Abstract

The utility model provides a flight safety collision avoidance light which characterized in that: power, linear constant current source, LED, constant voltage power supply, sudden strain of a muscle light controlling circuit including electricity connection each other, linear constant current source, LED and power are parallelly connected more than two the tunnel. The utility model aims at providing a flight safety collision avoidance light adopts LED emitting diode as the light source, controls with linear constant current source, reduction electromagnetic interference that can furthest, the multichannel is parallelly connected in order to guarantee normal work.

Description

A kind of flight safety anticollision beacon
Technical field
The invention relates to a kind of flight safety anticollision beacon, belongs to aviation and LED LED lighting and technical field of electronic control.
Background technology
Aircraft is when flight, and in order to ensure safety, to prevent, two machines from bumping against, it is necessary to the edge placement at airframe installs blinker light.With the locus of this labelling aircraft entity, it is called for short anticollision beacon.
In the past, this anticollision beacon adopted electric filament lamp or gas-discharge lamp.It is primarily present problems with:
1, luminous efficiency is low: the luminous efficiency of electric filament lamp only has 10 ∽ 20Lm/W；The luminous efficiency of gas-discharge lamp is about 50Lm/W；And the luminous efficiency of LED is more than 100Lm/W
2, service life is short: the service life of electric filament lamp is usually hundreds of hour；The service life of gas-discharge lamp is up to 3000 hours；And the service life of LED was more than 10000 hours.
3, reliability is low；Owing to electric filament lamp and gas-discharge lamp are all single lamp work, once damage, whole lamp both lost efficacy；And LED is multi-channel parallel, mutually independence, though Zhi Sheng mono-tunnel, also can normal operation.
Summary of the invention
For the deficiencies in the prior art, the purpose of the invention is to provide a kind of flight safety anticollision beacon, adopts LED light emitting diode as light source, is controlled with Linear CCS, it is possible to reduce electromagnetic interference to greatest extent；Multi-channel parallel is to ensure normal operation.
For achieving the above object, the invention is realized by techniques below means:
A kind of flight safety anticollision beacon, it is characterised in that: the power supply that includes being electrically connected to each other, Linear CCS, LED, regulated power supply, flashing control circuit, described Linear CCS, LED and power supply are two-way more parallel.
Further:
Described Linear CCS includes the control element, current sample, basis reference and the amplifier unit that are electrically connected to each other.
Described Linear CCS adopts six tunnels in parallel.
Described supply voltage is 28V.
Described regulated power supply is 12V.
Described current sample connects power cathode, and described LED connects positive source.
The invention provides the benefit that: a kind of flight safety anticollision beacon that the invention provides, and adopts LED light emitting diode as light source, is controlled with Linear CCS, it is possible to reduce electromagnetic interference to greatest extent；Multi-channel parallel is to ensure normal operation.
Accompanying drawing explanation
Fig. 1 is this utility model composition structural representation, and Fig. 2 is Linear CCS composition structural representation.
Detailed description of the invention
Below in conjunction with Figure of description, the invention is further described.
As shown in accompanying drawing 1,2, a kind of flight safety anticollision beacon, it is characterised in that: the power supply that includes being electrically connected to each other, Linear CCS, LED, regulated power supply, flashing control circuit, described Linear CCS, LED and power supply are two-way more parallel.
Further:
Described Linear CCS includes the control element, current sample, basis reference and the amplifier unit that are electrically connected to each other.
Described Linear CCS adopts six tunnels in parallel.
Described supply voltage is 28V.
Described regulated power supply is 12V.
Described current sample connects power cathode, and described LED connects positive source.
Technological difficulties of the present utility model: because LED is nonlinear device, it is necessary to adopt constant current source that it is powered.And constant-current source is divided into linear and the big class of switching mode two, it is contemplated that the airborne equipment strict demand to electromagnetic interference, we select Linear CCS.But, the efficiency of Linear CCS is low, power consumption big, heating is serious.For this, we by Selection parameter, carry out best coupling, it is ensured that temperature rise is within license.
The airborne power supply of 28 volts, through 12 volts of power module of voltage regulation, powers to flashing control circuit, thus, ensures the stable and accurate of control signal.
Six road constant-current sources are connected in parallel on 28 volts of airborne power supplies, power to respectively six paths of LEDs.
In Fig. 2,28 volts of power supplys are just sending into LED, after controlling the linear regulation of element, flow through current sample branch road, return to 28 volts of power supplys and bear.
From the current signal that current sample branch road obtains, send into the negative terminal of amplifier；And basis reference sends into the anode of amplifier.It controls to adjust process: when LED current increases, the numerical value flowing through current sample element also increases；Logical feedback, is added to the negative terminal of amplifier by signal, forms negative feedback so that it is controlled quentity controlled variable declines, and causes output electric current also to decline.When reaching basis reference, output remains unchanged.In like manner, when LED current reduces, control process contrary.Finally make current constant near reference value.
The ultimate principle of the invention, principal character and advantage have more than been shown and described.Skilled person will appreciate that of the industry; the design is not restricted to the described embodiments; the principle that the design is simply described described in above-described embodiment and description; under the premise without departing from the design spirit and scope; the invention also has various changes and modifications, and these changes and improvements both fall within the scope of claimed the design.The invention claims scope and is defined by appending claims and equivalent thereof.
