Patent number: 8882319Abstract: An LED assembly according to an embodiment of the present invention may improve dark regions generated between LED chips by employing a first reflective layer between the LED chips. By employing a transparent optical layer or an optical layer including a scattering particle between an LED chip and a phosphor layer, direct contact between the LED chip and the phosphor layer may be avoided, thereby preventing a low light extraction efficiency. Further, by employing a second reflection layer on side surfaces of an LED chip, an optical layer, and a phosphor layer, a relatively high contrast may be obtained. An LED assembly may enhance contrast through a reflective layer while increasing light extraction efficiency by including a scattering particle in a phosphor layer.Type: GrantFiled: May 18, 2012Date of Patent: November 11, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Hee Dong Kim, Moo Youn Park, Soo Hwan Lee, Hee Seok Park

Publication number: 20140321140Abstract: The present invention is directed toward light module for a motor vehicle headlamp that has numerous light sources, a primary lens, and a secondary lens. The primary lens is configured to collect light emitted from the light sources, and to convert this light to an intermediate light distribution having the form of a closed, illuminating surface area. The secondary lens has an object-side focal length, and the primary lens and the secondary lens are disposed such that the intermediate light distribution lies, at a spacing of this focal length, in the beam path in front of the secondary lens. The light emission surfaces of the light sources are separated from one another by spacings lying between them, and the primary lens is configured to distribute the light emitted from the light sources such that the spacings in the intermediate light distribution can no longer be perceived.Type: ApplicationFiled: April 29, 2014Publication date: October 30, 2014Inventor: Matthias Brendle

Publication number: 20140321133Abstract: A lighting device for vehicles with a minimum of two light modules, each comprising a number of LED light sources for the generation of a first light function and a second light function. One light module is a basic light module and the other light module is a long-range light module. A first light source and a second light source are arranged in the basic light module, so that when the first LED light source is energized, a first partial light beam for the creation of a first light function is radiated. When both the second LED light source and the first LED light source are energized, a second partial light beam for the creation of a second light function is radiated. A first LED light source and a second LED light source may also be arranged in the long-range light module, so that when the first LED light source is energized, a first partial light beam for the creation of the first light function is radiated.Type: ApplicationFiled: April 29, 2014Publication date: October 30, 2014Applicant: HELLA KGAA HUECK & CO.Inventor: Martin Seipel
