Description

technical field [0001] The invention relates to an LED dimming lamp device, in particular to a lamp capable of arbitrarily changing the illuminance according to the different demands on the light intensity of the place of use and having uniform brightness in the irradiated area, which belongs to the field of energy-saving LED lamp control. Background technique [0002] With the advancement of science and technology and society, lamps have also gradually changed, from incandescent lamps with high power consumption and low luminous rate to fluorescent lamps with low power consumption, high luminous rate but short life, from cheap, low energy consumption, luminous The color of the high-efficiency energy-saving lamps can be changed by remote control. The life of the lamp is longer and the volume is smaller. In the next few decades, the all-powerful LED lamps, LED lamps have long working life, low power consumption, and responsiveness. Fast time, small size, light weight, impact ...

AI Technical Summary

Problems solved by technology

The greater the power, the greater the maintenance current required. If the maintenance current is not enough, the conduction angle will be unstable, the output waveform will be uneven, and vibration and spikes will occur. When such an unstable output is applied to the LED flashes when on

Because the previous incandescent lamps are linear loads, and the operating current generally exceeds 50mA, there will be no flickering phenomenon. Therefore, the thyristor dimmers suitable for incandescent lamps on the market are not directly applicable to LED products, and need to be adjusted. Make design improvements to match the operating characteristics of LEDs
