Abstract
The invention discloses a high protection LED (light-emitting diode) marker lamp which comprises a lamp body shell. An LED circuit board is arranged inside the lamp body shell, a lampshade is mounted at the front end of the lamp body shell, and a power wire connected with the LED circuit board is arranged at the rear end of the lamp body shell. An LED light source replaces a traditional tungsten halogen lamp and a traditional incandescent lamp, the protection level of the whole LED marker lamp is improved while illumination is achieved by the aid of the lampshade mounted at the front end of the lamp body shell, failure caused by water entering the marker lamp is avoided when a locomotive runs at a high speed, and running safety of the locomotive is ensured. In addition, as the service life of an LED lamp is not shorter than 20000h, the service life of the whole LED marker lamp is prolonged, and maintenance frequency is decreased.
Description
Technical field
The present invention designs a kind of LED identification light, relates in particular to a kind of high protection LED identification light.
Background technology
Identification light is the important component part of EMU and locomotive safety running, shows the light fixture of train working line and direction with red (or white) light.
The identification light of Modern High-Speed EMUs and locomotive and locomotive adopts halogen tungsten lamp and incandescent lamp more, because halogen tungsten lamp and service life of incandescent lamp are shorter.After the bulb scaling loss, need more change the bulb, for being convenient for changing, must adopt easy-to-mount structure.Domestic EMUs and locomotive indicating light require to be IP43, the requirement of external motor-car working standard UIC534-2002 and the unshielded grade of UIC532-1991 according to standard TB/T2325-2006.At present, domestic existing identification light can only be finished single red light and show, if use halogen tungsten lamp or incandescent lamp to want simultaneously integrated white light to show, need add in addition bulb or cooperate with another light fixture and finish, and structure is complexity.There are following shortcoming in halogen tungsten lamp and incandescent lamp:
Halogen tungsten lamp and service life of incandescent lamp that a, domestic EMUs and locomotive indicating light adopt are shorter, and parameter sees table 1(reference to standard TB/T2325-2006 for details).
Table 1
B, identification light degree of protection are excessively low.The standard UIC534-2002 that external motor-car identification light is commonly used and the requirement of the unshielded grade of UIC532-1991.It is that " this test should be simulated environment for use and be tested that protection test in the domestic railway standard TB/T2325-2006 requires.Light a lamp during test, because test product is charged, should take the electric shock-prevention safety measure.Test with portable trickle equipment, water temperature should remain on 5 ℃～25 ℃, and the time of drenching with rain is 10min, and hydraulic pressure is 10kPa ", according to standard to describe, the light fixture degree of protection is IP43.
The identification light that c, domestic EMUs use all can only carry out red light and show, if need simultaneously integrated red light and white light, needing increases light fixture and bulb, and prior art is difficult to carry out integrated.
Identification light is installed on and is positioned at EMU and locomotive and locomotive front center, and the procephalic switching mechanism non-tight of car structure.China's longitude and latitude span is large, and weather conditions are complicated, and domestic have a large amount of circuits to belong to long line operation, such as: military wide, Beijing-Shanghai, Guangxi etc., vehicle need to long line operation, identification light water inlet phenomenon will occur like this and cause the identification light fault, thereby affect car operation safety.The switching mechanism of CRH series EMUs and locomotive front end is not hermetically-sealed construction, and identification light may be intake when the operation of overall height speed, causes fault, thereby reduces vehicle operating safety.
Summary of the invention
The object of the invention is to address the above problem, a kind of high protection LED identification light is provided, this identification light adopts LED as light source, improves the degree of protection that structure improves lamp body integral body.
For achieving the above object, the technical solution adopted in the present invention is: the integrated light body case that comprises aluminum, the inside of lamp body shell is provided with the led circuit plate, and the front end of lamp body shell is equipped with lampshade, and the rear end of lamp body shell is equipped with the power line that links to each other with its inner led circuit plate.
Above-mentioned lamp body shell adopts fluid sealant to be connected with lampshade.
Above-mentioned lampshade adopts the PCF2000 that is mixed with diffusant to make.
Above-mentioned power line is connected on the led circuit plate of lamp body enclosure by the seal nipple of waterproof.
LED on the above-mentioned led circuit plate adopts adopting surface mounted LED to be welded on the circuit board.
Above-mentioned LED adopts ruddiness, high light white light and three kinds of LED SMD lamps of low light level white light pearl.
Compared with prior art, the present invention has following beneficial effect:
The present invention adopts led light source to replace traditional halogen tungsten lamp and incandescent lamp, by at lamp body shell front end lampshade being installed, when reaching illumination, improved the degree of protection of whole LED identification light, make locomotive when high-speed cruising, identification light can not cause because of water inlet fault, has guaranteed the safety of vehicle operating; In addition, because the LED light fixture is not less than 20000h service life, prolong the life-span of whole device, reduced the number of times of safeguarding.
Further, the material of lampshade of the present invention adopts PCF2000, and the inside is mixed with diffusant, can't observe inner LED bright spot when close-ups, and lampshade is connected with lamp body employing fluid sealant simultaneously, guarantees the IP grade of whole lamp.
Further, the LED in the led circuit plate of the present invention adopts adopting surface mounted LED to be welded on the circuit board, and this structure is positioned at the lamp body enclosure, does not affect the degree of protection of identification light.
Further, lamp body shell of the present invention adopts the integral type aluminum design, has further promoted the degree of protection of whole device.
Further, power line of the present invention is received in the lamp body shell by the seal nipple of waterproof, and the seal nipple degree of protection can reach IP68, so that water can not enter in the lamp body shell from here.
Further, the integrated ruddiness of the present invention, high light white light and three kinds of light of low light level white light at utmost satisfy the railway operation display requirement in one, and are simple in structure; Three kinds of different colours light are integrated in the same light fixture, do not need a plurality of bulbs even light fixture to finish same function.
