Multicolor LED lamp bulb for underwater pool lights

Abstract

A multicolor LED lamp bulb includes a hollow lamp body which has a substantially tapered intermediate portion, a longitudinal portion and a stem portion, a lens sealingly engaged with the longitudinal portion, a plurality of different colored LED bulbs mounted in a predetermined spaced-apart arrangement on a circuit board wafer mounted inside the lamp body in an orientation normal to the central axis of the lamp body, a controller circuit electrically connected wherein predetermined arrays of the plurality of different colored LED bulbs activate at predetermined sequences for predetermined time intervals, and a screw-type base affixed to the stem portion and adapted to engage a conventional lamp socket. The controller circuit includes a rectifier circuit for converting a 12 volt-ac source applied to the LED lamp bulb to a 12 volt-dc circuit for supplying electrical power to the arrays of the plurality of different colored LED bulbs. The lens includes a grid of grooves in opposite sides of the lens, the grooves on one side being oriented approximately 90° from a direction of the opposite side grooves.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to lamp construction using light emitting diode (LED) technology to provide multicolor effects in pools and spas.[0003]2. Description of Related Art[0004]Pool lighting is typically provided by a watertight encasement mounted at one or more locations in the wall of a pool below the waterline. Generally, a clear incandescent bulb rated for 12 volt-ac is used. If a color effect is desired, the encasement must be removed from the wall surface and pulled above the waterline. After removal of the watertight lens, a colored incandescent lamp can be screwed into the lamp socket. The lens is reinstalled and the encasement is placed back into the wall. The pool owner then has a constant single color effect within the pool. Another method of providing changing color effects in water includes a device for an aquarium wherein fixed lamps in combination with rotating transparent plates of varying colors are used...

AI Technical Summary

Benefits of technology

[0018]The invention is adapted such that it can be used to replace the bulbs currently used in underwater pool light sockets, where a 12 volt-ac power source is supplied through the socket. This novel and nonobvious invention will provide pool owners, residential and commercial, an inexpensive way to have a beautiful display of changing colored lights within their pools.

Problems solved by technology

The aforementioned devices do not provide the ability to have a multicolor effect in underwater applications wherein the LEDs are sequenced to turn on predetermined arrays of different colored LEDs thereby providing a pool or spa owner with a dynamic multicolored illumination effect to this or her pool or spa.
