Abstract: A control set for adjusting the light source is provided. The control set includes a control module. The control module includes a control chip and a storage. The control chip controls the brightness of the lamp. The storage connected with a timing unit and stores a fine tuning signal. The fine tuning signal stored in the storage is generated and output to the adjust signal by turning off and turning on the adjustable power switch, the timing unit sets a preset time period in which the fine tuning signal maintains effective, and the fine tuning signal controls the lamp to have a brightness the same as the brightness when the lamp is turned off last time, or the brightness of the lamp is gradually increased to the preset brightness and then decreased.

Abstract: A light emitting diode (LED) emergency light with transportation mode includes an alternating current (AC)-direct current (DC) LED driving circuit, a light source, and an emergency module, wherein the emergency module includes a battery, the AC-DC LED driving circuit is electrically connected to a terminal of the light source, and the emergency module is electrically connected to another terminal of the light source. After the emergency module generates a transportation mode signal, the LED emergency light enters the transportation mode, and a power supply circuit within the emergency module utilizing the battery to drive the light source is turned off according to the transportation mode signal. Therefore, after the LED emergency light enters the transportation mode, current consumption of the LED emergency light is decreased significantly, so the present invention greatly extends storage time of the LED emergency light during a transportation and warehouse process of the LED emergency light.
