The invention also produces ignition. Simultaneous diodes to produce a flash effect.

In general the invention is applicable in any sector of the technique in which generation is required of rotating lighting, and more specifically in alarms and emergency vehicles

Background of the invention

In the state of the art the employment is known of lighting devices that cause the emission of flashes of flashing light by means of a lamp around which provides a rotating parable, so that at turn on the lamp and the rotation of the parabola occurs produces the emission of flashing light flashes.

Lately this function is performed with a set of LED diodes, which have lower consumption, and which emit light at 360º simultaneously to achieve the emission of flashes

Although in the state of the art the  effect of governing the sequential ignition of different diodes LED to achieve different optical effects, does not exist in the light emitting devices used in vehicles of emergency, a device that produces a rotating effect.

Description of the invention

In order to achieve the objectives and solve the aforementioned drawbacks, the invention provides a new lighting device for signaling, which, like the lighting devices provided in the prior art, comprises at least one printed circuit board in which it is included at least one reflector and a plurality of LED diodes arranged forming a curve to emit flashing light flashes, in accordance with the curve described by the LED diodes. The novelty of the invention is that the reflector comprises a curved portion that adapts to the curve formed by the LEDs, so that said curved portion comprises, in correspondence with each LED, a reflection concavity of the light emitted by the corresponding LED diode. In addition, the lighting device comprises a power control circuit of the diodes to turn them on and off sequentially so that the lighting thereof generates a light effect.
rotary.

In a preferred embodiment of the invention,  provide at least two printed circuit boards with the corresponding reflector and LEDs, so that each set of these elements are arranged vertically aligned to Determine different levels of lighting.

In an embodiment of the invention the Different lighting levels are of different colors, for comply with the various existing signaling regulations.

It is also expected that LEDs can present different levels of light intensity to get different effects

In the preferred embodiment of the invention the printed circuit board presents a circular configuration on which the diodes and the reflector are located with this same configuration, but obviously they can also adopt any other configuration, such as a "U" configuration.

In the preferred embodiment of the invention, the  reflector is equipped with a cylindrical section that includes the reflection concavities arranged in correspondence with each diode, and the one that follows a section of inclined wall and slightly curved that goes outside forming a stretch approximately conical. In the case where the diodes are arranged according to one. U-shaped reflector it comprises a "U" section in which the corresponding reflection cavities arranged in correspondence with each of the diodes and the one that follows a section inclined and slightly curved wall that goes outside forming a kind of "U" wing.

This described configuration allows the junction of the free edges of two reflectors to form the different lighting levels, so that in the part upper and lower are each of the plates of printed circuit with its corresponding diodes and then the two reflectors joined together by their free edges.

The invention also provides that the control circuit feeds a certain number of the LEDs that make up the curve, to illuminate a segment thereof. The possibility that the control circuit feeds the LEDs simultaneously to produce an effect is also contemplated.

Description of the preferred embodiment

Below is a description of the invention based on the figures discussed above.

The device of the invention is constituted by a printed circuit board 1 which in the embodiment example of figures 1 to 3 presents a circular configuration, on the that a plurality of LEDs 2 have been arranged forming a circle, completing the whole set with a reflector 3 that is equipped with a cylindrical portion 4 that adapts to the circle that they form the LEDs 2, so that in correspondence with each one of said LEDs 2 the cylindrical portion 4 comprises a concavity 5 of reflection of the light emitted by the corresponding LED 2 which is located in correspondence with said concavity 5.

The cylindrical portion 4 continues along a section inclined and slightly curved wall 6 that is directed towards the exterior forming an approximately truncated conical section.

The device is complemented by a control circuit (not shown) that governs the switching on and off of LEDs 2 sequentially, so that they cause a light effect

In figure 3 two devices are used as those described in figure 1, aligned vertically to Determine different levels of lighting. For this, the free edges of reflectors 3 establishing a set with Two levels of lighting. In this case a circuit of control to govern the on and off of each of the 2 LEDs, but two or more circuits can also be used of control, according to needs

In another embodiment of the invention the plate printed circuit is presented by a "U" configuration of so that the LEDs 2 are arranged with the same configuration and reflector 3a presents a configuration also in "U".

In this case the cylindrical portion 4 of the Figure 3 is a "U" portion 4a that incorporates a concavity 5 in correspondence with each of the LEDs 2 for produce the reflection of the light that they emit as in the last case.

In addition, as in the previous case, the U-shaped portion 4a extends along a section of wall inclined and slightly curved 6a that goes outside forming a wing determined by approximately a section in "U" 6a.
