Patent number: 9874662Abstract: An illumination device includes a light source, a device body to which the light source is mounted, and an optical member configured to control light distribution of light emitted from the light source. The light source includes LEDs arranged in a matrix form or a linear form. The optical member includes a lens portion configured to control light distribution of the LEDs on a row-by-row basis. The lens portion includes a recessed incidence portion on which the light emitted from the LEDs is incident, an elongated emission portion opposite to the incidence portion, and a pair of reflection portions which interconnects the incidence portion and the emission portion along a longitudinal direction thereof and totally reflects the light incident from the incidence portion.

Patent number: 9856021Abstract: An elongated lighting apparatus includes: a light source (linear light source); and an elongated optical component which transmits light emitted from the light source. The optical component has an elongated entrance surface where the light from the light source enters and an elongated exit surface where the light which has entered the entrance surface exits. The optical component includes light diffusers. Among the light diffusers, at least one of light diffusers disposed near a first end of the optical component diffuses the light from the light source, toward the first end side of the optical component more widely than (i) light diffusers disposed near a second end of the optical component do or (ii) light diffusers disposed near the center of the optical component do. The first and second ends, and the center of the optical component are in the longitudinal direction of the optical component.Type: GrantFiled: February 8, 2016Date of Patent: January 2, 2018Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Naotaka Hashimoto, Nobuyuki Matsui, Takashi Ohta

Patent number: 9849984Abstract: A lighting apparatus includes a plurality of LEDs arranged in a row on an elongated wiring board; and a lens covering all the LEDs and controlling distribution of light emitted from each LED. An optical axis of the light emitted from each LED is orthogonal to the wiring board. The lens has a light emitting surface that controls distribution of the light emitted from each LED. When the light emitting surface is divided into at least three regions, the lens performs light distribution such that light radiated from a region is distributed in a direction tilted with respect to the optical axis of the light emitted from the LED. Thus, asymmetric distribution of light is achieved when the optical axis of the light from the LED is the axis of symmetry, and further, the luminous flux in the direction tilted with respect to the optical axis is increased most.Type: GrantFiled: April 11, 2014Date of Patent: December 26, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Takashi Ohta, Tadashi Murakami

Patent number: 9815478Abstract: A driving assistance system includes a history storage unit, a behavior detecting unit, a state determining unit, and a notifying unit. The history storage unit stores a behavior history which is a past behavior history of a driver. The behavior detecting unit detects a current behavior of the driver.

Patent number: 9612516Abstract: A projection type image display apparatus (1) comprises a focus correction system (30). The system includes a temperature detection mechanism (16) for measuring temperature in the vicinity of a projection lens group (13), a correction amount calculation unit (18) for calculating a correction amount for correcting the focus shift caused by a temperature change, and a driving signal generation unit (19) for generating, based on the correction amount, a driving signal for driving a focus adjustment mechanism (15).
