Problems solved by technology

The device detects the intensity of ambient light through the ambient brightness detection sensor, and automatically adjusts the brightness of the LED lamp through the LED brightness control circuit. However, the device can only change the brightness of the LED, and cannot change the color of the lamp. The control is relatively simple, so The unit needs to be improved

Embodiment 1

[0022] see Figure 1-3 , an LED lamp with adjustable light intensity, comprising a base plate 1, a column 2 is provided in the middle of the upper surface of the base plate 1, a fixed rod 3 is provided in the middle of the column 2, and a lamp cap 7 is provided at the right end of the fixed rod 3, and the lamp cap 7 A circuit board 10 is provided in the middle of the upper surface of the lamp holder 7, and a first light transmission hole 11 is provided on the upper right side wall of the lamp holder 7. The first light transmission hole 11 is connected to the illuminance sensor 12, and the illuminance sensor 12 can sense the light intensity in the external environment. Because the illuminance sensor 12 belongs to the commonly used sensor, and the control mode is also comparatively conventional, so its working process is not described in detail; The circuit board 10 is connected through the first wire 9, and the storage battery 8 supplies power to the whole device.

Abstract

The invention relates to the technical field of illumination adjustment, and discloses an LED lamp capable of adjusting the illumination intensity. The LED lamp comprises a bottom plate; a stand column is arranged in the middle of the upper surface of the bottom plate; a fixed rod is arranged in the middle of the stand column; a lamp cap is arranged at the right end of the fixed rod; a circuit board is arranged in the middle of the upper surface of the lamp cap; a first light transmitting hole is formed in the upper part of the right side wall of the lamp cap; the first light transmitting holeis clamped with an illumination intensity sensor; a driving motor is arranged on the right side of the lamp cap; an output shaft of the driving motor is fixedly connected with a first bevel gear; thefirst bevel gear is in meshed connection with a second bevel gear; the second bevel gear is fixedly connected with the upper end of a rotating shaft; and a light shielding plate is arranged at the lower end of the rotating shaft. According to the LED lamp capable of adjusting the illumination intensity, the illumination intensity sensor is arranged for sensing the light intensity in the externalenvironment, so that the illumination intensity of the LED lamp can be automatically adjusted; and the light shielding plate can be driven by the driving motor to rotate for changing a corresponding light filter plate at the lower portion of a second light transmitting hole, so that the color of light can be changed.

Description

technical field [0001] The invention relates to the technical field of light adjustment, in particular to an LED lamp with adjustable light intensity. Background technique [0002] The global energy is increasingly tense, and countries are advocating energy saving and looking for various ways to save energy. Among them, LED light-emitting diodes have the advantages of energy saving, long life, high luminous efficiency, no radiation, and impact resistance. The current LED lights are basically monochromatic. (white) and multi-color adjustable, compared with the previous ordinary lights, the intensity of light is greater and the lighting effect is better, so it has been well promoted; LED lights are also widely used in the field of street lights, but for different time and The environment requires street lamps to emit light of different intensities. At this time, it is necessary to fine-tune the light intensity of street lamps. [0003] Chinese patent (notification number: CN2...
