【摘要】：随着LED产业技术的不断发展,LED作为一种发光元件得到了越来越广泛的应用。最近几年,LED照明的发展突飞猛进,大功率LED照明作为发展最快最先运用于照明领域的照明技术也日新月异。大功率LED照明灯具经过一段时间的研发,已经在城市道路及工业照明上得到较为广泛的运用,为解决长期以来大功率灯具的散热与标准化问题,灯具模块化孕育而生。所谓的模块化是指将一个灯具里面由多个具有独立的散热、防水及配光功能的LED光源模组组成在一起,形成类似于传统灯具的光源。将这些核心的光源部件和电源驱动器以及外壳组合起来就成为一个灯具。这样有助于解决散热及灯具的标准化生产问题,是目前最新的大功率LED灯具设计概念。本文运用模组化的思想,对大功率LED灯珠组成的灯具的核心部件：光源模组进行结构、散热、电路、光路进行了研究。采用CREE X-Lamp系列的XPG大功率LED灯珠进行产品设计,在芯片散热上进行新型结构散热器的设计,以及设计新型灯具结构以增强防水性能,光学上使用一体化透镜的设计方法增加透镜的透光率,并使用Tracepro进行光线追迹设计透镜结构与模拟。对所设计的实际成型的LED光源模组进行了严格的光、电、热检测。根据检测的产品性能指标反算出LED的结温,并且利用dialux软件进行照明设计并用光源模组组合的灯具进行照明场景模拟,以验证其实际应用上的优势。最后结合实际应用的案例说明了该LED光源模组的应用前景。
[Abstract]:With the development of LED industry, LED as a light emitting element is widely used. In recent years, the rapid development of LED lighting, high power LED lighting as the fastest-growing lighting technology was first used in the lighting field also change rapidly. High power LED lighting development after a period of time, has been has been widely used in City Road and industrial lighting, to solve the long heat and standard high power lamps of lamps, modular born. The so-called modular refers to a lamp which is composed of a plurality of independent heat dissipation, waterproof and light distribution function of the LED light source module in together, the formation of light source is similar to the traditional lamps. The core of the light source unit and a power drive and shell combination has become a fixture. This helps to solve the heat and light Production standardization, is the latest high power LED lamp design concept. This paper uses modular idea, core components of high power LED lamp bulb: light source module structure, cooling circuit, optical path is studied. Using the XPG high power LED lamp CREE X-Lamp series of product design design of the new structure, the heat radiator in the chip, and design a new type of lamp structure to enhance the waterproof performance, the use of integrated design method of the optical lens increases the light transmittance of the lens, and the ray tracing design of lens structure and simulation using Tracepro. The LED light source module of the actual forming of the designed strictly light electricity, heat, temperature detection. According to the product performance of detection of anti LED to figure out, and lighting design and lighting light source modules in the lighting field by using Dialux software In order to verify the advantages of its practical application, the application prospect of the LED light source module is illustrated.
