Description

汽、機車之頭燈或霧燈
本發明係關於汽、機車之頭燈或霧燈，尤指一種利用LED燈與散熱元件間呈現一定角度之設置，得以讓汽、機車之頭燈或霧燈內所設LED燈之光源直接照射於光學反射面，並經前述光學反射面反射再經由透光之前燈罩投射出去，即可讓LED燈所產生之光源利用率達到最高程度，提升LED燈之照明效果。
按目前LED之車燈結構，如台灣發明專利申請第096138244號「LED燈具」主要係於燈殼內設有非對稱之第一、第二反射部，前述第一、第二反射部係分別設有一特定曲率之反射面；該照明裝置設置於容置空間內，該照明裝置包含可分別獨立照明之第一LED光源與第二LED光源，其中該第一、第二LED光源係分別朝向第一、第二反射部之反射面，藉以使該第一、第二LED燈分別投射之光線，可透過其對應之反射面而反射，以形成兩不同光束角度之光照範圍。然該習知者之LED燈係被設置於散熱裝置之兩側，且與散熱裝置形成同向設置，使得該LED燈所生之光源無法配合前述第一反射面與第二反射面之反射角度，以產生最高效率之光線反射效果，畢竟LED燈所產生之照度，係由LED燈之正中央向兩側逐漸衰減，但是當LED燈所產生之最強照度之光線與前述第一反射面與第二反射面無法產生最大接觸時，將會降低前述第一反射面與第二反射面之光線反射量，無法發揮LED燈應有之照度高效率。
次，如台灣新型專利申請第098215839號「車燈結構」，係於反射燈座內設有縱、橫向光學曲面，並以一燈罩設置於反射燈座上方，並設基板，以設置於前述反射燈座底部之鏤空孔處，於基板設置單一高功率LED燈，及以一導熱矽膠墊設置於前述基板，再以一導熱塊設置於前述導熱矽膠墊下方，可將高功率LED燈所產生的熱源傳導散熱。該習知者之缺點為：反射燈座內之光學曲面所接收到之LED燈光源，為位於照度最弱之兩側，致使該習知者僅能將LED燈所生之光源作最低效率之利用，造成該車燈無法發出高功率之照度。
為此，本發明者，基於多年車燈結構之設計與研究經驗，特針對目前市售之各種LED車燈之結構缺點，加以研究，發明本案。
本發明之目的，乃在提供一種能以提高LED燈之照度效率，以將LED燈更為普遍運用汽、機車之頭燈或霧燈，並降低LED燈之耗電量(本發明之耗電量約9瓦，傳統者約55瓦)，達到省電又環保之氣機車頭燈或霧燈之結構創新。
本發明之汽、機車之頭燈或霧燈，主要係於殼體內設光學反射面，前述光學反射面並與燈殼為一體，且燈殼可由鋁合金或鎂合金製成，讓燈殼具備反射與散熱之作用，降低車燈之溫度。
本發明之汽、機車之頭燈或霧燈，係於殼體內設散熱元件，前述散熱元件並與殼體互相組合，讓散熱元件配合車燈之散熱效率自由調整散熱面積。
本發明之汽、機車之頭燈或霧燈，其中散熱元件設LED燈槽，以為LED燈設置，且讓LED燈形成一∮角度之設置，讓LED燈所生之最強照度光源得以最佳度照射於光學反射面，提升LED燈之照度效率。
如此，為使　貴審查員可充份了解本發明，茲依附圖式解說如下：如圖1-3所示，本發明之汽、機車之頭燈或霧燈，至少包含：殼體1，係由鋁合金或鎂合金製成，如由鎂合金製成則具備有質輕，散熱效率更高之優點，但也並不限於前述兩種材質，如果有更好成本更低之新材質當然亦適用本發明之燈殼，前述燈殼1之內側並設光學反射面10，前述光學反射面10並設有不同光學反射曲線，以最高效率接收來自LED燈之所生之光源。且為使得本發明之汽、機車之頭燈或霧燈得以產生最佳之照明角度，並減少光源之損耗，乃於前述光學反射面10之上下方各設有直向紋路11，讓車燈投射出之光線呈現水平線狀，讓車燈之光源得以大部份水平分布於車前側之路面上方，符合歐規(ECE)或美規(SAE)或其他地區國家車輛燈具規範，車輛駕駛者得以藉由車燈得知路面資訊，且因為車燈光源分布於路面上，不會投射到對向來車之駕駛者眼睛，得以避免對向來車駕駛者之暈眩感，更能提高道路駕駛之安全。
前述殼體1內側並設結合槽12(如圖2及4)，前述結合槽12之底壁並設孔(圖中未示)以為栓設元件120穿過而與散熱元件2栓設為一體，並設有導線孔121，以為LED燈3之導線穿過，而與LED燈3連接。
前述殼體1後側設有基板槽13，得為LED燈3之控制電路基板5設置，並以栓設元件130殼體1栓固，再以蓋板14蓋合，前述蓋板14並以栓設元件140與前述殼體1之基板槽13結合，即可將前述控制電路基板5穩固設置於前述基板槽13中(如圖2及4)。
前述殼體1後側並與固定座4結合，於殼體1設有栓設孔15，得以栓設元件150穿過固定座4之孔40後與前述栓設孔15栓設，即可將殼體1與固定座4結合，並利用固定座4固定於車輛之燈槽內。
前述殼體1前側並設有透光性之前燈罩6，以將LED燈形成保護作用並讓車燈之光源得以穿透而照設於路面上。
如圖1、5-7，前述散熱元件2係與殼體1之結合槽12結合，且於結合前並可於前述結合槽12之底壁內側塗佈散熱材料，如散熱膏等，以將散熱元件2所生之高溫迅速傳導到殼體1，增強散熱效果，前述散熱元件2並設有栓設孔20以為前述殼體1之栓設元件120栓設，即可將散熱元件2與殼體1之結合槽12結合為一體(如圖4)，前述散熱元件2設有LED燈槽21，前述LED燈槽21並設有斜向壁面210，且於前述散熱元件2並設有定位孔23，以為栓設元件24栓設後，將LED燈夾固於LED燈槽中。
前述LED燈3被設置於基板30上，且LED燈3共有二組，分別被設置於前述散熱元件2之兩側之LED燈槽21中，形成∮角度之結合，LED燈3如由第一LED燈3A與第二LED燈3B組成時，第一LED燈3A與第二LED燈3B並被分別設置於散熱元件2兩側之LED燈槽21中，且令第一LED燈3A與第二LED燈3B散熱元件2之兩側LED燈槽21之間形成有∮1與∮2角度，其中∮1得大於或等於或小於∮2，端視前述光學反射面10之設置方法而定，至於∮1與∮2角度得小於90度，以配合前述光學反射面10之設置，其目的乃是要讓前述LED燈3所生之最強照度正中央之光源得以直接照射於前述光學反射面10，讓LED燈3所產生之光源達到最高利用率，提升LED燈之照明效果，並因此得以降低耗電量，大大去除傳統高消耗功率之LED車燈之缺點。
綜上，本發明將LED燈之設置方向徹底顛覆傳統，讓LED燈所生之照度光源得以與殼體之光學反射面產生最佳之搭配角度，讓LED燈所生之照度光源得被殼體之光學反射面以最大效率反射出去，提升以LED燈製成之汽機車之頭燈或霧燈甚至其他用途之LED燈具，亦可因此而提高照明效率，降低消耗電力，更符合環保之要求，為本案之組成。
