The specific embodiment
By reference accompanying drawing and embodiment described later, advantage of the present invention and feature and reach its method will be clear and definite.But, the present invention is not the embodiment that is defined in following discloses, but embody with mutually different variforms, the present embodiment only is provided for making of the present invention open more complete, make the general technical staff of the technical field of the invention easily understand the category of invention, the present invention is only defined by the category of claim.And, in an embodiment of the present invention, for ease of explanation, used identical Reference numeral to describe to identical element.
With reference to the accompanying drawings, the lamps for vehicle device 100 according to the embodiment of the invention is described.
Fig. 1 is the stereogram of lamps for vehicle device according to an embodiment of the invention.
As shown in Figure 1, lamps for vehicle device 100 comprise irradiation light light source portion 110, make the mobile device 130 of the focal length of 120 of lens section 120 that the light refraction of irradiation sees through, change light source portion 110 and lens sections.
A plurality of light sources 111 of irradiation light consist of light source portion 110 by lighting respectively also, and light source 111 is to the field of illumination irradiation light corresponding to predefined direction.Light source portion 110 is disposed at the central portion of lamps for vehicle device 100.But, in other embodiments of the invention, it not is the part of central portion that light source portion 110 also can be disposed at.
The light emitting diode that light source 111 is little by power consumption, luminosity is large (Light Emitting Diode:LED) light source 111 consists of.Light source portion 110 is made of 4 LED sources 111, as described later, makes each LED source 111 to predefined direction irradiation light.Therefore, light source portion 110 is when causing danger situation, and corresponding LED source 111 irradiation light make light only shine corresponding field of illumination.Thereby, dazzling the eyes around not only eliminating, and only highlight corresponding field of illumination to the driver, so can prevent accident.But, in other embodiments of the invention, light source 111 also can use the lamp of the numerous kinds such as Halogen lamp LED and high intensity discharge (HID) lamp.
In addition, the edge of the rear side of lens section 120 is provided with the mobile device 130 that lens section 120 is moved.
Fig. 2 shows the according to an embodiment of the invention view of the field of illumination of lamps for vehicle device.
As shown in Figure 2, lamps for vehicle device 100 is respectively installed one about the front side of vehicle, to the vehicle front irradiation light.
A plurality of LED sources 111 are arranged to by predefined field of illumination irradiation light.Therefore, as supplying power supplys to LED source 111, then corresponding LED source 111 arouses driver's attention to corresponding field of illumination irradiation light.
A plurality of LED sources 111 are lighted discriminably, both can be only to field of illumination irradiation light, and also can be to a plurality of field of illuminations irradiation light.Therefore, owing to only to the field of illumination irradiation light at object place, only highlighting object to the driver, can prevent accident.
Be arranged at the lamps for vehicle device 100 of vehicle left side to the left forward side of vehicle and the field of illumination irradiation light of the place ahead center side.Simultaneously, be arranged at the lamps for vehicle device 100 on vehicle right side to the right forward side of vehicle and the field of illumination irradiation light of the place ahead center side.
Fig. 3 shows the according to an embodiment of the invention schematic representation of light source portion.
As shown in Figure 3, light source portion 110 is made of 4 LED sources 111 as mentioned above according to an embodiment of the invention.But, in other embodiments of the invention, light source portion 110 can be made of the LED source 111 that surpasses 4 of 4 or less thaies.
In addition, each LED source 111 has preseted the direction of illumination of light.Therefore, 111 of each LED sources are to corresponding field of illumination irradiation light.That is, owing to each LED source 111 is lighted respectively, so when recognizing object in corresponding field of illumination, only have corresponding LED source 111 to light.
Fig. 4 a is the view that shows the light range of exposures that is determined by focal length of lamps for vehicle device according to an embodiment of the invention, Fig. 4 b is the view that shows the light range of exposures that is determined by focal length of lamps for vehicle device according to an embodiment of the invention, Fig. 5 a is for showing the view according to the luminous intensity distribution pattern shown in Fig. 4 a, and Fig. 5 b is for showing the view according to luminous intensity distribution pattern shown in Fig. 4 b.
Shown in Fig. 4 a to Fig. 5 b, lamps for vehicle device 100 only when the focal length of 120 of light source portion 110 and lens sections is in the set scope, just can makes light be concentrated on the field of illumination and shine according to an embodiment of the invention.And, in the present embodiment, the scope of the focal length that light source portion 110 and lens section are 120 below the above 60mm of 5mm.But, according to various embodiment of the present invention, the scope of focal length can have multiple variation.
In the time of in focal length is in set scope, light source portion 110 sees through lens section 120 to the light of four directions irradiation, thereby shows the luminous intensity distribution pattern that is concentrated on corresponding field of illumination.
The focal length that light source portion 110 and lens section are 120 as mentioned above, 130 mobile lens sections 120 regulate by mobile device.Therefore, if the distance of 110 of lens section 120 and light source portion is approached, break away from the focal length of light, then show through the light of lens section 120 optically focused not, but high beam (High Beam) the luminous intensity distribution pattern of diffusion.
Therefore, the driver is operating moving device 130 consciously, is spotlight (Spot Light) luminous intensity distribution mode altering high beam (High Beam) luminous intensity distribution pattern.
The following describes the effect of the lamps for vehicle device 100 of the present invention that as above consists of.
Fig. 6 has installed the according to an embodiment of the invention schematic representation of the vehicle of lamps for vehicle device additional for showing.
As shown in Figure 6, at first, near infrared ray (NIR) camera 300 perception that are disposed at vehicle front side are in the objects such as human or animal of vehicle front side, and the information of perception is sent to electronic control unit (Electronic Control Unit:ECU) 200.Electronic control unit 200 is to the LED source corresponding with the field of illumination, object place of perception 111 supply power supplys, to corresponding field of illumination irradiation light.But, when a plurality of objects are distributed in different field of illumination, to each LED source 111 supply power supplys corresponding to each field of illumination, thereby to each field of illumination irradiation light.At this moment, so the light of lamps for vehicle device 100 irradiation spotlight luminous intensity distribution patterns is the clear identification object of driver.
In addition, the driver can utilize mobile device 130, breaks away from the focal length of 110 of lens section 120 and light source portion, so that the light of irradiation high beam luminous intensity distribution pattern.
Above each embodiment is not intended to limit only in order to technical scheme of the present invention to be described; Although with reference to aforementioned each embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of various embodiments of the present invention technical scheme.
