The utility model relates to a LED explosion-proof lamp, including an explosion-proof lamp housing and an explosion-proof lamp cover connected to the bottom of a explosion-proof lamp shell. The explosion-proof shell body is divided into a cooling cavity and a power supply cavity from the bottom to the top. The power supply cavity is located above the radiator cavity. The heat dissipation chamber includes a air duct cavity and a heat collecting chamber. Several air channels which are connected to the bottom of the heat collecting chamber are arranged at the bottom of the air duct cavity in turn, and the explosion proof cover is arranged on the outside of the explosion-proof plate. The explosion protection cover is fixed with the flanges between the explosion-proof cover and the explosion-proof plate. The explosion-proof plate is provided with a hot hole connected with the air duct cavity, and both sides of the hot passage holes are arranged on both sides of the heat pass hole. The utility structure is simple, the heat passes through the air duct of the air duct to the collector cavity, and through the heat dissipation strip around the outer wall of the heat collector, the explosion proof plate can avoid the damage to the builders after the explosion of the explosion-proof lamp in the special case, and the heat dissipation effect is better and the safety coefficient is higher.

一种LED防爆灯
本技术涉及LED照明
,具体来说是涉及一种LED防爆灯。
技术介绍
LED防爆灯是防爆灯的一种,其原理同防爆灯相同,只不过光源是LED光源,是指为了防止点燃周围爆炸性混合物如爆炸性气体环境、爆炸性粉尘环境、瓦斯气体等而采取的各种特定措施的灯具。LED防爆灯在长时间使用过程中外壳表面会积攒大量灰尘,不及时清洗会导致热量排出不及时,具有一定的安全隐患;现有的LED防爆灯排热局限性较窄,在特定的工作场合,如矿井、粉尘车间等空气对流相对较差的环境下散热效果较差、安全系数较低。
技术实现思路
本技术的目的是为了解决上述所存在的缺陷,提供一种散热效果好、安全系数更高的LED防爆灯。为实现上述目的,本技术的技术方案如下:一种LED防爆灯,包括防爆灯壳体以及与防爆灯壳体底部连接的防爆灯灯罩,其特征在于:所述防爆灯壳体由下而上分为散热腔和电源腔,所述电源腔设在散热腔的上方,所述散热腔包括风道腔和集热腔,在所述风道腔内设有若干个与集热腔底部贯通的风道,所述风道腔的底部依次设有防爆板和LED灯板,所述防爆板的外侧四周罩设防爆罩,所述防爆罩与防爆板之间通过法兰固定,所述防爆板上设有与风道腔连通的热通孔,在所述热通孔的两侧均设有防爆片。作为优选的技术方案,还包括散热条,所述散热条设在集热腔的外侧四周,所述散热条的数量至少为4根。作为优选的技术方案,还包括防爆罩密封圈,所述防爆罩密封圈设在防爆罩与防爆板的连接端。本技术的有益效果为:结构简单、热量经风道腔内的风道传至集热腔内,通过集热腔外壁面四周的散热条进行集中散热,同时,防爆板可避免特殊情况下防爆灯爆裂后造成对施工人 ...
