A device called Solar Trap for concentrating and collecting the solar energy is disclosed. Said Solar Trap employs, firstly, the principle of the light funneling as means for concentrating the sun light and secondly, the principle of the repeated incidence as means for enhancing the absorption of the concentrated sun light. The principle of the light funneling is realized by means of one or more of light funnels comprising a pair of reflecting surfaces arranged in V or U shaped cross sections wherein the funnel angle is greater than six degrees and the funnel opening is wider than three inches. The principle of repeated incidence is realized by means of a heat absorbing fin disposed at the apex zone of the light funnel wherein the funnel angle is equidivided to two equal halves by said heat absorbing fin, which fin transfers the heat to the heating medium circulated through a heating vessel attached to said heat absorbing fin or converts the sun light directly to the electrical energy as in the case of the heat absorbing fin made of the photo-voltaic cells.
