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。
