具体实施方式 Detailed ways

[0022] 本发明提供一种即使灯具的安装方向受限,也能满足照明需求的灯具,其第一实施例如图1所示。 [0022] The present invention provides a mounting direction of the lamp even if limited, but also to meet the needs of lighting fixtures, for example, a first embodiment shown in FIG. 1.

[0023] 本发明的灯具包括光源20、灯座30和反射罩10。 [0023] The present invention includes a light source lamp 20, reflector 10 and socket 30. 反射罩10为一喇叭形的环形曲面,其具有口径小的底部和口径大的开口部,底部端面S12与开口部端面Sll两平面之间的反射罩10的内表面构成了一反射面,用于反射光源20所发出的光线。 A horn reflector 10 is annular surface, an opening portion having a small diameter and large diameter bottom portion, the bottom end surface of the end surface S12 of the opening portion of the inner surface of the reflection cover 10 Sll between two planes constitute a reflection surface, by the reflection light 20 emitted by the light source. 光源20安装在灯座30上,灯座30定位并安装在反射罩10的底部端面S12正中间,使光源20的光轴Z2垂直于底部端面S12,光源20所发出的光线经反射面反射后从开口部出射。 The light source 20 is mounted on the socket 30, the socket 30 is positioned and mounted to the bottom end surface S12 of the positive intermediate reflector 10, optical axis Z2 perpendicular to the light source 20 at the bottom end surface S12, the light source 20 after the light emitted by the reflecting surface emitted from the opening portion.

[0024] 光源20为旋转体结构,旋转体的中心线即为光源20所发出的光线的中心线,即光轴Z2。 [0024] The light source 20 is a rotating structure, the rotating body is the center line of the center line of the light source 20 is emitted, i.e., the optical axis Z2. 对于这样的光源20来说,光轴Z2的方向也即光源20的安装方向。 For such a light source 20, i.e. the optical axis Z2 of the light source 20 of the mounting direction. 当安装方向受限时,光源20的光轴Z2方向和光线照射方向也是一定的,要实现光线照射方向相对安装方向偏移,现有技术的机构无法实现此目的。 When the mounting direction is limited, and the Z2 direction of the optical axis direction of the irradiation light source 20 is constant, the light irradiation to achieve the mounting direction opposite the direction of displacement, the prior art mechanism can not achieve this.

[0025] 解决上述问题的方案是采用非对称型的反射罩,如本实施例所示,反射罩10的反射面具有以下的特征:当用经过光轴Z2的平面将反射面截为两部分,反射面被平面截得的截面包括位于光源20光轴Z2两侧的两段曲线,且此两段曲线不对称。 [0025] The solution to the above problem is to use a non-symmetrical reflector, as shown in this embodiment, the reflecting surface of the reflector 10 has the following characteristics: When a plane passing through the optical axis Z2 of the reflecting surface cut into two parts the reflecting surface is intercepted in the two curves cross-sectional plane includes the optical axis of the light source 20 on either side of Z2, and this two curves are asymmetrical. 也就是说,本发明的反射罩10具有非对称的反射面,其光轴Z2两侧并不相同,使得光线向其中一侧倾斜,则整个光源20的照射方向向一侧倾斜,从而达到调整光线照射方向偏移的效果。 That is, the reflector 10 of the present invention has an asymmetric reflective surface, which optical axes Z2 are not the same on both sides, so that the light inclined toward one side, the entire irradiation direction of the light source 20 is inclined to one side, so as to achieve adjustment light irradiation direction displacement effect.

[0026] 上述非对称的反射面可有多种实现形式,例如图1、图2所示的第一实施例中,反射罩10的反射面是由一条抛物线绕其中轴线Zl旋转180度所扫掠的轨迹形成的抛物面的局部所形成的环形曲面,抛物线的中轴线Zl即为抛物面的中心轴,此环形曲面是指经过抛物面内部的中心轴且在抛物面内部不相交的两个平面之间所夹取的抛物面局部,此两个平面即分别为底部端面S12和开口部端面Sll所在的平面。 [0026] The asymmetric reflective surface may be implemented in many forms, e.g. FIG. 1, a first embodiment illustrated in FIG 2, the reflection surface cover 10 is composed of a parabola in which the axis Zl rotated 180 degrees about the sweep toric paraboloid swept local trajectory forming to be formed, the central axis of the parabola axis Zl is the parabola, is meant that the annular surface between the two planes passing through the center axis of the inner parabolic and paraboloid inside disjoint grippable partial paraboloid, this plane two planar end surfaces, respectively i.e. S12 and Sll end surface of the opening portion located at the bottom. 本实施例中,开口部端面Sll垂直于环形曲面的中轴线Z1,底部端面S12相对倾斜于所述中轴线Z1,开口部端面Sll与底部端面S12之间的夹角为α,α介于O度到90度之间。 In this embodiment, the opening in the end surface perpendicular to the axis Z1 Sll annular surface, bottom end surface S12 inclined relative to the axis Z1, the angle between the end surface of the opening portion and the bottom end surface S12 Sll is α, α between O degrees to 90 degrees between. 此α角也是垂直于底部端面S12 的光源20的光轴Ζ2与抛物面中心轴Zl之间的角度。 This angle α is an angle between the optical axis perpendicular to the parabolic central axis Zl Ζ2 end surface S12 of the light source 20 bottom.

[0027] 当光源20以光轴Ζ2垂直于底部端面S12的方向安装在反射罩10上时,光源20 的光轴Ζ2相对反射面中心轴Zl偏离α角,光线经这种非对称的反射面反射后,将不再以光轴Ζ2为中心地投射出去,光的照射方向将发生改变。 [0027] When the light source 20 to the bottom end surface perpendicular to the optical axis direction Ζ2 S12 is mounted on the reflector housing 10, light source optical axis Ζ2 opposing reflective surface 20 deviates from the central axis Zl angle α, such beam by asymmetric reflective surface after reflection, no longer centered on the optical axis Ζ2 projected out, the irradiation direction of the light will change. [0028] 例如,当需要照射方向偏离光源光轴Ζ230度时,经反复验证和实验可知,α取20 度可以达到所需的照射方向。 [0028] For example, when the light source is necessary to irradiate a direction departing from the optical axis Ζ230 degrees, and after repeated experiments verify understood, [alpha] of 20 degrees can be taken to achieve the desired irradiation direction. 图3示出的是光源20上没有安装本实施例的反射罩10时的配光曲线,由图可知,配光曲线为以光轴Ζ2为中心的对称型曲线。 FIG 3 shows a light distribution does not install the curve 10 at reflector 20 embodiment of the light source, seen from the FIG., As a light distribution curve centered on the optical axis Ζ2 symmetric curve. 图4示出的是光源20上安装有本发明反射罩10时的配光曲线,经安装反射罩10后,整个灯具的光轴Ζ2偏离光源光轴Ζ230度,配光曲线非对称,此时的全角为士60度,半光强角士50度。 FIG. 4 shows a light source mounted on the light distribution curve 20 has a reflector 10 at the time of the present invention, after mounting the reflector 10, of the lamp light source optical axis offset from an optical axis Ζ2 Ζ230 degrees, asymmetrical light distribution curve, then the full angle is ± 60 degrees, a half-intensity angle of 50 degrees with disabilities.

[0029] 经过反复实验得知,光线照射方向与光源光轴Ζ2之间偏离的角度越大,α角也越大。 [0029] After repeated experiments that the greater the deviation between the optical axis of the light source and the light irradiation direction Ζ2 angle, the greater the angle [alpha]. 例如,由上述实施例可知,当光线照射方向需要与光源光轴Ζ2偏离30度时,最佳α角取20度;当偏离角度为10度时,α角最佳取10度;偏离40度时,则α角为35度。 For example, seen from the above embodiment, when the light irradiating direction of the light source 30 necessary to deviate from the optical axis Ζ2, taking the best angle [alpha] of 20 degrees; when the off-angle of 10 degrees, the angle [alpha] of 10 degrees to take the best; deviation from 40 degrees , then the angle α is 35 degrees. 但由于受到制造和实际效果的限制,α角的取值范围通常在0〜35度之间。 However, due to manufacturing limitations and practical results, an angle α ranging between 0 to 35 degrees typically.

[0030] 由于现有的光源通常都是垂直于反射罩10底部端面S12地安装,因此,在制造反射罩10时,只需将反射面为抛物面的常规的对称型反射罩的底部端面S12设计成不与抛物面中心轴Zl垂直,而是设置成与之倾斜一定角度也即上述α角,而光源依然垂直于底部端面S12地安装,即可实现灯具的光线照射方向与光源光轴Ζ2方向偏离。 [0030] Since the conventional light sources are generally perpendicular to the end face of the bottom reflector 10 mounted S12, therefore, when manufacturing the reflector 10, only the bottom end surface of the reflecting surface S12 of a conventional symmetrical design of the parabolic reflector so as not perpendicular to the central axis parabolic Zl, but provided with the above-described inclination angle i.e. the angle α, and the light source is mounted perpendicular to the bottom end surface still S12, the irradiating direction of the light can be implemented with departing from the lamp light source optical axis direction Ζ2 .

[0031] 如图5所示,与第一实施例不同,第二实施例的反射罩10其反射面仍为一条抛物线绕其中轴线Zl旋转180度所扫掠的轨迹形成的抛物面的局部所形成的环形曲面,底部端面S12垂直于环形曲面的中轴线Ζ1,而开口部端面Sll相对底部端面S12成倾斜角δ,此时在底部端面S12垂直安装光源20,则光源20的光轴Zl与中轴线Zl重合。 [0031] As shown in FIG. 5, different from the first embodiment, the reflective surface 10 which cover the second embodiment is still a parabola about an axis Zl wherein rotation trajectory swept 180 degrees parabola formed partially formed annular surface, a bottom end face perpendicular to the center axis S12 Ζ1 annular surface, and an opening bottom end surface opposite end faces Sll to S12 inclination angle [delta], this time at the bottom of the vertical end surface mounted light source 20 is S12, the optical axis of the light source with the Zl 20 axis coincides with Zl.

[0032] 如图6所示,在第三实施例中,反射罩10的反射面同样为一条抛物线绕其中轴线Zl旋转180度所扫掠的轨迹形成的抛物面的局部所形成的环形曲面,其开口部端面Sll和所述底部端面S12相互平行,且均相对于所述中轴线Zl倾斜,底部端面S12用于安装光源的中垂线也即光轴Ζ2的位置与环形曲面的中轴线Zl之间成角度β。 [0032] As shown in FIG 6, in the third embodiment, the reflection surface cover 10 which likewise a parabola about an axis Zl toric rotation trajectory swept 180 degrees locally formed parabola is formed, which a bottom end surface of the opening end surfaces S12 and Sll are mutually parallel, and are relative to the tilt axis Zl, for mounting the bottom end surface S12 of the light source that is perpendicular to the optical axis position of the toric Ζ2 axis Zl of the between an angle β.

[0033] 采用图5、6所示的第二、第三实施例,无论光源的光轴Ζ2是否偏离反射面的中轴线Ζ1,由于光源两侧的曲面并不对称,从而使两侧的反射光线不对称,其中一侧的光线向另一侧偏移,进而导致整个灯具的照射方向偏离光轴Ζ2,达到调节照射方向的效果。 Second and third embodiment [0033] A shown in FIG. 5 and 6, regardless of the light source to the optical axis of the reflecting surface deviates Ζ2 axis Ζ1, since both sides of the surface light source and an asymmetric, so that both sides of the reflection asymmetric light, in which light is shifted to the side of the other side, which led to the irradiation direction of the lamp from the optical axis Ζ2, achieve the effect of adjusting the irradiation direction.

[0034] 综上所述,只要光轴Ζ2两侧的反射面不对称,造成其中一侧的光线反射方向向另一侧偏移,从而实现反射面反射光线也偏离某一角度,使得最终的照射方向偏离光源光轴τι。 [0034] In summary, as long as both sides of the reflecting surfaces of the optical axis Ζ2 asymmetric, resulting in the reflection direction in which light is shifted to the side of the other side, in order to achieve light reflection surface deviate from an angle, such that the final direction deviation of the optical axis of the irradiation light τι.

[0035] 由于不同功率的光源尺寸差异较大,光源的位置和发光部位尺寸变化会影响反射面的反射效果,并影响配光曲线的形状。 [0035] Since the light source power is large size differences, the position and size of the light emitting portion of the light source changes will affect the reflection effect of the reflecting surface, and the influence the shape of the light distribution curve. 因此,考虑到反射罩对不同光源类型(例如不同长度的电弧管光源)的配光曲线的兼容性,同时也为使灯具具备防眩功能,反射面设计为反射率大于85%的表面,使光束经反射面反射后发散。 Therefore, in consideration of the compatibility of different reflector types of light sources (e.g. light sources of different lengths of arc tube) of the light distribution curve, but also for the lamp is provided with an antiglare function, reflective surface reflectance of the surface of greater than 85%, so that after the divergent light flux reflecting surface.

[0036] 与现有技术相比,本发明的灯具及其反射罩10,在不改变光源安装方向和位置的情况下,由于安装后的光源两侧的反射面不对称,实现了灯具的光线照射方向与光源光轴即安装方向的偏离, 满足相应照明条件下的照明需求。 [0036] Compared with the prior art, the lamp cap and the reflector 10 of the present invention, without changing the mounting direction and position of the light source, since the light reflecting surface on both sides of asymmetrical after installation, to achieve a lamp light i.e., the irradiation direction of the light source mounting axis direction of the deviation, the lighting needs of the respective lighting conditions. 并且采用反射率大于85%的反射面, 还可兼容多种功率的光源,减少眩光。 And using the reflective surface of greater than 85%, also compatible with a variety of power sources to reduce glare.

[0037] 上面结合附图对本发明的实施例进行了描述,但是本发明并不局限于上述的具体实施方式,上述的具体实施方式仅仅是示意性的,而不是限制性的,本领域的普通技术人员在本发明的启示下,在不脱离本发明宗旨和权利要求所保护的范围情况下,还可做出很多形式,这些均属于本发明的保护之内。 , Binding of ordinary [0037] The above drawings, embodiments of the present invention have been described, but the present invention is not limited to the specific embodiments described above specific embodiments are merely illustrative, and not restrictive the art in light of the present invention, the scope of the present invention without departing from the spirit and the protection of the claims, can also make many of these fall within the protection of the present invention.
