DE20023619U1 - Directional spotlight unit has housing provided with 2 relatively offset pivot axes for light source socket and associated conical reflector - Google Patents

Abstract

The spotlight unit has a housing (1) containing a socket (7) for an electric light source which is rotatable about an axis (II) perpendicular to the beam direction (I), enclosed by a conical reflector (8) rotated with the socket. The reflector projects beyond the edge (4) of the light exit opening (5) in the housing, with its pivot angle limited by the opening edge. The housing has 2 relatively offset positions for the pivot axis of the socket and the reflector.

Description

The The present invention relates to a light emitter having an in Radiation an opening with an edge housing, one in the housing arranged pivotably about an axis perpendicular to the emission direction Recording for a bulb and a surrounding the bulb, together with the receptacle pivoting reflector cone.

spotlights are known in different ways. It is important that the radiation direction the spotlight can be adjusted to illuminate certain objects. Freely projecting into the room spotlights usually have this one rotatable on one foot and pivotally mounted housing on, in which the bulb and the reflector housed are. For flush-mounted spotlights, it is known the reflector cone pivotally arranged in a housing and the case to train for flushing. The reflector is completely accommodated in the housing, and both close nearly flush with the installation surface from.

Of the Invention is based on the object, a light emitter of the beginning specify the type mentioned, on the one hand easy to manufacture and assembly is on the other hand good settings for the Reflector offers.

These Task is solved by that the reflector cone over the Edge of the opening protrudes in the housing and has a size such that its pivoting angle is limited by acting as a stop edge, wherein in the housing in particular at least two in the radiation direction staggered positions for the Pivot axis of the receptacle and the reflector cone are provided.

By the supernatant of the reflector about that casing is achieved that the casing the light cone of the light emitter is not affected. At the same time limited the edge of the case the tilt angle of the reflector cone in the desired manner. By at least two offset in the emission direction positions for the pivot axis the receptacle and the reflector cone in the housing, the maximum tilt angle in be adjusted easily. In a deeper arrangement the pivot axis in the housing is the maximum swing angle smaller, with a higher arrangement, So a larger supernatant of the reflector cone over the housing, the maximum swing angle is correspondingly larger.

The Limitation of the swivel angle over the housing edge is structurally inexpensive. Due to the different positions the pivot axis is given a simple adjustment. Prefers are for it Recesses in the housing for the pivot axis at different heights provided with respect to the emission direction.

The Swivel axis can be factory-fixed in the housing in a desired Height to be mounted. The provision of different positions in the housing makes the production cheaper and the storage costs.

The Pivot axle can also optionally on site in different Heights can be mounted. One and the same light emitter can thereby for different purposes be used.

Of the maximum tilt angle of the light emitter is preferably between about ± 15 ° and about ± 50 °, in particular adjustable between approx. ± 20 ° and approx. ± 40 °. The supernatant of the reflector the housing is between about 40 mm and about 60 mm. With these values is a good one Adjustability of the light emitter given.

To Another embodiment of the invention are the receptacle for the lamp and the reflector cone about a second perpendicular to the emission direction Axis which is perpendicular to the first axis, pivotally in the case arranged. The reflector cone is thus gimbaled suspended and can be inside of the housing predetermined swivel angle range in any direction be aligned, that is, it can be adjusted to any position over the 360 ° swivel circle become. The setting of the emission direction is special easy, and there are no dead areas.

Prefers is to realize the gimbal between recording and casing arranged an intermediate ring in which mounted a pivot axis is and in turn mounted with the other pivot axis in the housing is. This in turn is constructively inexpensive and allows one stable and reliable design.

The casing is preferred as a cross-section in particular circular pot educated. The recording for the light source, the electrical connection means and the gimbal Storage is thus protected on all sides. In addition, the pot may be preferred be designed for Unterputzeinbau.

One embodiment The invention is illustrated in the drawing and will be described below described. They show, in a schematic representation in each case:

1 a cross section through an invent to the invention light emitter and

2 a front view of the light emitter without reflector cone.

The illustrated light emitter comprises a pot-shaped housing 1 with a floor 2 , a wall 3 and a border 4 , the one opening 5 surrounds. On a carrier 6 is a recording 7 for a light bulb not shown here and a reflector cone 8th arranged. The reflector cone 8th surmounts the edge 4 of the housing 1 and is formed symmetrically to the emission direction I. The recording 7 also has not shown here electrical connection means for the light source.

The carrier 6 is by means of axle journal 9 in an intermediate ring 10 about a perpendicular to the emission direction I pivot axis II pivotally mounted. The intermediate ring 10 in turn is over axle journal 11 in the case 1 about a second to the emission direction I and the first axis II perpendicular right axis III pivotally mounted. The carrier 6 is thereby in the housing 1 gimballed.

For receiving the axle journal 11 the second axis III has the housing 1 two pairs of offset in the emission direction I recesses 12 on, in which the journals 11 can be used optionally. In this way, the intermediate ring 10 and with this the carrier 6 with recording 7 and reflector cone 8th in two different heights in the housing 1 to be ordered. Depending on the arrangement of the intermediate ring 10 the supernatant a of the reflector cone changes 8th over the edge 4 of the housing 1 and thus the maximum pivoting angle α of the reflector cone 8th which determines the possible emission directions I. At the in 1 shown higher arrangement of the intermediate ring 10 If the maximum swivel angle α is greater, it is smaller in the lower arrangement.

The supernatant a of the reflector 8th over the edge 4 of the housing 1 is preferably between about 40 and about 60 mm, the maximum pivoting range in the upper position preferably about ± 35 °, in the lower position preferably about ± 20 °. The housing can, as shown, are circular. But there are also other cross-sectional shapes possible. The housing is also preferably designed for Unterputzeinbau and provided with suitable holding means.

Of the illustrated and described light emitter is simple and inexpensive in the production and allows a good adjustability of the emission direction. He is to the Unterputzeinbau suitable and possible an adjustment of the possible Angular range of the emission direction.
