A shape-memory polymer foam is disclosed, which is formed by kneading a shape-memory copolyester with a polymeric material having a relatively lower crystallinity in a weight ratio of 15:85 to 85:15 and then conducting a foaming process. The shape-memory copolyester is a random copolymer formed from a dicarboxylic acid mixture and a diol in excess through esterfication and polycondensation. The dicarboxylic acid mixture includes 30-99 mol % of an aromatic dicarboxylic acid and 70-1 mol % of a straight aliphatic dicarboxylic acid of C4-C10. The diol includes a straight aliphatic diol of C2-C10.

An illuminating device using light-emitting diodes as its light source is provided. The light-emitting diode module is disposed on a heat-dissipating substrate with at least one heat-dissipating surface, so that the heat generated by the working light-emitting diodes can be rapidly removed. In this case, the illuminating device simultaneously has the advantages of high luminosity, low power consumption, good light-emitting efficiency, and long lifetime.
