Description

LED stand {LED STAND LAMP}

The present invention relates to an LED stand, and more specifically, to arrange a light guide plate having a predetermined thickness inside the upper and lower lamp covers, and to configure a lamp unit by arranging LED substrates equipped with a plurality of LED lamps on both sides of the light guide plate. The present invention relates to an LED stand for implementing indirect lighting through the light guide plate to reduce eye fatigue and at the same time slimming the thickness of a lamp unit to provide a stylish design.

In general, a floor lamp is used to brightly illuminate a limited area in an office or a home, and is widely used for precise work or learning.

Conventional floor lamps are mainly used incandescent lamps or fluorescent lamps, but recently, three-wavelength (RGB) lamps have been developed and applied that are environmentally friendly, provide almost the same amount of light as natural light, and provide low power consumption and long-term use. have.

Such conventional floor lamps provide only the ability to simply illuminate a limited area for the purpose of protecting the user's eyesight and for other purposes, thereby limiting the consumer's desire to purchase variety.

In recent years, the electric stand has been improved to the LED stand, which is closer to the sunlight, and various colors can be applied as a light source to create various atmospheres, and at the same time, the intensity of the light can be arbitrarily adjusted, and it is possible to save power without being affected by electromagnetic waves. A new concept of effective stand is being researched and developed.

However, the conventional LED stand is a direct lighting method in which an LED substrate equipped with a plurality of LED lamps, which are light sources, is installed inside a lamp cover and is irradiated through a protective glass so that most light from the light source is directly irradiated to the work surface. However, it is possible to obtain high illuminance with little power, but it is difficult to obtain uniform illuminance throughout the room, and it is easy to cause glare, and strong shadows due to light appear.

In addition, the conventional LED stand has a disadvantage in that the LED lamp is installed in a direct lighting (direct lighting) method inside the lamp cover through the LED substrate, the thickness of the lamp unit is made thicker than necessary, there is a limit to the stylish design.

In addition, the conventional LED stand has a disadvantage that the lamp unit installed through the pole in the support die is applied to the structure of three joints or less, so that the position control of the lamp unit is not easily performed by the user.

Therefore, the present invention was invented to solve the disadvantages of the prior art as described above, the problem to be achieved by the present invention is to arrange a light guide plate of a predetermined thickness with a reflective tape on one surface inside the upper, lower lamp cover, LED boards equipped with two LED lamps are arranged to correspond to both sides of the light guide plate to form a lamp unit, thereby implementing indirect lighting by the light guide plate to reduce eye fatigue and at the same time minimize the thickness of the lamp unit for a refined design. It is to provide an LED stand that can be provided.

Another object of the present invention is to install the lamp unit through the support die (POLE), but between the lamp unit and the pole by applying a two-joint structure via a tilting pivot means, between the pole and the support die By applying a two-joint structure through the rotation pivot means, to provide an LED stand to easily achieve the position control of the lamp unit.
