Description
Technical field
The utility model relates to LED lamp technical field, the LED cup lamp of particularly a kind ofly be convenient to dispel the heat, light efficiency is even, safe.
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.
At present, the producer of many application facet is all thinking hard greatly for the heat dissipation problem that solves LED.Wherein, be that this bulb mainly comprises lampshade, Lamp cup and lamp holder, and power supply is set in the lamp holder in a kind of patent of utility model of LED bulb of high efficiency and heat radiation of CN201844274U in patent publication No.; Lamp cup is installed on the lamp holder, pcb board is set in the Lamp cup, Transparent lamp shade is installed on the Lamp cup, inwall and the outer of Lamp cup are provided with fin, and this fin is arranged to whirlwind type along inwall and the outer array of Lamp cup; One plastic rubber connector is set between lamp holder and the Lamp cup, and this plastic rubber connector is threaded with the Lamp cup utilization, and Transparent lamp shade is the transparent PC lampshade of light diffused optical grade, and this PC lampshade is threaded with described Lamp cup.LED bulb behind the employing such scheme, at first the Lamp cup inwall of aluminum alloy material and outer all arrange the design of cyclone radiating fins, and the drain pan that contacts with pcb board of thickening, more be conducive to the heat radiation of LED bulb, solved the bad problem of existing LED bulb heat radiation, secondly the light diffused PC lampshade of optical grade has good translucent effect, and be not easy fragmentation, but this structure can not quick heat radiating, light effects and security performance do not reach application requirements, need to improve as further improvement of the utility model.
Summary of the invention
The utility model provides a kind of contour structures attractive in appearance, light efficiency evenly, safely, the LED cup lamp being convenient to dispel the heat.
The technical solution of the utility model is as follows: a kind of LED cup lamp, comprise lampshade, Lamp cup and lamp holder, be provided with power line in the lamp holder, Lamp cup is installed on the lamp holder, lampshade is installed on the Lamp cup, it is characterized in that: described Lamp cup comprises drive circuit board container cavity and fin, drive circuit board container cavity and fin are molded by the aluminium alloy Integral mold, the a plurality of vertical arrays of described fin are in drive circuit board container cavity outer surface, fin top is wider than the fin bottom and is formed the U font groove, can accelerate to fall apart, fin is whole very attractive in appearance such as the chrysanthemum profile; Be provided with the cylindricality metal heat-conducting piece in the drive circuit board container cavity, metal heat-conducting piece is equipped with substrate on the end, and substrate is provided with LED lamp pearl, described LED lamp pearl is distributed on the substrate by two-layer circular array, the LED lamp pearl of two-layer circular array is crisscross arranged, and lighting angle is enlarged, and light efficiency is even.
As further improvement of the utility model, described substrate is fixed on the metal heat-conducting piece end by three screws, be provided with drive circuit board in the metal heat-conducting piece, the metal heat-conducting piece good heat conductivity, the heat that drive circuit board sends can fast transport to metal heat-conducting piece, through the fin heat radiation, the LED lamp can be worked in the temperature that requires.
As further improvement of the utility model, described lamp holder and metal heat-conducting piece knot mouthful place's inwall is provided with the isolation plastic parts, has increased security performance.
Described lampshade is that the transparent PC plastics of optical grade are made, and has good light transmission effect.
The beneficial effects of the utility model are: simple in structure, the good looking appearance of the utility model, and translucent effect is good, and light efficiency is even, uses simultaneously safety, area of dissipation is large, heat dissipation capacity is high, can improve LED lamp operating efficiency and service life.
