Lamp with rigid LED strip - Design and thermal management
Investigations are connected with design and application of thermally and cost effective rigid LED strips. Standard FR 4 PCB is used for making rigid strip and LEDs are soldered on it. Special copper pins soldered underneath LEDs contribute to low thermal resistance between LEDs and heat sink - like when MCPCBs are used. Application of this type low cost rigid LED strips allows decreasing operations (and expenses) connected with assembling of LEDs onto a heat sink several times. A lamp for interior lighting is designed on the base of this type LED strips. Thermal management calculations are made and proper heat sink is chosen. Thermal loading of LEDs is experimentally tested at various ambient conditions (air temperatures from 20°C to 45°C) and different current values through LEDs - up to 600 mA. Infrared thermography is used for evaluation of temperature distribution on LEDs and heat sink. Thermal management investigations show very good qualities of developed LED strips.
Multifunctional LED lamp thermal management
Investigations in this work are connected with design of energy effective multifunctional lamp for interior lighting. A mechanical construction of a desk lamp is used. LEDs are chosen as light sources. Characteristics of LEDs allow creating lightweight construction which can serve as: desk lamp (light flux about 600 ÷ 700 lm); night light for baby room (light flux about 100 ÷ 200 lm) and lamp for general lighting of a living room (light flux about 1000 ÷ 1200 lm). Choice of proper LEDs is made. Investigations in thermal camera for optimization of thermal management of LEDs are aided by application of infrared camera. Proper choice of heat sink ensures low operation temperature regimes for LEDs and long life of the light equipment.
