The present invention is a control method of a lighting device that includes a housing (10); a reflector (20) arranged in the housing (10); lamp assemblies (101) (102) generating a light source by applying power and respectively arranged in the reflector (20); a stabilizer (300) supplying the power to each lamp assembly (101) (102); a dimming controller (400) turning on or off at least one of the lamp assemblies (101) (102) and controlling the stabilizer. The dimming controller (400) generates the light source by applying the power to the lamp assemblies (101) (102) in a first time range and generates a light source by applying the power to one of the lamp assemblies (101) (102) in a second time range, and cuts off the other in order to performing a dimming process. The dimming controller (400) saves energy by dimming one of the lamp assemblies (101) (102) in a time range of low power consumption, but also the duration of the lamp assemblies (101) (102) is reduced so that the lifetime is extended. |
