INSTRUCTIONS: [Technical Field of the Invention] The present invention relates to a smart lighting system, and more particularly to a designer who takes into account the strength of the external ambient light and supplements the required illumination by the luminaire. [Prior Art] According to the trend of paying attention to the environment and energy saving, the characteristics of low power consumption, long life, no pollution and high color rendering of the LED are an excellent new generation light source, and gradually have a luminous light. The polar body is the design of the light source of the lighting fixture; however, the place where the lighting is required, in addition to the illumination provided by the lamp itself, there is light from the external environment (such as natural light); however, the design of the general lighting system does not consider the outside. The contribution of the light contrast, so that the lighting fixtures always maintain the same operating current, can not save power; in addition, the LED is operated at the rated current, if its life is 1L, when the operating current is lower than the rated current 1 / 3, because of the influence of temperature and electrical properties, at least its life can be extended to 1.5L (··· 1 / ( 1-1/3) = 1.5), and the relationship of life extension will be greater than this linear equivalence relationship . SUMMARY OF THE INVENTION The main object of the present invention is to solve the problem that the prior art cannot save power, and has the effect of timely power saving. Another object of the present invention is to have the effect of extending the life of the light-emitting diode. Another object of the present invention is to have the effect of color rendering and constant color temperature. In order to achieve the above effects, the structural features of the present invention include: a lamp body having at least one light emitting diode module, and each of the light emitting diodes 200925489 body module contains multiple wavelengths such as red light, green light and blue light. a light-emitting diode; a driving circuit for driving the light-emitting diode module; a first light sensor for sensing an illuminance and a color temperature of an external environment; and a second light sensor for sensing the light body Illumination and color temperature generated; a microprocessor receiving the sensing signals of the first photo sensor and the second photo sensor, and selecting, according to the received sensing signal, a plurality of built-in driving modes The mode is transmitted to the driver circuit in a signal mode of pulse width modulation. 〇 [Embodiment] First, referring to the first figure, the present invention includes: a lamp body (1 〇) having at least one light-emitting diode module (丄i), and each light-emitting diode module The group (1 1 ) contains a multi-wavelength light-emitting diode such as red light, green light and blue light; a driving circuit (2 〇) for driving the light-emitting diode module (work 1); a detector (30) for sensing the illuminance and color temperature of the external environment; a second photo sensor (40) for sensing the illuminance and color temperature generated by the lamp body (1 〇); a microprocessor (50) Receiving a sensing signal of the first photo sensor (3〇) and the second photo sensor (40), and selecting a suitable mode by using several built-in driving modes according to the received sensing signal In the signal mode of PWM (pulse width modulation), it is transmitted to the driving circuit (2 0 ). Based on the composition of the lamp, the amount of light emitted by the lamp body (10) can be determined according to the brightness of the external environment. When the illumination of the external environment is strong, the amount of light emitted can be reduced. 200925489 Achieve timely power saving and prolong the life of the LED. The effect is, when the illumination of the external environment is weak, the amount of light emitted by the lamp body (i 〇) is increased to make up for the insufficient illumination. Furthermore, by using the multi-wavelength light to coordinate with each other, the color rendering and color temperature can be maintained. Constant, no color rendering degradation or color temperature shift due to brightness adjustment. Therefore, the present invention considers the strength of the external environment illumination, and selects a suitable driving mode, and then drives the LED module (ii) to make up the insufficient illumination; therefore, it has a timely power saving and an extended light-emitting diode. The effect of body life.
