Description

一种近全方位出光的 LED灯 技术领域
本发明涉及 LED照明设备， 尤其涉及一种灯近全方位出光的 LED片式光源和由此 构造的 LED整灯。
背景技术
由于发光二极管为一种可将电能转换为光能的高效率冷光发光元件， 并具有耗电量 低、 寿命长等优点， 故在照明领域中使用 LED灯进行照明已经成为趋势。
LED灯芯的寿命与 PN结结点的工作温度有较密切的联系， 目前 LED灯在工作过程 中只有大约 50%的电能转换成光能， 其余的电能几乎都转成热能， 使 LED灯的温度升 高， 而温度每增加 10摄氏度其信赖性就会减少一半。 特别在大功率 LED灯中， 散热是 个大问题。如果散热不好会直接导致 LED灯芯快速老化，稳定性降低， 同时散热不好会 产生严重光衰影响灯的寿命。
由于封装好的 LED灯珠是定向发光， 其发光形式与传统光源全方位的发光模式不 同。 在许多应用情况不合适， 需要通过配光或者二次光学方法才能达到光源的使用目 的。
