技术领域 FIELD

[0001] 本实用新型是关于一种灯具及其散热器,特别是一种利用风扇驱使空气流通以辅助散热,且更适用于嵌入式场合,以提供室内或室外照明的灯具及其散热器。 [0001] The present invention relates to a lamp and a heat sink, in particular by a fan driven by an air flow to aid in cooling, more suitable for embedded applications, to provide indoor or outdoor lighting fixtures and radiator.

背景技术 Background technique

[0002] 现有灯具结构,如中国台湾公告M330426号《灯具散热结构》专利案,请配合参照图1所示,是依照该灯具的实际装设方向翻转180度,该灯具具有一散热座体81、一电路板82、一发光二极管83、一散热风扇84及一灯头85。 [0002] The conventional lamp structure, such as China Taiwan Publication No. M330426 "heat lamps structure" patent case, please refer to FIG. 1 with, is rotated 180 degrees in accordance with the actual mounting direction of the lamp, the lamp having a heat sink member 81, a circuit board 82, an LED 83, a cooling fan 84 and a cap 85. 该散热座体81具有一凹陷部811及一容置部812,该电路板82及发光二极管83设于该凹陷部811内,该散热风扇84则设于该容置部812内,且该灯头85结合于该容置部812外侧。 The cooling block 81 has a recess portion 811 and a receiving portion 812, the circuit board 82 and the light emitting diode 83 is provided inside the recess portion 811, the cooling fan 84 is provided inside the accommodating portion 812, and the base 85 812 combined with the outer receiving portion. 其中,该散热座体81另设有贯穿至该容置部812的数个散热孔813,该灯头85则设有数个导风孔851,因此,当该散热风扇84运转时,可驱使空气经由各该导风孔851被吸入该容置部812内,并由各该散热孔813排出, 以驱散该灯头85所产生的热能。 Wherein the cooling block 81 through to the other with the accommodating portion 812 of the plurality of cooling holes 813, the cap 85 is provided with a plurality of air guide holes 851, therefore, when the operation of the cooling fan 84, air can be driven via each of the air guide hole 851 is sucked into the accommodating portion 812, and is discharged from each of the cooling holes 813 to dissipate heat generated by the lamp 85.

[0003] 其使用时,将该灯头85结合于一灯座,并使各该散热孔813及导风孔851外露,以便该容置部812内的空气得与外界互相流通。 [0003] When using it, the cap 85 in conjunction with a socket, and each of the cooling holes 813 and the air guide hole 851 is exposed, so that the air in flow communication with the outside world to give 812 of the receiving portion. 然而,此现有结构用以吸入空气的各该导风孔851位于该灯具的较上方处,且基于热空气上升原理,各该散热孔813所排出的热空气会上升并积于该灯具较上方的周遭,并经由各该导风孔851再次被吸入,影响散热效能。 However, this conventional structure of each of the air guide hole 851 for the intake air is located at the top than the lamp, and based on the principle of rising hot air, hot air discharged from each heat dissipation hole 813 will rise and accumulate in the fixture than around the top, and through each of the air guide hole 851 is sucked again, affect the cooling performance. 而且,为了配合装潢的整体美观性需求,而必须将该灯具呈内嵌隐藏设置时,由于各该散热孔813及导风孔851埋入于装潢隔层的天花板上方,仅保留该发光二极管83部分显露于天花板表面,但天花板上方与建筑物本身的水泥楼层板之间的空间一般为封闭,该空间不易与外界空气循环,会影响其空气流通效果及散热效能,进而产生积热问题,影响该灯具的使用寿命ο Further, in order to meet the needs of the overall appearance of the decoration, the form must be embedded hidden when the lamp is provided, since each of the cooling holes 813 and the air guide hole 851 is buried in the barrier above the ceiling decoration, leaving only the LED 83 partially exposed to the ceiling surface, but above the space between the ceiling and the floor of the building itself cement board is generally closed space which is not easy with the outside air circulation will affect air flow effect and its thermal efficiency, and thus have a positive thermal problems, impact the lamp life ο

[0004] 另一种现有灯具结构,如中国台湾公告M346745号《端向排热式LED灯具》专利案, 再配合参照图2所示,该灯具具有一上壳91、一下壳92、一散热组件93及一LED灯组94,该上壳91内部具有一容置空间911,且该上壳91及下壳92可组装形成一灯具壳体,并使该散热组件93及LED灯组94设于该容置空间911内。 [0004] Another conventional lamp structure, such as China Taiwan Publication No. M346745 "LED lamp to the discharge end of the thermal" patent case, again with reference to Figure 2, the lamp 91 having an upper shell, a lower shell 92, a a heat dissipation assembly 93 and the LED group 94, the upper inner casing 91 has an accommodating space 911, and the upper case 91 and lower case 92 may be assembled to form a lamp housing, and the heat-dissipating assembly 93 and LED lamp set 94 disposed in the receiving space 911. 其中,该上壳91设有数个通气孔912,该下壳92则设有数个穿透孔921,因此,当该散热组件93的散热风扇931运转时,可驱使空气经由各该通气孔912被吸入该容置空间911内,并由各该穿透孔921排出,以驱散该LED灯组94所产生的热能。 Wherein, the upper shell 91 is provided with a plurality of vent holes 912, the lower housing 92 is provided with a plurality of through-holes 921, and therefore, when the cooling fan assembly 93193 operation, can be driven via the individual air vent hole 912 is the suction accommodating space 911, and the penetrating hole 921 is discharged by the thermal energy so as to disperse the LED lamp set 94 generated.

[0005] 然而,此现有结构用以吸入空气的各该通气孔912亦位于该灯具的上方处,使各该穿透孔921所排出的热空气也会上升,并经由各该通气孔912再次被吸入,影响散热效能。 [0005] However, this conventional structure for each of the intake air vent hole 912 also located at the top of the lamp, each of the hot air discharged from the penetration hole 921 will rise, and the vent hole 912 through each again inhaled, affect thermal performance. 且该现有结构呈内嵌隐藏设置时,虽然该各穿透孔921显露于天花板表面,但是各该通气孔912仍是埋入于天花板上方,故仍存在有空气流通及散热效能不佳,进而产生积热并影响该灯具使用寿命的问题。 When the conventional configuration and was embedded hidden settings, while each of the penetration hole 921 exposed to the ceiling surface, each of the vent holes 912 but is still embedded in the ceiling above, it is still there is poor air circulation and cooling efficiency, thereby generating heat build-up and the impact of the lamp life. 实用新型内容 SUMMARY
