Description

LED bulb lamp ventilation and heat structure

Technical field

The utility model relates to a kind of LED bulb lamp radiator structure, relates in particular to a kind of LED bulb lamp ventilation and heat structure.

Background technology

LED illuminating lamp, due to advantages such as its energy-saving and environmental protection, long-lives, will replace the New Innovational Illumination Lamps and Lanterns of conventional incandescent and be acknowledged as.But LED light fixture has, an outstanding shortcoming---when its work, caloric value is large.If there is no good cooling measure, heating can cause LED light to decline seriously even directly burning out, and therefore existing LED light fixture is generally equipped with heat abstractor.Along with developing by leaps and bounds of LED lighting engineering, to LED illuminating lamp, heat radiation proposes various schemes to people, and what have is even LED assembling radiator fan or reflux radiating conduit, and this has increased the cost of LED light fixture undoubtedly greatly, hinders popularizing of LED light fixture.The mode of utilizing ventilating convection having improves radiating efficiency, the advantage of the radiating mode of ventilating convection is can obtain better radiating effect under the heat sink material of equivalent, but irrational design tends to make convection effects to have a greatly reduced quality, even thinking by mistake the more convection effects of chute of having is better.Therefore need to research and develop a kind of LED bulb lamp ventilation and heat structure of design science.
