JPH01162457A - Two-color led lighting-up control system for telephone set - Google Patents

Abstract

PURPOSE:To clearly discriminate the condition of a telephone set by light-emitting and coloring the intermediate color of LED two colors with the same luminance as the time of lighting up a single color and using three colors for the condition displaying. CONSTITUTION:When a dynamic lighting-up is activated, at a control circuit to light up dynamically an LED, it is discriminated whether or not an intermediate color is made to light up. When the lighting-up is not executed, the control of a next LED2 is shifted. When the intermediate color is made to light up, it is determined by a flag whether an A color is made to light up or a B color is made to light up with the period of the dynamic light-up. At the time of the A color, D1 is set and at the time of the B color, D2 is set. After the processing is executed up to LED2-LEDP, a flag to determine which of the A color and the B color is made to light up with the period is inverted, and the processing to light up the intermediate color is completed. By executing the processing for a dynamic lighting-up period, the A color and the B color are made light up and control alternately as shown in the figure. Thus, with the average current equal to the average current at the time of lighting up a single color, respective intermediate colors can be made to light up with the same luminance as the time of an A or B single color.

態を表示するように構成されている。The two-color LED display section of the incoming call button flashes in green when the user holds the handset, and lights up in red when the handset of another telephone is held. When the user presses the hold button during a call, the green flashing cycle on the display section of the 1-incoming call button changes, and the hold state is displayed according to the 8-period fluctuation.

（発明が鱗決しようとする問題点） したがって、緑色の点滅の周期の相違だけでは今、通話
中状態か、保留状態か全判別することは困難な場合が多
い。(Problems to be solved by the invention) Therefore, it is often difficult to completely determine whether the call is currently in a busy state or on hold based only on the difference in the cycle of green flashing.

た２色ＬＥＤ点灯制御方式全提供することにある。Is the purpose of the present invention the above-mentioned drawbacks? In this case, the LBD will emit two intermediate colors at the same brightness as when the single color is turned on, and three colors will be used to display the status of the filling machine, including the two single colors and the intermediate color. Our goal is to provide a full range of two-color LED lighting control methods.

前記Ａ色。(Means for Solving the Problems) In order to achieve the above object, two-color L of the telephone according to the present invention is provided.
The ED lighting control method is an LED matrix lighting control method for a telephone that has two color LEDs, A and B, as a display, and the A color is controlled by a control circuit that dynamically lights the LEDi.
