Abstract

Provided is a lighting device which can be easily attached. Two partition plates (14,14) are opposite to each other on a rectangular body frame (10) along the longitudinal direction of the body frame (10). A power-supply unit (30), a connection terminal (40), grips (50), etc. , are juxtaposed with LED modules (20) in a compartment defined between the partition plates (14). Further, the LED modules (20) are mounted in the compartments defined between each of the partition plates (14) and each of the longitudinal edges of the body frame (10). Namely, two groups of the LED modules (20) are juxtaposed on the body frame (10) so that the power-supply unit (30), the connection terminal (40), and the like are provided between the two groups of the LED modules (20).

Description

technical field [0001] The invention relates to a lighting device which can simplify installation work. Background technique [0002] In recent years, instead of fluorescent lamps and incandescent lamps, lighting devices using light-emitting diodes, which are known for power saving and long life, as light sources have been developed. In a lamp of such a lighting device, a substrate (LED module) on which a plurality of light emitting diodes (LEDs) are mounted, a driving circuit (power supply circuit) for driving the LEDs, and the like are mounted. [0003] When the lighting device using the above-mentioned LED is installed on the ceiling, in order to make the light-emitting surface on the lower side, a two-layer structure is adopted, that is, the LED is placed on the lower side to install the substrate, and components such as the drive circuit and the power supply circuit will be included. Or a circuit board or the like is arranged on the back side (upper side) of the LED mo...
