Dusk to dawn is the most popular operational profile in lighting applications. This is the old thinking of bundling lighting from the grid, because there is no worry about the use of electricity. Since there is a power supply, the grid lights can work normally, so there is no difference in cost. Adaptive lighting. With solar energy, adaptive lighting technology can be used to provide smaller illumination. Solar cell system.
The second popular system is the operation of a fixed hour or split time at dusk. For example, if a company closes at 10 pm and most people/customers leave before 11 pm, turning off the lights around midnight will reduce the size of the solar energy. If the same business is reopened at 6 am, the lights can be restored one or two hours before dawn, allowing the system to split time. The only time to turn off the lights is when no lights are needed. For safety reasons, during these shutdowns, the optical power can also be reduced to accommodate the lighting.
Other options include setting a real-time clock for a specific operating time. These systems run at night for a certain amount of time, then shut down, or they can be started again in the morning before dawn. These clocks are good for some applications, but it must be noted that they do not explain daylight saving time. This means that unless the show changes, the lights that are extinguished at midnight in the summer will only be illuminated until 11pm in the winter at 11pm.
If midnight is a required time, but it is ok at 1 am in the summer, the program that sets the system to midnight in winter will automatically run until 1 am in the summer. If you need more frequent changes, you can use a remote real-time clock to remotely install the clock.
Other actions include:
An electronic time computer for specific operations, programmable to 365 days, typically used for traffic flash, work shift programming, and other applications that require calendar control.
Motion activated infrared detectors or area of the occupancy sensor, the light only needs to be operated when there is someone in the area. These can bring illumination or reach different intensities during the activation period and then turn off or reduce the wattage for the rest of the time.
Switches, such as remote drive switches or spring loaded timers, only need to be blown at specific times or for short periods of time.
Each type of operational profile will be a factor in evaluating the correct solar component to operate the selected luminaire at the desired watt. Sometimes, looking at a project, there is a more fixed operating schedule, not just choosing dusk to dawn, you can decide or destroy a project. Use solar lighting experts to design the system.
