Abstract

The invention discloses a signal lamp with LEDs and light guide fibers and relates to the technical field of traffic signal lamps. The signal lamp overcomes technological defects of high cost and power consumption, short service life, poor waterproof effect, unobvious warning effect and the like for conventional pedestrian crossing signal lamps, and comprises a substrate. A red dot matrix zone, a green static dot matrix zone, a green first dynamic dot matrix zone and a green second dynamic dot matrix zone are arranged on the substrate. The signal lamp is characterized in that a red LED, a green static LED, a green first dynamic LED and a green second dynamic LED which respectively correspond to the red dot matrix zone, the green static dot matrix zone, the green first dynamic dot matrix zone and the green second dynamic dot matrix zone are arranged on the back of the substrate, and light transmitted by each LED is conducted to the corresponding dot matrix zone via the corresponding light guide fibers, and each LED is connected with more than two light guide fibers. The signal lamp with the LEDs and the light guide fibers has the advantages that the signal lamp effectively draws attention of pedestrians crossing a road, a warning effect is enhanced, limits on heat dissipation are eliminated, cost is saved greatly due to the fact that a static red little person pattern or a dynamic green little person pattern is arranged in one signal lamp, and the service life is long.

Description

The fiber-optic signal lamp of a kind of LED

Technical field

The present invention relates to the traffic lights technical field, be specifically related to the light-source structure improvement aspect of crossing signal.

Background technology

Pedestrian crosswalk signal lamp is that the pedestrian who goes across the road provides the safety instruction signal; The tradition pedestrian crosswalk signal lamp generally all is to adopt LED that red light source or green light source directly are provided; Constitute the red person of low position's figure that stands still and need a large amount of red LED and green LED with green dynamic person of low position's figure of walking; And, in a signal lamp, can't put into the red LED and the green LED that constitute red person of low position and green walking person of low position simultaneously, thereby need small cup separate signal lamp mutually.In addition, because the employed LED quantity of traditional crossing signal is many, radiating effect is poor, thereby directly causes the serviceable life of LED short; Also have because pedestrian crosswalk signal lamp need be considered in the effect that does not influence conspicuousness water proofing property simultaneously, the water proofing property complex structure, waterproof effect is poor; Also have, the LED that constitutes red person of low position and green walking person of low position in traditional crossing signal is big at interval, looks it all is pointolite independently, the caution DeGrain.

Summary of the invention

In sum, it is high to the objective of the invention is to solve traditional crossing signal cost, and power consumption is big, and serviceable life is short, and waterproof effect is poor, technical deficiencies such as caution DeGrain, and the fiber-optic signal lamp of a kind of LED that proposes.

For solving technical matters proposed by the invention; The technical scheme that adopts is: the fiber-optic signal lamp of a kind of LED; Include a substrate; On substrate, be provided with red dot matrix area, green static dot matrix area, the green first dynamic dot matrix area and the green second dynamic dot matrix area, it is characterized in that: the back side of described substrate is provided with respectively and red dot matrix area, green static dot matrix area, the green first dynamic dot matrix area, the corresponding red LED of the green second dynamic dot matrix area, green static LED, green first dynamic LED, green second dynamic LED; Described each LED conducts to its light that sends in each self-corresponding dot matrix area through optical fibers; Wherein each LED is connected with the optical fibers more than two.

Further qualification as to technical scheme of the present invention also includes:

Described each fiber-optic bright dipping end is embedded in the substrate, and the exiting surface and the substrate of bright dipping end are in the same plane.

Described substrate surface is an ater.

Described optical fibers diameter is 0.5mm.

Described red dot matrix area is connected with 150～200 optical fiberses, by 3～5 red LED red light source is provided; The static dot matrix area of described green is connected with 50～70 optical fiberses, by 1～2 green static LED green light source is provided; The described green first dynamic dot matrix area is connected with 50～70 optical fiberses, by 1～2 green first dynamic LED green light source is provided; The described green second dynamic dot matrix area is connected with 50～70 optical fiberses, by 1～2 green second dynamic LED green light source is provided.

Again a step, described red dot matrix area is connected with 180 optical fiberses, by 3 red LED red light source is provided; The static dot matrix area of described green is connected with 60 optical fiberses, by 1 green static LED green light source is provided; The described green first dynamic dot matrix area is connected with 60 optical fiberses, by 1 green first dynamic LED green light source is provided; The described green second dynamic dot matrix area is connected with 60 optical fiberses, by 1 green second dynamic LED green light source is provided.

Beneficial effect of the present invention is: the present invention adopts many optical fiberses to be transmitted to the light that a LED sends on the substrate dispersedly; When watching on the road opposite or in the middle of the road; Form red person of low position's figure or green dynamically person of low position's figure that area source constitutes; Promote the pedestrian's notice of going across the road, increased the caution effect; Since with traditional pedestrian crosswalk signal lamp savings in comparison a large amount of LED, employing be that optical fibers carries out static red person of low position or dynamic green person of low position's graphic presentation, with respect to the pixel that increase to constitute dot matrix; Broken away from the restriction of heat radiation between pixel, improved density, can also static red person of low position or dynamic green person of low position's figure be located in the signal lamp simultaneously; A large amount of providing cost savings, LED quantity is few, good heat dissipation effect; Long service life, waterproof construction only need that only several LED are carried out waterproof and get final product, and optical fibers need not to carry out waterproof; Waterproof construction requires low, and waterproof construction is simple.
