Light-emitting diode package

Light-emitting diode (LED) packages, and more particularly arrangements of light-altering coatings in LED packages are disclosed. Exemplary LED packages may include lead frame structures that are at least partially encased by a housing. Arrangements of light-altering coatings may be provided that cover one or more portions of lead frame structures exposed within LED package recesses. By providing light-altering coatings that cover lead frame structures within package recesses, negative impacts from potential lead frame discoloration due to environmental exposure may be reduced. Additionally, such light-altering coatings may be configured to reflect light emissions from LED chips before reaching portions of lead frame structures. Light-altering coating arrangements are disclosed where light-altering coatings are arranged in contact with LED chips or, alternatively, in a spaced relationship with LED chips. Retention structures are disclosed that may define boundaries of light-altering coatings along recess floors of corresponding LED packages.

Group III nitride based light emitting diode (LED) structures include multiple quantum wells with barrier-well units that include III nitride interface layers. Each interface layer may have a thickness of no greater than about 30% of an adjacent well layer, and a comparatively low concentration of indium or aluminum. One or more interface layers may be present in a barrier-well unit. Multiple barrier-well units having different properties may be provided in a single active region.

An article of manufacture for providing a water salinizer to add salt to pool water is disclosed. The water salinizer includes a barrel having a sidewall, a convex bottom, an angled sidewall between the convex bottom and the side wall, and an opening is a top surface for dissolving material into water, an input port coupled to the angled sidewall and being configured with the convex bottom to direct an incoming pressurized water stream and salt around the barrel along the angled sidewall, and a discharge port coupled to the sidewall about the opening in the top surface on an opposite side of the barrel from the input port.

Group III nitride light emitting diode (LED) structures with improved electrical performance are disclosed. A Group III nitride LED structure includes one or more n-type layers, one or more p-type layers, and an active region that includes a plurality of sequentially arranged barrier-well units. In certain embodiments, doping profiles of barrier layers of the barrier-well units are configured such that a doping concentration in some barrier-well units is different than a doping concentration in other barrier-well units. In certain embodiments, a doping profile of a particular barrier layer is non-uniform. In addition to active region configurations, the doping profiles and sequence of the n-type layers and p-type layers are configured to provide Group III nitride structures with higher efficiency, lower forward voltages, and improved forward voltage performance at elevated currents and temperatures.

The present invention discloses a waterproof relief outlet in a chest wader. A waterproof folded funnel having a pair of inner flanges at one end is secured through a center seam of the chest wader. A funnel housing having an inner flap and an outer flap is attached to a back side of the center seam of the chest wader in conjunction with the inner flanges of the funnel. An interlocking tongue is also provided with the inner and outer flaps of the funnel housing. A wearer of the chest wader can relieve his pressure by unlocking the interlocking tongue and unfolding the inner and outer flaps of the housing through which the folded funnel is extended and unfolded.
