As concrete structure, as shown in Figure 2, aircraft warning light 10 mainly comprises: for example be arranged to only expose lamp body 11 on the ground, be installed in the bottom of this lamp body 11 and imbed base station 12 in the ground, be installed in this lamp body 11 below, be used for sign lamp lamp 1A by establishing in 6 pairs of the fixtures, the installed part 13 that 1B fixes, be installed between this installed part 13 and the above-mentioned lamp body 11, adopt the sign lamp lamp 1A of the present invention of a plurality of LED formations as light source, 1B will identify lamp lamp 1A from these, the irradiates light that 1B sends makes sign lamp lamp 1A when predetermined direction is shone, 1B has the optical component 14a of guide effect.In addition, in this example,, also can constitute employing prism etc. in case of necessity and carry out light path control though above-mentioned optical component 14a is the characteristic that sees through the light that sends with lamp 1A, 1B from the sign lamp as only having.
Above-mentioned sign lamp as light source shines respectively in opposite direction with the light that is configured to relatively in lamp 1A, the 1B structure shown in the figure shine.
In addition, be contained in and respectively identify lamp and be connected with not shown power supply unit by the figure on the base material, stube cable and main distribution cable (being called supply lines), and supply with tonal range signal (being the luminous necessary electric current of LED) through power supply unit with a plurality of LED 5 among lamp 1A, the 1B.Be connected with above-mentioned power supply unit thus, and above-mentioned sign lamp controlled with the luminous of a plurality of LED 5 lamp 1A, the 1B according to the operation indication of the control part that sends from the control tower.
In addition, fixed respectively by the fixed part 13a that is installed between lamp body 11 and the installed part 13 as shown in the figure with each optical component 14a that lamp 1A, 1B are provided with corresponding to above-mentioned sign lamp.In addition, the part in the place ahead of these optical components 14a that is positioned at lamp body 11 is formed with respectively and is used to make the opening slot part 11a of light along the predetermined direction irradiation.
In addition, though in this example, with lamp 1A, 1B each light is described along the aircraft warning light 10 of variant direction irradiation to identifying lamps with 2, but for example needn't 2 in center, the guiding road lamp of direction irradiation, also can constitute and 1 sign lamp only is set with lamp 1A and make and be scheduled to light and shine along 1 direction.
Yet, in the aircraft warning light of this example, it is characterized in that mounting has as the sign lamp lamp 1A, the 1B that are used to solve the in-problem device of above-mentioned conventional art.Followingly specify this sign lamp lamp of the present invention with reference to Fig. 1.
As shown in Figure 1, sign lamp of the present invention constitutes to be provided with lamp 1A (1B) a plurality ofly installs the LED unit 2 that a plurality of LED 5 constitute as light source, and is configured to obtain required luminous intensity distribution figure.
Though LED unit 2 is not shown, comprise but constitute: the lenticular resins of illuminated portion that can be by change constituting LED change a plurality of LED5 of the optical characteristics of the direction of illumination of the light that illuminating part internally sends etc., be used for configuration plate 3 that these a plurality of LED 5 are set up in parallel with predetermined installing figure, can be by the base material 4 of a plurality of LED 5 of configuration plate 3 installings.
In addition, above-mentioned a plurality of LED 5 also can adopt the luminous LED of a plurality of colors of energy, also can be configured to obtain required luminous color or change configuration as required on suitable configuration plate 3.
For example, constitute the occasion of sign lamp, become sign lamp lamp 1A shown in Figure 1 with lamp at 3 LED unit 2a that adopt this formation, 2b, 2c.These LED unit 2a, 2b, 2c are provided as and obtain the predetermined required configuration of luminous intensity distribution figure, has the occasion of roughly the same light distribution characteristic at these, as shown in Figure 1, fan-shaped by 3 LED unit 2a, 2b, 2c are configured to respect to direction of illumination, can obtain required luminous intensity distribution figure.
In addition, have the occasion of different light distribution characteristics at 3 LED unit 2a, 2b, 2c, the configuration of the LED by changing the optical characteristics be contained in the LED itself in each LED unit or each LED unit of appropriate change as required itself also can obtain required luminous intensity distribution figure.
In this example, in configuration and the occasion of above-mentioned a plurality of LED unit is set, form overlapping at oblique line part 20a shown in Figure 3 each LED unit 2a, 2b, 2c configuration and each luminous intensity distribution zone of each LED 5 irradiations of being arranged to for example make LED unit 2a, 2b, the 2c of adjacency.
Therefore, the sign lamp of above-mentioned formation obtains the light distribution characteristic that irradiation has the LED light of directive property with lamp 1A with as shown in Figure 3 luminous intensity distribution, consequently can obtain the luminous intensity distribution figure of stipulating 20 simply.
In addition, about with above-mentioned sign lamp sign lamp lamp 1B with the opposing party of the relative configuration of lamp 1A, its formation and optical effect are identical with above-mentioned sign lamp usefulness lamp 1A.
Therefore, adopt this example,, can make the light source long lifetime, and the consumption concerned power can realize economizing electrification owing to constitute above-mentioned a plurality of LED unit 2a, 2b, the 2c that adopts LED as light source.In addition, owing to can obtain required luminous intensity distribution figure simply by light distribution characteristic and the configuration that only changes these a plurality of LED unit 2a, 2b, 2c, can not need as the conventional art corresponding to of the formalities such as prism that light distribution characteristic is selected or configuration has the refraction angle that satisfies predetermined light distribution characteristic of sign lamp with lamp.
In addition, occasion at the light distribution characteristic that requires to shine wider range, because only a plurality of LED being configured in unidirectional sign lamp is to shine near the gabarit of luminous intensity distribution figure of this requirement in lamp, thereby produce the luminous intensity distribution loss, and make the luminous efficiency deterioration, but in this example, constitute sign lamp lamp 1A as light distribution characteristic being changed into make, the LED unit 2a of the both sides of 1B, 2c, 2d, the light distribution characteristic of 2f is a narrow angle, promptly the characteristics of luminescence of each LED5 of Dui Ying LED unit itself becomes narrow angle, then can not produce the luminous intensity distribution loss, and can obtain identical luminous intensity distribution figure, its result can improve luminous efficiency.
Yet in aircraft warning light of the present invention, the sign lamp that can not change institute's mounting easily changes to required luminous intensity distribution figure with the configuration of each LED unit of lamp.Fig. 4 illustrates this example.
Fig. 4 for expression the present invention identify lamp with the 2nd example of lamp, be used to illustrate the key diagram that this sign lamp is improved the characteristics of luminescence of occasion with each LED unit of lamp.
In this example, roughly the same about the sign lamp with the aircraft warning light 10 of formation beyond each LED unit 2a-2f of lamp 1A, 1B and above-mentioned the 1st example, difference is, it is characterized in that constituting by changing above-mentioned sign lamp easily obtaining required luminous intensity distribution figure with the characteristics of luminescence of the LED5 of the preset range of each LED unit 2a-2f of lamp 1A, 1B.
Specifically, as shown in Figure 4, the sign lamp constitutes in each set LED unit 2a, the setting area of LED 5 on 2b, the 2c with lamp 1A, to change the narrow angle LED 5as of installing with the LED 5 of the outer periphery that is equivalent to this setting area setting area 16 (setting area of representing with oblique line among Fig. 4) counterpart partly for having the narrow angle characteristics of luminescence, on the other hand, will change and the Wide-angle LED 5b of installing with the LED 5 of the setting area 15 that is centered on by its setting area 16 (setting area beyond Fig. 4 bend) counterpart for having the wide-angle characteristics of luminescence.
In addition, though narrow angle LED 5a or Wide-angle LED 5b are not shown, but all be the lenticular resins of the illuminated portion by will constituting LED change into narrow angle with or wide-angle be narrow angle or wide-angle with the direction of illumination angle initialization of the light of illuminating part that will be internally, and acquisition becomes the optical characteristics of feature separately.
In addition, though illustrated in this example is in each LED unit 2a, 2b, 2c above-mentioned narrow angle LED 5a and Wide-angle LED 5b to be installed in the setting area 16 of the outer periphery part that is equivalent to whole setting area, LED unit and the occasion in the setting area 15 beyond it respectively, but be not limited to this, and can do suitable change as required.For example, make narrow angle LED 5b as all LED of the LED unit 2b that will be configured in the center, and the LED of LED unit 2a, the 2c of both sides mixes installing narrow angle LED 5a and Wide-angle LED 5b, then the luminous intensity distribution figure that also can obtain to become clear than the vicinity, center with predetermined space.
Adopt this formation, for example compare the occasion of the luminous intensity distribution figure 21 that narrower scope shines, need not to change Optical devices such as prism and can easily obtain above-mentioned luminous intensity distribution figure 21 as each LED unit 2a of light source, the configuration of 2b, 2c at the luminous intensity distribution figure 20 (with reference to Fig. 3) that requires to be obtained with above-mentioned the 1st example.In this occasion, luminous intensity distribution figure 21 is because other narrow angle of branch LED 5a of LED unit 2a, the 2c of both sides, the luminous intensity distribution of both sides only is very narrow oblique line part, and in addition, the luminous intensity distribution of vertical direction is also owing to other narrow angle of branch LED 5a of each LED unit 2a, 2b, 2c becomes narrower.
In addition, as comparing with lamp and light distribution characteristic thereof with the sign lamp that only a plurality of LED is configured in unidirectional conventional art, its difference is significantly, that is, owing to there is not the luminous intensity distribution loss, so can improve luminous efficiency, this is mathematical.
In addition, about identifying lamp lamp 1B with above-mentioned sign lamp with the opposing party of the relative configuration of lamp 1A, its formation is identical with lamp 1A with above-mentioned sign lamp with optical effect.
Therefore, adopt this example, obtain with above-mentioned the 1st example effect same outside, need not to change the sign lamp and can easily change required luminous intensity distribution figure with the configuration of each LED unit of lamp, can further improve luminous efficiency.
Yet, in the above-mentioned the 1st and the 2nd example, though, also can adopt the LED unit more than 3 to constitute in the present invention, and light distribution characteristic is further improved to adopting 3 LED unit formation sign lamps to be described with the occasion of lamp.This example as shown in Figure 5.
Fig. 5 represents that the present invention identifies 3rd example of lamp with lamp and aircraft warning light, and wherein, Fig. 5 (a) is the front view of this sign lamp with lamp, and Fig. 5 (b) is the sectional drawing of this sign lamp with lamp.
In this example, by with a plurality of, for example 10 the diverse LED of light distribution characteristic unit are configured in relative with direction of illumination and on the configuration plate 3 of convex surface, are with the formation of lamp 30 and the difference of above-mentioned example as the sign lamp.In addition,, also equally 2 sign lamps are uploaded at aircraft warning light with lamp 30 and are set to relative configuration shape, be simplified illustration, only a side the sign lamp structure with lamp is described with above-mentioned example even in this example.
As shown in Figure 5, the sign lamp of this example comprises with lamp 30: and nose circle edge towards convex surface and general about relative with direction of illumination excises, is divided into the configuration plate 3 and the base material 4 of each LED unit along level, dispose 5 LED unit 33a-33e, 34a-34e by this configuration plate 3 respectively in last shadow surface 33 sides and following shadow surface 34 sides, the cylindrical portion 35 that the lead that extends along the back side of the base material 4 that these LED unit are installed, will power to each LED 5 of these LED unit is drawn; Above-mentioned configuration plate 3 and base material 4 are benchmark with central portion 32, form the last shadow surface 33 and the following shadow surface 34 that shine the light that sends from each LED unit.
Above-mentioned upward shadow surface 33 is split into a plurality of LED unit 33a-33e with following shadow surface 34 and also installs into multi pin sight (Japanese: the reflecting surface of formula multiaspect Off ォ ア セ ッ ト) respectively with 34a-34e, according to the free curve of each LED unit 33a-33e and 34a-34e, being set at can be the main luminous intensity distribution that obtains with respect to the predetermined luminosity of horizontal angle with the light distribution characteristic of predetermined dimension.
In addition, the light distribution characteristic of each unit among these LED unit 33a-33e and the 34a-34e has nothing in common with each other, when the luminous occasion in each LED unit obtains required luminous intensity distribution figure, also have these luminous intensity distribution graphics overlays respectively and the light distribution characteristic of the synthetic luminous intensity distribution figure that obtains to be generated.This occasion, what a plurality of LED 5 of LED unit adopted is that each LED unit has the optical characteristics of identical luminous intensity distribution, in addition, the difference of the light distribution characteristic of each LED unit also can change the lenticular resins of each LED unit as above-mentioned the 1st example.In addition, as above-mentioned the 1st example, the characteristic that the light that the light distribution characteristic of each LED unit sends for each LED unit is overlapping respectively.
In addition, though the light distribution characteristic for above-mentioned whole LED unit in this example is described for the situation that each unit has nothing in common with each other, but be not limited to this, for example also can be above-mentioned each LED unit 33a-33e that goes up shadow surface 33 and following shadow surface 34 each LED unit 34a-34e light distribution characteristic distinguish relative characteristic.
The sign lamp of at least 1 this structure is positioned in the aircraft warning light shown in Figure 2 with lamp 30, promptly makes aircraft warning light of the present invention.
In this example, same with above-mentioned the 1st example, shine light in each LED unit through optical component 14a shown in Figure 2, opening slot part 11a, a part of light is overlapping and form the luminous intensity distribution figure.Though the luminous intensity distribution figure of this occasion is not shown, become the synthetic luminous intensity distribution figure that some luminous intensity distribution graphics overlays form, luminous efficiency is more good.
Therefore, adopt this example, decapacitation obtain with the same effect of above-mentioned the 1st example outside, can also constitute the more good aircraft warning light of luminous efficiency.
In addition, though above-mentioned LED unit 33a-33e, 34a-34e are installed on the level and smooth curve form, has the shape that different curve is engaged with the border of the LED unit of adjacency.For example, the in-problem occasion of luminous intensity distribution figure at LED unit 33a, can carry out the location relative by curved surface and adjust to set again solving to LED unit 33a with the cylindrical element 35 of corresponding assortment substrate 3 and base material 4, and need not to consider the light at random that sends from the LED unit of adjacency, so that the setting of the curve form of LED unit becomes is easy.
