LED aircraft observation lamp with automatic target correcting function

Abstract

The invention discloses an LED aircraft observation lamp with an automatic target correcting function, and relates to the field of LED illumination. The LED aircraft observation lamp comprises a fixing bracket and a main body shell which is of a bowl-shaped structure. According to the LED aircraft observation lamp with the automatic target correcting function, the structure is simple, installationand operation are easy, an LED is adopted as a light source, the working life can reach tens of thousands hours, and the later-period maintenance cost is greatly reduced; the LED aircraft observationlamp completely has no lamp filament breakage problem of a traditional observation lamp and better meets the requirements of the airborne environment; the power dissipation of the LED aircraft observation lamp can be reduced by about one fifth that of the traditional observation lamp; and TIR lens and a laser are arranged, therefore, the automatic target correcting function is achieved, the lightspot center can be easily found in the installation process, and the LED aircraft observation lamp can be aligned with a target irradiation area.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED aircraft observation light with a self-calibration target function. Background technique [0002] Observation lights are an essential external lighting source for every aircraft. Traditional observation lights are incandescent lamps with tungsten wicks. Although they have the advantages of mature technology and low price, their shortcomings are also obvious, as follows : A, short life, the working life of traditional incandescent observation lamps is very short, generally only tens of hours. B. Poor anti-vibration performance. The incandescent observation lamp uses a tungsten filament wick, and the tungsten filament in a high-temperature incandescent state is easily broken under the vibration and impact of the aircraft landing. C. The lighting effect is poor. The color temperature of the incandescent lamp is about 3000K, so the light color of the incandescent observation lamp ...

Problems solved by technology

[0002] Observation lights are an essential external lighting source for every aircraft. Traditional observation lights are incandescent lamps with tungsten wicks. Although they have the advantages of mature technology and low price, their shortcomings are also obvious, as follows : A, short life, the working life of traditional incandescent observation lamps is very short, generally only tens of hours

B. Poor anti-vibration performance. The incandescent observation lamp uses a tungsten filament wick. Under the vibration and impact of the aircraft landing, the tungsten filament in a high-temperature incandescent state is easy to break

C. The lighting effect is poor, the color temperature of the incandescent lamp is about 3000K, so the light color of the incandescent observation lamp is obviously yellowish, the lighting effect of the light source is poor, and it is easy to cause visual fatigue

D. There is no self-calibration function, because the index of the observation lamp requires its spot to be large and uniform, while the traditional observation lamp does not have a self-calibration device, so it is difficult to find the center of the spot and align it with the target irradiation area when installing the machine

To sum up, as a traditional incandescent lamp that has been used for a hundred years, continuing to use it as an aircraft observation light not only wastes precious airborne energy, but also has a short life, cumbersome maintenance, and low structural safety and reliability.

[0003] Chinese patent application CN201875543U discloses a xenon discharge aircraft observation lamp, including a glass cone, a glass screen, a ballast, and a xenon ionization lamp tube. The upper part of the glass cone is sealed with a glass screen, and a small dish is installed at the bottom. Welded inside the small dish, the outside of the small dish is welded with high-voltage insulated wires connected to the ballast, the inner surface of the glass screen has a grid, the xenon ionization lamp tube is located at the focal point of the glass cone, and the two ends of the xenon ionization lamp tube are respectively The set has a sleeve, and the sleeve and the pole are fixedly connected by a fixing belt. The advantage of this device is that it improves the light efficiency and the scattering range, but it has no self-calibration function. It is difficult to find the center of the light spot and align it with the target when installing the machine. Irradiation area
