Abstract:
An LED module according to the present invention includes: a mounting substrate; a first LED group including a plurality of LEDs mounted in a first light-emitting area extending in a first direction on the mounting substrate; a second LED group including a plurality of LEDs mounted in a second light-emitting area located outside the first light-emitting area; a dam material surrounding a periphery of the second light-emitting area; a first fluorescent resin coating the first LED group and causing the first light-emitting area to emit light having a first color temperature; and a second fluorescent resin coating at least the second LED group and causing the second light-emitting area to emit light having a second color temperature higher than the first color temperature, and viscosity of the first fluorescent resin is higher than viscosity of the second fluorescent resin.
