Luminous body with LED dies and production thereof
View Patent ↗A luminous body comprises a transparent plastic moulding with indentations, and LED DIEs disposed within the indentations. One side of each LED DIE lies approximately flush with an upper side of the moulding, and each LED DIE is connected to an electricity supply via electrical conductors disposed on the moulding. A method for producing such a luminous body is also disclosed.
1. A luminous body comprising a transparent plastic moulding and LED DIEs, wherein the moulding includes a plurality of indentations, with one of the LED DIEs being disposed in each of the indentations such that one side of each LED DIE lies substantially flush with an upper side of the moulding, and each LED DIE is connected to an electricity supply via two electrical conductors disposed on the moulding, wherein the two electrical conductors contacting the upper side of the moulding so as not to cover the indentations, and two poles directly connecting the one side of each of the LED DIEs to the two electrical conductors, wherein the luminous body further comprises a plastic film disposed on the plastic moulding over an open side of the indentations, wherein the plastic film is configured to permit the LED DIEs to radiate on the open side of the indentations.
2. The luminous body according to claim 1 , wherein the LED DIEs are fixed in the indentations by a casting compound.
3. The luminous body according to claim 1 , wherein the electrical conductors include a first conductor track disposed on an opposite side of the moulding from a second conductor track.
4. The luminous body according to claim 1 , wherein the plastic film is disposed as a protective layer over the electrical conductors.
5. A luminous body comprising a transparent plastic moulding and LED DIEs, wherein the moulding includes a plurality of indentations, with one of the LED DIEs being disposed in each of the indentations such that one side of each LED DIE lies substantially flush with an upper side of the moulding, and each LED DIE is connected to an electricity supply via two electrical conductors disposed on the moulding, wherein the two electrical conductors contacting the upper side of the moulding so as not to cover the indentations, and two poles directly connecting the one side of each of the LED DIEs to the two electrical conductors, wherein the luminous body further comprises a plastic film disposed on the plastic moulding over an open side of the indentations and wherein the plastic film is configured to direct light from the LED DIEs through a bottom of the indentations.
6. The luminous body according to claim 1 , wherein the LED DIEs are fixed in the indentations by a casting compound.
7. The luminous body according to claim 1 , wherein the electrical conductors are disposed on a side of the moulding including an open side of the indentations.
8. The luminous body according to claim 5 , wherein the electrical conductors include a first conductor track disposed on an opposite side of the moulding from a second conductor track.
9. The luminous body according to claim 5 , wherein the plastic film is disposed as a protective layer over the electrical conductors.
10. The luminous body according to claim 5 , wherein the plastic film includes a reflective layer.
11. The luminous body according to claim 1 , further comprising a reflective layer disposed on the plastic moulding on an open side of the indentations.
