1240 may be a cone shaped reflector which may exhibit total reflection or which allows the majority of light from the light source to be reflected but a small part to pass through in the original light direction thus it can be understood that the light emitted from the led source 110 arrives first at the outer surface of the cone shaped reflector 1240 the slope angle of the outer surface of the cone is designed in such a manner that the reflected light coming from the cone can be incident substantially laterally on the reflecting interface of the 1 st optical component 1220 in the embodiment shown by fig4 a fig4 c the oblique angle of incidence of each reflective interface in relation to the light source is set to 45 u00b0 and the slope angle of the outer surface of the cone is 45 u00b0 as well it has to be noted that the substantially perpendicular configuration enables energy to be used maximally without limiting other variations where the relative position of the transitional component and the 1 st optical component is provided with other angles since each optical component is arranged obliquely in relation to the led source the light emitted from the led source can be directed through the cone shaped reflector 1240 to the reflecting interface 1220 r of the 1 st optical component 1220 assuming there was a plane parallel to the front and back plate of the light box where the led source is located on all optical.
