发明内容
本发明的目的在于克服上述技术不足，提供一种不设变压器驱动电路，环境因素影响低，可靠性高，无光损失，无污染，无热引起效率降低的无变压器驱动电路LED灯泡。
本实用新型解决技术问题所采用的的技术方案是：一种无变压器驱动电路LED灯泡，包括插头和灯泡，共特征在于灯泡的一端与可变电阻和电阻一端连接，可变电阻和电阻的另一端与插头连接；灯泡的另一端与电阻的一端连接，电阻的另一端与插头连接。
本实用新型的有益效果是：该实用新型无变压器，无需AC/DC变压器驱动电路，环境因素影响低，可靠性高；无变压器的光效损失；无污染，无热引起的效率降低；节省材料，成本低，节能效果好，寿命长。
附图说明
以下结合附图以实施例具体说明。
图是无变压器驱动电路LED灯炮的电器原理图。
图中：J1-插头；AC/LED-灯泡；PTC-可变电阻；R1、R2、R3-电阻。
具体实施方式
实施例，参照附图，一种无变压器驱动电路LED灯泡，包括插头J1和灯泡AC/LED，共特征在于灯泡AC/LED的一端与可变电阻PTC和电阻R1一端连接，可变电阻PTC和电阻R1的另一端与插头J1的2端连接；灯泡AC/LED的另一端与电阻R2、R3的一端连接，电阻R2、R3的另一端与插头J1的2端连接。插头J1插在AC220V电源上。
