    摘要： A display device includes an optical module, a receiving container and a display panel. The optical module includes a substrate, point light sources and an optical lens. The point light sources are disposed on the substrate, each of which generates light using power applied thereto through the substrate. The optical lens includes a first lens part having a receiving part receiving each of the point light sources, a second lens part disposed at a peripheral portion of the first lens part and having a different shape from that of the first lens part, and a connecting part connecting the first and second lens parts. The light from each of the point light sources sequentially passes through the first lens part and the second lens part. The receiving container receives the optical module. The display panel displays an image using the light.

    摘要： A power supply includes a light source, a signal converting unit converting an externally supplied AC voltage into a DC voltage, a DC-DC converting unit converting a magnitude of the DC voltage, and a light source protecting unit. The light source protecting unit outputs the DC voltage of a predetermined range as a light source driving voltage to supply a stabilized source driving voltage to the light source and suspending an application of the light source driving voltage to the light source when a magnitude of the light source driving voltage is larger than a predetermined value, based on an externally supplied control signal.

    摘要： A light emitting diode includes a lens, a chip base attached to a bottom of the lens, and an LED chip attached in the chip base to be concentric with the lens. The lens includes a bottom, an outer sidewall extending from the bottom, a first outer top surface extending from the outer sidewall, a second outer top surface extending from the first outer top surface and having a substantially conical groove-like shape, an inner sidewall forming a side of a central cavity formed by hollowing a central portion of the bottom, and an inner top surface extending from the inner sidewall and forming a ceiling of the central cavity. The substantially conical groove-like shaped second outer top surface has an angular point formed toward the central cavity, and the inner top surface is convexly formed toward the bottom.
