Embodiment 1

[0055] A railway LED energy-saving signal lamp, including a luminous disc, a circuit module, a lens, a casing and a display system, wherein:

[0056] 109 light-emitting diode lamp beads are installed on the light-emitting disk, and the center wavelength of each light-emitting diode light bead falls within the wavelength range of each color light specified by the iron standard, and the light-emitting angle is small and the luminous intensity is high. The 109 light-emitting diodes The lamp beads are composed of 16 branches in a mixed connection, and are arranged on the luminous plate in an array to ensure that the color of the light source of the LED signal light is pure, the luminous intensity of the light source and the chromaticity coordinates meet the requirements of the iron standard. In addition, the external dimensions of the luminous disc coincide with the size of the inner glass of the signal machine, so that there is no need to change the signal mechanism during install...

Abstract

The invention relates to a signal lamp, in particular to a railway LED energy-saving signal lamp. The railway LED energy-saving signal lamp comprises a light-emitting disc, a circuit module, a lens, a shell and a display system. A plurality of LED lamp beads are installed on the light-emitting disc and form a plurality of branches in a series-parallel manner to be arranged on the light-emitting disc in an array manner. The circuit module comprises a power input circuit, a DC-DC power module, a constant-current source drive circuit, a control circuit, a maintaining current load circuit and an alarm circuit. The output end of the DC-DC power module is connected with the input end of the constant-current source drive circuit, the input end of the control circuit and the input end of the alarm circuit. The output end of the constant-current source drive circuit is connected with the input ends of the LED lamp beads and the input end of the control circuit. The output end of the control circuit is connected with the input end of the maintaining current load circuit and the input end of the alarm circuit. The railway LED energy-saving signal lamp is good in compatibility, high in light emitting strength, good in labor saving effect, low in improving difficulty and improving cost and wide in application and popularization prospect.

Description

technical field [0001] The invention relates to a signal lamp, in particular to a railway LED energy-saving signal lamp. Background technique [0002] As a new type of light source with energy saving and less maintenance, LED lights have been successfully used in railway signal display systems because of their high reliability (about 30% of the light-emitting diodes fail and will not affect the normal display of signals) and long life (The service life of LED lights is 100 times that of double-wire signal bulbs), environmental protection and energy saving (power consumption is less than 50% of that of double-wire signal bulbs), stable focus, good luminosity, and no inrush current. For the large number of railway signal lights and long lines, the advantages embodied by the LED railway display system are of great significance to the safety, reliability, energy saving and consumption reduction of the railway department. Therefore, the replacement of double-wire signal bulbs wit...
