Embodiment approach 1

[0031] Below, based on Figure 1 to Figure 7 The lighting device 10 of this embodiment will be described. based on figure 1 and image 3 The lighting system 20 of this embodiment will be described based on Figure 8 The moving body 30 will be described. In the drawings, the same reference numerals are attached to the same components, and repeated explanations are omitted. The size and positional relationship of components shown in the drawings may be exaggerated for clarity of description. In the following description, each element constituting the present embodiment may be constituted by a single component, and one component may also serve as a plurality of elements, or the function of one component may be shared and realized by a plurality of components.

[0032] The lighting device 10 of this embodiment is as figure 1 As shown, a light source unit 1a, a sensor 2 and a control unit 3 are provided. The sensor 2 detects the light quantity of the light source unit 1a. T...

Embodiment approach 2

[0094] The main difference of the lighting device 10 of this embodiment is that the figure 2 or Figure 4 The control shown in Embodiment 1 becomes Figure 9 The structure of the control shown. In the lighting device 10 , by appropriately changing the program stored in the storage unit 3 a 1 of the drive control unit 3 a , control of lighting of the light source unit 1 a and detection of the light quantity of the sensor 2 can be appropriately changed. The lighting system 20 of this embodiment can be figure 1 The shown configuration of the lighting system 20 is configured by changing the program. For the same components as those in Embodiment 1, the same reference numerals are used and descriptions are appropriately omitted.

[0095] In the lighting device 10 according to the present embodiment, the control unit 3 performs phase difference control. In the phase difference control, the timing for starting light emission only from the light source of the detection target who...

Embodiment approach 3

[0110] Figure 11 to Figure 14 The main difference of the lighting device 10 of the present embodiment shown is that, compared to figure 1 The sensor 2 according to Embodiment 1 shown mainly detects the light quantity of the light source unit 1 a in the lighting device 10 provided with the sensor 2 , and also detects the light quantity of other lighting devices 10 . Below, based on Figure 11 , Figure 12 , Figure 14 The lighting system 20 of this embodiment will be described based on Figure 14 The moving body 30 will be described. Regarding the same components as those in Embodiment 1 and Embodiment 2, the same reference numerals are used and descriptions are appropriately omitted.

[0111] In the lighting system 20 including the lighting device 10 of this embodiment, a plurality of lighting devices 10 are arranged in a row. Figure 11 , Figure 12 as well as Figure 14 In the figure, four are illustrated as the plurality of lighting devices 10 . Hereinafter, the f...

Abstract

PROBLEM TO BE SOLVED: To provide an illumination device that has less dispersion in light output, and an illumination system and a mobile body that have the same. SOLUTION: An illumination device 10 includes a light source 1a, a sensor 2, and a controller 3. The light source 1a has a first light source 1f and a second light source 1s. The controller 3 sets, as one cycle, a pair of a first period when only the light source 1a as a detection target is caused to emit light and a second period when the first light source 1f and the second light 1s are caused to emit light, and controls to repeat plural cycles so that the composite light of the first light source 1f and the light of the second light source 1s have the same light output in the respective one cycles. The sensor 2 outputs a detection value obtained by detecting the light amount of the light source 1a in the first period. Further, the controller 3 controls the light source 1a so that the light amount of the light source 1a is converged into a target range, based on a detection result where the detection value corresponds to a value detected at a predetermined number of times.

Description

technical field [0001] The present invention relates to a lighting device, a lighting system including the lighting device, and a moving body. Background technique [0002] Currently, a lighting device that detects the light intensity of a light source with a sensor and controls lighting of the light source based on the detection result of the sensor is being developed. [0003] As a structure that can be used in such a lighting device, for example, a structure having a plurality of LED (Light Emitting Diode) chips, a light detection element as a sensor, a plurality of switching elements, and a control unit is known (for example, refer to document 1 (Japanese Laid-Open Patent Publication No. 2009-206186)). [0004] The photodetection element of Document 1 detects light emitted from a plurality of LED chips having different emission colors. Each switching element is inserted into a power supply path that supplies power to the corresponding LED chip. The control unit perfor...
