Inventor: SASA MICHINARI
IPC: H01L33/32
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To improve the dielectric breakdown resistivity against inverse voltage. SOLUTION: A light emitting diode 110, which is formed by the III-group nitride semiconductor consisting of an n-conductor type high carrier density n<+> layer 3, a light emitting layer 5 and a p-conductive type p-layer 61, and a compensatory diode 320, having the same structure as above, are formed on the same sapphire substrate 1. An n-electrode layer 8 and the p-electrode layer 321 of the second layer 62 of the p-conductive type of the compensating diode 320 are connected. A p-electrode 7 and the n-electrode layer 322 of the first layer 3 of an n-conductive type of the compensating diode 320 are connected. At this point, even when inverse voltage is applied to the diode 110, i.e., even when the n-electrode 8 becomes higher than the p-electrode layer 7, inverse voltage is not applied to the light emitting diode 110 because the compensating diode 320 is conductive.  As a result, the breakdown by inverse voltage can be prevented.

Abstract: PURPOSE:To eliminate eccentricity and deformation of a lens and prevent deterioration of optical function by installing projecting parts in more than three places in the circumference inside a cylinder frame and retaining the outer periphery of the lens in a tight fit with tip of the projection part. CONSTITUTION:The outer periphery of the lens 1 is retained in a tight fit utilizing projections 2a of at least three or more points formed at equal angles within the cylinder frame 2. Because of this, even when variation in size between the two, or size change due to lapse of time after engagement due to environmental change such as temperature or humidity is generated, the outer periphery of the lens 1 and the projecting parts 2a inside the cylinder frame 2 are always fitted together without any opening between them. Furthermore, since the projection parts 2a are formed at an equal angle within the cylinder frame 2, the lens 1 receives force to match its center to the center of the cylinder frame 2, there is no eccentricity and the lens is retained in the specified position within the cylinder frame 2. Thus, the lens can be retained without eccentricity or deformation and the deterioration of the optical function can be prevented.
