The secret of light environment design has to be said about museum! - Lighting network

Guide language: the light environment is an important measure of museum, art gallery level indicator. In order to properly keep the exhibits, should as far as possible from optical radiation damage. However, in order to give the audience and create a good environment for the visit, visit the places need to maintain relatively high illuminance level again. So, lighting design should be reasonable to effectively solve the contradiction.

museum and art gallery has become a symbol of national or regional comprehensive strength, its basic function is a physical collection, scientific research and social education. Light environment is an important measure museum and art gallery level indicator. In order to properly keep the exhibits, should as far as possible from optical radiation damage. However, in order to give the audience and create a good environment for the visit, visit the places need to maintain relatively high illuminance level again. So, lighting design should be reasonable to effectively solve the contradiction. Because of the museum collections are susceptible to optical radiation, reason should be in lighting design, attention should be paid to the following three questions: the light, the heating effect of the radiation to the target, will receive its thermal radiation at the same time, long-term thermal radiation can lead to the destruction of the museum collection. Thermal radiation, therefore, should be through the following ways to control lighting: 1, using infrared lens filters the infrared radiation of the light source, reduce the according to content of fever; 2, using infrared radiation or rarely infrared radiation light source; Excluding infrared radiation LED lighting lamps and lanterns, part of the halogen lamp is equipped with infrared filter glass, these two kinds of lighting lighting products are suitable for those places. Second, the radiation of light aging effect to the target, also receives its ultraviolet radiation, can cause long-term exposure is a collection of aging, embrittlement. Therefore, should be through the following ways to control lighting ultraviolet radiation: 1, using uv lens filters the ultraviolet radiation of the light source; 2, use no ultraviolet radiation, or rarely ultraviolet radiation light source. Three, control light in addition to control lighting of the infrared and ultraviolet radiation, still need to control the light, especially high light sensitivity, can be strengthened in the following two aspects: 1, a low illumination light, general standard collection of illuminance value between 50 ~ 150 lx; 2, control the exposure time, reduce exhibits exposure or lower illuminance values. Museum/gallery lighting mainly includes the following two parts: first, display lighting display lighting to deal with the balance of the whole and local, the balance of exhibits and the background in terms of color and intensity of illumination. At the same time, demands a high color rendering of light, avoid dazzle, specific requirements include: 1, the uniformity: images of low illumination and high intensity of illumination than not less than 0. 7, especially big picture is not less than 0. 3; 2, contrast: in order to make the object emerged from its background, than should be according to its background brightness 3:1 to 4:1; 3, visual adaptation: eyes are to be according to the brightness of content adaptation level related to view the average brightness. Therefore, we should limit the brightness of the regional scope, the ratio of the maximum brightness and minimum brightness shoulds not be more than 4:1; 4, color: display in the drawing, colored fabric, exhibits, such as high requirements for color differentiation, color rendering index should be adopted for the Ra > 90 lighting light source or lamps and lanterns; 5, glare: by lighting design, control a glare and secondary reflected glare; Highlights of 6, focus lighting: for item, by focusing on lighting. 2, display space lighting inside the space of light environment should be combined with the architectural design, interior design and display design into consideration. At the same time, fully consider the combination of natural light and artificial lighting, display space lighting to create attractive space environment, and not distract visitors for exhibits. Therefore, exhibits the surface intensity of illumination and the museum space environment is suitable for the ratio of the intensity of illumination is 3:1. Museum and art gallery is a place for indoor lighting is the most difficult to grasp and design, should fully consider various requirements, choose lamps and lanterns. Attached: the museum gallery showroom lighting standard ( With reference to GB - 50034 2004 'building lighting design standard') Category reference plane and high illuminance value ( lx) Light sensitive exhibits: textiles, ZhiXiuPin, painting, paper, coloured drawing or pattern, tao ( Stone) , dyed leather and animal specimens displays 50 light sensitive surface exhibits: painting, egg white, not dyed leather, horns, bone products, ivory products, wood products and lacquer ware and other products surface of 150 is not sensitive to light displays: metal products, stone implements, ceramics, the treasure jade stone, rock specimens, enamel, glass, enamel products such as exhibits 300
