The utility model discloses an LED flat lamp, which comprises an aluminum frame, an inner ring of the aluminum frame is provided with a recess, a light source plate is arranged on the bottom of the recess cavity, a light source plate is connected with an external non-isolated driving power source, and a diffuser plate, a light guide plate and a reflective paper are arranged on the cavity mouth of the recess cavity in succession, and a light source plate is arranged. The LED particles are facing the side wall of the light guide plate. The light emitted by the LED particles of the light source plate is introduced from the side wall of the light guide plate. A plastic-coated aluminum bracket or an aluminum-coated plastic bracket is arranged between the circuit board of the light source plate and the bottom of the cavity containing the concave cavity. The advantage is that the circuit board of the light source plate, i.e. the light source plate, is electrically provided with a plastic-coated aluminum bracket or an aluminum The part is separated from the aluminum frame by a large margin, thus effectively increasing the creepage distance between the light source plate and the aluminum frame, so even if the LED flat lamp fails, it can also avoid the risk of electric shock.
【技术实现步骤摘要】
一种LED平板灯
本技术涉及一种LED灯具,尤其是涉及一种LED平板灯。
技术介绍
现阶段,LED平板灯通常采用两种驱动方案,多数采用隔离驱动方案,少数采用非隔离驱动方案。两种驱动方案各有优缺点:隔离驱动方案的优点为安规容易过、不用考虑爬电距离、光源板的散热效果好,缺点为驱动的价格比较贵、驱动的体积较大;非隔离驱动方案的优点为驱动的价格比较便宜、驱动的体积较小、驱动壳的价格也比较便宜,缺点为安规很难解决、爬电距离不够、光源板的散热效果不好。业内考虑成本时自然选择采用非隔离驱动方案,但是采用非隔离驱动方案时,非隔离驱动电源的输出连接部分也就是光源板仍为高压部分,LED平板灯一旦失效,则会因爬电距离不够而产生触电风险,因此需要解决爬电距离不够的问题。
技术实现思路
本技术所要解决的技术问题是提供一种LED平板灯,其采用非隔离驱动电源,且能够满足爬电距离。本技术解决上述技术问题所采用的技术方案为:一种LED平板灯,包括铝框,所述的铝框的内圈四周设置有容纳凹腔,所述的容纳凹腔的腔底上安装有光源板,所述的光源板连接有外置的非隔离驱动电源,所述的容纳凹腔的腔口上卡设有依次叠放的扩 ...
