Problems solved by technology

In this way, it is difficult to have a uniform lighting intensity throughout the space illuminated by the desk lamp
Direct sunlight can also easily cause glare
[0004] In addition, because the LED desk lamp itself is relatively large, it is difficult to move and carry the LED desk lamp

Embodiment Construction

[0024] Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

[0025] figure 1 A perspective view of an LED desk lamp according to one embodiment of the present invention is shown.

[0026] The lighting section 10 is a section in which a lamp is installed as a light source to perform a role of illuminating a site to be irradiated. The lighting part 10 includes a rotatable rotating part 1 and a fixed part 2 connected to each other through a rotating joint 3 .

[0027] Such as figure 2 As shown, the rotating part 1 including the LED and the reflective polarizing and scattering film can be rotated by the rotating joint 3, thereby adjusting the site to be irradiated in various directions. figure 2 The left figure of the figure shows the LED desk lamp according to the present invention, wherein the LED lamp of the swivel part 1 is inclined about 30 degrees with the bottom surface on which the LED desk lamp is placed...

Abstract

The present invention provides an LED desk lamp, comprising a lighting portion (10) including an LED and a reflective polarized and diffusing film and having a rotatable rotation portion (1) and a stationary portion (2), wherein the rotation portion (1) and the stationary portion (2) are connected to each other by a rotation joint (3); a first hinge portion (20) connected to the stationary portion (2) of the lighting portion (10); a support portion (30) connected to the first hinge portion (20); a second hinge portion (40) connected to the support portion (30); a stand (50) connected to the second hinge portion (40); and a bottom portion (60) connected to the stand (50), wherein the lighting portion (10) is rotatable based on the first hinge portion (20) as an axis, thereby forming an angle of 0 degree to 180 degrees with the support portion (30), and the support portion (30) is rotatable based on the second hinge portion (40) as an axis.

Description

technical field [0001] The invention relates to an LED desk lamp. Background technique [0002] Desk lamps are commonly used in offices, homes, and elsewhere to illuminate certain spaces. For conventional desk lamps, incandescent lamps or fluorescent lamps have been used. However, due to the properties of incandescent or fluorescent lamps, the lighting part should be within a certain size range, and there are limitations in the shape and design of the lighting part. Since a large amount of heat is emitted from the lamp as the lamp is continuously used, the material used to enclose the lamp is limited to aluminum or the like. Also, power consumption is high, and flickering of the lamp due to prolonged use causes eye fatigue. [0003] Therefore, recently, desk lamps using LED lamps instead of incandescent or fluorescent lamps have been developed. LED lights are closer to sunlight and can create various atmospheres. Also, the LED lamp can freely adjust light intensity and ...
