Problems solved by technology

However, in the experiment, it was also found that the brightness of the LED with this characteristic can only be maintained at a relatively low level. The reason is that the pulse current with a low duty cycle is difficult to increase, which makes this discovery difficult to be practical.

Embodiment Construction

[0016] like figure 1 As shown, the circuit of the present invention consists of (1) an adjustable constant current source added after the adjustable constant voltage power supply, (2) a multi-pulse generation and trigger counting circuit, (3) an overlapping trigger circuit composed of diodes or gates, and (4) a power drive circuit and other parts. composition.

[0017] like figure 1 As shown, the constant current source is based on the output of the constant voltage power supply, using an adjustable voltage stabilizer integrated circuit such as the voltage stabilizer LM317 or LM350 to connect to the adjustable constant current output, and the resistance value of the resistor R1 can be adjusted to obtain different constant current values. The resistance value of resistor R2, according to the formula I=1.25 / R1; set: R1=1.25Ω, then I=1A; if R1=1Ω, then I=1.25A and so on.

[0018] The oscillating circuit adopts a multi-phase oscillator composed of a 17555MOS time base circuit. I...

Abstract

The invention relates to a multi-pulse overlapping triggering LED (Light Emitting Diode) energy-saving lamp which is characterized by comprising a direct current power supply and an oscillation circuit, wherein the direct current power supply is respectively connected with an input end and an output end of a switch circuit; the switch circuit is serially connected with an LED so as to control the switch-on / off of the LED; the output end of the oscillation circuit is connected with the input end of a pulse distributor so as to generate multiplex pulses; the output end of the pulse distributor is respectively connected with the input end of an OR gate circuit; the output end of the OR gate circuit is connected with a control end of the switch circuit so as to switch on / off the switch circuit according to a pulse signal; and the direct current power supply is also respectively connected with the oscillation circuit and the pulse distributor so as to supply power. The energy-saving lamp provided by the invention can be used for increasing the visual brightness of the LED and causing the energy-saving effect of the LED to be better under high visual brightness.

Description

technical field [0001] The invention relates to a multi-pulse overlapping trigger LED energy-saving lamp. Background technique [0002] The technology of driving LEDs with pulsed power has gradually been valued by the LED industry, especially for human vision, as long as the frequency of the pulsed light source is greater than 50HZ, due to the temporary effect of vision on light, the intermittently emitting light source becomes a continuous light source. Since the pulsed light source is intermittently powered, power can be effectively saved. Using this feature of vision, bionic energy-saving LED lamps can be made. [0003] However, relying solely on visual memory, it is difficult to further improve visual brightness. In recent years, many new studies have been done on the biological characteristics of vision, and it has been found that when the LED light source is triggered by a low duty cycle pulse, the visual brightness has a doubling effect, that is to say, when the LED...
