Background technique

In the educational activities of kindergarten, environment in exploitation infant intelligence, promotes infants'personality as a kind of Hidden Curriculum Aspect increasingly attracts people's attention.Environment is important educational resource, should founding and utilizing by environment, effectively rush Into the development of child, wherein lighting environment is exactly an important component of educational activities environment.

Kindergarten mainly for 3-6 years old child, they are also in the body development stage, it is most important that eyes also exist In development, if design of the kindergarten on light is not reasonable, it is possible to will cause light pollution, be caused to the eyes of child Certain damage, therefore generally emphasize to avoid the occurrence of too dazzling light in progress kindergarten's Decoration Design Shi Douhui.

With the increasing of social investment, currently, the classroom of many kindergartens is by melting recreation room, bedroom, washroom etc. one Body multipurpose room is designed or is transformed.The activity single compared to the past, teaching classroom purposes, new integrated classroom has The functional characteristics of fusion is played, learned, therefore, in Environment Design especially Lighting control, occurs designing with traditional classroom illumination Different demands.

Traditional kindergarten's classroom illumination system in actual moving process, be only capable of by simple several switches to lamp into Row control.The arrangement of these lamps is usually to optimize by the illumination requirement of desktop, it is assumed that application scenarios be also religion Each main region all light in room is gone out entirely.

With the appearance and development of intelligent lighting technology, independent, light modulation lamp control means very easy acquisition and reality It is existing.Therefore, in recent years, there is regulation in classroom illumination design specification mostly, it is desirable that conditional school preferably combines naturally Daylighting selects intelligent lighting system to realize permanent illumination control and brightness adjustment control.For example, middle and primary schools and the children in Sichuan Province It in the classroom illumination design standard DB51/T-2015 of youngster garden, just explicitly points out, conditional classroom, is arranged by classroom function and illuminates Situation, natural lighting situation and classroom operating mode preferably take subregion, grouping, control measure with an automatic light meter, will also be by the classroom It is with an automatic light meter that illumination requirement combination natural lighting selects intelligence control system to realize.

Kindergarten classroom can improve indoor sense of closure and constriction by the way that sunlight is introduced directly into interior, simultaneously also Natural light is supplemented by artificial light, so that the interior space be made to seem more warm natural.Compared to traditional Bang-bang control, the multiple colors that interior is showed with light color change can also bring more enjoyment to child.Meanwhile in child In the illumination of garden, indoor photochromic design is also the important element that children are linked up, for example, child when learning performance, needs To be similar to the lighting environment of stage, need in demonstration area than facade illumination more under common scenarios, with enhance identification function, Improve the communication effectiveness of demonstration or performance.In this way, can just make child experience the aesthetic feeling of the interior space during use, more greatly Limit allows child to be accepted, and changes the life style of child and the quality of life of child.
