Embodiment Construction

[0061]Below, the substantive features and advantages of the present invention will be further described in conjunction with examples, but the present invention is not limited to the listed examples.

[0062] see Figure 1~3 As shown, the dual-objective comprehensive optimization design method for the structural parameters of the LED radiator includes the following steps:

[0063] (1) Select two single objective functions F for comprehensive optimization 1 and F 2

[0064] Before optimizing the design, it is first necessary to select two single design objectives for comprehensive optimization. One of the design objectives is to improve the heat dissipation performance, which is generally expressed as a single objective function F such as the junction temperature of the LED chip, the temperature of key nodes, or the thermal resistance of the heat sink. 1 Numerical reduction, another design goal is usually a single objective function F such as the weight, volume or manufacturi...

Abstract

The invention discloses a double-objective comprehensive optimization design method for LED radiator structure parameters. According to the method, a continuous function relation between a comprehensive optimization target and the structure parameters to be optimized is accurately built through a response surface method, an orthogonal testing method and a genetic algorithm are reasonably combined to use, global optimization can be completed in a solution space of a comprehensive optimization target function of the structure parameters of a radiator in complex appearance, and a Pareto optimal solution achieving comprehensive optimization of double objectives containing improvement of LED cooling performance can be obtained, so that the optimal combination of various structure parameter design values is quickly determined according to actual requirements of the design target of the radiator, cooling efficiency of the radiator is effectively improved, the research and development period is greatly shortened, and product cost in the links of design, manufacturing, application and the like is reduced.

Description

technical field [0001] The invention belongs to the technical field of encapsulation and heat dissipation of electronic equipment, and in particular relates to a design method for optimizing structural parameters of an LED heat sink by combining an orthogonal test method and a genetic algorithm to simultaneously achieve the comprehensive optimization of two design objectives. Background technique [0002] High-power LED has a series of significant performance advantages such as low power consumption, long life, small size, and quick response. With its wide application in many lighting fields, LED lamps have become a promising alternative to incandescent lamps, fluorescent lamps and halogen lamps. New lighting products of traditional light sources such as lamps. However, since LEDs are heat-sensitive devices, if there is no effective heat dissipation measures to accumulate heat on the chip, it will directly lead to a rapid rise in junction temperature, which will not only cau...
