Abstract
The invention discloses an LED fluorescent lamp without resistor energy consumption. A resistive and capacitive pressure relief circuit is used as a driving circuit of the LED fluorescent lamp. A resistor serving as a bleeder resistor in the resistive and capacitive pressure relief circuit is arranged in the driving circuit and no other resistor is arranged in the driving circuit so that electric power absorbed from the circuit by the LED fluorescent lamp can be converted into luminous energy to the maximum extent. Due to the fact that the resistive and capacitive pressure relief circuit has the characteristics of constant current electricity supply and small load adaptation, when the driving circuit of the LED fluorescent lamp is designed, the design of two driving circuits with the same parameter is adopted. Smooth direct currents output by the two driving circuits are overlapped and used for being supplied to an LED fluorescent lamp operation power source. The LED fluorescent lamp manufactured according to the designed circuits is proved to be reasonable in circuit design through practical use for several years. The LED fluorescent lamp is high in energy-saving efficiency and good in durability.
Description
Technical field
The present invention relates to a kind of LED fluorescent lamp that does not have the resistance power consumption.
Background technology
LED fluorescent lamp in the market, its drive circuit all are the resistive elements that has more or less.Because resistive element is dissipative cell, like this, the LED fluorescent lamp on the market, its energy-saving efficiency are all because the resistive element in the drive circuit is subject to impact more or less.
Summary of the invention
A kind of LED fluorescent lamp that does not have the resistance power consumption of the design uses the resistance-capacitance depressurization drive circuit, and the whole drive circuit resistive element to a consume electric energy useless.Like this, the LED fluorescent lamp just can turn to luminous energy to greatest extent from the electric energy that power supply absorbs.During specific design, have constant current and the characteristics that are applicable to little load according to capacitance-resistance voltage reduction circuit, the capacitance-resistance that the LED fluorescent lamp is used and drive circuit are divided into two equivalent circuit, the element of every part of circuit is installed in the both sides of pcb board, in order to dispel the heat, the electric capacity of especially resistance-capacitance depressurization being used is divided into some minutes, is installed on the pcb board equably.Two drive circuits obtain level and smooth direct current and are superimposed again by after step-down, rectification, the compound filter, jointly supply with the working power of LED fluorescent lamp.
A kind of LED fluorescent lamp that does not have the resistance power consumption, its circuit structure is simple, and fluorescent tube is selected and is aimed at the PC plastics fluorescent tube that the LED fluorescent lamp is made.Respectively there is aluminum (or plastics) plug at two of fluorescent tube, draws two metal connecting terminals in the middle of the plug.By binding post, the working power of giving the LED fluorescent lamp civil power 220V power supply.
A kind of LED fluorescent lamp that does not have resistance power consumption, the PCB circuit board in its PV pipe, with drive circuit and light-emitting diode (LED), namely AC and DC circuit integral body be installed in a block length 1180MM, on the PCB circuit board of wide 27MM.
On the PCB of LED fluorescent lamp circuit board, two ends respectively are the position about 30MM, the rectification of two groups of drive circuits, the element of filter circuit are installed, and the resistance that resistance-capacitance depressurization is used, capacity cell, press the capacity of the required electric capacity of LED fluorescent lamp, be divided into the only little electric capacity of youngster, every electric capacity withstand voltage more than 400V, then little electric capacity equably distributing installation on the circuit of the both sides of pcb board.The drive circuit at pcb board two ends, after step-down, rectification, filtering, the smooth direct current electricity of output is superimposed by positive and negative electrode, and is arranged in the both sides of LED lamp pearl with positive and negative two telegram in reply roads.The central mounted LED lamp bulb of pcb board, model are paster 5050 (5252) encapsulation.Take 6 series connection as an elementary cell, be connected to by both positive and negative polarity on the electric power loop on next door in the LED lamp pearl.As required, can and connect 10 elementary cell to 12 elementary cells.
Description of drawings
Accompanying drawing is a kind of circuit theory diagrams that do not have the LED fluorescent lamp of resistance power consumption.
Embodiment
