Abstract

一种多焦点投光灯具,适合于广场、港口、车站等 大面积照明。目前通用的照明灯具反光体为光滑曲 面,这种灯具的照射距离近,覆盖面积小,照度也低。
本实用新型所提供的灯具采用两组反光体,由多 种曲面构成,主反光体的横截面形状为桃形,副反光 体的反光面由多个反光面组成的瓦棱形,使灯具的发 光效率比现有灯具提高26%,而且光分布均匀,覆盖 面大,眩光小。

Description

本实用新型为一种多焦点投光灯具,适合于广场、港口、车站等大面积照明。
目前国内生产的投光灯的反光体为光滑曲面,这种灯具的照射距离近,覆盖面积小,照度也低。
本实用新型的目的在于提供一种新型投光灯具,它可以克服现有技术所存在的缺点。
本实用新型的目的是这样实现的:它由灯体和反光体组成,其特征是反光体由主、付二组反光体构成。主反光体的横截面形状为桃形,反光面由多种曲面构成,付反光体的反光面是由多个反光面组成的瓦棱形。
本实用新型造型独特,设计合理,光线经主、付二组反光体的曲面反射,使灯具的发光效率比国内现有灯具提高26%,而且光分布均匀,覆盖面大,眩光小。
本实用新型的具体结构由以下实施例给出:
图1是本实用新型一种具体实例的结构示意图。
图2是图1所示的实施例的纵向剖视图。
参照图1、2,详细说明本实施例的具体结构。
图中1为主反光体,它的横截面为桃形,反光面是由多种曲面构成的,其中包括光滑弧面10、条形瓦棱面11、菱形立体拼块12。图中2为付反光体,付反光体2是由24个小反光面拼成的瓦棱形,付反光体2与灯体3插装,并用压片压紧。主反光体1和灯体3通过固定圈8紧固在一起,固定圈8与主反光体1铆接,与灯体3用螺母13联接,灯体3是由后壳体5和支架7组成,后壳体5内装有灯头9,支架7的铰接处装有刻度盘14,刻度盘14可以显示出灯具旋转的角度。

Claims (3)
