1. A display device comprising:
- a support and luminous means arranged on said support, the luminous means comprises a surface mount light emitting diode (LED); and
a light distributor as a separate component that is provided above said luminous means with a direction of light emission away from said support and away from said luminous means, said light distributor comprising a three-dimensional light distributing body with a light entrance side facing towards said luminous means and a light exiting side facing away from said luminous means, wherein said light distributing body comprises a transparent material and said light entrance side is shaped to optimize a uniform light distribution from said luminous means to said light exiting side,wherein the light distributing body is provided above said surface mount LED,wherein said light entrance side comprises a double S shape in side section, with its highest point over a centre point of said luminous means or said light-emitting area thereof, andwherein a maximum height difference between a lowest point and said highest point of said light entrance side amounts to less than 0.2 mm.

Abstract
A display device comprises a support, on which there are arranged LED and a light distributing body above the luminous means with a direction of light emission away from the support and the LED. The light distributing body is a three-dimensional body with a light entrance side facing towards the LED and a light exiting side facing away from the LED. The light distributing body consists of transparent material and the light entrance side is shaped to optimise uniform light distribution from the LED to the light exit side, which may take the form of a diffuser.
