The utility model discloses a self-adjusted and energy-saving thermal inductance eye protection desk lamp, comprising a switch, a control circuit and a lamp. The control circuit is connected to the lamp through a capacitance (C1), an inductance and a filter circuit which are in a serial connection in order. The filter circuit is reversely connected to a diode (DW) through a resistance (R1). A triode (BC) emitter electrode is in a serial connection with the resistance (R1) through a photosensitive resistance (GB). A triode (BC) collector electrode, a diac switch component, a triac switch controllable silicon component and a lamp are in a serial connection in order. The two ends of the capacitance (C2) are respectively connected to the triac BC collector electrode and the triac switch controllable silicon component. The two ends of a variable resistance (RX) are respectively connected to the triac BC emitter electrode and the capacitance (C2). The utility model has advantages of possessing high efficiency, long service lifetime and no radiation; saving electricity and energy; protecting environment and resisting explosion; having cold luminescence and wide application in various situations.
