Description
Technical Field
The invention relates to a railway signal lamp, in particular to an LED light source railway signal bulb and a special lamp holder.
Background
Railway signal lamps are important equipment for ensuring the safe operation of trains, and bulbs and lamp holders are main components thereof. At present, most of the light sources of railway signal lamps in China are 12V25W incandescent bulbs or halogen tungsten bulbs, and are heat radiation light sources which emit light after being electrified by a spiral filament.
Incandescent (or halogen tungsten) signal bulbs and lamp sockets have been known for over thirty years and have evolved into unique shapes and configurations suitable for color lamp lens sets.
As shown in fig. 1, the existing railway incandescent signal bulb mainly comprises a main filament, an auxiliary filament, a glass bulb shell and a lamp cap (P30 d/17 x 22 lamp caps) with a fixed focal plate, wherein the diameter of the lamp cap is 22mm, the lamp cap is provided with two contacts, the main filament is positioned on the axis of the lamp cap, and the height of the light center is 43mm.
As shown in figure 2, it is a lamp holder structure of incandescent bulb (or halogen tungsten bulb), it is mainly made up of insulating lamp holder block, bulb clamp plate, two contact spring pieces, binding post, lamp holder support, etc., the lamp holder clamp plate that can be inserted and pulled presses the fixed focus disc of the bulb to fix the bulb, and make two contacts of the bulb contact with two contact spring pieces on the lamp holder, supply power to the bulb, because of the restriction of lens group focal length and bulb lamp holder structure, the contact surface of sliding block and lamp holder forms 15 degrees tilt angles with horizontal direction, so that the filament can be adjusted to the focus of the lens group.
With the rapid development of semiconductor technology in recent years, an LED is used as a solid light source, and is rapidly replacing an incandescent lamp (including a halogen tungsten lamp) due to the advantages of energy saving, environmental protection, long service life, good vibration resistance and the like, so that the LED becomes a replacement choice for a railway signal bulb, a plurality of enterprises are developing LED light source signal bulbs, a plurality of LED bulbs used on the railway site are used at present, a typical structure is shown in fig. 3, and a combination of the LED light source railway signal bulb and a lamp holder is shown in fig. 4.
The above prior art has at least the following drawbacks:
the existing LED light source railway signal bulb still adopts the original incandescent bulb lamp cap, and potential safety hazards exist:
the lamp filament and glass bulb of the existing signal bulb have small mass, while the metal radiator of the LED light source railway signal bulb has large volume and 7-8 times of the mass of the incandescent bulb, and the bulb is supported by a lamp cap with the diameter of 22mm, and works in a state of 15 degrees of inclination angle with the vertical direction, so that the bulb is unsafe.
The existing LED bulb adopts the original lamp holder, and the structure is unreasonable:
the signal mechanism is arranged at two sides of the railway, and can generate strong vibration when a train passes by, and the signal mechanism comprises a bulb and a lamp holder which can bear the vibration with the frequency of 35Hz and the acceleration of 2.5 g.
The function of the lampholder is to secure the bulb and provide a reliable electrical connection for the bulb while enabling the bulb illuminant to be adjusted to the focal point of the lens. The original incandescent bulb (or halogen tungsten bulb) has small mass, vibration has no obvious influence on the bulb, the original lamp holder is adopted by the existing LED bulb, the bulb is pressed by a pressing plate, the bulb forms an inclination angle of 15 degrees with the vertical direction, and under the strong vibration condition, the LED bulb with large mass can shake severely and is easy to damage; friction is generated between two contacts of the lamp cap and the lamp holder spring plate, the contact resistance is increased, and the contact temperature rise is increased; the original lamp holder pressing plate is difficult to pull, and the difficulty in replacing the bulb is reflected on site.
The arrangement of the light emitting chips of the existing LED bulbs is not standard:
the railway signal lamp has specific requirements on luminous intensity distribution, namely, the railway signal lamp is required to have enough luminous intensity in the direction of an optical axis, and also is required to have a certain beam divergence angle, the size and arrangement position of the LED chips directly influence the luminous intensity distribution performance, and the arrangement of 1W chips used by the existing LED bulb is too dispersed, so that the luminous intensity is discontinuous, so-called 'dark areas' appear, and the signal display is not facilitated.
