Abstract

The invention relates to a lamp and the lighting equipment. The lamp includes: an element substrate, a heat radiator, a lamp socket, a receiving box, a lighting device and a heat conducting member. The element substrate has a light emitting element. The element substrate is installed on one end of the heat radiator and the other end of the heat radiator has a receiving recess. The lamp socket is installed on the other end side of the heat radiator. The receiving box is disposed in the receiving recess of the heat radiator; a part of the receiving box includes an opening part which is communciated with the receiving recess. The lighting device is received in the receiving box and performs the lighting control to the light emitting element. The heat conducting member passes through the opening part of the receiving box and the lighting device is in thermal connection with the surface of the receiving recess of the heat radiator.

Description

[0001] This application is a divisional application of the original application number 200910160870.4, the application date is July 28, 2009, and the invention name is "lamp device and lighting appliance". technical field [0002] The present invention relates to a lamp device and a lighting fixture including an element substrate on which a plurality of light emitting elements are arranged. Background technique [0003] Previously, with regard to a lamp device using a light emitting diode (Light Emitting Diode, LED) as a light emitting element, that is, an LED lamp (lamp), for example, as disclosed in Japanese Patent Application Laid-Open No. 2006-313718, uniformly installed An LED substrate, which is an element substrate of the LED, is mounted on one end side of the heat sink, and a globe is mounted on one end side of the heat sink to cover the LED substrate. Further, a housing case containing a lighting device for controlling lighting of the LED substrate is inserted into ...
