Abstract
The utility model relates to an LED illuminating lamp for a locomotive, which comprises a lamp holder, an LED arranged on the lamp holder and a power supply circuit which is arranged on the lamp holder and is used for providing the power supply to the LED. The LED illuminating lamp for the locomotive can replace conventional fluorescent lamps and has high luminance, energy conservation and long service life.
Description
Technical field
The utility model relates to a kind of machine automobile-used LED lighting.
Background technology
The lighting that locomotive of the prior art is used is generally selected incandescent lamp or fluorescent lamp for use.Broken accident easily takes place in these lightings in the locomotive operation process, and power consumption is big, the life-span short.In addition, fluorescent lamp causes mercury pollution easily, is unfavorable for energy-conserving and environment-protective.
The utility model content
The technical problems to be solved in the utility model provides the machine automobile-used LED lighting that a kind of power consumption is less, service life is long.
In order to solve the problems of the technologies described above, the utility model provides a kind of machine automobile-used LED lighting, comprising: carry lamp body, be arranged on and carry the LED on the lamp body and be arranged on the power circuit that is used for providing to LED power supply that carries on the lamp body.
Described year lamp body is surface plate, and described LED is evenly distributed on a side of carrying lamp body, and power circuit is arranged on the opposite side that carries lamp body.
Lamp body was provided with transparent housing in described year.
Technique scheme of the present utility model has the following advantages compared to existing technology: machine automobile-used LED lighting of the present utility model can directly substitute traditional fluorescent tube, brightness height, energy-conservation and long service life and easy for installation.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the cut-away illustration of machine automobile-used LED lighting of the present utility model;
Fig. 2 is the front schematic view of machine automobile-used LED lighting of the present utility model.
The specific embodiment
Embodiment 1
See Fig. 1-2, the machine automobile-used LED lighting of present embodiment, have carry a lamp body 11, a plurality of being arranged on carried the LED3 on the lamp body 11 and is arranged on the power circuit that is used for providing to LED3 power supply that carries on the lamp body 11.
During use, the power end of power circuit links to each other with the locomotive dc source.
Carrying lamp body 11 is surface plate, and described LED3 is evenly distributed on a side of carrying lamp body 11, makes it luminous evenly, and power circuit is arranged on the opposite side that carries lamp body 11.
When electrical locomotive power was 110V or 75V direct current, described power circuit was a constant-current control circuit, and this constant-current control circuit links to each other with the locomotive dc source.
When electrical locomotive power was alternating current, described power circuit comprised: rectification circuit and constant-current drive circuit; The input of the rectification circuit car alternating current of meeting sb. at the airport, the power end of the output termination constant-current drive circuit of rectification circuit, the power end of the constant current output termination LED3 of constant-current drive circuit.
Constant-current drive circuit be smooth direct current electricity that rectification circuit is transformed into further conversion to be suitable for the luminous constant-current drive circuit of constant-current driving LED 3.
Present embodiment adopts machine automobile-used LED lighting service life is more than 20,000 hours; The LED luminous efficiency is high and energy-conservation, and LED brightness is more than 20000mcd.
The lighting angle characteristic of LED comprises 20 degree, 50 degree, 70 degree and 120 degree.
Described housing 10 adopts high-intensity PC plate polycarbonate structure plate shell to make, and also can adopt the material that other light transmissions are good, intensity is high to make.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
