Description

一种LED灯
技术领域
本实用新型一种LED灯。
技术背景
现有技术中，LED灯是由灯头、灯体、驱动电路、散热体、LED灯板和罩壳组成。灯头固定在灯体的下端，灯体上端套入散热体内，驱动电路安装在灯体中，LED灯板安装在散热体上并通过驱动电路与灯头连接，罩壳罩在LED灯板上并安装在散热体的上端。工作时，LED灯板上的LED通电发光，光线透过罩壳，实现照明。
但是，上述结构的LED灯，因为LED灯板呈平面状，发光角度大约为120°，照射范围小，所以发光照明效果较差。有鉴于此，本发明人对现有LED灯的结构进行改进，本案由此产生。
实用新型内容
本实用新型的目的在于提供一种LED灯，以提升照明效果。
为了达成上述目的，本实用新型的技术方案是：
一种LED灯，由灯头、灯体、驱动电路、散热体、第一反光体、LED灯板、第二反光体和罩壳组成；灯头固定在灯体的下端，灯体上端套入散热体内，驱动电路安装在灯体中，第一反光体套在散热体的上端周围，第一反光体的外表形成反光筒面，LED灯板安装在散热体的顶面，LED灯板通过驱动电路与灯头连接，第二反光体安装在LED灯板上，第二反光体朝向LED灯板的一面形成反光曲面，反光曲面上形成若干通孔，罩壳罩在第二反光体、LED灯板、第一反光体、散热体和灯体上并安装在灯体上。
所述LED灯板是由MCPCB（Metal Core PCB，金属基印刷电路板）和若干LED组成，若干LED连接在MCPCB上。
所述灯体具有下连接端、上连接端和中间筒，中间筒的顶部形成卡扣，散热体具有连接套和安装座，安装座上开设卡孔，灯头固定在灯体的下连接端，连接套罩在中间筒上，通过卡扣卡入卡孔中使安装座固定在中间筒的顶部，第一反光体套在连接套上，第二反光体和LED灯板通过螺丝固定在安装座上，罩壳固定安装在上连接端。
采用上述方案后，本实用新型因为在灯罩中还增加了第一反光体和第二反光体，当通电后LED点亮时，部分光线透过第二反光体的通孔向外发送，部分光线通过第二反光体的反光曲面进行光反射发送，通过控制第二反光体的通孔间隙及反光曲面弧度，可达到在0°～135°范围内（垂直轴对称）的任何角度之间光强差异不超过20%，且在135°～180°区间至少有5%总光通量的光强照射效果。总之，本实用新型大大提升了照明效果。
