Abstract

The invention relates to a medium-intensity aviation obstruction light, which is provided with a lampshade, a lamp body, a lamp holder and a base. The lampshade is a cylindrical Fresnel lampshade, and the Fresnel lampshade is provided with a Fresnel For the lens, the refractive index of the Fresnel lens is 1.54-1.64, and the focal length of the Fresnel lens is 30-36 millimeters. The advantage of the present invention is that: the present invention is provided with a Fresnel lampshade, and the lampshade is designed according to a Fresnel lens. When the LED light source body is placed on the focal point of the lens, the emitted light is refracted by the lens and gathered into an approximately parallel light band. Eliminate light pollution, improve luminous efficiency, and have good uniformity; the power supply of the LED light source body in the base of the present invention uses multiple constant-current switching power supplies to supply power to the LED. The aluminum substrate where the LED light source is located is fixed on a specially designed heat dissipation profile, which effectively dissipates heat and prolongs the service life.

Description

technical field [0001] The invention relates to the technical field of aviation signal lights, in particular to a medium-intensity aviation obstruction light. Background technique [0002] Aviation obstruction lights are usually used in tall buildings, chimneys, iron towers and other high-rise buildings, and play a warning role during aircraft flight. [0003] At present, the traditional aviation obstruction light has almost no optical system or only a simple optical system, the light dissipation is large, the light utilization rate is low, and light can be seen in unnecessary places above and below, causing light pollution; traditional aviation obstruction lights are widely used Incandescent lamps, halogen lamps, and xenon lamps, these light sources have low luminous efficiency, high energy consumption, short life, and large volume and weight of the lamp body. Since aviation obstruction lights are installed at extremely high places, is the installation and maintenance c...
