Background technique

There are generally two types of lighting fixtures that can be distinguished from the control of the working state. One is to control its constant on or off through fixed switches or buttons, such as street lights in residential areas and parks, and the other is to detect people walking through the corresponding area. Footsteps, voices, sensor buttons or other methods to control its work to automatically turn off after a period of time, such as lighting fixtures in corridors and corridors. The control of the former lamp is relatively simple, but if you forget to turn off the lamp, it will easily cause it to continue to work and waste electric energy; the latter lamp will continue to work after people leave for a long time, which is not conducive to energy saving.

Description of drawings

The utility model will be further described below in conjunction with accompanying drawing and embodiment, in the accompanying drawing:

Fig. 1 is a functional block diagram of the utility model intelligent LED lamp;

Fig. 2 is a functional block diagram of a preferred embodiment of the intelligent LED lamp according to the present invention.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

FIG. 1 is an intelligent LED lamp, which includes an LED lighting module 1 , a detection control unit 3 and an automatic switching unit 2 . The detection control unit 3 is used to detect the distance between the human body and the LED lighting module 1 after entering the preset area, where the boundary of the preset area can be the farthest distance that the detection control unit 3 can detect, or a preset value , when the above-mentioned distance is smaller than this value, the detection control unit 3 uses this value for control. The automatic switching unit 2 controls the brightness of the LED lighting module 1 according to the distance detected by the detection control unit 3. When the distance becomes smaller, the brightness of the LED lighting module 1 is controlled to become larger, and when the distance becomes larger, the brightness of the LED lighting module 1 is controlled to become smaller. . When people are away from the lamps, the lamps will adjust the brightness to a very small level, which can save energy. Moreover, when people leave the above preset area, the lamps can also automatically stop working; in addition, if people are always under the lights, the LED lighting module 1 will still continue to work, without the need to turn on the lighting fixture again through voice control or other sensor buttons. In one embodiment of the present utility model, the minimum brightness of the LED lighting module 1 is 20% of the maximum brightness.

The detection control unit 3 can be, but not limited to, an infrared detector or a microwave detector. Of course, the detected target can be only a human body or any individual (including people or animals) entering a preset area. In addition, how The method of judging that it is a human body rather than other individuals is not the key of the present invention, and will not be repeated here.

As shown in FIG. 2 , the intelligent LED lamp further includes a voice control module 4 , which is used to detect sound and control the switch of the lamp through sound. The voice control module 4 includes a preset storage unit 402 and a voice control switch unit 401 , and the voice control switch unit 401 is connected to the LED lighting module 1 . The prefabricated storage unit 402 is preset with prefabricated control sounds, and the voice-activated switch unit 401 is used to judge whether the user’s voice content is the same as the prefabricated control sounds and to control the LED lighting module 1 at the same time. These prefabricated control sounds correspond to several commonly used control sounds. Instructions, such as turning on the lights, turning off the lights, etc., in order to facilitate the recognition of the sound, the prefabricated sound can include several commonly used expressions of the same action, and of course it can also include expressions in English or even other languages. In addition, an external microphone can also be used for sound input.

The LED lighting module 1 includes a rectification and filtering unit 101 , a constant current unit 102 and an LED assembly 103 connected in series in sequence. The rectification and filtering unit 101 is connected to an external power supply, and the LED assembly 103 is connected to the automatic switching unit 2 . The LED lighting module 1 can be any implementation mode that can make the LED emit light normally, and is not limited to the above one mode. One embodiment of the LED assembly 103 of the present invention is 198 LED diodes connected in series, parallel or mixed.

In addition, the smart LED lamp also includes an electric storage unit 5, which is connected to the rectification and filtering unit 101 and charged through it. When the external power supply is out of power or not connected to the external power supply, the electric storage unit 5 acts as a power supply to provide electric energy for the lamp. .
