Abstract

The invention relates to LEDs, and discloses an LED lamp string with constant-current power supply. The LED lamp string comprises a plurality of lamp string units which are connected in series and energized by a constant-current drive circuit. The lamp string units are formed by connecting in parallel a plurality of LEDs. All LED lamps of the lamp strings of any lengths are basically identical in brightness, the LEDs are connected in parallel and then are connected in series, so that a good light-emitting effect is achieved, and meanwhile, if one or more LED lamps are damaged due to short circuit or circuit break, the overall light-emitting performance can not be affected. The invention further discloses two methods for manufacturing the LED lamp string which is welded on two wires. One method is that the lamp string units are simply disconnected and then are connected in staggered mode, and the other method is that the adjacent lamp string units are welded in a staggered mode and then one wire is disconnected. The LED lamp string has the advantages that manufacturing is simple, cost is low, the length is variable, and luminosity uniformity is good.

Description

technical field [0001] The invention relates to LEDs, in particular to an LED lamp string powered by a constant current and a manufacturing method thereof. Background technique [0002] With the rapid development of social economy, LED, as a powerful tool for advertising and decoration, is becoming more and more popular, and has become an indispensable beautiful landscape for corporate logo publicity and city beautification. With the increasingly intensified competition of products and services in various industries, how to build a unique publicity image for one's own corporate image, products, and logos to attract consumers' attention, the branding strategy has become the top priority of marketing work, "outdoor Various forms of image promotion such as "identification system" and printed materials have increasingly demonstrated their irreplaceable role. LED light string products have been widely used in various places. [0003] LED light strings currently on the market ar...
