LED (Light Emitting Diode) light sources that are widely used in mobile phones, notebooks, monitors, TVs, etc., have recently attracted attention as applications for illumination. In recent years, a variety of lighting devices utilizing LEDs have been developed and used in terms of environmental pollution due to various color expressions, power consumption, long life, and performance improvement, as well as the prohibition of use of incandescent lamps.

 These LEDs are smaller than conventional light sources, have a long life span, and have a merit of low power and efficiency because electric energy is directly converted into light energy. Particularly, the power consumption is very low at 1/8 of the bulb and 1/3 of the fluorescent lamp, and the filament is not short-circuited like a bulb, and the lifetime is usually 50,000 to 100,000 hours, which is semi-permanent. Due to these characteristics, various lighting devices utilizing LED light sources will be researched and developed in the field of illumination in the future.

However, the LED lighting device using an LED light source having a single color temperature can not control the color temperature as the color temperature value is fixed at the production stage It has disadvantages. In order to set the LED illuminance and color temperature differently according to the installed place, environment, user's taste and demand, it is necessary to select and install an LED lighting device having a different color temperature according to the environment. In order to change the LED lighting device, It has a performance problem.

 In order to effectively realize such a color temperature control function, a white LED device and a technical method are disclosed in which a variety of color temperature expressions and color temperature can be controlled in Korean Utility Model Publication No. 10-0818162 and Registered Utility Model No. 10-1314130. In the method of the utility model, LED chips having different color temperatures are alternately arranged at the intervals in the same package body, and the third color temperature can be expressed by adjusting the illuminance of each LED chip.

In case of applying this method to actual products, the PCB and package should be separately designed to control the color temperature in the product production stage. In order to control the color temperature, the LED chip of different color temperature should be controlled so that the color temperature can be adjusted Resulting in inefficiency that the maximum illumination of the configured LED chip can not be used.

The object of the present invention is to solve the above-described problems, and it is an object of the present invention to provide a color display device capable of expressing a color desired by a user by adjusting the color temperature of the control light source unit, And it is an object of the present invention to provide a structure of an LED lighting device which can easily control a color temperature.

According to an aspect of the present invention, there is provided an LED lighting device including a current control unit for controlling a current to control a current, a main light source unit having one or more white LED lamps arranged therein, A light guide plate which is provided on the upper side of the main light source unit and is transparent or semitransparent to be fixed to the housing and which is capable of diffusing light, a light guide plate provided on one side or front side of the light guide plate And an adjustable light source unit in which one or more LED lamps capable of expressing at least one of RGB (Red, Green, Green, Blue, and Blue) and a power source unit are arranged.

According to the structure of the LED illumination device of the present invention as described above, the main light source unit as a main light source can be a single color of white, and the adjustment light source unit can be provided as a lamp capable of expressing RGB color, The color desired by the user can be freely controlled and expressed through the adjustment light source unit. In this way, it is possible to realize a variety of emotional lighting as well as a lighting effect that only illuminates the darkness, and by separating the main light source of a single color and the control light source capable of realizing the RGB color, it is possible to improve the efficiency of the manufacturing process, Can be improved.

FIG. 2 is a schematic configuration diagram of an LED illumination device which is easy to control color temperature according to an embodiment of the present invention

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the embodiment of the present invention illustrated in the following can be modified into various other forms, and the scope of the present invention is not limited to the following embodiments. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art.

FIG. 1 is a perspective view of an LED lighting device according to an embodiment of the present invention which facilitates color temperature control. The current control unit 10 for controlling the current and controlling the amount of light includes a power switch 11 for selecting connection and disconnection of a power source and a slider structure 11 for RGB (Red, Green, Blue, And a color temperature selector 12 for controlling the desired color temperature by controlling the degree of the color temperature. When the power supply switching unit 11 is turned on to supply power and the lighting is turned on, a lever having a slider structure capable of selecting the degree of each color of R (Red), G (Green), and B By manipulating, the degree of each color element can be controlled. For convenience, the reference initial value is white when all levers of R, G, and B are located at the center. By increasing or decreasing the color values of R, G and B, it is possible to manipulate the color temperature, that is, the color to change. The main light source unit 20 in which one or more white LED lamps are arranged is formed on the front surface of the reflective surface 21 having a concave structure for reflecting light. A housing 22 for protecting the illumination device from external impact forms the contour of the illumination device. The light guide plate 31 provided on the upper side of the main light source unit 20 and fixed to the housing 22 is capable of diffusing light in a transparent or translucent manner and is provided on one side or front side of the light guide plate 31 with RGB And an adjustable light source unit 30 in which one or more LED lamps capable of expressing at least one of red, green, green, blue, and blue are arranged.
