Development of Soft X-Ray and Vacuum Ultraviolet Spectrum Sources;

A new excitation source was developed.

Usual lighting sources are compared to educe their applicability in different condition,considering the particularity of bulk grain wharf,an example is offered to show the selection of lighting source and luminaries,which provide some reference for bulk grain wharf lighting design.

The influence of different illuminants on the color between natural teeth and two types of metal ceramic restorations

They were illuminant,visual field,background,and luminance.

At present,there are some problems to have unfavorable influence in illuminate trade in China,such as unreasonable selection for illuminant,simple & single protective function,inconvenience for replace of illuminant.

Effect of light source on the experiment of liquid crystal light valve;

Research of turbidity measuring influence caused by two different light source;

The paper reviewed the recent advancement of illuminating light sources and illuminating science and technology.

Fluorescent lamps are the most efficient light sources for indoor lighting, but they may eventually be in danger of the enviroment because of the mercury contained.

Characteristics of some common-used electric lamp-house and suitable places for them to be used are intro-duced at the viewpoint of energy saving.

It was very important to choose appropriate lamp-house to excitated photosenzitisers and decided the effection of PDT.

This paper introduce each projector lamp-house and its specification in a nutshell.
