Embodiment 1

[0062] The mains electricity is 220V, 50HZ in China.

[0063] An LED power supply method converts AC power into DC power through rectification; intercepts the highest part of the voltage through the circuit to form intermittent power to power LEDs.

[0064] Specifically, the 50 Hz city test power is rectified to obtain 100 Hz pulsed direct current, the intercepted peak voltage band is 280-312V, and the output pulse power is used to drive the LED lighting system.

[0065] The market prospect of this patent: This patent solves three problems in the LED lighting system: one is to save power consumption by 20-80%; The amount of heat generation is reduced by 30-80%. The manufacturing process reduces the use of aluminum for heat dissipation. The manufacturing cost of the lighting system of the LED lamp is reduced.

[0066] When the application scenario is 100V in Japan or 110V in the United States, please perform a similar deduction.

[0067] The application scenario is 100V main...

Abstract

The invention discloses an LED power supply method and module and an LED lamp, wherein the method, the module and the LED lamp are used for LED lighting fields. According to the invention, after commercial power is rectified, only a relatively high voltage part is intercepted for supplying power to LED equipment, the LED equipment has light-emitting continuity due to energy conservation, and high-frequency flicker cannot be perceived by human eyes, so that energy consumption of LED equipment is reduced, energy is saved by 30-80% for pulse power supply of the LED lighting equipment, the heat productivity is reduced by 50-80%, the lamp manufacturing cost is low, the service life of an LED lamp wick is long (the service life is prolonged through high-frequency intermittent work), and constant-current and constant-voltage double-layer protection measures are designed in a driving circuit.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED power supply method, a module and an LED lamp. Background technique [0002] LED lighting, also known as semiconductor lighting or light-emitting diode lighting, is an existing mainstream lighting method. It uses a solid semiconductor chip as a light-emitting material. In the semiconductor, the excess energy is released through the recombination of carriers to cause photon emission, and directly emits red, yellow, blue, and green light. On this basis, using the principle of three primary colors, Adding fluorescent powder can emit light of any color. The lighting fixtures manufactured using LEDs as light sources are LED lamps. LED lighting has low power consumption, high brightness, and long life, and is loved by everyone. However, LED lighting has the disadvantage of generating heat and greatly reducing life, which restricts its application difficulty in high-power scenarios....
