no. 1 approach

[0124] First, a lighting device according to a first embodiment of the present invention will be described. figure 1 , figure 2 A side sectional view and an exploded perspective view showing the lighting device according to the first embodiment. The lighting device 100 is a light bulb type attached to a lighting fixture, and has a base 32 at one end. An LED module 37 including an LED element 36 is arranged inside the lighting device 100 . The LED module 37 is formed so that the LED element 36 is mounted on the light source board|substrate 37b.

[0125] The appearance of the illuminating device 100 is formed by a lamp cap 32 , a support member 33 , a heat sink 35 and a transmission cover 39 . The lamp cap 32 is formed, for example, of the E26 type and is screwed to a lamp socket powered from the mains. The support member 33 is formed in a cylindrical shape from an insulator such as a resin molded product, and the screw portion 33 a is screwed to the inner surface of the ba...

no. 2 approach

[0139] Next, a lighting device according to a second embodiment of the present invention will be described. image 3 It is an overall perspective view of the lighting device viewed from below. The lighting device 200 constitutes a ceiling light as a lighting fixture, and is installed on a ceiling surface of a room. The lighting device 200 may also be a lighting fixture installed on an indoor side wall.

[0140] The lighting device 200 includes a remote controller (not shown) and a circular and generally plate-shaped main body 1 for illuminating the indoor floor below, and the main body 1 is fixed on the indoor ceiling above. The main body 1 includes a light source substrate 2 , a reflection plate 3 , a frame 4 and an illumination control unit 5 .

[0141] The light source substrate 2 is formed in a rectangular shape in plan view, and is mounted on the lower surface of the main body 1 through the frame 4 in an upright state perpendicular to or substantially perpendicular to t...

no. 3 approach

[0173] Next, a lighting device according to a third embodiment of the present invention will be described. In addition, since the basic structure of this embodiment is the same as that of the above-mentioned second embodiment, the same components as those of the second embodiment are given the same reference numerals as above, and descriptions and descriptions of the drawings are omitted.

[0174] In the lighting device 200 of the third embodiment, Figure 5 The illustrated CPU 11 executes a program in accordance with an operation signal input from the input unit 15 to determine the timing of lighting. For example, the timing of lighting can be determined by pressing a switch not shown. In addition, the timing of lighting may be determined when the preset time is reached by a timer not shown in the figure or when the elapse of the preset time is detected.

[0175] When lighting is commanded, the CPU 11 issues a command to the PWM control circuit 13 so that the white LED elem...

Abstract

This lighting device (100) carries out lighting by outputting lighting light by light emission of LED elements (6). The surface area for 600 - 700 nm in the spectrum of the lighting light is 30 - 70% of the surface area for 400 - 800 nm and additionally the surface area for 400 - 500 nm is 20% or less thereof. The spectrum of the lighting light has a maximum value within 600 - 700 nm, and the spectrum for 550 nm is 50% or less of that maximum value.

Description

technical field [0001] The invention relates to an illuminating device for illuminating a living room. Background technique [0002] Patent Documents 1 and 2 disclose conventional lighting devices. The lighting device of Patent Document 1 illuminates water in a bathtub by changing light color in a predetermined changing pattern. Thereby, the feeling of relaxation at the time of bathing can be improved. [0003] In addition, the lighting device of Patent Document 2 performs lighting by changing the illuminance according to the amount of sunlight. Thereby, the biological rhythm can be adjusted, and the level of alertness can be easily maintained. [0004] Patent Document 1: Japanese Patent Laid-Open Publication No. 2008-53183 [0005] Patent Document 2: Japanese Patent Laid-Open Publication No. Hei 09-306672 [0006] In recent years, there has been a demand to clarify the effects of lighting on the human body existing in its environment. Especially for people with variou...
