LAMP HAVING OUTER SHELL TO RADIATE HEAT OF LIGHT SOURCE
First Claim
Patent Images
1. A lamp comprising:
- a heat conductive outer shell which includes a peripheral portion, a light source support provided on one end of the peripheral portion and a recess opening at the other end of the peripheral portion;
a base provided on the other end of the outer shell;
a light source mounted on the light source support to transfer heat to the light source support;
a cover mounted on the outer shell to cover the light source;
a lighting circuit housed in the recess;
an insulating member provided between the lighting circuit and an inner surface of the recess; and
a heat shielding cover which, with the peripheral portion of the outer shell, defines a heat radiating path, the heat radiating path continuing in the axial direction of the outer shell, and an ascending current generated in the heat radiating path flows from the lower side to the upper side of the heat radiating path when a heat of the light source is conducted to the outer shell.

Abstract
A lamp includes an outer shell having heat conductivity, a base provided in the outer shell, and a cover provided in the outer shell. The outer shell has a light source support, and a heat radiating surface exposed to the outside of the outer shell. The light source support is formed integral with the heat radiating surface. A light source is supported on the light source support. The light source is heated during lighting, and thermally connected to the light source support. The light source is covered with the cover.

8. A lamp comprising:
-
an outer shell with a light source support; a light source supported on the light source support to transfer heat to the light source support; a cover which covers the light source; and a heat shielding cover which, with the outer shell, defines a heat radiating path continuously in the axial direction of the outer shell, the heat radiating path having a first end which is connected to the outside of the outer shell by a first port and a second end which is connected to the outside of the outer shell by a second port, and an ascending current is generated in the heat radiating path when a heat of the light source is conducted to the outer shell.
