1. An LED module for a blinder comprising several LEDs of the color warm white, one LED or several LEDs of the color red, and one LED or several LEDs of the color amber, and a control,
wherein the control is adapted to control the LEDs (30) of the colors amber, red and warm white, when the blinder is switched off such that the color decay behavior of a halogen illuminant based blinder is mimicked, the control of the LEDs of the color warm white being such that the emitted power of the LEDs of the color warm white decreases substantially exponentially, the control of the LEDs of the color amber being such that the emitted power of the LEDs of the color amber initially increases with starting decrease of the LEDs of the color warm white, until a maximum decay power of the LEDs of the color amber is reached, and subsequently decreases substantially exponentially, and the control of the LEDs of the color red being such that the emitted power of the LEDs of the color red is substantially zero until the maximum decay power of the LEDs of the color amber is reached, subsequently increases until a maximum decay power of the LEDs of the color red is reached, and subsequently decreases substantially exponentially.
