What aspects should we start from when choosing a floodlight?

The design of the structure is related to the function of the whole product indicators, including whether the heat dissipation structure is fair, the heat dissipation of the LED light has been the most headache of the manufacturers, the quality of the heat dissipation of the lamps is the primary problem that directly affects the size of the light decay, the basic way of the lamp shell heat dissipation technology and heat transfer is: Conduction, convection and radiation, thermal treatment also starts from these three aspects, divided into transient analysis and steady state analysis. The main transmission way of the radiator is conduction and convection heat dissipation, and the natural radiation heat dissipation can not be ignored. If the heat energy can not be effectively eliminated, it will lead to very serious consequences.

Temperature will reduce LED luminous flux and luminous efficiency, cause light wave redshift, color, but also cause device aging and other adverse phenomena, the most important is to make the LED life is exponentially reduced, because the LED light decay or life is directly related to its junction temperature, heat dissipation is not good junction temperature, life is short, According to Arenius' rule, every 10 ° C decrease in temperature doubles the lifespan. And now the market situation of the LED floodlight housing almost violates the principle of LED heat dissipation, against the will to be modified, set mold, etc., not only the overall aluminum of the housing is insufficient, but also in the radiator is jersey-cutting, shoddy! The thickness of the original radiator and the cooling teeth thin, shorten, through the full wattage with the power test, the modified thin shell surface temperature has reached more than 90 degrees, how can such a lamp shell ensure the service life of the lamp? How to improve the quality of LED lights!

Secondly, we should consider the structural problems of the installation of the lamp, whether the bracket has enough support, whether the screw can be locked, if the wind is firm when installed at high altitude, and whether the structure meets the IP65 waterproof requirements can not be ignored, waterproof is the hub, once the water will die the lamp, many companies do not have waterproof verification equipment to support, It's very risky to light up and ship.
