Abstract

The invention discloses an LED desk lamp. The LED desk lamp comprises a lamp holder, at least two lamp rods and lamp heads in one-to-one correspondence to the lamp rods and is characterized in that acontrol device, an infrared induction device, a transmission module and a power unit are arranged in the lamp holder; the lamp rods are evenly distributed around the lamp holder, the lower end of eachlamp rod is fixedly connected with the lamp holder, the upper end of each lamp rod is detachably connected with the corresponding lamp head, a transmission coil vertically winds around the upper endof each lamp rod, each lamp head is of a flying bird shape and comprises two ends, the first end of each lamp head is detachably connected with the upper end of the corresponding lamp rod, a receivingcoil vertically winds around the first end of each lamp head, and the second end of each lamp head is provided with an LED lamp panel. The LED desk lamp has the advantages that the desk lamp does notneed electric wires for power supply, the situation that the lighting effect is affected due to electric wire aging is avoided, the desk lamp can be automatically turned off when a user leaves, and energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to an LED desk lamp. Background technique [0002] Wireless power supply does not require any physical connection, and electric energy can be transmitted to the load at close range without contact. Specifically, it is a technology that transfers electric energy from a power generating device or a power supply terminal to a power receiving device without passing through an electrical conductor. Wireless energization mainly uses the principle of electromagnetic induction, and energy transmission is realized through energy coupling through coils. Generally, at least one transmitting coil and receiving coil are required. The existing coil generally circles horizontally around the center of the coil in circles on the horizontal plane where the center of the coil is located, resulting in a large volume of the transmitting coil. [0003] The existing LED itself has no radiation...
