Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to an eye-protecting LED desk lamp capable of suppressing flicker. Background Art

[0002] LED (Light Emitting Diode), a light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. The semiconductor chip consists of two parts, one is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor, which is mainly electrons. But when these two semiconductors are connected, a PN junction is formed between them. When current acts on the chip through a wire, electrons will be pushed to the P area, where electrons and holes recombine, and then they will emit energy in the form of photons. This is the principle of LED light emission. The wavelength of light, that is, the color of light, is determined by the material that forms the PN junction. Traditional LED lamps use alternating current to power their light, and their brightness changes with the periodic changes of alternating current. Lamp flicker is caused by the change in brightness of light. Some flickers cannot be seen by people, but in fact they have caused harm to the human body and cannot meet the needs of people in modern society for LED lights.

[0003] In order to solve the above technical problems, the utility model designs an eye-protection LED desk lamp capable of suppressing flicker. The LED light bar is provided with a plurality of LED lamp beads. A light-smoothing plate, a blue light reduction plate and a light-uniform plate are provided in sequence between the LED light bar and the lower cover of the lamp head, which can make the light soft and not glaring, and effectively protect the user's eyes. A power interface is provided on the side of the base to facilitate power connection, and a baffle is provided on the base to assist in preventing placed items from slipping. A flicker suppressor is provided in the base, and the flicker suppressor is used for a constant desk lamp current, so that a stable current passes through the circuit board, completely avoiding flicker, making the light more uniform, and not causing harm to the eyes. In short, the eye-protection LED desk lamp capable of suppressing flicker has a reasonable structural design, is green and environmentally friendly, is highly efficient and energy-saving, and is safe to use.
