NOVELTY - The utility model claims a traffic signal lamp used graphite radiating fin, comprising provided with floor on the lamp pole, fixed on lamp box of lamp rod upper end is equipped with luminous component in the lamp box, the light sending module comprises lamp shade, LED light source and heat abstractor foundation bed, the heat abstractor is installed on the back substrate in lamp box at the back, the LED light source is set with heat abstractor of foundation bed, the foundation bed heat abstractor comprises one heat abstractor block graphene, the graphene heat abstractor block by several mutually cross is set with heat abstractor piece composed of graphene. Beneficial effect of the utility model is using graphene wherein heat radiating technology, not only greatly increasing heat abstractor property of signal lamp and prolongs the using life of single lamp, but also simplifying signal lamp and installation, convenient production and after selling maintain.
