FR2897414A1 - Public or residential lighting lantern for maintaining e.g. metal-iodide lamp, has base integrating temporized reverse current relay to operate alternatively discharge and LED lamps for direct lighting towards ground or indirect lighting - Google Patents

Abstract

The lantern has a socket cap (1) for receiving LED lamps (4), and a direct or indirect light distribution block (2) for receiving discharge lamps (9). A hollow tube (5) connects the cap to a base (3) for allowing passage of power supply leads of the LED lamps. The base integrates a temporized reverse current relay (6) to operate alternatively the discharge and LED lamps, for a defined period, for direct lighting towards ground or for indirect lighting.

Description

The present invention relates to a system enabling the use of a

  residential or public lighting lantern in dual optical version. For lighting in residential or public outdoor lighting, to date only single-source direct, indirect or direct / indirect solutions are used.

  The search for savings in consumption, spacing of maintenance interventions, are important criteria in the calculation of the cost of a lighting installation, as much for a community as for a particular user. The device according to the invention overcomes this problem. It comprises two different lamps, one with discharge installed in the optical unit, the other with Leds adapted at the periphery of the cap, under-face for a direct lighting towards the ground, or incorporated in the optical block in indirect lighting version . Leds lamps can be used in different colors and power adapted to the desired illumination result. In order to allow fully automatic operation, a timed reversing relay will allow the two lamps to operate alternately for a defined period of time. Through the use of this system, it is maintained a minimum security and traffic lighting for marking a space or a road. A timed reversing relay allows the two lamps to work alternately, cuts off the main lamp and automatically switches to the power supply of the LED lamps, over a defined period, with a return to the initial state also automatically. Leds lamps can be used on all colors available on the market. A timed reversing relay can be adapted directly into the base of the lantern for individual control or globally on the start of the supply line of a lantern group. A device composed of a hollow tube connects the base to the cap and allows the passage of the wires feeding the LED lamps. According to particular embodiments: The hat can be adapted to an existing lantern to create a complement of _ range. _ An entirely manufactured original product is feasible. The powers of the main source and LEDs vary according to needs and demands. The accompanying drawings illustrate the invention: FIG. 1 represents in section the principle of the invention.

  Figure 2 shows the hat seen from below with integration of LEDs on the periphery. Figure 3 shows in section the principle of a lantern with fully indirect light distribution. Figure 4 shows the lantern seen from above, without a cap, with integration of LEDs around the optical unit for a version with totally indirect distribution.

  With reference to these drawings, the device comprises a cap (1) receiving the LED lamps (4). An optical block (2) with direct, indirect or direct / indirect light distribution. It can be used as needed, discharge lamps (9) of different models, metal Iodide, Sodium High Pressure, Mercury, Fluo-compact, and adapted powers.

  The base (3) integrates the delayed inverter relay (6), the Leds converter (7) and the power supply (8) of the main lamp (9), and adapts to commercially available supports. The timed reversing relay (6) can be adapted from the supply line out of the lantern. A hollow tube (5) connects the cap (1) to the base (3) in order to allow the passage of the supply wires 10 of the LED lamps (5). This tube can be doubled, tripled or more for a question of uniformity of the whole. The hat (1) can have various forms for various finishes both aesthetically and technically. The constituent materials of the lantern are: for the cap (1) either molded aluminum, polycarbonate, methacrylate or composite materials. For the diffuser (10), either polycarbonate, methacrylate or glass, for the optical block (2) of aluminum or glass. The base (3) will be either polycarbonate or cast aluminum. The diffuser (5) may not be used, this in the case of a wholly indirect light distribution lantern. For this solution, FIG. 3 shows a variant solution 20 where the sealed optical block (2) is incorporated into the base (3), in this case the LED lamps (4) are installed around the optical block (2) with a light distribution. indirect.

Claims (3)
