Advancements in LED brightness have opened new applications in the field of exterior lighting. The properties of LEDs introduce new requirements in the areas of mounting and lamp-assembly design. Designs must take into account all interacting factors that can impact system performance, such as color, peak candela, off-axis light distributions and thermal management. In addition, designers want to contour the RCL (Rear Combination Light) around the corner in the X- as well as the Y-axis of the car to realize different 3-D shapes. The use of SMT High Flux LED is a new innovative submount technology that fulfils design freedom and easy of assembly into lamp housings. An additional advantage is low thermal resistance to drive the LED with the highest possible current allowing high optical efficiency. The advantages of this concept will be described in general, including production flow. The mentioned solution based on so called 'submodules' that are sufficiently arranged, can realize all wishes of the designer while fulfilling production and technical efforts. In addition, the production flow will be described. Afterwards possible applications for RCL and CHMSL will be shown.
