Optionally an emergency LED may also be included. A heat sink is connected to the housing and printed circuit board. Each of the plurality of the LEDs is mounted on the heat sink. A reflector is disposed inside the housing such that the light from the LEDs is mixed together and projected out of the illumination end of the housing by the surface of the reflector. The lighting fixture is received into a mounting flange assembly. A method for providing illumination using the above.
Abstract:
A light module (1) comprising a plurality of radiation-emitting semiconductor components (2), each of which is assigned an emission angle (2φ), comprising at least one component having an optical element (9) that enlarges the emission angle (2φ), and comprising a common optical device for focusing the radiation. The radiation is intermixed by means of the optical element (9). Also disclosed is a light multiple module (16), which has at least two light modules (1).
Abstract:
A light emitting diode lighting device and system that can be used for illuminating the interior and/or exterior of vehicles, aircraft, watercraft, signage or buildings is provided. It includes a voltage feedback constant current power supply circuitry and high power LEDs. The printed circuit assemblies are firmly mounted onto a continuous or semi-continuous mounting channel case that also works as a heat sink. By this means, it not only increases the reliability of the LED lighting tube but also it provides sufficient heat dissipation capability for the heat generated by the LEDs. Since the operating temperature of the LEDs is controlled and stays in cool condition, it dramatically increases the LED's lifetime and efficiency. The end caps of this LED lighting device are fully compatible with existing conventional fluorescent light fixtures and can directly replace those fluorescent lighting tubes in vehicles, mass-transit, watercrafts, aircrafts, signage or buildings with minimal modifications.
Abstract:
A retrofit HID lamp assembly, for use in a non-HID lighting receptacle, to provide HID illumination. The lamp assembly includes (i) a housing of a non-HID lamp assembly, (ii) a base terminal structure coupled with the housing, and compatible with such non-HID lighting receptacle, (iii) a ballast unit in the interior of the housing, (iv) a reflector overlying the ballast unit in the interior of the housing, (v) an HID lamp mounted in the interior of the housing so that light generated by the HID lamp is reflected by the reflector, with the HID lamp being electrically coupled with the ballast unit, and (vi) a lens coupled with the housing. A corresponding fabrication methodology is described. The retrofit HID lamp assembly may be used to retrofit existing lighting installations, such as PAR receptacles in exterior aircraft lighting systems, to cost-efficiently improve the illumination provided by such systems.
Abstract:
Anti collision light for an aircraft includes a number of light emitting diodes (LEDs) arranged on a common plane. A reflecting arrangement is located above the plane and reflects the light emitted by the diodes in a sidewards direction. A surrounding reflecting arrangement can be provided around the diodes and an additional reflecting arrangement in form of a layer on the plane may also be utilized. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
Abstract:
An LED light bulb has a bulb base having an electrical contact, an outer sidewall, an insulator between the electrical contact and the outer sidewall. The LED light bulb further includes a bulb circuit board mounted upon the bulb base and extending upwardly therefrom. The bulb circuit board has a first side and a second side. A plurality of LEDs are mounted on the first and second sides of the bulb circuit board such that the plurality of LEDs are in electrical communication with the electrical contact through a resistor. A flange extending outwardly from the outer sidewall adjacent a bottom edge of the outer sidewall.
Abstract:
A method for replacing non-HID landing and taxi lights in an aircraft wing housing that originally was designed to contain the non-HID landing and taxi lights in side-by-side relationship, is accomplished by installing an HID landing light, an HID taxi light and a power control device in the space originally designed to accommodate the non-HID landing and taxi lights. A single ballast provides power to both lamps which each comprise a housing, an HID bulb supported within the housing, a lens for passage of light from the HID bulb out of the housing, a primary reflector surface disposed behind the HID bulb, and a secondary reflector surface disposed in front of the bulb for reflecting light from the bulb back through the bulb for further forward reflection from the primary reflector surface through the lens. The lens may have a lenticular array including a plurality of cylindrical surface elements for spreading the light beam emitted by the lamp. An HID igniter may be located within the lamp's housing behind the reflector surface and electrically connected to the HID bulb.
Abstract:
A lamp for a vehicle, in particular for aircraft, has a housing in which a light source is arranged, with the housing including a first housing part detachably attached to a second housing part, the first and second housing parts being coaxially arranged. Each of the first and second housing parts has at least one projection extending in the axial direction from an edge thereof, for inter-engaging in a corresponding recess of the other housing part. Each projection has a retaining nose protruding in the radial, transverse, direction to form a groove into which a locking element can be inserted to lock the first housing part to the second housing part.
Abstract:
A lighting bracket assembly has a base, a lens holder, a retaining ring and a light housing. The base has a locking channel and a top edge radiused to define a first sphere. The lens holder is disposed within the locking channel and is adapted to provide upon installation of the assembly an external surface continuous with a surface defining an opening into which the assembly is installed. The retaining ring is fastened to the base and biases the light housing. The light housing comprises a back portion with an outer circumference and a plurality of curved wing members defining the contour of a second sphere concentric to the first sphere extending from the back portion along the outer circumference. The light housing is adapted to rotate through an angular range of up to 20 degrees upon application of force against the bias of the retaining ring.
