Seoul Semiconductor

Seoul Semiconductor is a South Korean LED manufacturer headquartered in Ansan-si. The company built its corporate logo and identity in 1994, using two connected green circles.

Seoul Semiconductor, a South Korean LED manufacturer, uses a corporate logo built from two connected circles in green. The company’s official brand page describes the mark as representing the earth and the universe, with the connection between the two circles symbolizing unity and single-mindedness. The green color is chosen to represent the natural environment. The connection of the two circles is meant to convey a sense of throbbing movement and great ambition, with the company’s small steps of development spreading throughout the world and humanity, just as a stone thrown into a calm lake causes ripples that spread across the entire lake. [1]

Design and History

Seoul Semiconductor was founded in 1987 and is headquartered in Ansan-si, South Korea. [2] The company’s official website lists its year of establishment as 1992, referring to its start with around 30 employees in a small commercial building in Bongchen-dong, Seoul. [3] [4]

According to a company profile, Seoul Semiconductor built its company logo and corporate identity (CI) in 1994, with the stated dream of making their LEDs light up even a space station. [4] The same description appears in a Chinese-language article about the company, which states that in 1994 the company established its current logo and CI. [5]

The current logo is documented on the company’s official brand page, which describes the two-circle design and its green color. [1] The same description appears on the Korean-language version of the brand page. [6]

Meaning and Symbolism

The official brand description provides the documented symbolism for the logo:

  • The smaller circle represents the earth, and the larger circle represents the universe. [1]
  • The connection between the two circles represents the value of unity and single-mindedness. [1]
  • The green color represents the natural environment. [1]
  • The connection of the two circles conveys a sense of throbbing movement and great ambition, with the company’s small development steps proliferating throughout the whole world and humanity. [1]

The same symbolism is echoed on the brand page of Seoul Viosys, a related company, which describes the small circle as the earth, the large circle as the universe, and the connection as representing unity and cooperation. [7]
