LED road lamp module with plastic cooler and manufacture method thereof

Abstract

The invention relates to the technical field of lighting equipment, in particular to an LED road lamp module with a plastic cooler and a manufacture method thereof. The LED road lamp module comprisesa lens and a plastic cooler. In the LED road lamp module with the plastic cooler and the manufacture method thereof, heat is produced by an LED bulb on a lamp panel, the bulb emits light and at the same time produces the heat, the temperature of the lamp panel is raised, an aluminum base plate on the back of the lamp panel is in contact with liquid in the plastic cooler, the heat is transferred into the liquid, dynamic circulating liquid heat convection is formed in the plastic cooler, the heat is uniformly and rapidly dispersed onto the surface of the plastic cooler, and a cooling process isfinished after heat exchange is carried out with surrounding air. The LED road lamp module has the advantages that although a difference between the temperature of the bulb and the surface temperatureof the cooler is small, a difference between the surface of the cooler and the temperature of the surrounding air is large, the heat radiation capability of plastics is great, and therefore, the whole cooling effect is great; and the material cost of the plastic cooler is low, the following processing procedures are few, the production efficiency is high, a cooling system is simple and easy, andthe popularization property is strong.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to a plastic radiator LED street lamp module and a manufacturing method thereof. Background technique [0002] The current radiators are mostly made of aluminum alloy, which has good thermal conductivity, but the cost of materials is high, the follow-up processing steps are many, and the production efficiency is low. There are also radiators made of carbon-plastic synthetic material injection molding as a whole, although The cost is low, but the thermal conductivity of carbon-plastic composite materials is not good, so the overall heat dissipation performance cannot reach the effect of aluminum alloy radiators. At the same time, some water-cooled radiators need external pipes and water pumps to pump water to the outside of the module and then the blades. heat dissipation, but the system is more complex. In view of this, we propose a plastic radiator LED street lamp modul...
