Light emitting bulb

A light-emitting device, comprising:

• a carrier having a top surface, a first surface, a second surface, and a third surface which is longer than the first and second surfaces;
• a first electrode pad and a second electrode pad disposed on the carrier;
• a first electrode strip disposed on the top surface, and having a first region and a first stripe, the first stripe electrically connected to and extending out from the first region along a direction from the first surface to the second surface, the first region being narrower than the first and second electrode pads;
• a second electrode strip disposed on the top surface, and having a second stripe and a branch, the second stripe electrically connected to and extending from the second electrode pad along the direction from the first surface to the second surface, the branch electrically connected to and extending out from the second stripe along a direction not parallel to the direction from the first surface to the second surface;
• and
• a first plurality of light-emitting units electrically connected to the first region, and arranged between the first region and the second surface,
• wherein a distance between the second electrode pad and the first surface is shorter than a distance between the first region and the first surface.
