Description
Technical field
The present invention is about a kind of light fixture, especially a kind ofly guarantees that extraneous air-flow can circulate in its inner light fixture smoothly.
Background technology
Please refer to shown in Figure 1ly, existing light fixture 9 comprises a housing 91, a light-emitting component 92, a radiating module 93 and a circuit board 94.The periphery wall of this housing 91 is provided with an inlet section 911 and an outlet section 912; This light-emitting component 92, radiating module 93 and circuit board 94 are assembled in the inside of this housing 91, and wherein this light-emitting component 92 is in conjunction with this radiating module 93, and 94 of this circuit boards are electrically connected this light-emitting component 92.Whereby, when this light-emitting component 92 produces heat in actual use, then can utilize the effect of this radiating module 93, so that introduce extraneous air-flow by this inlet section 911, and further utilize this radiating module 93 to make this external world's air communication cross this outlet section 912 heat is passed to extraneous space, reaching predetermined radiating effect, and then can prolong the service life of this light fixture 9.
Yet, be provided with several electronic components 95 in addition on the circuit board 94 of existing light fixture 9, when this circuit board 94 is assembled in these housing 91 inside, respectively this electronic component 95 is between these housing 91 close ends and this circuit board 94 of inlet section 911, causing must keeping between this circuit board 94 and this housing 91 can be for the ccontaining space of this electronic component respectively 95, and because respectively this electronic component 95 all has an axial height (h), so cause the distance between this circuit board 94 and this housing 91 excessive, the actual assembled position that makes this circuit board 94 is roughly between the inlet section 911 and this radiating module 93 of this housing 91.Therefore, as shown in Figure 2, when these radiating module 93 desires are introduced in the process of extraneous air-flow by this inlet section 911, this circuit board 94 can form greatest obstruction to the current path of these housing 91 inside, cause extraneous air-flow can't circulate in this housing 91 inside smoothly, cause the radiating effect of this radiating module 93 to reduce, and then reduce the service life of this light-emitting component 92.
For solving the shortcoming of above-mentioned existing light fixture 9, also there is relevant dealer to develop and announces " the circuit board structure-improved of LED light fixture " novel patent case M339780 number as TaiWan, China.This novel patent case mainly is to form at least one air-vent on the circuit board of LED lamp interior, and this air-vent is positioned at the zone that this circuit board is not provided with electronic component and circuit, and this air-vent runs through two side surfaces of this circuit board.Whereby, when making this LED light fixture import extraneous air-flow, this external world's air-flow can utilize the design of this air-vent, and circulates in the inside of this LED light fixture smoothly, and then can guarantee that this LED light fixture has preferable radiating effect.
Though the circuit board structure-improved of this LED light fixture can circulate in the inside of this LED light fixture to guarantee extraneous air-flow swimmingly by the design of this air-vent; Yet, also, make the making step of this circuit board too loaded down with trivial details because this circuit board must additionally form this air-vent; In addition, this air-vent must be positioned at the zone that this circuit board is not provided with electronic component and circuit, so when desiring on this circuit board to form this air-vent, at the also suitable difficulty of the making step of this air-vent, therefore, cause the inconvenience on this circuit board making.Moreover even form this air-vent on this circuit board, this circuit board still can form obstruction to a certain degree to the current path of this LED lamp interior, causes the radiating effect of this LED light fixture not good.
