Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred reality described herein Execute example be merely to illustrate and explain the present invention, be not intended to limit the present invention.
As depicted in figs. 1 and 2, one railway signal lamp of the present invention, including shell 1, mounting bracket 2, LED lamp panel 3, light Dissipating components and parts and lens 7, described mounting bracket 2 is fixed on shell 1 by locating dowel 8;Described LED lamp panel 3, divergence of beam Components and parts and lens 7 are linked in sequence and are fixed in mounting bracket 2;It is provided with in the middle of described LED lamp panel 3 and divergence of beam components and parts Pad 9;It is provided with locating dowel 8 in the middle of described divergence of beam components and parts and lens 7;It is provided with power supply 10 in described shell 1 and drives 11; Described divergence of beam components and parts, lens 7 and locating dowel 8 are fixed by screw 12;Described lens 7 are honeycomb fashion lens;Described LED Lamp plate 3 is provided with LED lamp bead;Described divergence of beam components and parts are diaphragm 4;The material of described diaphragm 4 is aluminium alloy.
Its housing 1 is the circuit board in order to protect inside, it is simple to install fixing all parts;Power supply 10 and driving 11 are In order to power to LED;Mounting bracket 2 is to coordinate with shell 1, and power supply 10 and driving 11 are fixed, protected;Pad 9 In order to ensure LED lamp panel 3 and the spacing of divergence of beam components and parts;The circular hole corresponding with LED array it has been covered with above diaphragm 4, Its shape is circular aperture, and thickness is thin, and its effect is just can only to be gone out by this circular hole by blocking the light sent by LED Penetrate, thus the light-emitting area of LED is converted to the circular luminous face of fixed size;Preferably diaphragm 4 material is aluminium alloy, surface sun Pole oxidation black processes, and its surface reflectivity is less than 1%;Lens 7 are lens 7 array elements matched with LED array, Its position divergence of beam to be ensured components and parts are positioned near the focal position on the left of it, and its effect is divergence of beam components and parts The light penetrated is assembled, and projects the circular light spot of fixed angle.
As it is shown on figure 3, described divergence of beam components and parts are reflector 5;The material of described reflector 5 is die casting aluminium.Reflection Being covered with hollow reflector 5 array corresponding with LED array above device 5, the inside that its single shape is cylindrical is coated with height The material of reflectance, such as chromium plating process;Its reflectance is higher than 85%;Preferably reflector base material uses die casting aluminium, surface electricity Plating;Its effect is ability outgoing after the light sent by LED can only be reflected by this reflector, thus by the luminescence of LED Face is converted to the circular luminous face of fixed size.
As shown in Figure 4, described divergence of beam components and parts are light pipe assembly 6;The material of described light pipe assembly 6 is BK7 Glass.Being covered with the cylindrical light pipe array corresponding with LED array above light pipe assembly 6, its shape is cylinder, for tool There is the material of high transmission rate;Preferably material is BK7 glass;Its refractive index is 1.52;Its effect is that the light sent by LED is led Enter this light-guiding pillar, and ability outgoing after side surface reflects, thus the circle that the light-emitting area of LED is converted to fixed size is sent out Bright finish.
One railway signal lamp of the present invention, have that stable performance, service behaviour be safe and reliable, power and energy saving, service life The advantage such as long, easy to maintenance, the light path system of the present invention is to use diaphragm 4, reflector 5 and the optics of light pipe assembly 6, Different LED light-emitting area is converted to the same light-emitting area, thus ensure that signal lights projects the hot spot, highly of circle Consistent beam angle.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to aforementioned reality Executing example to be described in detail the present invention, for a person skilled in the art, it still can be to aforementioned each enforcement Technical scheme described in example is modified, or wherein portion of techniques feature is carried out equivalent.All essences in the present invention Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
