当您乔迁新居或家庭装修时,一定会想到如何搞好家庭照明,使您的生活环境更加美观舒适。由于家庭照明涉及到光学、建筑学、心理学等多方面,是一门综合艺术,要想搞好并不容易。下面简单介绍一下这方面的知识。 一、家庭照明常用光源。家庭照明光源有两种,即自然光和灯光。白天一般用自然光,晚上则用灯光。电光源是目前普遍使用的灯光光源,常用的有白炽灯,俗称电灯泡;另一种是低压水银荧光灯,即日光灯。 白炽灯是美国人爱迪生1878年发明的,是人类第一代照明电光源。虽然至今已有100多年的历史,但由于它结构简单、使用方便、价格低廉、光色较好、便于调光和配制各种装饰灯具,故仍被广泛使用。白炽灯的缺点是发光效率低,10～20流明/瓦,使用寿命短(1000小时左右)。

Since home lighting involves many aspects such as optics, architecture, and psychology, it is an integrated art and it is not easy to do well in order to do well.

Natural light is used during the day and light is used at night. Electric light source is a commonly used light source, incandescent lamp is commonly used, commonly known as electric light bulb; the other is low-pressure mercury fluorescent light, that is, fluorescent lamp. The incandescent lamp was invented by American Edison in 1878 and is the first generation of human illumination light source. Although it has a history of more than 100 years, it is still widely used due to its simple structure, convenient use, low price, good light color, easy dimming and preparation of various decorative lamps. The disadvantages of incandescent lamps are low luminous efficiency, 10 to 20 lumens/watt, and short life (about 1000 hours).
