Embodiment Construction

[0216] Configuration and operation of semiconductor device

[0217] figure 1 It is a block diagram showing the configuration of a semiconductor device. Such as figure 1 As shown, the semiconductor device 1 of this configuration example includes: a proximity sensor 2, an illuminance sensor 10, a data register 20, an oscillator (OSC) 21, a timing controller 22, a signal output circuit 23, a signal input and output circuit 24, and a drive terminal T1. ~ T3, signal output terminal T4, clock input terminal T5, serial data input and output terminal T6, power supply terminal T7, ground terminals T8 and T9, and test terminal T10.

[0218] Cathodes of infrared LEDs (Light Emitting Diodes) 31 to 33 are connected to drive terminals T1 to T3, respectively. The cathodes of the infrared LEDs 31 to 33 all receive the power supply voltage VDD1. The proximity sensor 2 includes a control circuit 3 , a pulse generator 4 , a driver 5 , an infrared light sensor 6 , an amplifier 7 , an A / D co...

Abstract

An illumination device disclosed in the present specification has a light source, a touchless sensor for detecting proximity and movement of an object without contact, and a control unit for controlling the driving of the light source on the basis of an output of the touchless sensor.

Description

technical field [0001] Among the various technical features disclosed in this specification, the first technical feature relates to, for example, a lighting device having a dimming function and a color adjustment function. [0002] Moreover, the 2nd technical feature among various technical features disclosed in this specification relates to the LED lighting system which illuminates the reading desk in a library, for example. Background technique [0003] 1st Background Art and Its Issues [0004] In recent years, lighting equipment (task light, kitchen lighting, etc.) using LED (Light Emitting Diode) as a light source has been put into practical use. [0005] In addition, Japanese Patent No. 3060478 can be cited as an example of the prior art related to the above. [0006] In addition, compared with the case of using incandescent lamps and fluorescent lamps, the work lights using LEDs can form their housings extremely thin, but correspondingly, because they are thinner, i...
