11490473 · 2022-11-01 · ·

In an apparatus for thermal treatment of substrates, a gas discharge lamp runs in a simmer mode in standby operation. A constant power supply may be connected to the gas discharge lamp via a first switch. At least one charged capacitor may be connected to the gas discharge lamp via a second switch. A thermal treatment of the end side of a substrate with a duration of between 20 milliseconds and 500 milliseconds is provided in a manner governed by light absorption. This time window is advantageous for thermal treatment of coatings having a thickness of 2 to 200 micrometers, wherein the temperature of the rear side of the substrate can remain below that of the end side. The temperature on the end side can be significantly increased by the gas discharge lamp being connected to the capacitor via the second switch at the end of the time window.

Low-frequency compact air-cavity electrodeless high intensity discharge lamps

Electrodeless high intensity discharge lamps have the promise of higher reliability and higher efficiency than traditional electroded high intensity discharge lamps. However most electrodeless HIDs operate in the frequency range of around 400 MHz to 2.5 GHz resulting in expensive, inefficient RF drivers that reduce the overall efficacy of the lamp. Operating the lamp at lower frequencies results in substantial increase in the size of the resonators used in traditional electrodeless HIDs. In this invention a novel design is used to lower the operating frequency of the resonator without increasing the size of the resonator. This provides an avenue to increase the conversion efficiency of the RF driver and the efficacy of the lamp system.
