lineal / 340 series
Introduced in 1936 or 1937. Designed to produce suitable vertical and lateral light control in conjunction with Sodium Discharge Lamps. The light is controlled by two double refractor plates and an arrangement of top reflectors. The light flux is divided into a well-controlled two-way non-axial distribution, while the low brightness of the refractor lantern ensures excellent visibility. The prisms on the refractors run horizontally and are on the sides of the plates which face each other when sealed together. In this way it is possible to arrange for the exterior of the refractors to be smooth. As the light source is placed horizontally across the street, the distribution from the units is wide in plan. In the vertical plane there is no sharp cut-off, so that the spread up and down the street is also wide. Uses the Prismatic refractor panel 781 (although the catalogue number suggests its used the earlier 780 refractor). This gives a wide lateral light distribution without glare. The Prismatic panels are constructed in two pieces with the prisms formed internally so that all exposed surfaces are smooth. The lantern had several minor improvements before the 1939 APLE exhibition.

Cut-Off Lantern
Described as a cut-off lantern with a 150° non-axial distibution.
546/2/4562 500W GLS ES Top Entry No Gear 1939 Programme





Bi-Way Directional Refractor Lantern
Also manufacturered as the Siemens Bi-Way. The refractor is 160° non-axial. It has internal vertical prisms for the production of the main beams and a smooth exterior, except for the bottom and a small area on the footpath side where there are external prisms. Two designs of this refractor have been produced: one where the prisms are arranged to give a non-axial asymmetirc distribution (as shown in the isocandle diagram) and an axial asymmetric distribution. In the non-axial form it is made in two sizes: the larger for 250W and 400W lamps, and the smaller for 150W and 250W lamps. The lantern was used in the Westminster experiments of 1937 and was fitted with a variety of axial and non-axial bowls with different main beam angles. (Section diagram believed to be of this lantern - found in 1939 paper).

This lantern embodies one of the most advanced and efficient types of bowl refractors, designed for use with vertically-burning Mercury Discharge Lamps. The light control is obtained by the use of patented reflector diffuser prisms carried on the inside of the glass, which are so designed as to give a wide spread of light at relatively low angles and a more restricted spread at high angles of emission, thus varying the width of the beams to match the angular width of the roadway at different angles of elevation.

Two sizes are available, to suit Groups "A" and "B" installations, while the refractor bowl can be supplied in alternative types to provide symmetrical, two-way axial, or two-way non-axial distributions. The lantern is also available for side entry mounting.

Cylinder Light Lantern
Introduced in 1939. Uses a new type of Prismatic Refractor to be used with horizontal discharge lamps. To be used with horizontal light sources. The Refractor System exercises control over the whole 360° of light flux emitted by the lamp, the major portion of the flux being projected towards the road surface, and the remainder being directed to an upper reflector designed for re-direction at a high angle to the distant road surface. As a high peak of efficiency and light control in the region of 85°.

Dublin Lantern
First installed in Dublin in 1939. Fitted internally with refractor glasses to control the distribution of light. All exterior metal parts of the lanterns are executed in bronze. A small number of internal metal parts are executed in steel and aluminium alloy, the remainder being made of bronze. An anti-condensaiton chamber is incorporated in the cast bronze head of the each lantern where it is suspending from the bracket. This case head is connected to a second bronze casting which carries the glazed framework by means of an inner spider of aluminium alloy and bronze. The space between the two castings is enclosed by a spun bronze dome. The entire glazed framework swings clear on a hinge to give access to the internal refracting glasses and lamps. The external framework is glazed with a specially selected diffusing glass of low absorption and high quality. The internal refracting units are comprised of three pieces of prismatic glassware, two of which are hermetically sealed together in the form of an inverted bowl with a cavity between its internal and external surfaces, together forming the upper member of the unit. The mouth of the bowl is couvered by the third glass which is shaped like a deep dish. These units form a casing approximating to spherical in shape around the light source or lamp. While practically the entire external surfaces of the refracting units is smooth, the internal surfaces are cut into a series of prism groups whic hrefract or bend the light emitted by the lamps and direct it over the road surface as required through the external diffusing glass panels of the lantern.

302 Lantern
Holophane 302 Street Lighting units have been designed in accordance with the requirements of BS/ARP 37 for street lighting under war-time conditions. The general level of illumination provided by the specification is 0.0002 ft. candle and nowhere on the road shall the illumination exceed 0.0004 ft. candle. The B.S. specification publishes three sets of limiting vertical light distribution curves and any lantern used for street lighting must be within the limits of these curves. The lanterns give a relatively uniform illumination along the road and should not be spaced at less than 100' apart. The smallest GLS available is 15W which gives a mean spherical candle power of 10, so that it is required to provide a fitting which will reduce the bare lamp intensity at 75° by one-tenth and at 0° by over a sixtieth. This is accomplished in the 302 by a method which is provisionally protected by patent No. 32075/39. The unit consists of a partially obscuring cylinder placed around the source in combination with a secondary baffling member in the form of an inverted cone. The lower section of the cylinder is so constructed as to allow the spcified intensity to be emitted at angles from about 65° to 85° to the vertical while the function of the combination, cylinder and cone, provide the very subdued general intensity required at angles below 65°. At the base of the cylinder is formed a flanged opaque cup which is fixed in a definite position relative to the lamp filament. The fitting is completed with a bowl shaped reflector giving a cut-off at about 85° from the vertical. The unit gives a large area of low luminosity that is a distinct aid to vision.

302 Lantern
An improved design after experiences during the winter of 1939. The prismatic glass dish, smooth outside, having vertical diffusing prisms round the rim, the remainder being rendered opaque on the inside, is mounted in a heavy guage steel sheet unit. This is in two main parts, a body to which is attached an assembly consisting of a reflector carrying the glasses with a perforated metal ring behind it and an inside white reflector all of which is detachable in one piece by releasing three wing nuts. A cast top is provided which is tapped to screw on the shade carrier lampholder wen required for existing lanterns. As an alternative a sheet metal disc can be fitted for the conversion of existing lanterns. As a complete lantern, a special cast top is avilable which is tapped ¾" gas, and fitted with a porcelain lampholder. The unit takes 25W pearl lamp for the 20' mounting height or 15W pearl lmap for 15' or 10'. The metal work is finished in black vitreous enamel.

dilux lantern / 330 series
A new development (in 1947) in street lighting technique employing horizontally-burning Mercury Discharge Lamps, in conjunction with a highly efficient optical system providing semi-cut-off light distribution characteristics.

The high intrinsic brightness of the light source is shielded by the reflector assembly in the lantern hood, thus avoiding glare conditions, while the combined reflector refractor assembly affords a controlled two-way non-axial distribution, promoting adequate road surface and background brightness when installed in accordance with Group "A" requirements.
