Description

一种节能灯灯头及节能灯 技术领域
本发明涉及电子产品应用领域，尤其涉及一种节能灯灯头及节能灯。
背景技术
节能灯又称为自镇流荧光灯或紧凑型荧光灯，它利用的是气体放电原理，具体是通过镇流器给灯管灯丝加热，灯管灯丝上涂有一些电子粉，在加热达到一定温度时，灯管灯丝开始发射电子，电子碰撞氩原子产生非弹性碰撞，氩原子碰撞后获得了能量又撞击汞原子，汞原子在吸收能量后跃迁产生电离，发出紫外线，紫外线激发荧光粉发光。由于节能灯不存在白炽灯那样的电流热效应，荧光粉的能量转换效率很高，故具有光效高、节能效果明显、寿命长、体积小、使用方便等优点。
现有的节能灯灯头一般是将电路装置和节能灯灯管封口容置在同一个灯头壳体中，该电路装置中的电子元器件主要包括镇流器，该电路装置与节能灯灯管封口端的电极电连接。在节能灯工作时，节能灯灯管中的灯丝的温度达到摄氏一千多度以上，其节能灯灯管封口上的温度也有一百多度，因此其产生的热量需要很好地散发出去，以免热量的淤积对节能灯灯头中电路装置中的电子元器件的性能造成影响，比如电子元器件镇流器等。
现有的节能灯一般通过在节能灯灯管封口与电子元器件所在的电路装置间加装隔热板和导流凹槽、散热暗孔等，使节能灯的灯管产生的热量受到隔离和导流排到节能灯外面大气中。但是随着电子元器件的集约化发展，这种散热技术加大了技术工艺上实施的复杂度，其隔热层采用了隔热材料，增加了材料成本，同时如果采用的隔热材料性能不佳或者长期使用造成失效，热量仍然能够穿透隔热层影响到电路装置，进而导致电子元器件的性能下降，寿命缩短。
发明内容
鉴于上述现有技术存在的问题，本发明实施例提出了一种节能灯灯头和节能灯，通过该灯头壳体分别容置电路装置和节能灯灯管封口使其被分离在不同的部位，使节能灯灯管封口处的温度对电路装置中电子元器件性能的影响较小。
为解决上述问题，本发明实施例提出了一种节能灯灯头，包括灯头壳体，所述灯头壳体包括第一壳体和第二壳体，所述第一壳体容置电路装置，所述第二壳体容置节能灯灯管封口，所述节能灯灯管封口端的电极与所述电路装置电连接，所述第二壳体至少部分错开设置在所述第一壳体外周之外。
所述第二壳体至少部分错开设置在所述第一外壳外周之外，包括第二壳体部分错开设置在所述第一壳体外周之外以及第二壳体全部错开设置在所述第一壳体外周之外。
所述第二壳体与所述第一壳体一体成型;在所述电路装置与所述节能灯灯管封口之间设置有隔热层。
所述节能灯灯头包括分体成型的第一壳体和第二壳体，所述第二壳体与所述第一壳体相连接;所述第一壳体与所述第二壳体通过连接件固定在一起，或者所述第一壳体与所述第二壳体粘合连接在一起。
在所述第二壳体上设置有散热孔;所述节能灯灯头还设有灯罩。
本发明还提出了一种节能灯，包括灯头壳体、电路装置以及节能灯灯管，所述灯头壳体包括第一壳体和第二壳体，所述第一壳体容置电路装置，所述第二壳体容置节能灯灯管封口，所述节能灯灯管封口端的电极与所述电路装置电连接，所述第二壳体至少部分错开设置在所述第一壳体外周之外。
所述第二壳体至少部分错开设置在所述第一外壳外周之外，包括第二壳体部分错开设置在所述第一壳体外周之外以及第二壳体全部错开设置在所述第一壳体外周之外。
所述第二壳体与所述第一壳体一体成型；在所述电路装置与节能灯灯管封口之间设置隔热层。
所述节能灯灯头包括分体成型的第一壳体和第二壳体，所述第二壳体与所述第一壳体相连接；所述第一壳体与所述第二壳体通过连接件固定在一起，或者所述第一壳体与所述第二壳体通过粘合连接在一起。
在所述第二壳体上设置散热孔；所述节能灯灯头还设有灯罩。
相应的，本发明实施例还提出了一种节能灯灯头，其特征在于，包括灯头壳体，所述灯头壳体包括第一壳体和第二壳体，所述第一壳体容置电路装置，所述第二壳体容置节能灯灯管封口，所述节能灯灯管封口端的电极与所述电路装置电连接，所述第一壳体与第二壳体分离可活动连接，所述第二壳体至少部分错开设置在所述第一壳体外周之外。
所述第二壳体至少部分错开设置在所述第一外壳外周之外，包括第二壳体部分错开设置在所述第一壳体外周之外以及第二壳体全部错开设置在所述第一壳体外周之外。
所述第一壳体与所述第二壳体通过卡设固定连接在一起，或者所述第一壳体与第二壳体通过螺纹紧固在一起。在所述第二壳体上设置散热孔。
实施本发明实施例，该灯头壳体包括第一壳体和第二壳体，第一壳体容置有电路装置，第二壳体容置节能灯灯管封口，其第二壳体至少部分错开设置在第一壳体外周之外，那么节能灯通电之后，其节能灯灯管封口所散发的热量不会直接影响第一壳体中电路装置的电子元器件，从而减少灯管的热量对电路装置中电子元器件性能的影响。在该节能灯灯头上，通过在电路装置与节能灯灯管封口之间设置隔热层，可以阻止节能灯灯管封口上的热量向电路装置上进行横向扩散，也可以通过在第二壳体上设置散热孔来加快节能灯灯管封口上的热量散发。这里的第二壳体与第一壳体是一体成型的，也可以分体式连接在一起的，满足不同用户需求，本发明还提出了一种可活动连接的节能灯灯头，其通过可活动连接，在灯头坏掉或灯管坏掉时，其只需要更新对应的部件即可完成，更有利于优化资源的使用。

为了减少节能灯灯管封口横向扩散热量到电路装置中，还可以在电路装置与节能灯灯管封口之间设置隔热层，该隔热层可以由绝热材料制成，通过这种设置，可以避免节能灯灯管封口的热量横向扩散到第一壳体内，从而避免影响到第一壳体中电路装置的电子元器件的性能。
为了减少外壳上节能灯灯管封口的局部受热量，还可以在第二壳体上设置散热孔，通过该散热孔加快节能灯灯管封口上的热量的散发。

这里的灯管32可以是普通的U型灯管，也可以是螺旋型灯管，其与该第二壳体31相匹配。
图4示出了本发明实施例中的节能灯灯管32的结构示意图，其包括了灯管封口35和电极34，该灯管封口35在安装时容置在第二壳体31中，该节能灯灯管32通过电极35与第一壳体31中容置的电路装置电连接。
图5示出了本发明实施例中的带灯罩的节能灯的结构示意图，其在灯头上套一灯罩33，该灯罩33可以是卡设在灯头壳体上，也可以通过其它方式固定在灯头上。
相应的，图6还示出了一种分离式的节能灯的结构示意图，其包括灯头和灯管32，该灯头包括灯头壳体、电路装置等等，该灯头壳体包括第一壳体30和第二壳体31，其中，第一壳体30容置有电路装置，第二壳体31容置节能灯灯管封口，电路装置与节能灯灯管封口电连接在一起，该第一壳体30和第二壳体31分离可活动连接，第二壳体31至少部分设置在第一壳体30的外周之外，这里的灯管32与第二壳体31中的节能灯灯管封口端的电极电连接，在工作时，第一壳体30中的电路装置通过第二壳体31向灯管32供电，使灯管发光，通过这种第一壳体30与第二壳体31分别容置不同的电子元器件，其灯管32所散发的热量不会直接影响到第一壳体30中电路装置的电子元器件，从而减少灯管32的热量对电路装置中电子元器件性能的影响。
需要说明的是，这里的第一壳体30和第二壳体31分离可活动连接，其可以通过卡设固定在一起，也可以通过螺纹紧固在一起，当然也不限于上述方式。
这里的灯管32可以是普通的U型灯管，也可以是螺旋型灯管，其与该第二壳体31相匹配。该第二壳体31上还设置有散热孔，用于散发第二壳体31上的热量。
综上所述，该灯头壳体包括第一壳体和第二壳体，第一壳体容置有电路装置，第二壳体容置节能灯灯管封口，其第二壳体至少部分设置在第一壳体外周之外，那么在对灯头所接的节能灯管通电之后，其所散发的热量不会直接影响到第一壳体中电路装置的电子元器件，从而减少灯管的热量对电路装置中电子元器件性能的影响。
在该节能灯灯头上，通过在电路装置与节能灯灯管封口之间设置隔热层，可以阻止节能灯灯管封口上的热量向电路装置上进行横向扩散，也可以通过在第二壳体上设置散热孔来加快节能灯灯管封口上的热量散发。这里的第二壳体与第一壳体是一体成型的，也可以分体式连接在一起的，满足不同用户需求，本发明还提出了一种可活动连接的节能灯灯头，其通过可活动连接，在灯头坏掉或灯管坏掉时，其只需要更新对应的部件即可完成，更加有利于优化资源的使用。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属于本发明所涵盖的范围。
