Adjustable high-definition digital full-color color-changing lamp

Abstract

The invention relates to an adjustable high-definition digital full-color color-changing lamp which comprises a lamp casing, an aluminum substrate, a circuit control panel, a light-transmitting cover, a radiator, a DMX512 address coding device and a dimming button. A light-emitting diode (LED) paster of four colors of red, green, blue and white is installed on the aluminum substrate. Through the DMX512 address coding device, 255 tuning range control systems with adjust brightness ranging from 0 to100% are set in 0-512 programmable addresses, and mixed color modes of single-row, single-set, multi-row and multi-set are adjusted. The adjustable high-definition digital full-color color-changing lamp saves energy and is environment-friendly, beautiful in color and high in fidelity. The adjustable high-definition digital full-color color-changing lamp is strong in penetrability no matter from single-row single-color to multi-color, from single-tube four-color to multi-color and whole lamp full-color. Light emitting angle is large, and light spreading is even. A lamp panel and a luminous source do not need to be changed in 50000 hours, using cost and maintenance cost are saved, and color is consistent and uniform. No matter the adjustable high-definition digital full-color color-changing lamp is adjusted manually or through a light dimming desk, a manual, semi-automatic and full-automatic system integrating digitization can be achieved.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to an adjustable high-definition digital full-color color-changing lamp. Background technique [0002] DMX512 is the abbreviation of DigitalMultiplex with 512 pieces of information in English. It is a digital communication network standard. Its simplicity and good dynamic dimming effect are widely used in the field of stage lighting and LED lighting. [0003] Large-scale performance stage set color matching, advertising film set-up, film and television drama set-up and other occasions need to use stage lighting lights. The existing stage lighting lights often use the traditional RGBW light tube or LED light mode. Conventional The disadvantages of the fluorescent tube mode are: single-tube monochrome, limited effective time, frequent replacement, and poor coordination of color difference performance; the disadvantages of the LED lamp mode are: the LED3014 chip itself is very small, a...

[0003] Large-scale performance stage set color matching, advertising film set-up, film and television drama set-up and other occasions need to use stage lighting lights. The existing stage lighting lights often use the traditional RGBW light tube or LED light mode. Conventional The disadvantages of the fluorescent tube mode are: single-tube monochrome, limited effective time, frequent replacement, and poor coordination of color difference performance; the disadvantages of the LED lamp mode are: the LED3014 chip itself is very small, and it is packaged into a single RGB patch. Equipped with w patches, they are installed on the pcB aluminum substrate with a width of 24.5mm; since the voltage values ​​of the four patches are inconsistent and they need to emit better effects and normal brightness values, a single row of voltage must be used on the circuit. The design concept of color tone is a waste of power, and it is not easy to control the color tone
