Low-power consumption constant-current LED lamp

Abstract

The invention discloses a low-power consumption constant-current LED lamp, which comprises a base, a support rod, a lamp holder, LED lamp beads, a receiving module, a judging module and a control module, wherein the receiving module receives sound inputted from the outside, and the sound is converted to corresponding sound signals; the receiving module transmits the sound signals to the judging module; and the judging module receives the sound signals, makes a judgment and generates a first-gear brightness instruction, a second-gear brightness instruction, a third-gear brightness instruction,a fourth-gear brightness instruction or a fifth-gear brightness instruction. The low-power consumption constant-current LED lamp has the beneficial effects that the receiving module receives the soundinputted from the outside and converts the sound to the sound signals, the judging module converts the sound signals to a corresponding brightness instruction according to the information representedby the sound signals, the control module controls the LED lamp beads to turn on the lamp according to the brightness instruction, the light brightness is adjusted along with changes of the outside environment, and too strong or too weak light can be prevented from hurting eyes of a person.

Description

technical field [0001] The invention relates to a constant current LED lamp with low power consumption. Background technique [0002] As we all know, a desk lamp is a kind of lamp, and this electrical appliance is mainly placed on a desk or a dining table for lighting purposes. The light irradiation range of the desk lamp is relatively small and concentrated, so it will not affect the light of the whole room. It is not possible to adjust the brightness of the light with the change of the external environment, so the brightness of the light that is too strong or too weak will hurt people's eyes. [0003] Therefore, there is an urgent need for a low-power constant-current LED lamp to adjust the brightness of the light as the external environment changes, so as to avoid damage to people's eyes by too strong or too weak light brightness. Contents of the invention [0004] The purpose of the present invention is to provide a constant current LED lamp with low power consumptio...
