Abstract
A method of waterproofing a strobe flash unit for use in underwater photography. A mold is formed and a strobe flash unit is mounted within the mold. Epoxy resin is poured into the mold to surround the strobe flash unit with the resin. The resin is then cured until it hardens, at which time the mold is removed from the epoxy resin and strobe flash unit. The resultant product is a strobe flash unit encapsulated in a transparent waterproof casing.
Claims11
A method of waterproofing a strobe flash unit including a synchronizing switch actuated by cable means and power supply for use in underwater photography, comprising:
- providing an elastomer mold;
- mounting a strobe flash unit and power supply within said mold;
- forming an aperture through one surface of said mold;
- extending a cable slightly larger than said aperture through said aperture to said strobe flash unit;
- attaching said cable to said synchronizing switch to operatively connect said cable and said switch;
- electrically connecting said strobe flash unit, said switch and said power supply;
- pouring epoxy resin into said mold to surround said strobe flash unit and power supply;
- curing said epoxy resin in said mold;
- removing said mold from said epoxy resin, whereby said strobe flash unit and power supply are encapsulated in a waterproof casing of epoxy resin.
A method of waterproofing a strobe flash unit including a power switch having a base and an actuating mechanism to connect said strobe flash unit to a power source for use in underwater photography, comprising:
- providing an elastomer mold;
- mounting a strobe flash unit, power switch, and power source within said mold;
- forming an aperture in one surface of said mold;
- extending the base of the power switch through said aperture into said mold;
- electrically connecting said power switch to said strobe flash unit and said power supply;
- pouring epoxy resin into said mold to surround said strobe flash unit, power switch, and power source;
- curing said epoxy resin in said mold;
- removing said mold from said epoxy resin, whereby said strobe flash unit, power switch, and power source are encapsulated in a waterproof casing of epoxy resin.
A method of waterproofing a strobe flash unit including a light actuated synchronizing assembly contained in a housing and power supply for use in underwater photography, comprising:
- providing an elastomer mold;
- mounting a strobe flash unit and power supply within said mold;
- electrically connecting said synchronizing assembly with said strobe flash unit;
- electrically connecting said strobe flash unit and said power supply;
- mounting said synchronizing assembly within said mold;
- pouring epoxy resin into said mold to surround said strobe flash unit and power supply;
- curing said epoxy resin in said mold;
- removing said mold from epoxy resin, whereby said strobe flash unit and power supply is encapsulated in a waterproof casing of epoxy resin.
A strobe flash unit and power supply adapted for use in underwater photography, comprising:
- means for emitting light including:
- a lamp;
- energizing means electrically connected to a power supply for energizing said lamp;
- a power switch for connecting and disconnecting said power supply from said energizing means;
- said lamp, energizing means, power supply, and power switch constituting a means for emitting light;
- and
- water tight casing means enclosing said means for emitting light for preventing water from contacting said means for emitting light, said casing means encapsulating said means for emitting light.
A strobe flash unit and power supply adapted for use in underwater photography, comprising:
- means for emitting light;
- a power supply electrically connected to said means for emitting light;
- water tight casing means enclosing said means for emitting light and said power supply for preventing water from contacting said means for emitting light and said power supply, said casing means encapsulating said means for emitting light and said power supply;
- and
- recharging connector means partially embedded in said casing means and electrically connected to said power supply for providing electrical connection for detachably engaging a supplementary energy source to said power supply for recharging said power supply.
