| titleOfInvention | Low-pressure discharge lamp |
| abstract | The invention relates to an improved low-pressure gas discharge lamp comprising a gas discharge vessel (1) surrounding a discharge space (2), containing a gas filling, and further comprising means to generate an electromagnetic field (3) and means for generating and maintaining a low-pressure gas discharge. The lamp is characterized in that the discharge lamp is provided with a first phosphor coating on a surface of the gas discharge vessel and with a second phosphor coating, the second phosphor coating being provided on a surface of the lamp that is more remote from the discharge space compared to the first phosphor coating, and the first phosphor coating being selected from the group of thermally stable phosphors. The low-pressure discharge lamp provides increased efficiency and reduced solarisation as compared to commercially available low-pressure discharge lamps. |
