Abstract
Disclosed is a far-field target marker. Structural design of presently used markers is incapable of guaranteeing single peaks, smoothness and evenness of radiation wave beams, and hardly guaranteeing given radiation angles, and has no reinforcing design for sunlight effect elimination, high and low temperature resistance, radiation resistance and the like, and accordingly the marker can not adapt to requirements of far action distance and large range, and can not work normally under environments of wide change of high temperature and low temperature, and strong radiation. The far-field target marker comprises a tubular casing (1), wherein a high-evenness optical fiber panel (2) is assembled in the front section of the tubular casing, a lighting assembly is assembled on the rear section of the tubular casing and includes a circuit board (3), and a thermistor (4) and a set of far infrared light-emitting diodes (5) are connected onto the circuit board. The far-field target marker is used for marking active optical cooperative targets or active light sources, and is widely used in aviation field, aerospace field, airports, wharfs, transportation junctions and the like.
Description
Technical field:
The utility model relates to a kind of far field blip device.
Background technology:
Far field blip device, as a kind of distance range bigger active optics cooperative target or active light source sign, bigger than passive optical (target) marker operating distance scope, its light source multiselect is with light emitting diode (LEDs) at present, also has to select laser diode (LDs) for use.But, if light source is selected LDs for use, not only require complicated thermal control equipment, less stable, and, be difficult to satisfy requirement than the large radiation angle because of its angle of divergence is little.The light source of described far field blip device is selected LEDs/IREDs for use, do not need complicated Temperature-controlled appliance, advantage such as ensure easily that stability is high, the life-span is long, volume is little, in light weight and power consumption is few, and its angle of divergence size can select, and can ensure bigger operating distance scope.
Although there is series of advantages in the far field blip device of LEDs light source, according to present state of the art, still exist some major issues to need to solve, for example:

2. because far field blip device uses the LEDs/IREDs light source, and its radiant power is limited, even its light source uses 20～40 LEDs/IREDs, total radiant power also has only hundreds of mW, can't compare with the sunlight light intensity.Therefore, under common practical situations, the interference that how to suppress sunlight and other veiling glare just becomes the key issue that far field blip device will solve;
3. because the actual emanations wave beam of far field blip device is synthetic by the radiation beam of its all luminescent devices of light source, and the beam angle of formation is generally very big, even reach ± 90 °, be far longer than the angle of practical application scope, so just waste a lot of luminous energy.Therefore, how improving the concentration degree of its radiant power in the application point scope, promptly how to improve Effective Radiated Power, is the application problem that far field blip device must solve;
4. for far field blip device can be worked in adverse circumstances such as the gentle strong irradiation of height, at selected critical components such as luminescent device, need carry out Design of Reinforcement such as the gentle anti-irradiation of height, so that make marker can adapt to the variations in temperature of broad and stronger radiation environment.
Use at present the marker of LEDs light source, though have that volume is little, in light weight, power consumption is few and advantage such as the life-span is long, its structural design can not ensure the unimodal, level and smooth and symmetrical of radiation beam, also is difficult to ensure given radiation angle.Simultaneously, the radiant power of light source led s/IREDs concentration degree in marker application point scope is little, loss is big, do not eliminate effect of sunlight and Design of Reinforcement such as high-low temperature resistant, anti-irradiation, so can not the adaptation distance, requirement that scope is big, can not change operate as normal in broad and the strong radiation environment at the strong interference environment of sunlight and other veiling glare and at high low temperature.
