Abstract: A burner (10), particularly for vehicle heaters, includes a flexible panel (12) that separates an inner combustion region (14) from an outer region (16). A light-sensitive sensor for flame recognition is arranged in the outer region (16), and the flexible panel (12) includes at least one light opening (20) that allows the passage of light from the inner combustion region (14) into the outer region (16). The light opening (20) also allows the passage of combustion air from the outer region (16) into the inner combustion region (14).

Abstract: Burner (10), in particular for a vehicle heater (12), having an orifice plate (14) separating an inner combustion region (16) from an outer region (18), wherein a photosensitive sensor (20) is arranged in the outer region (18), wherein at least two separate air inlet openings (22, 24, 26, 28) are being provided in the orifice plate (14), wherein one of the at least two air inlet openings (22, 24, 26, 28) is additionally formed as a light opening (28) which also allows light to pass from the inner combustion region (16) to the photosensitive sensor (20) that is arranged in the outer region (18), wherein the at least two air inlet openings (22, 24, 26, 28) are being shaped such that the same combustion air quantities flow into the internal combustion region (16) per unit time, respectively, and wherein the orifice plate (14) is transparent and/or the light opening (28) has a shape different from the air inlet openings (22, 24, 26) that are not formed as light opening such that an illumination area defined by the light opening (28) is larger than a reference illumination area defined by one of the at least two air inlet openings (22, 24, 26) that are not formed as light opening (28).
