Description

Luminary.

OBJECT OF THE INVENTION

The object of the present invention relates to a luminaire constructed with LED technology that allows its use in an existing luminaire by replacing the conventional luminaire, more specifically it is intended to replace conventional T5 toroidal fluorescent tube luminaires.

Find special application in the field of lighting industry.

TECHNICAL PROBLEM TO BE RESOLVED AND BACKGROUND OF THE INVENTION

The technology of light generation by means of light emitting diodes (LED) (light emitting diode) allows a very important energy saving compared to other existing lighting technologies because these LED devices generate light from electric energy with higher performance in terms of lumens per watt and with higher quality in terms of color rendering. Another important advantage of LED technology is that the life of the devices is much longer, with values around fifty thousand hours of use, which also represents an economic advantage. Some of the other available technologies are: incandescent luminaires, fluorescent luminaires, high pressure mercury vapor luminaires, high or low pressure sodium vapor luminaires, metal halide luminaires.

Due to the aforementioned economic advantages, there are numerous developments that have been made to solve different lighting applications using LED devices.

One of the possible applications is the use of LED devices in indoor luminaires instead of fluorescent tube luminaires. There are numerous commercial products for direct replacement of straight fluorescent tubes with tubes constructed using LED technology. There are also commercial LED tubes for

replacement of toroidal fluorescents of section "T9" (diameter 28.6mm).

However, there is no direct replacement of tubes constructed using LED technology for toroidal fluorescent tubes of section “T5” (15.9mm diameter), because the small volume prevents adequate dissipation of the heat generated by the LED devices. When it is intended to replace a toroidal fluorescent tube of section "T5", it is not possible to maintain the size of the original fluorescent tube.

EP 2151620 A1 is known in the state of the art as a light emitting LED tube formed of transparent plastic and a metal heat sink that includes welded LEDs on a metal printed circuit board core. All LEDs are inserted directly into the metal core printed circuit board with a single insulating coating to allow the anode and cathode of the LED to be inserted into the metal core printed circuit board and welded on the opposite side of the printed circuit board of metal core.

Therefore, the present invention comes to solve the aforementioned prior art problems.

DETAILED DESCRIPTION

The present invention comprises a luminaire (1) constructed with LED technology to be used in substitution of T5 toroidal fluorescent tubes in those luminaires that allow it, since their dimensions are not the same.

The luminaire (1) has been specifically designed for those applications where the number of luminaires (1) installed is very high and it is necessary to regulate the light intensity of the luminaire assembly (1) by means of a remote control system. As a communication procedure between the remote control system and the luminaires (1), a network through wireless communications via infrared light has been chosen.

The luminaire (1) comprises:

-

a plurality of LED devices (2,3) arranged on a plurality of printed circuit boards (5) interconnected with each other and arranged so that the assembly forms a circular crown, - the plurality of printed circuit boards (5) are fixed on a plurality of heat sink modules

(6) identical interconnected also with a circular crown shape, where each printed circuit board (5) comprises:

or a plurality of visible light emitting LED devices (2),

or a plurality of infrared light emitting LED devices (3),

or an infrared receiver (4) for receiving control commands from the system

of remote control directly or through the luminaires (1), -a control element (14) by microprocessor external to the luminaire (1) that:

-

 receives control commands from the infrared receiver (4) of the luminaires (1),

-

issues control commands to the visible light emitting LED devices (2) to regulate the light emitted by the luminaire (1),

-

 issues control commands to infrared light emitting LED devices (3) for communication with the rest of the luminaires (1),

-

The plurality of heat sink modules (6) comprises:

or a first flat face, on which the plurality of printed circuit boards (5) are fixed, and

or a second face with a plurality of cylindrical elements (8) to increase the dissipation surface and favor the cooling of the luminaire (1),

-

a semitoroid shaped cover (7) that protects the plurality of printed circuit boards (5) together with the LED devices (2,3), isolating them from the weather and that blurs the light emitted by the LED devices (2,3 ), wherein said cover (7) comprises fixing parts (15) to the plurality of printed circuit boards (5),

where each luminaire (1) receives commands from a remote control system or other luminaires (1) and in turn transmits them to other luminaires (1). In this way, a very large number of luminaires (1) can be controlled via a network via wireless communications via infrared light.

The control element (14) of the luminaire (1) is externally housed in the luminaire (1) to avoid overheating due to the heat produced by the LED devices (2,3).

In a preferred embodiment, the number of printed circuit boards (5) is three and they are flat.

It is required that the distance between luminaires (1) be compatible with the propagation characteristics of infrared light between said luminaires (1). The infrared light will typically propagate from one luminaire (1) to another luminaire

(1) by reflection on the ground, in a non-directional way, as can be seen in Figure 6.

For this reason, the infrared light emitting LED devices (3) must be powerful to achieve a better distribution of the emitted infrared light.

This type of luminaires (1) are installed on the ceiling next to each other. The infrared light emitting LED devices (3) of the luminaire (1) emit in all directions where part of this infrared light is reflected on the ground going to the adjacent luminaire (1), thus allowing communication.

Each heat sink module (6) is fixed to two other heat dissipation modules (6) adjacent by means of screws (11), fitting stepped edges (9) of a heat sink module (6) with the stepped edges (9) of the adjacent heat sink modules (6), as shown in Figure 3.

In a preferred embodiment, the number of heat sink modules (6) is six, metallic and made of aluminum to facilitate heat dissipation.

The plurality of heat sink modules (6) comprise holes (13) that allow the plurality of printed circuit boards (5), which in turn comprise holes (12), to be fixed to said heat sink modules ( 6) by correspondence of the holes (12, 13) through screws of the printed circuit board (10).

The plurality of heat dissipation modules (6) also comprise end holes (16) which, by means of screws of the heat dissipation modules (11) allow to interconnect some heat dissipation modules (6) with others.

 By fixing the printed circuit boards (5) to the heat dissipation modules (6), the pressure exerted by said printed circuit boards (5) on said heat dissipating modules (6) allows for adequate thermal contact.

It is possible to use a transparent cover (7) that does not perform the blur function when it is not necessary.

The present invention should not be limited to the embodiment described herein. Other configurations can be made by those skilled in the art in view of the present description. Accordingly, the scope of the invention is defined by the following claims.
