ABSTRACT:
A receptacle for light emitting diodes includes a housing defining an opening at one end and having a bottom at another end; a circuit board from which a plurality of light emitting diodes extend being adapted to be received in substantially a middle inner periphery of the housing; a hole being defined in a periphery of the housing; a ridge being longitudinally formed along an inner periphery of the housing; a stop being formed beside the ridge substantially in a same longitudinal level with respect to the hole; a light-resistant device including a ring frame across which a plurality of louvers are connected, a groove defined at an outer periphery of the ring frame, a snapping member being formed on the outer periphery of the ring frame diametrically opposite to the groove; whereby the light-resistant device is positioned at substantially the opening of the housing, with the groove of the light-resistant device receiving the ridge of the housing and the snapping member of the light-resistant device being retained in the hole, a portion of the outer periphery defining the groove abutting against the stop of the housing.
