Abstract:
A lighting device with front carrier, rear carrier and plurality of light-emitting diode chips, which when in operation emits light and releases waste heat, wherein rear carrier is covered at least in selected locations by front carrier, light-emitting diode chips are arranged between rear carrier and front carrier to form array, light-emitting diodes are contacted electrically by rear and/or front carrier and immobilized mechanically by rear carrier and front carrier, front carrier is coupled thermally conductively to light-emitting diode chips and includes light outcoupling face remote from light-emitting diode chips, which light outcoupling face releases some of waste heat released by light-emitting diode chips into surrounding environment, each light-emitting diode chip is actuated with electrical nominal power of 100 mW or less when lighting device is in operation and has light yield of 100 lm/W or more.
