Description

Have the LED Vehicle lamp structure of anti-fog and aqueous vapor concurrently

Technical field

The utility model relates to a kind of LED Vehicle lamp structure that has anti-fog and aqueous vapor concurrently, refers to especially have the LED Vehicle lamp structure that prevents that fog and aqueous vapor from producing.

Background technology

Because light emitting diode (LED) has multiple advantages such as low power consumption, long service life, in at present known luminescence component, be widely used in various light-emitting device as light source, therefore present car light design also adopts this High Power LED as light source.

Yet with the Vehicle lamp structure of light emitting diode as the LED of light source, it is made of lens of car light and a base, and wherein these lens and this base link into an integrated entity, and define an enclosure space jointly.At least one light emitting diode is on the base that is arranged in this airtight chamber, the projecting direction of its light source is towards lens, but because should be with the car light of LED as light source, its Vehicle lamp structure is complete closed but does not take out with air and aqueous vapor and make it be vacuum state when making, cause and still depositing a little aqueous vapor in the Vehicle lamp structure, therefore the influence after being subjected to temperature or weather when early morning, moisture was serious (as rainy day or) or carwash, the car light Nei Changyin temperature difference or moisture or water droplet enter and produce fog or the globule that condenses, and these fogs and the globule are attached on the surface within the lens of car light, often the user need open car light, make the light of car light penetrate outward, water smoke is disappeared towards lens of car light.

Aforesaid light is through only concentrating on a zonule of lens of car light on the lens of car light, cause the temperature of light source to concentrate on this zonule, the fog or the globule after after a while on this zonule slowly are evaporated disappearance, yet the lens of car light in the outside, light district is then because of causing its temperature lower away from the light source irradiation area, the internal-external temperature difference of these lens is bigger in addition, easily make the interior remaining aqueous vapor of car light have the phenomenon of the fog or the globule to produce in this zone, and then influence brightness and the illumination zone that car light penetrates, also may cause the fault of light emitting diode or damage and attractive in appearance on not good.

Because the said goods every shortcoming of deriving, the creator of this case exhausts its intelligence then, concentrates on studies and innovate improvement, and successfully research and development are finished the utility model and had anti-fog and aqueous vapor LED Vehicle lamp structure concurrently finally, and reality is one to have the creation of enhancement effect.

The utility model content

For solving the shortcoming of above-mentioned common technology, the main purpose of this creation, provide a kind of LED Vehicle lamp structure that has anti-fog and aqueous vapor concurrently, at the indoor fan that is provided with of the enclosed cavity of car light group, make the indoor gas flow of enclosed cavity by this fan, make indoor temperature of enclosed cavity and gas evenly distribute by this.

A feasible embodiment is provided is a kind of LED Vehicle lamp structure that has anti-fog and aqueous vapor concurrently in order to reach above-mentioned purpose the utility model, it comprises: a car light group, have a base and a printing opacity clamshell, this printing opacity clamshell is located at relatively that the place ahead and this base of this base link into an integrated entity, and defines one and seal chamber and be formed between this base and the printing opacity clamshell;

At least one light-emitting diode (LED) module, having a main body base is connected with this base, this main body base is provided with plural light emitting diode, and the luminous end of these light emitting diodes is towards this printing opacity clamshell, so that the light of these light emitting diodes is gone out through this printing opacity clamshell transmission from this luminous end; A fan, connect this base and be located at enclosed cavity indoor, to make the indoor gas flow of this enclosed cavity.

The specific embodiment

The utility model provides a kind of LED Vehicle lamp structure that has anti-fog and aqueous vapor concurrently, graphicly is this creation preferred embodiment, sees also Fig. 1, shown in Figure 2 comprising and is provided with at least one light-emitting diode (LED) module 20 and a fan 30 in the car light group 10.

Described car light group 10 has a base 11 and a printing opacity clamshell 12, and this printing opacity clamshell 12 is located at this base 11 the place aheads relatively, and links into an integrated entity with

base

11, and 13 of a chamber of sealing is formed between this base 11 and the printing opacity clamshell 12.

Described light-emitting diode (LED) module 20, having a main body base 21 is connected with this base 11, this main body base 21 is provided with plural light emitting diode 22, the luminous end of this plural number light emitting diode 22 is towards this printing opacity clamshell 12, goes out through these printing opacity clamshell 12 transmissions from this luminous end with light that should plural number light emitting diode 22.

Described fan 30 connects base 11 and is located at and seals in the chamber 13, shows that in Fig. 2 this fan 13 is connected the right side of base 11, but be not limited thereto that any side that also can be located at base 11 is avoided the appropriate location of this light-emitting diode (LED) module 20.Described fan 30 can be axial flow fan or centrifugal fan, and Fig. 2 is shown as axial flow fan, and has impeller 32 of a framework 31 its interior pivot joints.

After this car light group 10 starts, the light of this light emitting diode 22 is concentrated through these printing opacity clamshell 12 transmissions from this luminous end and is gone out, this fan 30 is while or asynchronous running when this car light group starts, gas in this sealing chamber 13 then flows along with fan 30 operates in the sealing chamber 13, gas in the order sealing chamber 13 circulates under the state that does not externally flow, and then this gas and temperature are evenly distributed in sealing chamber 13, also this this printing opacity clamshell 12 is not reached under the uniform situation of temperature because of gas circulation in the chamber flows by the zone that car light light shines, and can not make lens have the phenomenon of fog and condensation of moisture to produce away from the place of irradiated region.

With reference to shown in Figure 3, the main body base 21 of described light-emitting diode (LED) module 20 can be connected with a radiator 23, is dispelled the heat to make this light-emitting diode (LED) module 20 in addition.

With reference to shown in Figure 4, described light-emitting diode (LED) module 20 and this fan 30 electrically connect a control device 40 respectively in addition, by the startup of these control device 40 these light-emitting diode (LED) modules 20 of control and this fan 30 and close.

By above-mentioned structure, it is as follows that the utility model is compared the improvements of prior art:

Utilize the gas flow in the fan 30 order sealing chambers 13, and gas so that gas and temperature are evenly mixed, can because of the temperature difference not produce fog or the phenomenon person of the condensation of moisture to make inner lens surfaces in circulation in sealing chamber 13 under the state that does not externally flow.

Though the utility model discloses as above with embodiment, yet it is not in order to limiting the utility model, anyly is familiar with this skill person, in the spirit and scope that do not break away from this creation, be used as the equivalent action of various change and retouching, all should be included in the interest field of the present utility model.
