Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiment shown below is an illustration of the structure for actualizing the technical thought of this invention, and does not limit this invention. In addition, in the following description, the same name and the same code|symbol represent the same or the same component, and detailed description is omitted suitably.

[0030] In the LED module 100 of this embodiment, as figure 1 As shown, a plurality of LED devices 10 are arranged adjacent to each other on the substrate 20 . Furthermore, each of the plurality of LED devices 10 has a light emitting diode element 11 , and a reflective member 12 is arranged on the side of the light emitting diode element 11 . Furthermore, a first translucent member 13 is arranged above each light emitting diode element 11 . Here, the first translucent member 13 contains phosphors. Also, among these plurality of LED devices...

Abstract

An LED module includes a mounting board and LED devices. The LED devices include at least one first LED device and second LED devices each including a light emitting diode element, a reflective memberdisposed lateral to the light emitting diode element, and a light transmissive member disposed above the light emitting diode element. The first LED device includes a reflective member on all lateralfaces of the light transmissive member, and its upper face serves as a light extraction face. The second LED devices each includes the reflective member covering all of the lateral faces of the lighttransmissive member facing the at least one of the LED devices so that all of the lateral faces of the light transmissive members not facing any one of the LED devices and an upper face of a corresponding one of the second LED devices serve as light extraction faces.

Description

technical field [0001] The present invention relates to LED modules. Background technique [0002] There is known an LED module in which a plurality of light emitting diode (LED) devices are arranged on a substrate (for example, Patent Document 1). In this LED module, the side surfaces of the LED device are formed of a fluorescent member or a reflective member, and a plurality of LED devices are arranged such that the fluorescent member of the LED device and the reflective member of another LED device face each other. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2014-143246 Contents of the invention [0006] However, in the LED module of Patent Document 1, when the reflective member of the LED device is arranged at the outermost periphery of the LED module, the light from inside the LED device is reflected by the reflective member positioned at the outermost periphery of the LED module, ...
