Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.In description, same or analogous drawing reference numeral represents same or analogous parts.Followingly with reference to accompanying drawing, the explanation of the utility model embodiment is intended to overall utility model design of the present utility model to make an explanation, and does not should be understood to a kind of restriction of the present utility model.
Fig. 1 is schematically illustrated such as, according to the illumination of an embodiment of the present utility model and/or signal indicating device 100, headlamp, the signal lamp etc. of motor vehicles.This illumination and/or signal indicating device 100 can comprise light source 1 and housing 2.This light source 1 can be for example incandescent lamp, LED lamp, xenon lamp etc., for launching for throwing light on and/or the visible ray of signal designation and the infra-red radiation of following.This housing 2 is for holding described light source 1 and being provided with light outgoing portion 21, for example outer lens, and the visible ray sending from light source 1 can penetrate from described smooth outgoing portion 21, to realize illumination and/or signal designation function.As shown in Figure 1, housing 2 has surrounded certain space, and this space comprises the first subspace 31 and the second subspace 32.Light source 1 is arranged in described the first subspace 31, described the second subspace 32 and the first subspace 31 are separated by the first selective transmission separator 41, described selective transmission separator 41 can block at least most visible ray and at least in part transmission infra-red radiation so that the infra-red radiation sending from light source 1 can be transmitted to the second subspace 32 from the first subspace 31.
It should be noted that, the first subspace 31 as herein described and the second subspace 32, must not be the subspace of sealing, between the first subspace 31 and the second subspace 32, must do not separated completely yet.For example both can partly be kept apart by selective transmission separator 4, and between them, leave certain opening, and certainly, the first subspace 31 and the second subspace 32 also can fully be kept apart by selective transmission separator 4.
In the time throwing light on and/or signal indicating device 100 is worked, the visible ray that light source 1 sends is realized corresponding function from the 21 ejaculation illuminations of light outgoing portion and/or signal indicating device 100 to arrive illumination and/or signal designation region.Meanwhile, this visible ray and the infra-red radiation of following also make the temperature in the first subspace 31 raise, thereby cause the temperature difference between the first subspace 31 and the second subspace 32.If visible ray and infra-red radiation can not promptly be passed to heat the second subspace 32, the temperature difference between the first subspace 31 and the second subspace 32 is by highly significant.Especially, when the temperature in the second subspace 32 is during lower than set point, air in the first subspace 31 and steam with the second subspace 32 in the air of low temperature and steam while meeting, or while reaching near the low-temperature region the second subspace 32, may produce condensation.When this condensation effects occurs in the subspace for example, abutting with light outgoing portion 21 (outer lens) or on the wall of light outgoing portion 21, especially large for the impact of illumination and/or signal designation effect.
And owing to being provided with selective transmission separator 41, the problems referred to above are avoided or are at least obviously alleviated.Because selective transmission separator 41 can be transmitted through the infra-red radiation of small part, so the infra-red radiation sending from light source 1 (as shown in label Fig. 1 611) can enter into the second subspace 32 to promote the temperature of the second subspace 32 from the first subspace 31.Nonetheless, the temperature of the second subspace 32 still may be lower than the temperature of the first subspace 31, and still the difference of the temperature of the second subspace 32 and the temperature of the first subspace 31 will be dwindled significantly.In an example, the temperature of the second subspace 32 can be elevated to the set point of steam above and temperature is remained on to the set point of steam more than, thereby prevent the generation of condensation.Because visible ray in the work of illumination and/or signal indicating device 100 is work light, therefore, the loss of visible ray is disadvantageous for operating efficiency.And, if optionally entering certain sub spaces, visible ray may cause less desirable interference to illumination and/or signal designation function in addition.Therefore, selective transmission separator 4 is not completely transparent for visible ray, but can block at least most visible ray, and for example, selective transmission separator 4 can absorb or reflect visible light at least in part or fully.
In an example, the second subspace 32 can abut light outgoing portion 21, as shown in Figure 1.And in another example, as shown in Figure 2, the space that described housing 2 surrounds can also comprise the 3rd subspace 33, described the 3rd subspace 33 abuts light outgoing portion 21.The 3rd subspace 33 and the second subspace 32 are separated by the second selective transmission separator 42, described the second selective transmission separator 42 can block at least most visible ray and at least in part transmission infra-red radiation so that infra-red radiation can be transmitted to the 3rd subspace 33 from the second subspace 32.Between described the 3rd subspace 33 and the first subspace 31, can also there is the path 332 (for example, opening between the 3rd subspace 33 and the first subspace 31) that allows visible ray to pass through, as shown in Figure 2.Utilize the combination of the first selective transmission separator 41 and the second selective transmission separator 42, can more in depth change the inhomogeneities of the Temperature Distribution in housing 2.In the design of illumination and/or signal indicating device, may there are some subspaces (for example the 3rd subspace 33) although can by a part of radiation of visible light to but still can there is the obvious temperature difference with the first subspace 31, and owing to may be used for realizing illumination and/or signal designation function through the visible ray in these subspaces, therefore, this temperature difference is also particularly evident for the impact of the optical effect of illumination and/or signal designation.And by means of the combination of the first selective transmission separator 41 and the second selective transmission separator 42, can make the temperature of the second subspace 32 and the 3rd subspace 33 all raise quickly, the adverse effect for optical effect causing to suppress temperature difference.
And the infra-red radiation that light source 1 sends not is work light for illumination and/or signal indicating device 100,100 ', therefore the temperature of, utilizing infra-red radiation to promote the second subspace 32 and even the 3rd subspace 33 can not produce adverse influence to illumination and/or signal designation function.
The first and/or second selective transmission separator 41,42 can be special parts, can be also the parts that have other function concurrently.For example, the described first and/or second selective transmission separator 4 can be scale or shadow shield.It can be for reflection, absorb visible ray or for regulating the distribution of visible light intensity.
In an example, the first and/or second selective transmission separator 41,42 can be made up of polymer, for example Merlon or polyamide, and this kind of material for example can obtain from Beyer Co., Ltd.In an example, the first and/or second selective transmission separator 41,42 at least in part transmission peak wavelength is greater than the radiation of 700nm, or transmission peak wavelength is greater than the radiation of 800nm.In an example, the first and/or second selective transmission separator 41,42 transmissivities for infra-red radiation can be not less than 50%, are not less than 60%, are not less than 70%, are not less than 80%, or not even lower than 90%.
In the application's embodiment, the first selective transmission separator 41 and the second selective transmission separator 42 can have identical material and/or structure, also can adopt different materials and/or structure according to the needs of temperature control and structural design.
Fig. 3 illustrates according to the illumination of another embodiment of the present utility model and/or signal indicating device 100 ' '.Compared with the illumination shown in Fig. 2 and/or signal indicating device 100 ', this illumination and/or signal indicating device 100 ' ' the main distinction be, it also comprises the reflector 5 being arranged in housing 2, and this reflector 5 can reflex to the first selective transmission separator 41 from the first subspace 31 by least a portion of the infra-red radiation sending from light source 1.In embodiment as shown in Figure 3, not only have the infra-red radiation (being indicated by label 611) from light source 1 direct directive the first selective transmission separator 41 among Fig. 3, and reflector 5 also reflects a part of infra-red radiation (being indicated by label 612 in Fig. 3) to the first selective transmission separator 41.Like this, enter the second subspace 32 infra-red radiation measure strengthen.In an example, the amount of infrared radiation being reflected on described the first selective transmission separator 41 can exceed predetermined threshold value, and this threshold value because usually determining, for example, can be 1mW/cm according to power and the amount of thermal conduction etc. of light source
2, 5mW/cm
2, 10mW/cm

2etc..This reflector 5 can be special reflector, can be also the parts that have other function concurrently.For example, this reflector 5 can also be configured to for throwing light on and/or the visible ray of signal designation carries out luminous intensity distribution and/or collimation.
In an example, in order to make the amount of infrared radiation being reflected on the first selective transmission separator 41 exceed predetermined threshold value, reflector 5 can also comprise infra-red radiation luminous intensity distribution portion 51, described infra-red radiation luminous intensity distribution portion 51 can further strengthen the amount of infrared radiation being reflected on the first selective transmission separator, thereby the temperature of the second subspace 32 can more promptly be raise.In the example described in Fig. 2, on the reflecting surface of described infra-red radiation luminous intensity distribution portion 51 by reflector 5, outstanding faceted pebble forms, but this not necessarily, described infra-red radiation luminous intensity distribution portion 51 also can, by the structure of the other types on the reflecting surface of reflector 5, form as raised or sunken.In practice, infra-red radiation luminous intensity distribution portion 51 likely can exert an influence to the light distribution of visible ray.Avoid such impact, optical design that on the one hand can be based on illumination and/or signal indicating device and infra-red radiation luminous intensity distribution portion 51 is arranged on illumination and/or signal designation influential effect is less or without the position of impact; Luminosity compensation structure (for example arrange) also can be set on the other hand to compensate infra-red radiation luminous intensity distribution portion 51 to for throwing light on and/or the impact of the light distribution of the visible ray of signal designation on reflector 5.
