  • Fire stop for light fixture
    Patent number: 7670033
    Abstract: A fire stop for use with a light fixture in a suspended ceiling or wall. It prevents flames and smoke from passing through the light fixture and spreading throughout a building by moving above the ceiling or behind the walls. The fire stop has a lightweight enclosure that defines an interior space disposed above the suspended ceiling, or behind the wall. Contained within the interior space are a portion of the light fixture and a layer of intumescent material. The intumescent material forms a material with a relatively low thermal conductivity that substantially fills the interior space, impeding the movement of flames or smoke, when the intumescent material reaches at least a pre-determined activation temperature.

  • Vehicle lamp
    Patent number: 7665868
    Abstract: The disclosed subject matter can include a vehicle lamp having a favorable light distribution and an effective heat dissipation structure. The vehicle lamp can include a light source and a casing in which the light source is sealed. The casing can be configured in a tubular shape and a reflector can be configured in a hollow of the casing. The casing can be sealed between the reflector and a front lens configured to allow light emitted from the light source to pass therethrough. The inner surfaces of the casing and the reflector can be configured to form a predetermined light distribution via the front lens. The outer surfaces of the casing and the reflector can be exposed to the outside and can be configured to radiate heat generated from the light source to the outside using heat conductive material. Thus, the lamp can be miniaturized and provide favorable light distribution.

  • Vehicle warning lamp
    Patent number: 7651242
    Abstract: A wheelchair lamp that is primarily for making a wheelchair more visible. The wheelchair lamp includes a housing that is mounted to the wheelchair. An extendable member having a light on top extends from the housing. The extendable member may be extended and retracted. A motor is contained within the housing to extend and retract the extendable member. An electrical conductor is longitudinally disposed with the extendable member. The electrical conductor electrically connects the light and the power source. A switch is used to selectively connect the motor to the power source causing the motor to operate so that the motor may extend or retract the extendable member.

  • Liquid crystal display device
    Patent number: 7651249
    Abstract: If a forced convection is generated by a cooling fan, there is generated a problem that a natural convection is prevented and a cooling effect in a region of the natural convection is lowered. The invention provides a structure in which an air flow generated by a forced convection does not come into contact with an air flow generated by a natural convection, by setting a partition all between a forced convection path in which the air flows on the basis of a forced convection generated by a cooling fan, and a natural convection path in which the air flows on the basis of a natural convection. Further, the partition wall is not provided near an upper end so as to draw in the air flowing through the natural convection path to a side of the forced convection path, thereby promoting the natural convection of the natural convection path.
