Heat dissipater for LED lamp

The invention creates a heat dissipater for an LED lamp and belongs to the technical field of LED illumination. The heat dissipater comprises a heat-dissipating plate and heat-dissipating holes, wherein the heat-dissipating plate is of a cuboid structure; the heat-dissipating through holes are formed in the heat-dissipating plate; the heat-dissipating through holes are formed in the heat-dissipating plate in net shape; the heat-dissipating through holes are of structures wide at two ends and narrow in the middle. Air convection is increased by means of the bee net heat-dissipating through holes in the heat-dissipating plate, so that heat is diffused to air. By adopting the structure, the temperature reduced by the heat dissipater of same size of same lamp is greater while the conventionalmaterial is not changed, so that the service life of the lamp is prolonged, and the performance of the lamp is improved. 本发明创造提供种LED灯具散热器，属于LED照明技术领域，包括散热板及散热透孔，所述的散热板是长方体结构，所述的散热板上设置有散热透孔，所述的散热透孔在散热板上呈网状布置，所述的散热透孔采用两端宽，中间窄的结
