車用智能燈光裝置(二) Intelligent lighting device for vehicles (2)

本發明係一種車用智能燈光裝置(二),詳而言之係關於一種能因應照明區域的環境亮度而調整照明強度,除具節省電力功能的設計外,更具有精確調整照明亮度之功效。 The invention relates to a vehicle intelligent lighting device (2). In detail, it relates to a lighting intensity that can be adjusted according to the ambient brightness of the lighting area. In addition to the design of saving power, the invention has the effect of accurately adjusting the brightness of the lighting.

按,自行車運動已經成為現在社會大眾最熱門的健身方式,騎乘自行車除了能達到健身功效外,也可避免二氧化碳的排放而危害到空氣,又自行車不論男女老少皆可操作使用,所以,許多人都利用空餘時間到較空曠之場所騎乘。 According to the bicycle movement, it has become the most popular fitness method for the public. In addition to the fitness effect, riding bicycles can also avoid carbon dioxide emissions and endanger the air. Bicycles can be operated regardless of gender, so many people They all use spare time to ride in a more empty place.

然而,在這些熱愛騎乘自行車的人們裡,有些人因工作因素,以致於騎乘的時間必須延至天色較暗的晚上才可騎乘,又人們的眼睛視力在晚上時,容易因天色因素而造成視覺感官下降,且一般騎乘者並非在封閉的場所內騎乘,而有容易與其他之汽、機車及路人共同使用同一道路之情形發生,所以,在晚上騎乘自行車更容易發生交通意外,為此,為了提供周圍的汽、機車或路人清楚明辨前方有騎乘自行車人員的存在,騎乘者會在自行車上或在身上穿戴上具反光或可發亮的裝置,以避免交通意外的發生。 However, in those who love to ride bicycles, some people have to rely on work factors, so that the riding time must be extended to the darker nights to ride, and people's eyesight at night is easy due to the sky factor. The visual sense is reduced, and the general rider does not ride in a closed place, but it is easy to use the same road with other steam, locomotives and passers-by. Therefore, riding a bicycle at night is more likely to cause traffic accidents. To this end, in order to provide the surrounding steam, locomotive or passerby to clearly identify the presence of a bicycle rider in front, the rider will wear a reflective or shiny device on the bicycle or on the body to avoid traffic accidents. happened.

習用的自行車燈請參閱中華民國專利公告號第 356790號之「自行車閃光警示器結構改良」,其係一種自行車閃光警示器結構改良,尤指一種於行車及光線不足時自動啟動產生閃光,停車或光線充足時自動關閉之結構者。主要乃具有一LED閃光驅動電路,於其輸出端乃分別連接有LED(發光二極體),該LED之負極端乃共同串接於一光敏電阻(CDS),而於該光敏電阻之地端則另接至一彈簧開關之一接點,該彈簧開關乃串接一電阻後接地;利用該光敏電阻之感光偵測暨彈簧開關受行車震動以接觸導通等雙重啟動控制結構,以達到預期效果者。 For custom bicycle lights, please refer to the Republic of China Patent Bulletin No. 356790 "Bike flash warning structure improvement", which is a bicycle flash warning structure improvement, especially a structure that automatically starts to generate flash when driving and light is insufficient, and automatically closes when parking or light is sufficient. Mainly having an LED flash driving circuit, and having LEDs (light emitting diodes) connected to the output ends thereof, the negative terminals of the LEDs are connected in series to a photoresistor (CDS), and the ground of the photoresistor Then connected to a contact of a spring switch, the spring switch is connected in series with a resistor and grounded; the photosensitive detection and spring switch of the photoresistor are subjected to driving vibration to contact the double start control structure such as conduction to achieve the desired effect By.

然而,該種習用的自行車燈雖可配合環境光線充足與否而自動啟閉閃光效果,然其採用的是以光敏電阻感應環境周遭光線強度,但事實上,光敏電阻僅會感受環境光線亮度的差別,但不能適當的被限制在感應既定距離的照明範圍處,特別是一般行人或機車、自行車騎士等,其主要是以燈體照明前方既定距離的道路,使行人、騎士得以看清前方路況而行進,若是採用該光敏電阻的習用設計,常常會遇到當前方照明範圍、身邊亮度不一致時,光敏電阻不能為機動性的判斷,而且該習用的自行車燈只有燈光自動啟閉的兩種模式,但無法因應照明區域的環境亮度而補強、降低照明亮度,致使容易發生下列狀況: However, although the conventional bicycle light can automatically turn on and off the flashing effect in accordance with whether the ambient light is sufficient or not, the photosensitive light is used to sense the ambient light intensity, but in fact, the photoresistor only feels the ambient light brightness. Differences, but not properly limited to the illumination range that senses a given distance, especially for pedestrians, locomotives, cyclists, etc., which are mainly used to illuminate the road at a given distance in front of the lamp body, so that pedestrians and knights can see the road ahead. However, if the conventional design of the photoresistor is used, it is often encountered that the current illumination range and the brightness of the side are inconsistent, the photoresistor cannot be judged for maneuverability, and the conventional bicycle lamp has only two modes of automatic opening and closing of the light. However, it is not possible to reinforce and reduce the brightness of the illumination in response to the ambient brightness of the illuminated area, resulting in the following conditions:

1、該習用自行車燈不能及時對照明區域(即行進前5-10m區域)補強燈光而造成行進危險。 1. The conventional bicycle light can not reinforce the lighting in the lighting area (ie, 5-10m before the travel) and cause danger of travel.

2、又或是不能因應於燈光投射區之環境亮度,而適當降低發光強度,而造成浪費自行車燈電力的問題。 2. It is also impossible to appropriately reduce the luminous intensity according to the ambient brightness of the light projection area, which causes a problem of wasting the power of the bicycle lamp.

3、而且該種自行車燈只能依光敏電阻的感應結果,作啟閉閃光的效果,但不具因應照明區域的環境亮度以調整照明亮度的功能,因此該自行車燈必須安裝較高容量的電池,以維持自行車燈的續航力,而又為了製造成本考量,高容量電池的體積都具有相當尺寸,故該自行車燈不能有效的節省電池電力,也不能在設計上適當縮限電池的體積。 3, and the bicycle light can only be used as a result of the induction of the photoresistor, but does not have the function of adjusting the illumination brightness in response to the ambient brightness of the illumination area. Therefore, the bicycle lamp must be equipped with a higher capacity battery. In order to maintain the endurance of the bicycle light, and for the sake of manufacturing cost, the volume of the high-capacity battery has a considerable size, so the bicycle lamp can not effectively save battery power, and can not properly reduce the size of the battery in design.

緣上述習用自行車燈不能因應照明區域的環境亮度而補強、降低照明亮度,以及不能節省電力等缺失,本發明人認有必要加以改良,應設計一種能因應照明區域的環境亮度而調整照明強度,並兼具節省電力功能的燈體結構,因而發明如附件一之發明。 The above-mentioned conventional bicycle light cannot be reinforced according to the ambient brightness of the illumination area, the illumination brightness is lowered, and the power and the like cannot be saved. The inventors have identified that it is necessary to improve the illumination intensity according to the ambient brightness of the illumination area. And the lamp body structure which has the function of saving electricity, and thus the invention of the invention is attached.

惟,發明人在做實驗時,發現上述附件一之發明仍有精確度不夠的缺失,原因是集光單元(2)係感應光線投射區域(5)的環境光線亮度,但由於集光單元(2)係設置於燈體(1)內(如第一圖之所示),且燈體(1)並設有反射杯(11),因此當燈體(1)之發光單元(3)在發光時,該集光單元(2)可能收到燈體(1)內發光單元(3)之發射光(A)、反射杯所反射的反射光(B)及燈體附近外的光線(C)的影響而使微控制單元誤判,因此會產生與實際上相當之誤差,也就是說集光單元(2)無法正確地反應光線投射區域(5)的環境光線亮度(再如第二圖之所示,其中實線代表微控制單元之判斷亮度及電流,而虛線表示實際光線投射區域之亮度及電流),因此使得發光單元發光時可能會補的不足或超出,而有亮度不足或超亮的狀 況,實有再加以改善的空間,為此發明人秉於精益求精、追求卓越的精神再續研發而得本案之發明,而更具實用性。 However, when the inventor did the experiment, it was found that the invention of the above-mentioned Annex 1 still lacked the accuracy, because the light collecting unit (2) sensed the ambient light brightness of the light projection area (5), but due to the light collecting unit ( 2) is disposed in the lamp body (1) (as shown in the first figure), and the lamp body (1) is provided with a reflector cup (11), so when the light unit (3) of the lamp body (1) is When illuminating, the light collecting unit (2) may receive the emitted light (A) of the light emitting unit (3) in the lamp body (1), the reflected light (B) reflected by the reflecting cup, and the light outside the vicinity of the lamp body (C). The influence of the micro control unit is misjudged, so there is an error corresponding to the actual, that is, the light collecting unit (2) cannot correctly reflect the ambient light brightness of the light projection area (5) (again as the second figure) As shown, where the solid line represents the brightness and current of the micro control unit, and the dotted line represents the brightness and current of the actual light projection area, the light unit may be insufficient or exceeded when illuminated, and the brightness is insufficient or super bright. Shape In this case, there is room for improvement. For this reason, the inventor has invented the invention of the case in the spirit of excellence and the pursuit of excellence, and it is more practical.

其後由脈寬調制單元24調控發光單元3發出對應該差值的亮度,據以對應光線投射區域5處的環境亮度增加或降低發光亮度,因此該上述集光單元2的組成及作用係以差分放大單元21感應並放大對光線投射區域5探得的光線強度,而模數轉換單元22、微控制單元23係傳輸並運算內建環境亮度與光線投射區域5的環境亮度差值,經由脈寬調制單元24命令發光單元3對光線投射區域5照射對應差值的補強或降低環境亮度(差分放大單元21、模數轉換單元22可提供更為精確的感應、運算效果)。 Thereafter, the pulse width modulation unit 24 regulates the brightness of the light-emitting unit 3 corresponding to the difference, thereby increasing or decreasing the brightness of the light corresponding to the ambient light at the light-projecting area 5. Therefore, the composition and function of the light collecting unit 2 are The differential amplifying unit 21 senses and amplifies the intensity of the light detected by the ray casting region 5, and the analog-to-digital conversion unit 22 and the micro-control unit 23 transmit and calculate the difference between the ambient brightness of the built-in environment and the illuminating region 5, via the pulse. The wide modulating unit 24 commands the illuminating unit 3 to illuminate the ray casting region 5 with the corresponding difference or reduce the ambient brightness (the differential amplifying unit 21 and the analog to digital converting unit 22 can provide more accurate sensing and operation effects).

以及,該集光單元2進一步包括一緩衝單元25,該緩衝單元25具有預設之緩衝數值,當集光單元2感測光線投射區域5方向的亮度改變時間在緩衝數值之下時,其會經微控制單元23、脈寬調制單元24命令發光單元3不需要調整發光亮度,讓本發明遇光線投射區域5為環境亮度短時間閃滅時,集光單元2命令發光單元3不需調整發光亮度而避免造成本發明動輒閃爍的狀態。 And the concentrating unit 2 further includes a buffer unit 25 having a preset buffer value. When the concentrating unit 2 senses that the brightness change time in the direction of the ray casting area 5 is below the buffer value, When the micro-control unit 23 and the pulse width modulation unit 24 command the light-emitting unit 3 to adjust the light-emitting brightness, the light-collecting unit 2 commands the light-emitting unit 3 to adjust the light-emitting unit 3 when the light-emitting area 5 of the present invention is flashed for a short time. The brightness is avoided to cause the state of the present invention to flicker.

而感測光線投射區域5方向的亮度改變時間在緩衝數值之上時,緩衝單元25判斷光線投射區域5處有顯著、非短暫性的亮度改變,使緩衝單元25配合微控制單元23會將亮度改變時間與亮度的數值為整合計算,經微控制單元23、脈寬調制單元24命令發光單元3增加或降低發光亮度,因此本發明有下列特點: When the brightness change time in the direction of the sensing light projection area 5 is above the buffer value, the buffer unit 25 determines that there is a significant, non-transitory brightness change at the light projection area 5, so that the buffer unit 25 cooperates with the micro control unit 23 to increase the brightness. The value of changing the time and the brightness is an integrated calculation, and the micro-control unit 23 and the pulse width modulation unit 24 command the light-emitting unit 3 to increase or decrease the light-emitting brightness. Therefore, the present invention has the following features:

1、本發明是由集光單元2感應光線投射區域5的環境亮度值,並由集光單元2運算內建環境光線亮度值與前述數值的差異,並據該數值命令發光單元3補強或降低光線投射區域5的環境亮度;而特別的是集光單元在接收投射區域之環境亮度時,該脈寬調制單元之電流輸出為0(即使得發光單元為不發光之時),藉此而使得集光單元在接收環境亮度時,其燈體內無任何光亮度,因而可以準確地測得投射區域5的環境亮度,有效地因應光線投射區域5的亮度狀況而機動調整燈體1的投射亮度,達到最精準的補光裝置。 1. The present invention senses the ambient brightness value of the light projection area 5 by the light collecting unit 2, and calculates the difference between the built-in ambient light brightness value and the aforementioned value by the light collecting unit 2, and commands the light emitting unit 3 to reinforce or lower according to the value. The ambient brightness of the light projecting area 5; and in particular, when the light collecting unit receives the ambient brightness of the projected area, the current output of the pulse width modulation unit is 0 (ie, when the light emitting unit is not emitting light), thereby When receiving the ambient brightness, the light collecting unit does not have any light brightness in the lamp body, so that the ambient brightness of the projection area 5 can be accurately measured, and the projection brightness of the lamp body 1 can be dynamically adjusted according to the brightness condition of the light projection area 5, Achieve the most accurate fill light device.

2、藉由前述本發明可配合光線投射區域5的亮度狀況而機動調整燈體1的投射亮度特性,因此本發明安裝在燈體1內的電源可以設計以適當容量、體積者,第一可以減少電池體積的占量而減輕燈體1重量及燈體1設計體積,第二可以讓電池的續航力增加,不會如習用結構不能調整亮度下,而發生實際上不須輔以照明而浪費電力的問題。 2. The present invention can be used to adjust the projection brightness characteristic of the lamp body 1 in accordance with the brightness condition of the light projection area 5. Therefore, the power source installed in the lamp body 1 of the present invention can be designed with appropriate capacity and volume. Reducing the volume of the battery to reduce the weight of the lamp body 1 and the design volume of the lamp body 1, and the second can increase the battery life of the battery, and it is not possible to adjust the brightness as in the conventional structure, and the power is actually not required to be supplemented by illumination. The problem.

3、藉由緩衝單元25的增設,其使光線投射區域5遇逢短暫的光線閃滅時,發光單元3不會即刻補充或降低亮度,避免 本發明對應光線的閃滅產生不必要的閃爍狀態,讓使用者不會受到明亮急速變化的困擾,僅在緩衝單元25能確認光線投射區域5為具有相當穩定性、確定性的變化後,始令發光單元3補充或降低亮度,符合實際上對使用者理想視距內提供穩定照明的功效。 3. By the addition of the buffer unit 25, when the light projection area 5 flashes a short time, the light-emitting unit 3 does not immediately replenish or reduce the brightness, thereby avoiding The flashing of the corresponding light of the present invention generates an unnecessary flicker state, so that the user is not plagued by the rapid change of brightness, and only after the buffer unit 25 can confirm that the light projection area 5 has a relatively stable and deterministic change. The illumination unit 3 is supplemented or reduced in brightness, in accordance with the effect of actually providing stable illumination within the user's ideal line of sight.

4、車輛在市區、郊區所需的光照度勢必不同,市區由於路燈、人為活動原因,光源較為充足,而郊區路燈密度較低,導致環境相當昏暗,因此使用本發明於車輛上時,其集光單元2可根據對光線投射區域5的感測結果,在市區發出較低的照明量即可辨認前方路況,而郊區即要較高的照明量才能安全行駛。 4. The illuminance required by vehicles in urban areas and suburbs is bound to be different. Due to street lamps and human activities, the light source is sufficient, and the density of suburban street lamps is low, resulting in a relatively dim environment. Therefore, when using the present invention on a vehicle, The light collecting unit 2 can recognize the front road condition by emitting a lower illumination amount in the urban area according to the sensing result of the light projection area 5, and the suburbs need a higher illumination amount to drive safely.

第六圖係本發明投射區環境亮度等級-時間、驅動電流值等級-時間、燈光投射區亮度等級-時間的曲線圖,該所述之投射區環境亮度等級是指環境給予投射區的亮度值,而驅動電流值等級指當本發明實施於電子機械上時,電子機械對應發光亮度的驅動電流值,而燈光投射區亮度等級則指投射區受到光線投射與環境亮度的總和值,故在該第六圖中可見到,投射區(可對應本發明之光線投射區域5)環境亮度等級較低時,發光單元3應補上較高的投射亮度,當然驅動電流值也會提高,但發光單元3補上投射亮度配上投射區環境亮度的結果,仍是讓燈光投射區的亮度總值保持在預設的恆定值處,且其所有的數值亦較實際值接近。 The sixth figure is a graph of ambient brightness level-time, driving current value level-time, light projection area brightness level-time of the projection area of the present invention, and the projected area ambient brightness level refers to the brightness value given to the projection area by the environment. The driving current value level refers to the driving current value of the electro-mechanical corresponding brightness when the invention is implemented on the electronic machine, and the brightness level of the light projection area refers to the sum of the light projection and the ambient brightness of the projection area, so It can be seen in the sixth figure that when the projection area (corresponding to the light projection area 5 of the present invention) has a low ambient brightness level, the light-emitting unit 3 should be supplemented with a higher projection brightness, and of course the driving current value is also increased, but the light-emitting unit 3 The result of matching the projected brightness with the ambient brightness of the projection area is still to keep the total brightness of the light projection area at a preset constant value, and all the values are close to the actual value.

再如第七圖之所示,本發明之另一實施例係主要在於該集光單元2亦可以為一灰階影像處理器6及其電性連接之微控制單元23,如此而同樣可以將光線投射區域5的影像轉換成一灰階 值,並供微控制單元23判斷該灰階值之亮度或影像,進而調整發光單元3之發光亮度,亦可以達到本案之功效者。 As shown in the seventh embodiment, another embodiment of the present invention is mainly that the light collecting unit 2 can also be a gray scale image processor 6 and the micro control unit 23 electrically connected thereto, so that the same can be The image of the light projection area 5 is converted into a gray scale The value is used by the micro control unit 23 to determine the brightness or image of the grayscale value, thereby adjusting the luminance of the light emitting unit 3, and can also achieve the effect of the present invention.

由上所述者僅用以解釋本發明之較佳實施例,並非企圖具以對本發明作任何形式上之限制,是以,凡有在相同之發明精神下所做有關本發明之任何修飾或變更者,皆仍應包括在本發明意圖保護之範疇內。 The above description is only intended to explain the preferred embodiments of the present invention, and is not intended to limit the invention in any way. The changer should still be included in the scope of the intention of the present invention.
