Abstract

The utility model relates to a high-power LED spot lamp with high-efficiency radiation, comprising a high-power LED, a heat sink, an aluminum baseplate, a light reflecting cup, a spiral coil and a lens. The upper top surface of the heat sink is provided with screw holes used for installing the aluminum baseplate; after the high-power LED is welded on the aluminum baseplate, the aluminum baseplate can be tightly locked by screws to cling to the upper top surface of the heat sink; protrudent screw threads are arranged around the inner side below the cavity wall of the heat sink so as to enable the spiral coil to be screwed in and locked, in this way, the lens is fixed; and the edge of the upper part of the lens is in a plane shape, so the lens can be tightly clamped in the heat sink by the spiral coil.

Description

The great power LED shot-light of high efficiency and heat radiation

Technical field

The utility model relates to the great power LED shot-light heat dissipation technology field in lamp outer casing attractive in appearance and heat dissipation technology field, particularly high efficiency and heat radiation.

Background technology

Led light source is driven by power source special, has constant current, stable, characteristics of high efficiency, and the heat dissipation problem of LED shot-light is one of reason that it can not extensive use at present.LED inevitably can produce some heats when converting electric energy to luminous energy, power is big more, and brightness is high more, and the heat of generation is just many more.If heat does not distribute, too high temperature not only can influence the stable of power supply, and can quicken the decay of LED brightness, and then shortens the service life of LED.The problem that LED shot-light ubiquity outward appearance is coarse, temperature is too high has in the market limited the brightness of light fixture, influences service life.

The utility model content

The utility model comprises great power LED, radiator, aluminium base, reflector, spiral coil, lens, the last end face of described radiator has screw hole, is used to install aluminium base, after great power LED is welded on the aluminium base, described aluminium base can be close to the last end face of radiator by screw lock jail; Around the chamber wall below of radiator is inboard outstanding screw thread is arranged, can make the spiral coil precession and be locked, lens are fixed with this; Described lens top edge is plane, can be clamped in the described radiator by spiral coil when assembling

The specific embodiment

As shown in Figure 1, be the perspective view of LED shot-light, the great power LED shot-light of high efficiency and heat radiation comprises great power LED 2, radiator 3, aluminium base 4, reflector 5, spiral coil 6, lens 7.See for clear, do not provide cover characteristics among Fig. 1.Great power LED 2 is welded on the aluminium base 4, and great power LED 2 and aluminium base 4 adopt common design.The great power LED shot-light of the high efficiency and heat radiation that assembling is finished as shown in Figure 7.

Fig. 2 is the schematic diagram of radiator 3, and Fig. 3 is the upward view of radiator 3: around walls below, radiator 3 chamber is inboard outstanding screw thread is arranged, can make spiral coil 6 precessions and being locked, and with this that lens 7 are fixing.The last end face of radiator 3 has screw hole 31, is used to install aluminium base 4, and after great power LED 2 was welded on the aluminium base 4, aluminium base 4 can be close to the last end face of radiator 3 by screw lock jail, and contact-making surface scribbles heat-conducting silicone grease, to strengthen heat-conducting effect; In order to strengthen the contact area of radiator 3 and air, it is 0.3 millimeter fin 32 that radiator 3 outer wall circumference are distributed with 72 thickness equably, in order to strengthen the capacity of heat transmission, per two fin, 32 root disjunctors become one group to link to each other with the chamber wall of radiator 3, fin 32 distribution gaps have 1.8 millimeters, can prevent that finger or big thing from sandwiching; Fin 32 lower limbs process circular chamfering, guarantee safe in utilization.

Fig. 4 is reflector 5 schematic diagrames.In the present embodiment, reflector 5 is made for white high temperature fire prevention PC material, and reflection angle belongs to common design.

Fig. 5 is the schematic diagram of spiral coil 6, and there is screw thread in spiral coil 6 outsides, can be rotated to lock inboard, wall below, radiator 3 chamber, simultaneously lens 7 is snapped in and is fixed in the radiator 3; The position that spiral coil 6 is locked is in radiator 3 central authorities, belongs to three-dimensional embedded mode; Spiral coil 6 outer surfaces have the draw-in groove of two symmetrical distributions, and draw-in groove concaves, and when assembling or dismounting spiral coil 6, available clip or tweezers insert in the draw-in groove, rotation clip or tweezers, thereby rotatable spiral coil 6.

Fig. 6 is the side view of lens 7, and lens 7 top edge are plane, can be tightened by spiral coil 6 when assembling, thereby be fixed in the radiator 3.Lens 7 adopt the optics acrylic material, and structure adopts common optical design; After reflector 5 reflections, the light beam of scioptics 7, its beam angle is amplified in proportion by lens 7.

Above content be in conjunction with concrete embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
