Rail train headlight with energy-saving function

technical field

The utility model relates to the technical field of lighting fixtures, in particular to a track train headlamp with energy-saving function.

Background technique

During the running of rail train vehicles, because they often have to pass through tunnels, the headlights on the front of the car will always be turned on, and due to the different terrain, elevated wires will also be set on the rail train's running route, which leads to During the day, the headlights are always on when the vehicle is driving on the elevated road, which causes energy waste.

Contents of the invention

The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a track train headlight with energy-saving function, which can automatically adjust the lighting brightness according to the brightness change of the surrounding environment.

The technical solution adopted by the utility model to solve the technical problem is: a rail train headlamp with energy-saving function, including a lamp housing, a transparent lampshade and a rear cover, and an LED light source for far and near light illumination is installed in the lamp housing. There is a reflector behind the LED light source, and the wiring harness that is connected to the power supply penetrates into the lamp housing from the back cover. The feature is that: the lamp housing is equipped with a photosensitive probe that senses the brightness of the surrounding environment, and the photosensitive probe is set far away from the LED light source. .

Preferably, a red tail light is installed in the light housing close to the LED light source, and the photosensitive probe is located on the light housing outside the red tail light.

In order to facilitate maintenance and replacement of lamps, an inspection cover is installed on the rear cover, and the driving power of the LED light source is arranged in the lamp housing on the back of the inspection cover.

Further, ventilating valves are installed at the corners of the back cover, and adjustment screws for supporting and adjusting the reflectors are provided on the corresponding mirror positions on the back cover.

The beneficial effects of the utility model are: the utility model arranges a photosensitive probe on the outer side of the lamp housing away from the LED light source, and uses the photosensitive probe to sense the brightness of the surrounding environment. When it is dark, the LED light source is fully illuminated, and when it is bright, the LED The light source is automatically dimmed to save electricity.

Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Fig. 1 and Fig. 2, a rail train headlight with energy-saving function includes a lamp housing 1, a transparent lampshade 2 installed on the front of the lamp housing and a rear cover 3 installed on the back of the lamp housing. An inspection cover 9 is installed on the cover 3 .

The right side of the lamp housing 1 is equipped with an LED light source 4 that satisfies far and near light illumination, and the left side of the lamp housing 1 is equipped with a red taillight 8 close to the LED light source 4. A reflector 5 is arranged behind the LED light source 4. The wiring harness 6 penetrates into the lamp housing 1 from the rear cover 3 , and the driving power supply of the LED light source 4 is correspondingly arranged in the lamp housing 1 on the back side of the maintenance cover plate 9 .

The lamp housing 1 is provided with a photosensitive probe 7 for sensing the brightness of the surrounding environment, and the photosensitive probe 7 is set away from the LED light source 4 . Specifically, the photosensitive probe 7 is located at the side of the lamp housing 1 outside the red tail lamp 8 .

The venting valve 10 is installed at the corners of the rear cover 3 , and the rear cover 3 is respectively provided with adjusting screw rods 11 for supporting and adjusting the front and rear of the reflector 5 at the positions corresponding to the reflector 5 .

As shown in Figure 3, a photosensitive probe 7 is designed in the lamp housing 1 of the headlight away from the LED light source 4. During driving, when the photosensitive probe 7 senses that the surrounding environment is dark (less than 20lx), the output is relatively low. A strong signal voltage is given to the chip, and the chip makes the power supply circuit of the LED light source 4 reach a 100% power state through program control, and the LED light source 4 emits brighter light; when the photosensitive probe 7 senses that the surrounding environment is brighter (higher than 20lx), Then output a weaker signal voltage to the chip, and the chip makes the power supply circuit of the LED light source 4 reach a 10% power state through program control, and the LED light source 4 emits darker light, thereby achieving the purpose of energy saving.

Inspired by the above-mentioned ideal embodiment according to the utility model, and through the above-mentioned description content, relevant staff can completely make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of this utility model is not limited to the content in the description, but must be determined according to the scope of the claims.
