Abstract:
1. A semiconductor light emitting device configured to emit light along an optical axis, the semiconductor light emitting device comprising: a first side surface extending substantially parallel with the optical axis; a second side surface extending substantially parallel with the optical axis; an insulating support; a pair of electrodes formed on the insulating support; a housing including a groove having a bottom, the housing disposed adjacent the insulating support and exposing a portion of the pair of electrodes at the bottom of the groove; a semiconductor light emitting element disposed adjacent the bottom of the groove and connected to the exposed portion of the pair of electrodes; a sealing resin filled in the groove of the housing and including a light emission side through which light from the semiconductor light emitting element passes; each of the insulating support, the pair of electrodes, the housing, and the sealing resin including a first end face and a second end face, wherein each of the first end faces are substantially flush with one another and define the first side surface and each of the second end faces are substantially flush with one another and define the second side surface; the first end face of the sealing resin having a width extending in a direction perpendicular to the optical axis and including, the second end face of the sealing resin having a width extending in a direction perpendicular to the optical axis and including, a first light-shielding reflective member on the first side surface, extending in a direction of the optical axis from a position adjacent the first edge of the sealing resin to at least a position adjacent the second edge of the sealing resin, and extending in a direction perpendicular to the optical axis by a distance substantially equal to the width of the first end face of the sealing resin; and a second light-shielding reflective member on the second side surface, extending in a direction of the optical axis from a position adjacent the third edge of the sealing resin, beyond the fourth edge of the sealing resin, to a position that lies on the second end face of the insulating support, and the second light-shielding reflective member extending a distance substantially equal to the width of the second end face of the sealing resin.
