Description

具有模块化光源结构的 LED照明灯  LED lighting with modular light source structure
技术领域  Technical field
本发明涉及一种 LED照明灯,特别是提供一种以大功率 LED作为光 源并具有模块化光源结构的 LED照明灯。 背景技术  The present invention relates to an LED illumination lamp, and more particularly to an LED illumination lamp having a high power LED as a light source and having a modular light source structure. Background technique
由于照明用 LED是靠直流驱动点亮的, 所以必须通过将交流变直流 的驱动电源才能接入市电。 如果驱动电源与 LED光源结合为一个部件, 则 LED照明灯和使用普通光源 (白炽灯日光灯等) 的照明灯无异, 这种 情况不在本发明涉足之列; 本发明专门针对内装驱动电源的 LED照明灯 具进行改进。  Since the LED for illumination is illuminated by a DC drive, it must be connected to the mains by driving the AC to DC drive. If the driving power source and the LED light source are combined into one component, the LED lighting lamp is the same as the lighting lamp using the ordinary light source (incandescent fluorescent lamp, etc.), which is not involved in the present invention; the present invention is specifically directed to the LED of the built-in driving power source. Lighting fixtures are being improved.
虽然经过不断努力, 已开发出瓦级以上的大功率 LED, 但对照明需 求而言, 目前照明用 LED的功率仍旧偏小, 往往需要若干个 LED组成一 个整体光源, 由多个大功率 LED按一定间隔直接焊接固定在一块线路基 板上实现相互电路连通, 并将其作为一个独立部件通过简单紧固方法(如 螺丝拧紧等)装在内含驱动电源的灯具内,整体光源基板的正负极再与灯 具驱动电源输出端进行电路连接。这样做的缺陷非常明显,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。  Although continuous efforts have been made to develop high-power LEDs above the watt level, for lighting demand, the power of LEDs for lighting is still too small, and it is often necessary to form several LEDs as one overall light source, which is pressed by multiple high-power LEDs. Directly soldered and fixed on a circuit board at a certain interval to achieve mutual circuit communication, and as a separate component, it is installed in the lamp containing the driving power supply by a simple fastening method (such as screw tightening), and the positive and negative electrodes of the overall light source substrate Then, the circuit is connected with the output end of the lamp driving power supply. The drawbacks of this are obvious. Not only is it difficult to replace the LEDs, but it also increases the complexity of the production and maintenance of the light source part of the luminaire, resulting in low efficiency and high cost of production and maintenance. Especially 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 be improved, which affects the service life of the LED for illumination.
中国实用新型专利 ZL200620011390.3公开了一种 LED灯, 由灯头、 灯壳、 LED灯、 LED固定板、 电子元件、 电子元件固定板组成, 由 LED 灯及 LED固定板组成的 LED组合件与由电子元件及电子元件固定板组成 的电子电路组合件, 固定为一体, 嵌入并卡合于灯头内。 这个专利较上述 LED 直接焊接于线路板的方法要进步一些, 但是, 其结构形式仍决定了 该产品无法满足生产和维修的需要。 发明内容 W 本发明的目的是提供一种 LED 照明灯, 特别是提供一种以大功率 LED作为光源并具有模块化光源结构的 LED照明灯, 是专门针对一种特 定的 LED光源单元设计并提供配套使用,该特定的 LED光源单元已由本 申请人同时递交申请题为 "与散热器一体的大功率 LED照明光源单元" 的另一发明专利。 本发明具有模块化光源结构的 LED照明灯与所指特定 的 LED光源单元配合使用, 可有效解决 LED光源安装困难的问题, 弥补 了现有技术无法方便拆卸更换 LED的不足和缺陷, 满足生产和生活的需 要。 The Chinese utility model patent ZL200620011390.3 discloses an LED lamp, which is composed of a lamp cap, a lamp shell, an LED lamp, an LED fixing plate, an electronic component, an electronic component fixing plate, and an LED assembly composed of an LED lamp and an LED fixing plate. The electronic circuit assembly composed of the electronic component and the electronic component fixing plate is fixedly integrated and embedded and engaged in the lamp cap. This patent is a bit more advanced than the method of directly soldering the LED to the circuit board. However, its structural form still determines that the product cannot meet the needs of production and maintenance. Summary of the invention An object of the present invention is to provide an LED illuminating lamp, in particular to provide an LED illuminating lamp with a high-power LED as a light source and a modular light source structure, which is specifically designed and provided for a specific LED light source unit.
