Abstract
A waterproof light bulb assembly implements a plurality of light emitting diodes (LEDs) for use in light fixture in an outdoor or wet environment. The light bulb assembly includes a plastic bulb shell which used a threaded portion to mate to a bulb cap. The bulb cap includes a passage to receive a light emitting assembly having a direct current (DC) connector. The light emitting assembly includes the plurality of LEDs and a printed circuit board. A switching circuit regulates current and heat emitted by the plurality of LEDs. The light bulb assembly also includes a socket to receive the plastic bulb shell and bulb cap.
Claims20
A waterproof light bulb comprising:
- a plastic bulb shell having a threaded portion corresponding to a first mating part;
- a plastic bulb cap to fit into the first mating part of the plastic bulb shell and having a passage centered therewithin;
- and
- a light emitting assembly having a direct current (DC) connector to fit through the passage within the bulb cap, wherein the light emitting assembly includes
- a printed circuit board to fit into a step of the plastic bulb cap and connected to the DC connector,
- a plurality of light emitting diodes configured on the printed circuit board to face upwards from the printed circuit board, and
- a switching (LC) circuit embedded on the printed circuit board configured to regulate an amount of current operating at a switching frequency within by the light emitting assembly.
A waterproof light bulb assembly comprising:
- a plastic bulb shell having an exterior threaded portion;
- a plastic bulb cap configured to fit within the plastic bulb shell and having a passage therein;
- a light emitting assembly having a direct current (DC) connector to fit through the passage within the plastic bulb cap, wherein the light emitting assembly includes
- a printed circuit board connected to the DC connector,
- a plurality of light emitting diodes configured on the printed circuit board to face upwards from the printed circuit board, and
- a switching (LC) circuit embedded on the printed circuit board to regulate an amount of current operating at a switching frequency within by the light emitting assembly;
- and
- a socket having an interior threaded portion to receive the exterior threaded portion of the plastic bulb shell, the socket including
- a female connector to receive the DC connector, and
- an O-ring positioned in the female connector to engage the DC connector.
A light emitting assembly for a light bulb, the light emitting assembly comprising:
- a direct current (DC) connector having a tab;
- a printed circuit board to connect to the tab of the DC connector;
- a plurality of light emitting diodes configured on the printed circuit board to face upwards from the printed circuit board;
- and
- a switching (LC) circuit embedded on the printed circuit board to regulate an amount of current operating at a switching frequency within by the light emitting assembly.
