A lighting system and components are described for a lighting assembly, including a socket (44, 46) having a socket body and an electrical connector (50) with a seal (60) in the socket to seal around a light source (42). The socket (44) is preferably configured to be independent of the mounting arrangement (40) for the lifting assembly. An insulator (94) is also disclosed for a lamp such as a fluorescent lamp having a body which protects the contact on the lamp so as to form a recessed lamp conductor. The combination of a socket and lamp insulator is also disclosed. Additionally, a lighting assembly (36) is disclosed incorporating the insulator, socket and mounting arrangements.

A voltage regulator circuit is described which includes a circuit input (48) and a circuit ouput for coupling to a load (74). A circuit interrupt element (82) is coupled between the input (48) and the load (74) for breaking the circuit between the input (48) and the load (74). A sensing circuit (76) between the input (48) and the output senses when a signal applied to the load (74) exceeds a defined limit. A trigger circuit (72) coupled to the sensing circuit (76) causes the circuit interrupt (82) element to trip when the sensing circuit (76) senses a signal which exceeds the defined limit.
摘要:
One aspect of the invention features a refrigerated display case door (12) that includes a hinge rail (18), a panel assembly (20), and a handle (16). The hinge rail (18) includes a channel portion and a hinge receiving portion. The panel assembly includes two panes of glass bounding a sealed space between the panes, and includes a first edge disposed within the channel portion of the hinge rail. The handle (16) is secured to a surface of the panel assembly proximate a second edge of the panel assembly opposite the first edge. The sealed space is closed by a peripheral seal disposed between the panes along a periphery of the panes. The peripheral seal includes a first material extending along a first portion of the periphery and a second material extending along a second, different portion of the periphery, where the second material is more transparent to visible light than the first material.

A controller (300) for trimming power used by a heated glass temperature-controlled storage device (100) comprising a frame (102) and a door, the door comprising a door rail (106) and a glass pane (104), wherein the glass pane (104) includes a glass heater circuit (208), the controller (300) comprising a variable impedance (302); a first impedance (304); a low pass filter (306); a diode for alternating current (DIAC) (308); and a triode for alternating current (TRIAC) (310), wherein the controller (300) is configured to adjust voltage from the AC power input (312) to a first voltage; filter the first voltage; generate a gate current when the DIAC (308) is on; generate a glass current when the TRIAC (310) is on; and provide the glass current to the glass heater circuit (208) when the TRIAC (310) is on, wherein the variable impedance (302) is adjusted so power used by the glass heater circuit (208) is below a first predetermined value.
摘要:
A door assembly that includes a single glass unit having at least first, second and third panels, a front surface, a rear surface, and an outside edge. At least one of the first, second or third panels is a transparent LCD panel on which media can be displayed. The single glass unit also includes a frame that at least partially surrounds the outside edge of the single glass unit, and electronic components in electrical communication with the LCD panel.
摘要:
Perimeter frame rails (36, 38, 40, 44) and door (234) frame rails are described for a more thermally efficient and cost-effective display case such as for refrigerated display cases (20). The frames (36, 38, 40, 44) are preferably formed from cold rolled steel. A perimeter frame may include first (66), second (68) and third (76) walls defining an opening or a recess (78) that can be closed by a contact plate (34). A door (22) for a refrigerated display case (20) may include a glass unit (398) and a forward portion extending inwardly from a perimeter frame edge portion toward an edge of the forward glass pane (236) and a first side portion extends rearwardly to a groove. An insulating member (258) insulates the door rail from the cold area and includes a portion engaging the groove. A glass door (22) is also provided for a refrigerated display case (20) having a first glass panel (420), a second glass panel (428), and low emissivity coatings on the inside surfaces of the first (420) and second (428) glass panels. One or more intermediate glass panels (436) can also be included. Spacer assemblies (438) are used to separate adjacent glass panels (420, 428, 436) and preferably include a desiccant-embedded sealant. Preferably, little or no metal structures are used in the spacers.
