First Claim
1. A flashlight, comprisinga lamp support;
- the lamp support having a joining part;
the lamp support having a light-reflecting cup adjoining a first end of the joining part;
the joining part having a threaded portion on a second end thereof;
an electric light-generating mechanism held in the joining part of the lamp support;
the electric light-generating mechanism including a circuit board, and a light source;
the circuit board having a controlling circuit thereon;
a front heat-conducting component interposed between the lamp support and the electric light-generating mechanism;

Abstract
A flashlight includes a lamp support, an electric light-generating mechanism in the lamp support, a covering member around the lamp support, a barrel body joined on the covering member, and an adjustment member; the adjustment member is threadedly joined in the lamp support, and can be turned to adjust a position of a focal point of light emitted from a light source of the light-generating mechanism; front and rear heat-conducting components are positioned on front and rear ends of the light-generating mechanism respectively, and they contact the lamp support and the barrel body respectively; heat produced from functioning of the light-generating mechanism will be conducted away from the front heat-conducting component to the lamp support and from the rear heat-conducting component to the barrel body, and the light source is prevented from being damaged by the heat produced from it continuing shining for an extended length of time.
