Embodiment Construction

[0021] specific implementation plan

[0022] figure 1 , 2 3 and 3 show three kinds of solar fins with different shapes. The fins 1 protrude from the side of the heat conduction column 2. The heat conduction column 2 shown in the figure is solid or hollow. Using the aluminum extrusion method, the profile can be manufactured, and it can be cut to make a sun fancy heat sink. The manufacturing cost is low, and because of the high ribbing efficiency (material saving) and low internal thermal resistance, it is LED. Cooling first choice.

[0023] Figure 4 In the present invention shown, the heat conduction column 2 is solid, and the LED light source 3 is arranged on the front end surface of the heat conduction column 2. Through the contact heat transfer with the end surface, the heat of the LED light source 3 is transferred to the heat conduction column 2, and then transferred to the heat conduction column 2 by the fins 1. into the air. In the figure, rib 1 is divided into thre...

Abstract

The present invention discloses a solid state lamp, comprising an LED light source and a heat sink, the LED light source is provided in the distal end of the heat conducting column, wherein the heat sink uses a sunflower structure with ribs projecting from the side of the heat conducting column, mainly characterized in that the ribs are opened with airflow grooves perpendicular to the axis and penetrating through the circumferential ring, wherein the depth of the deepest airflow groove is greater than half the rib length, the airflow groove has a width of not less than 2mm, and the average height of the short rib is less than five times the average rib gap; the averaged rib length on the heat sink is greater than10mm. The present invention solves the problems of poor air circulation and serious deterioration in heat dissipation efficiency when the heat sink axis level is transversely placed. The present invention also discloses an LED bulb having optimal structure size and the new structure to enable efficacies of lower cost and higher cooling effect.

Description

technical field [0001] The invention belongs to the technical field of LED lighting, and in particular relates to an LED lighting lamp adopting a solar fancy cooling fin. technical background [0002] Due to the advantages of energy saving and environmental protection, LED is considered to be the next generation lighting technology for human beings. However, due to the high cost and low reliability, the popularization and application of LED lighting is hindered. The main reason for the high price and unreliability is the LED heat dissipation problem. [0003] The heat dissipation temperature of LED is not high, below 100°C, so its heat dissipation mainly depends on convection heat transfer, and the proportion of radiation heat transfer is very small. In the process of convective heat transfer, the heat is finally taken away by air flow, so it is very important to ensure smooth air flow, especially natural convection heat transfer (the heat dissipation method used by LED la...
