Problems solved by technology

[0007] However, light emitting units using CCFLs have several disadvantages, such as high power consumption since power should always be applied to the CCFLs, low color reproduction efficiency (about 70% of that of a cathode ray tube (CRT)), and May cause environmental pollution due to the use of mercury

Embodiment Construction

[0047] Embodiments will be described below with reference to the drawings.

[0048] It will be understood that when an element is referred to as being 'on' or 'below' another element, it can be directly on / under the element, and one or more intervening elements may also be present.

[0049] Also, when it is mentioned that an element is located "on" or "under", "under the element" as well as "on the element" can be included based on the element.

[0050] Figure 1A and Figure 1B is a schematic view showing the light emitting unit according to the first embodiment. Figure 1A is the profile, and Figure 1B It is a perspective view.

[0051] Such as Figure 1A and Figure 1B As shown, the light emitting unit may include a light source module 100 having at least one light source 110 , a top plate 200 and a bottom plate 300 .

[0052] The light source module 100 having the light source 110 may be disposed between the top plate 200 and the bottom plate 300 and may be located ne...

Abstract

This paper discloses a light emitting unit and a lighting system using the light emitting unit. The light emitting unit includes: a top board; a bottom board; and at least one light source module located between the top board and the bottom board. The bottom plate includes a specular reflection area and a diffuse reflection area. The diffuse reflection area includes a first reflection pattern and a second reflection pattern, wherein the first reflection pattern reflects incident light through Lambertian distribution, and the second reflection pattern reflects incident light through Gaussian distribution.

Description

technical field [0001] Embodiments of the present invention relate to a light emitting unit and a lighting system using the light emitting unit. Background technique [0002] In general, representative large-screen display devices may include, for example, liquid crystal displays (LCDs) and plasma display panels (PDPs). [0003] Unlike a self-emitting PDP, an LCD basically requires an independent light-emitting unit due to the lack of self-emitting devices. [0004] Light emitting units used in LCDs are classified into side type light emitting units and vertical type light emitting units according to positions of light sources. In the side light emitting unit, the light sources are arranged on the left and right edges or the top and bottom edges of the LCD panel, and a light guide plate is provided to evenly distribute the light on the entire surface of the LCD panel, which ensures uniform brightness and enables the manufacture of extremely thin displays panel. [0005] V...
