Abstract

The invention provides a light source module, surface area light-emitting unit, and surface area light-emitting device that have versatility, where installation work is simplified and production costs are reduced, and where irregularity of light emission and color is sufficiently suppressed. The light source module has a light direction-converting optical element (29) and an LED (28). The light direction-converting optical element (29) has a recess (290) with a light incident surface (29A) into which light enters, a light reflecting surface (29B) for reflecting light entered from the light incident surface (29A), and a light emitting surface (29C) for emitting to a side the light reflected by the light reflecting surface (29B). The LED (28) is placed in a recess (290) of the light direction-converting optical element (29) with a gap provided in between them and applies light to the light incident surface (29A).

Description

technical field [0001] The present invention relates to a light source module, a surface emitting module, and a surface emitting device, and more particularly, to a light source module, a surface emitting module, and a surface emitting device using a light emitting diode (Light Emitting Diode: LED) as a light emitting part. Background technique [0002] As is well known, fluorescent lamps are generally used as light sources in surface light-emitting devices used for displaying images, signboards, etc., and for store lighting. However, since fluorescent lamps use harmful mercury, there is a problem that proper disposal of industrial waste is required. In addition, fluorescent lamps have a short lifespan and high running costs. [0003] In recent years, technology using LEDs has been proposed as a light-emitting lamp of a surface light-emitting device that solves such a problem. Since LEDs are manufactured based on semiconductor manufacturing technology, they have excellent ...
