  • Publication number: 20140092599
    Abstract: A lighting device having a support module supporting LEDs and having an outer perimeter defining a curved portion, and a housing with an inner surface having a curved portion configured to receive the curved portion of the support module to enable the disk to be aimed, while the curved portions of the disk and housing remain in contact. Optional adjustment means facilitate aiming of the support module without the need to open the sealed LED module.

  • Publication number: 20120140458
    Abstract: A lighting device having a support module comprising a disk for supporting LEDs and having an outer perimeter with a curved portion and a housing with an inner surface having a curved portion configured to receive the curved portion of the support module disk so that the disk can be aimed by external adjustment devices with the curved portions of the disk and housing remaining in contact. The external adjustment device facilitates aiming of the disk without the need to open the sealed LED module. Heat from the LEDs and/or LED mounting assembly can be transferred via the contact of the curved surfaces to the outside air while the module is tilted, e.g., up to 15 degrees, or more, from vertical.

  • Publication number: 20100061097
    Abstract: Systems and devices are disclosed that can be aimed by external adjustment devices/features/means without the need to open the sealed LED module. Heat from the LEDs and/or LED mounting assembly can be transferred to the outside air while the module is tilted, e.g., up to 15 degrees, or more, from vertical. Additionally, the modular structure of the inground LED light can allow for upgrade/renewal of associated electronics with only minor disassembly. Moreover, the thermal dissipation/management afforded by the designs of embodiments can allow for an increase of the LED useful service life. The sealing of the inground light unit can preclude the chance of an end user (e.g., service technician) from causing the unit to leak and thereby cause premature failure.

  • Patent number: 6530676
    Abstract: A light fixture for outdoor use comprises a housing defining an interior space therein and having an open end. The housing interior space is configured for containing a lamp bulb to shine a beam out of the open end of the housing, and the open end includes a sealing face. A radial groove is formed in the housing proximate the housing open end, and includes a cam surface configured to slope in an axial direction along the housing. A retention ring is configured for surrounding the housing open end and is axially movable along the housing. The retention ring includes a retention surface configured to oppose the sealing face. A lens is configured to fit over the open end of the housing to close the housing and has an outer edge positionable between the sealing face and the retention surface of the retention ring for securing the lens to the housing.

  • Patent number: 5651606
    Abstract: The light fixture of the invention comprises a housing defining an interior space with an open end and a socket for supporting a lamp bulb to shine a beam out of the open end. A lens fits over the open end and closes the housing and the lens retaining ring engages the lens and secures the lens to the housing to seal the interior space. A plurality of drainage ducts are formed in the lens retaining ring and communicate with an outer face surface of the lens to receive and drain water away from the lens and prevent water accumulation and obstruction of the beam. A flange on the retaining ring cooperates with the housing to form a groove surrounding the open end which receives a glare shield ridge for securement of the glare shield without additional fasteners. Unique compression disks limiting sealing structure seal the open end of the housing as well as the housing interface with an adjustable arm.
