Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] see figure 1 , figure 2 As shown, the present invention includes an ambient illuminance collection part, an A / D conversion part, a central control part and a light emitting element. Wherein, the ambient illuminance collection part is used to collect the intensity parameters of the ambient light and convert them into analog electrical signals, which is mainly composed of a light sensor and a signal amplifier. The light sensor converts the light intensity of the surrounding environment into an electrical signal and outputs it to the signal amplifier, and the signal amplifier amplifies the weak signal from the light sensor for subsequent signal processing. The light sensor can be a photoresistor, a photodiode or a phototransistor.

[0015] The A / D conversion part is used to sample the electrical signal from the ambient light collection part and conver...

Abstract

The present invention discloses an energy saving illuminating apparatus, which comprises at least a light-emitting element. The energy saving illuminating apparatus also comprises an illumination collecting part, an A / D converting part, and a central controlling part. The illumination collecting part consisting of an optical sensor and a signal amplifier is used for collecting the illumination around the energy saving illuminating apparatus and for converting the illumination signal to a simulative electrical signal which is amplified by the signal amplifier; the A / D converting part mainly comprises an A / D converter, which is used for sampling the electrical signal sent by the illumination collecting part around and for converting the electrical signal to digital signal for output; the central controlling part consists of a central processing unit, a memorizer and a timer, the central controlling part receives the digital signal outputted by the A / D converting part and judges the light intensity around the illuminating apparatus and compares the light intensity with a scheduled value. In addition, the central controlling part adjusts the voltage or the electric current exerted on the energy saving illuminating apparatus according to the result of judgment, so the light intensity around the energy saving illuminating apparatus is kept in the scheduled value.

Description

【Technical field】 [0001] The invention relates to an illuminating device, more specifically, to an illuminating device capable of saving electric energy. 【Background technique】 [0002] At present, the global energy supply is tense, and all countries are vigorously developing new luminescent materials to replace traditional lighting materials in order to save electric energy. Save a lot of electric energy. But on the other hand, all the lamps and lanterns used for lighting have been running at a predetermined power since they were lit, even when the external light is relatively strong, only weak lighting can meet the requirements of normal life or work. , also run at predetermined power. Since the brightness of the existing lighting device cannot be automatically adjusted, the lighting device that does not have to run at full power still runs at the rated power, which wastes a lot of electric energy. 【Content of invention】 [0003] The technical problem to be solved by ...
