An LED display panel structure comprises a PC board, a front plate having a plurality of through-holes defined thereon, a plurality of washers, each of which is provided on a back surface of the front plate in correspondence with each of the through-holes, a plurality of LEDs, each of which is inserted through a central aperture of each of the washers being smaller than a diameter of the LED to be clamped therein, and a plurality of holders, each of which has a first recess and a second recess, each of the holders receives and holds each of the LEDs in its first recess and is attached on the PC board by water resistant adhesive filled in the second recess. A pair of through-bores communicating the first recess with the second recess are defined therebetween to allow a pair of leads of each of the LEDs to extend therethrough and connect to the PC board. Such a structure can prevent moisture from seeping in to damage the LEDs.

A receptacle for light emitting diodes includes a housing defining an opening at one end and having a bottom at another end; a first positioning device being a disk adapted to be received in substantially a middle inner periphery of the housing, defining a plurality of holes each of which receives a corresponding light emitting diode; and a second positioning device being a disk including a plurality of holes each of which encloses a head portion of a corresponding one of the light emitting diodes, thereby retaining an axis of each light emitting diode in a same direction.

Receptacle apparatus for light emitting diodes

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.
