Eye protection light-emitting diode (LED) desk lamp

Abstract

The invention relates to an eye protection desk lamp which comprises a lamp holder, a lamp rod and a lamp base. Two ends of the lamp rod are connected with the lamp holder and the lamp base respectively, a switch knob is arranged on the lamp base, a power wire and a plug which are connected with the switch knob are arranged at the bottom end of the lamp base, the lamp holder comprises an LED, a base, a spiral rod, a focusing device, a focusing base and an LED lampshade. The base is arranged on the LED lampshade, the LED is installed in a hole of the base, one end of the base is connected with the LED lampshade through a first connection key, the other end of the base is connected with the focusing device through a second connection key, the focusing device is located at the center of the LED lampshade, a spiral hole capable of being connected with the spiral rod is formed in the center position of the lampshade, and a cylinder under the focusing device penetrates the spring to be inserted into the corresponding hole of the focusing base. The desk lamp has the advantages that the trichromatic phosphor LED lamp is adopted, light is soft, the focusing device can adjust the condensed light brightness according to self requirements in real time, the height and the angle of the desk lamp can be adjusted by randomly bending the lamp rod, so that lighting can be provided for users in the optimum state.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an eye-protecting LED desk lamp. Background technique [0002] At present, for indoor lighting, there are two kinds of conventional desk lamps: one is an ordinary desk lamp, and the light source is an energy-saving fluorescent bulb. , the service life is short and relatively energy-consuming; the other is the LED desk lamp, although it is energy-saving, but if it is used for a long time, the focal length and concentration cannot be adjusted according to the needs of different users, which may easily cause eye fatigue and vision loss. The LED desk lamp that does not hurt the eyes is still waiting for further research. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an eye-protecting desk lamp with simple structure, convenient operation and soft light. [0004] The technical scheme of the present invention to solve t...
