High power LED lighting industry's technology roadmap
Existing led 1w lighting cooling technology exists to thermal resistance, low heat capacity, we are trying to chip a heat integration (two-story structure) model "to address the low luminous efficiency of high power LED lighting, the light fades serious cost Advanced series of questions.
1.technology roadmap
Chip a heat integration (two-story structure) mode, not only to go in addition to the structure of the aluminum plate, but also multiple chips on directly placed on a heat sink to form a multi-chip module single light source, was prepared by the Integrated led power 50w , light source for the single, showing the surface light source or cluster light.
2. The key technology
How to enhance the ability to conduct heat to the chip, reducing the thermal resistance of the interfacial layer, related to the structural model of thermal management systems, fluid mechanics and super-thermal conductivity materials engineering applications; how to effectively control the thermal matrix heat reserves, planning convection heat path, the establishment of efficient natural convection cooling system, proceed from the lamp structure design.
3. The technical program
By changing the package structure of led 10w light source, the structure of cooling and lighting structure model to reduce the thermal resistance layer; super-thermal conductivity materials, to increase the thermal conductivity of the chip heat source; to optimize the thermal management system based on "chip a heat integrated two-story structure, increase air flow, the formation of natural convection.
4. The design concept
Prepared to take a modular High Power LED 50W lamps. Package of light, heat, shape and structure as a whole module between the module independent of each other, any module can be replaced individually when a partial failure, simply replace the faulty module without having to replacement of other modules or the overall change will be able to continue working normally. All modules part of the lamp can hand disassembly, convenient, fast, low-cost maintenance.
5.Design Points
System module, in addition to meet the heat lamp replacement requirements must be met for the optical (optical efficiency) demand for led power 10w lighting, and modeling (market) demand.
