Abstract
The utility model relates to a full-colour LED locomotive signal machine, which comprises a casing, a lamp cover, and a plurality of groups of indication mechanisms. The utility model is characterized in that each group of the indication mechanism is composed of a color lamp, a voltage stabilizing circuit, and a sensing sampling circuit, and the color lamp is of single color, bicolor, and mixing color, and after being connected in series by the LED light emitting diodes and being sealed into the hemispherical shape through the epoxy resin, every two color lamps are connected in parallel to be a group; the sensing sampling circuit is composed of a sampling resistor, a current limiting resistor, an infrared illuminator, and a receiving tube. The utility model has the function of automatically detecting the sensing sampling and can be used in various types locomotive such as internal combustion, steam, electric, etc.
Description
The utility model relates to the railway signal device, particularly a kind of panchromatic LED engine man's indicator.
Engine man's indicator of the prior art is owing to adopt filament lamp as signal source, thereby has following deficiency:
1. lack service life, the mean life that producer provides is 1000 hours;
2. locomotive operation time vibration is bigger, causes filament easily broken, the caducous phenomenon of lamp holder;
3. anti-power-supply fluctuation is poor, easy burn-out more when particularly using on steam vehicle;
4. brightness, colourity are influenced by power-supply fluctuation, instability;
5. go out to put in storage automated watch-keeping facility and locomotive operation recording instrument though cab signal has been installed additional in the department that has now on signal,, make and install the sampling device difficulty additional owing to be subjected to the restriction of structure space, and the cost height.
The purpose of this utility model is to provide that a kind of good stability, fault rate are low, the panchromatic LED engine man's indicator of reliable operation, long service life.
Above-mentioned purpose of the present utility model can realize by such technical scheme: promptly a kind of panchromatic LED engine man's indicator, comprise shell, lampshade and some groups of indication mechanisms, it is characterized in that: every group of indication mechanism is made up of colored lights, mu balanced circuit and sensing sampling circuit, wherein, colored lights is monochromatic, double-colored and colour mixture, after the series connection of LED light-emitting diode, become semisphere through epoxy encapsulation, per two colored lights parallel connections are one group; The sensing sampling circuit has sample resistance, current-limiting resistance and infraluminescence and adoptor to constitute; One end of the output termination of mu balanced circuit colored lights in parallel, the current-limiting resistance of another termination sensing sampling circuit of colored lights in parallel.
The embodiment of the indefiniteness that said structure of the present utility model can provide by accompanying drawing further specifies.
The utility model has following accompanying drawing:
Accompanying drawing 1 is a structure External view of the present utility model;
Accompanying drawing 2 is schematic circuit diagram of the present utility model;
Accompanying drawing 3 is the connection diagram of the inner LED pipe of colored lights of the present utility model;
Accompanying drawing 4 is the structure birds-eye view of colored lights;
Accompanying drawing 5 is the lateral plan of colored lights structure;
Accompanying drawing 6 is the structural representation of bi-colour light.
Referring to accompanying drawing: panchromatic in the present embodiment LED engine man's indicator, comprise shell 1, lampshade 2 and 6 groups of indication mechanisms, wherein: every group of indication mechanism is made up of colored lights, mu balanced circuit and sensing sampling circuit, colored lights is monochromatic, double-colored and colour mixture, after 12 LED light-emitting diode series connection, becoming diameter through epoxy encapsulation is the hemisphere of 10mm, and its bottom has a permanent seat 3, and connection lead 4 is drawn by the bottom; Two colored lights parallel connections are one group; The sensing sampling circuit has sample resistance R15, current-limiting resistance R14 and infraluminescence and adoptor 3CU to constitute; One end of the output termination of mu balanced circuit colored lights in parallel, the current-limiting resistance R14 of another termination sensing sampling circuit of colored lights in parallel.
Mu balanced circuit of the present utility model can adopt accurate adjustable reference power supply WL431 that constant working power is provided.
Monochromatic burner of the present utility model adopts monochromatic LED light-emitting diode.
Bi-colour light of the present utility model adopts two kinds of colour light emitting LED light-emitting diodes each half, and is added with dividing plate 5 in the centre.
Colour mixture lamp of the present utility model is that white lamp adopts blue, yellowish green LED light-emitting diode to adopt the mode of mixed light to constitute.
Principle of work of the present utility model is such: mu balanced circuit provides constant working current to colored lights, and when guaranteeing that electrical locomotive power changes between 30--70V, colored lights still can normal operation, and brightness, colourity are constant.The sensing sampling circuit is when the colored lights normal operation, and the infraluminescence pipe is luminous, just offers each detecting device after being received by photodiode and makes sensing sampling usefulness, otherwise do not have sampled signal output.
The advantage that the utility model has owing to described structure is apparent: namely it adopts Take the full color LED tube core as light source, the color of colored lights is complete true to nature, and has adopted stable work Technical measures such as voltage, thereby prolonged service life, average life is greater than 30000 hours, Have adapt to that the voltage change scope is big, the advantage of brightness and chroma stability owing to have automatically Detect the sensing sampled functions, on the class type locomotives such as internal combustion, steam, electric power, all can use, its Advanced, practicality all is better than the at present incandescent lamp engine man's indicator of use, can be used as desirable The engine man's indicator regeneration product.
