摘要： An aircraft light assembly comprises a light apparatus configured to be supported in a space on the body of an aircraft. The apparatus has one or more light emitting diodes (13) generating visible light and an outer structure overlying the LEDs. The outer structure includes a light transmission portion through which visible light from the LEDs can pass, and a metallic portion with an outer surface exposed to the external airflow. A heat-transmitting connection thermally links the LEDs to the metallic portion so that heat from the LEDs flows to the outer surface and is dissipated to the external airflow. The light assembly is configured to be secured in a conventional socket for an incandescent navigation light bulb and to receive the electrical current supplied thereto by the aircraft electrical system. Civilian applications of the unit have only visible LEDs. When the unit is for a military aircraft, it has electric circuitry connected with a visible light source and an IR light source, and the electric circuitry is configured to process the input current from the socket and based thereon operate in either a visible mode or covert IR mode. Where the current is in one electrical state, such as for example a certain voltage, the electric circuit sends power only to the visible light source. When the current is in a different electrical state, e.g., a different voltage level, the circuitry sends power only to the IR source, and no visible light is emitted. Different input current voltages or characteristics are also used to cause the IR emitter to flash in various patterns that can be programmed into the unit. All control may be accomplished over a single pair of wires, as in existing systems that do not have IR mode capability. To upgrade existing aircraft, light source units a shaped to fit in the apertures for existing lenses over incandescent navigational fixtures.

摘要： A dual mode light source unit (3) for an aircraft is configured to be secured into a socket for an incandescent navigation light bulb. The unit has electric circuitry configured to process the input current from the socket and based thereon operate in either civilian, visible mode or covert IR mode. When the current is in one electrical state, or a certain voltage level, the circuitry sends power to the visible light source (13). When the current is in a different state, the circuitry sends power only to the IR source (15). All control may be accomplished over a single pair of wires, as in existing systems that do not have IR mode capability. To upgrade existing aircraft, light source units (3) according to the invention are inserted into the existing navigational light sockets.

摘要翻译： 双模光源单元被配置为使得其可以被固定到飞机上的常规白炽灯泡插座中。 光源具有连接器部分，其适配在插座中并且接收由飞行器电气系统供应到其中的电流。 该单元还包括与连接器部分连接的电路和可见光源和IR光源。 电路处理来自插座的输入电流，并且基于此，以民用，可见模式或隐蔽IR模式操作。 在电流处于一种电气状态（例如一定电压）的情况下，电路向可见光源发送电力。 当电流处于不同的电状态，例如不同的电压电平时，电路仅向IR源发送电力，并且不发出可见光。 这样的系统允许现有飞机的现成升级，因为所有的控制可以通过一对导线实现，如现有的没有IR模式能力的飞机接线系统。 为了升级，根据本发明的光源单元可以简单地插入到现有的导航灯插座中。
