Description

Color temperature variable COB module {COLOR TEMPERATURE VARIABLE TYPE COB MODULE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color temperature variable type COB module, and more particularly, to a color temperature variable COB module capable of radiating a warm white light source and a cool white light source in a radial manner to realize a minute color temperature.

Recently, customized lighting products have been launched with the focus on maintaining optimal tone names so that students can learn more efficiently by using LED as a light source based on the effect of brightness and color temperature on the brain waves and psychological state . This is due to the fact that unlike conventional fluorescent lamps, LED lighting can change the color temperature. For example, blue light with 7600 ~ 8000 Kelv (K) is related to the repair area, and blue light with 4200 ~ 4600 Calvin Lighting and art are known to be the most effective red light of 2200 ~ 2600 Calvin.

As described above, the method of implementing the emotional illumination using the LED to adjust the color or brightness of the illumination according to the taste or the characteristic of the user can be roughly divided into two.

First, there is a method of modulating the three types of LEDs of red, green, and blue (blue) and varying the color temperature of the white light to be mixed by changing the current applied to each LED (refer to Korean Patent No. 0825989) There is a method in which an LED chip emitting different colors is mounted in one package (refer to Korean Patent Publication No. 2009-0014615).

Second, as shown in FIG. 1, two kinds of LEDs are modularized by modulating the LEDs of a warm white light source (10: warm white) and a cold white light source (20: cold white light source) to vary the color temperature of white light There is a way.

However, the first method has the advantage that a wide range of color temperatures can be changed and implemented, but there is a disadvantage that a driving circuit for adjusting a specific color temperature is complicated.

In the second case, the color temperature is varied by using two color temperatures. For example, if only the on white light source 10 of 3000 K and the cold white light source 20 of 6000 K are arranged to operate only the on white light source 10, the implementation of 3,000 K and the operation of only the cold white light source 20, 1, the conventional LED module 1 is configured such that the on-white light source 10 and the cold white light source 20 are formed in a stripe pattern, as shown in FIG. 1, There is a problem in that it is difficult to realize a minute color temperature because the light source and the light source may cross each other.

It is an object of the present invention to provide a COB type LED module which is manufactured using an on white light source and a cool white light source, and is capable of displaying natural lightness and achieving a fine color temperature. a color temperature variable COB module in which a warm white light source and a cool white light source are disposed.

In the meantime, other objects not mentioned in the present invention will be further considered within the scope of the present invention which can be easily deduced from the following detailed description and effects thereof.

The color temperature variable type COB module according to the present invention includes an on white light source 10 and a cold white light source 20. The on white light source 10 and the cold white light source 20 are radially And the on-white light source 10 and the cold white light source 20 cross each other.

The color temperature variable COB module according to the present invention is arranged so as to intersect a plurality of radial areas formed from the center of the on-white light source and the cold white light source so that the on-white light source and the cold white light source spread out from the center of the module. Representation and fine color temperature can be realized.

1 is a view showing the arrangement of a warm white light source and a cold white light source of a conventional LED module.
FIG. 2 is a diagram illustrating the arrangement of an on-white light source and a cold white light source of a color temperature variable type COB module according to an exemplary embodiment of the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS The objects, particular advantages and novel features of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. Also, terms used are terms defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user operator. Therefore, definitions of these terms should be based on the entire contents of the present specification.

It should be noted that, in adding reference numerals to the constituent elements of the drawings, the same constituent elements are denoted by the same reference symbols as possible even if they are shown in different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In describing the components of the present invention, the terms first, second, A, B, (a), (b), and the like can be used. These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements. When a component is described as being "connected", "coupled", or "connected" to another component, the component may be directly connected or connected to another component, Connected ", "coupled ", or" connected. &Quot;

Hereinafter, the configuration and operation of an embodiment of the present invention will be described in detail with reference to the drawings.

First, FIG. 2 shows a layout of a color temperature variable type COB module according to the present invention. 2, the color temperature-variable COB module 100 includes an on-white light source 10 and a cool white light source 20, and includes a white light source 10 and a cold white light source 20. [ Circles (20) are arranged so as to intersect with a plurality of radial regions formed from the center.

FIG. 1 is a view showing the arrangement of a warm white light source and a cold white light source of a conventional LED module. 1 and 2, the conventional LED module 1 is arranged such that the on-white light source 10 and the cold white light source 20 are crossed in a straight line so that a stripe pattern is formed. On the other hand, The color temperature variable type COB module 100 according to the embodiment includes a white light source 10 and a cold white light source 20 radially arranged from the center of the module, alternating with each other one by one.

As compared with the conventional LED module 1 having a straight pattern as described above, according to the embodiment of the present invention, the plurality of on-white light sources 10 and the plurality of on- Since the light source of the cold white light source 20 spreads out from the center, there is no sense of disconnection between each of the on white light source 10 and the cold white light source 20, so that natural lightness and minute color temperature can be realized.

In addition, although not shown in the present embodiment, the on-white light source 10 and the cold white light source 20 may be arranged so as to form a complex crossing shape such as a spiral line shape as well as a radial shape like a dart- have.

In addition, as described above, when the on-white light source 10 is operated at 3,000 K and the cold white light source 20 is operated at a color temperature of 6,000 K, 3,000 K is realized And the cold white light source 20 can be used. If the on white light source 10 and the cold white light source 20 are all driven, the intermediate value 4,500 K can be driven. In addition, the color temperature-variable COB module 100 according to an exemplary embodiment of the present invention may adjust the color temperature of the white light source 10 and the cold white light source 20 to 3,000K to 6,000K The value of < / RTI >
