产品特点:
产品特点及优势为体积小、耗电小、发热小、寿命长、响应速度快、安全低电压、耐候性好、方向性好等优点。
1.使用寿命:大功率led路灯使用寿命高达50,000小时以上
2.节能:比高压钠灯节电80%以上
3.绿色环保。大功率led路灯不含铅、汞等污染元素,对环境没有任何污染
4.安全:耐冲击,抗震力强,led发的光在可见光范围内,无紫外线(uv)和红外(ir)辐射。无灯丝和玻璃外壳,没有传统灯管碎裂的问题,对人体无伤害、无辐射;
5.无高压,不吸灰尘。消除了普通路灯因高压吸收灰尘导致灯罩发黑引起的亮度降低;
6.无高温,灯罩不会老化发黄。消除了普通路灯因高温烘烤灯罩使其老化发黄引起的亮度降低和寿命的缩短;
7.启动无延时。led在纳秒级,通电即达正常亮度,无须等待,消除了传统led路灯长时间的启动过程;
8.无频闪。纯直流工作,消除了传统路灯频闪引起的视觉疲劳;
9.无不良眩光。消除普通大功率led路灯的不良眩光所引起的刺眼、视觉疲劳与视线干扰,提高驾驶的安全性,减少交通事故的发生。
应用领域:
交通信号灯、背光灯、手电筒、头灯、路灯、矿工灯、led显示屏、射灯、汽车照明、投光灯、城市亮化工程、生活照明、装饰照明、娱乐设施照明、风景设施照明等方面。
