Definitions
- the invention relates to an LED lamp for illumination, in particular to an LED spotlight, an LED ceiling lamp, an LED ceiling lamp, an LED lamp tube, an LED bulb, an LED street lamp, an LED table lamp, an LED tunnel lamp and the like.
- LED light-emitting diodes Compared with traditional light sources, LED light-emitting diodes have no lead, mercury, no stroboscopic, energy saving, long service life, fast response, vibration resistance, easy maintenance, high brightness, low energy consumption, no ultraviolet radiation and environmental pollution. It has been widely used in electronic devices or lighting fixtures due to its high safety and many other advantages.
- the light decay of the LED source and its lifetime are directly related to its junction temperature.
- LED lights especially high-power LED light sources, concentrate heat when emitting light. If the heat generated by the LED chips does not dissipate in time, the junction temperature is very high and the lifetime is short. According to the Ares rule, for every 10 ° C decrease in temperature, the life expectancy is doubled. According to research, if the junction temperature can be controlled at 65 ° C, the lifetime of the LED light source can be as high as 100,000 hours. Since LEDs are electroluminescent devices, their heat cannot be dissipated by radiation. In the photoelectric conversion process, only 15-25% of the electrical energy is converted into light energy, and the remaining electrical energy is almost converted into thermal energy, which causes the temperature of the LED lamp to rise.
- the heat source area is high in heat, which is likely to cause the temperature of the device such as the LED chip to be too high. If a large amount of heat is not released in time, it will cause a series of problems: for example, it will accelerate the aging of LED chips and other devices, shorten the service life, and even lead to the burning of LED chips; red-shift the wavelength of blue LEDs, and the color of white LEDs. Degree and color temperature have an important influence. If the wavelength shifts too much, it will deviate from the absorption peak of the phosphor, which will cause the quantum efficiency of the phosphor to decrease and affect the light extraction efficiency.
- the temperature also has a great influence on the radiation characteristics of the phosphor, with the temperature rising.
- the quantum efficiency of the phosphor is reduced, and the wavelength of the radiation is also changed.
- the change of the wavelength of the phosphor radiation also causes the color temperature and chromaticity of the white LED to change, and the higher temperature accelerates the aging of the phosphor.
- the greater the power of the LED chip integrated packaged light source the farther the illumination distance is, and the better the illumination effect; but at the same time, the heat dissipation problem is more difficult to solve.
- the heat dissipation problem finally restricts the improvement of the power of the LED chip integrated packaged light source.

Radiation, through the external low temperature air heat exchange to reduce the temperature effect of the metal heat sink parts, to ensure the life of the LED light source.

- the die passes through the heat dissipation base as the first heat sink. Since the columnar heat sink base does not directly contact the air to dissipate heat, and has a certain solid metal length, heat can be dissipated to the air due to the long metal conduction heat dissipation distance. Moreover, the contact area of the heat dissipation base and the air is small, so the heat generated when the crystal grains emit light may have a heat accumulation effect.

Description
一种 LED灯 技术领域
本发明涉及一种用于照明的 LED灯, 特别是涉及一种 LED射灯、 LED吸顶灯、 LED吊 顶灯、 LED灯管、 LED灯泡、 LED路灯、 LED台灯、 LED隧道灯等。
背景技术
LED发光二极管较之传统光源具有不含铅、 汞, 无频闪, 节能环保、 使用寿命长、 响 应速度快、 耐震动、 易维护、 亮度高、 能耗低、 没有紫外辐射和环境污染、 使用安全性高 等诸多优点而被广泛地应用在电子装置或照明灯具上。
LED光源的光衰和其寿命直接与其结温有关。 LED灯, 特别是大功率的 LED光源, 发 光时热量集中, 如果 LED芯片产生的热量不及时散发出去, 结温就非常高, 寿命就短。 依 照阿雷斯法则, 温度每降低 10° C, 寿命就会延长两倍。 据研究表明, 结温假如能控制在 65 ° C, LED光源光衰至 70%的寿命就可高达 10万小时。 由于 LED属于电发光器件, 其热 量不能通过辐射方式散发出去。 其光电转换过程中只有 15— 25 %的电能转换成光能, 其 余的电能几乎都转换成热能, 使 LED灯具的温度升高。 而对于 LED晶片集成封装式光源来 说, 由于晶片比较集中, 发光源区热量高, 这样就很容易导致 LED芯片等器件温度过高。 大量的热量如果不能及时散发出去会引发一系列问题:例如,会加速 LED芯片等器件老化, 縮短使用寿命, 甚至会导致 LED芯片烧毁; 使蓝光 LED的波长发生红移, 并对白光 LED的 色度、 色温产生重要影响, 如果波长偏移过多, 偏离了荧光粉的吸收峰, 将导致荧光粉量 子效率降低, 影响出光效率; 温度对荧光粉的辐射特性也有很大影响, 随着温度上升, 荧 光粉量子效率降低, 辐射波长也会发生变化, 荧光粉辐射波长的改变也会引起白光 LED色 温、 色度的变化, 较高的温度还会加速荧光粉的老化。 通常, LED晶片集成封装式光源的 功率越大, 照射的距离也越远, 照射效果越好; 但与此同时, 散热问题越难解决。 散热问 题最终制约了 LED晶片集成封装式光源功率的提高, 目前在技术比较发达的美国单颗 LED 晶片集成封装式光源功率最大功率也只能达到 25W, LED散热技术已成为大功率 LED技术 发展的瓶颈。
现有的 LED光源的散热通常采用以下几种方式:其一,将 LED光源与金属散热部件(如 金属散热基板、 金属热沉) 、 散热片、 散热孔结合, 利用金属散热部件的热传导与热辐射 作用, 通过外界较低温度空气热交换达到降低金属散热部件温度效果, 确保 LED光源的寿 命。 这种散热方式, 由于现有的散热孔一般设置在散热基板的侧面, 并没用将 LED光源隔 开, LED光源产生的热量需先上升再通过散热孔散发出去, 外界的冷空气也需通过设置在 散热基板侧面的散热孔达到 LED光源。 这种散热方式, 由于散热基板朝向灯盖的一侧被密 封, 因此不能形成对流的气体散热通道, 散热孔仅水平方向布置, 不利于空气对流散热, 散热效果不好。 其二, 采用风扇强制对流方式散热, 利用风扇抽取灯壳外较低温度的空气 与灯壳内较高温度的空气进行热交换, 并经过灯壳外表面散热降低灯壳内空气温度, 从而 LED元件温度, 确保 LED光源的寿命。 风扇散热方式结构复杂, 成本高, 本身耗能, 更重 要的是风扇的寿命比芯片还短, 可靠性低, 需要经常性的维护和维修。 其三是热管和回路 热管散热等, 热管散热结构复杂, 成本高; 散热片散热, 因表面积有限, 效果同样不好。
申请号为 201020001106. 0的实用新型专利中, 公开了一种用于 LED晶片集成封装式 光源的散热装置, 包括实体的基座, 在基座内设有若干个用于空气对流的垂直贯通孔。 若 干个垂直贯通孔的中心线与基座的中心线平行。 若干个垂直贯通孔布置在多个同心圆筒 上, 并且位于相邻两个同心圆筒上的垂直贯通孔相互错开布置。 在该实用新型的用于 LED 晶片集成封装式光源的散热装置的基座 2下端面 21的凸圈 7内的区域安装上 LED晶片集 成封装式光源 1, 并在铜基板 5上安装能罩住 LED晶片集成封装式光源 1的灯具透镜 9, 就形成了一个灯具模块。将 3个这样的灯具模块安装到灯具壳体 6内,就组成了 LED灯具。 为了增加散热面积, 在上壳体 63上可以设置与其一体的若干散热鳍片 61。 上壳体 63上
设有若干个与基座 2内的垂直贯通孔相适应的通气孔 62。 该实用新型专利中, 虽然公开 了用与外界连通垂直贯通孔散热, 对散热有一定效果, 但还是存在以下缺点: 一是垂直贯 通孔只分布在 LED晶片集成封装式光源外, 每个 LED晶片集成封装式光源模块基座上的 LED芯片还是无散热孔隔开的密集排列, 密集排列的多个 LED芯片产生的热量还是无法通 过基座和基座上的垂直贯通孔迅速排出去, LED光源热量非常集中, 节点温度高, 荧光粉 更容易老化; 二是 LED芯片产生的热量需先传导到基座上, 再传导到壳体上, 由于热传导 增加了中间环节, 以及很厚的金属传热体对应的很长的传热路径, 热量会先把该传热路径 的固体先加热透, 就会先形成很顽固的热量聚集, 虽然接近空气的最外端散热处会温度低 些, 但中间的传热体因热量聚集而温度始终不易下降, 热量不易散去, 散热效果很差。 晶 粒通过散热基座作第一散热体, 由于柱状的散热基座不直接接触空气来散热, 而且其具有 一定的金属实心长度, 由于需要较长的金属传导散热距离才能将热散发于空气, 且散热基 座与空气的接触面积小, 因此晶粒发光时产生的热量会起到热聚集效应。
申请号为 200720121299. 1的实用新型专利中, 公开了一种 LED灯, 具有一灯体, 灯 体包括灯罩及灯杯,灯罩与灯杯相连接,且灯罩与外接插座相连接;灯罩内装有供电电路, 灯杯上设有与供电电路电性连接的 LED; 灯体上设有供外界冷风进入灯体内的入风口及供 LED灯内部产生的热量排出的散热孔; 其中, 灯杯为导热体, 其上设有一容置空间, 容置 空间内设有一与供电电路电性连接的散热风扇。 上述 LED灯在灯体内安装有散热风扇, 散 热风扇工作时, 可将 LED产生的热量通过灯体上的散热孔排出 LED灯内部。 该专利中, 由 于灯体上设有供外界冷风进入灯体内的入风口及供 LED灯内部产生的热量排出的散热孔 沿灯体的侧壁排列,入风口和出风口形成的散热通道是水平方向的,不利于空气对流散热, 所以该实用新型中增加了风扇来加速空气的对流散热。增加风扇散热, 虽然可提高散热效 果, 但风扇散热方式结构复杂, 成本高, 本身耗能, 更重要的是风扇的寿命比芯片还短, 可靠性低, 需要经常性的维护和维修。
申请号为 200910111308. 2的发明专利中, 公开了一种具有 LED光源模块的封闭式户 外照明灯具, 包括由灯壳和透光灯罩组合成的密封中空壳体、 以及设置在密封中空壳体内 的反光罩和 LED光源模块, 在反光罩与透光灯罩之间、灯壳与反光罩之间构成相对独立的 内、 外腔室, 反光罩上开设有安装孔和若干气孔, 气孔构成连通内、 外腔室的气流通道; 该发明为了避免引入外部空气的不洁造成热阻提高,延长电源供应器和 LED光源模块的寿 命,采用风扇强制对流,使空气在灯具壳体内、外腔室流动并穿梭于金属散热基板的网孔, 形成强制内循环散热。 该发明采用内部空气循环流动散热, 一方面结构复杂, 另一方面不 管内部空气循环有多快, 始终都是热空气在进行交换, 散热效果极不理想。

申请号为 201020250587. 9的发明专利中,公开了一种 LED路灯,包括灯壳、发光模块、 金属座、 两个或两个以上热管及多个散热鳍片, 灯壳包含相互罩合并形成有容置空间的下 盖及上盖, 下盖设有开孔, 并在远离开孔的一侧设有第一散热孔, 上盖对应第一散热孔处 设有第二散热孔, 发光模块容置在容置空间中, 并对应开孔配置, 发光模块包含电路板及 设置在电路板一侧面的两个或两个以上 LED灯,金属座包含相互叠接的第一板体及第二板 体, 且第一板体是热接触发光模块, 每一个热管包含吸热段及放热段, 吸热段水平穿设在 第一板体及第二板体之间, 放热段水平延伸在远离金属座的一侧边, 散热鳍片平行排列地 套接在热管的放热段上。 该实用新型为解决气体是自下盖的散热孔进入灯壳内部, 从而带 走散热鳍片上大量的热后,继续直线地向上流动,再从上盖散热孔流出,气体呈直线流动, 时其自然对流速度快的问题, 发光模块与散热鳍片分别设置在灯壳内的两侧边, 将发光模 块的容置空间与设有上下散热直通孔和散热鳍片的区域分开,通过热管将发光模块产生的 热量带走, 再通过散热直通孔和散热鳍片对热管散热, 一方面使路灯的结构特别复杂, 增 加制造成本, 另一方面大大增加路灯体积。

本发明的有益效果是:
1 ) 每个 LED发光单元包括一个单基色或两个双基色或三个三基色或四个三基色的 LED芯 片, 或 LED发光单元为固定在散热基座上的 LED灯珠。 由于在 LED发光单元间设有与 LED 发光单元的排列方式相匹配的散热直通孔, 每个 LED发光单元均与散热直通孔相邻, 一方 面减少了 LED发光单元密集排列在一起产生很高的结温,另一方面每个 LED发光单元产生 的热量可直接通过与其相邻的散热直通孔散发出去,尽可能使每个 LED发光单元的散热路 径最短, 每个 LED发光单元的散热路径相等或大致相等, 保证每个 LED发光单元的散热效 果都很好, 进一步减少了 LED发光单元产生很高的结温。 散热直通孔贯穿透光灯盖、 散热 基座, 散热直通孔的两端均与外界空气连通形成对流的气体散热通道, 所以非常有利于空 气对流。 LED光源在工作过程中产生的热量传导至基座上, 基座成为热的传导体和载体。 带有大量热量的基座会与散热直通孔内的空气进行热交换而加热散热直通孔内的空气, 由 于散热直通孔一般均是竖直方向,散热直通孔内的空气密度变小而上升并由散热直通孔的 上端部排出,这时位于基座下方的冷空气会不断地从散热直通孔的下端部进入散热直通孔 内, 从散热直通孔的孔壁吸收热量, 使基座冷却, 吸收了热量的热空气再不断地从垂直贯 通孔的上端部排出, 从而快速带走基座内的热量, 因此在基座内不会囤积大量热量而影响 LED光源的使用寿命、 散热效率高。 散热直通孔的加工非常方便、 快捷, 节约人力、 物力、 财力, 可大幅度降低散热装置乃至具有该散热装置的 LED灯具的成本。 LED发光单元容置 在容置腔内, 一方面避免外部带有湿气和有害化学物质等不洁空气造成 LED发光单元、 导 线和布图电路导电层受到污染、 热阻提高、 造成荧光粉、 硅胶材质劣化, 提高 LED发光单 元的寿命; 另一方面可以将 LED灯户外使用, 防止水等进入容置腔内。
2 ) 每个 LED发光单元只包含一个 LED芯片, 确保每个 LED芯片均与散热直通孔相邻, 使 每个 LED芯片产生的热量可直接通过与其相邻的散热直通孔散发出去, 尽可能使每个 LED 芯片的散热路径最短, 每个 LED芯片的散热路径相等或大致相等, 保证每个 LED芯片的散 热效果都很好, 进一步减少了 LED芯片产生高的结温。 采用 LED灯珠结构, 便于标准化分 工序生产, 组织生产方便。
3 ) 由于均设有定位透镜或成型透镜的塑胶件, 布图电路导电层可伸入定位透镜或成型透 镜的塑胶件内, 一方面导线可直接与布图电路导电层电性连接, 不再需要通过导电金属支 架将导线与布图电路导电层连接或通过接线脚从背离 LED 芯片的散热基座穿出与布图电 路导电层连接, 简化了结构和最大限度的减少中间环节的热阻, 散热效果好; 另一方面不 再需要焊接金属支架或接线脚与布图电路导电层电性连接, 不需要回流焊或波峰焊, 因此 封装胶体可以用树脂或硅胶等; 而且还可保证 LED芯片、 电性连接导线及其两个焊接端不 会暴露于空气中, 有利于使用的长寿命。 而需要回流焊或波峰焊时, 由于回流焊或波峰焊 的温度一般在 250C°或 280C°, 封装胶体就不可以使用树脂。 由于硅胶的价格远远高于树 脂, 透光性比树脂差, 因此本发明可以进一步节省成本, 提高 LED芯片的光学性能。 这种 COB 封装设计的优点在于每个 LED 芯片的电极都通过键合导线直接与布图电路导电层形 成欧姆接触,多路 LED芯片阵列的形成是通过散热基座与 LED芯片的电性连接装置实现电 气互联, 即可实现 LED芯片的串并联, 又可提高产品的可靠性和生产合格率。
4 ) 在散热基座上设有与散热基座一体成型的多个芯片固定凸台, 散热基座的面积大大的
大于芯片固定凸台顶部的面积, LED芯片通过固晶方式固定在芯片固定凸台上。 这样一方 面大大减少 LED 芯片产生的热量散发于散热气体即空气中的中间路径距离和大大增加了 与散热气体的接触面积, 大大减少了热积聚效应,可大大提高散热效率和使芯片保持于合 适的工作温度,从而保持芯片的长寿命及有效发光效率。 芯片固定凸台与散热基座一体成 型, 因此芯片产生的热量只透过散热基座就直接散发于空气中,故热阻小, 散热速度快, 不须借助其它散热件来散热, 散热效果便相当好。 由于有芯片固定凸台,使得电性连接导 线对 LED芯片发出的光线的抵挡阴影降到最低 ,利于光学二次优化!省去了现有的 LED支 架,也就是省去了 LED支架中的散热金属件, 及其电极金属脚等多层中间环节, 尤其减少 了散热金属件与散热基座的两个零件之间产生的高热阻,因此热阻小,导热快散热效果好, 结构简单可靠, 尤其芯片固定凸台与散热基座一体成型更有利于光源的设计与装配工艺, 又节省成本。 因此本发明结构简单可靠,零件少,厚度薄, 易于装配, 特别适用于对光源要 求大功率的场合。
5 ) 在定位透镜或成型透镜的塑胶件上设有避空孔, 使散热直通孔的两端均与外界空气连 通形成气体对流通道, 可以让 LED发光单元与散热直通孔获得最短的散热路径, 取得最佳 的散热效果。 定位透镜或成型透镜的塑胶件为一个, 可以减少固定柱的个数和增加单位面 积内 LED发光单元的个数。 散热直通孔侧壁上的散热凸台进一步增加散热面积, 提高散 热效果。
6 ) 条状或网状的散热鳍片, 一方面可以提高散热基座的强度, 使散热基座不易变形, 使 LED看起来更美观, 更重要的是增加与空气的散热接触面积, 提高散热效果。 散热直通孔 的侧壁到每个 LED发光单元的中心距离均相等, 散热均匀, 散热效果好。
7 ) LED发光单元成两排以上的直线排列具有日光灯管的发光效果, 照射效果好。
8 ) 散热鳍片, 可增加与空气的散热接触面积, 提高散热效果。 散热直通孔内侧的散热鳍 片, 一方面可提高散热效果, 另一方面可以装饰散热直通孔, 使 LED灯看起来更美观。 设 置冷却流道和冷却介质, 可进一步提高散热效果。 在冷却流道内充填冷却水, 由于水的比 热高, 又可通过对流散热, 可使 LED光源的热量迅速散发到水中, 被加热起来温度较高的 水会与接触空气的散热终端的温度较低的水形成对流,热量被交换到温度较低的接触空气 的散热终端通过散热终端迅速散发到空气中, 散热快, 可有效减少结温。 还有由于水的最 高温度为 100° C, 可避免 LED光源处的结温远远超过 100° C, 对于温差比较大的路灯等, 可减少 LED灯的骤冷骤热, 改善 LED灯的工作环境。
9) 通过在有些流道内侧壁间设有连接壁, 有些流道内侧壁间没有设连接壁, 使冷却流道 形成循环流道, 通过进液口将外面的冷却液体输进冷却流道内, 通过出液口将冷却流道内 的液体输出去,便于冷却介质的快速对流运动,散热效果更好。通过在设定流道内侧壁间、 设定的流道外侧壁和流道内侧壁间设有连接壁,使第一循环冷却流道完全环绕流道内侧壁 无死角, 不存在没有被冷却流道覆盖的散热单元, 散热效果更好, 更均匀。
10) 固定机构设置在 LED发光单元背离透光灯盖的一侧形成灯泡、 射灯、 吸顶灯、 吊顶灯 等。在 LED灯的顶部需要固定的情况下, 散热直通孔的两端仍然与外界空气连通形成对流 的气体散热通道。 固定机构设置在散热基座的一侧形成路灯、 台灯等。
11 ) 防尘盖可减少灰尘积聚在散热基座的顶面, 提高散热基座的散热效果。 在 LED灯的顶 部设有防尘盖的情况下, 散热直通孔的两端仍然与外界空气连通形成对流的气体散热通 道。 散热基座背离 LED发光单元的一侧为弧形, 可减少灰尘积聚在散热基座的顶面, 提高 散热基座的散热效果。
弹性卡扣 安装方式, 结构简单, 安装方便。采用灯座的结构, 结构简单, 安装方便、 固定可靠, 外观美观。
14)通过在有些流道内侧壁间设有连接壁, 有些流道内侧壁间没有设连接壁, 使冷却流道 形成循环流道, 通过进液口将外面的冷却液体输进冷却流道内, 通过出液口将冷却流道内 的液体输出去,便于冷却介质的快速对流运动,散热效果更好。通过连接壁和挡壁的结合, 使第一循环冷却流道完全环绕流道内侧壁无死角,不存在没有被冷冷却流道覆盖的散热单 元, 散热效果更好, 更均匀。
