Embodiment Construction

[0015] Option 1. 220V 5W and 20W LED lights

[0016] Take a piece of LED lamp bead plate, and install 300 5mm (20mA, 0.065W) LED lamp beads evenly on it. Divide the lamp bead panel into four areas, with 75 lamp beads in each area. Set N=5, 75 lamp beads are divided into five parts and belong to five functional blocks. Each functional block has 15 beads (L=1, M=15) connected in series to form a string of lamp beads with positive pole at one end and negative pole at the other end. Transistor 2N5551, 100Ω 1 / 4W R c Resistor, 10Ω 1 / 4W R b resistance, attached figure 1 Circuit diagram connections. DC power supply 4 Fr107 bridge rectifiers, 0.22 microfarad 275V capacitor filter. Connect the above five functional blocks in series and connect to the power supply to get about 5W, 375 lumens of LED lighting. The other 225 lamp beads in the three districts, 75 in each district, are implemented according to the above method, and share the power supply and auxiliary lamps to make abo...

Abstract

The invention aims at providing the LED (light emitting diode) illuminating technology which is different from technologies adopting a switch power supply and a large-capacity electrolytic capacitor. The invention discloses a novel LED illuminating component with constant-current, constant-voltage and multiple protection functions. The LED illuminating component mainly comprises MXL LED lamp beads, two resistors and function blocks (drawing 1, drawing 2) each of which consists of a transistor and has constant-current, constant-voltage and protection functions; N function blocks are connected in series; alternative current grids of 220V, 120V and 100V can be connected in a mode of a bulb directly through a rectifier power supply. The LED illuminating lamp manufactured by the LED illuminating technology is safe and reliable, is high in illumination quality and applicable for illumination in living rooms; the LED illuminating lamp has less elements and extremely low additional price and almost takes the place of the switch power supply and the large-capacity electrolytic capacitor used in the traditional LED illumination with zero cost; the advantage of super-long service life of the LED lamp bead is supported; and the problem that the large-capacity electrolytic capacitor in the switch power supply has a short service life is solved.

Description

technical field [0001] The invention relates to a novel device capable of implementing constant current and constant voltage power supply for LED lighting beads and providing multiple protections, and its composition and connection circuit. The invention is a method invention, and various LED lighting devices can be manufactured according to the method. With the original new LED lighting device and technology of the present invention, the LED bulbs produced can be reliably, safely and economically applied to 220V, 120V and 100V AC power grids, directly providing high-quality, no flicker, no ultraviolet radiation, no A truly healthy and comfortable lighting source with electromagnetic wave radiation and low heat radiation. The original device and technology of the present invention only need a few resistors and low-power transistors, replace the switching power supply and related auxiliary components with "zero cost", and perfectly realize the constant current, constant voltag...
