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

Patent number: 6811278Abstract: An electroluminescent clock is disclosed, wherein light emitting dots are installed on the back side of a transparent plate and ring around and beneath luminous markers, whereby when the light emitting dots are enabled, the luminous markers can be presented with uniform lighting to allow a user to see the clock time in the darkness and even from a distance. The night light feature is further enhanced by a special design that creates a soft visual effect on the dial of the clock for easy recognition of clock time.Type: GrantFiled: October 3, 2003Date of Patent: November 2, 2004Inventor: Yuan-Chi Sung

Patent number: 6811281Abstract: A board is made of translucent material and has two connecting plates formed on a side face of the board and a pattern formed on the board. A night light has five pairs of sockets adapted to connect to five plugs, two ears formed on opposite side faces of the night light to correspond to the connecting plates, a set of connecting pins formed on a rear side face of the night light to adapt for connecting to a wall outlet and a bulb received inside the night light. When the night light is connected to the wall outlet via the set of connecting pins, the bulb is lit to present the pattern of the board through the translucent board.Type: GrantFiled: May 5, 2003Date of Patent: November 2, 2004Inventor: Feng-Shen Hsiao

Patent number: 6811282Abstract: An improved straight down-type backlight module assembly structure is described. A groove is disposed in a base in a position that facilitates detachment. The groove is used to receive a light-emitting component. When the light-emitting component is to be maintained or replaced, it is not necessary to make many unnecessary detachment actions, hence facilitating detachment and maintenance of the light-emitting component.Type: GrantFiled: April 18, 2003Date of Patent: November 2, 2004Inventor: Heng Huang Kuo

Patent number: 6811283Abstract: A decorative illuminated artificial icicle assembly having a lamp housing having an open bottom end. An upright oriented elongated icicle-shaped body member has its top end detachably secured to the open bottom end of the lamp housing. The outer diameter of the icicle-shaped body member at its top end is less than the width of the open bottom end of the lamp housing to provide a light ray passage open space therebetween. A light source is mounted in the lamp housing. The lamp housing has a reflective inner surface that directs light rays downwardly into the interior of the top end of the icicle-shaped body member and also through the light ray passage open space to illuminate the outer surface of the icicle-shaped body member. The icicle-shaped body member may be tubular and have an aperture in its bottom for draining moisture that condenses therein. A colored lens positioned between the light source and the icicle-shaped body member can be used to vary the color of the illumination.Type: GrantFiled: April 17, 2003Date of Patent: November 2, 2004Inventor: Laszlo Kovacs

Patent number: 6811284Abstract: The invention is related to a method and apparatus for modifying the irradiation distribution of a radiation source. In accordance with the method the radiation source (1) is used to direct radiation to an essentially planar target surface (6). In accordance with the invention between the radiation source (1) and the target surface (6), several plates (4), which are essentially transparent to the radiation and have spaces between them, are placed close to the radiation source (1), in order to use the reflection and absorption of the transparent plates (4) to attenuate the radiation to desired areas.Type: GrantFiled: April 27, 2001Date of Patent: November 2, 2004Assignee: Endeas OyInventors: Jaakko Hyvarinen, Folke Stenman

Patent number: 6811285Abstract: Disclosed is a means and method for attaching an automotive lighting lens to the housing of an automotive lighting assembly while a structural adhesive cures. An automotive lighting assembly has a recessed hollow portion dimensioned to enclose one or more light fixtures and an open end with a peripheral edge. Formed around the periphery of the housing is a sealing groove and a plurality of engaging openings adjacent the groove. The engaging openings have a plurality of protuberances projecting into the opening, the protuberances providing a reduced area of clearance within the engaging opening. A covering lens has an exterior edge and a flange dimensioned to extend into and mate with the sealing groove formed around the edge of the lens.Type: GrantFiled: October 24, 2002Date of Patent: November 2, 2004Assignee: Guide CorporationInventors: Wendell G. Ferguson, Nova Filbrun, R. Andrew Kidd
