Description
本發明係關於一種光投射結構,尤指一種用於照明裝置。 The present invention relates to a light projection structure, especially to a lighting device.
隨著汽車工業的發展,車用頭燈的亮度以及光分佈之區域也有一定的規範要求,如果燈光亮度分佈不均,或亮度分佈範圍太小,將會造成行車安全。 With the development of the automobile industry, the brightness of the headlights and the area of light distribution also have certain specification requirements. If the brightness distribution of the lights is uneven, or the brightness distribution range is too small, it will cause driving safety.
隨著汽車科技的不斷發展,車輛的大燈也隨之發展,從鹵素車燈、氙氣車燈等和LED車燈都相繼出現在不同車型上,鹵素車燈就是特殊的白熾燈,其被廣泛用於汽車照明領域,原理是利用電阻有電流通過會發熱,當溫度足夠高時發出波長在可見光頻段的黑體輻射,其一般分為碘鎢燈和溴鎢燈,不同白熾燈點亮後,雖說其燈絲溫度並不及鎢的沸點,但是仍然會有少量的鎢在高溫下揮發,當揮發的鎢遇冷後就會凝結,不久就會在燈泡內壁形成發黑的鎢膜。 With the continuous development of automotive technology, the headlights of vehicles have also developed. From halogen headlights, xenon headlights, and LED headlights have appeared on different models one after another. Halogen headlights are special incandescent lamps, which are widely used. It is used in the field of automotive lighting. The principle is to use a resistor to generate heat when current passes through it. When the temperature is high enough, it emits black body radiation with a wavelength in the visible light band. It is generally divided into iodine-tungsten lamps and bromine-tungsten lamps. The temperature of the filament is not as high as the boiling point of tungsten, but there will still be a small amount of tungsten volatilized at high temperature. When the volatilized tungsten is cooled, it will condense, and soon a black tungsten film will be formed on the inner wall of the bulb.
氙氣車燈(High Intensity Discharge Lamp),其係一種氣體放電燈,該氙氣車燈是利用配套的電子鎮流器將蓄電池的12V電壓瞬間提升到23kV以上的觸發電壓後,高壓脈衝電在完全密閉的微型石英燈泡內的金屬電極之間,激勵燈泡內的物質(氙氣、少量的水銀蒸氣以及金屬鹵化物)在電弧中電離產生光亮,氙氣汽車大燈有兩個顯著的優點:一方面是氙氣燈泡擁有比普通鹵素燈泡高三 倍的光照強度,耗能卻僅為其三分之二;而另一方面是氙氣燈泡採用與日光相近的光色,為駕駛者創造出更佳的視覺條件。 High Intensity Discharge Lamp (High Intensity Discharge Lamp), which is a gas discharge lamp, the xenon lamp is a high-voltage pulse electricity after the battery's 12V voltage is instantly raised to a trigger voltage of 23kV or more by using a matching electronic ballast. Between the metal electrodes in the miniature quartz bulb, the substances in the excitation bulb (xenon gas, a small amount of mercury vapor and metal halide) are ionized in the arc to produce light. Xenon headlights have two significant advantages: on the one hand, xenon gas The bulb has three higher than ordinary halogen bulbs On the other hand, xenon bulbs use a light color similar to that of sunlight, creating better visual conditions for drivers.
LED車燈(Light Emitting Diode),又稱為發光二極體,現今許多車輛尾燈、高位剎車燈以及日間行車燈的重要組成部分,甚至還有車輛將其應用在車輛大燈上,LED的發光效率更高,能耗僅為鹵素燈的1/20,而其使用壽命長達10萬小時,整車設計壽命里基本不用更換。另外其體積小巧,緊湊便於布置和造型設計。 LED lights (Light Emitting Diode), also known as light-emitting diodes, are an important part of many vehicle tail lights, high-mounted brake lights and daytime running lights, and even vehicles use them in vehicle headlights. The luminous efficiency is higher, the energy consumption is only 1/20 of the halogen lamp, and its service life is as long as 100,000 hours, and there is basically no need to replace it in the design life of the whole vehicle. In addition, its small size, compact and easy to arrange and shape design.
在先前技術中,車用頭燈大多都是產生固定的光場與亮度,車燈所發出之光線大多集中於前方的區域,對於周圍之亮度則較為薄弱,車子周圍對駕駛人來說將出現更多死角,當夜間行車或行駛至燈光昏暗的地方時,若周圍有狀況發生,如行人或動物朝車體前方區域移動,以及行車轉彎時,由於車體前方週圍亮度不足,當行人、動物或物體已出現於車體前方,且車速較快,駕駛人往往反應不及,進而導致意外發生。 In the prior art, most car headlights generate a fixed light field and brightness. Most of the light emitted by the headlights is concentrated in the front area, and the brightness of the surrounding area is relatively weak, and the surrounding area of the car will appear to the driver. There are more blind spots. When driving at night or driving to a dimly lit place, if there are conditions around, such as pedestrians or animals moving towards the area in front of the vehicle body, and when driving turns, due to insufficient brightness in front of the vehicle body, when pedestrians, animals, Or the object has appeared in front of the car body, and the speed of the car is fast, the driver is often unable to react in time, which leads to an accident.
