Abstract
The invention relates to a red and white LED (light-emitting diode) ceiling lamp of a cross-country vehicle. The ceiling lamp comprises a shell, wherein the back surface of the shell is connected to the top of a vehicle cab, the front surface of the shell is provided with a power supply switch, a left lens and a right lens, a PCB (printed circuit board) is arranged inside the shell, the PCB is welded with a red LED group and a white LED group, the red LED group is connected with a black-out lamp power line, and the white LED group is connected with an illuminating power line. The red and white LED ceiling lamp is simple in structure, under the normal condition, the white LED group is lightened for lightening the interior space of the cab, and under the emergent condition, the red LED group is lightened for playing an air raid warning effect. In addition, the light source of the ceiling lamp adopts an LED, so that the heat emission is small, the power consumption is low, the brightness is high, and the life is long.
Description
Technical field
The present invention relates to the lighting device of offroad vehicle, refer to particularly the red white dichromatism LED ceiling light of a kind of offroad vehicle.
Background technology
At present, white top light is only equipped with at automobile cab top, for the cabin space that throws light on.But offroad vehicle, in order to realize outside general lighting, also needs to tackle various emergencies,, except the white illumination lamp as general lighting, also need antiaircraft illuminating lamp.In addition, adopt bulb as light source for the ceiling light throwing light on, caloric value is large, and power consumption is high, and the life-span is short.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art and provide a kind of offroad vehicle red white dichromatism LED ceiling light, this ceiling light can be selected white illumination and red air defence warning as required, improves the performance of offroad vehicle.
The technical scheme that realizes the object of the invention employing is: the red white dichromatism LED ceiling light of a kind of offroad vehicle, comprise housing, the back side of described housing is connected in the top of automobile cab, the front of described housing is provided with power switch, described housing front is provided with left lens and right lens, in housing, be respectively equipped with left ceiling light with the corresponding position of described left lens and right lens fixing hole and right ceiling light installation fixing hole are installed, described left ceiling light is installed by fixing hole and right ceiling light installation fixing hole is drawn three hole plugs, described three hole plugs comprise antiaircraft power line, mains lighting supply line and ground wire, in described housing, be provided with PCB circuit board, on described PCB circuit board, be welded with emitting red light LED group and white luminous LED group, described emitting red light LED group is connected with described black-out lamp power line, white luminous LED group is connected with described mains lighting supply line, and described black-out lamp power line is connected with described power switch with mains lighting supply line.
In technique scheme, between described emitting red light LED group and automobile black-out lamp power supply, be connected with the first anti-reverse diode and the first current-limiting resistance, between described white luminous LED group and automobile lampet power supply, be connected with the second anti-reverse diode and the second current-limiting resistance.
In technique scheme, described power switch is located at the centre in described housing front, and described left lens and right lens are all connected on described housing by buckle.
In technique scheme, described left lens and right lens are all connected on described housing by buckle.
The red white dichromatism LED ceiling light of offroad vehicle of the present invention is simple in structure, has red, white two kinds of color LED lamps, is not only convenient to illumination, and can also be used for air defense illumination, is especially beneficial to and uses night.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of the red white dichromatism LED ceiling light of offroad vehicle of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is circuit theory diagrams of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As depicted in figs. 1 and 2, the red white dichromatism LED ceiling light of offroad vehicle, comprises housing 1, and the back side of housing 1 is connected in the top of automobile cab.The front of housing 1 is provided with power switch 3, right lens 2 and left lens 4, and power switch 3 is positioned at the middle part in housing 1 front, and right lens 2 and left lens 4 lay respectively at the right and the left side of power switch 3.Left lens 4 and right lens 2 are all connected on housing 1 by buckle, can be for convenience detach.Dismantle after left lens 4 and right lens 2, the inside is that two ceiling lights are installed fixing hole.Ceiling light afterbody is drawn three hole plugs 5, facilitates wiring, and three hole plugs 5 comprise antiaircraft power line, mains lighting supply line and ground wire.
As shown in Figure 2, in housing 1, be provided with PCB circuit board 6.On PCB circuit board 6, be welded with emitting red light LED group and white luminous LED group.As shown in Figure 3, emitting red light LED group is connected with antiaircraft power line, and white luminous LED group is connected with mains lighting supply line, and antiaircraft power line is connected with described power switch with mains lighting supply line.Between emitting red light LED group and automobile black-out lamp power supply, be connected with the first anti-reverse diode 7 and the first current-limiting resistance; between white luminous LED group and automobile lampet power supply, be connected with the second anti-reverse diode 8 and the second current-limiting resistance, for the protection of the safety of whole circuit.
The present invention lights white luminous LED group under normal circumstances, to illuminate cabin space; When emergency, emitting red light LED group is lighted, played air defence warning.In addition, light source of the present invention adopts light emitting diode, generates heat little, and low in energy consumption, brightness is high, and the life-span is long.
