Description

LED light distribution emergent structure and light-emitting spike with same
Technical Field
The invention relates to the field of light emitting devices, in particular to an LED light distribution emergent structure and a light emitting spike with the structure.
Technical Field
The lighting fixture with lighting inducing or auxiliary lighting function includes underground lamp, lighting spike, solar floor lamp, contour mark, etc. and is mainly served by motor vehicle driver or pedestrian. As a light-emitting device mainly applied to public places, compared with a common light-emitting device, the light-emitting device not only needs to consider the light-emitting performance, but also needs to meet structural strength requirements such as compression resistance, impact resistance and the like and waterproof requirements, and also needs to meet some safety standards, so that the requirements on the comprehensive performance of the light-emitting devices are more rigorous. Among them, the most widely used light emitting spike is taken as a representative.
The luminous spike is also called a luminous raised road sign, is mainly installed on a road surface, has a luminous function, mainly plays a role in visual induction or prompting for motor vehicle drivers and pedestrians, and can also serve as a road surface auxiliary lighting fixture.
The existing luminous spike takes a convex luminous spike as a main part and is mainly installed on a road surface, and the highest position of the spike is not 25mm higher than the road surface; when the underground luminous spike is used, the main body of the underground luminous spike is embedded in the road surface, the top of the underground luminous spike is flush with the road surface or slightly protrudes out of the road surface, generally the height of the top of the underground luminous spike is not more than 10mm, and preferably the height of the top of the main body of the underground luminous spike is controlled to be less than 8mm, the protruding part of the road surface is better, otherwise, the vehicle bumps too much. Moreover, the luminous spike must have enough structural strength, such as resistance to rolling by over 10 tons, or be easily broken.
The main light-emitting structures of the existing spikes are mainly classified into two categories:
the luminous structure of one of them kind of luminous spike adopts and to perforate the even shot at spike protection casing lateral part more, it is luminous that perforation lamp pearl roughly directly sees through the level according to former direction and gives out light, luminous intensity in the level direction accounts for comparatively greatly, long-range luminous is good, good to the driving, but because the luminous intensity distribution of LED is close 180 lambert's body, the luminous radial luminous light of its LED is sheltered from by the casing of perforation portion, therefore the light energy utilization is rateed lowly, the light-emitting area diminishes, luminous effect to short range pedestrian is poor, can not accomplish people's car well. Most of the raised spikes adopt such a structure, and the above-described perforated flat light exit structure is not suitable for the buried spike due to the limitation of the height of the ridge.
In order to ensure the visible distance and the long-distance luminous effect of the convex spike and ensure the compression resistance and impact resistance of the spike, a certain top shell thickness is needed and the spike protrudes out of the road surface to a higher degree, so that the vehicle jolts due to the impact of wheels, the collision of pedestrians or non-motor vehicle drivers is easily caused, traffic accidents are induced, snow shoveling is not prevented, the process is complicated, and water is easily fed.
The light emitting structure of the other type of light emitting spike adopts an inverted V-shaped LED light distribution emergent structure, namely, the top of a light outlet groove is inverted V-shaped, a straw hat lamp bead is vertically upwards or obliquely upwards arranged in the light outlet groove, and emitted light emits upwards and laterally through refraction, reflection and transmission. Most earth-boring spikes adopt this type of construction. It mainly has the following major drawbacks:
1. the lamp beads are vertically upward or obliquely upward, the light intensity distribution is unreasonable, a large part of light energy penetrates through the top part of the light outlet groove and is emitted upwards, the ratio of the light intensity of the light emitted in the upward direction is large, the utilization rate of the light energy in the horizontal direction is low, the visible distance of long-distance light emission is short, the identification degree is low, light interference and glare are easily caused to pedestrians and non-motor vehicle drivers due to short-range light emission within a certain angle, and traffic accidents are easily caused. The lighting condition on high-grade roads and urban main roads is improved to be between 20 and 30Lux due to the revised road lighting standard. In addition, the development of lighting technology and the brightness of the car lamp are also improved, so that the limitations of low horizontal-direction light-emitting brightness and poor identification degree of the existing light-emitting spike can not meet the current development situation of a new road.
2. The top part of the inverted V-shaped light-emitting groove has thinner wall thickness, smaller structural strength and insufficient compression resistance and impact resistance, and the shell is easy to damage;
3. the inverted V-shaped light-emitting groove is not beneficial to an injection molding process, the inverted V-shaped light-emitting groove is large in stress and easy to crack, the installation angle and the positioning requirement of the straw hat lamp bead to be debugged are high in order to achieve a good remote light-emitting effect, inconvenience is brought to assembly, and the product consistency is poor.
In summary, the existing light emitting devices represented by the light emitting spikes all have unreasonable light distribution and emitting structures of LEDs, so that the light field distribution of the light emitting and emitting portions of the spikes is unreasonable, the reasonable distribution of light intensity ratio is not facilitated, the utilization rate of horizontal light energy is low, the remote light emitting effect is poor, short-range light emission easily causes light interference, people and vehicles cannot be well considered, the main defects of flattening and intensification of the devices, poor structural strength, no compression resistance and impact resistance, complex manufacturing and installation and the like are not overcome in the size limitation range of the existing traffic specifications, and the new development requirements are not met, so that the problem to be solved urgently in the industry is solved.

1. by utilizing the light emitting characteristic of an LED device, the LED light distribution emergent structure is innovatively designed through light emitting matching, mutual matching of optical design and optical structure parameters of a light path and combination with a specific physical structure, particularly, the optical parameters such as the light incident surface, the light emergent surface, the angle, the height, the width, the side wall thickness between the light incident surface and the light emergent surface are matched with the physical structure, the purpose of optimizing distribution of an emergent light space light field (intensity) is achieved through specific parameter matching, the expected purpose of the required design is achieved, the process forming and the production implementation are facilitated, light emitted by an LED luminous body is firstly condensed by a condensing lens, the light intensity occupation ratio of the LED in the horizontal direction is high, then the main emergent light of the LED is deflected or horizontally emitted after being upwardly displaced by delta H (theta 1 is more than theta 2) through secondary refraction of the inner wall and the outer wall according to the refraction theorem n1sin alpha 1= n2sin alpha 2, and when theta 3 is more than 0, the main emergent light of the LED is, and exit along the horizontal direction; theta 1= theta 2, and during theta 3=0, the main emergent light of LED takes place displacement Δ H upwards after transparent casing refraction, and along the horizontal direction outgoing), thereby can improve the design allowance (Δ H) that the spike structure can make the shell structure of spike compacter, the height that exposes the road surface when can reducing the spike installation, reduce the sense of jolting to the vehicle and the colliding with to pedestrian and non-motor driver, also can guarantee under the prerequisite of spike visible distance, in the size restriction scope that satisfies the traffic standard, can be through the thickness of increase topshell, further increase the structural strength and the resistance to compression shock resistance of spike.

According to the refraction theorem n1sin alpha 1= n2sin alpha 2, the light refractive index n of the transparent material of the transparent shell, the inclination angle one (theta 1) of the light inlet surface (1 b), the inclination angle two (theta 2) of the light outlet surface (1 a), the elevation angle (theta 3) of the main light beam in the normal direction after the LED luminous body (2) is condensed by the condenser lens, the thickness (H1) from the highest point of the top of the accommodating groove (1 c) to the top surface of the transparent shell (1), the height (H2) of the light outlet surface (1 a), the height (H3) of the light inlet surface (1 b), and the average width (W) between the light inlet surface (1 b) and the light outlet surface (1 a) meet the condition that most of light energy of the LED luminous body can horizontally emit (under the illumination condition of 20LUX to 30LUX, a user can still see a lamp bead with the diameter which is larger than or equal to the diameter of H2 and is still in, The luminous spot with smaller length diameter or approximate to 1, plump and larger area has very high identification degree, and the conventional light emergent structure which does not meet the light emergent condition of the invention can only see the defective luminous spot with smaller area, so that the light emergent efficiency of the spike in the horizontal direction is high (namely, the light emitted by the spike is mainly concentrated in the horizontal direction), thereby increasing the luminous visible distance as much as possible and being beneficial to providing luminous induction and indication for a motor vehicle driver; the proportion of horizontal emergence and upward emergence can be distributed through the condensing lens, so that the light energy utilization rate of the horizontal emergence and the upward emergence is higher, and the pertinence is stronger.
3. The light-emitting groove top is arch (the cross section is similar to the shape of an inverted U), not only does benefit to the injection molding process of transparent shell, but also makes the LED light distribution emergent structure of the light-emitting spike higher in structural strength, stronger in anti-pressure and anti-impact capacity, simpler in installation of the LED luminous body and better in product consistency.
