Description

Multipoint mode LED Projecting Lamp

Technical field

The utility model relates to a kind of multipoint mode LED Projecting Lamp that outdoor lighting is used that is used for.

Background technology

In recent years, the LED outside light is as the novel illumination light fixture, because it has long-life, low in power consumption, the outer lighting of increasing conventional chamber is replaced by the LED outside light.But because the LED outdoor lamp is perfect inadequately on heat dissipation design, the outdoor application environment is more changeable in addition simultaneously, directly cause the heat of led light source node too high, can't effectively be transmitted to the external world, directly cause light decay serious, make the long-life characteristics of led light source have a greatly reduced quality.Simultaneously also rarely take power supply heat sinking into account, can not guarantee the useful life of power supply.

Summary of the invention

In view of the problem that prior art exists, the utility model provides a kind of multipoint mode LED Projecting Lamp.This Projecting Lamp adopts monomer light source dot matrix to distribute, and makes uniform heat distribution, improves radiating efficiency, and the bilayer heat radiation one project organization of light source and power supply makes between two heat dissipating layers, forms 6 chamber air channels.Chamber is inboard to adopt the design of wave lines, increases the contact area with air, forms in the middle airtight chamber in structure simultaneously and places power supply.

The utility model for achieving the above object, the technical scheme of being taked is: a kind of multipoint mode LED Projecting Lamp, it is characterized in that: comprise screw, strip of paper used for sealing, transparent acrylic board, lens, lens mount, the LED lamp, rubber strip, pcb board, radiator and driving power, several described LED lamps are welded on the pcb board, the groove spiral-lock that several lens mounts are provided with by its rear end is on the LED lamp, lens mount and pcb board (3) are adhesively fixed, several lens tightly are stuck in respectively in the preceding end slot of lens mount, pcb board places the groove that scribbles insulating heat-conductive coating in the radiator planar ends chamber, pcb board and radiator fix, the circle semicircle groove that described rubber strip places radiator planar ends right angle mouth to be provided with, described transparent acrylic board places on the right angle mouth, pass through strip of paper used for sealing, screw and radiator are fixed together, described driving power is fixed in the radiator arc tips chamber, and the end face of driving power one end amplexiforms with the chamber wall that scribbles insulating heat-conductive coating.

The beneficial effect that the utility model produced is: realize light source and both efficiently radiates heats of power supply.Reach of the damage of extraneous adverse circumstances such as waterproof simultaneously to power supply.

The specific embodiment

As Fig. 1,2, the LED of multipoint mode shown in 3 Projecting Lamp, several LED lamps 6 are welded on the pcb board 8, the groove spiral-lock that several lens mounts 5 are provided with by its rear end is on LED lamp 6, lens mount 5 is adhesively fixed with pcb board 8, several lens 4 tightly are stuck in respectively in the lens mount 5 preceding end slots, pcb board 8 places the groove 9-1 that scribbles insulating heat-conductive coating in the radiator 9 planar ends chambers, pcb board 8 fixes by screw and radiator 9, the circle semicircle groove 9-3 that described rubber strip 7 places radiator 9 planar ends right angle mouth 9-2 to be provided with, described transparent acrylic board 3 places on the right angle mouth 9-2, by strip of paper used for sealing 2, screw 1 is fixed together with radiator 9, described driving power 10 is fixed on by screw in the arc tips chamber of radiator 9, and the end face of driving power 10 1 ends amplexiforms with the chamber wall that scribbles insulating heat-conductive coating.

Rubber strip 7 is squeezed in transparent acrylic board 3 and radiator 9 in the middle of both, forms airtight chamber, to reach waterproof, the dustproof purpose.

Lens mount 5 plays the purpose of fixed lens 4, becomes one lens 4, lens mount 5, LED lamp 6, pcb board 8 four one-tenth as a whole being placed in the chamber to guarantee LED lamp 6 and lens 4.Radiator 9 minutes is inside and outside up and down two-layer, internal layer promptly with pcb board 8 under insulating heat-conductive coating contact layer, radiating ribs different in size is arranged below, main being responsible for to 6 heat radiations of LED lamp, the long radiating ribs of the six roots of sensation is wherein arranged, link to each other with lower floor arc heat dissipating layer, and isolate seven chambers.In seven chambers, middle chamber rear and front end sealing forms the airtight chamber of cuboid, and driving power 10 is placed in this chamber, is fixed on radiator 9 skins by screw.Six remaining chamber two ends are not all sealed, so that form the air channel.Efficiently radiates heat.

Whole radiator structure is: the heat of the generation when LED lamp 6 is lighted is heat sink by lamp pearl bottom, derives through radiator 9 internal layers through pcb board 8, by the radiating ribs on upper strata heat is loose in formation air channel on the one hand, is taken away by the mobile of air; Conduct to outer heat radiation by radiating ribs on the other hand; The heat that driving power 10 is produced is directly by radiator 9 outer derivation, and skin not only can also can be given the hot-air heat radiation in the middle air channel simultaneously to power supply heat sinking.Thereby reach whole effective heat radiation.LED lamp 6 and driving power 10 are placed on heat dissipating layer respectively isolates in the chamber of formed independent sealing, has effectively protected the core of LED Projecting Lamp.Thereby guarantee the higher degree of protection of whole light fixture.
