Benefits of technology

This technology described in this patents allows for better cooling performance when created with different materials like ceramic material (Al2O3), metal foil). Additionally, it improves the brightness and lifespan of LED lights compared to traditional methods such as filament bulbs used today due to its longer use time without losing power overtime. Overall, these technical improvements improve the overall functionality and longevity of LED products while reducing their size and weight.

Problems solved by technology

This patented describes two technical solutions aimed towards improving the cooling properties of LED lights without compromising their effectiveness or lifetimes over longer periods due to excessively large heat generation caused by the use of metallic material used during manufacturing processes.

Abstract

The invention discloses a light emitting diode (LED) lighting device having an excellent radiating function, which comprises an aluminium substrate (1) and a plurality of LED chips (2), wherein the aluminium substrate (1) is provided with a line layer and a plurality of circular arc-shaped grooves (3); the LED chips (2) are packaged in the circular arc-shaped grooves (3); LED chip welding spots (4) connected with the line layer electrically are arranged on both sides of each circular arc-shaped groove (3) of the aluminium substrate (1); and the LED chip welding spots (4) are connected with the two poles of each LED chip (2) electrically through leads. In the LED lighting device having the excellent radiating function, the LED chips are packaged in the aluminium substrate to form a solidified body of LEDs and the aluminium substrate, so that a step of radiation is reduced. An LED lamp packaged by the LED lighting device having the excellent radiating function has a good radiating effect, can reduce the working temperature of the LED chips effectively and can have good effects of improving the light efficiency of the LEDs and prolonging the service life of the LEDs.
