Flush identification signal lamp and flush identification signal lamp device
The present invention relates to flush identification signal lamp and flush identification signal lamp device.
Inventors of the present invention invented adopt the miniaturization marker lamp with lamp portion imbed marker lamp and flush identification signal lamp device, and it as Japanese application for a patent for invention 1996-262709 number Japanese application for a patent for invention is proposed.Figure 22 is the optical axis phantom of this flush identification signal lamp device of formerly inventing.Figure 23 then is the cutaway view of this marker lamp with lamp portion.
In the drawings, the 101st, lamp body, the 102nd, prism, the 103rd, marker lamp lamp portion, the 104th, pedestal.
Lamp body 101 has leaded light groove 101a that is arranged on upper wall surface and the inner space 101b that is communicated with leaded light groove 101a.And lamp body 101 constitutes by top lamp body 101c and by the bottom lamp body 101d of its covering.
Be arranged between the leaded light groove 101a and inner space 101b of lamp body 101 prism 10 watertights, light path is restricted to and the road surface between form low-angle state.
Marker lamp with lamp portion 103 as shown in figure 23, be in advance in the inside of reflector 103a, under the state on the roughly focus of the reflecting surface 103a1 that being centered close to of filament 103b1 is made of the single paraboloid of revolution with the fixing bulb 103b and form an integral body of lamp holder adhesive 103c.The integrally formed tube 103a2 of portion in the top of reflector 103a inserts the sealing 103b1 of bulb 103b in the 103a2 of this, and injects lamp holder adhesive 103c in the gap between them and fix.
Marker lamp is configured as on the top of its reflector 103a openend one side with lamp portion 103 and forms the shape of scabbling the 103a3 of portion.And as shown in figure 22, in the lamp body 101 of flush identification signal lamp, reflector 103a is positioned at the position that is not higher than prism 102, so that the reverberation of reflector 103a entrance prism 102 as much as possible.
In addition, in Figure 22, G represents to bury underground the road surface of marker lamp.
And flush identification signal lamp is that state that the upper wall surface with its lamp body 101 exposes is imbedded road surface G and used.The position relation that marker lamp remains fixed in regulation in advance with the reflector 103a and the bulb 103b of lamp portion 103, so regulating, the optics of flush identification signal lamp carries out easily, owing to forming, the top at reflector 103a scabbles the 103a3 of portion simultaneously, so can shorten the height dimension of flush identification signal lamp.
Yet, require the further slimming of flush identification signal lamp now, wish to occur adapting to marker lamp lamp portion, flush identification signal lamp and the flush identification signal lamp device of this requirement.
In addition, the flush identification signal lamp that the airport is used must satisfy less elevation coverage and about keep the light distribution characteristic of regulation luminous intensity in the bigger horizontal angular range, and require to satisfy the light distribution characteristic of this regulation with lamp portion with the marker lamp of power consumption minimum, and this easy absolutely not act.
The object of the present invention is to provide and a kind of marker lamp is improved, can be realized the further slimming of flush identification signal lamp, simultaneously obtains the flush identification signal lamp and the flush identification signal lamp device of required light distribution characteristic easily with the reflector of lamp portion.
Technical solution of the present invention 1 is provided with lamp body, the restriction light path has leaded light groove of being located at upper wall surface and being tilted to and the inner space that is communicated with the leaded light groove with prism and marker lamp lamp portion, described lamp body; Described restriction light path thickly is arranged between the leaded light groove and inner space of lamp body with prism liquid; Described marker lamp with lamp portion by have bulb shield, be encapsulated in the bulb of filament in the bulb shield and the foot that is connected with filament and be oppositely arranged with this bulb and openend and prism is relative, the reflector that scabbles simultaneously constitutes the top and the bottom of openend one side and optical axis almost parallel optically.
The definition and the art-recognized meanings of used term are as described below in the present invention and following each invention.Flush identification signal lamp of the present invention be applicable to the airport c-l lights, slide street lamp, stop line lamp etc., and the crosspoint identification light of highway etc.
About bulb, from the requirement of small-sized and big light output, the most handy based on halogen bulb, but the bulb that is filled with krypton gas or xenon also can satisfy the requirement that more small-sized and big light is exported, and the not small-sized and big light of special requirement output of the occasion that has, so also permission with other bulb.Having a kind of in the based on halogen bulb is to form infrared reflection film on the bulb shield surface, because of its luminous efficiency height, so this structure is particularly suitable for the present invention.
About reflector, preferably at the high reflectance coating of the inner face of matrix coating reflectivity, if but matrix itself is to be made of high material of reflectivity such as raffinal etc., then needn't apply reflectance coating in addition, and in addition, glass or metal are applicable to makes matrix.
On reflector, the reflector center line on the geometry meaning that the optical axis that general existence and optical effect are determined has nothing to do.The present invention is referred to as the central shaft of reflector.
Flush identification signal lamp must be used the less elevation angle irradiation light of phase road pavement, and is difficult in the inner phase road pavement of lamp body is set lamp portion with smaller angle optical axis.For this reason, clamp prism, make from the light path of lamp portion radiation to reflect to the road surface direction in the centre.So-called restriction light path is exactly for example above-mentioned meaning that like that light path is limited in the direction of regulation.
Thereby prism of the present invention forms the opening surface of growing crosswise in order to be fit to light distribution characteristic.In case make marker lamp horizontal wide consistent with the openend size of lamp portion and prism, then the top and the bottom of the reflector opening end of lamp portion will exceed laterally from prism, cause the ligthing paraphernalia inefficiency of flush identification signal lamp.And if make the reflector opening end size and the above-below direction consistent size of prism of marker lamp with lamp portion, then the left and right directions light quantity of prism again can deficiency, is difficult to obtain required light distribution characteristic.
For this reason, in the present invention, can obtain the degree of required above-below direction luminous intensity distribution, with the top and the bottom of lamp portion openend and optical axis almost parallel scabble, can dwindle the above-below direction size of marker lamp like this with lamp portion, be reduced height, thereby can make the further slimming of flush identification signal lamp.Meanwhile, owing to can make marker lamp consistent with the lateral dimension of prism, it is hereby ensured required left and right directions light quantity with the transverse opening bore of lamp portion.
In addition, further guarantee the occasion of above-below direction light quantity, can make the state that does not intersect with central shaft from the light of bulb to the first half reflecting surface of reflector, and the Lower Half reflecting surface is made the state that intersects from the light of bulb and central shaft in hope.For first half reflecting surface being made the state that does not intersect with central shaft from the reverberation of bulb radiation and this reflecting surface back reflection of incident, to constitute first half reflecting surface with 2 curved surfaces of single rotation, in this occasion, as long as make the axle and the central axes of 2 curved surfaces of rotation, or towards the openend of reflector central shaft being formed certain angle gets final product.In addition, in the occasion that constitutes first half reflectings surface with a plurality of facets with free form surface, the state that the reverberation that each facet can be set for each facet does not intersect with central shaft.
And for the Lower Half reflecting surface of reflector being made the state that intersects from bulb radiation and the reverberation that is mapped to this reflecting surface back reflection and central shaft, to constitute the Lower Half reflecting surface with 2 curved surfaces of single rotation, in this occasion, as long as the axle of 2 curved surfaces of rotation is intersected with central shaft.In addition, also can constitute reflecting surface with a plurality of facets with free form surface.In this occasion, the state that the reverberation that each facet can be set for each facet and central shaft intersect.
When first half reflecting surface and Lower Half reflecting surface have different structure as described above, allow the junction surface of the two to become discontinuous curved surface.
But, in order to limit the optical relation of reflector and bulb, the structural material that preferably clamps lamp holder adhesive one class is fixed.But also can make bulb when needing and on reflector, install and remove freely structure.When adopting this structure, when filament break, can only more change the bulb and the choked reflex device.
And, in such structure, be mapped to the light and the reflection of central shaft almost parallel ground of the first half reflecting surface of reflector from bulb.
Be mapped to the then reflection obliquely upward of light of Lower Half reflecting surface across central shaft from bulb.
Thereby, advance the light face from what the reverberation of first half reflecting surface was generally perpendicularly injected prism.Advance the light face from what the reverberation of Lower Half reflecting surface was injected prism from oblique below.The light of injecting prism respectively reflects according to incidence angle, and penetrates and form elongated light beam (light beam) from prism, and throws to the place ahead of flush identification signal lamp with low angle.And, mainly bear the central shaft Lower Half of reflector from the reverberation of first half reflecting surface.And from the reverberation of Lower Half reflecting surface mainly to bear the central shaft first half of penetrating device.As a result, compare with will going up the same degree of Lower Half reflecting surface, can further improve the light distribution characteristic of above-below direction with the occasion of scabbling.
In addition, when reflector being divided into first half reflecting surface and Lower Half reflecting surface, in order to make reverberation crosscut central shaft from the Lower Half reflecting surface, tilt upward if make the relative central shaft of Lower Half reflecting surface, then can reduce the overhang of reflector Lower Half.This point helps realizing marker lamp (the especially size of downside) miniaturization with lamp portion.
Thereby marker lamp no longer becomes obstruction with the reflector of lamp portion, or the obstruction degree alleviates, and so just can do the light fixture of flush identification signal lamp thinner.
Reflector of the present invention allows first half reflecting surface and Lower Half reflecting surface to be made of a plurality of facets with free form surface respectively.
The present invention is to constitute each reflecting surface with a plurality of facets as mentioned above, so task each facet in case required light distribution characteristic is divided into part branch a plurality of, the light distribution characteristic that will cut apart, just can correspondingly design the free form surface of each facet.Therefore realize required light distribution characteristic easily.
In the present invention, with the scabbling up and down of openend one side of reflector the time, both can earlier the part of first half reflecting surface and Lower Half reflecting surface be scabbled in advance, form reflectance coating then, also can make reflector after forming reflectance coating on the entire emission face, the part that should scabble with suitable means is scabbled then.In addition, above-mentioned " scabbling in advance " also comprises following situation,, the finishing die of matrix made the shape of a part of scabbling reflector that is, just obtained scabbling the structure that should scabble part when being shaped.
In the occasion that the openend of the first half reflecting surface of reflector moves back to one rear flank, top, can make the state that the reverberation from the Lower Half reflecting surface is not repelled by first half reflecting surface.
In said structure, by the solid angle of relative increase Lower Half reflecting surface, to increase reverberation, the light distribution characteristic that easier realization is required from the Lower Half reflecting surface.
In addition, consider, the openend of first half reflecting surface is retreated from laterally seeing obliquely from outward appearance, simultaneously, the openend of Lower Half reflecting surface also with its oblique continuously formation.
And, in this programme, by marker lamp is made the structure of the reverberation crosscut central shaft of first half reflecting surface and separation of Lower Half reflecting surface and Lower Half reflecting surface with the reflector of lamp portion, can reduce the overhang of reflector bottom, therefore can realize the slimming of flush identification signal lamp.
In addition, owing to realized slimming, easily bore operation is implemented on the road surface of imbedding usefulness.But also can realize the lightweight of marker lamp, thereby be convenient to operation.
The flush identification signal lamp of technical scheme 2 is characterised in that, in the marker lamp of technical scheme 1, the foot of bulb with form between difform reflecting surface and the different each other adjacent curvature portion and one lateral openings end, one side is extended the reflector that forms from the top junction surface is oppositely arranged comprising.
In the present invention, so-called " at the junction surface that forms between the different each other adjacent curvature portions " is meant between the adjacent a pair of facet and the part between first half reflecting surface and the Lower Half reflecting surface, because different curved surface is across this junction surface and adjacent, so curved surface is discontinuous at the junction surface.
In addition, so-called " one lateral openings end, one side is extended from the top " be meant when openend one side is seen reflector, is that the center is and forms the junction surface radially with the top.
Also have, the junction surface not only can be the wire that does not almost have width, also can give suitable width in case of necessity.By making the junction surface have certain width, slightly deviation is also harmless even foot is to the setting angle of reflector, is more prone to carry out so assembling is regulated.But,, preferably the junction surface is made light diffusing or light-proofness, so that the light that is mapped to the junction surface is controlled at minimum degree to the influence of luminous intensity distribution in above-mentioned occasion with proper width.In addition, preferably width is controlled at required minimum degree.And to make light diffusing or light-proofness, only need utilize the prior art to get final product.
Secondly,, use the C-8 type that extends along the axle of bulb shield suitable certainly, but the invention is not restricted to this filament, also can obtain effect described later in itself in order to other model filaments headed by the C-6 type about the filament of bulb.
Yet, in case foot's shade of filament reflects on the reflecting surface of reflector, original the luminous of filament was be to be mapped to reflecting surface and to carry out required reflection to be beneficial to luminous intensity distribution, can not be mapped to reflecting surface but repelled by foot because of this luminous part, can cause effective light loss.In addition, also cause the luminous intensity distribution confusion easily.
At this point, the shade of foot of the present invention mainly is mapped to relative junction surface.The junction surface is helpless to required reflection originally, so the loss of effective light quantity takes place hardly.And can not upset luminous intensity distribution.
