Abstract

The utility model belongs to an LED lamp, in particular to a ceramic LED reflector lamp, which comprises a lamp holder, a lens and a radiating body and is characterized in that the radiating body comprises radiating through holes. The radiating structure not only has large radiating area but also has a plurality of through holes from top to bottom, and the plurality of through holes can also be called 'air flues' and can greatly improve radiating efficiency.

Description

A kind of LED shot-light

Technical field

The utility model belongs to the LED light fixture, relates in particular to a kind of ceramic LED shot-light.

Background technology

Existing LED pottery shot-light; Be smooth surface or open some simple groove or stripeds, very limited to the lifting of area of dissipation, and radiating efficiency is directly proportional with area of dissipation; So radiating efficiency is low; Led light source produces a large amount of heat energy in luminous process, these heat energy can not get distributing timely and can make the temperature of LED lamp significantly rise, thereby directly influences the service life of shot-light.As shown in Figure 4, some simple groove or stripeds are just opened in the radiator surface, and area of dissipation is little.

Summary of the invention

Little in order to overcome existing LED pottery shot-light area of dissipation; The deficiency that radiating efficiency is low; The utility model provides a kind of special radiator structure, and this radiator structure not only area of dissipation is big, and has many top-down through holes; Also can be called " air channel ", can significantly improve radiating efficiency.

A kind of LED shot-light comprises lamp holder, lens and radiator, it is characterized in that said radiator comprises equally distributed heat radiation through hole.

Said heat radiation through hole is made up of the vertical cambered surface that links to each other of interlocking in twos.

Said radiator is the ceramic heat-dissipating body.

The special radiator structure that the utility model solves heat dissipation problem is: the blade of spreader surface adopts staggered in twos vertical cambered surface; On be regarded as intersection one by one; Be connected with each other again between the intersection, form type heat radiation grid of floweriness shape, comprise a lot of types of triangles, four jiaos heat radiation through hole.These staggered radiator shutter designs have increased area of dissipation greatly on the one hand, and on the other hand, this radiator has many heat radiation through holes; I.e. " air channel " design, when heat passed to spreader surface, the temperature in the through hole raise; Thereby air pressure is changed; The generation air flows, and takes away heat in large quantities, improves radiating efficiency dramatically.

Fig. 4 is the structural representation of traditional ceramics shot-light.

Among the figure: 1 is ceramic lamp base, and 11 is the MR16 standard interface, and 12 is hickey; 2 is power supply; 3 is radiator, and 31 is hickey, and 32 for placing the platform of pcb board, and 33 is the groove of fixed lens; 4 is pcb board, and 41 is aluminium base, and 42 is LED lamp pearl; 5 is lens, and 51 is the lens end opening, and 52 is the lens top edge.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further description.

Ceramic LED shot-light shown in Figure 1 comprises ceramic lamp base, lens, pcb board, power supply, base and radiator, and ceramic lamp base 1 passes through hickey 12 and 31 turn-knob matching and fixing with radiator 3.In the space between power supply 2 rotations and ceramic lamp base 1 and the radiator 3.

Lens 5 are processed for the optics acrylic, accomplish the optics luminous intensity distribution to LED lamp pearl 42 through Specialty Design, and the light that makes lamp is with certain angle outgoing.Lens 5 scioptics top edges 52 engage with the groove 33 of radiator 3, and use that mono-component organic silicone is gluing to be connect fixingly, and lens end opening 51 just in time engages with lamp pearl 42, to reach the requirement of luminous intensity distribution.

Pcb board 4 is positioned on the solid platform 3.2 of radiator 3, and uses heat conductive silica gel to fix.

Fig. 2 and Fig. 3 are respectively radiator upward view and the vertical view of the utility model embodiment.As shown in the figure, the blade of spreader surface adopts staggered in twos vertical cambered surface, on be regarded as intersection one by one, be connected with each other again between the intersection, form type heat radiation grid of floweriness shape, comprise a lot of types of triangles, tetragonal heat radiation through hole.Shown in Figure 3 like Fig. 2 in the present embodiment is 12 inner ring class triangle deep via, 12 tetragonal moderate depth through holes of centre circle class, 12 shallow through holes of outer ring class triangle.

Should be pointed out that the utility model not only is confined to the foregoing description, the LED shot-light that every employing has an above-mentioned heat radiation via design ceramic heat-dissipating body all should be thought the protection domain that falls into the utility model.

Claims
