METHOD AND DEVICE FOR CONSTRUCTING HIGH-POWER LED LIGHTING FIXTURE
A method and a device for constructing a high-power LED lighting fixture are disclosed, wherein a high-power LED lighting fixture is constructed by assembling one or more LED lamp heads with a standard interface, in which an LED optical module and an independent driving power source are integrated, onto a lamp base (15). This method can shorten the production process of the LED lighting fixture, and improve its mass productivity.
Proposed are a method and apparatus for LED lighting, a method for improving LED luminous efficiency, and a method for integrating an LED lighting circuit and an integrated chip therefor, which use the negative power feature of the constant current diode (CRD) to enable the power supply current to drive the LED to emit light and illuminate after the constant current effect of the constant current diode (CRD). The constant current diode (CRD) and an LED light module are encapsulated and integrated into one chip to form an LED light module integrated chip. The constant current diode (CRD) is characterized by negative power, which enables the LED light module integrated chip to have the physical feature of negative power, and when the operating temperature of the whole LED integrated chip becomes too high, the constant current diode (CRD) will automatically reduce the power input to the circuit, so as to lower the temperature of the LED light module integrated chip, thus protecting the LED light module integrated chip and avoiding the problem of light attenuation due to overheating of the LED.
