In this paper,an LED solar simulator by using six different peak wavelengths and high power LEDs has been developed.In order to achieve effective radiance of one sun intensity,six kinds of high power LEDs are used for the light source.In the design of the irradiance non-uniformity on the effective irradiated area,combined with the optical characteristics of the large angle light emitting of LEDs,multiple spot light of optical system is used in the design.

炎热的夏季，人们不仅会遭受高温燥热的煎熬，还容易受到疾病威胁，那你知道夏季最怕什么危害吗？以下6大危害要极其小心！ 一、颈椎最怕吹 颈椎对着空调吹，周围的软组织会产生病变，形成肌肉和皮下组织的慢性炎症，造成颈部持续痉挛、后背酸痛等后果。建议室内空调温度不要低于25摄氏度，肩背部不要直对着空调，如果温度不能自行调节，可以在肩上搭个披肩，晚上洗个热水澡。 二、喝水最怕快 由于气温高，身体缺水速
