The utility model discloses a high-efficiency and heat-radiation type LED cup lamp which comprises a lamp cover, a lamp cup and a lamp holder, wherein a power wire is arranged in the lamp holder, the lamp cup is arranged on the lamp holder, and the lamp cover is arranged on the lamp cup. The high-efficiency and heat-radiation type LED cup lamp is characterized by comprising a drive circuit board holding cavity and heat radiating fins, wherein the drive circuit board holding cavity and the heat radiating fins are made of plastics and heat conduction glue and integrally moulded in a compression manner, a columnar metal heat conduction member is arranged in the drive circuit board holding cavity, the end part of the metal heat conduction member protrudes out of an opening of the drive circuit board holding cavity, a substrate is arranged on the end part of the metal heat conduction member, LED beads are arranged on the substrate, and a drive circuit is arranged in the metal heat conduction member. The LED cup lamp has the advantages of good heat conduction property and high safety because the lamp cup is made of the plastics and the heat conduction glue, reduced light energy loss because the metal heat conduction member is arranged in the drive circuit board holding cavity and the end part of the metal heat conduction member protrudes out of the opening of the drive circuit board holding cavity to ensure that heat generated by an LED light source is rapidly transmitted, enlarged light emitting angle, and uniformity in light efficiency.
Description
Technical field
The utility model relates to LED lamp technical field, particularly a kind of high efficiency and heat radiation, even, the safe high-efficient heat-dissipating LED cup lamp of light efficiency.
Background technology
The LED lamp well becomes the development trend of lighting engineering owing to its energy-saving effect.Yet high-power LED bulb or shot-light that existing LED lamp particularly surpasses 1W produce a large amount of heats when illumination, cause easily producing high temperature in the LED lamp, if the radiating treatment of LED lamp is bad, can't stably throw light on, and cause easily the product premature failure.The high-power LED bulb of selling on the existing market or shot-light series mostly adopt the way of die casting aluminium and the heat radiation of ADC12 radiating seat, being about to led chip is installed in the radiating seat, fin by means of the radiating seat periphery is gone out dissipation of heat, yet, existing radiating seat radiating effect is undesirable, and can bring potential safety hazard, in case there is inner lead to touch lamp housing, consequence is with hardly imaginable.Can not reach application requirements, need to further improve.
At present, the producer of many application facet is all thinking hard greatly for the heat dissipation problem that solves LED.Wherein, be a kind of LED light fixture Lamp cup of CN201265843 and the utility model patent that uses the LED light fixture of this Lamp cup in patent publication No., this Lamp cup includes radiating element, in radiating element, be provided with LE D light source container cavity and drive circuit board container cavity, outer surface at radiating element is provided with a plurality of fin, and radiating element and fin are molded by high heat conductive insulating plastics Integral mold.Although patent is considered the heat dissipation problem of LED, led light source container cavity and drive circuit board container cavity are in radiating element, and Lamp cup has adopted the high heat conductive insulating plastics, and this structure can not effectively utilize light, have limited brightness and the scope of application of light fixture.
Summary of the invention
The utility model provides that a kind of light efficiency is even, light, the high-efficient heat-dissipating LED cup lamp of safety, high-efficient heat-dissipating.
