The invention discloses a cold-heat-electricity hydrogen-light combined supply system driven by low-grade heat energy. The cold-heat-electricity hydrogen-light combined supply system comprises a flash evaporator, a water vapor high-pressure expansion machine, an organic working medium heater, an injection refrigeration system, an injection type organic Rankine flash evaporation system, a light production system, an electrolytic hydrogen production system and an expansion compression cold-heat-electricity combined supply system. Low-grade heat energy fluid enters a flash evaporator, generated steam enters a steam high-pressure expansion machine to do work and output electric power, generated liquid enters an organic working medium heater to heat an organic working medium of a jet type organic Rankine flash evaporation system, and dead steam of the steam high-pressure expansion machine is coupled with a jet refrigeration system; the expansion compression combined cooling and power system is coupled with the inj
