Furthermore, the corresponding replacement module can be composed of individual parts, s. the above embodiments and in particular printed circuit board, heat sink and lens holder and held by the lens holder lenses as individual parts.
- a heat conducting device such as heat conducting foil, heat paste or the like may be arranged between them.
- a distance between the lens and the associated light source can be fixed. This can apply to both search light and work light or even only one of these lights. In other words, with such a fixed distance, focusing is not necessary, but the lens is in each case arranged such that, for example, the corresponding light source is already arranged in the focal point of the lens.
- the flashlight can then be recharged via a corresponding charger.
- the battery capacity indicator light can be used as the battery capacity indicator light.
- the hand lamp is used directly, there is an indication of a battery capacity in a critical area in which, for example, search light or work light operate in the flashing mode. Then the user of the flashlight can perform a corresponding charge.
- the flashing mode may include a continuous flashing or even a brief flashing.
- a brief flashing there is accordingly only a brief interruption of the search light or work light which otherwise operates in continuous operation.
- the printed circuit board has already been stated that this is designed for electrical supply and control of the corresponding light sources.
- Such a controller may include a monitoring of the flashlight, so that, for example, in particular after switching on the flashlight, a self-test is feasible.
- an automatic reduction of the light intensity takes place, which, for example, is possible if a user of the flashlight has become accustomed to a diminished ambient brightness after a certain time by adapting his eyes.
- the lamp housing can be formed from an upper lamp head housing part to a lower battery housing part, which are in particular pivotally connected to each other.
- the lamp head part could be pivoted relative to the battery housing part without the battery housing part taking part in the pivoting movement.
- This can be realized by a pivot axis between the two housing parts or by a gimbal connection between them.
- FIG. 1 is a perspective view of a portable handheld light according to the invention from one side and
- FIG. 2 shows a longitudinal section through the flashlight according to FIG. 1.
