HYBRID LIGHTING APPARATUS

摘要

A hybrid lighting apparatus is provided to implement a required indoor atmosphere by controlling the brightness and a color temperature of a line source and a point source. A hybrid lighting apparatus includes a light guide plate(10), a fluorescent lamp part(20) in one side of the light guide plate, an LED module in other side of the light guide plate, a power supply unit(40) supplying the power to the fluorescent lamp part and the LED module, and a dimming circuit controlling the power supplied to the fluorescent lamp part and the LED module. A fine uneven pattern(15) with a light reflection function is formed in the rear side of the light guide plate. The light reflected from the pattern is radiated through the front side of the light guide plate. The fluorescent lamp part is installed at one side of the light guide plate. The fluorescent lamp part is formed to emit with the first color temperature to the light guide plate. A plurality of LED modules are installed in other side of the light guide plate. A plurality of LED modules emits to the light guide plate in a second color temperature. The power supply unit supplies the power to the fluorescent lamp part and the LED module. The dimming circuit controls the power supplied to the fluorescent lamp part and the LED module. The hybrid lighting apparatus has a color temperature range between the first color temperature and the second color temperature.
