Design of heat management model of 6,000 lumen LED worklamp using integrated SEPIC drivers

This paper presents the design of heat transfer on integrated heatsink for 6000 lm worklamp. The integrated driver using DC-DC Single-ended primary-inductor converter (SEPIC) converts 9 V - 36 V to 15 V 2A for 2 sets attaches to the heatsink as the housing of the lamp. Each set of drivers consumes 30 watt for 3000 lm fitted with a very compact sizing and complied with IP 67 requirements. The high performance SEPIC converter is proposed and achieved at 83.79% concerned with the primary source of the heat management train. The proposed design model shows a heat management model to maintain a long run operating temperature at 60 °C ambient temperature. The EMC issue based on the radiated emission was proved to comply with international standards. This work can be applied in building, field-yard, security area and automotive for both local and worldwide market.
