Led circuit board and light emitting module

A light emitting module comprising:

• a reflector panel having an inner surface side subdivided into a two-dimensional array of surface sections, such as surface sections having a square or hexagonal geometry, generally a geometry that allows combination to cover a continuous surface, wherein each surface section comprises a concave reflecting surface area and a thermal contact area outside of the concave reflecting surface area;
• a transparent circuit board mounted to the reflector panel with a first surface side facing the inner surface side of the reflector panel;
• LEDs distributed in a two-dimensional array on the first surface side of the transparent circuit board such that each LED is associated with one of the concave reflecting surface areas;
• heat conductors that respectively thermally connect one of the LEDs with one of the thermal contact areas;
• wherein in particular, during operation of the light emitting module,
• light emitted from one of the LEDs is reflected by the associated concave reflecting surface area to pass through the transparent circuit board, and
• heat generated by the LEDs is spread via the heat conductors and the thermal contact areas.

An LED-based optical system/light emitting module comprising:

• a support board with a plurality of mounting positions, wherein
• the mounting positions are distributed in a regular two-dimensional pattern on a first surface side of the support board, and
• the support board is transparent with respect to visible light at least within a plurality of transmission areas (light transmitting regions), each transmission area extending around one of the plurality of mounting positions, and
• wherein the regular two-dimensional pattern is defined by equal distances between neighboring mounting positions in a respective direction;
• a plurality of light sources mounted to the support board at the plurality of mounting positions, wherein each light source includes at least one LED,
• a reflector panel having a three-dimensionally shaped surface and mounted to the support board, wherein
• the three-dimensionally shaped surface faces the first surface side of the support board and includes a plurality of connecting surface sections (thermal contact areas) and a plurality of reflective surface sections (concave reflecting surface areas),
• the plurality of connecting surface sections extends within a connecting plane and is in contact with the first surface side of the support board, and
• each reflective surface section faces an associated transmission area of the support board;
• and
• a plurality of conducting tracks (heat conductors) extending on the first surface side and configured for thermal dissipation of heat from the light source and/or for power supply of the light source, wherein at least one of the plurality of conducting tracks extends from one of the plurality of mounting positions to at least one of the plurality of connecting surface sections.
