Embodiment Construction

[0146] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, the front-back, left-right, and up-down directions in the following description are based on the directions of the arrows in the drawings.

[0147] In this embodiment, the LED module 10 is used as the lighting fixture 66 (refer to Figure 26 ~ Figure 30 ) light source for use.

[0148] LED module 10 (semiconductor light emitting element module) is carried out by installing LED 62, bonding wire 64, and sealant (and further, bonding wire 90 described later as the case may be) on LED bracket 15 (semiconductor light emitting element bracket). integrated and formed. First, the detailed structure and manufacturing method of the bracket 15 for LEDs are demonstrated.

[0149] figure 1 The conducting plate 17 which is the base material of the socket 15 for LEDs is shown. The conduction plate 17 is formed by press-molding a metal flat plate having excellent elec...

Abstract

The invention provides a lighting device which can realize no over-complicated surface shape of a light distribution lens and efficiently emits illuminating light of a semiconductor light-emitting element relative to an orthogonal direction relative to the opposite direction of a semiconductor light emitting element and the optical element. The lighting device is provided with the components of substrate components (30,45,54), the semiconductor light-emitting element (62) which is fixed on the substrate component, and an optical element (70) which opposes the semiconductor light-emitting element; wherein the optical element is provided with a projected part (74) which projects to the semiconductor light-emitting element side, and oblique reflection surfaces (73b,74a). The oblique reflection surfaces (73b,74a) are formed outside the projected part and incline relative to a linear reference line (AL) which extends in an opposite direction of the semiconductor light emitting element and the optical element, and furthermore a distance to the orthogonal direction of the reference line gradually reduces along with extension from the optical element side to the semiconductor light-emitting element side.

Description

technical field [0001] The present invention relates to a lighting fixture using a semiconductor light emitting element (LED). Background technique [0002] As a conventional example of a lighting fixture using a semiconductor light emitting element (LED), there is a lighting fixture disclosed in Patent Document 1, for example. [0003] This lighting fixture includes a base member, an LED (semiconductor light emitting element) fixed to the base member, and a light distribution lens (optical element) fixed to the base member. [0004] Since the light generated by the LED has high rectilinearity, regardless of the shape of the light distribution lens, the illumination light of the LED passing through the light distribution lens hardly diffuses, and travels in a specific direction (and its peripheral portion). However, when the light distribution lens exhibits such light distribution characteristics, the practicality of the lighting fixture decreases. [0005] Therefore, in P...
