[0028] Reference Figures 1-7 For an embodiment of the utility model, an automatic light-adjusting illuminating lamp is provided, which comprises a lamp shell 1, the top of the lamp shell 1 is provided with a lamp hanger 2, the lamp hanger 2 is provided with a first light-dependent resistor 51 and a second light-dependent resistor 52, the inside of the lamp shell 1 is provided with a partition plate 3, the partition plate 3 divides the inside of the lamp shell 1 into a control cavity and an illuminating cavity, the control cavity is provided with a first controller 61, a second controller 62, a first switch 71 and a second switch 72, the illuminating cavity is provided with a first bulb 8 and a second bulb 9, the first light-dependent resistor 51, the first controller 61 and the first switch 71 control the light intensity change of the first bulb 8, and the second light-dependent resistor 52, the second controller 62 and the second switch 72 control the light intensity change of the second bulb 9.

[0029] Reference Figure 1 In the embodiment, the lamp hanger 2 is fixedly connected to the lamp shell 1, the lamp hanger 2 is used for mounting the entire illuminating lamp to a mountable plate such as a roof, and the illuminating lamp is connected to an external power supply through the lamp hanger 2.

[0030] Reference Figures 3-5 And Figure 7 In the embodiment, the lamp shell 1 is a cylindrical cavity structure, the inside of the lamp shell 1 is provided with the partition plate 3, the partition plate 3 divides the inside of the lamp shell 1 into an upper control cavity and a lower illuminating cavity, the control cavity is provided with the first controller 61, the second controller 62, the first switch 71 and the second switch 72, the illuminating cavity is provided with the first bulb 8 and the second bulb 9, the first light-dependent resistor 51 is connected to the input end of the first controller 61, the two ends of the first switch 71 are respectively connected to the output end of the first controller 61 and the first bulb 8, and the second light-dependent resistor 52 is connected to the input end of the second controller 62, the two ends of the second switch 72 are respectively connected to the output end of the second controller 62 and the second bulb 9, and the first switch 71 and the second switch 72 can participate in the adjustment of the light intensity of the first bulb 8 and the second bulb 9 and also can play a role in circuit protection.

[0031] With reference to Figure 5 and Figure 6 In this embodiment, the first bulb 8 is one in number and is arranged at the bottom center of the partition plate 3, and the second bulb 9 is multiple in number and is arranged in a circumferential direction outside the first bulb 8. The first bulb 8 is mainly responsible for adjusting the darkness of the light, and the second bulb 9 is mainly responsible for adjusting the brightness of the light. The brightness of the second bulb 9 is higher than that of the first bulb 8.

[0032] With reference to Figure 5 and Figure 7 In this embodiment, the lower limit preset value of the first controller 61 is lower than that of the second controller 62, and the lower limit preset value of the second controller 62 is less than the upper limit preset value of the first controller 61. Similarly, the upper limit current value of the second bulb 9 is greater than that of the first bulb 8, and the lower limit current value of the second bulb 9 is less than the upper limit current value of the first bulb 8.

[0033] It can be understood that the first light-dependent resistor 51 senses the intensity of external light and feeds back to the first controller 61. The first controller 61 adjusts the light of the first bulb 8 according to the set preset value. When the light is sufficient in the environment, the light is dimmed. When in an environment that needs high-brightness illumination, the light intensity of the first bulb 8 is first adjusted to the upper limit preset value set by the first controller 61. If the light is still insufficient at this time, the second light-dependent resistor 52 transmits a signal to the second controller 62, and the second controller 62 controls the second switch 72 to open the second switch 72 and turn on the second bulb 9. At this time, the second bulb 9 serves as a light source supplement and illuminates together with the first bulb 8. When the light is still insufficient, but reaches the upper limit preset value of the first bulb 8, the first controller 61 controls the first switch 71 to be disconnected to avoid damaging the first bulb 8. Since the upper limit current value of the second bulb 9 is greater than that of the first bulb 8, only the second bulb 9 is turned on at this time, but the light intensity is lower than that when the first bulb 8 and the second bulb 9 work together. Moreover, the second controller 62 will adjust the light intensity of the second bulb 9 according to the change of the external light. When the external light intensity is sufficient, the first bulb 8 works again. The control and adjustment process of the illuminating lamp is dynamically and continuously continued after the illuminating lamp works.

[0034] With reference to Figure 5 In this embodiment, the bottom of the partition plate 3 is provided with a reflecting plate 4. The reflecting plate 4 is used to reflect the light irradiated onto the partition plate 3 to the lower part and the periphery of the lamp housing 1, thereby improving the utilization efficiency of the light and further enhancing the light intensity of the illuminating lamp.

[0036] Reference Figures 1-4 In the embodiment, the material of the light shell 1 is transparent, which further increases the illumination intensity of the illuminating lamp.

[0037] Working principle: the first photoresistor 51 and the second photoresistor 52 sense the external light and transmit signals to the first controller 61 and the second controller 62, the first controller 61 and the second controller 62 adjust the first lamp 8 and the second lamp 9 according to different situations, the light scattered upwards on the partition plate 3 is reflected to the lower part and the surrounding of the light shell 1, so as to improve the utilization rate of the light, the light-shielding baffle 10 can separate the first photoresistor 51 and the second photoresistor 52 from the light generated by the illuminating lamp, so as to improve the accuracy of the first photoresistor 51 and the second photoresistor 52.
