    Abstract: A back light device includes a first light emitting block including a plurality of light emitting modules connected in series to each other; a power supply module that applies a driving voltage to the first light emitting block; a first power switch connected to the first light emitting block and controls the driving voltage on or off; and a control module that turns on or off the first power switch such that a constant current is supplied to the first light emitting block and controls an on/off of the plurality of light emitting modules based on a dimming signal. The control module, in response to a ripple value of the constant current being different from a certain ripple value, changes at least one of a turn-on period and a turn-off period of the first power switch to calibrate the ripple value of the constant current to the certain ripple value.

    Abstract: According to an embodiment of the present disclosure, since the electronic components are fixed on the PCB by the clamp, post processing, such as soldering or application of an adhesive, may be not needed. Also, since the PCB can be spaced from the adjacent configurations by the clamp, the efficient layout of the PCB is possible, resulting in an improvement of productivity of the PCB. In accordance with an aspect of the present disclosure, there is provided a clamp comprises a fixing part configured to surround at least one part of the outer surface of an electronic component, a connection part extending from the fixing part, and penetrating a Printed Circuit Board (PCB), an interference part provided in at least one of the fixing part or the connection part, and configured to be interfered by the PCB and a spacing part protruding from at least one of the connection part or the fixing part.
