Abstract
The utility model discloses a deflectable LED (Light Emitting Diode) locomotive headlamp, which comprises a support, a rotary lamp support, a lamp base, an LED bulb and lamp cover, a rotary step motor, a rotary transmission mechanism, a control box and a power box, wherein the LED bulb and lamp cover are arranged on the lamp base, and a radiating fan is arranged on the back of the lamp base; the deflectable LED locomotive headlamp is characterized in that the rotary lamp support comprises a horizontal plate and vertical lug frames on the both ends of the horizontal plate, a headlamp further comprises an elevation step motor, and the elevation step motor is arranged on the vertical lug frames of the lamp support. According to the utility model, one elevation step motor is added on the basis of the original headlamp, so that the headlamp can deviate vertically.
Description
Technical field
The utility model relates to the locomotive lighting engineering, but is specifically related to a kind of deflection LED locomotive headlamp.
Background technology
Along with behind the railway speed increase illumination in locomotive dead ahead being had higher requirement, and the illuminating lamp of original not enough 300m becomes one of weakness of advanced international standard locomotive of new generation.For this reason, many manufacturers have developed the Metal halogen lamp light source that can shine 800m.But this light source exists the life-span short, the deadly defect that poor reliability and electromagnetic compatibility are bad, for this reason; My company develops the locomotive headlamp of led light source of new generation, has overlong service life, and light efficiency is high; The locomotive headlamp that reliability is high is the inevitable substitute products of current locomotive headlamp.
Moreover, but existing deflection locomotive headlamp power supply and control section general with lamp holder apart from far away, the phenomenon that circuit can occur tiing a knot in the time of deflection, so that lamp holder can not deflection, is prone to cause the accident; In addition, existing locomotive headlamp generally has only left and right sides deflection, can not realize deflect, can only adjust the brightness of light and realizes through changing electrical current in the time of need making distance light-dipped beam adjustment.
Therefore be necessary prior art is improved.
Summary of the invention
In view of this; But the utility model provides a kind of deflection LED locomotive headlamp, adopts the LED bulb, and parts such as lamp holder controller, power supply are directly installed on the lamp socket; Shorten the line of lamp holder and controller, power supply; Guarantee the reliability of deflection, increase elevation angle deflection motor simultaneously, make head lamp can go up deflect.
The technical scheme that the utility model adopts is:
But a kind of deflection LED locomotive headlamp comprises support, rotary lamp frame, and lamp socket, LED bulb and lampshade, rotating stepper motor, rotating actuator, control box, power pack, said LED bulb and lampshade are installed on the lamp socket, and the said lamp socket back side is provided with radiator fan; It is characterized in that said rotary lamp frame is made up of the vertical ear frame at level board and level board two ends, said headlamp also comprises elevation angle stepper motor, and said elevation angle stepper motor is installed on the vertical ear frame of said lamp bracket.
Further; Said two ear framves top respectively is provided with the bearing of a position symmetry; Said lamp socket side is provided with two protrusion axles of position symmetry; It is inner that said protrusion axle is installed in said bearing, and lamp socket and rotary lamp frame are coupled together, and the output shaft of said elevation angle stepper motor connects the protrusion axle of said lamp socket.
Further; Said rotary lamp frame is installed on the said support; Said rotating stepper motor is installed on the level board of said rotary lamp frame; Said rotary lamp frame is installed on the said rotating actuator, and the output shaft of said rotating stepper motor connects the power transmission shaft of said rotating actuator, the output of rotating stepper motor is converted into the rotation of rotating actuator;
Further, said control box and power pack are installed in the gap location between said support and the rotary lamp frame, and said control box and power pack are electrically connected said rotating stepper motor and elevation angle stepper motor.
Further, the rectangular arrangement on said lamp socket of said LED bulb, or circular arrangement.
Locomotive obtains information such as bend that supervising device provides, tunnel, locomotive speed, current kilometer post; Calculate the angle that the locomotive headlamp is answered deflection according to these information then; To controller deflection angle is provided through communication module; Controller is controlled stepper motor again, thereby makes the locomotive headlamp make the deflection angle.Its effect is that the light light beam is followed the orbital curve illumination automatically.
The beneficial effect of the utility model is: adopt the LED bulb, advantage such as it is far away, energy-conservation to have an irradiation distance, and the life-span is long, and is easy to use; With power supply with controller is integrated is arranged on support or the rotary lamp frame, simplified wiring makes deflection more reliable and more stable.
