Description
Technical field
The invention relates to a kind of light fixture, especially a kind of light fixture that can constitute a hollow housing by radiator.
Background technology
Please refer to shown in Figure 1ly, existing light fixture 8 has a heat radiator body 81, and the outer peripheral face of this heat radiator body 81 is provided with several fins 811; Again, an end of heat radiator body 81 is in conjunction with a light-emitting component 82, and the other end arranges an electrical connector 83, and this electrical connector 83 electrically connects this light-emitting component 82; Whereby, can be by control this light-emitting component 82 projection light as Control Components such as circuit boards after these electrical connector 83 energisings; Whereby, when this light-emitting component 82 and this electrical connector 83 produce heat in operation, can utilize auxiliary heat radiation of conduction of heat of this heat radiator body 81.
Yet, though the heat that the heat radiator body 81 of existing light fixture 8 produced in the time of can absorbing this light- emitting component 82 and 83 runnings of this electrical connector.Just the volume of this heat radiator body 81 must enough provide the thermolysis that this light-emitting component 82 and this electrical connector 83 are scheduled to, and therefore, the overall volume of this heat radiator body 81 is slightly heavy, causes the inconvenience in the use; Moreover, because this light fixture 8 there is no the design that similar " air vent " reaches " radiator fan "; Therefore, cause this light-emitting component 82 and this electrical connector 83 can't reach good result of ventilating heat dissipation, influence the integral heat sink effect of this light fixture 8 easily, make reduce the service life of this light-emitting component 82.
For solving the shortcoming of aforementioned existing light fixture 8, as shown in Figure 2, disclose another kind of existing light fixture 9, this light fixture 9 comprises one first shell 91, one second shell 92, a circuit board 93, heat radiation module 94 and a light-emitting component 95.This first shell 91 is provided with several inlet air holes 911, and this second shell 92 is provided with several exhaust vents 921, and this circuit board 93, heat radiation module 94 and 95 of light-emitting components are arranged at this first shell 91 and second shell 92 is mutual in the hollow housing that constitutes after organizing; Wherein this heat radiation module 94 is made of a radiator fan 941 and a radiator 942, and this circuit board 93 electrically connects this radiator fan 941 and light-emitting component 95, and this light-emitting component 95 is in conjunction with this radiator 942.
When this light-emitting component 95 produces thermal source because of energising, then can utilize this circuit board 93 to drive this radiator fan 941 work, so that via this inlet air hole 911 respectively introducing extraneous air-flow, and the heat that cooperates these radiator 942 these light-emitting component 95 thermals source of conduction to produce, further utilize this radiator fan 941 to make this external world's air-flow via this exhaust vent 921 respectively heat is passed to extraneous space again, reaching predetermined radiating effect, and then can prolong the service life of this light-emitting component 95.
Above-mentioned existing light fixture 9 still has many shortcomings as described below when reality is used:
1, complex structure and assembling inconvenience: this light fixture 9 must utilize this first shell 91 and this second shell 92 hollow housing that group is formed, can ccontaining this circuit board 93, members such as heat radiation module 94 and light-emitting component 95; Therefore, overall structure is comparatively complicated, and causes comparatively inconvenience in the assembling; Moreover this first shell 91 and this second shell 92 must be processed to form this inlet air hole 911 and this exhaust vent 921 separately, and it is not good not only to make convenience, causes the raising of manufacturing cost yet.
2, radiating effect is not good: the extraneous air-flow that this radiator fan 941 is introduced from this inlet air hole 911, mainly in order to dispel the heat at this light-emitting component 95, design with this inlet air hole 911 and this exhaust vent 921, still quite limited to 93 radiating effects that can provide of this circuit board, therefore, the heat sinking function of existing light fixture 9 still has the space of improvement.
