某图书馆新馆照明节能设计
随着我国经济的持续快速增长,导致电力供应需求急剧攀升,供电不足的矛盾日益突出。因此,合理地节约用电已经成为全社会共同追求的目标。图书馆照明用电量在整个图书馆用电量中占有相当大的比例,这就要求图书馆照明的设计要满足节能、降耗、高效的绿色照明要求。本文以某图书馆新馆照明设计为例,具体阐述其在照明灯具的选择、自然采光与空间照度设计、调光与照明控制系统的应用与节能的关系。 1 灯具的选择 1.1 光源选择 (1) 白炽灯 白炽灯应用极为广泛。它是第一代电光源的代表,属于热辐射光源,即利用钨丝被加热时白炽体高温辐射发光的原理制成的光源。白炽灯的缺点是发热量大,发光效率低,使用寿命短等。极大部分热辐射为红外线,发光效率约为11%,红外线、热能消耗分别约占总能耗69%、20
