Description

LED light emergent structure and luminous spike with same

Technical Field

The invention relates to the field of light emitting devices, in particular to an LED light emergent structure and a light emitting spike with the structure.

Technical Field

The luminous spike is also called luminous raised road sign, is mainly installed on the road surface, has a luminous function, mainly plays a role in visual induction or prompt 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 generally higher than the road surface by more than 20 mm; there are also buried light emitting spikes, which are used with their main body buried in the road surface and their tops flush with the road surface or slightly raised from the bottom surface.

The main light-emitting structures of the existing spikes are mainly classified into two categories:

the light-emitting structure of one type of light-emitting spike mostly adopts the mode of perforating on the side portion and flat-shooting, the perforated lamp beads directly penetrate out of the light-reflecting sheet to horizontally emit light approximately according to the original direction, and the light intensity of the light emitted in the horizontal direction is larger. Because the luminous intensity distribution of the LED is close to a 180-degree Lambert body, the radial luminous intensity part is covered to cause light energy loss, the light energy utilization rate is low, and the power supply pressure of the solar system can be increased. 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 emitting structure, namely, the top of a light emitting groove is inverted V-shaped, a straw hat lamp bead is vertically upwards or obliquely upwards arranged in the light emitting groove, and emitted light emits light 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 light intensity distribution of the lamp beads is unreasonable when the lamp beads are vertically upward or obliquely upward, a large part of light energy is emitted upwards through the top part of the light outlet groove, the ratio of the light intensity of the light emitted in the upward direction is large, the long-distance light emitting visual distance is short, the effect is poor, the light energy utilization rate is low, short-distance light emitting easily causes light interference and glare to pedestrians and non-motor vehicle drivers, and traffic accidents are easily caused.

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 conclusion, the existing light-emitting spike has the main defects that the light-emitting structure of an LED is unreasonable, the light field distribution of the light-emitting part of the spike is unreasonable, the distribution of light intensity ratio is not facilitated, the light energy utilization rate is low, the remote light-emitting effect is poor, the short-range light emission easily causes light interference, the height of the spike protruding out of the road surface is not easily reduced within the size limit range of the existing traffic specification, the structural strength is poor, the pressure resistance and the impact resistance are not realized, the manufacturing and the installation are complicated, the diversified requirements of the road cannot be met, and the popularization and the use of the light-emitting spike are seriously hindered.
