Definitions

• the invention relates to a lighting device which is worn on or immediately in front of the forehead or above or next to the eyes, for e.g. Medical applications for illuminating a treatment area with integrated energy supply, characterized in that several non-thermal, light-emitting elements are provided as the light source, and in that the individual high-emitting elements emit the light with a defined radiation direction and are arranged in such a way that the generated light is bundled ,
• the invention relates to a lamp which is worn on or immediately in front of the forehead or above or next to the eyes, and by which the user of the lamp is neither restricted nor hindered in his freedom of movement by cables or other connections.
• a lamp is e.g. for medical applications, to illuminate the treatment area during diagnosis or treatment.
• this lamp can also be used for non-medical applications in which there is a similar lighting problem.
• Head-mounted lights and lighting devices were designed in different versions, especially for the medical field.
• the light is either a) generated directly in front of or on the head of the user, or b) generated in an external light source and directed to the end of the user via light guides made of glass, plastic or liquid.
• the freedom of movement of the user is more or less hindered or restricted by the light guide cable, and the weight of the light guide creates an uncomfortable tension that leads to muscle tension in the neck, to headaches or other premature signs of fatigue.
• there are also wireless energy sources in use which allow the head of the user of the lamp to move freely, but the light sources used are thermal in nature, with the result that considerable heat is generated in front of or above the forehead of the user.
• the light generation process is carried out with low efficiency, so that the accumulator packs or batteries used conventionally are relatively heavy, which in turn leads to the fatigue phenomena mentioned above.
• the light from the thermal light sources only by means of suitable optics must be bundled, which leads to relatively high weight and bulky dimensions of these headlights.
• the invention has for its object to avoid the above-described shortcomings of conventional headlights and is characterized in that several non-thermal, light-emitting elements are provided as the light source, and that the individual light-emitting elements emit the light with a defined direction of radiation and arranged so are that the generated light is bundled. It is thus advantageous that
• the light generation directly on the head i.e. in front of the forehead above the eyes or to the side of the user's eyes using non-thermal, highly emissive elements.
• These light sources are preferably designed as light-emitting semiconductors, the radiation of which is modified in such a way that the impression of white light is produced for the human eye. On the one hand, this ensures a high degree of efficiency in converting electrical energy into light, and on the other hand, the light radiation is highly directional due to the mode of action and the structure of these high-emitting semiconductors.
• This bundling of the emitted light is used in the present invention, namely in that
• the highly emitting elements are attached in such a way that the user can adjust the position of the lighting field generated according to points 2 to 4 at high altitude to suit his observation or work requirements.
