Abstract
The utility model discloses an LED auxiliary illuminating lamp for a locomotive. The LED auxiliary illuminating lamp for the locomotive comprises a light transmitting cover, an LED light source, a lens, a power source and a lamp shell. Under driving of a power board, light emitted by the LED light source is distributed through the lens, and therefore emitted light of the lamp is made to meet the light intensity requirement of TB/T2325.2 for the auxiliary illuminating lamp. The LED auxiliary illuminating lamp for the locomotive achieves replacing of locomotive auxiliary illuminating light sources, the LED light source which is more saving in energy and efficient is used, on the basis that the requirement for light intensity of the TB/T2325.2 is met, the power is lower, the service life is longer, the starting time is short, and the LED auxiliary illuminating lamp can replace an existing tungsten halogen light source auxiliary illuminating lamp.
Description
Technical field

LED is very fast as new light sources development at present, although the outdoor illumination nearby of current locomotive also has the LED of use as light source, but mostly do not bring into play the feature of the efficient energy-saving of LED light source own, the large and increase that brings volume of power, or be exactly the requirement that can not meet the TB/T3235.2 that is correlated with completely.
Summary of the invention
The purpose of this utility model is to address the above problem, and a kind of LED assist illuminator for locomotive is provided, and this illuminating lamp, taking LED as light source, is realized and met the LED assist illuminator that TB/T3235.2 requires.
For achieving the above object, the technical solution adopted in the utility model is: comprise housing, the front portion of housing offers the light-source chamber of an end opening, and rear portion offers the power source cavity of an end opening; LED lamp plate with some LED lamps is installed in light-source chamber, the power supply being connected with LED lamp plate is installed in power source cavity; Light-source chamber and power source cavity are respectively by diffuser and bonnet sealing.
The sidewall of described light-source chamber is the cascade groove that the two-stage radius for diffuser and LED lamp plate are installed increases successively; Wherein, LED lamp plate is arranged on the center of housing front end face, is separately installed with lens on each LED lamp, and lens scioptics fixed head is fixed in the first order groove of housing front end face, and is assembled into an entirety with lens pressing plate; Diffuser is fixed on the second level groove of housing front end.
The quantity of described lens is 3～7.
After described lens and the assembling of LED lamp plate, the rising angle of lens is 4 °～8 °.
Described lens holder plate is fixed on housing by screw fastening.
Described power supply is arranged on housing rear end face; LED lamp plate is connected with power supply by bonding wire or cable, and the opening part of power source cavity offers the draw-in groove matching with bonnet power source cavity sealing.
The cross section of described shell is circular.
Described bonnet is circular or square.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is arranged on the LED lamp plate with LED lamp on the housing that offers light-source chamber and power source cavity, and the power supply of installation position LED lamp power supply in power source cavity, and whole illuminations is installed on locomotive, adopting halogen tungsten lamp and Xenon gas metallic halogen lamp illumination to change into conventional locomotive adopts LED light source to throw light on, therefore the utility model efficient energy-saving, can coordinate limit ring device to use, can not affect because of the requirement of stroboscopic properties of product and life-span simultaneously; To compare the life-span longer with halogen tungsten lamp and Xenon gas metallic halogen lamp, and power is less, and later maintenance cost is lower.
Brief description of the drawings
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is main sectional view of the present utility model.
Wherein, 1 is diffuser; 2 is lens; 3 is LED lamp plate; 4 is housing; 5 is power supply; 6 is bonnet; 7 is lens pressing plate; 8 is lens holder plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1 to Fig. 2, the utility model comprises that cross section is circular shell 4, and the front portion of housing 4 offers the light-source chamber of an end opening, and rear portion offers the power source cavity of an end opening; LED lamp plate 3 with 3～7 LED lamps is installed in light-source chamber, the power supply 5 being connected with LED lamp plate 3 is installed in power source cavity; Light-source chamber and power source cavity seal by circular diffuser 1 and circular or square bonnet 6 respectively.The sidewall of light-source chamber is the cascade groove that the two-stage radius for diffuser 1 and LED lamp plate 3 are installed increases successively; Wherein, LED lamp plate 3 is arranged on the center of housing 4 front end faces, is separately installed with lens 2 on each LED lamp, and lens 2 scioptics fixed heads 8 are fixed in the first order groove of housing 4 front end faces, and is assembled into an entirety with lens pressing plate 7; After lens 2 assemble with LED lamp plate 3, lens 2 rising angles are 4 °, 5 °, and 6 °, 7 °, 8 °; Diffuser 1 is fixed on the second level groove of housing 4 front ends.Power supply 5 is arranged on housing 4 rear end faces; LED lamp plate 3 is connected with power supply 5 by bonding wire or cable, and the opening part of power source cavity offers the draw-in groove matching with bonnet 6 power source cavity sealing.
