摘要

PURPOSE: An LED lamp system is provided to improve heat dissipation properties without high efficient heat dissipation materials by individually forming an LED bulb and a DC power supply device. CONSTITUTION: An LED lamp(11) is turned on by DC power transmitted from an external DC power supply device(10). A battery(34) supplies charged power to the LED lamp and a socket(20). A lamp switch unit(13) includes a switch(14) and a first brightness control unit(15). The first brightness control unit includes a first brightness control means(16) to control the brightness of the LED lamp.
