Problems solved by technology

However, since the ratio of the area of ​​the light-emitting part to the substrate increases, the LED element and the screw will be brought closer to the substrate, and the insulating state between the LED element and the screw may not be maintained.
In addition, in the above-mentioned light bulb type lamp, although there is a specification for insulation and withstand voltage, since the insulation distance between the LED element and the screw cannot be ensured on the substrate, the specification for insulation and withstand voltage may not be satisfied.
Therefore, it is not easy to increase the brightness of the light bulb type lamp
[0004] In addition, it is not easy to reduce the size of the substrate if it is to maintain the insulating state of the LED element and the screw.

Abstract

The invention provides a bulb type lamp and a lighting device. The problem of insulation on a base board is resolved, areas of a lighting part on the base board can be enlarged, and miniaturization of the base board is achieved. A lighting module is arranged on one end side of a frame of the bulb type lamp, a lamp holder is arranged on the other end side of the frame, and a lighting circuit is contained inside the frame. The lighting module is provided with the lighting part comprising a semiconductor lighting element arranged on the base board, an embedding part of a fixing component having insulativity is embedded into one end side of the frame, and therefore the base board is fixed.

Description

technical field [0001] Embodiments of the present invention relate to a light bulb-type lamp using a semiconductor light-emitting element as a light source, and a lighting device using the light bulb-type lamp. Background technique [0002] Currently, in a light bulb type lamp using a semiconductor light emitting element (for example, an LED element) as a light source, a light emitting portion using an LED element is provided on a substrate, and the substrate is disposed on one end side of a casing and fixed to the substrate by a plurality of screws. on the casing. In addition, a cap is provided on the other end side of the casing, and the lighting circuit is accommodated in the casing. In addition, heat generated when the LED element is turned on is transferred from the substrate to the housing, and dissipated into the air through the housing, thereby suppressing an increase in the temperature of the LED element. [0003] When increasing the brightness of a light bulb-typ...
