Abstract

The invention discloses a light emitting diode (LED) table lamp. The table lamp comprises a lampshade, an LED light source and a radiating hood, wherein the lampshade and the upper surface of the radiating hood form an obtuse angle; the LED light source is arranged at a joint between the lampshade and the radiating hood; at least one LED lamp bar is arranged inside the LED light source; the inside of the lampshade is provided with an inclined light guide plate of which one end is contacted with the upper surface of the radiating hood, and the other end is connected with a horizontal light guide plate; the other end of the horizontal light guide plate is contacted with the lower surface of the radiating hood; an included angle between the inclined and horizontal light guide plates is an acute angle; the light from the LED light source is sent between the inclined guide plate and horizontal light guide plate with reflection and refraction; bumps are uniformly formed on the inclined light guide plate; and the inclined and horizontal light guide plates are made of transparent organic glass. The LED table lamp has the advantages of convenient operation, soft illumination and no damage to eyesight.

Description

technical field [0001] The invention relates to a desk lamp, in particular to an LED desk lamp, which is particularly suitable for illumination of workbenches, desks or bedsides. Background technique [0002] Currently used desk lamps mainly include traditional desk lamps and LED desk lamps. Traditional desk lamps consume a lot of energy and flicker frequently, which does not meet the theme of energy saving and health in the world. However, most of the existing LED desk lamps are directly The point light source module used emits light, which is prone to glare. [0003] The Chinese patent authorization announcement number is CN2924285Y, and the authorization announcement date is July 18, 2007. The utility model discloses a kind of LED desk lamp. A lens body that covers the LED light source and has a light homogenizing effect. The lens body includes a light incident mirror and a light exit mirror. The light incident mirror and the light exit mirror are respectively located at...
