Abstract
The invention discloses an LED locomotive headlamp which comprises a high beam, a low beam and a marker light. The LED locomotive headlamp further comprises a front panel, a lamp shade, a mounting flange, reflectors, reflecting cups, LED lamp panels, radiators, holders, power sources and LED control and drive circuits. The lamp shades and the reflectors are connected with the front panel. The mounting flange, the reflectors, the reflecting cups, the LED lamp panels, the radiators, the holders, the power sources and the LED control and drive circuits are connected integrally. The LED light sources are adopted, the reflecting cups are used for secondary light distribution, and the light sources are long in service life and lower in power than tarditioanl light sources. The LED locomotive headlamp is applicable to subway and inter-city trains.
Description
Technical field
The present invention relates to a kind of locomotive headlamp, specifically a kind of LED locomotive headlamp.
Background technology
The China Transportation Industry development has obtained significant achievements, has supported the fast development of economic society effectively.Along with fast development of national economy, subway will become the main traffic in city.LED has advantages such as environmental protection, energy-conservation, life-span be long, has been widely used in every field.
At present, mostly the headlamp that uses on the locomotive is xenon lamp, the xenon lamp life-span is short, start moment need high voltage, power consumption is high, fault rate is high, often need repairing, and on locomotive, be not easy to change and safeguard.
So, need a kind of new technical scheme to address the above problem.
Summary of the invention
The objective of the invention is the deficiency to the prior art existence, a kind of new locomotive headlamp is provided, this locomotive headlamp adopts LED as light source, and the life-span is long, low in energy consumption.
For realizing the foregoing invention purpose, LED locomotive headlamp of the present invention can adopt following technical scheme:
A kind of LED locomotive headlamp; Comprise high beam, dipped headlights and identification light; This LED locomotive headlamp comprises panel, be installed on lampshade, mounting flange on the panel, be installed on panel inboard reflection shield, reflector, be installed on the reflector bottom the LED lamp plate, be installed on radiator on the LED lamp plate, be installed on fixed mount, power supply, LED control and drive circuit on the radiator; Said fixed mount is connected with bolt with radiator, and spring has been installed on bolt simultaneously; Power supply, LED control and drive circuit are given the switch transition between the power supply of LED lamp plate and control high beam, dipped headlights and the identification light.
Preferably, the LED lamp pearl that is provided with on the high-power constant-current circuit driving LED lamp plate is set.
Preferably, said radiator is the radiator that integral type anode melanism is handled.
Preferably, adopt the reflector of high light-emitting efficiency to carry out secondary light-distribution.
Compare with background technology, LED locomotive headlamp of the present invention adopts LED as light source, and the life-span is long, low in energy consumption; Adopt the reflector of high light-emitting efficiency that led light source is carried out secondary light-distribution; Can better control the rising angle of LED lamp, the headlamp thermal power is reduced, be convenient to the headlamp heat radiation; Mounting spring on the bolt, thus can carry out the fine setting of high beam, dipped headlights irradiating angle through the adjustment bolt.
