Description
Technical field
The present invention is relevant for a kind of light fixture, especially a kind of can be by the heat radiation module that radiator and radiator fan constituted, in order to the light fixture that dispels the heat to power supply circuit board.
Background technology
Please with reference to shown in Figure 1, existing light fixture 8 roughly comprises one first shell 81, one second shell 82, a radiator 83, a radiator fan 84, a circuit board 85 and a light-emitting component 86.This first shell 81 can be each other to group with this second shell 82, and to constitute a hollow housing, wherein this first shell 81 is provided with several air inlets 811, and this second shell 82 is provided with several air outlets 821; Again; It is inner that this radiator 83, radiator fan 84, circuit board 85 and light-emitting component 86 are fixed in this hollow housing; Wherein this radiator fan 84 combines this radiator 83, and this light-emitting component 86 amplexiforms the side in this radiator 83, and 85 of this circuit boards electrically connect this light-emitting component 86.
Should have light fixture 8 now when reality is used; It is the lamp socket that is connected in like wall, ceiling or the first-class place of table; So that form electric connection through this lamp socket and general electric power system; And then utilize this circuit board 85 to make 86 energisings of this light-emitting component produce light, and light is projected to the external world via this second shell 82.In addition, when this light-emitting component 86 produces thermal source because of energising,, and cooperate the water conservancy diversion start of this radiator fan 84, to provide this light-emitting component 86 predetermined radiating effect, so can prolong the service life of this existing light fixture 8 then by the conduction of heat of this radiator 83.
Above-mentioned existing light fixture 8 forms several fixed legs 812 in the inboard perisporium of this first shell 81 in addition, and utilizes several screws 87 that this circuit board 85 is locked in respectively this fixed leg 812, so can really this circuit board 85 be fixed in this first shell, 81 inboards; Yet,, therefore, also cause the inconvenience in the making moulding of this first shell 81 because this first shell 81 must have the design of several fixed legs 812; Moreover when directly this circuit board 85 being fixed in this fixed leg 812, this circuit board 85 hinders air-flows easily and gets into these hollow housings from this air inlet 811, and then is difficult for keeping a preferable heat-dissipating space between this circuit board 85 and this radiator fan 84; For example; When this circuit board 85 and these radiator fan 84 distances are too far away; 84 of this radiator fans can provide the radiating effect of this circuit board 85 quite limited; When this circuit board 85 and these radiator fan 84 distances were too near, this circuit board 85 influenced the water conservancy diversion effect of this radiator fan 84 on the contrary easily, causes the reduction in the service life of this light fixture 8 all easily again.
Again, please with reference to shown in Figure 2, for TaiWan, China is announced " high-capacity LED projecting lamp " novel patent case M269398 number.The existing light fixture 9 of this another kind has a printed circuit board (PCB) 91; On this printed circuit board (PCB) 91 led array 92 is set; And this printed circuit board (PCB) 91 is connected with a power supply circuit 911 backward; This printed circuit board (PCB) 91 led array 92 directions dorsad is provided with a fin 93, and with a radiator fan 94 enhance heat functions; In addition, several fixed legs 95 are set between this fin 93 and this power supply circuit 911, make between this fin 93 and this power supply circuit 911 to keep suitable heat-dissipating space.
Above-mentioned existing light fixture 9 mainly is to utilize the fixed leg 95 that is incorporated into this fin 93 to fix this power supply circuit 911; And utilize this fixed leg 95 to make between this power supply circuit 911 and this fin 93 can to keep suitable heat-dissipating space; Promoting the radiating effect of this light fixture 9, and can simplify the complicated integral structure degree relatively; Yet the radiator fan 94 of this existing light fixture 9 and the design of leaf frame free cause the water conservancy diversion effect of this radiator fan 94 quite limited; Moreover because this radiator fan 94 is side surfaces that are arranged at this fin 93, if when the height of the set electronic component in these power supply circuit 911 surfaces is higher, this electronic component possibly influence the rotation start of this radiator fan 94; The more important thing is; Because an end of this fixed leg 95 is directly to combine this fin 93; Even this fixed leg 95 capable of using is kept the distance between this power supply circuit 911 and this fin 93, but still can't guarantee whether can to keep between this power supply circuit 911 and this radiator fan 84 a preferable heat-dissipating space.
Summary of the invention
The present invention provides a kind of light fixture, makes to have preferable heat-dissipating distance between power supply circuit board and the radiator fan, is its main goal of the invention.
An of the present invention purpose provides a kind of difficult light fixture that influences radiator fan rotation start.
The light fixture according to the present invention is to comprise a radiator, a light-emitting component, a radiator fan, a power supply circuit board and a fixation kit.This light-emitting component is incorporated into this radiator; This radiator fan has a fan frame that is incorporated into this radiator, and this fan frame inboard is provided with an impeller; This this light-emitting component of power supply circuit board electrically connect; This fixation kit is incorporated between the fan frame and this power supply circuit board of this radiator fan, makes between this power supply circuit board and this radiator fan to have an airspace.
Beneficial effect of the present invention is: 1, reach this power supply circuit board of support by this fixation kit with effectively fixing, and make the preferable heat-dissipating distance of maintenance between this radiator fan and this power supply circuit board, guarantee that this power supply circuit board has the effect of predetermined heat dissipation effect.
2, the design that has " fan frame " by this radiator fan; The impeller of this radiator fan can be placed in this fan frame, and with the running of avoiding this impeller of shadow and the water conservancy diversion effect that can provide, and this fixation kit only utilizes this fan frame to fix especially; But not utilize this radiator to fix; Therefore, this fixation kit capable of using further guarantees to keep between this impeller and this power supply circuit board preferable heat-dissipating distance, to reach the effect that promotes the integral heat sink effect.
