Description

The LED guiding lamp

Technical field

The utility model relates to lighting device, particularly a kind of LED guiding lamp.

Background technology

For each human pilot, steering vehicle travels in road alignment and maximum speed limit variation place greatly, as: the bend of toll station, expressway ring road, viaduct, tunnel and road etc. is located, and makes the people feel special and constrains.Driver's sight line can focus on the dead ahead, and have a trend (the especially moment in the road) that the skidding that keeps left is sailed, the increase of this influence can cause the raising of the speed of a motor vehicle, and is especially dangerous for the road of two-way wagon flow, disorients, the estimation speed of a motor vehicle and distance that can not be correct, around under the Dan Tiao visual environment, cause sight line bad owing to night is dark, thus the driver need one clearly, clear and definite vision induces, induce effect good more, driver driving is safe more.

At present traditional guiding lamp exists perishablely, easily aging, easy to crack, and defective such as angular field of view is little is not suitable for high and cold, high heat, high humidity is regional.

LED(Light Emitting Diode, light emitting diode) be a kind of solid-state semiconductor devices, it can directly be converted into light to electricity, increasingly mature along with the LED technology, and led light source becomes optimal light source and removes to replace traditional light source.

Summary of the invention

The purpose of this utility model provides a kind of LED guiding lamp, and this guiding lamp has corrosion-resistant, and is high temperature resistant, and shock resistance should not be worn out, and characteristics such as angular field of view is big, is applicable to that high and cold, high heat, high humidity are regional.

The technical scheme that its technical problem that solves the utility model adopts is: design a kind of LED guiding lamp, it comprises shell, transparent window plate, LED, back shroud, it is characterized in that: back shroud is parallel octagon, two long relative edges are side, the two sides that shell links to each other with the back shroud side are trapezoidal, be symmetrically distributed in the both sides of shell, all be evenly distributed with the LED loophole that is no less than 6 on two trapezoidal sides of shell, loophole is coated with the transparent window plate outward, and LED welds on the PCB thin plate of both sides in the enclosure.

The angle of described transparent window plate and back shroud is 60 ° of angles.

Described enclosure material is a cast aluminium alloy.

The trapezoidal side of described shell, trapezoidal long limit links to each other with the side of back shroud, and trapezoidal minor face is the side of upper surface of outer cover.

Described enclosure is connected with the lead-in wire pressing plate with the middle through hole lower end screw thread that links to each other of upper surface.

Described transparent window sheet material matter is the PC material.

Respectively weld LED on the PCB thin plate of described both sides between 6-8.

Wherein PCB is exactly that (Printed circuit board PCB), briefly is exactly the thin plate that is equipped with integrated circuit and other electronic building bricks to printed circuit board (PCB); PC is the abbreviation of Merlon (Polycarbonate), and the PC material is exactly a kind of in our the said engineering plastics in fact.

The beneficial effects of the utility model are: the transparent window plate of the utility model LED guiding lamp and back shroud are 60 ° of angles, increase by 15 ° than traditional 45, and the visual angle is more extensive, judges road conditions at a distance in human pilot effectively; Shell adopts cast aluminium alloy, compares with plastic part, and it has corrosion-resistant and high-temperature resistant, and shock resistance should not be worn out, and perfect heat-dissipating uses the longevity to reach more than 10 years, is more suitable for being used in high and cold, high heat, high humidity is regional; This polygon of shell will be saved material than traditional, reduces cost; Transparent window sheet material matter is the PC material, and is heat-resisting, cold-resistant, should not ftracture; LED welds on the PCB thin plate of both sides in the enclosure, has replaced traditional light source; Enclosure is connected with the lead-in wire pressing plate with the middle through hole lower end screw thread that links to each other of upper surface can prevent effectively that power supply lead wire from causing coming off or loose contact because of long-time the use.

The specific embodiment

The structure that is not described in detail in an embodiment, its structure is identical with existing known structure.

Embodiment 1 is as Fig. 1-shown in Figure 4, the LED guiding lamp, and it comprises shell 1, transparent window plate 2, LED 5, back shroud 8, back shroud 8 is parallel octagon, and two long relative edges are side, and the two sides that shell 1 links to each other with back shroud 8 sides are trapezoidal, be symmetrically distributed in the both sides of shell 1

Back shroud 8 is by on the installing hole 7 that is bolted to shell 1 two ends, and shell 1 adopts cast aluminium alloy, compares with plastic part, and it has corrosion-resistant and high-temperature resistant, and shock resistance should not be worn out, and perfect heat-dissipating is more suitable for being used in high and cold, high heat, high humidity is regional; All be evenly distributed with 8 LED loophole 6 on two trapezoidal sides of shell 1, the loophole 6 outer transparent window plates 2 that are coated with, use the sealing of 519 glue with the junction of shell 1 around the transparent window plate 2, transparent window plate 2 is 60 ° of angles with the angle of back shroud 8, increase by 15 ° than traditional 45, the visual angle is more extensive, judges road conditions at a distance in human pilot effectively; Transparent window plate 2 materials are the PC material, and are heat-resisting, cold-resistant, not easy to crack; PCB thin plate 3 places the both sides in the shell 1, respectively is welded with eight LED 5 on the PCB thin plate 3 of both sides, totally ten six, inserts the low-voltage of direct current 24V and powers, to not injury of human body; PCB thin plate 3 uses with the sealing of 705 glue with shell 1 junction, is isolated from the outside, and is welded with backward dioded on the PCB thin plate 3, plays protection LED 5 effects when electric current and voltage suddenlys change; Shell 1 inside is connected with lead-in wire pressing plate 4 with the middle through hole 9 lower end screw threads that link to each other of upper surface can prevent effectively that power supply lead wire from causing coming off or loose contact because of long-time the use; The inner different sealing glue that adopts of shell 1 is sealed to form through twice, good seal performance, with aluminum alloy casing easily heat radiation combine, effectively solved the heat dissipation problem of LED, improve LED service life.
