    • An illumination device comprising a carrier (1), a LED module (2) arranged on the carrier, the LED module comprising a plurality of LEDs (3), and a ring-shaped element (6) surrounding the LED module (2) and in contact with the carrier (1), sides of the ring-shaped element (6) facing the LEDs (3) being reflective. The ring-shaped element (6) has a first proximal portion (7) arranged closest to the carrier and defining an opening to surround the LED module, and a second, distal portion (8) arranged outside the proximal portion withrespect to the carrier and defining an exit aperture of the illumination device. The exit aperture is smaller than the opening in the proximal portion, so that the distal portion covers a portion (9) of the opening in the proximal portion. The inner edge of the secondportion thus forms an overhang along portions of the ring-shaped element, and along these portions covers an area immediately inside the proximal portion. In this shielded area parts of a relatively large LED module can be housed and be protected by the distalportion.
    • 一种照明装置,包括载体(1),布置在载体上的LED模块(2),所述LED模块包括多个LED(3)和围绕所述LED模块(2)的环形元件(6)和 与载体(1)接触,面向LED(3)的环形元件(6)的侧面是反射性的。 所述环形元件(6)具有最靠近所述载体布置并限定围绕所述LED模块的开口的第一近端部分(7)和布置在所述近端部分外侧的第二远端部分(8) 限定照明装置的出口孔。 出口孔小于近端部分中的开口,使得远侧部分覆盖近端部分中的开口的部分(9)。 因此,第二部分的内边缘沿着环形元件的部分形成突出部分,并且沿着这些部分覆盖近侧部分内部的区域。 在该屏蔽区域中,相对较大的LED模块的部件可被容纳并被远端部分保护。
