Abstract

A fitting for horticultural illumination includes a reflector and a housing for auxiliary equipment, the reflector being attached to the housing by a universal coupling so that the reflector can be exchanged for a reflector with other properties, thereby reducing investments when crops are changed. According to a preferred embodiment the reflector includes a collar adapting it for coupling with the housing. Both the collar including the reflector and the housing are suspended by a profile, thus forming a pre-assembled unit which is suspended by hooks from a rail provided in the greenhouse to be illuminated.

Claims

1. A horticultural lighting fixture comprising, in combination, a housing unit for electrical connecting means and a lamp mounted in the housing unit and having a free end portion projecting from one end of the housing unit, a first reflector unit separate from the housing unit and spaced therefrom to overlie said free end portion of said lamp, and connecting means for detachably joining the housing unit and the first reflector unit in horizontally suspended, end-to-end relation.

2. A horticultural lighting fixture as defined in claim 1 wherein said connecting means comprises a profile detachably connected to said housing unit and overlying the housing unit and hook means detachably connecting the profile to the reflector unit.

3. A horticultural lighting fixture as defined in claim 2 including second hook means for suspending the profile from an overhead rail.

4. A horticultural lighting fixture as defined in claim 1 wherein said connecting means comprises a profile detachably connected to said housing unit and means detachably connecting the reflector unit to said one end of the housing unit.

5. A horticultural lighting fixture as defined in claim 1, including a second reflector unit which is cooperable with said connecting means to be detachably joined to the housing unit alternatively to said first reflector unit, said first and second reflector units having different configurations.

6. A fixture for horticultural lighting which comprises a profile, a housing for connecting equipment which includes monolithic hooks for supporting said housing below said profile, a lamp holder in said housing, a reflector having a first configuration and located adjacent said housing such that a lamp fitted in said lamp holder extends in the area of the reflector, first hook means for supporting the reflector below said profile, and second hook means which are movable in a longitudinal direction of the profile for supporting the profile below a supporting rail, said first hook means enabling said reflector to be replaced with a reflector having a second configuration which is different from said first configuration.

7. A fixture for horticultural lighting which comprises a housing for connecting equipment, said housing having an upper wall;

a lamp holder in said housing;

a mounting plate which extends substantially in parallel with a portion of said upper wall and which supports said connecting equipment and said lamp holder;

a reflector having a first configuration and located adjacent said housing such that a lamp fitted in said lamp holder extends into the area of the reflector, and connecting means for detachably joining the housing and the reflector and enabling said reflector to be replaced by a reflector having a second configuration which is different from said first configuration.

8. A fixture for horticultural lighting which comprises a housing for connecting equipment, said housing including an upper plate having a swivel through which cables can pass and power supply connections, a lamp holder in the housing, a reflector having a first configuration and located adjacent said housing such that a lamp fitted in said lamp holder extends into the area of the reflector, and connecting means for detachably joining the housing and the reflector and enabling said reflector to be replaced by a reflector having a second configuration which is different from said first configurations.

9. A fixture for horticultural lighting which comprises a housing for connecting equipment, said housing including an upper plate and a lower plate, said upper and lower plates being connected on one side by pivotable gripping means in the form of notches in the upper plate and cooperating cams on the lower plate and on an opposite side by locking means, said upper and lower plates providing a ventilation slit therebetween and said upper plate including ventilation apertures that are each surrounded by upwardly-extending rims to prevent entry of water;

a profile which extends above at least the ventilation apertures in the upper plate of the housing;

a lamp holder in said housing;

a reflector having a first configuration located adjacent the housing such that a lamp fitted in said lamp holder projects outwardly of the housing and into the area of the reflector; and

connecting means for detachably joining the housing and the reflector and enabling the reflector to be replaced by a reflector having a second configuration which is different from the first configuration.

10. A fixture according to claim 9, wherein the ventilation slit is protected against the entering of dripping water.

11. A fixture for horticultural lighting which comprises a housing for connecting equipment, a lamp holder in said housing for mounting a lamp such that it projects outwardly of said housing, a reflector having a first configuration and located adjacent said housing such that a lamp mounted in said lamp holder will extend into the area of the reflector, and a coupling element which supports said reflector and which is snap connectable to said housing in several positions to accommodate lamps of differing lengths, said coupling element enabling said reflector to be replaced with a reflector having a second configuration which is different from said first configuration.
