Shadowless table lamp capable of automatically adjusting brightness

Abstract

The invention relates to the technical field of LED lamps, and discloses a shadowless table lamp capable of automatically adjusting brightness. The table lamp includes a base, a fixing bolt is movablyconnected to the interior of the base; the right side of the base is movably connected with a connecting plate; the right side of the connecting plate is movably connected with a spring; a first rotating shaft is movably connected below the connecting plate, a supporting rod is movably connected to the right side of the first rotating shaft, a shaft sleeve is movably connected to the right side of the supporting rod, a second rotating shaft is movably connected into the shaft sleeve, a connecting rod is movably connected below the second rotating shaft, and a telescopic rod is movably connected below the connecting rod. According to the shadowless table lamp capable of automatically adjusting brightness, the LED lamp is used as a light source of the table lamp, glare is small, radiation is avoided, the working voltage is low, a direct-current driving mode is adopted, power consumption is ultralow, electro-optic power conversion is close to 100%, energy is saved by 80% or above compared with a traditional light source under the same lighting effect, ultraviolet rays and infrared rays cannot be generated, and the LED table lamp has the advantages of being environmentally friendly, energy-saving, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a shadowless desk lamp that can automatically adjust brightness. Background technique [0002] LED light is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. LED light source has low glare, no radiation, no harmful substances during use, low working voltage, DC drive mode, ultra-low power consumption, electro-optical power conversion close to 100%, and energy saving of more than 80% compared with traditional light sources under the same lighting effect. LED has better environmental protection benefits. There are no ultraviolet and infrared rays in the sp...
