技术领域technical field

本发明涉及LED路灯，尤其涉及一种组合式LED路灯。The invention relates to an LED street lamp, in particular to a combined LED street lamp.

背景技术Background technique

LED路灯不仅具有色度好、免维护、寿命长的特点，更重要的是比传统路灯更节能。LED路灯代替传统路灯，是公用事业的一场革命。目前大功率LED路灯处于试验或试制阶段，许多国际照明业巨头也纷纷涉足大功率LED路灯，但几乎没有正式应用。试验者或试用者多采用类似普通路灯的灯体，配合风扇散热。风扇散热不仅效果不稳定，且风扇的寿命低、耗能、需要经常维护。传统的路灯其结构不论五金冲压，还是压铸成形的灯体，每种外型规格的产品，均需专用的模具来加工，无形中增加制造成本，限制了大功率LED路灯的推广和应用。LED street lights not only have the characteristics of good chroma, maintenance-free, and long life, but more importantly, they are more energy-efficient than traditional street lights. LED street lamps replace traditional street lamps, which is a revolution in public utilities. At present, high-power LED street lamps are in the test or trial production stage, and many international lighting industry giants have also set foot in high-power LED street lamps, but there are almost no formal applications. Experimenters or trial users often use lamp bodies similar to ordinary street lamps, and cooperate with fans to dissipate heat. The heat dissipation effect of the fan is not only unstable, but also the life of the fan is low, consumes energy, and requires frequent maintenance. The structure of traditional street lamps, whether metal stamping or die-casting, requires a special mold for processing each shape and specification of the product, which increases manufacturing costs virtually and limits the promotion and application of high-power LED street lamps.
