Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are describedbelow in order to explain the present invention by referring to the figures.
FIG. 1 is a front perspective view illustrating a display apparatus 10 according to an embodiment of the present general inventive concept. FIG. 2 is a front view illustrating a light source unit 50 and a light reflector 40 of the displayapparatus 10 of FIG. 1 according to an embodiment of the present general inventive concept; and FIG. 3 is a side sectional view illustrating the light source unit 50 and the light reflector 40 of the display apparatus 10 of FIG. 1 according to anembodiment of the present general inventive concept. The display apparatus 10 comprises a display part 15 to display an image thereon, a front cover 20 to surround a front surface of the display part 15, a side frame 70 to support the display part 15,and a rear cover 80 provided on a rear surface of the display part 15 to protect the display part 15. Additionally, a front mask 30 may be provided on a front surface of the front cover 20. The display apparatus 10 further includes the light reflector40 disposed at a bottom of the display part 10, a predetermined illumination target 45 disposed on the light reflector 40, and a power switch 60 disposed on the light reflector 40.
The plurality of light sources 51 are arranged on a lower part of the front cover 20 to emit light toward the illumination target 45 disposed in the light reflector 40 (described below). Here, the light sources 51 may be provided as a lightemitting diode (LED), however it should be understood that the scope of the present general inventive concept is not intended to be limited thereto. Other types of light sources may also be used. The light sources 51 may further comprise a straighttraveling supporter such as a reflecting mirror to guide the light to travel straight to the illumination target 45. Various numbers and/or colors of the light sources 51 may be used with the present general inventive concept according to a size of thedisplay apparatus 10. For example, the light sources 51 may include three or more light sources 51. Also, a driving substrate 55 may be provided to maintain an electrical connection with the respective light sources 51 and to supply power to therespective light sources 51 from outside to control the light sources 51 to emit light.
The light source supporter 53 supports the respective light sources 51 to control the light emitted from the light sources 51 to be emitted toward the illumination target 45. As illustrated in FIG. 2, if the illumination target 45 is disposed ona lower part of the display apparatus 10, two of the light sources 51 that are positioned on a far right and a far left of a light source arrangement may be inclinedly supported toward the illumination target 45. The light supporter 53 may be disposedbetween the driving substrate 55 and the light sources 51 as illustrated in FIG. 2.
Referring to FIGS. 2 and 3, the light source unit 50 may further comprise a light source support frame 59 to accommodate the light sources 51 and the light supporter 53, and to mount the light source unit 50 to the front cover 20. The lightsource support frame 59 may comprise an accommodator 52 to horizontally accommodate the light source supporter 53 which supports the light sources 51. The accommodator 52 may be provided as a guide which is vertically bent to a plate surface toaccommodate the light source supporter 53 and/or may be provided with a coupling hole to couple the light source supporter 53 and the light source support frame 59 using a fastener (e.g., a screw). A mounting part 57 may be provided on a first side ofthe light source support frame 59 to mount the light source support frame 59, which accommodates the light sources 51 and the light source supporter 53, to the front cover 20 of the display apparatus 10. The light source unit 50 may be provided on alower central part of the front cover 20.
A lens 56 may be provided between the respective light sources 51 and the light reflector 40 (described below) to collect or diverge the light emitted from the light sources 51. If the light emitted from the light sources 51 is divergent, aconvex lens may be provided to improve light collection toward the illumination target 45. If the light emitted from the light sources 51 propagates collectively, a concave lens may be provided to diverge the light, thereby making the light spreadsmoothly. Here, the lens 56 may be made of glass, plastic, etc., and may be mounted to the light source support frame 59 or may be integrally formed on the light source support frame 59.
The light reflector 40 may be provided across a lower side, a lateral side, or an upper side of the front cover 20. For example, as illustrated in FIG. 1, the light reflector 40 may be provided on the lower side of the front cover 20. The lightreflector 40 is provided with the illumination target 45 at which the light emitted from the light sources 51 is directed and collected. The light reflector 40 may be shaped like a curved plate to reflect the light incident on the illumination target 45in forward and downward directions. Alternatively, the light reflector 40 may be provided as an inclined plate. A surface of the light reflector 40 may be processed for better light collection and reflection. A predetermined mounting part (not shown)may be integrally formed on a first side of the light reflector 40 to mount the light reflector 40 to the front cover 20 or the side frame 70. Here, a position of the illumination target 45 is not limited to the lower side of the front cover 20, and maybe provided at various positions according to a desired external appearance.
The light source unit 50 may be mounted to the lower part of the front cover 20, and the light reflector 40 provided with the illumination target 45 may be disposed on a lower side of the light source unit 50. If the light sources 51 emit lightwith external power, the emitted light is directed to and collected on the illumination target 45 disposed on the light reflector 40, and is then reflected in the forward or the downward direction. Accordingly, the display apparatus 10 exposes light tothe front, thereby improving the external appearance overall.
A controller may be provided between the light sources 51 and the power switch 60 disposed on the first side of the light reflector 40 to control light emission of the light sources 51, thereby making the light sources 51 emit light when certainconditions are met. For example, the light sources 51 may emit the light when the display apparatus 10 is set to a power standby mode. For example, the light sources 51 may not emit light when the display apparatus 10 operates. When the power switch60 is turned off, the controller receives an off signal of the power switch 60, and controls power to be supplied to the light sources 51 to emit light, thereby indicating that the display apparatus 10 is in the power standby mode or off mode.
