A good cooling, and made fine LED solar lighting, in fact, heat and power is a corresponding relationship. The volume of the heat sink determines the heat storage capacity, so the heat sink is generally a large lump. The area of the heat sink determines the final distribution capacity, in order to increase the area, the general will be made of various columns, net, film and other shapes.
Radiator in the cost of LED solar lamps accounted for a large piece. Some factories cut corners in order to save costs, will be shoddy, small and big. Then the question came: how do we judge a LED solar lighting radiator do well?
Of course, the most direct way is to measure the temperature of the LED chip when the LED solar lamp is working, the term is called "knot temperature". How he blows, knot temperature control in the acceptable range, that is done well, and vice versa is cut corners.
