Definitions
- the invention relates to a headlight according to the preamble of claim 1.
- Such generic headlights known from the prior art deliver good luminous efficacy, but cannot be focused.
- the mobility of the lamp in the Reflector is often very limited in these headlights, and the one mentioned always serves Movability of the lamp only to find an optimal lamp position in which the most uniform possible light distribution is achieved.
- the lamp is outside this optimal position, the generic headlights deliver a very uneven Light distribution with several ring-shaped maxima and minima of the light intensity distribution. This is the same effect that occurs regularly with flashlights, provided that these are built with a smooth, deep reflector.
- Focusable headlights are also known from the prior art, however, these always work with flat reflectors, from which - especially with a small beam angle (Spot position) - a very poor light yield results.
- the object of the invention is based on the generic headlight to provide a headlamp that delivers high luminous efficacy and at the same time is focusable.
- this object is achieved by a headlight according to claim 1.
- the arrangement of the diverging lens is very important in the headlight according to the invention between the reflector and the converging lens. Only this diverging lens enables in interaction with the lamp that is movable within the reflector cavity desired focusability, while the deep reflector guarantees a high light output.
- the light distribution is not when the headlight according to the invention is focused perfectly even, but according to the state of the art there was a focus on headlights not possible with comparable light output.
- Headlamp according to claim 5 ensures extremely good beam guidance with regard to a uniform illumination of the area to be illuminated for everyone Angle.
- the special design of the diverging lens in the preferred embodiment according to Claim 14 ensures that the surface to be illuminated is special at every beam angle is evenly illuminated.
- the diverging lens with its central part has a different function exercise than with their edge area. So z. B. ensure that at all Positions of the optical system the entire diameter of the front lens (converging lens) is illuminated. This is particularly advantageous when creating soft shadow edges should be, the headlight according to the invention as a kind of focusable soft light should serve.
- the embodiment of the headlight according to the invention shown in FIG. 1 has a curved reflector 1 and one within the cavity formed by the reflector 1 arranged lamp 2 on.
- a reflector, where the lamp is inside the by the Reflector formed cavity is also referred to as a "deep reflector".
- the lamp 2 is a filament lamp in the illustrated embodiment, but can instead of the filament lamp 2, a gas discharge lamp or a lamp from another Type can be used.
- the lamp 2 is capped on one side in a base and movement device 3.
- the Reflector wall has an opening 4 for the base and in its rear center Movement device 3 on.
- the lamp 2 is switched on via the base and movement device 3 connected to an electrical voltage source.
- the base and movement device also serves 3, the lamp 2 within the cavity formed by the reflector 1 relative to the reflector 1 in the direction of the main optical axis of the headlight according to the invention to move back and forth.
- a converging lens 5 is arranged in the radiation direction of the reflector-lamp combination 1, 2.
- a biconcave diverging lens 6 In the direction of radiation between the reflector-lamp combination 1, 2 and the converging lens 5 there is a biconcave diverging lens 6. The one facing the lamp 2 The surface of the diverging lens 6 was subjected to a special surface treatment and consequently has a microlens structure.
- the converging lens 5 is a Fresnel lens made of plastic.
- the headlamp according to the invention Collecting lens 5 mounted in a fixed position on the headlight housing 7.
- the reflector 1 and the diverging lens 6 are mounted in a fixed position on a carriage 8, which as such in Direction of the optical axis of the headlamp can be moved back and forth.
- the floodlight position of the headlamp results when the carriage 8 in its closest possible position in the Near the converging lens 5.
- the spot position is obtained from the headlight construction predetermined maximum possible distance of the carriage 8 from the converging lens 5.
- the embodiment shown in Fig. 2 of the headlamp according to the invention corresponds essentially to the embodiment of FIG. 1. The difference is that that in the embodiment of Fig. 2, the rear center of the reflector 1 'closed and the lamp 2 'is base on two sides.
- the reflector wall has two guide slots to accommodate and guide the movement of the two-sided lamp base.
- the lamp 2 ' is within the range defined by the reflector 1'. formed cavity in the direction of the main optical axis of the headlamp relative to Movable reflector 1 '.
- the reflector 1 is a rotating body, the shape of which is obtained by rotating a curve section P about the main optical axis of the headlight.
- the main optical axis of the headlight is represented in the coordinate system of FIG. 3 by the x-axis.
- the curve section P is a curve section of a smooth curve C that can be described by a polynomial function. This curve C is shown in FIG. 4.
- P is equal to C in the limits [y 1 , y 2 ]. As can be seen in FIG. 4, the extreme point of C is not on the main optical axis of the headlight.
- an embodiment of the headlamp according to the invention which is designed so that the diverging lens makes a relative movement to the reflector, in coordination with a simultaneous relative movement between light source (lamp) and reflector and one simultaneous third movement of lamp, reflector and diverging lens in relation to the Converging lens.
- the headlight is the lamp 2 in a base and movement device 3 on one side socketed.
- the reflector wall has an opening 4 for in its rear center Base and movement device 3.
- the embodiment shown in FIGS. 5a to 5c of the headlamp according to the invention thus essentially corresponds in this respect the embodiment of Fig. 1, even if the specific versions of the lamp 2 and the base and movement devices 3 themselves, as already shown in the purely schematic Drawings differ, differ in their construction.
- the mathematical construction of the reflector 2 in the embodiment of FIGS. 5a to 5c Construction of the reflector 2 from the embodiment of FIG. 1, as already mentioned above 3 and 4 has been explained.
- Headlights are both the converging lens 5 (front lens) and the diverging lens 6 Fresnel lenses formed.
- the reflector 1 is in the direction of the main optical axis of the Movable headlights.
- the lamp 2 is in the direction of the main optical axis of the Movable headlights.
- the diverging lens 6 is in the direction of the optical one The main axis of the headlamp can be moved. When shifting from flood position to spot position of the headlight, the diverging lens 6 moves away from the converging lens 5, the reflector 1 shifts away from the diverging lens 6 and the lamp 2 shifts into the reflector 1.
- the headlamp is designed so that the aforementioned displacements of the reflector 1, the lamp 2 and the diverging lens 6 by means of a uniform movement mechanism in a predetermined, coordinated manner be carried out that, viewed over a complete shift between the flood position and the spot position of the headlamp, when this complete shift is divided into several shift sections, there is no linear relationship between the respective shift lengths of the reflector 1, the lamp 2 and the diverging lens 6.
- the last-described embodiment of the headlamp according to the invention is designed such that when the flood position is shifted to the spot position, the distance between the diverging lens 6 and the converging lens 5 grows more rapidly than the distance between the diffuser lens and the converging lens 5 Reflector 1 and the diverging lens 6, while in the partial section of the shift immediately before the spot position, the distance between the diverging lens 6 and the converging lens 5 and the distance between the reflector 1 and the diverging lens 6 increase in approximately the same way.
- the displacements of the reflector 1, the lamp 2 and the diverging lens 6 in the illustrated can perform predetermined, coordinated manner are known to those skilled in the art State of the art, and the production of such a uniform movement mechanism belongs in the area of his common manual skills. Therefore there is no need a detailed description of the corresponding movement mechanics at this point.
