Abstract

The invention discloses a PAR30S type LED (light-emitting diode) spotlight, which comprises a lens fixing ring, a lens, a screw, a lens fixing seat, an LED, a heat radiation seat, a heat radiation shell, an insulating fixing seat, a drive power supply, a connecting element and a lamp holder. The PAR30S type LED spotlight is characterized in that the lens fixing ring and the lens fixing seat are connected through fasteners, the heat radiation seat is embedded in the heat radiation shell through interference fit of the top of the heat radiation seat and the heat radiation shell, the side wall of the heat radiation seat is provided with a plurality of longitudinal heat radiation through holes, the outer side of the heat radiation seat is provided with a plurality of heat radiation ribs, the heat radiation shell is internally provided with heat radiation inner grooves, and the bottom of the heat radiation shell is provided with a hollowed ventilated groove. An annular ventilated inlet, the heat radiation through holes, the heat radiation inner grooves, the hollowed ventilated groove and circular-arc-shaped longitudinal through grooves of the spotlight disclosed by the invention are communicated with one another sequentially to form a longitudinal heat radiation passage; heat generated by the drive power supply and the LED can be quickly and upwards guided out by the vertical air convection design according to the physical phenomena that upper air is hot and lower air is cold.

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, and more specifically a PAR30S 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 ...
