Description

Signal lamp

The invention relates to a luminous element, especially a lamp, especially for a lamp signaling according to the preamble of claim 1.

Traditional light elements have a socket and a bulb arranged in it, in which it is subjected to current, for example, a tungsten wire in an atmosphere of noble gas and thanks to the corresponding thermal effects, emits electromagnetic waves in the area of the visible spectrum, that is, light. However, luminous devices of this type result expensive, appalling and harmful to the environment in manufacturing and have an unsatisfactory short lifespan. In addition, the performance It is not good either.

So far discharge lamps have been proposed Soda with the corresponding caps as improvement. Without However, these require a high initial voltage and the corresponding control signal for maintenance of the gas discharge that generates light. Moreover, they are necessary luminescent substances, since electromagnetic waves generated directly by the gas discharge are not generally in the area of the visible spectrum. Lamps of this type additionally they need a bulb in which the gas discharge, as well as an electronic control system included in the bushings, which requires a space of respective large construction. Moreover, the lamp needs a long period of time until the gas discharge reaches a full nominal light intensity.

Under all the aforementioned inconveniences Previously, this type of gas discharge lamps with socket are not indicated, for example, for lamps signaling.

For the document DE-U-94 17 300 a lamp is known signaling with a luminous element with a socket and a luminous body arranged in it, comprising the luminous body a printed circuit board with most of the diodes luminous arranged in it and presenting the circuit board printed one foot, which extends along a predetermined path inside the socket and the light-emitting diodes in the printed circuit board, so that they emit waves electromagnetic in the area of the visible spectrum in different directions with respect to the printed circuit board.

In addition to the use of two LEDs with opposite directions of emission, the use of three diodes is also expected luminous, these being arranged horizontally in a plane with three emission directions approximately in the form of a cross. Diodes luminous are arranged horizontally on the circuit board printed, not providing any other LED vertically perpendicular to the other LEDs, so that an omnidirectional light effect cannot be achieved. To this it should be added that the lamp socket has been designed so which can be replaced in a lamp nozzle configured in the Luminous body with a bayonet fastener.

For the document DE-A-39 16 875 a lamp is known multi-camera signaling consisting of an open housing ahead with a stage installed inside, from sources luminous arranged in it, as well as an optical arrangement established by the light sources and a final light plate which closes the housing in front, using LEDs that they are equipped with condensing lenses that are arranged respectively in front of the surfaces that emit the light.

The document DE-U-93 13 403 describes a lamp, especially for use in optical devices signaling, which is composed of a housing that expands essentially conical shape of a screw cap standardized on a rotationally symmetric conical centerpiece with respect to the axis of the bushing, in which it is arranged perpendicular to the axis of the bushing, the stage that carries the field of light-emitting diodes or light-emitting diode chips, and in the that the housing, on the visible side, is transparently closed by means of a dispersion crystal.

According to the document EP-A-0 108 368 a known optical alarm or indication device with LEDs which is composed of a circular or polygonal shaped base plate, whose edge and center are equipped with different LEDs colors and in which a common molding resin body wraps around LEDs, so that this forms the motherboard, as well as a supplementary threaded part for fixing the device. In This device, the LEDs are arranged on the edge of a circular or polygonal plate and are surrounded by a lid of protection.

The document DE-U-297 12 229 describes a body of lighting for luminous signaling equipment that is composed of a series of light emitting diodes electrically conductive to the standard connection adapter through of power lines by means of a rectifier arranged in the Lamp housing and a transformer. In this case, the diodes luminous are arranged evenly distributed on a surface flat or convex domed front of the lamp housing, filling the existing cavities between them and the wall of shell with a heat resistant synthetic resin. Here the lamp housing can have a completely different shape depending on the application, for example, an elliptical form, a form of pear, conical shape or truncated cone shape, can be configured this also with a circular cylindrical shape several times staggered

The document DE-A-34 30 540 describes a luminous application consisting of a housing, arranged in the housing a luminous stage in which they are placed, in one of the sides, luminous components and connect, on the other side, two electrical conductors, completely sealing the luminous stage, luminous components and electrical conductors in the housing in an insulating molding resin.
