Definitions

  • the invention and the lighting device in particular, relates to a lighting fixture with an anti-glare device.
  • the three kinds of lighting fixtures such as street lamps, car headlights and downlights, produce an effective illumination beam, while the cone-shaped reflectors cannot meet the design requirements due to the surface treatment process, resulting in the formation of glare by the second or more reflected light and the uncontrollable scattered light.
  • Glare Although the light of the street lamp is very soft, it can illuminate the road for passers-by, but the glare it produces can make people unable to see the road. It is one of the main sources of light pollution in the city; because the brightness of the headlights is much higher than that of the street lamps. Therefore, the upward and outward glare of the cone-shaped effective illumination light is stronger and more glare than the glare of the street lamp.
  • the object of the present invention is to provide an illumination beam completely controlled within an effective illumination range and a critical projection angle, to make the illumination of the effective illumination range more uniform, and to change the direction of the glare beam into effective illumination light, and the anti-glare effect is good and effective.
  • Light fixtures with anti-glare devices that eliminate light pollution.
  • the object of the present invention is achieved as follows:
  • the present invention comprises a lamp housing, a reflector bowl, a bulb and a lamp leather, characterized in that an anti-glare device is mounted in front of the bulb.
  • the anti-glare device is composed of a convex lens, a concave through-milling and a H) cylindrical shading device.
  • the left end of the light-shielding circumference is fixedly connected with the right end of the lamp housing, and the convex lens and the concave-transparent town are both juxtaposed in the shading cymbal, and the convex lens is mounted on the shading.
  • the concave lens is mounted outside the shading enclosure.
  • the lower half of the inner wall of the shading is coated with a dark light absorbing layer.
  • the anti-glare device is composed of a single lens, a single lens is mounted between the bulb and the lamp leather, and the axis of the single lens is in line with the illuminator of the bulb.
  • the single lens is a single convex lens or a single concave lens.

Description

说明书 带防眩光装置的照明灯具
技术领域
本发明及照明设备, 尤其是涉及一种带防眩光装置的照明灯具.
背景内容
路灯、 汽车大灯和筒灯这三种照明灯具在产生有效照射光束的同时, 锥状 的反光体因表面处理工艺不能满足设计要求,造成了二次以上反射光和不可控 制散射光形成了刺眼的眩光. 路灯的光线虽然很柔和, 能给路人照亮道路, 但 它产生的眩光会使人看不清道路, 是城市的主要光污染源之一; 由于汽车大灯 的亮度远比路灯高, 所以在锥状的有效照射光外围向上、 向外的眩光比路灯的 眩光更强烈、 更刺眼, 因而在汽车交会时, 对面被照射的司机和行人常常眼前 , 一片发花, 根本就看不清前面 «和车辆情况, ¾乱中常常导致操作错误, 极 容易发生交通事故; 数量众多的筒灯常用于宣内装饰中, 目前原有的简灯^已 采用反光革来控制照射区域, 但因数量众多, 还是容易造成强烈眩光, 不经过 二次防眩处理, 其产生的眩光也不可忽略. 从附图 1、 2、 3中可见, 照射光线 X1-X2区域为合理照射范围, 照射光线 XI- Dl、 X2-D2区域为应排除的眩光光束 范围.
专利号为 02142339. 3的发明专利: 汽车防眩目灯是采用光栅来防眩光, 这种结构光损较大, 结构也较复杂, 没有广泛的实旄意义.
发明内容
本发明的目的在于提供一种将照射光束完全控制在有效照明范围及临界 投射角内、使有效照明范围照度更均匀、 并可将眩光光束改变方向成为有效照 射光、 防眩光效果好、 能有效消除光污染的带防眩光装置的照明灯具.
本发明的目的是这样实现的: 本发明包括灯外壳、 反射碗、 灯泡和灯革, 特征是在灯泡前面安装有防眩光装置.
所迷防眩光装置由凸透镜、 凹透铣和 H)筒形的遮光圏组成, 遮光围的左端 与灯外壳的右端固定连接, 凸透镜和凹透镇均并列安装在遮光囷内, 凸透镜安 装在遮光围内的里面且靠近灯泡, 凹透镜安装在遮光围内的外面. 在遮光囤的 内壁下半部分涂有深色的吸光层.
所迷防眩光装置由单透镜组成, 单透镜奏装在灯泡和灯革之间, 且单透镜 的轴线与灯泡的发光体处于同一直线上.所述单透镜为单凸透镜或单凹透镜中
