Samsung introduced the latest LED module products using secondary optical lenses. In this new LED module product, the way of using only LED package components has been changed, and the design of secondary optical lens (lens) has been increased, like direct backlighting. The design of the LED package component plus the lens effectively reduces the thickness of the lamp and the module, opens the illumination angle, and simultaneously reduces the number of LEDs used.
In terms of size of 250mm*259mm, only 32 LED components are used. Samsung pointed out that this new product aims to replace the traditional T5 and T8 lamps, and adopts medium-power LED components to improve the homogeneity and luminous efficiency of the light source. The use of secondary optical lenses achieves better consistency and contributes to the design of lighter and lighter luminaires.
In 2014, Edison also introduced a new product that introduces the concept of direct-lit backlight into lighting applications. The LED package components are matched with secondary optical lenses to open the illumination angle, and the diffusion plate is used together to make the light source evenly distributed. The design of the light bar module changed the "starry" of the flat lamp and adopted the high-density LED design to achieve the goal of reducing the number of LEDs used, and the number below 50 LEDs reached more than 3000 lumens.
