An AC two-wire LED high voltage lamp string with synchronous dimming and color adjustment comprises a high voltage controller and a lamp string group, wherein the high voltage controller comprises a control box, and a first power supply module, a switch control circuit and a first microcontrol unit which are arranged in the control box and connected in sequence; the first power supply module is connected with the switch control circuit and the first microcontrol unit; a second microcontrol unit. The present invention modulates and encodes a high voltage sine wave using the switch control circuit at the controller end and demodulates the sine wave at a bulb end to realize the functions of color change timing, flashing, timing and light control of lamp strings. The lamp strings can be used individually or connected in series and in parallel for use, to satisfy different needs of consumers.

A high voltage control box with light sensing and timing functions is formed by matching an upper cover and a bottom plate; the upper cover is provided with a rocker switch, a light guide column and a knob; a button switch and a knob switch are arranged in the high voltage control box; the button switch is matched with the rocker switch; the knob switch is matched with the knob; a circuit board is arranged in the high voltage control box; and the button switch and the knob switch are arranged on the circuit board. The high voltage control box with light sensing and timing functions in the present invention controls the switch of the bulbs and the switch time through light sensing and timing of the plurality of lamp strings, enhances intelligence of the lamp strings without manual control, and enhances the market competitiveness of products while saving power.

A refrigerator includes a cabinet forming a storage space, a main door that opens and closes the storage space while defining an opening part that is in communication with the storage space, a sub-door mounted to the main door and configured to open and close the opening part, the sub-door including a panel assembly for allowing selective viewing of an inside of the opening part, the injection port is provided at a lower side of the sub-door to direct an insulating foaming solution to a space in the sub-door, a detection device for detecting an operation of a user, a lighting unit inside the refrigerator that turns on based on user operation to allow selective viewing of the inner side of the opening part, and a display unit inside the refrigerator at a position corresponding to the panel.

An electronic device is configured to determine apart (161) of a light effect for a first period and determine a succeeding part (186) of the light effect for a second period succeeding the first period. The electronic device is further configured to determine a likelihood that a second original light command specifying a part (162) of a light effect for the second period will not arrive at its destination and transmit an original first light command or determine and transmit an alternative first light command in dependence on the likelihood and/or the determined succeeding part of the light effect. The original first light command specifies the part of the light effect and the alternative first light command is determined based on the part and the succeeding part of the light effect and specifies a portion of the light effect for both the first period and the second period.
