Abstract

Has a swinging or gyrator or other type of movable support (1) which holds bulbs in use (2) fixed inside a lamp reflector (4), together with replacement bulbs (3). The bulbs are linked to an axis (5) actuated manually, mechanically or automatically. Movement of the axis allows the substitution of a bulb or a group of bulbs with replacements (3). The lamp supply is routed through spherical type contacts (8) which connect a part of the circuit (6) to the lamp (4) and the other part of the circuit (7) is connected to the support which allows disconnection of the blown bulb(s) and connection of replacement bulb(s) when the support is moved by the axis. The system can be automated using a sensor which detects any electric current change.

Description

The aim of this invention, as it is stated here in this memoir description consists of a safety device with luminaires.

Now, changing the bulb of a headlight must be done manually, a sometimes complex operation: disassemble the headlight, replace the burnt bulb with a new one. Once the new bulb is installed, you must reassemble the lighthouse in place.

From the moment the bulb burns until the end of the replacement process, the light source remains off.

Often a burnt bulb can temporarily neutralize a source of light at a critical moment or for a long period of time. This lapse of time, especially with regard to emergency lighting, lighting vehicular, street lighting, traffic lights, etc., must be the minimum possible.

For these reasons we have developed this new safety device changing light bulbs, adaptable to any type of installation bright, minimizes the replacement time of burnt bulb and allows the supply of new bulbs occurs at a most adequate.

This new system is mainly composed of a movement support tilting, oscillating, rotating or straight, or accommodates two or more bulbs which take position sequentially or alternately in the luminaire as long as the use bulb burns.

This support can have various shapes, depending on the quantity of bulbs to to house, of the movement which is carried out to set up the new bulb and the system that transmits this movement.

Another possibility would be that of transmitting the movement to the support at by means of an axis connected to it, which can have different orientations. Two preferably: one perpendicular to the direction of illumination or the other in the same direction. The orientation of the axis, or axes, is a factor determining for the shape of the bulb holder support.

This axis transmits the movement to the support which installs the new bulb in the lighthouse, on the grill of the usual one. The support keeps this position until a new change of bulb (s). This movement can be gyratory or straight.

To light (or switch on) the new bulb, you need a system power supply based on contacts that connect a branch connected to the headlight and another connected to the support, to thus close the supply circuit bulbs.

These contacts, which can be spherical or in any other way; disconnect the bulb burned thanks to the movement impulsed to the support, and branch the new bulb (s) of use, the only ones powered in order to avoid all possibilities of short circuit.

The axis can be started in several ways the simplest of them manually using a joystick or lever that the user operates when the light bulb burns out, or mechanically at through a network of sheathed cables or by a small motor connected to the axis which would be activated by a push button or other means of contacting.

Optionally this device can include a starting system completely automatic, more complex than those described above, but very useful in the case of lighthouses with restricted access. This system is mainly composed of an electric rupture detection sensor bulb, for example from a circuit ammeter, and triggers the bulb replacement process.

The benefits of this new system include minimizing the time required to renew the lighting and, depending on the start-up system, full process automation, reduced to minimum lapse of time during which the light source remains off.

This new device also makes it convenient and easy the supply of new bulbs during more circumstances adequate, for example during the day when the headlight is not on, only immediately breakage of the bulb when the light from the lighthouse is necessary.

DESCRIPTION OF THE FIGURES

DESCRIPTION OF A PRACTICAL CASE

The new replacement light bulb system is mainly composed of a tilting, gyratory or straight support (1), which may have several shapes, where two or more bulbs are housed. A of which is the one in use (2) and the others the spare ones (3) and which are installed sequentially in the headlight (4) during the toasting of that of use (2).

The bulb holder support (1) is assembled to an axis (5), or any other motion transmission system, and may also have different orientations, preferably two: one perpendicular to the direction of enlightenment, the other in the same direction.

This axis (5) transmits the gyratory movement to the support (1) which installs the spare bulb (3) in the headlight (4) when the bulb burns out of use (2) and maintains this position until a new change of the bulb. The burnt bulb remains disconnected.

For lighting the use bulb (2) a power system is required composed of contacts which link part of the circuit (6) connected to the luminaire (4); the other part (7), connected to the support (1) closes the supply circuit of the bulb in use (2).

The contacts (8), which can be spherical or of any other type, disconnect the burnt bulb by movement of the support (1), actuated motion transmission system, here axis (5), and reconnect the new use bulb, the only one powered to always avoid any possibility of short circuit.

Starting the axis (5) or the motion transmission system employee can be activated in many very different ways: manually, mechanically or automatically.

Established the stated concept, follows the mention of claims summarizing the new things that we want to describe and protect.

Claims (3)

LIGHTING SAFETY DEVICE, of the type adaptable to headlights, street lights, etc., essentially characterized to be composed of a tilting, gyratory, or other support (1) which houses one or more used bulbs (2), located at the lighthouse interior (4), with spare bulbs (3), subject to an axis (5) which operates manually, mechanically or automatically, to transmit a movement, which allows to replace the bulb or group d 'burnt bulbs in use (2) with spare bulbs (3), thanks to the support (1). SAFETY DEVICE IN LUMINAIRES, according to the preceding claim, characterized because it has a supply system for the used bulb (2), through contacts (8), which can be spherical, which unite a part of the circuit (6) connected to the headlight (4) and the other part of the circuit (7) connected to the support (1), producing the disconnection of the burnt bulb and the branching of the new bulb when the movement of the support (1) impelled to the axis (5). LIGHTING SAFETY DEVICE, according to the preceding claims, characterized because , optionally, can present an automation of the actuation system of the axis (5) from a sensor which detects the change of amperage and causes the spare operation. The sequence or order of movements, that is to say the supply and activation of the movement, can vary according to the characteristics of each of the components.
