Description
Technical field
The present invention is related to a kind of light fixture, and especially a kind of heat radiation module that can constitute by radiator and radiator fan, in order to the light fixture carrying out dispelling the heat for power supply circuit board.
Background technology
Refer to shown in Fig. 1, existing light fixture 8 substantially comprises one first shell 81, second housing 82, radiator 83, radiator fan 84, circuit board 85 and a light-emitting component 86. This first shell 81 can mutually to group with this second housing 82, and to constitute a hollow housing, wherein this first shell 81 is provided with several air inlet 811, and this second housing 82 is provided with several air outlet 821; Again, this radiator 83, radiator fan 84, circuit board 85 and light-emitting component 86 are fixed on inside this hollow housing, wherein this radiator fan 84 is in conjunction with this radiator 83, and this light-emitting component 86 amplexiforms in the side of this radiator 83, and this circuit board 85 is then electrically connected this light-emitting component 86.
This existing light fixture 8 is when actually used, it is connected to the lamp socket in place as first-class in wall, ceiling or table, it is electrically connected will pass through this lamp socket and general electric power system, and then utilize this circuit board 85 to make the energising of this light-emitting component 86 produce light, and via this second housing 82 by light projection to the external world. It addition, when this light-emitting component 86 produces thermal source because of energising, then by the conduction of heat of this radiator 83, and coordinate the water conservancy diversion start of this radiator fan 84, to provide this light-emitting component 86 predetermined radiating effect, therefore the service life of this existing light fixture 8 can be extended.
The above-mentioned another inner side perisporium in this first shell 81 of existing light fixture 8 forms several fixing post 812, and utilizes several screw 87 that this circuit board 85 is locked in respectively this fixing post 812, so can really be fixed on inside this first shell 81 by this circuit board 85; But, owing to this first shell 81 must have the design of several fixing post 812, therefore, also result in the inconvenience made in molding of this first shell 81; Furthermore, when directly this circuit board 85 being fixed on this fixing post 812, this circuit board 85 tends to interfere with air-flow and enters this hollow housing from this air inlet 811, and then not easily maintains a preferably heat-dissipating space between this circuit board 85 and this radiator fan 84; For example, when this circuit board 85 and this radiator fan 84 are from time too far away, the radiating effect that this radiator fan 84 can be provided by this circuit board 85 is fairly limited, again when this circuit board 85 and this radiator fan 84 are when too near, this circuit board 85 easily affects the water conservancy diversion effect of this radiator fan 84 on the contrary, all easily causes the reduction in the service life of this light fixture 8.
Again, refer to shown in Fig. 2, announce No. M269398 " high-power LED spotlight " new patent case for TaiWan, China. This another kind of existing light fixture 9 has a printed circuit board (PCB) 91, this printed circuit board (PCB) 91 arranges LED array 92, and this printed circuit board (PCB) 91 is connected to a power supply circuit 911 backward, this printed circuit board (PCB) 91 LED array 92 direction dorsad arranges a fin 93, and strengthens heat sinking function with a radiator fan 94; It addition, arrange several fixing post 95 between this fin 93 and this power supply circuit 911, make can keep between this fin 93 and this power supply circuit 911 suitable heat-dissipating space.
Above-mentioned existing light fixture 9 is fixed this power supply circuit 911 mainly by the fixing post 95 being incorporated into this fin 93, and utilize this fixing post 95 to make can keep between this power supply circuit 911 and this fin 93 suitable heat-dissipating space, to promote the radiating effect of this light fixture 9, and relatively can simplify complicated integral structure degree; But, the design of the radiator fan 94 also leaf frame free of this existing light fixture 9, the water conservancy diversion effect causing this radiator fan 94 is fairly limited; Furthermore, owing to this radiator fan 94 is disposed on a side surface of this fin 93, if the height of this electronic component set by power supply circuit 911 surface is higher, this electronic component will be likely to affect the rotation start of this radiator fan 94; The more important thing is, owing to one end of this fixing post 95 is directly in conjunction with this fin 93, even if this fixing post 95 available maintains the distance between this power supply circuit 911 and this fin 93, but still cannot guarantee whether can to maintain between this power supply circuit 911 and this radiator fan 84 a preferably heat-dissipating space.
Summary of the invention
The present invention provides a kind of light fixture, makes have preferably heat-dissipating distance between power supply circuit board and radiator fan, for the goal of the invention that it is main.
A time purpose of the present invention, is to provide a kind of radiator fan that not easily affects and rotates the light fixture of start.
According to light fixture of the present invention, it is 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 the fan frame being incorporated into this radiator, is provided with an impeller inside this fan frame; This this light-emitting component of power supply circuit board electrical connection; This fixation kit is incorporated between the fan frame of this radiator fan and this power supply circuit board, makes to have between this power supply circuit board and this radiator fan an airspace.
The present invention has the beneficial effects that: 1, by this fixation kit effectively to fix and to support this power supply circuit board, and make to keep preferably heat-dissipating distance between this radiator fan and this power supply circuit board, it is ensured that this power supply circuit board has effect of predetermined heat dissipation effect.
