模拟真火的电子发光装置及其模拟真火的方法
技术领域
本发明涉及一种电子发光装置。
背景技术
日常生活中，各种电子发光装置被广泛应用于玩具、家居装饰用品、礼品中。例如，人们原本是把蜡烛、煤油灯等当成一种照明灯具，但随着电光源的普遍使用，其照明功能逐渐淡化，人们对蜡烛、煤油灯等的需求也由实用性转为观赏性或情趣性，于是电子闪光蜡烛、电子蜡烛、仿真蜡烛和仿真煤油灯等各种电子发光装置也应运而生。这类电子发光装置的发光部分试图模拟蜡烛或煤油灯的发光形态，模拟其灯光闪烁、忽明忽暗等情景，但与真实的蜡烛或煤油灯点燃的真火焰相比，区别较大，视觉体验尚不够真实。
比如在专利号为200520035772.5、名称为《电子模拟闪光蜡烛》的中国专利中，采用一个形状模拟为真实火焰的火焰壳，内置LED发光元件，控制电路控制LED发光元件的点亮时序，使LED发光元件时亮时灭，视觉效果表现出光线忽明忽暗、闪动跳跃；以增强装置的趣味性和观赏性。

下面通过具体的实施例并结合附图对本发明作进一步详细描述。
实施例一：
本实施例具体产品为一个电子蜡烛，请结合图1、图2、图3、图4和图5所示，图1为本例电子蜡烛的外观示意图，整体模拟蜡烛的形状，包括：外壳1；壳体2，套装于外壳1内；机芯3和机座4，安装于该壳体2内。壳体2的顶部中间开设有一壳体通孔，一火焰片设于其中，火焰片伸出该壳体通孔的部分形状模拟为蜡烛点燃时的蜡焰，机芯上的发光元件发出的光线以一定的角度投射在该火焰片伸出通孔的部分，且该火焰片可以在自然风或设于机芯内的摆动机构的作用下自由晃动，如此，在一定的距离外看来起有如真正的蜡烛火焰摇曳跳动，非常逼真，几乎可以以假乱真。
如图2、图3、图4和图5所示，机芯3包括机壳、火焰片31、LED灯33和摆动机构等；机壳包括左盖38和右盖38′，二者形状对称，围合成一个大致为柱状的腔体，左盖38和右盖38′的顶部各有一个半圆的缺口，围合后，腔体顶部形式一个圆形的开口380；在左盖38和右盖38′侧壁上部各设计有一个内凹的、相对于侧壁倾斜一定角度的左缺口381和右缺口381′，左盖38和右盖38′围合后，形成一个向开口380倾斜、并与开口380相通的LED灯安装位；LED灯33安装于该安装位，LED灯33的纵向中心轴与腔体纵向中心轴成35度左右的夹角，同时LED灯33选择出射光线集中、出射角度较窄(7-10度)的LED发光元件，结合火焰片31的上片311的合适面积，这样可以保证LED灯33出射的光线保持投射在火焰片31表面，使光束亮度更高，且投射的光线在火焰片31表面成椭圆状，更接近真实的蜡焰形状。
请结合图6所示，火焰片31为片状，中间开设有一火焰片通孔310，以该火焰片通孔310为界，火焰片31的上片311形状模拟为蜡烛点燃时的蜡焰，下片312的配重比上片311略重，在自由状态下(自身重力作用于，非受外力作用时)，垂直悬挂；火焰片支杆32穿过火焰片31的火焰片通孔310，架设于机芯腔体的开口380处，火焰片支杆32呈V型，中间略凹，加之下片312的配重比上片311略重，可以保证火焰片31稳定地悬挂于该火焰片支杆32的最低点，在自由状态下(仅自身重力作用下，非受外力作用时)，火焰片处于垂直悬挂状态；同时，也使火焰片31更易在外力的作用下晃动，如此，火焰片支杆32被架设于机芯腔体的开口380处，且可以在外力如自然风的作用于任意晃动，但又能使火焰片31的上片311与LED灯33的光线出射方向保持相对固定的位置关系，以保证LED灯33的光线能够投射在火焰片31的上片311表面。火焰片31采用半透明材料制作，光线投射后，其背面也能透出部分光线，为提高仿真真实蜡烛火焰的效果，于火焰片31的上片311根部埋设一条铁丝，以模拟蜡烛的棉芯，在LED灯33投射在上片311表面的光线照射下，看起来有如一根蜡烛棉芯，使整体的视觉效果上更接近真实的蜡烛在燃烧。另外，火焰片支杆32在LED灯33的照射下，投射在火焰片31上片表面上，也会形成一条类似棉芯的黑影。
外壳1采用PVC等透明或半透明材料制作成管状，包括围合成管状的侧壁和横隔板10，横隔板10与管状侧壁的轴向相交，中间开设一横隔板通孔，用于从中伸出火焰片31的上片310；为了模拟蜡烛燃烧时蜡熔化的不规则变化，横隔板10以上部分的外壳侧壁制作成不规则的端面，前低后高，形成一个缺口；外壳1侧壁表面、横隔板表面涂覆烛蜡，使其效果上更接近真正的蜡烛。火焰片31的上片310由横隔板10的通孔伸出，并且其正面(光线的投射面)迎向缺口的低点，其反面被后面较高的外壳侧壁挡住，如此可以引导使用者摆放在一个较佳的角度来欣赏“蜡光”，即由火焰片31的上片310的正面、缺口的低点来欣赏，以保证本例的电子蜡烛的逼真效果。
为了保证火焰片的晃动效果，机芯设有一摆动机构，通过间接或直接对火焰片保持一个作用力，使其保持晃动或摆动。如图4、图5所示，本例中的摆动机构采用一磁力机构，包括磁铁组39、联动片35、联动支杆34和线圈37等，该磁铁组39包括第一磁铁、第二磁铁和第三磁铁；联动片35活动穿设于联动支杆34中，联动支杆34架设于机芯腔体内，联动支杆34呈V型，中间略凹，使联动片35被定位于联动支杆34中间的最低点中；在不受外力的情况下，可以自由垂直悬挂在机芯腔体内；联动片35的上下端部分别粘接或嵌接第二磁铁和第三磁铁；火焰片31的下端部粘接或嵌接第一磁铁，与联动片35的上端部处的第二磁铁相对的极性可以相异或相同，即二者会产生相吸或排斥的力；线圈37被通过卡环36扣接于一PCB副板上，并置于联动片35的下端，与联动片35的下端部处的第三磁铁相对。
火焰片31产生晃动或摆动的工作原理是：通过控制电路输出振荡，该线圈37在通电时产生与联动片35的下端部处的第三磁铁极性相异的磁场，使二者产生相斥，联动片35因此而向任意侧边摆动；再通过联动片35上端部处的第二磁铁与火焰片31下端部处的第一磁铁的相吸或相斥作用，使火焰片31摆动；在该线圈37断电的时间段内，火焰片31又在自身重力作用下自由下落，并在惯性势能作用下，向另一方向继续摆动，至到线圈37再次通电，线圈37的磁场力再通过联动片35改变火焰片31的惯性运动，再重复下一次晃动循环。
如图3、图4所示，机座4包括电池座41、电池盖42、PCB主板43和电池弹片44等；电池弹片44装于电池座41形成电池室，用于安装电池45；PCB主板43安装于电池座41上，位于电池室一侧，PCB主板43上布设有控制电路和电源开关，PCB主板通过导线与LED灯33、安装线圈37的PCB副板以及与电池弹片电连接；电池盖42活动盖设于电池座41底部，可以取下更换电池室内的电池。机芯3安装于机座4之上，其中的安装有线圈的PCB副板与PCB主板43电连接；电池座41的周缘可以和壳体2的底部扣合，也可以通过螺栓与壳体2螺接。壳体2为空心圆柱状，其外径大致与外壳1的内径相当或略大，可以和外壳1紧配合；其顶部开设有一个用于与机芯3配合的通孔，机芯3被收纳于壳体2的腔体内，其中的火焰片31的上片311由该通孔上伸显露出来。
如图7所示为本例的电路原理图，下面结合图7对本例的工作原理作说明。
电源部分：电池提供的能量经过开关SW1送到升压变换器U1输入脚，由第五电容C5、第二电感L2、升压变换器U1、第三电容C3和第八电阻R8等元器件组成的升压电路，从升压变换器U1的第5脚输出一个3.3V稳定的电压供给微控制器U2、LED灯LED1(在上述的结构说明中被表述为LED灯33，采用类似真火颜色的暖白灯)和线圈L1等。
开关SW1接通为电路供电时：当微控制器U2得到3.3V电压后开始工作，当微控制器U2第5脚(PB1)的电压高于1.82V时，微控制器U2控制第8脚(PWM/PCO)输出开40ms、关630ms的脉冲方波，该方波控制MOS管Q1与线圈L1振荡产生磁场，联动片35的下端部处的磁铁产生的磁场与线圈产生的磁场方向相同(同为N极或同为S极)，使线圈排斥磁铁，然后磁铁带动联动片35做左右摇摆的动作，联动片35的上端部处的磁铁产生的磁场与火焰片31的下端部处的磁铁产生的磁场方向相反，因为联动片35与火焰片31控制在一定距离，使联动片35带动火焰片31做左右摇摆的动作；同时微控制器U2控制第3脚(PB3)输出高电平，经过第十电阻R10给三极管Q2基极提供大约0.6V电压，三极管Q2导通后使LED灯LED1点亮；然后将光斑以35度的角度投影在火焰片，在线圈的带动下，从远处观看此火焰片，与实际蜡烛点亮的火焰很相似，非常逼真。最佳观看距离大于1米，角度小于120度。
开关推到定时功能档时：当微控制器U2第1脚(PA3)为低电平时，一部分微控制器U2控制第8脚(PWM/PCO)停止500ms后又输出开40ms、关630ms的脉冲方波，控制MOS管Q1与线圈L1振荡产生磁场，联动片上的下部分磁铁产生的磁场与线圈产生的磁场方向相同(同为N极或同为S极)，使线圈排斥磁铁，然后磁铁带动联动片35做左右摇摆的动作，联动片35的上端部处的磁铁产生的磁场与火焰片31的下端部处的磁铁产生的磁场方向相反，因为联动片35与火焰片31控制在一定距离，使联动片35带动火焰片31做左右摇摆的动作；同时微控制器U2控制第3脚PB3停止500ms后(即LED1闪烁一次)又输出高电平，经过第十电阻R10给三极管Q2基极提供大约0.6V电压，三极管Q2导通后使LED灯LED1点亮；另一部分由晶振X1、第一电容C1和第二电容C2组成的振荡电路，给微控制器U2提供标准时钟信息，从LED灯LED1闪烁一次后微控制器U2计时器开始计时，经过5小时后，微控制器U2将控制第8脚(PWM/PCO)与第3脚(PB3)输出低电平，使火焰片停止摆动，LED灯LED1熄灭。再经过19小时后微控制器U2将控制第8脚(PWM/PCO)开40ms，关630ms的方波与PB3输出高电平，使火焰片开始摆动，LED灯LED1点亮。完成一个周期时间为24小时，以这种方式一直循环工作。直到电池能量耗尽或拨动开关SW1为止。
当电池电压低于1.62V时，无论在开关SW1“接通档”或在“定时档”LED灯都会熄灭，同时火焰片停止摆动，控制电路进入睡眠状态。直到更换新电池后才会恢复工作。
将开关推至断开档，升压变换器U1、微控制器U2没有得到电池提供的能量而停止工作。LED灯会熄灭，同时火焰片31停止摆动。
实施例二：
请参考图8所示，本例中，对实施例一的摆动机构作减法，取消中间的联动片35部分，线圈37靠近火焰片31下端部，通过线圈37产生与火焰片31的下端部处的磁铁极性相异的磁场，使二者产生相斥，火焰片31也可保持晃动状态。
实施例三：
本例中，对实施例一中的机芯3其中的摆动机构，采用本例的结构，请参考图9所示，包括挂绳301、摆动块302、旋转块303、马达固定块304和马达305；挂绳301上端挂设于火焰片31的下端部，挂绳301下端连接摆动块302，马达305被马达固定块304固定于机芯的机壳内，旋转块303与马达305的输出轴固接；自然状态下(仅自身重力作用下，非受外力作用时)，摆动块302依靠自身的重量垂挂在挂绳301上，摆动块302的下端部接触旋转块303；当马达305驱动时，旋转块303会不断碰撞到摆动块302，摆动块302的不停晃动带动火焰片31作无序的晃动。
请参考图10所示，为本例的电路原理图，由微控制器U2第8脚(PWM/PCO)控制马达M1转动，实现整个摆动机构的运作。
实施例四：
本例中，对实施例一中的机芯3其中的摆动机构，采用本例的结构，请参考图11所示，包括连杆401、转动块402、马达固定块403和马达404；火焰片31的中部开设有一个卡位，连杆401上端卡接于火焰片31的该卡位中，连杆401未端与转动块402的外壁相接触；转动块402的高度不规则，中间设有盆腔，在盆腔侧壁设有一挡块4021，火焰片31的下端部伸入盆腔中，自然状态下该挡块4021与火焰片31的下端部相接触；马达404被马达固定块403固定于机芯的机壳内，转动块402与马达404的输出轴固接；当马达404驱动时，转动块402被带动，其外壁会不断碰撞到连杆401未端，挡块4021也会不断地(间歇)碰撞火焰片31下端部，使火焰片31作无序的晃动或摆动。
实施例五：
本例中，对实施例一中的机芯3其中的摆动机构，采用本例的结构，请参考图12所示，包括连接块501、旋转块502、马达固定块503和马达504；火焰片31的下端部设有一个卡扣313，与连接块501的扣位5010相扣接；连接块501为L型，其远离扣位5010的一端设有一卡扣5011，与旋转块502上的扣位5020相扣接；马达504被马达固定块503固定于机芯的机壳内，旋转块502与马达504的输出轴固接；当马达504驱动时，旋转块502带动连接块501转动，连接块501带动火焰片31晃动。
实施例六：
本例中，对实施例一中的机芯3其中的摆动机构，采用本例的风扇结构，请参考图13所示，一风扇固定于机芯的机壳内，位于腔体底部，包括风轮601、马达固定块602和马达603，风轮601出风方向朝上；火焰片31的下端部折起一个角度，形成一个面迎风轮601出风方向的挡板314；当风扇启动时，火焰片31的挡板314正面迎风，使火焰片31在风力作用下不停晃动。
以上各例，均可以采用可充电电池供电，并于机座PCB主板上增设一充电控制电路，使本发明中的电子蜡烛能够采用插接充电器或充电座进行充电。以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
