Patent

CA 2466175

Lighted reading glasses (5) are provided to enable clear reading of normal sized text to occur when the reading material (10) is held at usual distances from the reader in poorly lit locations. The lighted glasses have high intensity lights, such as in the form of LEDs (108) that generate narrow light beams cones and which are oriented in light modules to inwardly cant the light beam cones to meet and overlap so high brightness light is generated in a conical overlap area of light which is maximized in size in the range of normal reading distances. In another form, a clip-on light apparatus is provided that includes a spacer frame having opposite end portions each mounting lights, preferably constructed as described above. In one form, retainers at the end portions are adapted to releasably engage outer sides of the eyeglass lenses. The frame preferably incorporates a draw spring assembly to allow adjustments for different size glasses. In another form, the light spacing is fixed and a clipping mechanism is provided for clipping to the eyeglasses in the area generally between the eyeglasses lenses.

L'invention concerne des lunettes de lecture ~clairantes permettant de lire clairement un texte de taille normale lorsque le document est maintenu ~ distance normale du lecteur, dans de mauvaises conditions d'~clairage. Les lunettes selon l'invention comportent des lumi­res de haute intensit~, sous forme de DEL par exemple, qui produisent des faisceaux lumineux ~troits en cÙne et qui sont orient~es vers l'int~rieur dans des modules lumineux, de sorte que les faisceaux lumineux en cÙne se rencontrent et se chevauchent pour produire une lumi­re ~ haute intensit~ dans une zone de lumi­re ~ chevauchement conique dont la taille est augment~e au maximum sur une ~chelle de distances de lecture normales. Un autre aspect concerne un appareil lumineux clipable comprenant un cadre espaceur constitu~ de parties extr~mit~s oppos~es pourvues de lumi­res de montage, construites de pr~f~rence selon la description ci-dessous. Dans un autre aspect, des dispositifs de retenue situ~s au niveau des parties extr~mit~s sont con×us pour venir en contact amovible avec les cÙt~s ext~rieurs des verres des lunettes. Le cadre comprend de pr~f~rence un ensemble ressort ~tir~ permettant le r~glage des lunettes selon diff~rentes tailles. Dans un autre aspect, le dispositif d'espacement lumineux est fix~ et un m~canisme de clip est dispos~ de sorte ~ Útre clipp~ sur les lunettes, dans une zone g~n~ralement situ~e entre les verres.
