1. Self powered lighting fixtures
A self powered lamp is a type of lamp with a built-in battery. Under normal power supply, the internal battery of the lamp will not supply power to the device. The battery will only supply power to the lamp when the power supply is lost. After the power is restored, the battery will stop supplying power, and the lost power source of the battery will gradually supply power to the battery during daily use, and it will stop when fully charged. This product is more suitable for customers in special occasions such as situations where there is no backup power supply or frequent power outages.
2. Assembled power supply lamp
The centralized power supply type lighting fixture does not have a built-in storage battery like the built-in power supply type lighting fixture, but is provided and controlled by an intelligent evacuation system for its power supply, Compared to the built-in power supply, it is easier to control because you can control the power size of the product, which can also achieve a saving effect. Unlike the built-in power supply lamps, which require continuous charging of the internal battery after use and extract appropriate power from the battery once the power supply is small, the integrated power supply lamps are more perfect in terms of saving and control. Centralized power supply lamps are more suitable for use in large areas with backup power sources. Once a power outage occurs, a backup power source will continue to provide power to the product.
Of course, using centralized power supply lamps also has a special function of automatic inspection when used in conjunction with intelligent evacuation systems. Because automatic power supply lamps are not easily controlled by intelligent evacuation systems, even automatic inspection is not perfect, The centralized power supply lighting fixtures, because the power supply and current intensity are controlled by the intelligent evacuation system, provide complete data for automatic inspection. This can greatly improve the reliability of the centralized power supply lighting fixtures, making many customers feel more at ease during use and reducing the maintenance workload of the lighting fixtures.
Each lamp needs to establish communication and inspection with the intelligent evacuation system during use, so each lamp needs to be connected by a line, Each lamp will generate a certain amount of current interference in the connection line with the system, and the line used for connection is not just a random choice because ordinary lines are prone to interference. Once disturbed, and all lines in one place generate a high level of interference, you cannot conduct inspections and communication, I recommend using twisted pair RS485 as the inspection and communication line to perfectly withstand the current interference between lamps. It is best to separate the lines when arranging the lines to minimize mutual interference.
