A battery operated street lamp needs to have an optimised control mechanism for its operation in order to conserve the amount of energy that is being consumed by the lamp. The source of power that is provided to the street lamp is the battery that is available in the system. The battery is charged with the help of a solar panel, which stores energy in the battery during the daytime and it is used for operating the street lamp at night.
The batteries of the system are usually capable of operating the lamp during the nighttime but it is also important to conserve the amount of energy that is stored in the battery. This will help increase the overall operating time provided by the battery and the operating life as well.
Therefore, in order to optimise the operation of battery operated street lamp, experts have defined different working modes and control mechanisms as per the requirements of these modes. The working modes include light control, delay quenching, and delay plus low power.
Therefore, in order to properly operate the street lamp under these different modes, a control mechanism is usually designed so that the performance of the street lamp can be improved while the power stored in the battery can also be utilised in a highly efficient manner. In this article, we will discuss the three operating modes of the solar street life as well as the automatic control mechanism that is designed for the operation.
It is the normal operation mode of the battery operated street lamp. The full power is provided to the street lamp under normal working condition and the maximum storage of the battery is utilised under the circumstances. The light mode is usually turned on at the beginning of the operation of the street lamp when the battery capacity is at the highest and it is capable of supporting the full operation of the light for a greater period.
Similarly, the performance of the light mode of the street lamp is much higher as compared to other modes of light. It is usually desired that the battery of the street lamp is capable of operating at in the light mode for longer period so that better performance and value can be provided to the customers.
However, this street lamp might not be able to operate in the light mode since it drains the battery at a much higher rate due to which an automatic control mechanism is necessary, which can shift the lamp mode to delay quenching mode in case the battery level falls below a certain tolerance limit.
Delay quenching mode
The delay-quenching mode is more intelligent as compared to the light mode and it is capable of turning on or off the light depending upon the situation of the surrounding. The delay-quenching mode operates by analysing the presence of natural light in the atmosphere and turns on or off the light based on the data processing. Therefore, in this mode, the street lamp is off during the daytime because, under such circumstances, an ample amount of natural light is a present in the atmosphere.
However, when the sun starts to set then the natural light percentage in the atmosphere falls below a certain level. Under the quenching mode, the solar street lamp will be turned on until the natural light level does not reach the limit above which the light needs to be turned off. However, when the light level in the atmosphere starts to increase than in the quenching more, the solar street lamp will be turned off until it is not required to be turned on again. Therefore, this mechanism can be implemented with the help of an automatic control mechanism so that the efficiency of the use of the battery can be increased and its overall performance can be enhanced.
Delay plus low power mode
The delay plus low power mode is much more intelligent and efficient as compared to the light mode and light quenching mode. Under these situations, the street lamp is capable of making intelligent decisions and operating according to the requirements of the surroundings. Similarly, it is capable of analysing the level of the battery and regulate its output accordingly.
In this mode, there are three different operations in which the lamp can operate. The light turns on when the sun starts to set and the level of light in the atmosphere falls below a certain level. Initially, the operation of the battery operated street lamp is at its maximum capacity and it is drawing maximum power from the battery.
However, when the capacity of the battery falls below a certain level then the operation of the light shifts from full output to pulsed output. The lighting mode has a number of different benefits, as it is capable of providing a significantly large amount of light by utilising low power from the source.
Similarly, this mode also enhances the life of the illuminator as well as the battery and enables the street lamp to operate for a longer period. The light keeps on operating in the pulsed mode as long as there is a requirement for artificial lighting. When the sun starts to rise again and the natural light in the atmosphere starts to reach its normal level then the automatic control system of the battery operated street lamp turn it off.
In this way, the light operates in a highly efficient manner and the overall working efficiency and battery capacity of the system remain appropriate throughout the operation.
Battery operated street lamp: Conclusion
An automatic control system is capable of operating the street lamp in three different modes due to which it is capable of increasing the overall efficiency and performance of the system. Similarly, it utilizes the capacity of the battery in an intelligent manner and converses the energy for longer period operation. It is, therefore, recommended that street lamp may be provided with an automatic control system capable of operating in different modes and improving the overall performance.
