Patent number: 9488362Abstract: An LED lighting fixture including a housing comprising a single-piece wall structure defining a cavity with an LED-supporting surface therewithin. An LED illuminator is mounted at the LED-supporting surface in the cavity, the LED-supporting surface positioning the LED illuminator in a desired orientation. An LED driver may be secured against the housing which transfers heat therefrom. There may be a plurality of spaced apart LED illuminators mounted at the LED-supporting surface within the cavity. The LED lighting fixture may also include a single-piece reflector comprising a plurality of reflector cups for the LED illuminators and extending therefrom to a common forward end of the housing.Type: GrantFiled: June 27, 2014Date of Patent: November 8, 2016Assignee: Cree, Inc.Inventors: Kurt S.

Patent number: 9243793Abstract: An LED lighting fixture including a one-piece housing portion having a hollow interior cavity defined by a substantially planar interior backwall surface and a surrounding wall extending therefrom to a forward edge. An LED illuminator is on the substantially planar interior backwall surface, a backwall being a heat sink for transferring heat away from the LED illuminator during operation. A one-piece reflector member extends forwardly from the backwall interior surface and substantially across the housing portion to the surrounding wall. The reflector member has a reflector cup and an outward flange secured with respect to the surrounding wall at the forward edge thereof. The reflector cup defines an aperture configured and positioned such that the LED illuminator is exposed therethrough.Type: GrantFiled: January 29, 2014Date of Patent: January 26, 2016Assignee: Cree, Inc.Inventors: Kurt S.

Publication number: 20150226416Abstract: What is disclosed is a high power LED lighting fixture. It includes a light source enclosure for holding a LED lighting component and an electric enclosure for holding a power supply component; a front end of the electric enclosure being connected to a distal end of the light source enclosure, a heat isolation gap is defined between a front end surface of the electric enclosure and a distal end surface of the light source enclosure. The electric enclosure and light source enclosure are designed separately. A heat isolation gap is provided between the connection location of the electric enclosure and light source enclosure, thus increasing thermal resistance and reducing heat transfer between the power supply component and LED lighting component.Type: ApplicationFiled: April 24, 2015Publication date: August 13, 2015Applicant: CASTER LIGHTING INC.Inventor: Frank Tsao

Publication number: 20140085904Abstract: The invention discloses an LED light fixture, which comprises a lamp body and a lamp handle connected therewith, wherein the lamp body adopts an AC (Alternating Current) LED as a light source. As the LED light fixture does not need a power supply, the light fixture has the advantages of being small, having a simple structure and saving materials; as a plurality of small planes are used for forming a complete multi-stage sagittal reflecting surface, the light fixture has higher reflection efficiency; as a gland strip and a shielding mechanism are adopted, the reverse side of the product has a complete structure and is lightproof; as non-through screwed connection holes are formed at positions of the lamp body, at which the lamp body is connected with the lamp handle, the light fixture has superior sealability and watertightness.Type: ApplicationFiled: November 19, 2012Publication date: March 27, 2014Applicant: CASTER LIGHTING INC.Inventors: Frank TSAO, Yanchao HU

Patent number: 7934860Abstract: A lighting fixture includes a light unit, a supporting frame pivotally coupling with the light unit, and an angle adjustment arrangement including a first gear member provided at the light housing, and a second gear member provided at the supporting arm. The first gear member has a first teething face to match and engage with a second teething face of the gear member. When the first gear member is moved apart from the second gear member, the light housing is adapted to pivotally move with respect to the supporting frame so as to selectively adjust the projecting angle of the light unit. After the projecting angle of the light unit is set, the first gear member is moved back to re-engage with the second gear member to lock up the light unit at the projecting angle.Type: GrantFiled: April 3, 2009Date of Patent: May 3, 2011Inventor: Frank Tsao
