Technical field
The present invention relates to LED.
Background technology
Along with the development of LED, known dawn gradually.LED compares advantages such as having life-span length, energy-saving and environmental protection with ordinary lamps, is valued by Ge great small enterprise.But high with regard to its making side's cost, cause that it enters slowing of average family.LED in use can generate heat, and as left not in time, the service life of LED can be largely effected on by heat, so the radiating piece of LED is typically with aluminum.As depicted in figs. 1 and 2, LED is generally steeped 5 by glass, Lamp cup 1, connector 2, lamp holder 3 forms, wherein Lamp cup oral area is provided with dissipating cover 4, dissipating cover 4 is provided with luminous electric elements 42, by connector 2 Lamp cup 1 it is connected with lamp holder 3 and fixes, its main radiating mode is the fin 10 arranged on Lamp cup 1 outer wall, and the current common process of Lamp cup is to adopt the mode of pressure injection and machining to make, namely after aluminum liquefied by pressure injection equipment pressure injection to molding in Die, adopting the drawback come in this way is that cost of manufacture is high, production efficiency is low, and radiating effect is also unsatisfactory.
Summary of the invention
The technical problem to be solved just there is provided a kind of LED ventilation and heat structure, simplifies structure, reduces cost, improves radiating effect.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that a kind of LED ventilation and heat structure, Lamp cup including aluminum, it is connected with lamp holder by connector bottom Lamp cup, it is provided with thermovent between Lamp cup bottom opening and connector, thermovent and Lamp cup inner space, a circle internal projecting ring it is provided with inside Lamp cup bottom opening, internal projecting ring is circumferentially arranged with crenel groove, forming thermovent between crenel groove and connector cylinder outer wall, outer bulge loop is circumferentially evenly arranged with two boss raised up and snaps in crenel groove.
Preferably, described connector includes cylinder, and cylinder bottom is provided with the outer bulge loop of a circle, is provided with lower heat radiation gap between outer bulge loop and Lamp cup bottom surface, and outer bulge loop is connected with threaded portion and is connected with lamp holder.
Preferably, described cylinder has been evenly distributed two hollow circuit cylinders, hollow circuit cylinder and 90 degree circumferentially-adjacent of boss interval, hollow circuit cylinder is vertically arranged, hollow circuit cylinder bottom extends to outer bulge loop, top protrudes from the oral area of cylinder and extends to immediately below side opening, and internal projecting ring correspondence hollow circuit cylinder is provided with arc neck.
Preferably, described Lamp cup is stamped and formed out round platform tubular construction by the aluminium strip of banding.
The present invention is provided with thermovent between Lamp cup bottom opening and connector, thermovent forms the heat dissipation channel for air flowing with Lamp cup inner space, additionally, the Lamp cup of aluminum itself has the effect of heat radiation, thus invention adopts the mode that cross-ventilation and metal heat absorption combine, guaranteeing that heat is discharged, radiating effect is greatly improved.And the aluminium strip punch forming that the Lamp cup of this LED is by banding, Lamp cup is connected with lamp holder and fixes by connector, and manufacture method is simple, and efficiency is high, makes the cost of LED be decreased obviously.
