Abstract

DC60 (29/07/47) Electronic device remote controller with special backlit keypad in which the electronic device remote controller, including the instrument cover, circuit board and panel light pipe - riot. At least one light-emitting diode (LED) that is surface mounted. The special keypad has a base which is perfectly placed. Directly close to the upper surface of the circuit board. The base has a large number of buttons that extend from the circuit board. And at least one channel corresponding to at least one surface-mounted LED. The light pipe has an opening at Corresponding to the keys of the special key panel The light pipes are placed on the special keypads in such a way that the expansion keys pass. Openings in that special key panel So that the light is diffused through the light tube to the button Cover the machine including A top cover with a large number of holes to match the buttons. The divider extends from the inner surface of the cover. Above to touch the light pipe and the base of the special keypad. The divider is arranged to accept the keys that are in between the divider, the electronic device remote controller with a special backlit keypad where the electronic device remote controller, including the panel cover. Circuits and Strobe Light Tubes have at least one surface-mounted light emitting diode (LED). The special keypad has a base which is perfectly placed. Directly close to the upper surface of the circuit board. The base has a large number of buttons that extend from the circuit board. And at least one channel corresponding to at least one surface-mounted LED. The light pipe has an opening at Corresponding to the keys of the special key panel The light pipes are placed on the special keypads in such a way that the expansion keys pass. Openings in that special key panel So that the light is diffused through the light pipe to the buttons, as well as the top cover with a number of holes corresponding to the buttons. The divider extends from the inner surface of the cover. Above to touch the light pipe and the base of the special keypad. The divider is arranged to get the buttons between them.
