광원 및 점탄성 도광체를 갖는 광학 장치가 본 명세서에 개시된다. 광원으로부터의 광은 점탄성 도광체로 들어가고 내부 전반사에 의해서 도광체 내에서 전송된다. 점탄성 도광체는 감압 접착제를 포함할 수 있다. 광학 장치는 다양한 구조물에 사용될 수 있으며, 여기서 광학 장치는 점탄성 도광체 내에서 전송되는 광을 발광한다. 구조물에는 표지(sign), 마킹(marking), 조명 장치, 디스플레이 장치, 키패드 조립체 및 차량용 미등 조립체에 사용되는 것들이 포함된다. Disclosed herein is an optical device having a light source and a viscoelastic lightguide. Light from the light source enters the viscoelastic lightguide and is transported within the lightguide by total internal reflection. The viscoelastic lightguide may comprise a pressure sensitive adhesive. The optical device may be used in a variety of constructions wherein the device emits light being transported within the viscoelastic lightguide. Constructions include those used for signs, markings, illumination devices, display devices, keypad assemblies and tail light assemblies for vehicles.
