Description
技术领域
本发明涉及LED灯技术领域，特别是涉及一种全周光LED球泡灯。
背景技术
人们在平时生活当中时常会利用闲暇的时间欣赏音乐，以此来舒缓情绪，达到降压的作用。人们经常会利用手机、MP3等移动终端来播放音乐，而手机作为人们随身携带最多的工具，其被使用的也最多。由于直接开启手机进行音乐的听取，音量太大会影响到其他人，尤其是在办公室午休或者其他多人的房间内时，此时需要用耳机插到手机上，利用耳机来听取音乐，这样就不会影响到其他人。为了使用方便，现在很多耳机都是线控式耳机，即在耳机线上可以直接进行音量的调节，快进或者下一首，以及对移动终端音乐功能的开启或者关闭。
目前大部分线控耳机都是采用电阻分压的方式进行按键检测，当正在使用线控耳机上的麦克风MIC通话时，如果按下按键调节音量，此时会引起MIC偏置电压的变化，从而产生很刺耳的噪音---
pop 声，影响通话质量。
LED 具有光效高、体积小、无汞污染、使用寿命长等优点，在生活中已经逐步得到普及，但是LED
是点光源，具有一定的集光性，其发光角度多为按一定的锥度向前，而不能如传统的球泡灯一样各个方向均能发光，且传统的球泡灯的侧面的发光角一般大于270°，一般认为侧面的发光角大于270°即达到全周光的效果。
LED
灯具一般需配置散热器，而常用的散热器为铝质、铜质制成，且LED芯片贴装在该类的散热器上时，散热器会遮挡一定的光线，不仅造成光源的损失，而且会对灯具侧方、侧后方造成一定的暗角或亮度不足，达不到全周光的效果。
目前，LED
灯多是把LED灯珠焊接在铝基板或陶瓷基板上，再把铝基板或陶瓷基板和支座连接，因此，LED灯珠和支座之间隔了一层铝基板或陶瓷基板。由于铝基板或陶瓷基板的存在，增大了LED灯珠和支座之间的热阻，降低了散热的功效，导致LED
灯珠的使用寿命大大缩短。此外，铝基板的制造成本高、制作工艺复杂、电绝缘性能较差；陶瓷基板需要高温烧结成型、工艺复杂、价格昂贵、机械性能差且易碎。因此，目前的LED灯的结构复杂、制造成本高、制作工艺复杂、散热效果不好且达不到全周光的效果。
发明内容
本发明要解决的技术问题是提供一种全周光LED球泡灯，灯芯更换方便，散热效果好，实现全周发光，各方向发光均匀。
为了解决上述技术问题，本发明采取以下技术方案：
一种全周光LED球泡灯，包括灯座、散热器和灯芯，底座内设有驱动电路，所述散热器下端与灯座连接，散热器上端套装在灯芯内，灯罩装在散热器上且将灯芯容纳在内，灯芯与驱动电路电性连接，灯芯表面设有喷涂层，该喷涂层上
经激光蚀刻和化学镀后形成有电路层，灯芯上设有LED灯珠，该LED灯珠的引脚与电路层连接，该LED灯珠的底部紧贴于喷涂层。
所述散热器包括热塑料外壳和铝导热套，铝导热套为台阶柱结构，铝导热套下部插装在热塑料外壳内，该铝导热套上部插装入灯芯内。
对于灯芯和散热器的形状设置，本发明有以下三种较佳的实施方式。
方式一：所述灯芯外表面呈圆柱形，灯芯内部为圆柱形空腔，散热器的铝导热套上部设为圆柱形，该铝导热套的圆柱形上部插装入灯芯内部的圆柱形空腔。
方式二：所述灯芯外表面呈球形，灯芯内部为圆柱形空腔，散热器的铝导热套上部设为圆柱形，该铝导热套的圆柱形上部插装入灯芯内部的圆柱形空腔。
方式三：所述灯芯的外表面为六棱柱形，灯芯的内部为六棱柱形空腔，散热器的铝导热套上部设为六棱柱形，该铝导热套的六棱柱形上部插装入灯芯内部的六棱柱形空腔。
进一步，所述喷涂层的厚度为5μm～300μm。所述电路层的厚度为5μm～300μm。喷涂层及电路层厚度根据球泡灯的功率来决定，如果其厚度小于5μm，则达不到所需用电功率、安全载流量及所述的发明效果；喷涂层或电路层厚度大于300μm，则会造成资源浪费并增加成本。
所述灯芯与散热器间通过螺丝锁紧，或者通过卡扣锁紧，或者以螺纹方式装接。
所述灯芯为柔性基板。
所述灯芯表面的喷涂层由可选择金属化的粉末涂料喷涂而成。
本发明结构设计合理、简单，制作工艺简单、可靠，制作成本低，散热效果好，延长了LED
球泡灯的使用寿命，能达到全周光照明的效果，各方向发出均匀的光，灯芯拆装简便，可随时随意更换，其他部件可循环使用，既环保又实用。

具体实施方式
为了便于本领域技术人员的理解，下面结合附图对本发明作进一步的描述。
本发明揭示了一种全周光LED球泡灯，如附图1和2所示，一种全周光LED球泡灯，包括灯座1、散热器2和灯芯3，底座内设有驱动电路，所述散热器2下端与灯座1连接，散热器2上端套装在灯芯3内，灯罩4装在散热器2上且将灯芯3容纳在内，该灯罩4为透明灯罩，灯芯3与驱动电路电性连接，灯芯3表面设有喷涂层，喷涂层由可选择金属化的粉末涂料喷涂而成，该喷涂层上
经激光蚀刻和化学镀后形成有电路层，灯芯上设有LED灯珠31，该LED灯珠31的引脚与电路层连接，使LED灯珠31与电路层间形成导通电路，该LED灯珠的底部紧贴于喷涂层，灯芯为柔性基板。由于LED灯珠的底部紧贴着喷涂层，LED灯珠31产生的热量通过灯芯3传导至散热器2进行散热，散热效果好，有效延长LED灯的使用寿命且绝缘安全。
此外，LED灯珠的数量可根据灯芯的表面面积和应用场合的需求进行灵活设定，并无具体限制。柔性基板可选择
高耐热、高导热的绝缘塑料制成，提高耐热性能和导热性能。喷涂层的厚度设定为5μm～300μm，电路层的厚度设定为5μm～300μm，以达到最佳的整体匹配效果。LED灯珠的功率可选择为0.5～10W。喷涂层及电路层厚度根据球泡灯的功率来决定，如果其厚度小于5μm，则达不到所需用电功率、安全载流量及所述的发明效果；喷涂层或电路层厚度大于300μm，则会造成资源浪费并增加成本。
此外，散热器2包括热塑料外壳21和铝导热套22，铝导热套22为台阶柱结构，即散热器2的上端为外伸凸起状，铝导热套22下部插装在热塑料外壳21内，该铝导热套22上部插装入灯芯3内，将灯芯3顶起。由于外壳由热塑料制成，具有较佳的散热性能。热塑料外壳21的下部与灯座1连接，可以通过螺纹方式装接，或者其他安装方式，此为常规手段选择，在此不再详述。灯芯与散热器之间可通过螺丝锁紧，如在灯芯下部设置一个或者多个螺丝垫孔，在散热器上相应位置设置螺丝孔，通过螺丝将灯芯与散热器锁紧连接在一起。灯芯与散热器之间也可以通过设置一些卡扣，利用卡扣直接扣紧，如在灯芯上设置凸起扣，在散热器上设置相应的卡槽，将凸起扣顶入卡槽内即实现灯芯与散热器的稳固装接。或者在散热器的上部外表面设置螺纹，在灯芯的内部设置相应匹配的螺纹，通过螺纹旋接实现灯芯与散热器的安装连接。需要说明的是，以上列举的灯芯和散热器的装接方式并非是限定，在基于此思路下，能够实现灯芯和散热器安装连接的方式都可以采用，在此不一一罗列。
灯芯3上的LED灯珠31发光发亮时会产生热量，该热量通过喷涂层传导至灯芯3，再由灯芯传递至铝导热套22，热量经铝导热套传递给热塑料外壳，从而与外界空气交换热量，实现热量的散发，散热效果好。
此外，本发明对于灯芯和散热器的形状还进行了优化设置，具体有以下三种较佳的实施方式。
实施例一，如附图1和2所示，所述灯芯3外表面呈圆柱形，灯芯3内部为圆柱形空腔，散热器2中的铝导热套22的上部设为圆柱形，铝导热套22的圆柱形上部插装入灯芯3内部的圆柱形空腔，铝导热套22上部将灯芯支撑顶着，使得灯芯完全位于灯罩内，使得LED球泡灯的发光角度大于270°，达到全周光照明的效果。
实施例二：如附图3和4所示，所述灯芯3外的表面呈球形，灯芯3内部为圆柱形空腔，散热器2的铝导热套22上部设为圆柱形，铝导热套22的圆柱形上部插装入灯芯3内部的圆柱形空腔，铝导热套22上部将灯芯支撑顶着，使得灯芯完全位于灯罩内，使得LED球泡灯的发光角度大于270°，达到全周光照明的效果。
实施例三：如附图5和6所示，所述灯芯3的外表面为六棱柱形，灯芯3的内部为六棱柱形空腔，散热器2的铝导热套22上部设为六棱柱形，该铝导热套22的六棱柱形上部插装入灯芯3内部的六棱柱形空腔，铝导热套22上部将灯芯支撑顶着，使得灯芯完全位于灯罩内，使得LED球泡灯的发光角度大于270°，达到全周光照明的效果。
以上对本发明的较佳实施进行了具体说明，当然，本发明还可以采用与上述实施方式不同的形式，这些都不构成对本实施方式的任何限制，熟悉本领域的技术人员在不违背本发明精神的前提下所作的等同的变换或相应的改动，都应该属于本发明的保护范围内。
