Lighting device and lighting tool

Abstract

The invention relates to a lighting device and a lighting tool. A semiconductor light-emitting element favorable for the cost aspect is used as the light source. The lighting device (10) comprises a thermal-conductive main body (13) with a substrate support part (13e) at one end; a substrate (14) provided with the semiconductor light-emitting element (11) and arranged on the substrate support part of the main body; a conductive wire-winding pin (15) arranged on the substrate and connected with the semiconductor light-emitting element (11); a lighting device (12) housed in the main body and lighting the semiconductor light-emitting element; a conductor for power supply (16) with one end connected with the lighting device and another end winded and connected with the wire-winding pin; a light seat part (17) arranged at another end side of the main body and connected with the lighting device. The lighting tool comprises a tool main body with a socket and the lighting device mounted on the socket of the main body. The cost is effectively reduced.

Description

technical field [0001] The present invention relates to a lighting device and a lighting fixture in the field of lighting technology, in particular to a lighting device and a lighting fixture using semiconductor light-emitting elements such as light-emitting diodes as light sources. Background technique [0002] In recent years, instead of incandescent lamps (filament lamps), lighting devices such as bulb-shaped LED lamps, which use light-emitting semiconductor light-emitting elements with long life and low power consumption, have been used as light sources for various lighting appliances. A lamp with a diode as the light source. When constituting a lighting device using such a light-emitting diode as a light source, it is of course possible to make use of the advantages of the light-emitting diode to form a small lighting device, and it is necessary to construct an inexpensive lighting device as a substitute light source for a general incandescent lamp. For example, Patent...

Problems solved by technology

[0003] However, in the LED lighting fixture disclosed in Patent Document 1, connector parts for connecting power supply wires for supplying power to the light-emitting diodes need to be provided on the LED module substrate, and there is a problem of cost increase.

[0004] It can be seen that the above-mentioned existing lighting devices and lighting fixtures obviously still have inconvenience and defects in structure and use, and need to be further improved urgently.

In order to solve the above-mentioned problems, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and general lighting devices and lighting fixtures have no suitable structure to solve the above-mentioned problems. , this is obviously a problem that the relevant industry is eager to solve
