Description
本創作涉及車燈的技術領域,尤其涉及一種利用光導管上設有一凹陷的微結構,達到投射出來的光形具有較大明暗對比度的車燈創新改良者。 The present invention relates to the technical field of a lamp, and particularly relates to an innovative improvement of a lamp having a concave structure on a light pipe to achieve a large light-dark contrast of the projected light shape.
近來,為了提高行車安全對於汽車車燈的照明光形設計,漸漸要求提高照明的對比度;一般用反射面的設計可以將光點聚到旁邊,因此可以克服,但利用導光管光導光的技術就會比較均勻,而不易達到光形左右不一樣亮的效果,較難符合法規要求,甚至是車燈廠內規。 Recently, in order to improve driving safety, the illumination light shape design of automobile lamps is gradually required to improve the contrast of illumination; generally, the design of the reflection surface can gather the light spots to the side, so that it can be overcome, but the light guiding technology using the light guide tube It will be more uniform, and it is not easy to achieve the effect that the light shape is not bright, and it is difficult to meet the regulatory requirements, even the internal rules of the lamp factory.
如中華民國公告第I338637號,而申請第97151169號之「車燈」新型專利,其結構如其摘要所述:該車燈係分別利用一發光元件作為初始光源、一導光元件來計算該初始光源之一發散角度及該發散角度之發光面積,及一透鏡元件來提升該發光元件之光萃取效率,用以產生具有預定光形且高光萃取效率之光源,再透過一投射元件來提升該光源之光形對比度,使該車燈得以投射出一高對比度的明暗截止線。此外,因該發光元件之一發光面可設計為具有一預設形狀,因此不需使用其他光學元件即可投射一截面為預設形狀之光束,進而有效地提升該車燈之光利用效率。 For example, the Republic of China Announcement No. I338637, and the new patent of "Lights" of No. 97151169, whose structure is as described in the abstract: the vehicle lamp uses a light-emitting element as an initial light source and a light guiding element to calculate the initial light source. a diverging angle and a light emitting area of the divergence angle, and a lens element for improving light extraction efficiency of the light emitting element for generating a light source having a predetermined light shape and high light extraction efficiency, and then lifting the light source through a projection element The light contrast allows the headlight to project a high contrast cut-off line. In addition, since one of the light-emitting surfaces of the light-emitting element can be designed to have a predetermined shape, a light beam having a predetermined shape can be projected without using other optical elements, thereby effectively improving the light utilization efficiency of the light.
然而,如第五圖所示為依前述I338637號「車 燈」的發光元件與導光元件繪示的光線路徑示意圖,即該引證案導光元件的入光面接至該發光元件之發光面,該導光元件接收該初始光源後,經過集光與規則性的導引後仍是平均的向外投射,雖然藉導光元件提昇了光的利用效率,但是並沒有因此使改變其光形與明暗對比度。 However, as shown in the fifth figure, according to the aforementioned I338637 "car A light path diagram of the light-emitting element and the light-guiding element of the lamp, that is, the light-incident surface of the light-guiding element of the reference is connected to the light-emitting surface of the light-emitting element, and after receiving the initial light source, the light-guiding element passes through the light collection and the rule The guiding of the sex is still an average outward projection. Although the light guiding element enhances the light utilization efficiency, it does not change its light shape and light and dark contrast.
如第六圖所示為習式導光元件導光路徑所投射出來照明光形a以及水平維度的光線強度分佈曲線b的示意圖,雖然,第六圖的照明光形a在視覺上尚難看出左右明暗有何差異,但由圖中之水平維度的光線強度分佈曲線b呈現緩和的曲線分佈,顯示其照明光形a的左右明暗對比差距較小,而無法符合較嚴格的法規要求。 As shown in the sixth figure, the illumination light shape a projected by the light guiding path of the light guiding element and the light intensity distribution curve b of the horizontal dimension are shown, although the illumination light shape a of the sixth figure is visually ugly. What is the difference between the left and right light and dark, but the light intensity distribution curve b of the horizontal dimension in the figure shows a gentle curve distribution, showing that the contrast between the left and right light and dark of the illumination light shape a is small, and cannot meet the stricter regulatory requirements.
雖然,車燈的設計上尚可配合一片特定形狀之遮光片,使該發光元件所發出的光線透過該遮光片的遮擋,而僅有部份的光線從該投射透鏡平行投射出一截面符合法規形狀之光束。但是這樣一來,因為該遮光片之因素,將會降低整體光利用效率,是為習式車燈結構的缺點之一。 Although the design of the lamp can be matched with a specific shape of the light shielding sheet, the light emitted by the light emitting element is blocked by the light shielding film, and only part of the light is projected from the projection lens in parallel to a section conforming to the regulations. The beam of shape. However, as a result of the visor, the overall light utilization efficiency will be lowered, which is one of the disadvantages of the conventional lamp structure.
再者,在車燈既有結構上所增設的遮光片又進一步造成結構與組裝上的複雜度,而且使重量增加,為其缺點之二。 Moreover, the additional light shielding sheet on the existing structure of the lamp further causes structural and assembly complexity, and the weight is increased, which is the second disadvantage.
所以,如何針對習式車燈結構使用遮光片結構造成光線能量損失而降低光利用效率,以及進一步造成結構的複雜與重量的增加,以及使用導管雖提高光利用率卻難以調製能量分布等缺點而進行創新改良,是為本案所欲行解決的困難點所在。 Therefore, how to use the visor structure for the conventional lamp structure to reduce the light energy loss and reduce the light utilization efficiency, and further increase the complexity and weight of the structure, and the use of the conduit to improve the light utilization efficiency, but it is difficult to modulate the energy distribution. Innovative improvement is the difficult point to solve in this case.
