Embodiment Construction

[0015] An embodiment will be described below with reference to the drawings.

[0016] exist figure 1 as well as figure 2 Among them, the reference numeral 11 is a light bulb-shaped lamp as a lighting device, and the light bulb-shaped lamp 11 has: a cylindrical base body 12; one end side) of the light source unit 13; the lens 14 mounted on the light source unit 13; the globe 15 covering the light source unit 13 and the lens 14 and mounted on one end side of the base body 12; the cover 16 arranged in the base body 12; A base 17 attached to the other end side of the cover 16 ; and a lighting circuit 18 arranged in the cover 16 . In addition, the length of the light bulb-shaped lamp 11 in the lamp axis direction and the outer diameter of the largest diameter portion of the globe 15 have dimensions equivalent to those of a small krypton bulb, and have a shape that approximates the shape of the small krypton lamp.

[0017] In addition, if Figure 1 to Figure 4 As shown, the bas...

Abstract

The invention provides a self-ballasted lamp and a lighting fixture. The lens can be easily arranged in the light source unit so that the lens body of the lens is arranged facing the light source of the light source unit, a positional relationship between the light source and the lens can be adjusted and light distribution performance can be stabilized. The self-ballasted lamp includes a base body, a light source unit attached to one side of the base body, a lens attached to the light source unit, a cap provided on the other side of the base body and a lighting circuit arranged in the space provided by the base body and the cap. The light source unit includes a light source constituted by semiconductor light emitting elements. The lens has a lens body facing the light source and an attachment leg for attaching the lens body to the light source unit. A claw portion to be secured to the light source unit can be provided on the attachment leg.

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 same. Background technique [0002] There are light bulb-shaped lamps using LED elements as light sources instead of incandescent lamps. In this light bulb-shaped lamp, a substrate on which LED elements are mounted to form a light source is mounted on one end surface of a base body, and a globe covering the light source is mounted on one end of the base body. [0003] Generally, an incandescent lamp has a wide-angle light distribution characteristic in which both the luminance in the optical axis direction and the luminance in the direction intersecting the optical axis direction are high. Since the luminance in the axial direction is high and the luminance in the direction intersecting with the optical axis direction is low in light distribution characteristics, it may not be suitable ...
