A currently-available white LED can be modified to freely set a colour temperature as well as to improve a colour rendering property. A correction-colour LED or LEDs having a peak wavelength in a specific wavelength region in association with a white LED are provided to make a colour temperature-regulable LED which permit the correction of not only a colour temperature but also a colour rendering property by means of colour-mixture of the correction-colour LED and the white LED considering the colour temperature and a spectrum distribution of the white LED. The colour temperature-regulable LED is especially useful as an shadowless operating light, a living room light and a decorative light <；IMAGE>；
