Description

一种筒灯
技术领域
本发明涉及一种筒灯，特别是涉及一种天花筒灯。
背景技术
为了提高筒灯的工作性能和延长筒灯的工作寿命，通常需要对筒灯设计散热结构，传统的散热方法是将光源板安装在壳体底面，尽量利用筒灯的壳体(也就是后盖)来对光源板的热量进行散发，后来，有人在筒灯的壳体(也就是后盖)上加开气流通孔从而加速筒灯内部热气的扩散，可进一步提高筒灯的散热速度。
但是，现在有些地方、国家有规定楼板内要填充防火棉，并要求筒灯壳体(也就是后盖)的表面温度不得超过80度。实际安装使用时，楼板内的防火棉包住筒灯壳体会极大地减小筒灯后部的热对流，筒灯壳体外表面温度居高不下，也无法满足相关规定，存在一定的安全隐患。
发明内容
本发明提供了一种筒灯，其克服了背景技术所存在的不足。本发明解决其技术问题所采用的技术方案是：
一种筒灯，包括后盖、前环、透光板、光源板、电源器件，所述后盖是底面开口的壳体结构，所述前环的中部设有通孔，所述透光板设置在所述前环的通孔当中，所述前环盖住所述后盖的开口形成装配室，所述光源板和电源器件设置在所述装配室内并电连接，包括位于装配室内的支撑件，所述支撑件与所述前环连接，所述支撑件与所述后盖的侧壁和上顶面隔空，所述光源板安装在支撑件上，所述光源板靠近所述前环设置并且不与所述后盖接触，所述光源板的热量可通过支撑件传递给前环并由前环向大气散发。
本技术方案与背景技术相比，它具有如下优点：
光源板靠近前环设置，支撑件和光源板不与后盖的侧壁和上顶面接触，光源板的热量通过支撑件和前环散发到大气当中，最大程度防止光源板的热量传递到后盖上，有效地控制后盖的温度，防止后盖温度过高，提高在防火棉环境下使用的安全性。
附图说明
下面结合附图和实施例对本发明作进一步说明。
图1绘示了本发明一种筒灯的立体分解示意图。
图2绘示了本发明一种筒灯的另一立体分解示意图。
图3绘示了本发明一种筒灯的立体示意图。
图4绘示了本发明一种筒灯的剖视示意图。
具体实施方式
请参照图1至图4，本发明的一种筒灯，包括后盖10、前环20、透光板30、光源板40、电源器件50。所述后盖10是底面开口的壳体结构，包括侧壁12和上顶面14。所述前环20的中部设有通孔22，所述透光板30设置在所述前环的通孔22当中。所述前环20盖住所述后盖10的开口形成装配室60。所述光源板40和电源器件50设置在所述装配室60内并电连接。筒灯还包括位于装配室60内的支撑件70，所述支撑件70与所述前环20连接，所述支撑件70与所述后盖的侧壁12和上顶面14隔空。所述光源板40安装在支撑件70上，所述光源板40靠近所述前环20设置并且不与所述后盖10接触，所述光源板40的热量可通过支撑件70传递给前环20并由前环20向大气散发。
由于光源板40靠近透光板30设置，光源板40不与后盖10接触，支撑件70也不与后盖10的侧壁12和上顶面14接触，即支撑件70、光源板40与后盖10的侧壁12和上顶面14隔空，并且光源板40远离后盖10的上顶面14，光源板40、支撑件70的热量通过前环20和透光板30向大气散发，因此可以最大程度地防止光源板40、支撑件70的热量传递给后盖10的侧壁12和上顶面14，从而减小后盖10的侧壁12和上顶面14的温度。
优选地，所述前环20设有伸入到所述后盖10开口内的定位环24，所述定位环24围成所述通孔22，所述定位环24的上端面设有插槽26。所述支撑件70包括底板72及连接在底板边缘的围边74。所述光源板40连接在所述底板72的下表面，所述围边74插入到所述插槽26当中。光源板40的热量通过支撑件70传递到定位环24，插槽26的内外圆周面能够有效地进行散热，因此，插槽23与围边74的接触面积越大越好。
优选地，所述支撑件70的材料是铝合金。这样，支撑件70热传导性非常好，其本身就是一个散热元件。
优选地，所述透光板30内缩设置在所述通孔22当中，所述透光板30与所述定位环24的内表面卡接在一起。所述透光板30与所述前环20的下表面之间存在间距H。间距H越大，散热越快。
优选地，所述电源器件50连接在所述底板72的上方。所述电源器件50不与所述后盖10接触。筒灯还包括设置在所述装配室内并连接在支撑件70和电源器件50之间的电源隔板80。电源器件50不与所述后盖10接触，即电源器件50同样与后盖侧壁和上顶面隔空，同样可以防止电源器件50的热量直接传递给后盖10。
优选地，筒灯还包括设置在所述装配室内的隔热挡件90，所述隔热挡件90位于所述电源器件50和后盖10的上顶面之间。所述隔热挡件90包括挡片91和连接在挡片边缘的侧边92。由于热气流是朝上运动，隔热挡件90隔空所述电源器件50和后盖10的上顶面14，有效降低后盖10的上顶面14的温度。隔热挡件90的挡片91与后盖10的上顶面14的距离越大隔热效果越好。
本发明的筒灯安装好之后，防火棉包住所述后盖10的外表面并且所述光源板40处于工作状态时，所述后盖10外表面的温度低于80度。
以上所述，仅为本发明较佳实施例而已，故不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。
