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.

Light-emitting module and lighting apparatus

A light emitting element lamp and a lighting equipment for suppressing a temperature rising of a substrate on which a light emitting element is mounted by using a reflector is described. Aspects relate to a lamp including a heat-conductive reflector, a base connected to the reflector, a heat-conductive heat radiating member, a substrate having a light emitting element mounted thereon and attached to the heat radiating member and a lighting circuit housed in the cover to light the light emitting element. Other components and features may also be included.

Light emitting element lamp and lighting equipment

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.

By attaching the lamp deviceto the socket device, a cap portionof the lamp device is brought into contact with a fixture body, and pressed against and brought into contact with the fixture bodyby an elastic body. Heat generated by lighting of LEDsof the lamp deviceis conducted from the cap portionto the fixture bodyand efficiently radiated.

Lighting fixture

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.

Lighting system

Socket device

An object of the present invention is to provide an LED bulb in which temperature of a lighting circuit is suppressed from rising during lighting of an LED so that life time of the lighting circuit is maintained without increasing manufacturing cost of components. According to the invention, an LED modulehaving multiple LEDs surface-mounted thereon is mounted in a heat dissipating unit. Heat generated by the LEDs is dissipated through multiple heat dissipating finsof the heat dissipating unit. A glove, covering the LED module, radiates outward radiant light from the LEDs. A lighting circuitfor lighting the LEDs is incorporated in an inner hollow portionof a caparranged on a side opposite to the gloveof the heat dissipating unit. Accordingly, the heat generated by the LEDs of the LED moduleis mostly dissipated by the heat dissipating unit, thereby suppressing the temperature of the lighting circuit from rising.
