Patent number: 7021805Abstract: A translucent member is arranged so as to cause light originating from an LED light source oriented toward the front of a lamp to enter the translucent member. Outgoing LED light that has entered the translucent member is reflected rearward by a front surface, and then the light is reflected forward by a rear surface, to thereby exit forward of the lamp from the translucent member. At that time, an area on the front surface located in the vicinity of an optical axis Ax is formed as a normal reflection section subjected to reflection surface treatment. The other area of the front surface is formed as an internal reflection section which causes the outgoing LED light to undergo internal reflection. A plurality of reflection elements are formed on the rear surface of the translucent member so as to cause the outgoing LED light reflected from the front surface to enter the internal reflection section at an incidence angle which is smaller than or equal to a critical angle.Type: GrantFiled: July 2, 2003Date of Patent: April 4, 2006Assignee: Koito Manufacturing Co., Ltd.Inventors: Yasuyuki Amano, Yasuo Teranishi, Hiroya Koizumi

Patent number: 6811277Abstract: A vehicle lamp is constructed such that light exiting from an LED light source is converted into collimated light and such that the collimated light is reflected forward of the lamp by means of a reflector. At that time, the reflector portion has a stepwise reflection surface in which there are alternately formed a plurality of light incidence sections into which the collimated light enter and a plurality of intermediate sections into which no collimated light enters. Further, each of the intermediate sections is formed from an irregular surface formed so as to recess rearward of the lamp with respect to a plane parallel to the direction of radiation of the collimated light. By means of the irregular surface, stray light or the like included in the collimated light exiting from the optical member is reflected forward of the lamp. As a result, when the lamp is viewed from the front, the light incidence sections appear to glare, resembling spread spots, and the intermediate sections also appear to glare.Type: GrantFiled: July 10, 2003Date of Patent: November 2, 2004Assignee: Koito Manufacturing Co., Ltd.Inventor: Yasuyuki Amano
