Description
Technical Field
The invention relates to the field of low-light-position road lighting, in particular to a non-reflection light interception method for eliminating glare of a low-light-position street lamp and a lamp.
Background
The conventional low-light-level installation is generally lower than 1.4 meters. In road lighting, street lamp glare has historically been considered an important evaluation index. Glare refers to the undesirable range of light intensities within the driver's field of view, with extreme contrast of light intensity in space or time, so as to cause discomfort or visual disturbances that reduce visibility.
Recently, some lighting designers have explicitly proposed the order of requirements for conventional high-level lighting as: brightness, uniformity, glare control, and inductivity, and the order of the requirements for using low-level illumination becomes: glare control, inducibility, brightness, uniformity. Therefore, the glare control technology is a common key technology of the lighting requirements of the low-light-level street lamps.
In the prior art, a low-height flat road lighting technology exists, which adopts a metal halide light source (namely an MH light source), has the installation space of 8-11 meters and the height within 1.2 meters, and limits glare in a downward lighting mode by adopting flat beam light distribution. 90% of the direct luminous flux of the lamp is distributed within the road surface. Thereby reducing the scattered light. The lamp partially overcomes the problem of a large ineffective illumination area of a high lamp position illumination mode, but the biggest problem of the illumination mode is that a driver close to a street lamp traffic lane feels strong glare due to overhigh power density of a light source.
The LED low-level street lamps of a certain urban main road are used for lighting, the power of a single lamp is 24 watts, and the distance between the lamps is 6 meters. Although the items eliminate the glare in the front and upper sight area of the motor vehicle driver in the high-light street lamp lighting mode, the front and lower sight glare and the side glare still exist, particularly in a lane close to a street lamp, the front lighting surface of a high-brightness lamp has large influence, and the driver feels strong glare.

Because the prior art has the technical problem that the driver can easily feel strong glare by adopting the low street lamp for illumination.
In order to solve the technical problems, the invention provides a non-reflection light interception method for eliminating glare of a low-position street lamp and a lamp. In the method, the light interception plate with the preset length is arranged above the low-light-level street lamp according to the preset angle, so that the eyes of a driver are prevented from directly viewing the light emitting surface of the low-light-level street lamp, and the direct glare of the low-light-level street lamp is eliminated.

To facilitate a review of the meaning of the various parameters involved in the formulas used in the present invention, see the following table:
fig. 1 is a schematic diagram of a reflection-free light-intercepting method for eliminating glare of a low-light street lamp according to a first embodiment of the present invention. The method comprises the following steps:
the light interception plate with preset length is arranged above the low-light-level street lamp according to a preset angle so as to prevent a driver from directly seeing the light emitting surface of the low-light-level street lamp and eliminate direct glare, and all reflectors are eliminated below the low-light-level street lamp so as to prevent indirect glare caused by reflection of the reflectors.
Wherein, reference numeral 1 represents a low light level street lamp, reference numeral 2 represents a light intercepting plate, reference numeral 3 represents the ground, and reference numeral 4 represents the eyes of the driver.
Further, the length of the light interception plate is at least larger than:
y represents the minimum length of the light interception plate, D represents the light source diameter of the low-level street lamp, a represents the light source vertical angle of the low-level street lamp, and h2Indicating the height of the driver's eyes from the ground, h1The height of the bottom end of the light source of the low-position street lamp from the ground is shown, and K shows the horizontal distance between a driver and the bottom end of the light source of the low-position street lamp.
Further, the vertical angle of the light source of the low-position street lamp satisfies the following conditions:
l represents the horizontal distance between the maximum light intensity position of the low-position street lamp and the bottom end of the light source, h1The height of the bottom end of the light source of the low-position street lamp from the ground is shown, a represents the vertical angle of the light source of the low-position street lamp, and D represents the diameter of the light source of the low-position street lamp.
It should be noted that, unlike the high street lamp, the low street lamp projects light downward in a direction approximately perpendicular to the road surface, and the low street lamp projects light leftward or rightward in a direction approximately parallel to the road surface. Please refer to fig. 2, which is a schematic view of a low-light street lamp according to the present invention. Therefore, low street light glare comes from two aspects: on one hand, due to the requirement of the light projecting direction of the street lamp, the light emitting surface of the street lamp is changed from downward to side surface, and the street lamp glare is not from the vertical direction, but from the lateral light emitting surface of the front street lamp, and is horizontal glare; on the other hand, the packaged Light Emitting Diode (LED) chip emits scattered Light of approximately 120 degrees after primary Light distribution. Further focusing is required for illumination to a far distance. Therefore, the LED generally used for street lamps uses a lens to perform secondary light distribution, and the fresnel lens is one of the LEDs with better efficiency. Fig. 3 is a schematic diagram of a fresnel lens focusing principle according to the present invention. The Fresnel lens has a function of converging front light emitted by the light source and directly emitted to the Fresnel lens into nearly parallel light beams with a small beam angle, and the parabolic optical lens has a function of converging non-front light therein into nearly parallel light beams with a small beam angle. The Fresnel lens and the paraboloid lens are combined to form the Fresnel-paraboloid lens. After the light distribution is carried out by the Fresnel-paraboloid lens, the light emitted by the LED light source is converted into a circular light spot with a smaller diameter.
Theoretically, a sufficient requirement for the parabolic mirror to emit parallel light is that the light source is an infinitely small particle located at the focus of the parabolic space, and any light emitting point deviating from the particle position necessarily emits light which does not completely coincide with the main optical axis, i.e., contains non-parallel light. The non-parallel light is stray light, and the farther the focus point is, the more the stray light is. In fact, the light source with infinitely small volume does not exist, and the larger the light source volume is, the more scattered light is.
In addition, the illumination of the road surface requires a stripe-shaped light spot rather than a circular light spot having a small diameter. Therefore, a micro-structured lens with a corrugated single surface is required to be arranged in front of the Fresnel-paraboloid lens, so that the circular light spots with smaller diameters are diffused into strip-shaped light spots along the horizontal direction. However, in such a separated structure, an air space layer exists between the fresnel-parabolic lens and the micro-structured lens, and the air space layer can partially scatter the parallel light projected by the fresnel-parabolic lens, so that the light efficiency is reduced, and dust can be deposited. One effective solution is to integrate the micro-structured lens with the fresnel-parabolic lens. For example, waves are engraved on the surface of the inverted fresnel lens to form an inverted fresnel wave-parabolic lens, and a strip-shaped light spot with a clear upper cut-off line is formed by one-step molding, which can be seen from fig. 4, which is a top view and a side view of the inverted fresnel wave-parabolic lens provided by the present invention.
The inverted Fresnel ripples-parabolic lens solves the problem of stripe-shaped light spots required by road illumination, but does not solve the problem of glare. Please refer to fig. 5, which is a schematic diagram of the cause of glare according to the present invention. Theoretically, the light beams which are parallel but can not be completely parallel are scattered on the outer surface of the inverted Fresnel wave-paraboloid lens, light in the direction of a non-main optical axis forms stray light, and partial stray light directly enters eyes of a driver, so that the driver feels strong glare.
In practice, the method of distributing light by using a lens has the problem of glare which cannot be solved in practice. The key point of the solution is to enable a driver to avoid glare generated on the outer surface of the inverted Fresnel wave-paraboloid lens. Because of the wide angle of spill light scattering, motor vehicle drivers feel glare in many locations during driving.
In the embodiment of the invention, according to the mechanism of glare generation, the light interception plate with the preset length is arranged above the low-light-level street lamp according to the preset angle, so that the eyes of a driver are prevented from directly viewing the light emitting surface of the low-light-level street lamp, the direct glare of the low-light-level street lamp is eliminated, all reflectors are eliminated below the low-light-level street lamp, and the indirect glare caused by the reflection of the reflectors is avoided.
Fig. 6 is a schematic structural view of a non-glare low-position street lamp according to a second embodiment of the present invention. The lamp is applied to a non-reflection light interception method for eliminating glare of a low-position street lamp, and comprises the following steps:
a forward illumination light source 11, a backward illumination light source 12 and a lamp housing 13 without a reflector in the middle;
the forward lighting source 11 is located at the upper part of the lamp housing 13, one side of the lower part of the lamp housing 13 is an inverted V-shaped groove structure, and the backward lighting source 12 is located at the other side of the lower part of the lamp housing 13.
Further, the lengths of the two sides of the inverted V-shaped groove at the lower part of the lamp housing 13 are not equal, and the long side of the inverted V-shaped groove is connected with the side of the lamp housing 13.
Further, the length of the long side of the inverted V-shaped groove is at least greater than:
y' representsThe minimum length of the long side of the V-shaped groove, D 'represents the light source diameter of the backlight 12, a' represents the light source vertical angle of the backlight 12, and h2'denotes the height of the driver's eyes from the ground, h1'indicates the height of the bottom end of the light source of the backlight 12 from the ground, and K' indicates the horizontal distance of the driver from the bottom end of the light source of the backlight 12.
Further, the light source vertical angle of the backlight 12 satisfies:
l' represents the horizontal distance between the maximum light intensity of the backlighting source 12 and the bottom of the source, h1' denotes the height of the light source bottom end of the backlight 12 from the ground, a ' denotes the light source vertical angle of the backlight 12, and D ' denotes the light source diameter of the backlight 12.
Further, the lamp housing 13 is a rectangular lamp housing.
Further, light-proof materials are disposed on both sides of the lamp housing 13.
Further, the lamp housing 13 is provided with a connection structure to facilitate combination with a fixing device.
In particular, the installation height of the lamp requires special attention, and the installation height of the lamp is lower than the eyes of a driver. That is, the driver sits in the vehicle, and when the vehicle travels to the lamp position, the eye height of the driver should be higher than the upper edge of the forward illumination light source 11.
It should be noted that, in the driving process of a vehicle driven by a driver, the distance between the driver and the low-light-level street lamp is not simply a two-dimensional distance change relationship, but is dynamically changed in three dimensions, so that the glare of the low-light-level street lamp needs to be dynamically analyzed from the aspects of the position, the sight line and the like of the driver in the design of the low-light-level street lamp, and therefore, the efficient and reliable low-light-level street lamp is designed. Analysis shows that the glare of the low-position street lamp is divided into horizontal glare and vertical glare. Specifically, the horizontal direction glare includes horizontal direction glare from the right side of the road and horizontal direction glare from the left side of the road. The horizontal glare from the right side of the road means that, for a motor vehicle running on the right side of the road, the horizontal glare means direct light from the front of the right street lamp body sensed by a driver, and fig. 7 is a schematic diagram of the horizontal glare from the right side of the road. Similarly, the horizontal glare from the left side of the road means that, for a motor vehicle running on the left side of the road, the horizontal glare means direct light from the front of the left side street lamp body that is felt by the driver. The vertical glare refers to direct light from a front light emitting surface (vertical direction) of the front street lamp, which is felt by a driver.
further, please refer to fig. 8, which is a schematic diagram of the front view, side view and rear view glare ranges provided by the present invention, according to the definition of the unified coordinate system, the cutoff angle β of the full-cutoff street lamp is 65 degrees, the corresponding shading angle (protection angle) α is 25 degrees, the cutoff angle β of the half-cutoff street lamp is 75 degrees, the corresponding shading angle (protection angle) α is 15 degrees, specifically:
1. glare between- α and α is called forward-looking glare, in the range of 2 α, and is in the nature of incapacitating glare, with the effect of temporarily losing part of the discerning power, with the most unfavorable observation points at the- α and α angles.
The invention provides a non-reflection light interception lamp for eliminating glare of a low-lamp-position street lamp, wherein a reverse illumination light source 12 is positioned at the lower part of a lamp shell, and emitted light is opposite to the driving direction of a vehicle close to the installation position of the lamp. One side of the lower part of the lamp housing 13 is an inverted V-shaped groove structure, and the reverse illumination light source 12 is positioned on the other side of the lower part of the lamp housing 13, so that the inverted V-shaped groove achieves the effect of a light interception plate of the reverse illumination light source 12, light rays directly entering the eyes of a driver are eliminated, and forward-looking glare, namely forward-looking direct glare is eliminated effectively.
2. the glare between 90 ° - β to 90 ° + β, and 270 ° - β to 270 ° + β is side-looking glare, which ranges from 2 β in nature as discomfort glare, with the effect of loss of comfort, with the most unfavorable observation point at 90 ° -90 ° (i.e., 270 °).
According to the non-reflection light interception lamp for eliminating the glare of the low-lamp-position street lamp, the middle part of the lamp shell 13 is free of the reflector, so that when a vehicle of a driver runs to the position of the lamp, the middle part of the lamp shell 13 is free of the reflector, the forward lighting source 11 is positioned at the upper part of the lamp shell, the reverse lighting source 12 is positioned at the lower part of the lamp shell, no light directly enters the eyes of the driver, the side-view glare is avoided, and the side-view direct glare and the side-view indirect glare are eliminated.
3. the glare between 180 ° - α to 180 ° + α is a back vision glare, in the range of 2 α, in nature of incapacitating glare, with the effect of temporarily losing part of the discrimination, the most unfavorable observation points being at angles of 180 ° - α and 180 ° + α.
The invention provides a non-reflection light interception lamp for eliminating glare of a low-lamp-position street lamp, wherein a forward illumination light source 11 is positioned at the upper part of a lamp shell, and the lower edge of the forward illumination light source 11 is higher than the position of human eyes. Therefore, when the vehicle of the driver drives over the position of the lamp, when the driver looks at the rearview mirror of the vehicle, the eyes of the driver are higher than the position of the forward illumination light source 11 in the lamp, so that a light interception plate is arranged between the forward illumination light source 11 and the eyes of the driver, the driver can not see the luminous surface of the forward illumination light source 11 through the rearview mirror, and the rear-view glare is effectively eliminated, namely the rear-view direct glare is eliminated.
In the embodiment of the invention, one side of the lower part of the lamp housing 13 of the lamp is in an inverted V-shaped groove structure, and the reverse illumination light source 12 is positioned on the other side of the lower part of the lamp housing 13, so that the inverted V-shaped groove achieves the effect of a light interception plate of the reverse illumination light source 12, and forward-looking glare can be effectively eliminated. The middle part of the lamp is free from a reflector, so that no light directly irradiates eyes of a driver, and side-looking glare is avoided. The position of the forward lighting source 11 is lower than the eyes of a driver, and the driver cannot see the light emitting surface of the forward lighting source through the rearview mirror, so that the rear-view glare is effectively eliminated.
