FIELD: electricity.
SUBSTANCE: invention relates to the field of lighting technology. The lighting device (10) comprises a light emitting diode (20), a transmitting base (50) comprising the luminescent material (51), and a translucent outlet window (60). The translucent outlet window (60) is located at a significant distance from the LED (20). The distance between the luminescent material (51) and the LED (20) of radar station is greater than 0 mm, and the distance between the luminescent material (51) and the outlet window (60) of radar station is also greater than 0 mm. The translucent outlet window (60) has an inlet face (63) with an area (AEW1) of the outlet window of the inlet face, and the transmitting base (50) has an inlet face with an area (ASI) of the transmitting base of the inlet face. The outlet window (60) and the transmitting base (50) have a surface area ratio of AEW1/ASI≥2.
EFFECT: achieving uniformity of the emitted light and increase in lighting efficiency.
