Abstract
A miniature night lamp with weathercast and alarm module comprises a miniature night lamp and a control means. In addition to providing night illumination, the control means is able to receive the weathercast signal of the weather bureau and let the user to hear information about the local weather conditions, and should there be any abnormal weather conditions the control means is able to deliver a sound alarm from a speaker.
Claims4
A miniature night lamp with weathercast and alarm module comprising a main body of the miniature night lamp, a power supply and a control means, wherein said power supply supplies electrical power to said main body of the lamp and said controls means after converting an alternating power current into a direct power current;
- said control means further comprising:
- a power allotment unit for receiving the stabilized DC from said power supply and dispensing power to all component circuits included in said control means;
- an antenna for receiving a frequency signal delivered by the weather bureau and transmitting said signal to a high frequency amplifier to amplify, and transmitting said signal to a frequency mixer after being amplified;
- an input unit for receiving a selected channel, and sending the selected result to a multi control unit (MCU);
- said MCU for receiving the signals from said input unit and a frequency converter, and transmitting the analyzed signal to a phase lock loop;
- said phase lock loop for receiving the signal from said MCU and locking a designated oscillation frequency and the reference frequency in same frequency and phase, and transmitting said locked frequency signal to a frequency mixer;
- said frequency mixer for receiving and mixing the frequency signals from a high frequency amplifier and said phase lock loop to obtain a first medium frequency signal, and sending it to a frequency converter;
- said frequency converter for converting said first medium frequency signal into a second medium frequency signal to output to an audio frequency amplifier and said MCU.
- said audio frequency amplifier for amplifying said second medium frequency signal so as to actuate a speaker to broadcast weather conditions;
- wherein,
- said MCU analyzes said second medium frequency signal so as to detect if there be any signals about abnormal weather conditions, if there is, an alarm is actuated to make a sound alarm from said speaker by said audio frequency amplifier.
