Abstract
The utility model relates to an LED vehicle light of a trolley locomotive. The LED vehicle light comprises a cast iron housing, flame-proof front and rear covers, explosion-proof glass and a metallic protective screen installed on the front cover, and a cable entry, tightened by bolts and arranged at the lower end of the housing. The LED vehicle light is safe when used in a mine where explosive and inflammable gases, such as methane gas, are present. The vehicle light comprises an LED light source and a constant-current switching power supply which directly converts DC 250V power supply into a DC 17V constant-current power supply to feed the LED light source. The vehicle light is safe, highly effective and electric saving and is long in service lifetime. A condensing lens is installed on the LED light source, and the illumination effect is excellent.
Description
Technical field
The utility model relates to a kind of LED car light, especially a kind of stringing formula motor LED locomotive light.
Background technology
At present, the locomotive light that uses in mine is mostly incandescent lamp, DC250V power supply by the stringing input drops to the DC24V power supply by DC converter, not only power consumption is large, illuminating effect is bad, and the life-span is short, easy damage, and changes inconvenient, time-consuming.
Summary of the invention
The purpose of this utility model be to provide a kind of energy-conserving and environment-protective, longevity, not fragile, change trolley locomotive LED car light easily.
Realize trolley locomotive LED car light of the present utility model, comprise cast iron housing, flame proof front/rear cover, explosion-proof safety glass and metal protective screen are housed in protecgulum, and the cast iron housing lower end is provided with the cable introducing device of bolted, can guarantee that locomotive light uses in the explosive occasion of gas is arranged.LED light source and constant-current switch power source are housed in described cast iron housing, and Switching Power Supply directly becomes the DC250V power supply of cable input the constant-current source supply LED light source of DC17V.Switching Power Supply adopts advanced integrated circuit, input power over-voltage and over-current no matter, all can export constant, assurance LED light source steady operation.Adopt collector lens above described LED light source, have advantages of that far firing range, light projector are effective.
The beneficial effects of the utility model are as follows:
Trolley locomotive LED car light of the present utility model adopts the illumination of LED lamp, has energy-saving and environmental protection, good illumination effect, long service life, the advantage such as easy for installation, has solved incandescent lamp, the Halogen lamp LED rapid wear is explosive, the difficult problem that need frequently change, waste time and energy.
Description of drawings
Fig. 1 is the structural representation of the utility model trolley locomotive LED car light.
The specific embodiment
Embodiment of the present utility model is as follows:
As shown in Figure 1, the utility model trolley locomotive LED car light comprises cast iron housing 1, flame proof protecgulum 2, metal protective screen 3, explosion-proof safety glass 4, LED light source 5, collector lens 6, constant-current switch power source 7, anti-explosion partition 8, cable entry 9, cable 10, flame proof bonnet 11.
The utility model trolley locomotive LED car light by constant-current switch power source, directly becomes the DC250V power supply into the DC17V constant-current supply, supplies with LED light source 5, has reduced DC converter, has greatly improved efficient, has improved service life, has saved the energy.Adopt collector lens 6 in LED light source, make LED locomotive light far firing range, light projector effective.In the processing of cast iron housing 1 and protecgulum 2, bonnet 11; designed square quick-fried faying face; and adopt explosion-proof cable entry 9; explosion-proof safety glass 4 and metal protective screen 3 are housed in protecgulum 2; car light can in being arranged, the inflammable and explosive occasion of gas be used safely; and protection LED locomotive light safety, make it not fragile.
