An aircraft headlight includes at least one visible light source for emitting a headlight light output; a light transmissive cover, at least partially covering the at least one visible light source; and at least one infrared emitter for emitting infrared radiation. At least 90% of radiation energy, comprised in the infrared radiation emitted by the at least infrared emitter, is emitted within a predefined wavelength range; and the light transmissive cover allows at least 25%, in particular at least 30%, more particularly at least 45%, of the radiation energy, which is emitted within the predefined wavelength range, to pass through the light transmissive cover.

In various embodiments, an optical unit is provided. The optical unit includes a first optics element which act as a lens and is made of silicone, and a second optics element. The second optics element is arranged in the first optics element that is formed from an at least one of harder or stiffer material as compared to the first optics element.

A headlight is disclosed, comprising a headlight body, a temperature sensor, an IR module, a low beam module, and a controller. The headlight body has a housing and a lampshade. The lampshade has a light-absorbing and heating layer. The temperature sensor is configured inside the headlight body, to detect the temperature of the lamp. The IR module is a wide-angle LED lamp, positioned inside the headlight body, and It directly irradiates toward the lampshade. The low beam module is configured inside the headlight body, emitting toward the lampshade, and an emitting direction of the low beam module crosses an irradiating direction of the IR module. The controller is electrically connected to the IR module and the temperature sensor, and turns on/off the IR module based on the temperature of the lamp.

The present invention concerns a lighting and/or signaling device (10) for a motor vehicle, said lighting and/or signaling device (10) comprising: a housing (1); an outer lens (3) designed to close the housing (1); at least one light module (5) housed inside said housing (1) comprising: at least one optical surface (9, 9′, 9″); at least one light source (7, 7′) interacting with said optical surface (9, 9′) to form a light beam; a heat sink (11) comprising a plurality of fins (13); an air flow generator (15) designed to generate an air flow (17) towards the heat sink (11), said air flow (17) passing through the fins (13) of the heat sink (11); and a light module holder (19) comprising a front part (20a) oriented toward the outer lens (3) with a plurality of gaps (21) designed to direct the air flow (17) coming from the heat sink (11) towards the outer lens (3).

A vehicle lamp has a lamp housing, a light-emitting device, a fan, and an auxiliary heater located within the lamp housing. The lamp housing has a lamp cover and an airflow circulating structure inside the lamp housing to form a circulation passage therein. The circulation passage corresponds to a main transmitting area of the lamp cover in position. Airflow, generated by the fan, inside the circulation passage is heated by the auxiliary heater and at least one light-emitting diode module of the light-emitting device. The main transmitting area is heated by heated airflow. Accordingly, the snow attached onto the main transmitting area are is removed rapidly and efficiently to let light emitted by the light-emitting device pass through the main transmitting area free from being blocked by the snow.
