Title: Improvements in and relating to light-controlling fittings
Inventor: ENGLISH SOLOMON
IPC: F21V5/00
Filed: 1958-04-21
Abstract: 863,737. Lighting fittings. HOLOPHANE Ltd. April 15, 1959 [April 21, 1958], No. 12561/58. Class 75(2). A light-controlling fitting formed so as to surround a light source provides azimuthal control of emergent beams by means of axially disposed prisms which concentrate the light into four main beams of which two are substantially 180 degrees apart in azimuth and the other two form 100 to 140 degrees apart, the latter pair of beams being preferably symmetrically disposed with respect to the former. The prisms are arranged in groups which deflect rays from the source into the main beams and there may be additional groups of prisms providing a general scatter of light not directed into the main beams. Clear or fluted regions may be interfused between adjacent groups of prisms. Fig. 2 is a plan view of a typical embodiment showing clear spaces 13, 17 located in the position of emergence of the respective pairs NB1, NB2 and FBI, FB2 of main beams from a light source at the centre of the fitting. The groups 12 and 18 of prisms deflect light into the respective beam pairs NB and FB, while the groups 11 divide the incident light equally between the two pairs of beams (see emergent rays 14 and 16). The fitting may additionally have circumferential prisms 23 (Fig. 1) which downwardly deflect the rays in each axial plane. The prisms 23 increase in power towards the top of the fitting, the upper members being reflecting and not refracting prisms. The reflecting prisms 26 reflect the light so as to direct it outwardly and the reflecting prisms 27 reflect it into the fitting to emerge through its base, in accordance with the disposition of the main beams. The angle of some at least of the prisms 23 may vary along the periphery so as to produce greater downward deflection of the rays in the NB beams than in the FB beams. In a bowl-shaped fitting, Figs. 4 and 5 (not shown), the closed lower part of the fitting includes axial prisms which are arcuate extensions of the axial prisms of the illustrated embodiment and also circumferential prisms which deflect the light upwardly. The fittings are designed for use in street lanterns so as to illuminate one side of a road with the NB beams and the other with the FB beams.
