Abstract
A lighting control system for controlling the illumination of street lighting comprising one or more light units L and one or more road located piezo strip P1, P2, where the detection of a vehicle by a road located piezo strip P1 activates one or more lighting units L, thereby only illuminating the lighting units that are actually required. Preferably the light units L control the illumination of street lights within a target area, and the lights may be deactivated via a timer after a suitable time period operated by a controller (Fig 2, C), or a secondary peizo strip P2 to act as an off switch. Two co-located piezo strips (fig 3) may be used to determine the direction of movement of a vehicle, to ascertain whether the vehicle is moving into or out of the target controlled area, and activate or deactivate the lights accordingly. The lighting unit may illuminate a quick start low efficiency bulb and/or slow start high efficiency bulb depending upon the illumination requirements.
Description
Piezo Strip Activated Vehicle Lighting System
Lighting units are controlled by timers or light detectors such that they are illuminated irrespective of whether a vehicle actually requires them to be on. This is unnecessarily costly to the providers of the lighting units.
To overcome this the present invention proposes the use of lighting units which are activated by means of piezo strips located in the proximity of the lighting units. The piezo strip acts as a switch which is triggered by the vehicle weight as it moves over the strip.
Use of this system will result in lighting units only being illuminated when they are actually required. This will result in energy cost savings to the provider of the lighting system.
This invention will now be described solely by way of example and with reference to the accompanying drawing in which:
Figure 1 shows the movement of an object causing a set of lights to be activated directly via piezo strips.
Figure 2 shows the movement of an object causing a set of lights to be activated using a controller.
Figure 3 shows the movement of an object causing a set of lights to be activated using a controller where the direction of movement is determined.
Automatic Detection of a Vehicle Approaching the Target Area
At Time=tl in Figure 1, 2 and 3 detection of the vehicle approaching the target area is made by means of the activation of the piezo road strip device PI.
The piezo strip P1 may be connected to a controller device C as shown in Figure 2 which receives vehicle detection signals from the piezo strip and consolidates multiple signals (e.g. from the front and rear wheels) into a single On’ signal which is sent to the lighting unit or a range of lighting units L. Consolidation is performed using the time delay between signals to indicate if the signals are from the same vehicle or not.
The controller may also be used in conjunction with a pair of co-located piezo strips as shown in Figure 3 where the time delay between activation of each strip is used to determine the direction of movement into the target area.
Alternatively the Piezo Strip may be connected directly to the lighting unit or range of lighting units and operate as a simple switch as shown in Figure 1.
Automatic Detection of a Vehicle Exiting From the Tar set Area
At Time=t2 in Figure 1, 2 and 3 detection of the vehicle exiting the target area is made by means of the activation of the piezo road strip device P2.
The piezo strip P2 is connected to the controller device C which receives the vehicle detection signals from the piezo strip and consolidates multiple signals to generate a single Off state as shown in Figure 2 or without the use of a controller as shown in Figure 1.
The controller may also be used in conjunction with a pair of co-located piezo strips as shown in Figure 3 where the time delay between activation of each strip is used to determine the direction of movement out of the target area.
Automatic Timeout
Alternatively instead of using a second piezo detector to generate an Off signal the lighting unit or a range of lighting units may be de-activated after a suitable preset timeout period either by the controller if present or directly by the lighting unit.
Claims (12)
1. A lighting unit control system where detection of a vehicle and subsequent lighting unit activation takes place by means of a road based piezo strip.
2. A lighting unit control system according to claim 1, in which a piezo strip detects the presence of a vehicle and activates a range of lighting units.
3. A lighting unit control system according to claim 1, in which a piezo strip detects the presence of a vehicle and de-activates a lighting unit.
4. A lighting unit control system according to claim 1, in which a piezo strip detects the presence of a vehicle and de-activates a range of lighting units.
5. A lighting unit control system according to claim 1, in which the lighting unit is deactivated after a suitable preset timeout period.
6. A lighting unit control system according to claim 1, in which a range of lighting units are de-activated after a suitable timeout period.
7. A lighting unit control system according to claim 1, in which a controller consolidates the multiple signals from e.g. the front and rear wheels of a moving vehicle into a single On’ or Off’ signal.
8. A lighting unit control system according to claim 1, in which a controller uses the time delay between signals from a pair of co-located piezo strips to determine the direction of movement of the vehicle.
9. A lighting unit control system according to claim 8, in which a controller uses the determined direction of movement of the vehicle into and out of the target area to automate the generation of On’ and Off signals sent to the lighting units.
10. A lighting unit control system according to claim 1, in which a lighting unit is activated and initially illuminates a quick start low efficiency bulb.
11. A lighting unit control system according to claim 10, in which a lighting unit is activated and simultaneous to the illumination of the quick start low efficiency bulb there is also initially illuminated a slow start high efficiency bulb.
12. A lighting unit control system according to claim 11, in which a lighting unit determines either by timeout or detection that the slow start high efficiency bulb is sufficient for illumination purposes and de-activates the quick start low efficiency bulb so as to just rely on the slow start high efficiency bulb for illumination purposes.
