Description
Technical field
The present invention relates to a kind of railway signal lamp, more particularly to a kind of LED light source railway signal bulb and special lamp holder.
Background technology
Railway signal lamp is the visual plant for ensureing safe train operation, and bulb and lamp socket are its critical pieces.At present I
Most of light source of state's railway signal lamp is 12V25W incandescent lamp bulbs or halogen tungsten bulb, is the heat lighted after coiled-coil filament is powered
Radiating light source.
Incandescent (or halogen tungsten) signal lamp and existing more than the 30 years history of lamp socket, have gradually formed and have been suitable for colored lights lens group
Unique shape and structure.
As shown in figure 1, existing railway white heat signal lamp be mainly by major and minor two Double-spiral filaments, glass cell-shell,
The lamp holder (P30d/17*22 lamp holders) that a diameter of 22mm has prefocus plate is constituted, and lamp holder has two contacts, and main filament is located at lamp holder
Axis on, light center highly be 43mm.
As shown in Fig. 2 being the holder structure figure of incandescent lamp bulb (or halogen tungsten bulb), it is mainly by insulating lamp holder block, lamp
The composition such as bubble pressing plate, two contact shell fragments, binding post, light holder supports, the lamp socket pressing plate that can be plugged and unplugged pushes down focusing for bulb
Disk fixes bulb, and two contacts of bulb is in contact with two contact shell fragments on lamp socket, to bulb powered, due to saturating
The limitation of microscope group focal length and contact holder structure, sliding shoe is in 15 degree of inclinations angle with horizontal direction with lamp holder contact surface, so as to lamp
Silk can be transferred in the focus of lens group.
Developed rapidly recently as semiconductor technology, LED as solid light source, because of its energy-conserving and environment-protective, long-life, antivibration
The superiority such as performance is good substitutes rapidly incandescent lamp (including halogen tungsten lamp), the alternative as railway signal bulb, at present
There are many kinds, typical structure such as Fig. 3 institutes in many enterprises in exploitation LED light source signal lamp, the LED bulb that Railway Site is used
Show, LED light source railway signal bulb is shown in Fig. 4 with lamp holder combination.
Above-mentioned prior art at least has the following disadvantages：
Existing LED light source railway signal bulb still uses original incandescent lamp bulb lamp holder, there is potential safety hazard：
The filament and glass bulb quality of existing signal lamp are small, and the metal heat sink volume of LED light source railway signal bulb
Greatly, quality is 7~8 times of incandescent lamp bulb, is all supported by the lamp holder of diameter 22mm, and bulb is in 15 degree of inclination angle shapes with vertical direction
Worked under state, be unsafe.
Existing LED bulb uses original lamp socket, unreasonable structure：
Signaling gear is arranged on railway both sides, can produce strong vibration when train passes through, signaling gear include bulb and
Lamp socket should be able to bear the vibration that frequency is 35Hz acceleration 2.5g.
The function of lamp socket is to fix bulb and for bulb provides reliable electrical connection, while can adjust bulb illuminator
Onto lens focus.Original incandescent lamp bulb (or halogen tungsten bulb) quality is small, and vibration is influenceed not substantially on it, and existing LED bulb is adopted
Original lamp socket is used, bulb is pushed down with pressing plate, bulb is in 15 degree of inclination angles with vertical direction, and under the conditions of judder, quality is very big
LED bulb can be produced acutely rocks, and is easily damaged；Two contacts that lamp holder is contacted with lamp socket shell fragment can produce friction, contact electricity
Resistive is big, causes contact temperature rise to increase；Original lamp socket pressing plate pulls difficult, scene reflection replacing bulb difficulty.
Existing LED bulb luminescence chip arrangement is lack of standardization：
Particular requirement is distributed with to luminous intensity for railway signal lamp, that is, require there are enough luminous intensities in optical axis direction,
Require there is certain light beam divergence angle again, the size of LED chip, arrangement position directly affect luminous intensity distribution performance, existing LED
The 1W arrangements of chips that bulb is used excessively is disperseed, and causes luminous intensity discontinuous, is occurred so-called " dark space ", is unfavorable for that signal shows
Show.
The content of the invention
It is an object of the invention to provide a kind of luminous intensity it is continuous, it is fixed it is reliable, change the convenient LED light source of lamp operation
Railway signal bulb and special lamp holder.
The purpose of the present invention is achieved through the following technical solutions：
LED light source railway signal bulb of the invention, including cylindrical light foam, the front portion of the cylindrical light foam set
The draw-in groove of fixed bulb, front end are provided with LED chip and translucent cover, rear end were provided with the end of a thread and connect to have fin, rear portion to be provided with
Coil, is provided with the projection for differentiating LED chip color at the draw-in groove.
The special lamp holder of LED light source railway signal bulb of the invention, including the semicircular collar A that side is hinged
With collar B, the draw-in groove of the LED light source railway signal bulb is fixed in the annular chamber that the collar A and collar B are surrounded.
As seen from the above technical solution provided by the invention, LED light source railway signal provided in an embodiment of the present invention
Bulb and special lamp holder.Bulb does not have lamp holder and horizontal positioned, and bulb is not with shell fragment with the electrical connection of lamp socket but uses wiring
Terminal, bulb luminous intensity is continuous, shown beneficial to signal；Lamp socket is prevented from bulb and rocks, and adapts to the building ring of judder
Border, changes lamp operation conveniently, safe and reliable.
