Abstract
The utility model relates to the technical field of LED (light-emitting diode) light and the field of automated control, in particular to an LED lamp tube with an emergency dimming and lighting function. A built-in polymer lithium battery, a charging/discharging protection circuit and a circuit for dimming control in discharging are additionally arranged on the ordinary LED lighting lamp tube. When an external line can supply power normally, the LED lamp tube with the emergency dimming and lighting function is driven by external mains power for lighting, and the lithium battery is charged until the charging protection circuit detects that the lithium battery is fully charged. When the external line fails to supply power, the LED lamp tube with the emergency dimming and lighting function automatically changes to be driven by the built-in lithium battery for lighting, and the light brightness is started according to the preset value. For example, when the brightness of 30 percent is started, the working requirements of emergency lighting can be satisfied, and longer lighting time can be ensured by the lithium battery.
Description
Technical field
The utility model relates to the LED lighting technical field, and automation control area.
Technical background
Under the background that the worry of current global energy shortage raises once again; Energy savings is the important problem that we shall face future; At lighting field, the application of LED luminous product is just attracting common people's sight, and LED is as a kind of novel green light source product; Must be developing tendency in future, it be the novel illumination light source epoch of representative that 21st century will get into LED.
Summary of the invention
