The lighting design requirements of the library, let's take a look!
The library is a place for learning, so the lighting of the library should ensure that there is enough brightness for reading. At the same time, the library lighting should choose a light source close to the natural light effect, avoid stroboscopic and glare, improve the comfort of learning, and also protect our eyesight. Library lighting is generally divided into visual lighting and ambient lighting. Library lighting should meet the requirements of finding books and reading; at the same time, good library lighting, like general classroom lighting, should also have a certain auxiliary role。
1. General requirements for library lighting:
In library lighting, visual tasks mainly occur on vertical surfaces, and the vertical illuminance at the spine should be 200lx. The lighting of the aisles between the bookshelves should use special lamps and be controlled by separate switches.
2. Library lighting selection:
The library lighting generally adopts indirect lighting or fluorescent lamps with multi-level emission light. For precious books and cultural relics library, lamps with filtering ultraviolet rays should be used. Generally, the installation height is low, and there should be certain measures to limit glare. The protection angle of open lamps should not be less than 10, and the distance between lamps and flammable objects such as books should be greater than 0.5m.
In addition, it is not advisable to use sharp light-cutting lamps for library lamps, otherwise shadows will be formed on the upper part of the bookshelf, and direct lamps and mirror reflection lamps without cover should not be used, because they can cause reflections of bright book pages or bright printed words and interfere with vision.
3. Installation method of library lamps
The special lamps for bookshelf aisle lighting are generally installed above the bookshelf and aisle, and most of them are ceiling installations. Conditional can be embedded installation. The lamps and lanterns are installed on the bookshelf as a whole, which has greater flexibility, but necessary electrical safety protection measures should be taken. For open-shelf bookstores and bookshelves arranged on one side in the reading room, lamps with asymmetric light intensity distribution characteristics can be used to project lighting to the bookshelves. This installation method can not only achieve a good effect of the lighting of the bookshelf, but also will not cause glare interference to indoor readers.
The reading room has a large area, so it is advisable to use two or more embedded fluorescent lamps or LED panel lamps to increase the light output area of the lamps, improve the quality of indoor lighting, and make it easier for us to find the books we need. Bookshelf lighting requires uniform vertical brightness up and down, which is convenient for finding books on each shelf. Grid spotlights can be installed above the center of the passage between the bookshelves to achieve lighting effects.
The library is a good place for us to learn and grow our knowledge, and the atmosphere here is more suitable for learning. We should pay more attention to the lighting design of the library, so that the learning environment will be better!
