Abstract

A lamp includes a lamp body, an LED light source, a storage unit, a switch apparatus, and a microprocessor. The storage unit stores a function table recording a relationship between a plurality of types of touches and a plurality of control functions. The switch apparatus includes a touch panel, a touch controller, and an indicator located under the first touch region. The touch panel generates signals in response to touches applied on thereon. The touch panel includes a first touch region and a second touch region. The touch controller receives the signals and determines the type of the touch intended. The microprocessor refers to the function table, and controls the LED light source to execute the control function and to give visual feedback when the touch panel is touched. A switch apparatus is also provided.

Claims

a storage unit storing a function table recording the relationship between a plurality of types of touches and a plurality of control functions of the lamp, the type of the touches associated with touch manners and the positions of the touches;

a switch apparatus fixed on the lamp body, the switch apparatus comprising;

a touch panel, configured for generating operation signals in response to the touches applied on thereon, the touch panel comprising a first touch region and a second touch region, the first touch region is circular, the second touch region is an annular region surrounding the first touch region;

a touch controller, configured for receiving the operation signals generated by the touch panel, and determining the type of the touch according to the operation signals; and

an indicator located under the first touch region; and

a microprocessor electrically connected to the switch apparatus and configured to switch between the power on and power off states of the LED light source in response to an operation applied on the first touch region, and configured to adjust the brightness of the LED light source in response to a first operation applied on the second touch region, and to adjust the color temperature of the LED light source in response to a second operation applied on the second touch region, according to the function table, and to control the indicator to flash when the touch panel is touched.

2. The lamp as described in claim 1, wherein:

if the touch manner is a tap operation and the touch position is the first touch region, the associated control function is to switch between the power on and power off states of the LED light source;
