An air filter for an image forming apparatus includes a housing including an air intake part and an air exhaust part, a fan disposed in the housing to form an air flow from the air intake part to the air exhaust part, and a filter disposed in the housing to filter the air flow. The fan draws air in a suction direction along an ejection direction of a sheet ejected from an ejection port in the image forming apparatus.

Air filter and image forming apparatus incorporating same

An image forming apparatus includes an electric wire and an electric box. The electric box extends substantially horizontally and includes a wire connector coupled to the electric wire. A body face exposes the wire connector. An outer cover covers the body face. The outer cover includes a slot and a wire accommodator. The slot is disposed opposite the wire connector to expose the wire connector to an outside of the image forming apparatus. The wire accommodator accommodates the electric wire.

A first terminal for forming an electrical connection to a power feeding terminal of a first lamp socket is provided in the first cap. A second terminal for forming an electrical connection to a grounding terminal of a second lamp socket is provided in the second cap.

Straight tube LED lamp, lamp socket set, and lighting fixture

An image forming apparatus includes an apparatus body, a sheet stack face disposed in an upper portion of the apparatus body, a pair of sheet ejection rollers to eject a sheet onto the sheet stack face in an ejection direction toward a front side of the apparatus body, a hinge secured to the apparatus body, and a control panel disposed higher than the apparatus body and supported by the hinge rotatably around the hinge. The control panel is rotatable within a movable range positioned higher than a trajectory drawn by the sheet ejected onto the sheet stack face.

Image forming apparatus

An impact reduction device includes a pressing mechanism in an open-close device to press a first member in a direction in which the first member returns to an initial state. The open-close device includes the first member independently rotatable around a shaft from the initial state to a first angle, and a second member integrally rotatable with the first member around the shaft from the initial state to a second angle greater than the first angle. The pressing mechanism presses the first member in the direction in which the first member returns to the initial state using a first force until the first angle is reached, and presses the first member in the direction in which the first member together with the second member returns to the initial state using a second force greater than the first force between the first angle and the second angle.

Impact reduction device and image forming apparatus

A light-emitting device includes a substrate having a front surface on which a semiconductor light-emitting element is mounted. A front cover is provided which thermally contacts the front surface of the substrate at a periphery of the semiconductor light-emitting element and is disposed on a front side of the substrate. A heat conduction path is formed along which heat generated by the semiconductor light-emitting element is conducted in order of the substrate and the front cover and the heat is radiated from a front surface of the front cover, so that a heat radiation property from a front surface of the light-emitting device is improved.

Light-emitting device and lighting apparatus

In a lamp deviceusing a GX53-type capand also using an LEDas a light source, there is regulated an appropriate configuration of a metallic cover. A capand a lighting deviceare arranged on an upper surface side of the metallic cover, and a substrateon which the LEDis mounted is arranged on a lower surface side thereof. The metallic coverhas an approximately cylindrical shape with a maximum outer diameter D of 80 to 150 mm, a height H of 5 to 25 mm, and 2&#x3c0; (D/2) H/W, that is, an area of the outer peripheral surface per gross input power W to the lamp devicebeing in a range of 200 to 800 mm/W. The gross input power W is 5 to 20 W.

Lamp device and lighting fixture including LED as light source and metallic cover

The present invention comprises a lighting apparatus main body having a reflecting surface, a main light source arranged in the reflecting surface of the lighting apparatus main body, a sub-light source which is arranged at the lighting apparatus main body and illuminates the neighborhood of the main light source directly, and a control circuit which controls the main light source and the sub-light source. Since the lighting apparatus illuminates downward with a direct illumination of the main light source and an indirect illumination of the sub-light source, the glare of the main light source is reduced.

Lighting apparatus

According to one embodiment, a lamp apparatus includes a light-emitting module, housing, and a lighting circuit. The light-emitting module includes a light-emitting element. The housing opens in the direction of irradiation of a light beam and having a cap on a side opposite from the direction of irradiation of the light beam. The cap is provided with a light-emitting module mounting portion projecting in the direction of irradiation of the light beam and the light-emitting module is mounted on the light-emitting module mounting portion. The lighting circuit is accommodated in the housing.

Luminaire and lamp apparatus housing

Both ends of a lamp body are mounted on sockets of an apparatus body and a feeding unit configured to feed power to LEDs is provided on the back side facing the apparatus body of the lamp body.

Tube lamp and luminaire

A luminaire capable of contacting a lamp device to a luminaire main body is provided. A luminaire includes a luminaire main body that includes an abutment portion in which heat is transferred and a mounting receiving portion, a socket device that includes a socket main body having an opening portion, an engagement receiving portion which is provided in the opening portion, a mounting member which is fixed to the mounting receiving portion, a receiving portion which receives an elastic member generating an elastic force between the socket main body and the mounting member, and a connection portion which is electrically connected to an external power source, and is mounted so as to move in the elasticity direction of the elastic member with respect to the luminaire main body by the mounting member, and a lamp device that includes a contact portion which contacts the abutment portion, an engagement portion which engages with the engagement receiving portion, and a lamp side connection portion which is electrically connected to the connection portion, wherein the abutment portion of the luminaire main body and the contact portion of the lamp device closely contact with each other by the elastic force of the elastic member according to an operation in which the engagement portion of the lamp device and the engagement receiving portion of the socket device are engaged with each other.

Luminaire

In a power supply device according to one embodiment, a reference signal (Vref), which changes from a value corresponding to a maximum current in a full lighting state to that corresponding to a minimum current in case of a deepest dimming depth, and a reference signal (Vref), which changes from a value corresponding to a load voltage at the time of a maximum current in a full lighting state to that corresponding to a minimum current in case of the deepest dimming depth, are prepared in accordance with dimming depths of a dimming signal. In a shallow dimming depth region close to a full lighting state, the reference signal (Vref) is selected to apply constant-current control to light-emitting diodes in a current control mode. In a deep dimming depth region, the reference signal (Vref) is selected to apply constant-voltage control to the diodes in a voltage control mode.

Power supply device and lighting equipment

To a constant-current power supply whose output current can be variably set, light emitting modules can be connected in parallel. A control unit recognizes connection information outputted from an information output unit provided in each of the light emitting modules and varies the output current of the constant-current power supply. Drive can be controlled in response to a state of the connected light emitting modules such as the connecting number of light emitting modules.
