Title (EN) TLD LOW-PRESSURE GAS DISCHARGE LAMP
(FR) LAMPE À DÉCHARGE DE GAZ À BASSE PRESSION TLD
Abstract: front page image
(EN)The invention relates to a low-pressure mercury vapor discharge lamp (2,4)having a first vessel (6) enclosing a discharge space, and a second vessel surrounding the first vessel. The second vessel (22) comprises a polymer material, or the second vessel (16) comprises a glass material and is at least partially coated with an infrared-reflective material (18) on the side facing the first vessel. A stagnant layer of gas is created between the first and the second vessel, reducing the heat transfer from the discharge space to the surrounding area of the lamp. As a result, the light output is improved at relatively low ambient temperatures.
(FR)L’invention concerne une lampe à décharge à vapeur de mercure à basse pression (2, 4) comportant un premier récipient (6) entourant un espace de décharge, et un second récipient entourant le premier récipient. Le second récipient (22) comprend un matériau polymère, ou le second récipient (16) comprend un matériau de verre et est au moins partiellement revêtu d'un matériau réfléchissant l'infrarouge (18) sur le côté faisant face au premier récipient. Une couche stagnante de gaz est générée entre le premier et le second récipients, réduisant le transfert de chaleur depuis l’espace de décharge vers la zone entourant la lampe. Par conséquent, le rendement lumineux est amélioré à des températures ambiantes relativement faibles.
