Description

Dual power supply energy saving street lamp

technical field

The utility model relates to lighting equipment, in particular to a street lamp.

Background technique

Not only the number of street lamps is huge, but also the power of a single street lamp is large and the lighting time is very long. Street lamps consume a huge amount of electricity in the grid, which brings a huge burden to the grid power supply. In order to reduce the energy consumption of street lamps and reduce the burden on the power grid, some road sections have begun to use LED street lamps, thus achieving a certain energy-saving effect.

In order to further reduce the burden of street lamps on the power grid, solar LED street lamps are used in some road sections. Use solar panels to power LED chips to achieve lighting effects. In the case of relatively sunny weather, the electric energy provided by the solar panel can even provide all the electric energy for the LED chips to illuminate at night. However, in the case of bad weather, such as continuous cloudy and rainy days, the electric energy generated by the solar panel cannot fully meet the electric energy required by the LED chip for lighting at night.

The storage battery is used to store the electric energy generated by the solar panel and provide power for the ultrasonic transducer. When the power of the storage battery is lower than a set value, switch to power supply through the grid power supply system, and when the power of the battery is higher than a set value, switch to power supply through the solar power supply system. In this way, even in the case of bad weather, such as continuous rainy days, when the electric energy generated by the solar panels cannot fully meet the electric energy required by the light-emitting device, the power supply system for the light-emitting device can continue to be supplied with power.

The energy-saving street lamp with dual power supply also includes a road lamp control system, the street lamp control system includes an ultrasonic transducer and a signal processing system, the ultrasonic transducer is connected to the signal processing system, and the signal processing system is connected to a A light emitting device control module that controls the light emitting state of the light emitting device, the light emitting device control module is connected to the light emitting device.

When a pedestrian or vehicle passes through, once the pedestrian or vehicle on the road enters the detection range of the ultrasonic transducer, the ultrasonic signal received by the ultrasonic transducer will change, and the ultrasonic transducer will send a corresponding signal to the signal processing system. signal, the signal processing system sends a control signal to the light emitting device control module according to the received signal, and the light emitting device control module controls the light emitting device to light up, thereby providing road lighting for pedestrians or vehicles. Since the working state of the light-emitting device of the dual-power supply energy-saving street lamp is related to the passing situation of pedestrians or vehicles, it further effectively saves electric energy and reduces the load of the power grid.

The signal processing system has a delay function, which can control the light-emitting device to turn off after a period of time after being turned on. The delay function of the signal processing system can be realized by using existing technologies, and will not be described in detail here.

The signal processing system is provided with a signal oscillation module for adjusting the frequency of the ultrasonic signal. By adjusting the frequency of the ultrasonic signal, the anti-interference ability of the energy-saving street lamp with dual power supply can be enhanced.

There are two ultrasonic transducers, one for transmitting ultrasonic signals and one for receiving ultrasonic signals. The two ultrasonic transducers can be installed in the same housing to form a combination of receiving and sending. Its working principle is based on The Doppler effect of sound waves. The energy field distribution of the emitted ultrasonic waves has a certain directionality, and generally the energy field distribution is elliptical in the direction-facing area. The two ultrasonic transducers can also be placed on both sides of the road to form a receiving and sending type. The two ultrasonic transducers adopt non-directional transducers or semi-directional transducers. The non-directional transducer produces a hemispherical energy field distribution pattern, and the hemidirectional transducer produces a cone-shaped energy field distribution pattern.

The street lamp control system also includes a photosensitive element for sensing the intensity of external light. When the external light is strong, the street lamp control system turns off the ultrasonic transducer. And limit the lighting of the light emitting device to save energy, but it is not absolutely not allowed to light up the light emitting device. The photosensitive element plays the role of controlling daylight and nightlight, which can further save electricity.

The light emitting device control module is connected with a control switch. The control switch is preferably a remote control switch. Through the control switch, the working state of the dual power supply energy-saving street lamp can be artificially controlled to a certain extent, and the control requirements for the dual power supply energy-saving street lamp under special circumstances can be met.

Beneficial effects: due to the adoption of the above technical scheme, the utility model uses solar energy to supply power to the light-emitting device, even if the solar energy cannot supply power, it can also supply power to the light-emitting device through the grid power supply system; the use of ultrasonic technology further effectively saves power energy and reduces grid load.
