技术领域technical field

本发明是关于一种灯具，尤其是一种可借助散热器构成一中空壳体的灯具。The invention relates to a lamp, especially a lamp which can form a hollow shell by means of a radiator.

背景技术Background technique

请参照图1所示，现有灯具8具有一散热本体81，该散热本体81的外周面设有数个鳍片811；又，散热本体81的一端结合一发光元件82，另一端设置一电连接件83，该电连接件83电性连接该发光元件82；借此，该电连接件83通电后可通过如电路板等控制组件控制该发光元件82投射灯光；借此，当该发光元件82及该电连接件83于运作过程中产生热量时，即可利用该散热本体81的热传导作用辅助进行散热。Please refer to Fig. 1, the existing lamp 8 has aheat dissipation body 81, and the outer peripheral surface of theheat dissipation body 81 is provided withseveral fins 811; 83, theelectrical connector 83 is electrically connected to the light-emittingelement 82; thereby, after theelectrical connector 83 is energized, the light-emitting element 82 can be controlled to project light through control components such as a circuit board; thereby, when the light-emittingelement 82 And when theelectrical connector 83 generates heat during operation, it can use the heat conduction function of theheat dissipation body 81 to assist in heat dissipation.

然而，现有灯具8的散热本体81虽然可吸收该发光元件82及该电连接件83运作时所产生的热量。只是该散热本体81的体积必须足够提供该发光元件82及该电连接件83预定的散热作用，因此，该散热本体81的整体体积略为笨重，造成使用上的诸多不便；再者，由于该灯具8并无类似“通风孔”及“散热风扇”的设计；因此，导致该发光元件82及该电连接件83无法达到良好的通风散热效果，容易影响该灯具8的整体散热效果，令该发光元件82的使用寿命降低。However, although theheat dissipation body 81 of the conventional lamp 8 can absorb the heat generated when thelight emitting element 82 and theelectrical connector 83 are in operation. Only the volume of theheat dissipation body 81 must be sufficient to provide the predetermined heat dissipation effect of thelight emitting element 82 and theelectrical connector 83. Therefore, the overall volume of theheat dissipation body 81 is slightly heavy, causing many inconveniences in use; 8 has no design similar to "ventilation holes" and "cooling fans"; therefore, the light-emittingelement 82 and theelectrical connector 83 cannot achieve good ventilation and heat dissipation effects, which easily affects the overall heat dissipation effect of the lamp 8, making the luminous The service life of theelement 82 is reduced.

为解决前述现有灯具8的缺点，如图2所示，揭示另一种现有灯具9，该灯具9包含一第一外壳91、一第二外壳92、一电路板93、一散热模组94及一发光元件95。该第一外壳91设有数个入风孔911，该第二外壳92设有数个出风孔921，该电路板93、散热模组94及发光元件95则设置于该第一外壳91及第二外壳92相互对组后所构成的中空壳体内；其中该散热模组94由一散热风扇941及一散热器942所构成，该电路板93电性连接该散热风扇941及发光元件95，该发光元件95结合该散热器942。In order to solve the shortcomings of the aforementioned existing lamp 8, as shown in Figure 2, another existinglamp 9 is disclosed, which includes afirst shell 91, asecond shell 92, acircuit board 93, aheat dissipation module 94 and alight emitting element 95. Thefirst casing 91 is provided with severalair inlet holes 911, and thesecond casing 92 is provided with severalair outlet holes 921. Theshells 92 are paired with each other to form a hollow housing; wherein theheat dissipation module 94 is composed of aheat dissipation fan 941 and aheat sink 942, and thecircuit board 93 is electrically connected to theheat dissipation fan 941 and thelight emitting element 95. Thelight emitting element 95 is combined with theheat sink 942 .

当该发光元件95因通电产生热源时，则可利用该电路板93驱动该散热风扇941工作，以便经由各该入风孔911引入外界气流，并配合该散热器942传导该发光元件95热源所产生的热量，再进一步利用该散热风扇941使该外界气流经由各该出风孔921将热量传递至外界空间，以达到预定的散热效果，进而可延长该发光元件95的使用寿命。When the light-emitting element 95 generates a heat source due to electrification, thecircuit board 93 can be used to drive thecooling fan 941 to work, so that the outside air is introduced through theair inlet holes 911, and theradiator 942 is used to conduct the heat generated by the light-emittingelement 95. The generated heat is further utilized by thecooling fan 941 to transfer the external airflow to the external space through theoutlet holes 921 to achieve a predetermined heat dissipation effect, thereby prolonging the service life of thelight emitting element 95 .

上述现有灯具9于实际使用时，仍有如下所述的诸多缺点：When the above-mentioned existinglamp 9 is used in practice, there are still many disadvantages as follows:

1、结构复杂及组装不便：该灯具9必须利用该第一外壳91及该第二外壳92所对组而成的中空壳体，方可容置该电路板93、散热模组94及发光元件95等构件；因此，整体结构相对较为复杂，并导致组装上较为不便；再者，该第一外壳91及该第二外壳92必须另行加工形成该入风孔911及该出风孔921，不仅制作便利性不佳，也造成制造成本的提高。1. Complex structure and inconvenient assembly: thelamp 9 must use the hollow shell formed by the pair of thefirst shell 91 and thesecond shell 92 to accommodate thecircuit board 93, theheat dissipation module 94 and the luminous Components such ascomponents 95; therefore, the overall structure is relatively complicated, and it is inconvenient to assemble; moreover, thefirst shell 91 and thesecond shell 92 must be processed separately to form theair inlet hole 911 and theair outlet hole 921, Not only the manufacturing convenience is not good, but also the manufacturing cost is increased.

2、散热效果不佳：该散热风扇941自该入风孔911所引入的外界气流，主要用以针对该发光元件95进行散热，以该入风孔911及该出风孔921的设计而言，对该电路板93所能提供的散热效果仍相当有限，因此，现有灯具9的散热功能仍有改善的空间。2. The heat dissipation effect is not good: the external airflow introduced by theheat dissipation fan 941 from theair inlet hole 911 is mainly used to dissipate heat for thelight emitting element 95, in terms of the design of theair inlet hole 911 and theair outlet hole 921 , the heat dissipation effect that thecircuit board 93 can provide is still quite limited, therefore, there is still room for improvement in the heat dissipation function of the existinglamp 9 .
