A utility drop light having a shield for directing light in a particular direction and preventing the light from shining in the user's eyes is provided according to the invention. The utility drop light includes a translucent light tube having a first end and a second end, a light source positioned within the translucent light tube between the first and second ends thereof, and a light shield extending from the first end of the translucent light tube to the second end of the translucent light tube. The light shield is positioned between the translucent light tube and the light source. The light shield is rotatable relative to the light tube and is weighted such that the light shield is always positioned above the light source relative to the earth.

A portable lighting device includes a body, a lighting unit supported by the body, a frustoconically-shaped lens coupled to the body and surrounding the lighting unit, a terminal block supported by the body, and a hanging cable configured to hang the body from a support structure. The lighting unit includes a light emitting diode and a heat sink. The terminal block is configured to connect to a power source and provide electrical energy to the lighting unit to illuminate the light emitting diode.

In one aspect, a light module is disclosed, which includes a housing providing a hollow chamber extending from a proximal end to a distal end, and a lens positioned in the hollow chamber, where the lens has a lens body comprising an input surface for receiving light from a light source and an output surface through which light exits the lens body, said lens further comprising a collar at least partially encircling said lens body. The light module further includes at least one shoulder on which the lens collar can be seated for positioning the lens within the housing. A light source, e.g., an LED, is coupled to the hollow chamber, e.g., at its proximal end, for providing light to the lens.

A hazardous location light source module includes a metal base carrier having a light-module support surface on its upper side and a mounting stem on its lower side. The light-module support surface supports a light-module substrate mounting one or more light-emitting devices. The mounting stem is configured for mounting the light source module to a modular hazardous location light source assembly. A wiring port extending through the mounting stem to the base carrier upper side receives electrical wiring that connects electrically to the light-emitting device(s). A main-lens support surface on the base carrier upper side supports a light-transmitting main lens that comprises chemically strengthened glass and has a maximum dimension to maximum thickness ratio of not less than approximately 40:1. The main lens is permanently secured to the base carrier by virtue of a base carrier periphery being deformed into a lip that folds over to capture the main lens.

In one aspect, a handheld lighting system is disclosed, which comprises a handheld housing extending from a proximal end to a distal end, and a light module disposed at least partially in the housing. The handheld lighting system further includes a removable and replaceable power module that is coupled to the housing (e.g., it is at least partially disposed within the housing) and is electrically coupled to the light module, e.g., through a pair of electrical leads, for providing electrical power thereto. Light intensity from the light module may be controlled from a knob on the power module. Various adapters can allow the lighting system to attach to a multitude of medical, industrial, dental or veterinary endoscopes or other instruments.

A lighting apparatus and method for making the same are presented. In some aspects the apparatus includes a plurality of LED light sources mounted to a metal circuit board in a housing of the apparatus. In other aspects a light-permissive potting compound is disposed in the space between the LEDs and circuit board and the housing of said apparatus so as to permit exit of light from said LEDs while providing mechanical protection for the circuit board and LEDs and removing heat generated from said LEDs.

A lighting system for surface inspection includes an elongated substrate onto which a linear array of lights is mounted to provide extended light coverage. The lights may be dimmable and controlled by a circuit board to reduce veiling glare. A heat sink may disperse heat built up from the linear array of lights. A handle and articulated drop-in pin may provide means to focus all the lights in the same direction and point the lights onto a surface using a single hand or during hands-free use.
