The invention is applied to the field of light-emitting diode (LED) lighting and provides an LED connection circuit and a fixed explosion-proof lamp. An embodiment of the LED connection circuit utilizes an LED connection method which is simple, low in cost and practical. When an LED is normal, the luminescence is stable. When short circuit, open circuit and the like happen, effects on luminescence and service life of other LEDs are avoided. The connection method is reliable. Due to the fact that current and voltage are neither high, a driving circuit is easy to design and low in cost. In addition, the connection method can be expanded, is suitable for large-power LED lamps in explosion places, is balanced in output voltage and current and is easy to design driving voltage.
Description
technical field [0001] The invention belongs to the field of LED lighting, in particular to an LED connection circuit and a fixed explosion-proof lamp. Background technique [0002] At present, energy-saving lamps have become the mainstream and will be the future development trend. LED light sources have been widely used in landscape lighting, street lamps, explosion-proof lamps and other places. LED (Light-Emitting-Diode is a light-emitting diode) is a semiconductor that can convert electrical energy into visible light. It changes the principle of incandescent lamp tungsten filament luminescence and energy-saving lamp trichrome luminescence, and uses electric field luminescence. According to the analysis, the characteristics of LED are very obvious, such as long life, high luminous efficiency, no radiation and low power consumption. [0003] When using LED lighting, the first thing to consider is the light efficiency, brightness, life and cost of LED. Since the main reaso...
