    摘要: A lens for a light emitting diode is formed with a material having a refractive index of n, and the lens includes a base, a first curved circumferential surface extending from the base, a curved center-edge surface extending from the first curved circumferential surface, and a curved centermost surface extending from the curved center-edge surface. The base includes a groove for receiving a light emitting chip therein. In the lens, a distance from a center of the base to a point of the curved center-edge surface is always shorter than the radius of curvature for the point of the curved center-edge surface. The curved centermost surface has a concave shape with respect to the base. In addition, when an obtuse angle formed between a main axis of the lens and a tangent line of a point of the curved centermost surface is A1, and an acute angle formed between a straight line linking the center of the base to the point of the curved centermost surface and the main axis of the lens is A 2, the lens satisfies the equation: A1+A2

    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.
