Abstract
A dual color temperature-controlling system, electrically connected to a brightness controlling module of a street light, includes a power supply controlling module, a switching module, a first and a second color temperature light emitting modules, and a comparing module. The switching module is electrically connected to the power supply controlling module. The first and the second color temperature light emitting modules are electrically connected to the switching module. The comparing module is electrically connected to the switching module. A voltage-type operating signal sent from the brightness controlling module is received by the comparing module for comparison, and a switching signal is then sent to the switching module. The switching module is switched for lighting up the first or second color temperature light emitting module depending on the switching signal. Thereby, color temperature of the street light is changed so as to enhance safety of road occupant.
