I've been using a Philips Wake-up Light for this in the past four years and it helps me a lot in winter. It's not perfect but it's a lot better than waking up to a screaming alarm clock :-). Recently I replaced most of the lights in my house with Philips Hue lights and I was pleased to find out that these can also be used as wake-up lights. This seems to work even better for me, possibly because the bedroom lights up more evenly (as opposed to the wake-up light right next to my bed).
