5060 multi-color LED is a compact flat head high-power light source. The total luminous area of four single control chips is 2.1 * 2.1mm. The vertical structure chip is packaged with ultra-thin glass, and the luminous area is close to the package surface. Ceramic thermoelectric separation structure is adopted, and aluminum nitride substrate is used for heat dissipation. OSRAM has products with current of 1a and 2.5A.
5050 multi-color LED is a compact high-power light source with convex head. The total luminous area of four single control chips is 2.1 * 2.1mm. The vertical structure chip is added with concentrated silica gel, so the light collection efficiency is higher. Ceramic thermoelectric separation structure and aluminum nitride substrate are used for heat dissipation. Cree has a current 1A product.
Bat airfoil polychrome LED is an early four in one package, also known as analog lumen package. The total luminous area of four single control chips is 2.5 * 2.5mm, made of red copper. Common products are products with monochromatic current of 500mA.
The surface of 5060 multi-color LED is flat, which is mainly used in the zoom optical system with light guide rod. The positive and negative levels of each color are on the same side, so it is more convenient to connect when making the scheme of single point and single control.
5050 polychrome and bat airfoil polychrome are the two mainstream products applied to the fixed Joppa lamp. Next, we compare the light efficiency output of the two light sources:
The power of red light is generally lower than that of other colors, because the voltage of red light chip is low. When the lamp adopts bat wing four colors, the total power of a single lamp bead should be * about 8W. When 5050 four colors are adopted, the total power of a single lamp bead can be as high as 12W. The 5050 four-color chips are arranged more closely, the mixing efficiency is higher, and it is easier to design small angle optical mirrors. The 5050 four-color adopts the bracket of thermoelectric separation, which has higher heat dissipation efficiency.
