Abstract: The present invention provides a control method of a receiver. The control method includes the steps of: when the receiver enters a sleep/standby mode, continually detecting an auxiliary signal from an auxiliary channel to generate a detection result; and if the detection result indicates that the auxiliary signal has a preamble or a specific pattern, generating a wake-up control signal to wake up the receiver before successfully receiving the auxiliary signal having a wake-up command.

Abstract: An LED chip package having a topographical glass coating on top surface for enhancing heat dissipation is disclosed. A circular wall is optionally built to surround the LED chip for reflecting light beams from the LED chips; the glass coating further extends to cove the inner wall surface of the circular wall. The larger area the glass coating covers, the more heat the package dissipates in a time unit. The LED chip package according to the present invention exhibits higher thermal dissipation and helps to last longer the life of the LED chip package than a traditional one.
