Description

{Multi-colored lighting device}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multicolor light emission illumination device, and more particularly, to a lighting device capable of realizing a wider variety of color temperatures and improved light uniformity.

Generally, an incandescent bulb has a filament type bulb that uses a fluorescent lamp using a fluorescent principle and a reflection of light by heat generation of a filament heated by an electric current. The filament-type bulb using heat generates too much heat, consumes a large amount of power due to heat loss, and the bulb is hot enough to be touched by hand. In addition, the fluorescent bulb or the triple-wavelength bulb using the fluorescent principle has a high luminous efficiency, but the voltage rising and discharging device necessary for high voltage to obtain the blinking energy by the light scattering using the fluorescent material inside and the light emission by the high energy transition Requiring a complicated power supply unit in the inside thereof.

Also, in addition to power efficiency, two incandescent lamps can not represent more than one color. The filament type bulb which is expressed in various colors is used for decorative purposes, but the bulb surface is coated with color or film. In this case, the color is uneven and the color is not clean. In addition, the fluorescent lamp mixes several fluorescent materials that produce color inside, but colors are too shallow and the number of colors is limited to a few.

Accordingly, in recent years, development of a light emitting diode (LED) having a relatively long life, high illuminance and low power consumption, and a bulb type LED lighting apparatus having a power source base so that a light source can be compatible with a conventional bulb socket It is actively being done.

Typically, a bulb-type LED lighting apparatus includes a lamp body that supports a LED light-emitting module and that serves as a heat sink for emitting heat generated from the LED light-emitting module, and a round- Cover.

However, when the LED is used for illumination, since it has a high luminance and a straightness that is not dispersed and diffused, it is not only narrow in the illumination range but also increases the eye fatigue, .

In recent years, reflector type, lens type, and vertical LED type LED lamps have been developed in order to improve the disadvantages of such LEDs and to provide a directing angle and light distribution characteristics similar to those of conventional incandescent lamps. However, the reflector type has a problem that the light efficiency is low, although it is easy to send the light to the rear portion of the LED which is the light emitting source. Although the lens type is higher than the reflector type LED lamp in terms of light control and light efficiency, it is technically difficult to implement the light-directing angle characteristic, and it is very difficult to transmit light to the rear side of the LED.

In the present invention, a multicolor light emitting device is disposed in one lighting device to realize various colors, and accordingly, a space in which the lighting device is disposed can be controlled to produce various moods in accordance with the multicolor light emitting device control.
