【技术领域】本发明涉及LED照明技术领域，更确切地说，涉及一种LED照明装置。 [Technical Field] The present invention is an LED lighting device relates to the field of LED lighting technology, and more particularly, relates. 【背景技术】随着LED技术的发展与成熟，LED的性能指标日益大幅度提高，目前白光LED的光效已经达到甚至超过普通白炽灯的光效水平，光通量也在大幅度增加，使LED在照明领域得到了广泛的应用。 BACKGROUND With the development of LED technology and mature, LED performance indicators increasingly greatly improved, the current white LED light efficiency has been achieved and even exceeded the level of an ordinary incandescent light efficiency, luminous flux is also a substantial increase in the LED lighting has been widely used. LED与一般光伏电源配用的节能照明灯具相比具有寿命长、发热低、不易损坏、功耗小及更加节能的突出优点，人们把它誉为21世纪替代荧光灯和白炽灯的第四代照明光源。 Energy-saving lighting LED equipped with general photovoltaic power compared to having long life, low heat generation, not easily damaged, and highlight the advantages of low power consumption more energy efficient, it hailed as the 21st century people replace incandescent and fluorescent lighting fourth generation light source. 目前的LED照明装置，通常是把多颗发光二极管按规定的方式安装在铝基板上形成发光二极管发光模组，通过铝基板散热。 Current LED lighting device, usually the predetermined multi-segment LED mounted on the aluminum substrate formed light emitting diode module, the heat dissipation through the aluminum plate. 为了达到散热要求，往往需要增加铝基板的厚度，这样一方面增加了整个照明灯具的重量，不方便使用，另一方也势必增加了制造成本，对于大功率发光二极管照明装置来说， 这种缺陷显得尤其明显。 To achieve the cooling requirements are often necessary to increase the thickness of the aluminum substrate, so that on the one hand increases the weight of the whole lighting, difficult to use, but also the other is bound to increase the manufacturing cost, for high-power LED illumination apparatus, this defect It is particularly evident. 比如， 一个通过铝基板散热的120瓦左右的大功率发光二极管路灯，其重量大概在9公斤左右，其中一大部分是为了达到散热的需要而增加铝基板的厚度以及散热片的高度而产生的，这一方面大大的增加了整个路灯的重量，使得安装拆卸均不方便，而且增加了材料成本；另一方面对于过高的散热片，尤其是一体成型的情况下，对模具的要求也比较高， 而且产品的成品率会有所降低，这也在一定程度上增加了制造成本；而且即使如此，其整体上也很难到达理想的散热效果。 For example, by generating a power LED street lamp of approximately 120 watts of cooling aluminum plate, which is probably about 9 kg weight, most of which is to achieve a heat needed to increase the height of the fin and the thickness of the aluminum plate this aspect greatly increases the weight of the lights, so that it is not convenient installation and removal, but also increases the cost of materials; hand for excessive heat sink, especially in the case of integrally molded, the mold requirements are relatively high, and the product yield will be reduced, increasing manufacturing costs which to some extent; but even so, on the whole it is difficult to reach the desired cooling effect. 【发明内容】本发明解决的技术问题是克服现有技术存在的缺陷，提供一种重量轻、 成本低且散热效果很好的LED照明装置。 SUMMARY OF THE INVENTION technical problem solved by the present invention is to overcome the drawbacks of the prior art, to provide a light weight, low cost and good heat
