An LED inspection lamp has plurality of LED sources for emitting electromagnetic radiation at different peak wavelengths for causing visible fluorescence in different leak detection dyes. A lens is associated with each LED. Radiation passing through lenses is superimposed in target area at target distance. Another LED inspection lamp has plurality of LEDs emitting electromagnetic radiation at a peak wavelength. A lens adaptor has lens housing for attachment to LED inspection lamp with a single LED for causing visible fluorescence, and a lens. Substantially all of the radiation from the LED passes through the lens and is focused in a target area at a target distance from the lenses. LED spot lights have a similar configuration. The LEDs may produce white light from distinct LEDs or from white LEDs. The light may be a flashlight or fixed spot light.

A manifold gauge set has at least one sight glass window for viewing contents of a refrigeration system or an air conditioning system being serviced. The window may be non-planar to achieve an appearance that varies with the presence or absence of liquid. Such a non-planar window may be in the form of a dome, prism or a fresnel lens. The gauge set may have a second light transmissive window to allow light to illuminate system contents being viewed. A light source may be provided to illuminate system contents being viewed. The light source may provide light through the same window that is used for viewing contents. A diffuser may be provided with a second window to achieve an illuminated background for viewing system contents. Similar configurations may be used in standalone sight glasses, vacuum pumps, and recovery machines.

A work light having a work light body including handle section and light head section, an elongate housing, a battery compartment and a component chamber longitudinally aligned within the housing, a battery, an LED circuit board assembly extending longitudinally within the housing and having a substrate layer, an external component layer on a first side of the substrate layer, and a driving component layer on an opposing second side of the substrate layer. Overlapping portion of the LED circuit board assembly in close proximity to the battery. Also, at least one LED on the external component layer, the external component layer facing transaxially outwardly from the housing such that light emitting from the LED emits from the light head section. At least one driving component on the driving component layer, all driving components placed on an extending portion of the LED circuit board assembly over the component chamber.

Compact LED work light

An LED work light has multichip LEDs and a diffusing dome. Each LED may have separate electrical terminals for each chip. The LED work light may have convex lenses forward of each LED. Convex lenses may be hemispherical. Convex lenses may have a nonhemispheric curved surface whose cross section has at least one circular arc and no non-circular arcs. The LED work light has a battery or receives power from an external power source. The LED work light may have a transparent plastic tube as a structural member. A replaceable plastic cover may be added to protect any structural tube or other major transparent part of the LED work light from abrasions. The plastic cover may be tubular. The plastic cover may comprise laminations of plastic that can be removed individually after being abraded. Any external power source may be a wall transformer type and may have current limiting means. The LEDs may be attached to the rear surface of an LED PCB that is fastened to a heatsink in a manner achieving thermal contact between the rear surfaces of the LEDs and the heatsink. A position sensing switch may be used.

LED lamp has LEDs aimed rearwards with either a concave mirror to the rear of each LED, or one concave mirror to the rear of two or more LEDs, collecting the light from the LEDs to form a forward projecting beam. LEDs may be high power types that require heatsinking. LED lamp may have a lens forward of each LED to collimate the radiation produced by the LEDs into a beam, where at least one lens has at least one aspheric curved surface. LED lamp may have a transparent reflective optic to collimate the radiation produced by each LED into a beam. For an inspection lamp, the LEDs typically have a peak wavelength of 395 to 415 nanometers for seeing the area being irradiated but not so visible as to overwhelm fluorescence of fluorescent materials to be detected. Other wavelengths may be used. LED inspection lamp has a combination of LEDs of different wavelengths or a combination of at least one LED and at least one other light source such that the lamp produces radiation suitable for detection of materials to be detected and adequately illuminates the area being irradiated. LED lamp has LEDs that produce a beam of suitable radiation with a width of 10 degrees or less without additional optics. LED inspection lamp has head attached to a flexible member, with head serving as heatsink for one or more high power LEDs. Current regulator circuits are also disclosed.

The use of sealants based on organosilanes for refrigeration and air conditioning systems is made possible by control of the rate of introduction and viscosity of the sealant mixture within certain ranges. An appropriate choice of organosilane sealant is made to allow effective sealing of small pinhole size leaks in the air conditioning or refrigeration system. The organosilane is then combined with a miscible lubricant at particular ratios to provide the proper mixture viscosity for injection into the refrigerant system to prevent bearing seizure. Specific orifice sizes are selected for an apparatus to ensure that the composition is injected at the flow rates required to prevent liquid slugging and subsequent compressor shutdown or failure. In addition, effective introduction of the mixture requires certain procedures be performed. Injection procedures are also described that prevent temporary or catastrophic equipment shutdown.

Composition and methods for injection of sealants into air conditioning and refrigeration systems
