The invention discloses a PAR38 light-emitting diode (LED) spotlight which comprises a lens fixing ring, a lens, screws, a lens fixing seat, an LED, a cooling seat, a cooling casing, a driver cover, a driving power source, a connection part and a light base. The PAR38 LED spotlight is characterized in that the cooling seat is embedded in the cooling casing through clearance fit of the top of the cooling seat, longitudinal cooling through holes are formed in the lateral wall of the cooling seat, and cooling ribs are arranged on the outer side of the cooling seat; radial cooling ribs are arranged in the cooling casing, and hollow-out ventilation grooves of cooling inner grooves are communicated with each other and arranged at the bottom of the cooling casing. According to the PAR38 LED spotlight, an annular ventilation inlet at the top end of the cooling seat, the cooling through holes in the lateral wall of the cooling seat, the cooling inner grooves in the cooling casing, the hollow-out ventilation grooves at the bottom and an arc longitudinal through groove on the connection part are communicated in sequence to form a longitudinal cooling channel. By means of the physical phenomenon that upper air is hotter than lower air, heat energy generated by the driving power source and the LED can be quickly guided out upwards due to the convection of the upper air and the lower air.
Description
technical field [0001] The invention relates to the field of LED lamps, in particular to an LED lamp that meets the requirements of the American Energy Star, specifically an LED lamp that can meet the requirements of UL safety regulations and the American Energy Star, more specifically a PAR30 The latest LED spotlights can be widely used in various places and scopes. Background technique [0002] In today's society, the demand for energy-saving and environmentally-friendly products is becoming more and more urgent. LED light source products are widely used due to their energy-saving and environmental-friendly characteristics, and the market demand is increasing. But at present, LED light sources and lamps have fatal shortcomings of high junction temperature and serious light decay. It is one of the problems hindering the development of LED lighting products. Therefore, the design of high luminous efficiency of LED lighting products and advanced LED cooling system has becom...
