Abstract:
In a lamp device 12 using a GX53-type cap 31 and also using an LED 56 as a light source, there is regulated an appropriate configuration of a metallic cover 32. A cap 31 and a lighting device 36 are arranged on an upper surface side of the metallic cover 32, and a substrate 33 on which the LED 56 is mounted is arranged on a lower surface side thereof. The metallic cover 32 has an approximately cylindrical shape with a maximum outer diameter D of 80 to 150 mm, a height H of 5 to 25 mm, and 2π (D/2) H/W, that is, an area of the outer peripheral surface per gross input power W to the lamp device 12 being in a range of 200 to 800 mm2/W. The gross input power W is 5 to 20 W.
Abstract:
A lighting fixture capable of efficiently radiating heat of a lamp device may be configured to be attached to a socket device. In some examples, by attaching the lamp device to the socket device, a cap portion of the lamp device is brought into contact with a fixture body, and pressed against and brought into close contact with the fixture body by an elastic body. Heat generated by lighting of LEDs of the lamp device is conducted from the cap portion to the fixture body and efficiently radiated.

An object of the present invention is to provide a light emitting element lamp and a lighting equipment effectively suppressing a temperature rising of a substrate on which a light emitting element is mounted by using a reflector. The present invention provides a light emitting element lamp 1 including: a heat-conductive reflector 2 having an emission opening portion and formed to be widened toward the emission opening portion with a reflecting surface 2a being provided on an inner surface side and an outer peripheral surface being exposed to an outside; a base 4 connected to the reflector 2 via a cover 3; a heat-conductive heat radiating member 8 provided on an inner peripheral surface of the reflector 2 and thermally connected to the reflector 2; a substrate 7 having a light emitting element 6 mounted thereon and attached to the heat radiating member 8 with a substrate surface being thermally connected to the heat radiating member 8 in a surface contact state; a lighting circuit 9 housed in the cover 3 to light the light emitting element 6; and a translucent cover 5 for covering the emission opening portion 2c of the reflector 2.
Abstract:
A light-emitting module may be configured to have improved light emission efficiency and light distribution characteristics. A light-emitting module may include a substrate having a front surface side as a component mounting surface and a rear surface side as a flat heat dissipating surface, a plurality of light-emitting elements arranged in a manner protruding at a central portion of the component mounting surface of the substrate. The light-emitting elements may radiate light at least in an upper surface direction and in a direction along the component mounting surface. The module may further include one or more lighting circuit components electrically connected to the light emitting elements by a wiring pattern arranged on the substrate and which is arranged closer to the peripheral edge side of the substrate than the light emitting elements on the component mounting surface of the substrate, and a connector for power supply connection.
Abstract:
A self-ballasted lamp includes: a base body; a light-emitting module and a globe which are provided at one end side of the base body; a cap provided at the other end side of the base body; and a lighting circuit housed between the base body and the cap. The light-emitting module has light-emitting portions each using a semiconductor light-emitting element, and a support portion projected at one end side of the base body, and the light-emitting portions are disposed at least on a circumferential surface of the support portion. A light-transmissive member is interposed between the light-emitting module and an inner face of the globe.
Abstract:
The form panel for placing concrete of the present invention is a form panel (30) comprising a hollow sheathing section (32) made of plastic, one side of which forms a concrete placing surface (31), and hollow side panel sections (33) bent out at right angles from both side edges of the sheathing section (32) on an opposite side of the sheathing section (32) to the concrete placing surface (31), wherein projecting sections (40) which extend in a vertical direction are provided on an outside surface (38) of the side panel section (33), and one of the sides of one of the projecting sections (40) is coplanar with the concrete placing surface (31) of the sheathing section (32), and on the projecting sections (40), notches (41) are formed at respectively the same position and orthogonal to the longitudinal direction of the projecting sections (40). This type of form panel (30)allows the formwork fittings used with conventional plywood form panels to be used at the time of erection (installation), is lightweight and has good workability, is durable, does not easily leak concrete, and can be recycled.
