Description
Technical field
The utility model relates to lighting field, further, relates to a kind of LED shot-light structure with good heat radiating function.
Background technology
It is general day by day that LED is applied to lighting field, but because the characteristic of LED itself and the restriction of manufacturing process, the heat dissipation problem of LED light fixture is the difficult problem that people are devoted to solve always.In much with the illuminating lamp of LED, because the design reasons of fitting structure does not realize well dispelling the heat, so that influenced the service life of light fixture as light source.The great power LED shot-light should solve heat dissipation problem, is subjected to the restriction of light fixture size, volume again, also will consider the requirement of its use occasion to distribution of light, therefore, the appropriate design of its structure is seemed particularly important.Patent CN200620057928.4 discloses the colorful Color-changing lamp of a kind of great power LED, it adopts two pcb boards, wherein a LED lamp plate is placed in the lamp body cavity, and another block power supply drive plate is installed in the lamp holder cavity, is separated by the lamp body bottom between two pcb boards.Though the heat that this structure makes led light source produce distributes by the heat radiation lamp body that is in contact with it, but the power drives plate is owing to be wrapped in the lamp holder cavity of narrow and small and sealing, and make as easy as rolling off a log being burnt out of components and parts on the power drives plate, can burn out cap part when serious and cause danger.
The utility model content
At the technical problem of above-mentioned existence, the utility model provides a kind of great power LED shot-light, effectively solves the heat dissipation problem of led light source and electronic devices and components, prolong the service life of LED light fixture, and production technology is simple.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of great power LED shot-light, comprise lamp holder and connected lamp body, lamp body is hollow structure, its inboard port is provided with a platform, place wiring board on the platform, the light fixture light-emitting window is covered with an optical lens, and described wiring board comprises led light source and power driving circuit, offer several heavy copper vias in the position that mounts led light source on the wiring board, the copper that layer of surface is handled through insulating oxide is laid in the zone of negation element device side outside the conducting wire of wiring board.
The outer wall of described lamp body is provided with radiating fin.
Described platform simultaneously is being provided with a series of radiation tooths back to the lamp body cavity, and described lamp holder is a cavity structure, and the lamp holder outer wall offers some air vents, and when lamp holder was connected with lamp body, described radiation tooth was positioned at described cavity structure.
Described optical lens comprises luminous intensity distribution portion and installation portion.
Described luminous intensity distribution portion covers on the top of led light source.
Described installation portion is the planar annular of lens upper surface except that luminous intensity distribution portion.
The beneficial effect that technical solutions of the utility model are brought:
LED lamp plate in the LED shot-light and power drives plate are united two into one, and this wiring board that unites two into one done some processing on technology, be specially: a lot of heavy copper vias are set mounting the led light source place, so that the heat sink welding of LED is in the circuit board the time, scolding tin fills up through hole, the platform of contact lamp body radiator.Lay the copper layer in the bottom surface of wiring board, because the good heat conductive characteristic of copper, make the heat that produces on led light source and the electronic devices and components distribute by the platform of the lamp body radiator that contacts with wiring board.Platform simultaneously is being provided with a series of radiation tooths back to the lamp body cavity, when this radiation tooth assembles at the lamp holder lamp body, just in time is installed in the cavity structure of lamp holder, outwards dispels the heat by several air vents of offering at the lamp holder outer wall, further improves radiating efficiency.Simultaneously, because power driving circuit is installed in the lamp body inner chamber body, space compared with the lamp holder cavity is a lot of greatly, like this, thereby the electronic devices and components on the power driving circuit are because installing space no longer limits very big choice to its size, can select functionally, the electronic devices and components of safety and reliability further guarantee the operate as normal of power supply.
Optical lens comprises installation portion and luminous intensity distribution portion, and this structure is convenient to production and assembly.
