Embodiment Construction

[0021] This embodiment is a high-power breathing lamp.

[0022] see figure 1 , figure 2 , the structure of the high-power breathing lamp of the present invention and the combined arrangement structure of the quantized light source include a lampshade 1, a combined light source 2, a control drive circuit board 3, a fixing bolt 4, a mounting seat 5, and a power cord 6; the control drive circuit board 3 is composed of The fixing bolt 4 is fixed on the mounting base 5; the combined light source 2 is composed of several LEDs; the LEDs are distributed on the control driving circuit board, and each LED is connected to its own driving circuit independently or in groups. Multiple groups of LEDs are combined to realize the quantization process of the light source, that is, it is convenient to form a high-power lamp; after the power is turned on, the control circuit controls the LEDs to light up in turn, and then turn off in the opposite order, thereby forming a breathing effect. . C...

Abstract

The invention discloses a high-power breathing lamp which comprises a lamp cover, a combined light source, a power wire and a control driving circuit board which is fixed on a mounting seat through fixed bolts, wherein the combined light source comprises multiple LEDs (Light Emitting Diodes), the LEDs are distributed on the control driving circuit board, and each LED is connected into the respective driving circuit, thereby realizing light source quantization. According to a certain sequence, each group of the LEDs are sequentially turned on, and then each group of the LEDs are turned off according to an opposite sequence, thereby realizing a gradual breathing change course of lamplight from off to on and then from on to off. The high-power breathing lamp disclosed by the invention has the advantages of long service life and high reliability, is energy-saving and environment-friendly, is easy to manufacture, and is simple and convenient. The high-power breathing lamp disclosed by the invention can be widely applied to various ornamentation and decoration occasions such as stage lighting, city lighting at night, automobile lamps, consumer electronics, alarm lamps, airplane stroboscope lamps and the like.

Description

technical field [0001] The invention relates to a breathing lamp device, in particular to a high-power breathing lamp which adopts a plurality of LEDs as a light source and realizes a breathing-style light-to-dark gradual change process by controlling the light-emitting quantity of the LEDs. technical background [0002] The breathing lamp is a special lamp whose brightness changes gradually from dark to bright, and then from bright to dark, which feels like breathing. Due to its special visual effects, it is widely used in various decoration occasions, such as stage lighting, urban night lighting, automotive lamps, consumer electronics, etc. The brightness change of the breathing lamp is mainly realized by controlling the current of the breathing lamp. There are two existing control methods, one is analog, that is to control the current flowing through the lamp to increase continuously from zero to a certain maximum value, during this process, the brightness of the lamp gr...
