Some manufacturers use constant current circuit, compared with straw hat type LED, patch LED heat dissipation is slightly better, there is a heat conduction substrate, with aluminum substrate, can be part of the heat export. However, due to the neglect of LED heat, many medium power patch ED energy-saving lamps, no radiator, still use plastic shell, light decay is still serious. Low-end power supply is used for resistance-capacitance step-down.

A light source and the color of the black body at the same time, the absolute temperature of the black body is called the color temperature of the light source. Because the relative color temperature is actually the evaluation value of the light color performance of the light source when the blackbody radiation approaches the light color of the light source, it is not an accurate color contrast, so the two light sources with the same color temperature may still have some differences in the appearance of the light color. The color temperature alone cannot tell the color rendering ability of the light source to the object, or how well the color of the object is reproduced under the light source.

How the construction of an urban lighting LED system marks the strength and maturity of the city. In the design process of the street LED lighting system, in addition to the basic lighting function design, we must also consider the integrated design of the use of the street LED lighting system, such as energy saving, operation intelligence and maintenance convenience, so the street LED lighting system is a combination of light source materials, energy saving control, communication links.
