下面参照附图详细描述本发明实施例的机场灯标。The airport beacon of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
参照图1至图7所示,根据本发明实施例提供的机场灯标,可以用于民用机场、军用机场、直升机机场等场所,作为机场的特种助航设备,主要用于给空中航空器指示机场位置以及全部或部分供飞机起飞、着陆和表面活动使用的场地或构筑物上的特定区域,其包括电源箱10、底座20、灯罩30、上盖50及LED发光单元40。Referring to FIG. 1 to FIG. 7 , an airport beacon provided according to an embodiment of the present invention can be used in a civil airport, a military airport, a helicopter airport, etc., as a special navigation aid for an airport, and is mainly used to indicate an airport to an airborne aircraft. The location and all or part of a particular area on the site or structure for aircraft take-off, landing, and surface activity includes a power box 10, a base 20, a shade 30, an upper cover 50, and an LED lighting unit 40.
具体的,电源箱10内设有驱动控制板11,底座20设置于所述电源箱10上且可沿竖向周向旋转预定角度。灯罩30安装于所述底座20上,上盖50安装于所述灯罩上端并与所述灯罩和底座共同限定出密闭的收容腔。LED发光单元40装设于所述收容腔内,并与所述驱动控制板11电连接,以在所述驱动控制板11的驱动下工作。Specifically, the power supply box 10 is provided with a driving control board 11 disposed on the power box 10 and rotatable in a vertical direction by a predetermined angle. The lamp cover 30 is mounted on the base 20, and the upper cover 50 is mounted on the upper end of the lamp cover and defines a sealed receiving cavity together with the lamp cover and the base. The LED lighting unit 40 is mounted in the receiving cavity and is electrically connected to the driving control board 11 to operate under the driving of the driving control board 11.
根据本发明实施例提供的机场灯标,采用LED发光单元40作为光源,灯具效率高,
光源寿命长,维护成本低,节能环保。此外,底座20设置于电源箱10上且可沿竖向周向旋转预定角度,也即是LED发光单元40可以旋转预定角度,如此,可以实现LED发光单元40角度的调节,可以满足不同方位观测。According to the airport beacon provided by the embodiment of the present invention, the LED lighting unit 40 is used as the light source, and the lamp is highly efficient.
Long life of light source, low maintenance cost, energy saving and environmental protection. In addition, the base 20 is disposed on the power box 10 and can be rotated by a predetermined angle in the vertical direction, that is, the LED lighting unit 40 can be rotated by a predetermined angle. Thus, the angle of the LED lighting unit 40 can be adjusted to meet different orientation observations. .
可选地,底座20及电源箱10可以采用金属材质,例如底座20采用铝合金材质,其结构强度高,耐腐蚀,能够适应室外恶劣的自然环境,同时,也具有良好的热传导性能,可以将LED发光单元40的热量快速传递至外部,加快散热,提高散热效果。电源箱10采用不锈钢材质,其结构强度高,耐腐蚀,可以适用室外恶劣自然环境,而且,便于加工。Optionally, the base 20 and the power box 10 can be made of metal. For example, the base 20 is made of aluminum alloy, which has high structural strength, corrosion resistance, can adapt to the harsh outdoor environment, and has good heat conduction performance. The heat of the LED lighting unit 40 is quickly transmitted to the outside, which accelerates heat dissipation and improves heat dissipation. The power box 10 is made of stainless steel and has high structural strength and corrosion resistance. It can be used in outdoor harsh natural environments and is easy to process.
参照图1至图2所示,在本发明的一个实施例中,灯罩30形成为环形筒状,灯罩30上端敞开形成第一敞口,所述灯罩30下端敞开形成第二敞口,所述上盖50密封所述第一敞口,所述底座20密封所述第二敞口,也就是说,灯罩30为环形筒状结构,且上下两端敞开,上盖50可拆卸连接在灯罩30的上端,以密封灯罩30上端的第一敞口,而底座20则可拆卸连接在灯罩30的下端,以密封灯罩30下端的第二敞口,如此,其结构简单,装配方便,而且能够密封形成上述的收容腔,密封效果好。Referring to FIG. 1 to FIG. 2, in one embodiment of the present invention, the lamp cover 30 is formed in an annular cylindrical shape, the upper end of the lamp cover 30 is open to form a first opening, and the lower end of the lamp cover 30 is open to form a second opening. The upper cover 50 seals the first opening, and the base 20 seals the second opening, that is, the lamp cover 30 has an annular cylindrical structure, and the upper and lower ends are open, and the upper cover 50 is detachably connected to the lamp cover 30. The upper end is for sealing the first opening of the upper end of the lamp cover 30, and the base 20 is detachably connected to the lower end of the lamp cover 30 to seal the second opening of the lower end of the lamp cover 30. Thus, the structure is simple, the assembly is convenient, and the seal can be sealed. The above-mentioned receiving cavity is formed, and the sealing effect is good.
有利的,参照图3所示,LED发光单元40包括上固定板402、下固定板403及多个LED光源组件401,多个所述LED光源组件401固定于所述上固定板402、下固定板403之间并围合形成多边形,且各个所述LED光源组件401的出光方向朝向所述灯罩30以形成所述环照光。For example, as shown in FIG. 3, the LED lighting unit 40 includes an upper fixing plate 402, a lower fixing plate 403, and a plurality of LED light source assemblies 401. The plurality of LED light source assemblies 401 are fixed to the upper fixing plate 402 and fixed. The plates 403 are enclosed and formed into a polygonal shape, and the light-emitting directions of the respective LED light source assemblies 401 are directed toward the globe 30 to form the ring illumination.
也就是说,LED发光单元40主要是由上固定板402、下固定板403和多个LED光源组件401组成,其中,多个LED光源组件401围成的多边形结构,并通过上固定板402和下固定板403固定,例如在图3示例中,四个LED光源组件401围合形成四边形结构,如此,四个LED光源组件401分别朝向不同的方向发光,形成周向布置的四个出光面,且射出的光线经过灯罩30射出后呈现环照光效果,进而使得该机场灯标的能够在不同的角度被观测到,其指示效果更好。That is, the LED lighting unit 40 is mainly composed of an upper fixing plate 402, a lower fixing plate 403 and a plurality of LED light source assemblies 401, wherein the plurality of LED light source assemblies 401 are surrounded by a polygonal structure and passed through the upper fixing plate 402 and The lower fixing plate 403 is fixed. For example, in the example of FIG. 3, the four LED light source assemblies 401 are enclosed to form a quadrilateral structure. Thus, the four LED light source assemblies 401 respectively emit light in different directions to form four light emitting surfaces arranged in a circumferential direction. The emitted light passes through the lampshade 30 and exhibits a ring-lighting effect, so that the airport beacon can be observed at different angles, and the indication effect is better.
需要说明的是,本发明不限于此,LED光源组件401的数量可以根据需要配置,例如还可以是五个、六个或者更多LED光源组件401围合形成的多边形结构,例如五个LED光源组件401围合形成五边形结构,六个LED光源组件401围合形成六边形结构,LED光源组件401的数量越多,形成出光面越多,进而形成的环照光效果越好。It should be noted that the present invention is not limited thereto, and the number of the LED light source components 401 may be configured as needed, for example, a polygonal structure formed by enclosing five, six or more LED light source components 401, for example, five LED light sources. The component 401 is enclosed to form a pentagonal structure, and the six LED light source components 401 are enclosed to form a hexagonal structure. The more the number of the LED light source components 401, the more the light surface is formed, and the better the ring light effect is formed.
参照图4所示,在本发明的一具体实施例中,每个所述LED光源组件401包括反光罩4011、条形散热器4012、光源基板4013及多个LED光源4014,条形散热器4012与所述反光罩4011沿前后方向相对固定设置;光源基板4013设置于所述条形散热器4012上;
个所述LED光源4014按照线性阵列布置于所述光源基板4013上,各个所述LED光源4014的发光方向均朝向所述反光罩4011,且各个所述LED光源4014的发光轴心线互相平行,以使所述LED光源4014发出的光通过所述反光罩4011反射后从所述灯罩30射出。Referring to FIG. 4, in an embodiment of the present invention, each of the LED light source assemblies 401 includes a reflector 4011, a strip heat sink 4012, a light source substrate 4013, and a plurality of LED light sources 4014, and a strip heat sink 4012. The light-receiving cover 4011 is relatively fixed in the front-rear direction; the light source substrate 4013 is disposed on the strip-shaped heat sink 4012;
The LED light sources 4014 are arranged on the light source substrate 4013 in a linear array, and the light emitting directions of the LED light sources 4014 are all directed toward the reflector 4011, and the light emitting axis lines of the LED light sources 4014 are parallel to each other. The light emitted from the LED light source 4014 is reflected by the reflector 4011 and then emitted from the globe 30.
例如在图4示例中,条形散热器4012平行设置反光罩4011的前方,该条形散热器4012可以采用铝型材,光源基板4013安装于条形散热器4012的后表面,多个LED光源4014以线性阵列方式布置于所述光源基板4013上,且各个LED光源4014均朝向反光罩4011,如此,当LED光源4014被点亮时,LED光源4014的光线投射至反光罩4011,由于反光罩4011具有光学反射作用,所以投射至反光罩4011上的光,在反光罩4011的反射作用下集中反射至前方,最终从灯罩30射出。For example, in the example of FIG. 4, the strip heat sink 4012 is disposed in parallel with the front of the reflector 4011. The strip heat sink 4012 may be an aluminum profile. The light source substrate 4013 is mounted on the rear surface of the strip heat sink 4012, and the plurality of LED light sources 4014. Arranged on the light source substrate 4013 in a linear array manner, and each of the LED light sources 4014 is directed toward the reflector 4011. Thus, when the LED light source 4014 is illuminated, the light of the LED light source 4014 is projected to the reflector 4011 due to the reflector 4011. Since it has an optical reflection effect, the light projected onto the reflector 4011 is concentratedly reflected to the front by the reflection of the reflector 4011, and finally emitted from the globe 30.
换言之,LED光源发出的光通过反光罩4011反射后从灯罩30射出,可以提高光源转换率,而且使得射出的光线更加集中更加均匀,光强更强,能够满足机场指示的高光强要求。In other words, the light emitted by the LED light source is reflected by the reflector 4011 and then emitted from the lamp cover 30, which can improve the conversion rate of the light source, and make the emitted light more concentrated and uniform, and the light intensity is stronger, and can meet the high light intensity requirement indicated by the airport.
更为具体的,参照图4至图5所示,在一个示例中,反光罩4011包括底壁及第一侧壁4011b和第二侧壁4011c,其中,底壁沿左右方向延伸,该底壁包括中心底壁4011a、形成于所述中心底壁4011a上侧的上边缘底壁4011g以及形成于所述中心底壁4011a下侧的下边缘底壁4011h;所述中心底壁4011a形成为向后凸出的弧形,所述上边缘底壁4011g及下边缘底壁4011h形成为直线形或弧形;所述第一侧壁4011b形成于所述底壁的左侧,所述第二侧壁4011c形成于所述底壁的右侧。More specifically, referring to FIG. 4 to FIG. 5, in one example, the reflector 4011 includes a bottom wall and a first side wall 4011b and a second side wall 4011c, wherein the bottom wall extends in the left-right direction, the bottom wall A central bottom wall 4011a, an upper edge bottom wall 4011g formed on an upper side of the central bottom wall 4011a, and a lower edge bottom wall 4011h formed on a lower side of the central bottom wall 4011a; the central bottom wall 4011a is formed to be rearward a convex arc shape, the upper edge bottom wall 4011g and the lower edge bottom wall 4011h are formed in a straight line or an arc shape; the first side wall 4011b is formed on a left side of the bottom wall, the second side wall 4011c is formed on the right side of the bottom wall.
当LED光源发光时,光线投射至反光罩4011的中心底壁4011a、上边缘底壁4011g和下边缘底壁4011h上,经由中心底壁4011a、上边缘底壁4011g和下边缘底壁4011h反射后从灯罩30射出,具体的,由于中心底壁4011a为向后突出的弧形,所以,部分光线经过中心底壁4011a反射后会向中间聚集并形成均匀的反射光线从灯罩30射出。与此同时,另一部分投射至中心底壁4011a上的光线,经过该中心底壁4011a一次反射后,被反射至上边缘底壁4011g或下边缘底壁4011h,再经过上边缘底壁4011g或下边缘底壁4011h的二次反射后聚集形成均匀的反射光线从灯罩30射出。此外,第一侧壁4011b和第二侧壁4011c也起到反射作用,可以将两侧的光反射积聚至中间,并从灯罩30射出。如此,可以提高其反射效果,而且确保光线更集中、更加均匀。When the LED light source emits light, the light is projected onto the central bottom wall 4011a of the reflector 4011, the upper edge bottom wall 4011g, and the lower edge bottom wall 4011h, and is reflected by the center bottom wall 4011a, the upper edge bottom wall 4011g, and the lower edge bottom wall 4011h. Specifically, since the central bottom wall 4011a is an arc that protrudes rearward, part of the light is reflected by the central bottom wall 4011a, and is concentrated toward the center to form uniform reflected light from the globe 30. At the same time, another portion of the light projected onto the central bottom wall 4011a is once reflected by the central bottom wall 4011a, and then reflected to the upper edge bottom wall 4011g or the lower edge bottom wall 4011h, and then passes through the upper edge bottom wall 4011g or the lower edge. The secondary reflection of the bottom wall 4011h is concentrated to form a uniform reflected light that is emitted from the globe 30. Further, the first side wall 4011b and the second side wall 4011c also function as reflections, and the light reflection on both sides can be accumulated in the middle and emitted from the globe 30. In this way, the reflection effect can be improved, and the light is more concentrated and more uniform.
参照图6所示,更为具体的,光源基板4013上印刷有与所述LED光源4014对应的线路及位于所述线路上的LED通电接点和导线通电接点4013a,所述LED光源4014连接在所述LED通电接点上,所述导线通电接点4013a连接有供电导线4015,如此,通过供电导
线4015接入直流电,直流电通过线路提供给各个LED光源4014,使得LED光源4014工作。Referring to FIG. 6 , more specifically, the light source substrate 4013 is printed with a line corresponding to the LED light source 4014 and an LED power contact point and a wire power contact point 4013a on the line. The LED light source 4014 is connected to the device. At the LED energization contact, the wire energizing contact 4013a is connected to the power supply wire 4015, and thus, through the power supply guide
The line 4015 is connected to direct current, and the direct current is supplied to each of the LED light sources 4014 through the line, so that the LED light source 4014 operates.
可选地,反光罩4011可以采用光学级PC材料,具有良好的抗老化抗冲击效果,以便于适应室外的恶劣自然环境。Optionally, the reflector 4011 can be made of optical grade PC material, which has good anti-aging and anti-shock effects, so as to adapt to the harsh natural environment outside.
更为有利的,中心底壁4011a的内表面在上下方向的中间位置形成有沿左右方向延伸的反光棱4011d,所述反光棱4011d与多个所LED光源前后相对,且所述反光棱4011d的纵向截面形成为向靠近所述LED光源的方向突出的三角形。也即是,中心底壁4011a内表面形成的反光棱4011d是向前突出于的,且纵向截面呈三角形。More preferably, the inner surface of the central bottom wall 4011a is formed with a reflective rib 4011d extending in the left-right direction at an intermediate position in the up-and-down direction, the reflective rib 4011d being opposite to the plurality of LED light sources, and the reflective rib 4011d The longitudinal section is formed as a triangle that protrudes in a direction close to the LED light source. That is, the reflecting rib 4011d formed on the inner surface of the center bottom wall 4011a is protruded forward and has a triangular cross section in the longitudinal direction.
由于反光罩4011前方的光源基板4013及条形散热器4012在上下方向上具有一定的宽度,LED光源4014发出的光投射在反光罩4011的底壁,其中部分光线投射至中心底壁4011a上与光源基板4013和条形散热器4012相对的中间位置,这部分光线被中心底壁4011a反射之后,一部分光会被光源基板4013和条形散热器4012阻挡,如此,造成光源损失,光转换率降低,亮度降低等问题。Since the light source substrate 4013 and the strip heat sink 4012 in front of the reflector 4011 have a certain width in the up and down direction, the light emitted from the LED light source 4014 is projected on the bottom wall of the reflector 4011, and part of the light is projected onto the central bottom wall 4011a. The light source substrate 4013 and the strip heat sink 4012 are opposite to each other. After the light is reflected by the central bottom wall 4011a, a part of the light is blocked by the light source substrate 4013 and the strip heat sink 4012. Thus, the light source is lost and the light conversion rate is lowered. , brightness reduction and other issues.
为此,本实施例中,通过在反光罩的中心底壁4011a上设置反光棱4011d,则部分投射至该反光棱4011d上的光线,由于该反光棱4011d的纵向截面是向前突出的三角形,所以,其三角形的两条边所在的平面为斜面S10,通过该斜面S10对这部分光线进行反射,再通过上边缘底壁4011g、下边缘底壁4011h进行二次反射,最终能够避开光源基板4013和条形散热器4012并从灯罩30射出。换言之,部分投射至反光棱4011d上的光线,通过两次反射最终能够出从灯罩30射出,如此,可以降低光源损失,进一步提高光转换率,增强了光强。To this end, in the present embodiment, by providing the reflecting edge 4011d on the central bottom wall 4011a of the reflector, the light that is partially projected onto the reflecting edge 4011d is a triangular shape that protrudes forward because the longitudinal section of the reflecting edge 4011d is Therefore, the plane where the two sides of the triangle are located is the inclined surface S10, and the portion of the light is reflected by the inclined surface S10, and then the secondary reflection is performed through the upper edge bottom wall 4011g and the lower edge bottom wall 4011h, thereby finally avoiding the light source substrate. 4013 and a strip radiator 4012 are ejected from the globe 30. In other words, the light partially projected onto the reflecting edge 4011d can be finally emitted from the globe 30 by two reflections, so that the light source loss can be reduced, the light conversion rate can be further increased, and the light intensity can be enhanced.
可以理解的是,三角形的两条边所在的平面可以为平面、也可以为弧形面,具体可以根据需要设置。It can be understood that the plane where the two sides of the triangle are located may be a plane or a curved surface, and may be set as needed.
