LINEAR TUBE TYPE LED LIGHT FIXTURE

WIPO Patent Application WO/2018/146781

A1

[Problem] To increase the light being irradiated in the front direction via a simple and low-cost constitution and provide a linear tube type LED light fixture capable of concentrating light energy. [Solution] This linear tube type LED light fixture comprises: metal cap parts (160) at both ends, which are mountable in the sockets of a linear tube type fluorescent light; a linear tube member (110) extending between the metal cap parts (160); a reflective plate (120); an electronic base board (130); an LED line light source (140) having many LED chips aligned on the electronic base board (130); and an electronic control circuit (150) controlling the supply of power to the LED line light source (140). The linear tube member (110) comprises a light-permeable cover (111) and a main body base portion (112). The base end side of each of the reflective plates (120) is attached to the light-permeable cover (111). The forward end side of each of the reflective plates (120) extends to the vicinity of the LED line light source (140) on the electronic base board (130). The reflective plate (120) is positioned so as to open into a V-shape from the vicinity of the LED line light source (140) to both sides thereof. The light irradiating from the LED element (141) to the periphery thereof is reflected by the reflective plate (120), which increases the amount of light in the front direction.
