Problems solved by technology

But the directional properties of the reflector are lost by such measures
In order to correct or change the reflection characteristics of such spotlights, an additional condenser lens is also used as the front lens, but this means increased material and processing costs, because the corresponding suitable front lens must be prepared, selected and used according to the actual position of the bulb. lens
[0004] In addition, although focusable spotlights are also known from the prior art, these are always operated with flat reflectors, as a result of which - especially at small reflection angles (positioning positions) - a very poor utilization of light results.

Embodiment Construction

[0019] figure 1 The illustrated embodiment of the spotlight according to the invention has a curved reflector 1 and a bulb 2 arranged in the cavity formed by the reflector 1 . A reflector in which the bulb is arranged in a cavity formed by the reflector is also called a "deep reflector". The bulb 2 is a filament bulb in the illustrated embodiment, but a gas discharge lamp or other types of bulbs could also be used in its place.

[0020] The light bulb 2 is plugged into a socket and mobile device 3 on one side. The reflector wall has an opening 4 for the socket-and-moving device 3 in its opposite center. Via the socket - and the mobile device 3 - the light bulb 2 is connected to the power supply. Furthermore, the socket and displacement device 3 serves to move the bulb 2 in the cavity formed by the reflector 1 back and forth relative to the reflector 1 in the direction of the optical axis of the spotlight according to the invention.

[0021] A condenser lens 5 is arranged i...

Abstract

A spotlight has a curved reflector (1, 1') and a lamp (2, 2') arranged inside a cavity formed by the reflector (1, 1'). The lamp (2, 2') and the reflector (1, 1') are movable relative to one another in a direction of a main optical axis of the spotlight. A converging lens (5) is arranged in front of the reflector (1, 1') in a direction of light emission. A dispersive lens (6) is arranged between the reflector (1, 1') and the converging lens (5).

Description

technical field [0001] The invention relates to a spotlight, especially a focusable spotlight equipped with a negative lens. Background technique [0002] Such spotlights according to the classification known from the prior art provide good light utilization, but cannot be focused. The movability of the bulb in the reflector is often very limited in these spotlights, and said movability of the bulb is always only used to find the best position for the bulb to achieve as uniform a distribution of light as possible. If the bulb is outside this sweet spot, such spotlights provide a very uneven light distribution with several rings of maximum and minimum light intensity distribution. Flashlights will have the same effect as long as they are designed with a smooth deep reflector. [0003] According to the prior art, attempts have been made to compensate said inhomogeneities of the light distribution on these spotlights by means of a textured, ground reflector. However, the dir...
