, or an arcuate slot;
wherein a maximum thickness of the contact part of the first package body is not more than 1.5 times a height of the light unit, and a minimum thickness of the contact part is not less than 0.5 times the height of the light unit.
