For example, a household lighting fixture using a light-emitting diode light source has the advantages of fast warming time, fast reaction speed, small volume, long life, power saving, shock resistance, low pollution degree, high reliability and suitable mass production. The advantages of traditional incandescent bulbs and neon lights have gradually been replaced. In addition, since environmental protection issues such as energy saving and carbon reduction have been continuously proposed, it is an important subject worthy of exploration and concern for how to make energy-saving and power-saving effects of lighting devices using light-emitting diodes as light-emitting sources. Most of the existing power-saving methods are provided with a light sensor for detecting the ambient brightness of the square, ', , and Ming clothes. When detecting that the ambient brightness of the surrounding environment is lower than the preset standard value, The lighting device is activated to provide a lighting function. In the following, when the illumination device is a downlight structure and when the illumination is ιν^^δ5〇3 24 'the light-emitting diodes are disposed on the socket 22 and used to provide illumination light, and the lamp cover 23 is used for the lamp holder 22 Combining, and covering the light-emitting diodes, where the 'light-sensing element 24 is disposed on the bottom surface of the lamp holder 22, for detecting the ambient brightness' - the preset standard value 4' causes the dimming diode unit 21 to provide illumination light, and the illumination brightness provided by the illumination diode 21 is modulated according to the result of the sensing of the photo sensing element 24. The brightness of the illumination that should be output, such as the ambient brightness measured by the light sensor (4) is smaller, then the light-emitting diode is single; the brightness of the illumination provided by 21 is greater. Although the conventional lighting device has been able to determine whether it provides illumination or adjust the brightness of the illumination by detecting the ambient brightness of the light sensor, thereby achieving the effect of energy saving and power saving, but the light sensor is subject to The effect of the light source output by the illuminating device is too large to objectively sense the actual brightness of the surrounding environment. Taking the above-described downlight structure 丨 as an example, since the light sensing element 丨 4 is disposed almost flush with the light exiting surface 丨 5 ′ of the downlight structure 1 , the light sensing element 14 can easily receive more light than the surrounding environment. 'The result of sensing the result will be higher than the actual value of the surrounding ambient brightness' & and because the illumination brightness provided by the light-emitting diodes & η is small, it can not meet the needs of users. Taking the above-mentioned ceiling lamp structure 2 as an example, since the light-emitting surface 23 of the ceiling lamp structure 2 is 232 (where the light-emitting surface is a curved surface, that is, the entire surface of the lamp cover 23), the light-emitting diode units 21 (light source) and light are located. Between the sensing elements 24, the light sensing element 24 is directly exposed to the light provided by the light emitting diode units 2, so that the result sensed by the M428503 is higher than the actual value of the surrounding ambient brightness. In addition, the illumination brightness provided by the light-emitting diodes u is relatively small, and the user's needs are met. As can be seen from the above description, the conventional lighting device is prone to a situation in which the sensing result is not satisfactory due to the position of the optical sensor. Therefore, there is room for improvement.

In the preferred embodiment, the illuminating device 4A is a ceiling lamp structure, including a illuminator 4, a lamp holder 42, a lamp cover 43 and a light sensing component. The illuminating body is disposed on the lamp holder 42 for providing illumination light. The lamp cover 43 is used to cover the illuminant and is combined with the lamp holder 42. The illumination light provided by the illuminator 4 向外 is outputted through the lamp cover 43 and the outer surface of the lamp cover 43 is the embodiment. The illuminating device is from the light-emitting surface 43 432, but the lamp cover 43 is not an essential element for defining the embodiment. In the preferred embodiment, the illuminator 41 includes a plurality of illuminating diode units 4' and any of the photo sensing elements 44 is a wire resistor. The light sensing elements 44 are disposed in different directions on the side surfaces of the lamp holders 42. Therefore, the positions of the light sensing elements 44 are disposed on the light emitting surface 43 of the illumination device 4A.
