The specific embodiment
The first embodiment of the present invention relates to a kind of tunnel sense light, this tunnel sense light comprises light source, driver, is arranged on the moving target sensor of the place ahead, light source position preset distance, light source is connected with driver with the moving target sensor and is connected, as shown in Figure 1.Wherein, preset distance can be beyond 50 meters, to that is to say, 50 meters in the place ahead, light source position positions in addition of moving target sensor setting.In the present embodiment, the moving target sensor can be connected with driver by wire.
Wherein, whether the moving target sensor is for detection of having through vehicle, and export corresponding control signal according to testing result to driver, driver is used for according to the control signal from this moving target sensor that receives, the power output that adjustment provides to light source, power output after the adjustment is the energy-saving illumination that presets without vehicle pass-through the time, and is having car to pass through the period, returns in advance the normal operation level.
Specifically, the moving target sensor is not when having detected vehicle and passed through, to the control signal of driver output expression energy conservation; Driver is adjusted the power output that provides to light source when the control signal that receives from the expression energy conservation of moving target sensor, the power output after this adjustment is in the low level of the energy conservation of presetting.The moving target sensor will be within the time of setting when having detected vehicle and pass through, and stops to the control signal of driver output expression energy conservation or to the control signal of driver output expression normal operation; Driver is stopping to receive from the control signal of the expression energy conservation of moving target sensor or during in the control signal of receiving from the expression normal operation of moving target sensor, the power output that provides to light source will be adjusted automatically, power output after this adjustment is in the illumination level of the normal operation of presetting, and keeps this normal illumination level within the time of setting.
Driver in this example is to be formed by the transformer of two power stages, relay assembly.Such as, as shown in Figure 2, tunnel illumination light fixture group (the being light source) parallel connection of per 5 meters or 10 meters, and be connected to a transformer high output terminal by the normally-closed contact of a normal open relay, transformer input termination is to power supply.Two voltage transformers have a low-voltage output end in addition, and this output is connected with relay normally open contact.The operation signal input of relay is directly linked the output of the mobile induction time-delay sensor of at a distance infrared (being the moving target sensor), and the input of sensor is received the power supply input.Infrared mobile induction time-delay sensor can be arranged on 60~100 meters, the place ahead, tunnel, when there not being vehicle to be in conducting state through out-of-date infrared mobile induction time-delay sensor, and the relay adhesive in the driver, voltage output end is connected to the transformer low voltage output.Illumination is in default low-power and drives, and saves power consumption.When having vehicle to enter the infrared inductor vision area, infrared mobile induction time-delay sensor has disconnected the operating current of relay, and output is connected to the transformer high-voltage output by normally-closed contact.Relay provides high-level power output to light source when receiving this control signal, driving light source carries out more high-intensity illumination.The sensor can keep dissengaged positions 30 seconds (or longer time).As entering without vehicle again, namely recover attracting state, so that returning to default low-power, illumination drives.
It is worth mentioning that the tunnel sense light in the present embodiment is when moving target sensor or relay fault, it arranges and can make light source be in all the time high-caliber illumination condition.Light source will be in the normal illumination state, to guarantee vehicle driving safety.
