Light emitting device with transparent plate

A light emitting device, comprising:

• a carrier;
• a light emitting element, disposed on the carrier and electrically connected to the carrier;
• a transparent plate, disposed on the carrier, the transparent plate comprising:
• a flat-portion, having an upper surface and a lower surface relative to the upper surface, the lower surface directly disposed on the carrier;
• a lens-portion, covering the light emitting element, having a light incident surface and a plane surface and a positive camber connected to the upper surface, a curvature of the plane surface and a curvature of the positive camber being substantially different,
• wherein the light emitting element is suitable for emitting a light beam, a first partial beam of the light beam passes through the light incident surface and leaves the positive camber, a second partial beam of the light beam passes through the light incident surface and is transmitted to the plane surface, and the plane surface reflects at least a part of the second partial beam of the light beam to be passed through the positive camber.
