Description

一种麻将机电源灯智能关闭装置
技术领域
本实用新型涉及麻将机，尤其涉及一种麻将机电源开关智能关闭装置。
背景技术
麻将机桌中心的控制盘上有着若干个用以指示麻将机处于某种状态的指示灯和用于装饰的LED灯。这些灯在麻将机打开后，就一直保持通电照明状态。娱乐者在玩麻将时常常会休息或因其他事而中途停止一段时间，但在上述停止娱乐期间内，一般不会关掉麻将机，因此，控制盘上的灯就会一直亮着，从而白白消耗能源。
发明内容
本实用新型目的在于克服以上现有技术之不足，提供一种根据娱乐者对麻将机有操作间隔，来对电源开关进行控制的麻将机电源灯智能关闭装置，具体有以下技术方案实现：
所述麻将机电源灯智能关闭装置，与电源开关连接，包括中央处理器，LED灯以及三极管，所述三极管的基极与中央处理器的对应端口连接，所述LED的两端分别连接所述三极管的发射极与一正电位Vcc。
所述的麻将机电源灯智能关闭装置的进一步设计在于,所述中央处理器为MA104单片机。
本实用新型的优点如下：
采用单片机控制与三极管间的接口的高低电位，进而控制LED灯的亮灭，该装置结构简单，可靠性高，以较低的成本达到节省能源的效果。
附图说明
图1为所述装置的电路图。
具体实施方式
下面结合附图对本实用新型方案进行详细说明。
对照图1，麻将机电源灯智能关闭装置，与电源开关连接，包括中央处理器，LED灯以及三极管，三极管的基极与中央处理器的对应端口连接，LED的两端分别连接三极管的发射极与一正电位Vcc。本实施例采用的中央处理器为MA104单片机。该单片机中烧录有控制单片机与三极管间接口电平高低的程序，从而使三极管导通或截止，当三极管导通时，LED灯负极接地，从而点亮LED灯，当三极管截止时，LED灯负极为高电平，此时LED灯则熄灭。 

Claims (2)

1.一种麻将机电源灯智能关闭装置，与电源开关连接其特征在于，包括中央处理器，LED灯以及三极管，所述三极管的基极与中央处理器的对应端口连接，所述LED的两端分别连接所述三极管的发射极与一正电位Vcc。
2.根据权利要求1所述的麻将机电源灯智能关闭装置，其特征在于,所述中央处理器为MA104单片机。
