Full combination efficiency LED lamp

Abstract

A full combination efficiency LED light is connected by a super interference absorber and a protective driving module, in which the super interference absorber is used for absorbing super interference signal; protective driving module is used for rectifing, filtering, stabilizing and changing level of the alternating 220V voltage, including rectifing circuit, filter circuit, stabilizer circuit, LED array driver, LED array circuit and energy-saving controller. The invention can limit the electric network super interference in a small range or stop it and separate from the LED array by LED array driver so as to avoid LED premature decay by the effect of interference signal and prolong the LED light service life. Furthermore, the invention gives up the driver level transition made up of micro-electronics element and having decompression element so that the power loss of the LED light is decreased notably and the combination efficiency is improved. Meanwhile, the invention can also avoid the power loss by resistance decompression.

Description

technical field [0001] The invention relates to a kind of microelectronics used in electric lighting and lamp decoration, especially LED lamp with full combined efficiency. Background technique [0002] The luminous efficiency η of an electric light source refers to the luminous flux Φ produced by consuming a unit of electric power P. which is: [0003] η=Φ / P (1) [0004] The luminous efficiency of an LED refers to the ratio of the luminous flux emitted by the LED to the power consumption of the LED itself (excluding accessories). [0005] The luminous efficiency of LED is much higher than that of conventional light sources, and it will be one of the future directions to combine LEDs into lighting or landscape lights. [0006] Usually LED lights are composed of LED arrays, and the luminous efficiency of LED lights η 1 Equal to the total luminous flux Φ emitted by the LED lamp 1 Active power P absorbed by the LED lamp from the grid 1 ratio, namely:...

AI Technical Summary

Problems solved by technology

In turn, the combined efficiency of LED lights is significantly reduced

[0022] (2) LED anti-interference ability is poor, in the face of high-energy interference such as lightning shock wave refraction wave, electrostatic induction lightning wave, high potential counterattack, surge, harmonic, neutral line disconnection, etc., it is easy to damage some or all LEDs

Moreover, zinc oxide surge protectors cannot effectively protect

[0023] (3) The operating conditions of LED lamps do not match, which will cause some LEDs to deteriorate and shorten their life.

[0024] (4) As far as the existing technology is concerned, when controlling "power-saving operation" of LED lights, resistors (potentiometers) are often used to step down the voltage, which often leads to a decrease in LED luminous efficiency η or premature aging of some LEDs

[0025] In short, although LED has high luminous efficiency and long service life, the luminous efficiency of LED lamps is not necessarily high, and the service life is not necessarily long.
