A lighting device is disclosed having a plurality of light emitting diodes of varying light intensities disposed about the same substrate. A lens is configured with a geometry that corresponds to different sections of the substrate containing the light emitting diodes of different light intensities.

Light assemblies comprise a housing having a chamber, one or more light emitting elements connected with the housing, a transparent cover, and one or more reflectors positioned adjacent the light emitting element. The one or more light emitting elements are interposed between the transparent cover and the one or more reflectors, and the one or more light emitting elements and one or more reflectors operate to provide a multi-directional field of illumination that is 180 degrees or more, e.g., between about 180 to 270 degrees. The transparent cover may have a convex outer surface to facilitate light transmission in side oriented directions. The light assembly may include switches or controls for on/off and/or dimming functions. An example light assembly comprises three light emitting elements in the form of LEDs, and includes three reflectors, wherein the LEDs and reflectors are configured to produce the desired field of illumination.

The invention provides a portable lighting device with an elongated main body that includes a housing with receiver, and a power source positioned within the receiver. An operational mode selector assembly with a switch assembly that is actuated by a user is operatively coupled to the power source. An illumination assembly is electrically coupled to both the operational mode selector and the power source. The illumination assembly has a primary light source with a light emitter that emits light axially along a longitudinal axis of the main body or housing through a lens. A secondary light source with a light emitter emits light substantially perpendicular to the axis to illuminate an indicia located in a side region of the illumination assembly. During operation of the portable lighting device, the components of the illumination assembly are arranged such that: (i) the primary light source does not illuminate the indicia, (ii) the secondary light source does not emit light through the lens, (iii) an appreciable amount of light emitted from the primary light source does not mix with light that is emitted from the secondary light source within the portable lighting device, and (iv) an appreciable amount of light emitted from the secondary light source does not mix with light that is emitted from the primary light source within the portable lighting device.

Various embodiments for a headlamp having a detachable flashlight are disclosed. The headlamp includes a head guard and a detachable flashlight. The head guard is adapted to be worn on a head of an operator, and includes a first battery, a first electrical contact, and a first magnet. The detachable flashlight is configured to detachably attach to the head guard, and includes a second battery, a second electrical contact and a second magnet. When the second magnet is positioned near the first magnet, the detachable flashlight magnetically couples to the head guard and aligns the second electrical contact with the first electrical contact/The head guard includes processing circuitry configured to provide power to and charge the second battery of the detachable flashlight in an instance in which the detachable flashlight is coupled to the head guard.

A lighting device is disclosed having a plurality of light emitting diodes of varying light intensities disposed about the same substrate. A lens is configured with a geometry that corresponds to different sections of the substrate containing the light emitting diodes of different light intensities.

An improved light assembly includes aligned directional light sources mounted one behind another. A distal one of the light sources occludes light emitted from a proximal one of the light sources. A reflector is interposed between the light sources, with a convex surface facing the proximal one of the light sources. Thus, the light assembly projects a light field extending at least through an 180 hemisphere, and up to about 270 backwards from the forward orientation of the light field, well-illuminating lateral approaches to the assembly.

Various embodiments for a headlamp having a detachable flashlight are disclosed. The headlamp can include a head guard ergonomically contoured to be worn on a head of an operator, for instance, using one or more straps. The head guard can include a cavity, where the cavity includes a first electrical contact and a first magnet positioned therein. The detachable flashlight is adapted to be positioned in the cavity of the head guard. The detachable flashlight can include a second electrical contact and a second magnet. The first magnet is sized and positioned to orient a rear face of the detachable flashlight to align the second electrical contact of the detachable flashlight with the second electrical contact positioned in the cavity.

There is provided a hand held flashlight having different intensity and direction of projected light controlled by switches which function independently or pently.
