Problems solved by technology

Moreover, because the power supply uses electrolytic capacitors (the life of good quality is generally 3000 hours, and the price is more expensive), the life is far from that of LED chips, which seriously affects the popularity of LED lighting in the household field.

Abstract

The invention relates to the illumination field, in particular to a full-chip integrated AC LED light source. The full-chip integrated AC LED light source comprises a bridge rectifier circuit, a constant current tube, multiple LED chips and a substrate. A power contract is arranged on the substrate. The input end of the bridge rectifier circuit is connected with an alternating current power supply through the power contact. The output end of the bridge rectifier circuit is electrically connected with the input end of the constant current tube. The output end of the constant current tube is electrically connected with the LED chips. The bridge rectifier circuit, the constant current tube and the LED chips are all unpacked chips and are arranged on the substrate by means of a WB technology. The substrate is an aluminum oxide ceramic substrate. According to the full-chip integrated AC LED light source, good heat dissipation performance and pressure-resistant performance can be realized, and the safety performance is more reliable.

Description

technical field [0001] The present invention relates to the lighting field, in particular to a full-chip integrated AC LED light source, which directly uses high-voltage alternating current (220 / 230V) LED (Light Emitting Diode) without any additional components. Chip integrated light source. Realized the technological breakthrough from DC (Direct Current) LED to AC (Alternating Current) LED. Background technique [0002] Because the LED chips in ordinary LED light sources must be supplied with appropriate DC power to emit light normally, the power supply voltage is usually between 3.0-3.3V, and if the voltage is higher than 3.5V, the current will increase sharply, causing the LED to burn out. Therefore, the alternating current AC used in daily life cannot directly supply power to the LED light source. It must first convert the alternating current to direct current DC through an external power control part, and then convert from high voltage to low voltage, so that the LED c...
