Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below.

[0022] In one embodiment, a new type of sound-activated LED lamp includes a sound pickup module, an LED driver module, an LED light source and an external heat sink,

[0023] The pickup module includes an electret microphone, an amplifying circuit, a shaping circuit and a delay circuit. After receiving a sound signal of a certain intensity, the electret microphone converts the sound signal into a voltage signal, and the voltage signal is amplified , After shaping, trigger the monostable delay circuit to generate a pulse signal with adjustable width, and prolong the steady-state time of the pulse signal at the same time, and transmit the pulse signal to the LED driver module for driving the LED to light up.

[0024] The LED drive module is a dimmable constant current drive circuit, and the drive circuit inclu...

Abstract

The invention relates to a novel voice-activated LED lamp comprising a voice pickup module, an LED drive module, an LED light source, and an external heat dissipation element. The LED drive module is a light-adjustable constant-current drive circuit which includes a DC-DC booster module, a power-on gradual brightening module, a constant-current module, and a protection circuit. The voice pickup element is used to sense voice and convert a voice signal into a pulse signal capable of controlling the LED circuit. Therefore, on-off of the LED light source is controlled automatically, and the LED lamp is made intelligent. By designing the LED drive circuit, the system stability and conversion efficiency are improved. In addition, the heat dissipation problem of the LED lamp is solved effectively through the unique heat dissipation structure design. The novel voice-activated LED lamp of the invention has the advantages of high degree of intelligence, low cost, high stability, high conversion efficiency, high safety, and high practicability.

Description

technical field [0001] The invention relates to the field of automatic lighting, in particular to a novel sound-activated LED lamp. Background technique [0002] LED is a light-emitting diode, a new technology developed in the middle of the 20th century. It relies on the energy transition generated by the electrons in the semiconductor heterojunction through the potential barrier to directly emit light. Lamps made of LEDs are energy-saving, environmentally friendly, and have a long lifespan, which is the continuous development direction of lighting technology. However, as we all know, electric energy is a non-renewable secondary energy source, and it is also the most widely used energy source in the world today. Under the situation of energy saving and emission reduction, saving energy, especially electric energy is an important strategic task. Among the many forms of electric light source lighting, most of the light sources cannot be turned on or off intelligently, and l...
