Abstract
A railway LED signal lamp comprises a plurality of high-power light emitting diodes, a metal substrate, a radiator, a lampshade and a lamp socket, wherein the metal substrate includes a main light source area and an accessory light source area. The high-power light emitting diodes are densely arranged in the main light source area and the accessory light source area, a convex lens covers the outsides of the main light source area and the accessory light source area, the metal substrate is arranged on a support, and the main light source area and the accessory light source area are respectively connected with a connecting terminal connected with a control circuit. Light sources are centralized at a point by the aid of the convex lens to form a luminous point, so that the defect that a divergence angle is larger when a lamp of a traffic signal machine is turned on is overcome. As the signal lamp is provided with a main light source and an accessory light source, when the main light source has the failure of blackout, the accessory light source can continue to illuminate, and correct and reliable operation of a signal lighting circuit is ensured.
Description
Technical field
The utility model relates to the LED signal lamp, in particular for the LED signal lamp of railway signal.
Background technology
The signal bulb is the special-purpose assorted product of railway signal, is installed in signaling at stations mechanism and the wayside signaling mechanism, to train various signals is provided according to different instructions.The big requirement of signal bulb consumption is high, uses certain hour to change.Development along with railway transportation; The train current density is increasing, and is also increasingly high to the requirement of signal bulb, and signal has begun progressively to use the LED LED source in the road at present; The mode of using has two kinds; A kind of mode is luminous disc type, and by the disc type light emitting source that tens light-emitting diodes are formed, another kind is the point type light emitting source; Disperse to be installed in the circular radiator that end face diameter is 50 millimeter by several large-power light-emitting diodes, add the bulb-type light emitting source that the common plastics cover is formed.The subject matter that existing point type light emitting source exists, the light that light source sends are several points and can not concentrating on a bit, and the angle of loosing when making the bright lamp of signal is bigger than normal, exceeds Ministry of Railways's standard range requirement, can not satisfy on-the-spot the use.
The utility model content
The purpose of the utility model is to solve that light emitting source can not concentrate on a bit in the prior art, and the angle problem bigger than normal of loosing when causing the bright lamp of signal provides a kind of light source that makes to concentrate on the railway LED signal lamp that has king light, secondary lamp two-way light source of a bit.
The technical scheme of the utility model is: a kind of railway LED signal lamp; Comprise light-emitting diode, metal substrate, radiator, lampshade and lamp socket; Said metal substrate is divided into key light source region and secondary light source region, and dense arrangement has many large-power light-emitting diodes in key light source region and secondary light source region, and the outside is covered with convex lens; Metal substrate is arranged on the support, and key light source region and secondary light source region are connected to connection terminal respectively and link to each other with control circuit.
Preferably, said metal substrate is the circular substrate of 12 millimeters of diameters.
Preferably, said metal substrate is a copper base.
The beneficial effect of the utility model is: a kind of railway LED of the utility model signal lamp, use protruding visor that light source is concentrated on a bit to form a luminous point, the angle defective bigger than normal of loosing when solving the bright lamp of signal; And be provided with major and minor two-way light source, when main light source was turned off the light fault, secondary light source still can continue to light, and guarantees the correct reliable operation of signal light circuit.

Fig. 2 is the point type light emitting source lateral plan of the railway LED signal lamp of the utility model;
Fig. 3 is the structural representation of the railway LED signal lamp of the utility model;
Fig. 4 is the structural representation of the railway LED signal lamp of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.A kind of railway LED signal lamp comprises light-emitting diode 1, metal substrate 2, radiator 6, lampshade 5 and lamp socket 7, and said metal substrate 2 is divided into key light source region 21 and secondary light source region 22; It is in 12 millimeters the round metal substrate 2 that many particles large-power light-emitting diodes is arranged in diameter closely, and is evenly distributed in key light source region 21 and the secondary light source region 22, and the metal substrate outside is covered with a protruding visor 3; Protruding visor concentrates on light source and a bit forms a luminous point; The angle defective bigger than normal of loosing when solving the bright lamp of signal, key light source region 21 and secondary light source region 22 are respectively equipped with connection terminal 23 and link to each other with control circuit, and metal substrate is arranged on the support 4; Form the point type light emitting source thus; This point type light emitting source front is provided with lampshade 5, and the back side connects radiator 6, is connected with lamp socket 7 again.Said metal substrate can be a copper base.
When signal lighting circuit was open, signal lighting power source was added to the input end of the power subsystem unit of lighting a lamp (abbreviation lighting unit) voltage transformer of LED point type light emitting source through cable, behind secondary bridge rectifier; By chip controls two-way constant current source output Constant Direct Current electric current, make LED point type light emitting source major-minor light source igniting, when main light source is turned off the light fault; Secondary light source continues to light, and lighting unit is seen alerting signal off, when the major-minor light source is turned off the light fault simultaneously; Filament relay falls in the Machine Room; Warning circuit sends alerting signal, and when signal lighting power source was lower than 120V, the lighting unit threshold circuit was not worked; LED point type light source is not lighted, and guarantees the correct reliable operation of signal light circuit.
Adopt the signaling gear of point type LED light emitting source, in a plurality of stations of railway He in the wayside signaling lamp circuit, use, each item index all satisfies the requirement of iron mark, through long-term use fault does not take place, and has guaranteed traffic safety.
