Description
与散热器一体的大功率 LED照明光源单元 技术领域 High-power LED illumination source unit integrated with heat sink
本发明涉及 LED照明灯具的光源结构， 特别涉及一种可任意组合成 不同规格 LED灯具光源的、 与散热器一体的大功率 LED照明光源单元。 背景技术 The invention relates to a light source structure of an LED lighting fixture, in particular to a high-power LED illumination light source unit which can be arbitrarily combined into a light source of different specifications and is integrated with a heat sink. Background technique
在 LED未进入照明领域以前， 人们根据各种发光原理研制了各种规 格的传统光源， 如不同功率的白炽灯泡、 荧光灯管、 节能灯泡或钠灯等。 这些光源产品的特点是非组合式的， 即无论是 3W节能灯， 还是 1000W 的 "小太阳"， 都是一个独立发光体， 它并不是由多个低瓦数的独立发光 体组合而成的。 Before the LEDs entered the field of illumination, various conventional light sources, such as incandescent bulbs, fluorescent tubes, energy-saving bulbs or sodium lamps, were developed according to various illumination principles. These light source products are characterized by a non-combined type, that is, whether it is a 3W energy-saving lamp or a 1000W "small sun", it is a stand-alone illuminator, which is not composed of multiple low wattage independent illuminators.
但自 LED进入照明领域后，上述照明光源结构出现了变异。由于 LED 目前的发光效率偏低， 往往需要多个 LED组合在一起才能达到传统照明 所要求的最低亮度。 所以用 7个大功率 LED组合为台灯灯具光源， 用 48 个大功率 LED组合为隧道照明灯具光源是很普通的应用实例。 在此类灯 具中往往将这 7个或 48个大功率 LED做在一块基板上，进行悍接连接固 定并作为整体的灯具光源。很显然，这种光源结构与前述传统光源结构明 显不同。 但这种用多个大功率 LED直接悍接组合成整体光源的做法存在 十分明显的弊端： 不仅更换 LED很困难， 而且增加了灯具光源部分生产 和维修的复杂程度，造成生产和维修的低效率高成本。特别从散热角度考 虑，现有方法只能通过灯具另带的散热器件或灯具外壳进行散热， 散热效 率难以提高， 影响照明用 LED的使用寿命。 However, since the LED entered the field of illumination, the structure of the above illumination source has changed. Due to the current low luminous efficiency of LEDs, multiple LEDs are often required to combine to achieve the minimum brightness required for conventional illumination. Therefore, it is a common application example to use 7 high-power LEDs as the light source for table lamps. It is a common application example to use 48 high-power LEDs as the source of tunnel lighting. In such lamps, these 7 or 48 high-power LEDs are often placed on a single substrate to be spliced and fixed as a luminaire source. It is apparent that this light source structure is significantly different from the conventional light source structure described above. However, the practice of directly combining multiple high-power LEDs into an integrated light source has obvious drawbacks: not only is it difficult to replace the LED, but also increases the complexity of the production and maintenance of the light source part of the lamp, resulting in inefficiency in production and maintenance. High cost. In particular, from the perspective of heat dissipation, the existing method can only dissipate heat through the heat sink member or the lamp housing of the lamp, and the heat dissipation efficiency is difficult to increase, which affects the service life of the LED for illumination.
中国专利申请号 2004100519359公幵了 "一种 LED组合灯具" ， 其 将光源部分包括二个以上的发光模块组成， 通过 LED光源模块以多种形 式组合成灯具。 中国专利申请号为 2007200035576的 "一种 LED片材及 其组成的 LED灯具灯芯"专利， 用多个 LED安装在长方形印刷线路板的 LED.片材， 可任意组装成任意的截面为多边形的 LED灯芯。 这两个专利 将上述用多个 LED直接焊接组合成整体光源的做法作了一定改进， 把灯 具的整体光源通过较小的发光模块或 LED片材组合而成， 因此都具有简
化生产工艺、降低 LED灯具生产和维护成本的益处。但由于光源模块（或 者 LED片材）仍然由多个 LED直接焊接组合而成， 因此并没有从根本上 摆脱上述弊端，只是程度有所减轻而已。而且这两个专利都没有针对自身 主张的改进方案明确提出相应的 LED散热方案， 因此并不是理想的光源 结构。 发明内容 Chinese Patent Application No. 2004100519359 discloses "an LED combination luminaire" which comprises a light source part comprising two or more illuminating modules, which are combined into a luminaire in various forms by an LED light source module. Chinese Patent Application No. 2007200035576 "A kind of LED sheet and its composed LED lamp wick" patent, LEDs mounted on rectangular printed circuit boards with multiple LEDs, can be arbitrarily assembled into any polygonal LED Wick. These two patents have improved the above-mentioned direct welding of multiple LEDs into an integrated light source. The overall light source of the luminaire is combined by a small light-emitting module or LED sheet, so they are all simple. The production process and the benefits of reducing the production and maintenance costs of LED lamps. However, since the light source module (or LED sheet) is still directly welded and assembled by a plurality of LEDs, the above drawbacks are not fundamentally eliminated, but the degree is reduced. Moreover, neither of these patents explicitly proposes a corresponding LED heat dissipation scheme for the improvement scheme advocated by itself, and thus is not an ideal light source structure. Summary of the invention
为彻底改变用多个大功率 LED直接焊接组合成整体光源的做法， 本 发明的目的在于提供一种改进的光源结构， 可以将每个大功率 LED连同 与之一体化的散热器做成一个独立的光源单元，通过与匹配灯具接口可自 由拆装的活动连接方式， 这样的 LED光源单元即可任意组成所需要的光 源模块或灯具的整体光源。 In order to completely change the practice of directly welding a plurality of high-power LEDs into an integrated light source, the object of the present invention is to provide an improved light source structure, which can make each high-power LED together with the heat sink integrated therewith. The light source unit can be freely assembled and connected with the matching lamp, and the LED light source unit can arbitrarily constitute the required light source module or the overall light source of the lamp.

本发明的有益效果是： The beneficial effects of the invention are:
1 ) 使大功率 LED散热更加高效： 由于大功率 LED光源单元已和散 热器结为一体， 每个 LED工作时产生的大部分热量不仅随时通过自身的 散热器以热传导方式扩散，而且由于在散热器主体上靠近 LED的安装处， 沿散热器的轴线方向开有若干两端贯通的通孔，从而形成自对流散热， 因 此不易产生热量积累， 散热效果更加显著； 如果需要， 配套使用的灯具还 可设置专门的散热结构，其余部分的热量可由灯具提供的二次散热结构继 续散热， 实现两次散热效果， 因此散热效率提高， 对延长照明 LED的使 用寿命十分有益。 1) Make high-power LED heat dissipation more efficient: Since the high-power LED light source unit is integrated with the heat sink, most of the heat generated by each LED is not only diffused by heat conduction through its own heat sink, but also due to heat dissipation. The main body of the device is close to the mounting portion of the LED, and a plurality of through holes are formed in the axial direction of the heat sink to form self-convex heat dissipation, so that heat accumulation is less likely to occur, and the heat dissipation effect is more remarkable; if necessary, the used lamps are also used. A special heat dissipation structure can be set, and the rest of the heat can be cooled by the secondary heat dissipation structure provided by the lamp, thereby achieving two heat dissipation effects, so that the heat dissipation efficiency is improved, which is very beneficial for extending the service life of the illumination LED.
2 )本发明与散热器一体的大功率 LED照明光源单元可以小到只含一 个大功率 LED, 或者仅含为数不多的大功率 LED, 使 LED光源部件彻底 实现模块化， LED 光源部件可脱离灯具单独制作， 从而便于灯具光源的 规模化生产。 2) The high-power LED illumination light source unit integrated with the heat sink of the invention can be as small as one high-power LED, or only a few high-power LEDs, so that the LED light source components can be completely modularized, and the LED light source components can be separated. The lamps are made separately, which facilitates the large-scale production of the lamp source.
3 )方便灯具光源的安装和维修，哪只 LED光源单元损坏就更换哪只， 不会连累其它未损坏的 LED光源单元， 从而节省成本。 附图说明 3) It is convenient to install and repair the light source of the lamp. Which LED light source unit is damaged and which one is replaced, it will not be connected with other undamaged LED light source unit, thus saving cost. DRAWINGS
