Un thermostat 29 de sécurité est prévu pour contrôler la température à l'intérieur du ballon 10, et interrompre automatiquement l'alimentation de l'ampoule 22 en cas d'arrêt accidentel du ventilateur 15.A safety thermostat 29 is provided for controlling the temperature inside the balloon 10, and automatically interrupting the supply of the bulb 22 in the event of an accidental shutdown of the fan 15.

Le matériau en polycarbonate du bol 25 renferme de préférence des agents chimiques protecteurs qui le rendent insensible au rayonnement ultra-violet. La transparence du bol 25 n'est pas altérée dans le temps, et permet d'obtenir un champ d'éclairage uniforme et exempt de zones d'ombres.The polycarbonate material of the bowl preferably contains protective chemicals which render it insensitive to ultraviolet radiation. The transparency of the bowl 25 is not altered in time, and provides a uniform illumination field and free of shadows.

La présence du bol 25 en matière plastique moulée procure d'autre part une double fonction d'écran isolant antidéflagrant en cas d'explosion accidentelle de l'ampoule 22, et de déflecteur de l'air de soufflage pour le gonflage de l'enveloppe 11 par le haut.The presence of the molded plastic bowl 25 also provides a dual function of explosion-proof insulating screen in the event of an accidental explosion of the bulb 22, and a deflector of the blowing air for inflating the envelope. 11 from the top.

Pour démonter l'enveloppe 11, il suffit d'enlever l'organe de fixation 27, et de tirer l'enveloppe 11 vers le haut, après un dévissage préalable des vis de fixation au niveau de la platine 18. L'ouverture 14 de l'enveloppe 11 quitte le rebord 26, et permet l'échappement total de l'air emprisonné dans l'enveloppe 11. Il n'est pas nécessaire d'arrêter l'alimentation de l'ampoule 22 et du ventilateur 15 durant ce démontage de l'enveloppe 11. L'ampoule 22 peut donc rester allumée durant cette opération de remplacement de l'enveloppe 11 qui est très rapide.To remove the casing 11, simply remove the fastener 27, and pull the envelope 11 upwards, after a prior unscrewing of the fastening screws at the plate 18. The opening 14 of the casing 11 leaves the rim 26, and allows the total escape of the air trapped in the casing 11. It is not necessary to stop the supply of the bulb 22 and the fan 15 during this disassembly of the envelope 11. The bulb 22 can therefore remain lit during this operation of replacing the envelope 11 which is very fast.

En fonction du volume de l'enveloppe 11, on peut utiliser des ampoules de différentes puissances allant jusqu'à 2000W, et de différentes tensions.Depending on the volume of the envelope 11, it is possible to use bulbs of different powers up to 2000W, and different voltages.

Sur les figures 5 et 6, le système d'éclairage 12 comporte plusieurs ampoules 22 électriques, par exemple quatre, logées dans des douilles 23 isolantes à l'intérieur du bol 25. Le volume de l'enveloppe 11 et du bol 25 est plus grand que ceux de la figure 1 à ampoule unique.In FIGS. 5 and 6, the lighting system 12 comprises several electrical bulbs 22, for example four, housed in insulating bushings 23 inside the bowl 25. The volume of the envelope 11 and the bowl 25 is larger. larger than those of Figure 1 to single bulb.
