The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail:
Referring to accompanying drawing 1 to shown in accompanying drawing 3, the air that utilizes described in the present embodiment flows freely the LED candle lamp of heat radiation from bottom to top, it includes Lamp cup 1, LED lamp pearl 2, heating column 3, upper spacer 6, metal lower clapboard 7, candle shape lampshade 4 and FPC 5, LED lamp pearl 2 is located on FPC 5, and this FPC 5 is close to heating column 3 surfaces, there is groove position Lamp cup 1 inside, the fixed placement LED power supply 8 corresponding with groove position on groove position, the tubular structure that heating column 3 is up/down perforation, upper spacer 6 is provided with air vent 601, metal lower clapboard 7 is provided with lower air vent 701, the tubular structure that described heating column 3 is up/down perforation, the upper air vent 601 of upper spacer 6 mates assembling with heating column 3 upper port, the lower air vent 701 of metal lower clapboard 7 mates assembling with the lower port of heating column 3, on 4 times edges of candle shape lampshade and Lamp cup 1 along fixing assembling, cup at Lamp cup 1 is provided with multiple fresh air inlets 101 with it, at the cover body of candle shape lampshade 4, be provided with multiple exhaust vents 401, wherein in the upper end of candle shape lampshade 4, offer exhaust vent 401 for best, fresh air inlet 101, lower air vent 701, heating column, exhaust vent 401 on lower air vent 601 and candle shape lampshade 4 forms aeration radiation system, air flows freely from bottom to up in this system.Except necessary lamp holder, the Lamp cup 1 of composition LED candle lamp housing main body and the material of candle shape lampshade 4 are the non-conducting material strong every power, and the upper spacer 6 that plastic material is made in candle shape lampshade 4 and the position buckle that is positioned at exhaust vent 401 downstreams fix, described heating column 3,7 of metal lower clapboards are collected heat by having, are promoted the metal material manufacture of Air Flow effect to form.
And in normal circumstances, LED candle lamp is all that light source at right angle setting is used, therefore according to the Structural Tectonics of above-mentioned LED candle lamp, can reach the effect of quick heat radiating: when this LED candle lamp work, LED light source will produce heat, and metal metal lower clapboard 7 and heating column 3 can be collected a large amount of heats, known according to thermodynamic principles, heat all flows from bottom to up, therefore heat is successively by the lower air vent 701 of metal lower clapboard 7, the heating column 3 of up/down perforation tubular structure, exhaust vent 401 on the upper air vent 601 of upper spacer 6 and candle shape lampshade 4 distributes, cold wind can enter this LED candle lamp inside from 1 glass of Lamp cup fresh air inlet 101 with it, thereby realize natural convection air, by flowing of inside and outside air, can take away the heat that LED lamp 2 produces, greatly increase the radiating rate of light fixture, improve the radiating effect of light fixture.The upper spacer 6 being provided with in heating column 3 top and bottom and metal lower clapboard 7 are separated heat flow space and LED light-emitting area space completely, heat is from the heating column internal flow of up/down perforation tubular structure, heat is more intensively circulated, further accelerate dissipation of heat speed, and because metal has heat build-up effect, and according to the cold and hot convective principles of air, metal lower clapboard 7 can be collected heat effectively, and more effectively accelerate Air Flow.Simultaneously, because upper spacer 6 is made for plastics, the light that LED lamp sends also can see through upper spacer 6, make this lamp body upper end can distribute light, and this upper spacer 6 can also prevent that dust from entering LED light-emitting area space effectively, stopped dust enter LED light-emitting area space and be attached to LED lamp pearl 2 and candle shape lampshade 4 inwalls on situation, in addition, the housing main body forming due to Lamp cup 1 and candle shape lampshade 4 all adopts non-conducting material manufacture, possess good in power, avoided the danger of the easy electric shock that the metal shell design of traditional LED candle lamp brings, simultaneously, the all right high non-isolation drive power supply of efficiency of selection, improved the luminous efficiency of LED, caloric value during due to non-isolation drive power work is very low, can exert an influence to product heating hardly, the heat of this LED candle lamp entirety is further reduced, also easily process electromagnetic interference problem.This LED candle lamp structure is simple, and easy dissembling and-assembling has splendid radiating effect, can effectively improve the operating efficiency of LED lamp, the service life of prolongation light fixture.
The examples of implementation of the above are only the preferred embodiment of utility model, not with this, limit practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
