For those skilled in the art, without any creative effort, other embodiments obtained from the drawings and examples shall belong to the technical solution disclosed by the present invention.

Example one

As shown in fig. 3 and 4, it is a schematic view of the bus illumination principle of the light reflection component of the embodiment of the present invention. A lamp holder comprises a lamp holder 1 and an integrally detachable light source module 2 consisting of a heat dissipation top cover 21, a light emitting component 22, a lampshade 23 and a reflecting component 24. The light reflecting component 24 is a trumpet-shaped (with a horn mouth facing the lamp holder) revolving body, and a generatrix 241 of the revolving body is a curve expressed by a quarter cycle part of a sine curve; the generatrix 241 satisfies the functional relationship Y ═ Z × pi × sin (θ); wherein Z is a constant and has a value ranging from 0.3 to 2, in this example 0.6; theta epsilon [0 DEG, 90 DEG ], theta epsilon [3.67 DEG, 77.27 DEG ] in the present embodiment. The light emitting component 22 comprises an LED lamp bead and a light distribution lens; the outer surface of the light reflecting part 24 is plated with high-reflection substance. It should be noted that, because the sinusoidal curve is a complete sinusoidal curve, and is formed by combining 4 quarter cycles with identical shapes (only the directions are different), for the convenience of description, this embodiment only selects the shape represented by one of the quarter cycles to describe the shape of the bus, and is not related to the directivity; should not be interpreted as limiting the scope of protection of the present invention; additionally, be in the utility model discloses in order to adapt to reflection of light parts's size, after sinusoidal curve's curve interval was selected, need the whole certain multiple that enlargies according to actual need, this does not influence sinusoidal shape.

As shown in fig. 3 and 4, light emitted by the LED lamp bead is distributed by a lens and then irradiates the light reflecting member 24, and then the light is reflected to the road surface by the light reflecting member 24; in fig. 3 and 4, the light reflecting member bus bar 241; 242 is the tangent of the reflection point; 243 is emission point normal line; 244 is the reflected light; 245 is the incident ray. In this embodiment, the optical trajectory design method is to uniformly take 34 points on the generatrix of the reflective tower, then derive the functional relation Y ═ Z × pi × sin (θ) to obtain Z × pi × Cos (θ), calculate the slope of the tangent line of the reflective point, and draw the tangent line of the point. Then, a normal line is drawn through the point and perpendicular to the tangent line, and finally, the reflected light is drawn according to the incident angle being equal to the reflection angle. From the coverage of the reflected light on the ground (in the application, the straight line L represents the ground) and the distribution of the contact points of the light and the ground, the utilization efficiency of the reflected light is high, the reflected light is uniformly distributed, and the requirement of the urban road illumination design standard CJJ45-2015 on uniformity can be better met.

Fig. 1 and 2 are schematic diagrams of an illumination principle in which a reflective bus is an arc and a bus is a straight line in the prior art. In fig. 1, 2 and 3, for comparison, the incident angles of all the light rays are the same, and the optical path design method is also that 34 points are uniformly taken on the reflecting tower generatrix. Compare fig. 1, 2, 3 and know, compare in reflection of light generating line for circular arc and generating line for sharp luminous component, under equal illumination condition, it is obvious the utility model discloses a curve that sinusoidal quarter periodic part was injectd is as the solid of revolution (reflection of light part) that the generating line obtained after reflecting to the light, and effective reverberation sees all obviously better than reflection of light generating component that the generating line is circular arc and generating line for sharp to the distribution degree of consistency of contact point of light in the coverage on ground, has especially effectively alleviated light and has concentrated near the place of projecting below the lamp ball.

As a further improvement, as shown in fig. 5, a schematic diagram comparing a generatrix of the light reflecting member when the value of Z is 0.3 and the value of Z is 2 with that when the value of Z is 0.6 is shown.

In addition, it should be noted that, in the design process according to the present invention, in order to take into account (1) the optical performance: the light which is irradiated to the reflecting part by the LED light source is required to be uniformly reflected to the road surface through the reflecting part, and the utilization rate of the lamp is improved to the maximum extent (energy conservation); (2) the mold is convenient to manufacture and produce, and can be demoulded (the demoulding inclination is more than 1 degree); (3) the appearance is beautiful and the proportion is coordinated; the technical scheme is obtained through continuous tests and evidence finding of the inventor.
