Description
本發明涉及一種照明裝置，特別涉及一種發光二極體燈具。 The invention relates to a lighting device, in particular to a light emitting diode lamp.
發光二極體光源作為一種新興之第三代光源，雖然現在還不能大規模取代傳統之白熾燈，但是其具有工作壽命長、節能、環保等優點，而普遍被市場看好。而且，目前由發光二極體組成之模組能產生大功率、高亮度之光源，因此將廣泛地、革命性地取代傳統之白熾燈等習知之光源，進而成為符合節能環保主題之主要光源。 As a new generation of light source, the light-emitting diode light source can not replace the traditional incandescent lamp on a large scale, but it has the advantages of long working life, energy saving and environmental protection, and is generally favored by the market. Moreover, the current module consisting of a light-emitting diode can generate a high-power, high-brightness light source, and thus will widely and revolutionarily replace a conventional light source such as a conventional incandescent lamp, thereby becoming a main light source that meets the theme of energy conservation and environmental protection.
傳統之發光二極體燈具通常暴露在空氣中使用，這就要求該發光二極體不受外界環境如雨水等之影響，為了使發光二極體免受外界環境之影響，通常將發光二極體或其模組密封在封閉之空間內。同時，隨著發光二極體或其模組之功率、亮度之增大，其產生之熱量也越來越大，若不能妥善解決發光二極體之發熱問題，則發光二極體燈具之工作壽命將受到嚴重影響。因此，業界通常在發光二極體模組上安裝一散熱器對其進行散熱。 Conventional light-emitting diode lamps are usually exposed to the air, which requires the light-emitting diode to be protected from external environment such as rain, etc. In order to protect the light-emitting diode from the external environment, the light-emitting diode is usually The body or its module is sealed in a closed space. At the same time, as the power and brightness of the LED or its module increase, the heat generated is also increased.

The bottom end of the lamp cover 30 is received in the receiving groove 54 of the lower lamp cover 50, and the sealing ring 110 is sandwiched between the bottom end of the lamp cover 30 and the receiving groove 54. The plurality of screws 48 are sequentially inserted through the through holes 420 of the upper lamp cover 40 and the through holes 92 of the heat conducting sheet 90 to be engaged with the threaded blind holes 146 of the top end of the heat sink 10, thereby The heat conducting sheet 90 is sandwiched between the plate body 42 of the upper lamp cover 40 and the top end of the heat sink 10, and is simultaneously in close contact with the plate body 42 of the upper lamp cover 40 and the top end of the heat sink 10. with The upper lamp cover 40 is overlapped on the folded edge 34 of the lamp cover 30 and the sealing ring 100 is sandwiched between the upper lamp cover 40 and the folded edge 34 of the lamp cover 30 to function as a seal. At this time, the heat sink 10 and the light emitting diode 20 are housed in a sealed space formed by the upper lamp cover 40, the lamp cover 30, and the lower lamp cover 50. At this time, the LED of the present invention is assembled.
與習知技術相比，所述發光二極體燈具之螺釘48與緊固件120將該上燈蓋40、下燈蓋50和燈罩30組成一空間以收容散熱器10及發光二極體模組20，密封圈100壓在上燈蓋40與燈罩30之折邊34之間；密封圈110通過燈罩30底端壓在下燈蓋50之收容槽54內，從而將上燈蓋40、下燈蓋50和燈罩30組成之空間變成密封之空間，以防止雨水、灰塵等影響發光二極體模組20工作性能或者壽命。所述發光二極體燈具在散熱器10頂端與上燈蓋40之板體42之間夾置一由導熱性能良好之材料製成之導熱片90，該導熱片90同時與上燈蓋40之板體42和該散熱器10之頂端緊緊貼合，使得由發光二極體模組20產生之熱從散熱器10很快地傳遞到上燈蓋40之板體42上，進而散發到周圍之空氣中。由於所述緊固件120之螺紋桿體122在殼體126內沿著該殼體126之中心軸線移動，在該上燈蓋40之板體42未與導熱片90和散熱器10之頂端緊密貼合之情況下，或者在該上燈蓋40之板體42未壓緊密封圈100之情況下，再或者該上燈蓋40之板體42即未與導熱片90和散熱器10之頂端緊密貼合又未壓緊密封圈100之情況下，旋擰鎖合上燈蓋40之螺釘48，使得緊固件120之螺紋桿體122相對於殼體126向上移動，並使上燈蓋40之板體42即與導 熱片90和散熱器10之頂端緊密貼合又壓緊密封圈100，這樣螺釘48與緊固件120之配合使得本發明發光二極體燈具即具有良好之散熱效果又具有良好之密封性。 Compared with the prior art, the screw 48 and the fastener 120 of the LED lamp form a space for the upper lamp cover 40, the lower lamp cover 50 and the lamp cover 30 to receive the heat sink 10 and the light emitting diode module. 20, the sealing ring 100 is pressed between the upper lamp cover 40 and the folded edge 34 of the lamp cover 30; the sealing ring 110 is pressed into the receiving groove 54 of the lower lamp cover 50 through the bottom end of the lamp cover 30, thereby the upper lamp cover 40 and the lower lamp cover The space formed by the 50 and the lampshade 30 becomes a sealed space to prevent rain, dust, and the like from affecting the performance or life of the LED module 20. The light-emitting diode lamp has a heat-conducting sheet 90 made of a material having good thermal conductivity between the top end of the heat sink 10 and the plate body 42 of the upper lamp cover 40. The heat-conducting sheet 90 is simultaneously combined with the upper lamp cover 40. The plate body 42 and the top end of the heat sink 10 are tightly attached, so that the heat generated by the LED module 20 is quickly transmitted from the heat sink 10 to the board 42 of the upper lamp cover 40, and then radiated to the surroundings. In the air. Since the threaded rod 122 of the fastener 120 moves along the central axis of the housing 126 within the housing 126, the plate 42 of the upper lamp cover 40 is not closely attached to the top ends of the heat conductive sheet 90 and the heat sink 10. In the case where the plate 42 of the upper lamp cover 40 is not pressed against the sealing ring 100, or the plate 42 of the upper lamp cover 40 is not close to the top ends of the heat conducting sheet 90 and the heat sink 10. In the case of fitting and not pressing the sealing ring 100, the screw 48 of the lamp cover 40 is screwed, so that the threaded rod body 122 of the fastener 120 moves upward relative to the housing 126, and the plate of the upper lamp cover 40 is Body 42 is the guide The heat sheet 90 and the top end of the heat sink 10 are closely fitted and pressed against the sealing ring 100, so that the screw 48 and the fastener 120 cooperate to make the light-emitting diode lamp of the invention have good heat dissipation effect and good sealing property.
