Problems solved by technology

[0006] However, when a lens is used in a light bulb-shaped lamp, the lens cannot be easily arranged to face the light source, or the positional relationship between the lens and the light source cannot be adjusted.
As a result, light distribution characteristics tend to vary

Abstract

The present invention provides a light bulb-shaped lamp and a lighting device in which a lens can be easily arranged to face a light source, and a positional relationship between the light source and the lens can be adjusted to stabilize light distribution characteristics. The light bulb-shaped device includes a base, a light source unit attached to one side of the base, a lens attached to the light source unit, a base provided on the other side of the base, and a lighting circuit arranged in a space formed by the base and the base. The light source unit includes a planar light source composed of semiconductor light emitting elements. The lens has a lens main body facing the planar light source, and a mounting foot for mounting the lens main body on the light source unit, and a claw portion for fixing to the light source unit is provided on the mounting foot.

Description

technical field [0001] Embodiments of the present invention relate to a light bulb-shaped lamp using a semiconductor light-emitting element as a light source, and a lighting device using the light bulb-shaped lamp. Background technique [0002] Currently, there is a light bulb-shaped lamp using an LED element as a light source that can replace an incandescent lamp. In this bulb-shaped lamp, a substrate on which an LED element is mounted to form a light source is mounted on one end surface of a base, and a globe covering the light source is mounted on one end of the base. [0003] Generally, an incandescent lamp has a wide-angle light distribution characteristic with high brightness in the direction of the optical axis and in a direction intersecting the direction of the optical axis. Due to the light distribution characteristics of high brightness in the axial direction and low brightness in the direction intersecting the optical axis direction, it may not be suitable for u...
