Description of the invention: [Technical field of the invention] The present invention relates to an LED lamp, in particular to an LED lamp with adjustable illumination color, which has a headlight, a fog lamp, a direction lamp or a brake lamp. Special features. [Prior Art] At present, LEDs are widely used in lighting fixtures because of their advantages of high brightness, power saving, small size, etc. Recently, taillights, directional lights, brake lights, etc. in the lamps have been used as LEDs. the design of. Due to the large size of the tail light and the brake light, more LED point light sources are needed. For the common LED point light source, the reflective design is used, as shown in the seventh figure, which is a little light source (5 〇). Schematic diagram of the structure, which mainly comprises: ' ... reflector (5 1 )' whose inner layer is a reflective material for reflecting the LED light source (5 2 ), fixed to the reflector (5 丄) by the reflector (5 1 ) concentrating the light forwards; and the cover (5 3 ) is attached to the reflector (5 丄 mouth, which can produce a light shape according to the desired light of the lamp. Adjust the use of semi-convex lenses or plane lenses, etc. Brother, as described above, the design of the point source is to set the light-emitting surface of the led light forward, so that I 2 ) can be forwarded to the front cover (5 3 ) Part of the side light is then reflected by the reflection Κ 5 ,, and the direction is emitted 'that is, the hemispherical full I reflector 1292243 (5 1 ) is required. However, the use of a full-cover reflector can take up too much volume and needs to be improved. SUMMARY OF THE INVENTION To this end, the main object of the present invention is to provide a projection type lED lamp, which uses only a half-volume half-reflection cover, which greatly reduces the volume of the entire LED lamp and expands its application field. The main technical means used to achieve the above purpose is that the projection type led lamp is composed of a plurality of reflective LED point light sources, and each (10) point light source mainly sets the LED "source level" on a pedestal and makes it emit light. Faced, "and then placed on the susceptor base, an inner surface is formed with multiple continuous free curved two, half shot hood to refract the light emitted by the LED light source upwards: end opening:: shot. Such as A, the projected point The light source only needs half of the reflection, that is, the light of the full LED light source is emitted to the front end opening, so that the 'shooting type lamp has the advantage of miniaturization. The purpose of the lamp is to provide a car that can be easily changed into different functions. In the above-mentioned projection type point source, the half-reflection cover opening is provided with a design of the slanting edge of the slanting edge. When the projection point source is light, the illuminating point light source of the near-light fog lamp is changed. Present Embodiments Referring to the first and second sources, a preferred embodiment of a source (1 η, λα 斤 is a projection spot υ J, comprising: a first pedestal (X)丄); 1296243 * A second pedestal (i 2), disposed under the first base (丄丄), and the first base i) of the vehicle is long, so the front end is longer than the long end of the first base (1 1); The light source (丄3) is fastened on the first base (1 1 ) with the light emitting surface facing upward, and the LED money (13) mainly comprises a positioning seat (1 3 1 ) and an LED component (丄3) 2), the LED element (1 3 2 ) is fixed on the positioning seat (丄3 i ), and then fixed on the reflection cover (1 4 ) by the positioning seat (1 3 1 ); the LED element. (丄3 2) The system may include a monochromatic light-emitting diode or a light-mixing color-emitting diode; 1) a half-reflector (1 4 ) is formed in the upper portion, and is disposed on the first base The LED % source (1 3 ), the semi-reflective cover (i 4 has multiple continuous free-form surfaces, and a lamp cover (1 5 ) is fixed on the front side of the second base (丄2), corresponding to the ^ The base (ii) is combined with the semi-reflective cover (丄4) to form
的開口，並與開口間隔一適當距離；該燈罩（丄5 )係為 一非球面透鏡；及 μ _ 一遮片（1 6 )，係設置於該第一基座（i丄）前端， 其頂端高於該第一基座（1 1 )的上端面。 請配合參閱第三圖及第四圖所示，由於本發明係將匕肋 光源（1 3 )水平擺放於該第一基座（丄丄）上，令其發 光面朝上使光線向上發射，如此只要配合一半反射罩（1 4 )即能完全將LED光源（i 3 )的光線向前折射，令光 線經由燈罩（1 5 )折射後向外射出。是u，本發明相較 5 1296243 於反射式LED車燈，確實能有效縮減體積，為一小型化的 點光源。 又’由於第一基座（11)前端設有一遮片（16)， 故出光光線文該遮片（1 6 )形狀影響，而改變出光光形。 是以’該LED點光源（1 0 )即可被修正如同近燈或霧燈 的出光光形。即，若要產生近燈效果的出光光形，如第一 圖所不’該遮片（1 6 )的右上角落係形成一約15度的 斜切邊，若要產生霧燈出光光形，則該遮片（1 6，）的頂 端保持水平。此外，當本發明的投射式點光源（丄〇 )未 放置遮片時，該燈罩的出光會呈現一遠燈光形。 叫參閱第五圖所示，係為上述投射式點光源組合成一 大尺寸車燈（2 〇 )的立體外觀圖，即欲生產目前車輛使 、的各種車垃（2 〇 )，係將上述複數投射式點光源予以 群聚組合，即能構成一車燈產品。 欠由上述說明可知，本發明藉由LED光源設置方向的調 1即/、要使用半反射罩，即能有效地將全部光線予以折 向前端燈罩，由燈罩予以折射後對外發射。再配合不 5 /狀的遮片，調整出光光形，以方便生產近燈頭燈、遠 燈頭燈或霧燈。 【圖式簡單說明】 苐1 :係本發明投射4 LED點光源—較佳實例的前 視分解立體圖。 第二圖··係第一圖的組合外觀圖。 第二圖：係第二圖的部份側剖面圖。 6 1296243 第四圖··係本發明的一光線行進路線圖。 第五圖：係本發明LED車燈的立體外觀圖。 第六圖：係既有反射式LED點光源的側剖圖。 第七圖：係既有反射式頭燈的結構示意圖。 【主要元件符號說明 ] (1 0 )點光源 (1 1 )第一基座 (1 2 )第二基座 (1 3 ) LED 光源 (131)定位座 (1 3 2 ) LED 元件 (1 4 )半反射罩 (141)多重連續自由曲面 (1 5 )燈罩 (16) ( 1 6 ’）遮片 (5 0 )點光源 (5 1 )反射罩 (5 2 ) LED 光源 (6 0 )遮片 (5 3 )前罩 7The opening is spaced apart from the opening by an appropriate distance; the lamp cover (丄5) is an aspherical lens; and the μ_a mask (16) is disposed at the front end of the first base (i丄) The top end is higher than the upper end surface of the first base (1 1 ). Please refer to the third figure and the fourth figure. Since the present invention places the rib light source (13) horizontally on the first pedestal (丄丄), the light emitting surface faces upward to cause the light to be emitted upward. Therefore, the light of the LED light source (i 3 ) can be completely refracted forward by the half reflector (1 4 ), and the light is refracted through the lamp cover (15) and then emitted outward. It is u. Compared with the 5 1296243 reflective LED lamp, the invention can effectively reduce the volume and is a miniaturized point light source. Moreover, since the front end of the first pedestal (11) is provided with a mask (16), the light ray is affected by the shape of the mask (16), and the light shape is changed. Therefore, the LED point light source (10) can be corrected as the light pattern of the near lamp or the fog lamp. That is, if the light pattern of the near-light effect is to be generated, as shown in the first figure, the upper right corner of the mask (16) forms a beveled edge of about 15 degrees, and if the fog light is to be generated, Then the top of the mask (1, 6) remains horizontal. In addition, when the projection point light source (丄〇) of the present invention is not placed with a matte, the light output of the lampshade will exhibit a far-light shape. Referring to the fifth figure, it is a three-dimensional appearance of the above-mentioned projected point light source combined into a large-size headlight (2 〇), that is, the various vehicles (2 〇) to be produced by the current vehicle, the above plural Projected point sources are grouped together to form a headlight product. As can be seen from the above description, the present invention can be used to effectively align all the light to the front end lamp cover by adjusting the direction of the LED light source, that is, using a semi-reflective cover, which is refracted by the lamp cover and then emitted. In combination with the 5/shaped mask, the light shape is adjusted to facilitate the production of near-lamp headlights, far-lamp headlights or fog lamps.
