苹果手机赚钱的捕鱼游戏大全Relicase provide a variety of lighting solutions for showcases, any type of lighting must meet the requirements of the Codes for Design of Lighting in Museums. This approach creates lighting that can create the perfect museum ambience, give prominence to exhibits and, at the same time, allow for the highlighting of other secondary objects. The light sources should be concealed and the illumination level and angle of light adjusted. To ensure exhibits are not damaged, infrared light and ultraviolet light must be filtered out in order to prevent heat gain.
苹果手机赚钱的捕鱼游戏大全Fluorescent light is the most common choice for uniform or general illumination due to its high color rendering and life-like colors. An extensive range of choices for different types of fluorescent lighting models and lighting temperatures are available and can come with intelligent or manual dimming. A fluorescent tube generates high levels of ultraviolet radiation, which can be filtered out by laminated glass diffuser layers or by using UV fitering film.
General lighting or accent lighting can be achieved with low voltage halogen lighting. It allows the easy replacement of lens accessories, is dimmable, and you can choose the right angle of light by selecting different light sources and conveniently adjusting lighting positions. Special ultraviolet light filtration treatment is also required.
苹果手机赚钱的捕鱼游戏大全This is the preferred choice for museum lighting. Fibre optic lighting became hugely popular after it was introduced to museums in the 1990s and has since become widely applicable. This is because fibre optic lighting systems offer many advantages. This type of system is composed of three basic components: a light source or light projector (a halogen light source, metal halide light source and LED light source are available), glass fibre optic harness and end-light fixture.
The light source can be placed at a position outside the showcase and away from exhibits so the heat it generates will not affect the exhibits. The fibre optic harness is able to effectively conduct visible light while eradicating ultraviolet light; this means the resulting light does not contain ultraviolet light or heat. The number and position of end-light fixtures can be combined in any way so as to achieve the optimum lighting effect. You can easily adjust the angle, focal point and direction of light to meet the lighting requirements of exhibits of different types and sizes.
LED light sources can come in the form of light strips, spotlights or track-mounted spotlights. With the development and improvement of LED technology, the range of applications of LED lights has widened considerably. LED lighting's low electricity consumption, extremely long service life and wide variety of installations provides diverse exhibition applications.
