Embodiment

[0021] An integrated method of an LED lighting circuit, the method is to package a rectifier circuit (including a rectifier bridge or / and a rectifier diode), a constant current diode and an LED light-emitting diode in the LED lighting circuit together to form an LED lighting integrated chip (circuit structured as figure 1 shown). The LED lighting integrated chip can also be directly packaged on an LED bracket by existing rectifier circuit chips (bare chips), constant current diode chips (bare chips) and LED light-emitting diode chips (bare chips), and the above-mentioned components share a package. The LED lighting integrated chip leads out to the adjustment terminal of the constant current diode and the power interface. The LED lighting integrated chip is also connected to capacitors with external leads (usually, the capacitors do not need to be welded into the circuit). The LED lighting circuit includes a power supply, both ends of the power supply are connected to the inp...

Abstract

The invention discloses an integration method of an LED lighting circuit and an LED lighting integrated chip, the integration method is characterized in that a rectification circuit, a constant-current diode and an LED in the LED lighting circuit are packaged together to form the LED lighting integrated chip, and a lamp enterprise can obtain LED lamp products only by welding the LED lighting integrated chips on lamp housings. With the integration method and the LED lighting integrated chip, production processes and cost of the LED lighting lamps can be greatly reduced, and industrialization of LED energy-saving lighting products is benefited.

Description

technical field [0001] The invention relates to an integration method of an LED lighting circuit and an LED lighting integrated chip, belonging to the technical field of LED lighting. Background technique [0002] LED light-emitting diode lighting has the advantages of high efficiency and energy saving. The luminous efficiency of most current LED lighting lamps can exceed 70LM / W, which is more energy-saving than traditional energy-saving lamps. Theoretically, the luminous efficiency of green LEDs can be as high as 683LM / W; the theoretical efficiency of white LEDs can also reach 182.45LM / W, so there is huge room for improving LED lighting efficiency. [0003] In the current LED lamp design, the LED chip is packaged into an independent chip module, and the bridge rectifier, rectifier diode, constant current diode, etc. are also packaged into independent components. The lamp manufacturer first integrates these independent components The device is integrated on the circuit boar...
