CSP is an acronym for Chip Scale Package. Microscale, high-performance LED packages are called CSP LEDs. CSP makes the same power LEDs smaller.

Although LEDs can produce bright lights in a small space, LEDs are getting smaller day by day. The reduction in the size of LEDs has allowed the design of smaller and lighter lighting products. The last point reached by this technology was CSP technology.

There are various sizes of SMD LEDs on the market such as 2835, 3535, 3825 and 5050. For example, the dimensions of an LED in the 3535 package are 3.5×3.5 mm. CSP LEDs, on the other hand, can be produced in a very small size of 1.1×1.1 mm.

The CSP LED is the equivalent size of an LED chip or a maximum of 20 percent larger.

CSP LEDs have high light intensity. In this way, despite its small size, it can produce light with high performance. Thanks to its wide light angle, it offers a more homogeneous lighting performance.

CSP LEDs do not contain wires like ordinary SMD LEDs. While this makes them a more stable product, it also lowers their costs. Its thermal performance is also better than ordinary LEDs.

CSP LEDs are frequently used in vehicle headlights and headlight bulbs (LED headlight bulbs) in the automotive industry.

Vehicle headlights need high light output but have little room for LED placement. The small area also complicates the cooling process. CSP LEDs are qualified to meet this need. In addition; The continuous vibration of the LEDs on the vehicle caused the LEDs to malfunction. However, CSP LEDs offer a longer lifespan as they do not contain wire connections like SMD LEDs.

Emre Yılmaz, the founder of Lighting Portal, graduated from Atılım University Department of Electrical and Electronics Engineering in 2013, and since then has been involved in the management and product development activities of state-supported projects in the lighting industry. He completed his master's degree at Gazi University Industrial Design Engineering Department and continues his education in the doctorate program of the same department.
