Evgeni Arkad Evich Patent

The invention provides an elongated luminescent body () comprising an elongated support () and a coating layer (), wherein the elongated luminescent body () further comprises a body axis (BA), and a length parameter P of a body dimension perpendicular to the body axis (BA), wherein the length parameter P is selected from height (H), width (W) and diameter (D), wherein: &#x2014;the elongated support () comprises a support material (), a support material index of refraction n1, wherein the support material index of refraction n1 is at least 1.4, a support surface (), and a support length (L); &#x2014;the coating layer () is configured on at least part of the support surface () over at least part of the support length (L), wherein the coating layer () comprises a coating layer material (), a coating layer index of refraction n2, wherein coating layer index of refraction n2 is at least 1.4, and a coating layer thickness (d), wherein the coating layer material () has a composition different from the support material (), wherein the coating layer material () comprises a luminescent material () configured to absorb one or more of UV radiation and visible light, and to convert into luminescent material light () having one or more wavelengths in one or more of the visible and the infrared; and &#x2014;the support material () is transmissive for the luminescent material light (), and (i) &#x2212;0.2&#x2264;n1&#x2212;n2&#x2264;0.2 and (ii) d/P&#x2264;0.25 apply.

Light generating system comprising an elongated luminescent body

The invention provides a lighting device () lighting device () comprising: (I) a first light source () configured to provide first light source light (); (II) a luminescent material () configured to convert at least part of the first light source light () into luminescent material light (); (III) a beam shaping optical element () having a light entrance side () and a light exit side (), and a wall () bridging a distance between the light entrance side () and the light exit side (), wherein at least part of the wall () is reflective for the luminescent material light (), wherein the beam shaping optical element () is configured to receive at least part of the luminescent material light () at the light entrance side () and to provide beam shaped luminescent material light () at the light exit side (); (IV) an elongated light transmissive body () having a first face () and a second face () defining a length (L) of the light transmissive body (), and having one or more side faces () bridging the length (L) between the first face () and the second face (), the light transmissive body () comprising a radiation input face () and a first radiation exit window (), wherein the first face () comprises the radiation input face () and wherein the second face () comprises the first radiation exit window (), wherein the radiation input face () is configured to receive at least part of the beam shaped light luminescent material light (); (V) a second light source () configured to provide second light source light (); wherein the elongated light transmissive body () is configured to receive at least part of the second light source light () via one or more of (i) incoupling of the second light source light () via the wall () of the beam shaping optical element (), (ii) incoupling of the second light source light () via part of the first face () of the elongated light transmissive body (), and (iii) incoupling of the second light source light () via part of the of the one or more side faces () of the elongated light transmissive body ().
