The invention relates to a sealed warning lamp with an efficient heat dissipation function. A bottom metal profile plate for connecting a plurality of warning lamp units in series is arranged at the bottom of the warning lamp units, a profile plate groove for mounting the bottom metal profile plate is formed in the bottom of a bottom shell of each warning lamp unit, a plurality of lamp bodies are mounted in the bottom shells, each lamp body is provided with a metal radiating tail cover for a lamp panel in the lamp body to be contacted and mounted, each metal radiating tail cover is provided with a heat conduction plate, each bottom shell is provided with a through hole which is right opposite to the corresponding profile plate groove and is shielded by the metal profile plate at the bottom, a protruding cylindrical fence surrounds an opening, located in the bottom shell, of each through hole, a waterproof heat dissipation channel is formed through the cylindrical fences and the through holes, the heat conduction plates penetrate through the waterproof heat dissipation channel and makes heat conduction contact with the bottom metal profile plate, and heat removal gaps enabling the interiors of the bottom shells to be communicated with the exteriors of the bottom shells are formed between the waterproof heat dissipation channel and the heat conduction plates. Due to the design of the heat dissipation structure, the heat dissipation performance of the sealed warning lamp can be effectively improved, and the sealing and waterproofing performances are guaranteed.
本发明涉及一种高效散热的密封型警示灯,警示灯单元底部设有实现多个警示灯单元串连的底部金属型材板,警示灯单元的底壳底部设有供底部金属型材板安装的型材板槽,底壳内安装有若干灯体,灯体具有供灯体内灯板接触贴装的金属散热尾盖,金属散热尾盖设有热量传导板,所述底壳上设有正对型材板槽被底部金属型材板遮挡的贯通孔,且在该贯通孔位于底壳内部的口环绕有凸起的筒状围挡,经筒状围挡及贯通孔形成防水散热通道,热量传导板穿过防水散热通道并与底部金属型材板导热接触,防水散热通道与热量传导板之间具有连通底壳内部和底壳外部的排热间隙。该散热结构设计下能够有效改善密封型警示灯散热性能,且保证密封防水性能。
