Description

一种直下式背发光灯具 技术领域
本实用新型属于室内照明技术领域，涉及一种室内灯具，特指一种直下式背发光灯具。
背景技术
随着社会的快速发展，人们已经不再满足单一色温单一亮度的LED光源，例如，夏季时，当客厅内的灯发出低色温的暖光时，在炎热的夏天配上暖光会让人觉得更加的闷热，客厅的灯发出高色温的冷光则会令人感到凉爽舒适；而冬季时，当客厅内的灯发出高色温的光源则会令人感到阴冷不适，此时需要的是低色温的暖光；常见的客厅内的灯一般都平板灯，发出的色温一般都是固定色温，因为客户的需求不同，有些客户可能需要高色温光的灯，有些客户则是需要低色温光的灯，有些则是需要中色温光的灯，销售商为满足客户的需求都会在自家仓库内囤有三种色温的灯，销售商常常因为仓库内积压的灯具售卖不出去而愁眉不展，这样无形之中拔高了仓库管理的压力，灯具的闲置也会降低资源使用率；
市面上出现了一种灯具其通过同一种颜色的灯珠串联或并联组成，多路由冷色到暖色不同色调的灯珠组件集成在一起组成灯。其每一灯珠只能发出一种颜色的光，如当需要发出冷光时，暖色光的灯珠则处于断电闲置状态，反之亦然。对于该种灯具，假如需要的光照强度50w，则需要分别配备50w的冷光灯珠组和50w的暖光灯珠组(以 冷光、暖光二种色调为例)，如此，实际上需要装配的就是100w的灯珠模块，才能在保证光照强度的同时实现变色功能，虽然能够大幅度的降低销售商的仓储压力，但是其结构较为复杂，制造成本较高，维修不便，销售利润较薄，销售商宁愿多囤灯具也不愿采购及生产该种灯具。
