Description

发光二极管单色灯泡
本实用新型涉及装饰用灯，具体是一种发光二极管单色灯泡。
目前，公知的彩色灯泡多采用白炽灯加彩色玻壳组成。其存在耗电大、亮度低、寿命短、及发热量大的缺点。近年人们在不断探索采用发光二极管的彩色灯，如专利号为97226456.6的彩色半导体变色灯，其将三基色LED置于灯泡内，在外部控制电路的控制下实现光色的任意组合。但其体积较大，成本较高，在目前社会通用的用电方式下使用不便，不利于产品的推广。
本实用新型的目的在于克服现有技术上述不足，提供一种能显示红、绿、蓝、青、黄、紫、白七色任一种色彩的发光二极管单色灯泡。
本实用新型的另一个目的是提供一种适合社会普遍家庭使用的、结构一体化的、节能型发光二极管单色灯泡。
本实用新型单色灯泡包括：灯罩、灯头、外壳、发光二极管及驱动电路，其特征在于：所述的灯罩是混色灯罩，所述的驱动电路是直流恒流源，发光二极管组连接于直流恒流源的输出端，全部电路部分置于外壳内，构成一体化的发光二极管单色灯泡。
本实用新型发光二极管单色灯泡无变压器，结构与电路一体化，体积小，重量轻，成本低廉，可直接和传统的灯口配接，使用安全可靠，适合规模生产。
其耗电量少，寿命长，耗电3～4W的七色灯的照度相当于带外玻壳罩的25W白炽灯的照度。能够制成显示红、绿、蓝、青、黄、紫、白七色任一种色彩的单色灯泡，广泛适用于酒店、饭店、家庭、医院、防火、工业、制动控制显示、楼宇控制显示、交通控制显示等领域。
以下结合附图对本实用新型详细描述。
图1是本实用新型单色灯的结构示意图；
图2是本实用新型实施例的电路原理图。
如图1所示，该单色灯主要由灯罩(1)、发光二极管组的合成发光光源(2)、驱动电路板(3)、外壳(4)和灯头(5)组成。由于发光二极管法线方向上发光强度值最大，三种基色的发光二极管交叉组合排列在线路板上，它们发射出红、绿、蓝光色是不能均匀混色的，本单色灯采用具有混色功能的混色灯罩，实施例中所述的混色灯罩是乳白色不透明玻璃灯罩或者乳白色不透明塑料灯罩，灯罩可以制成球形、半球形、圆柱形等其它形状，借助灯罩内壁光滑程度发生光漫反射，实现红、绿、蓝、青、黄、紫、白七色任一种单色光效果。
图2是本实用新型实施例的电路原理图。直流恒流源由整流桥、串联于整流桥交流输入端的电容，以及并联于整流桥两输出端的滤波电容组成。限流电容器C1、整流桥VD1和滤波电容器C2组成直流恒流源，与电容器C1并联的电阻R1用于电容放电，电容器C1串联于整流桥VD1的输入端，滤波电容器C2连接于整流桥VD1的输出端，发光二极管组连接于整流桥VD1的输出端。
发光二极管组是由若干个单基色发光二极管串联支路并联构成的，发光二极管串联支路一般由6个或9个发光二极管组成，再由8～16个串联支路并联组成一个发光二极管组。为了配出绿、红和兰三基色外的青、黄、紫、白单色，发光二极管组可以由两种或者三种基色发光二极管组成，即发光二极管组由这些基色发光二极管串联支路并联构成。发光二极管组还可以由白色发光二极管串联支路并联构成。总之，根据需要组合配色，本实用新型能够制成显示红、绿、蓝、青、黄、紫、白七色中任一种色光的单色灯泡。使用时，将本单色灯泡拧入家用普通灯口，通电即可发出稳定的单色光。
