The present invention relates to lamps intended for continuous use such as, for example, votive lamps.

As is known, open flame votive lamps are not allowed, and in their place common incandescent bulbs or electronic candles are used.

ΛζΙ battery.

Incandescent bulbs require an electrical system with a connection point for each user and require a supply contract with relative fixed costs. The lights and battery solve these problems but have a limited duration, they can pollute the environment in case of loss of active material from the battery, and their

light is not as "warm" as that of a light bulb or flame.

The purpose of the present invention is to remedy the aforementioned drawbacks and therefore to propose a lamp intended for continuous use provided with a highly efficient charging system, of practically unlimited and ecological duration.

Another object of the invention is to provide a votive lamp capable of emitting a light in a random sequence that reproduces the visual effect of a flame whose fluctuation is unpredictable and constantly variable.

Said purposes are achieved with a lamp, particularly intended for continuous use, such as the votive one, comprising a solar panel, at least one rechargeable battery through the current generated by said solar panel, an electronic circuit powered by said battery, and at least one emitter diode of light controlled by said electronic circuit.

Further details of the invention will become clearer from the following description made with reference to the accompanying drawings, indicative and not limitative in which:

Fig. 1 shows, in perspective view, an example of a votive lamp according to the invention;

Fig.2 shows the lamp in front section; And

Fig. 3 shows the lamp in lateral section.

This description refers to an example of a votive lamp having a square-shaped body 11, like a frame, with a central opening in which a lighting source 12 is placed, for example a pyramid shape. The invention is however applicable to any form of lamp, also intended for uses other than the votive one.

On the top of the body 11 there is a solar panel 13, preferably of amorphous silicon, intended to generate a current of intensity proportional to the intensity of the solar radiation. The body 11 houses a pair of rechargeable alkaline batteries 14, connected to the solar panel 13, and an electronic circuit 15 powered by these batteries. The electronic circuit 15 commands and controls the ignition of the lighting source 12 which consists of a pair of high efficiency light emitting diodes ("LEDs"). A peculiarity of said electronic circuit is that of turning on the diodes according to a pseudo-random sequence, also operating with voltages lower than one Volt and with very low rising gradients. This allows you to avoid the use of special reset circuits that lead to unwanted consumption and increase the number of components used.

The electronic circuit 15 is also provided to limit the charge of the batteries 14 in the event of very intense lighting so as to avoid overheating, and to prevent the
