<p>A microwave powered electrodeless lamp (10) includes an improved screen unit (20) having mesh section (42) and solid section (43). An internal reflector (50) is secured at the juncture of the two sections (42, 43) so as to reflect light emitted from a bulb (21) located in the mesh section (42). Light emitted from bulb (21) is prevented from entering the solid section (43) by the reflector (50) secured at the juncture of the two section (42, 43). The reflector (50) is mounted in the screen unit (20) by bendable tabs (47, 48)arranged to define parallel support planes which support opposite surfaces of the reflector (50). The mesh section (42) and tabs (47, 48) are preferably formed by etching a thin metal sheet (41).</p> |
