To provide a radio clock repeater that can be attached in position by a single hand without losing components.SOLUTION: A radio clock repeater comprises: a slave unit body 21 that outputs a pseudo-standard radio wave; a slave unit casing 12 in which the slave unit body 21 is housed; a fastener 13 which is provided at the slave unit casing 12 and fastens the slave unit casing 12 to a wall surface fixture F; and a fixture 16D for fixing a radio clock C to the front of the slave unit casing 12. The fastener 13 includes a plate body 14 formed with a wall-hanging hole 14A into which a tip Ft of the wall surface fixture F is inserted, and a lock member 15 which is located below the wall-handing hole 14A and prevents the tip Ft from coming off. The lock member 15 includes a leaf spring member 15A fixed to the plate body 14, and a non-fixing part 15B attached to the leaf spring member 15A and capable of coming close to or separating from the wall-handling hole 14A. The non-fixing part 15B is biased to be in a state of being close to the wall-hanging hole 14A.SELECTED DRAWING: Figure 7

This product is a slave unit of a radio-controlled clock repeater consisting of a master unit and a slave unit that transmit and receive time information signals according to standard time so that the time of the radio-controlled clock can be automatically corrected, and receives the time information signal and outputs a pseudo standard radio wave, enabling the time of the radio-controlled clock to be automatically corrected. This product is used while placed on a table or the like.

To provide a radio-controlled clock repeater that can prevent an error when acquiring time information on the basis of the voltage waveform of a commercial AC power supply.SOLUTION: A host machine 1 comprises a host machine RTC 3 that counts time, and a host machine controller 8 that is connected with the host machine RTC 3. The host machine controller 8 calculates a count value A0 that is the difference between a first time value measured on the basis of the periodicity of a voltage waveform from a commercial AC power supply for every predetermined time T0 and a second time value measured by using the host machine RTC 3, calculates the average value of the plurality of count values A0 as a reference count value A1, corrects the time counted by the host machine RTC 3 so as to reduce a difference value A2 that is the difference between the count values A0 and the reference count value A1, and generates a time information signal on the basis of the time counted by the host machine RTC 3.SELECTED DRAWING: Figure 10

The application discloses a circadian rhythm lighting controller based on a radio clock, an LED driving module and a lighting system with the same, and the lighting controller comprises a radio clock module receiving time coding information in the form of low-frequency radio waves, a storage device storing lighting parameters related to the time information, an MCU module and a dimming controller; the MCU module receives a timing signal sent by the radio clock module and decodes the current time information; the storage device is accessed to find the lighting parameters matched with the current time; then the lighting instructions are obtained or converted; the dimming controller generates corresponding control signals according to the lighting instructions and sends the control signals to the driving circuit of the lighting load. The radio clock module directly receives the standard time coding signal emitted by the national time service station, and the time error can be controlled within milliseconds, so that an absolute accurate and never-drifting time source is provided for the circadian rhythm lighting.
