Description
本發明涉及一種照明裝置，尤其涉及一種具有防眩光功能的路面照明裝置。 The invention relates to a lighting device, in particular to a road lighting device with anti-glare function.
眩光(glare)作為一種光害，一般包括直接眩光與間接眩光。直接眩光是指來自視場中高亮度或沒有充分遮蔽的眩光源/發光物發出的光線直接對眼睛造成的刺激，眩光源發光物處於被觀察物的同一方向或鄰近方向。間接眩光是指眩光源處於非觀察方向產生的眩光，通常由高度光滑的表面的反射光引起。如圖1所示，當光源101位於人眼102上方時，自人眼102所在垂直面103偏轉45度至85度之間的範圍內，光源101會對人眼102造成直接眩光。 Glare is a kind of light damage, which generally includes direct glare and indirect glare. Direct glare refers to the direct stimulation of the eye from the light emitted by the glare source/illuminator with high brightness or insufficient shielding in the field of view. The glare source illuminant is in the same direction or adjacent direction of the object to be observed. Indirect glare refers to the glare produced by a glare source in a non-observing direction, usually caused by reflected light from a highly smooth surface. As shown in FIG. 1, when the light source 101 is positioned above the human eye 102, the light source 101 causes direct glare to the human eye 102 from a range in which the vertical plane 103 of the human eye 102 is deflected between 45 degrees and 85 degrees.
如圖2所示，路燈201發出的光線以其自身為中心向路面進行投射，先前技術中可實現路燈201在車輛行駛的X方向上的輻射範圍大於與X方向垂直的Y方向的輻射範圍，以有效地提高路燈201的光利用率。然而，路燈201在X方向上形成的輻射範圍是以路燈201為中心對稱分佈地，即路燈201在X方向上向其兩側的輻射角θ1與θ2相等，通常θ1=θ2=70度，這會對人眼產生直接眩光，在此，輻射角亦可稱為半峰邊角(half-peak side angle)，是指以垂直路面為中心向左右兩側量測最大光強度的一半所得的角度，也就是光源所發出的發光強度為平面上最大發光強度的50%的光線與垂直線的夾角。在此，可參見 圖3所示路燈201的配光曲線，圖中A點對應光線的光強度為該路燈201在0度到90度中最大光強度的50%，B點對應光線的光強度為該路燈201在0度到90度中的最大光強度，路燈201的輻射角約等於70度。由此可見，現有的路燈照明裝置還是會對駕駛者的眼睛造成直接眩光。 As shown in FIG. 2, the light emitted by the street lamp 201 is projected toward the road surface centering on itself. In the prior art, the radiation range of the street lamp 201 in the X direction of the vehicle traveling is greater than the radiation range in the Y direction perpendicular to the X direction. In order to effectively improve the light utilization rate of the street lamp 201. However, the radiation range formed by the street lamp 201 in the X direction is symmetrically distributed around the street lamp 201, that is, the radiation angles θ1 and θ2 of the street lamp 201 to the both sides thereof in the X direction are equal, usually θ1 = θ2 = 70 degrees, which will Direct glare is generated to the human eye. Here, the radiation angle may also be referred to as a half-peak side angle, which is an angle obtained by measuring half of the maximum light intensity from the vertical road surface to the left and right sides. That is, the angle between the light emitted by the light source and the vertical line is 50% of the maximum luminous intensity on the plane. Here, see The light distribution curve of the street lamp 201 shown in FIG. 3, the light intensity of the light corresponding to the point A in the figure is 50% of the maximum light intensity of the street lamp 201 in the range of 0 to 90 degrees, and the light intensity of the point B corresponding to the light is the street lamp 201. The maximum light intensity in the range of 0 to 90 degrees, the radiation angle of the street lamp 201 is approximately equal to 70 degrees. It can be seen that the existing street lighting device still causes direct glare to the driver's eyes.
故，有必要提供一種具有防眩光功能的路面照明裝置。 Therefore, it is necessary to provide a road lighting device with anti-glare function.

Moreover, the solar cell encapsulated in the light-transmissive package directly converts sunlight into electrical energy and stores the electrical energy in the power storage device, thereby facilitating nighttime power storage. The power supply is provided to the light-emitting diode for use as road lighting, so that the road lighting device has the effect of energy saving and environmental protection.
下面將結合附圖，以對本發明實施例作進一步地詳細說明。 The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
參見圖4，本發明第一實施例提供的一種路面照明裝置10，其用於對路面11進行照明，該照明裝置10包括一個光源12，一個電力儲存裝置13，一個太陽能電池14，一個透光封裝體15。 Referring to FIG. 4, a road lighting device 10 according to a first embodiment of the present invention is used for illuminating a road surface 11.

光源12包括一個發光二極體121及一個光學元件122。 The light source 12 includes a light emitting diode 121 and an optical element 122.
發光二極體121為白光發光二極體或高功率發光二極體，當然亦可為紅光、藍光等其他可發出不同色光的發光二極體。 The light-emitting diode 121 is a white light-emitting diode or a high-power light-emitting diode, and may of course be a light-emitting diode that emits different colors such as red light or blue light.
光學元件122與發光二極體121光學耦合，即發光二極體121發出的光線直接進入光學元件122，並經由光學元件122的光學作用射出。在本實施例中，光源12設置於路面11上，發光二極體121發出的光線向上射出至光學元件122中，光學元件122用於使發光二極體121發出的光線偏折向該光源12的側向並沿路面11的延伸方向X出射。 The optical element 122 is optically coupled to the light emitting diode 121, that is, the light emitted by the light emitting diode 121 directly enters the optical element 122 and is emitted through the optical action of the optical element 122. In the present embodiment, the light source 12 is disposed on the road surface 11 , and the light emitted by the light-emitting diode 121 is emitted upward into the optical element 122. The optical element 122 is used to deflect the light emitted by the light-emitting diode 121 to the light source 12 .

Optical element 122 includes a funnel-shaped top surface 1221 and a vertical side wall 1222. The light emitting diode 121 is disposed at a geometric center of the bottom of the optical element 122 opposite to the top surface 1221. The top surface 1221 is a quadric surface. In this embodiment, the top surface 1221 is a parabolic surface. From light The light emitted by the diode 121 is mainly directed toward the top surface 1221, and total internal reflection (TIR) occurs at the top surface 1221 and is emitted through the vertical sidewall 1222 at an angle of almost 90 degrees to the longitudinal axis 1220. Light rays that are directed from the LEDs 121 directly toward the vertical sidewalls 1222 are emitted through the vertical sidewalls 1222 at a slight angle from the vertical direction of the longitudinal axis 1220. Therefore, the light emitted through the optical element 122 may deviate from the extending direction of the road surface 11 by a slight angle, that is, the angle θ between the light emitted through the optical element 122 and the road surface 11 is within a predetermined range, for example, -30 degrees ≦θ. ≦+30 degrees, here, the angle θ refers to the angle between the light emitted through the optical element 122 and the light intensity of 50% of the maximum luminous intensity on the plane and the road surface 11. In addition, a reflective layer 1223 may be disposed on the top surface 1221 of the optical element 122 to further improve the reflection efficiency.
電力儲存裝置13，例如電池，與發光二極體121電性連接。電力儲存裝置13用於儲存電能，並能夠提供電力給發光二極體121。 The power storage device 13, such as a battery, is electrically connected to the light emitting diode 121. The power storage device 13 is for storing electrical energy and is capable of supplying power to the light emitting diode 121.

透光封裝體15設置於路面11上，並且光源12與太陽能電池14包覆於透光封裝體15中。在本實施例中，透光封裝體15具有截頂圓錐形輪廓，其具有一頂面151及一環繞該頂面151的側面152。該光源12位於透光封裝體15的底部，而太陽能電池14與該光源12相對地設置於透光封裝體15的頂部且鄰近於頂面151，這樣有利於太陽能電池14直 接吸收太陽光，提高了太陽能電池14的吸收效率。透光封裝體15的材質主要由硬度與透光率較高的材料制得，例如強化玻璃，石英，水晶，藍寶石(Sapphire)等，這樣可有效地防止該照明裝置10受到較大外力作用而破損，例如車輛的碾壓。 The light transmissive package 15 is disposed on the road surface 11 , and the light source 12 and the solar cell 14 are covered in the light transmissive package 15 . In the present embodiment, the light transmissive package 15 has a truncated conical profile having a top surface 151 and a side surface 152 surrounding the top surface 151. The light source 12 is located at the bottom of the transparent package 15 , and the solar cell 14 is disposed opposite to the light source 12 at the top of the transparent package 15 and adjacent to the top surface 151 , which is advantageous for the solar cell 14 The absorption of sunlight increases the absorption efficiency of the solar cell 14. The material of the light-transmissive package 15 is mainly made of a material having high hardness and light transmittance, such as tempered glass, quartz, crystal, sapphire, etc., so that the illuminating device 10 can be effectively prevented from being subjected to a large external force. Damage, such as rolling of a vehicle.
在本實施例中，發光二極體121發出的光線經由光學元件122射出並直接進入透光封裝體15中，最後由透光封裝體15射出以照明路面11。同時，經由光學元件122出射的光線與路面11之間的夾角θ大於等於-30度或小於等於+30度，並且透光封裝體15的折射率大於1，故由透光封裝體15射出且進入空氣的光線與路面11之間的夾角θ仍然可達到大於等於-30度或小於等於+30度。故，路面照明裝置10發出的強光絕大部分射向路面11，而不會直接對車輛駕駛員產生直接眩光的影響。 In the present embodiment, the light emitted by the light-emitting diode 121 is emitted through the optical element 122 and directly enters the light-transmitting package 15 , and is finally emitted by the light-transmitting package 15 to illuminate the road surface 11 . At the same time, the angle θ between the light emitted through the optical element 122 and the road surface 11 is greater than or equal to -30 degrees or less than or equal to +30 degrees, and the refractive index of the light-transmitting package 15 is greater than 1, so that the light-transmitting package 15 is emitted and The angle θ between the light entering the air and the road surface 11 can still be -30 degrees or more or +30 degrees or less. Therefore, most of the strong light emitted by the road lighting device 10 is directed to the road surface 11 without directly affecting the driver of the vehicle.
另，第一實施例中光源12所包括的光學元件的結構並不限於此，還可採用其他設計以使得光源12發出的光線與路面11之間的夾角θ在一預定範圍內，以下將舉例說明幾種具有不同光學元件的光源。 In addition, the structure of the optical element included in the light source 12 in the first embodiment is not limited thereto, and other designs may be employed such that the angle θ between the light emitted from the light source 12 and the road surface 11 is within a predetermined range, which will be exemplified below.

Light rays emitted from the LEDs 321 are mainly directed toward the top surface 3221, and are totally reflected at the top surface 3221 and are emitted at an angle of almost 90 degrees to the longitudinal axis 3220. Light rays that are directed from the LEDs 321 directly toward the vertical side 3222 are also emitted at an angle of approximately 90 degrees to the longitudinal axis 3220. Therefore, most of the light emitted through the optical element 322 is parallel to the extending direction of the road surface 11, and a small portion deviates from the extending direction of the road surface 11 by a slight angle, that is, the angle between the light emitted through the optical element 322 and the road surface θ. In a predetermined range, for example, -25 degrees ≦ θ ≦ + 25 degrees, where the angle θ refers to the angle between the light emitted through the optical element 122 and the light intensity of 50% of the maximum luminous intensity on the plane and the road surface 11 .

Light reflected by the outer surface 4224 may enter the top portion 4222 or be reflected again and exit through the outer surface 4224. Light entering the top portion 4222 is totally reflected at the top surface 4225 and exits through the vertical sidewalls 4226 at an angle of approximately 90 degrees to the longitudinal axis 4220.

參見圖10，本發明第五實施例提供的一種路面照明裝置50，其用於對路面11進行照明，該照明裝置50與上述第二實施例所提供的路面照明裝置20基本相同，不同之處在於基板56進一步包括一個用於收容電力儲存裝置13的容置座561，容置座561設置於該基板56的與光源12相對的一側且能夠***路面11中以將該照明裝置50固定。光源12設置於透光封裝體55的中心位置，而太陽能電池54與該光源12位於基板56的同一側且太陽能電池54設置於該光源12的四周以環繞該光源12，從而有效地降低了路面照明裝置50相對於地面11的高度，在對路面11進行有效照明的同時減小了對路面11上車輛的阻礙。 Referring to FIG. 10, a road lighting device 50 according to a fifth embodiment of the present invention is used for illuminating a road surface 11. The lighting device 50 is substantially the same as the road surface lighting device 20 provided by the second embodiment, and the difference is the same. The substrate 56 further includes a receiving seat 561 for accommodating the power storage device 13. The receiving seat 561 is disposed on a side of the substrate 56 opposite to the light source 12 and can be inserted into the road surface 11 to fix the lighting device 50. The light source 12 is disposed at a central position of the light transmissive package 55, and the solar cell 54 and the light source 12 are located on the same side of the substrate 56. The solar cell 54 is disposed around the light source 12 to surround the light source 12, thereby effectively reducing the road surface. The height of the illuminating device 50 relative to the ground 11 reduces the obstruction to the vehicle on the road surface 11 while effectively illuminating the road surface 11.
