FIELD OF THE INVENTION

The present disclosure discloses a device. More particularly, the present disclosure discloses a condensation device for lamps.

BACKGROUND

Generally, there are various types of lighting equipment, for example, lamps, which helps operator to see objects and works/function accordingly. For instance, lamps, such as headlamps illuminate the road ahead of vehicle to allow the driver to see the objects road clearly. In another instance, industrial lamps used in the industries assist the operator to work in night condition.

However, the lamps are susceptible to condensation. The condensation inside the headlamps occurs due to various factors, for example, temperature difference between an inner portion and an outer portion of the headlamps. Generally, air is present inside the headlamps. During ON condition of the headlamps, the air inside the headlamps is heated up and generates heat, which is dissipated by a plurality of vents present in the headlamps. Further, when the headlamps are turned from the ON condition to OFF condition, the plurality of vents traps moisture present in the atmosphere and which leads to the condensation in the headlamps.

The condensation inside the headlamps inhibits light coming from the headlamps, thus impacts visibility of the operator operating the headlamps. The condensation as occurred may also corrode electrical wires inside the lamps. In this regard, many technical solutions are known in the art to reduce condensation in the headlamps. For instance, in a known art, a device with ventilation mechanism using valve, exhaust and desiccant system is disclosed. The desiccant is used to absorb moisture inside the headlamps, thus eliminates condensation. However, this configuration has its own limitation as the desiccant requires a separate sub-housing assembly to assemble in the headlamps, thereby increasing number of components. Further, the assembly of the desiccant increases overall cost of the device.

In another known art, a device with a plurality of membranes and an expandable moisture absorbing means is disclosed. However, this configuration has its own limitation, as the moisture absorbing means expands while absorbing the moisture to reduce condensation inside the headlamps, thus, gradually, the expanding nature of the moisture absorbing means may decrease, which may impact the absorbing capacity of the moisture absorbent means. Further, the configuration as disclosed has complex structure as the device in mounted on a dust cover at central portion of the headlamp. Further, the configuration also needs increased assembly time to assemble the device inside the headlamps. Further, the plurality of membranes are a hydrophilic and hydrophobic membranes which may probably create a problem while absorbing of the moisture by the moisture absorbing means, to reduce the condensation inside the headlamps.

In yet another known art, a device operated on electrical energy is disclosed. The device is configured inside the lamp. The device after getting electrical energy operates and generates heat inside the lamp which diminishes moisture and fogging inside the lamp. However, this configuration has its own limitation that the electrical energy is always needed to operate the device, thus increases load on battery of the vehicle.

In yet another known art, headlamps with halogen and xenon lamp are disclosed which reduces moisture in the headlamps, thus, reduces condensation inside the headlamps. However, this configuration has its own limitation that as the lamps generates more heat, thus, there is chances that if the operator/driver touches the lamp accidentally, they may suffer severe burn.

In yet another known art, a device with moving mechanism is disclosed. However, this configuration has its own disadvantage that continuous power is required to move the device for releasing the moisture outside the headlamp.

Hence, there is a need to provide a condensation device which overcome abovementioned problems.

Referring to Figure 2A-2C, the second portion 202 of the housing 200 extends outwardly with respect to the first portion 201 such that the housing 200 is embodied in an inverted funnel shaped structure. More precisely, the second portion 202 of the housing 200 extends in a predetermined angle with respect to the first portion 201 in a manner that a length of the first portion 201 is smaller than a length of the second portion 202. Further, the plurality of openings 208 is formed at the second portion 202 of the housing 200. More precisely, the plurality of openings 208 includes a first opening 208a and a second opening 208b. The first opening 208a is formed at an end of the second portion 202 of the housing 200. On the other hand, the second opening 208b is formed opposite to the first opening 208a. Further, the baffle 209 is installed in between the first opening 208a and the second opening 208b to separate both the openings from each other. The baffle 209 is installed in a predefined orientation, that is, in slanted/inclined positioned with respect to the first portion 201 in a manner that the baffle 209 forms an inclined path P between the first opening 208a and the first portion 201. More precisely, the baffle 209 forms the inclined path P in a manner that the surface area of the incline path P is larger than a surface area of the second opening 208b.

Further, referring to Figure-2B, the absorbing assembly 210 is disposed in the first portion 201 of the housing 200. The absorbing assembly 210 includes the plurality of membranes 204, 207 and the reactant 206. The plurality of membranes 204, 207 is installed in the first portion 201 of the housing 200. The reactant 206 is disposed between the plurality of membranes 204, 207. The housing 200 includes a holder 205 on the first portion 201 of the housing 200. The holder 205 includes the plurality of membranes 204, 207 on a periphery and the reactant 206 is disposed between the plurality of membranes 204, 207. More precisely, the plurality of membranes includes a first membrane 207 and a second membrane 204. The first membrane 207 is provided on a lower portion of the holder 205. The second membrane 204 is provided on an upper portion of the holder 205. The first membrane 207 and the second membrane 204 is embodied as a one-way polymeric membrane. Further the reactant 206 is placed between the first membrane 207 and the second membrane 204. The reactant 206 is a super hydrophilic crosslinked polymer material.

In one example, referring to Figure 1-2C, when the lamp assembly 100 is in ON condition, the heat/ air as generated inside the lamp assembly 100 is dissipated through a plurality of vents (not shown). Further, the plurality of vents also traps moisture present in the atmosphere in different seasons, for example, rainy season, winter season, or may also trap moisture at time of washing the lamp assembly 100. Further, the moisture as trapped mixed with the air in the lamp assembly 100 and is channelized towards the plurality of openings 208 of the condensation device 104. In an embodiment, the first opening 208a is adapted to allow ingress of the air in the housing 200, that is, the first opening 208a is adapted to transfer the air from the lamp 101 of the lamp assembly 100 to the housing 200.

More precisely, the inclined path P as formed between the first opening 208a and the first portion 202 facilitates channelizing of the air inside the housing 200 and then to the absorbing assembly 210. The inclined path P as formed between the first housing 208a and the first portion 201 is due to the predefined/inclined orientation of the baffle 209 installed between the first opening 208a and the second opening 208b. This configuration ensures the larger surface area of the first opening 208a. Further, the larger surface area of the first opening 208a with respect to the surface area of the second opening 208b, and a temperature difference between the lamp assembly 100 and the condensation device 104 generates pressure difference at the first opening 208a and the second opening 208b. The pressure difference as generates, ensures the ingress of the air through the inclined path P of the first opening 208a.

Further, the absorbing assembly 210 is adapted to remove the moisture/vapor from the air therefrom. More precisely, the plurality of membranes 204, 207 of the absorbing assembly 210 are adapted to receive the air through the inclined path P formed between the first opening 208a and the first portion 201. Further, the reactant 206 receives the air from one of the plurality of membrane 204, 207, where the reactant 206 separate the moisture/vapor from the air. The moisture/vapor as separated is transferred to one of the plurality of membranes 204, 207, where the membrane discharge the moisture/vapor received from the reactant 206 to ambient air. Thus, the plurality of membranes 204, 207 along with the reactant 206 of the absorbing assembly 210 removes the moisture from the lamp assembly 100.

For instance, the air enters in the condensation device 104 and is received by the first membrane 207 of the plurality of membranes 204, 207, through the inclined path P. The air, as received by the first membrane 207, is further transferred to the reactant 206 as the first membrane 207 is a one-way polymeric membrane. The reactant 206 after receiving the air, treat the air and absorbs the moisture present in the air. Further, as the lamp assembly 100 produces heat continuously in the ON condition, thus, the reactant 206 also gets heated up due to the heat generated by the lamp assembly 100. The reactant 206 after getting heated up emit the moisture in the form of the vapour to the second membrane 204.

Further, the second membrane 204 is adapted to receive the moisture/vapor, after treatment of the air by the reactant 206, and discharge the vapor/moisture to the ambient air. More precisely, the second membrane 204 transfers the moisture/vapor outside the condensation device 104 in the atmosphere. Further, the the second opening 208b egress the air, after the moisture/vapor is separated from the air by the reactant 206, from the housing 200.The configuration as disclosed ensures that the moisture is removed in the lamp 101 ON condition, thereby reducing chances of condensation in the lamp assembly 100.

As would be gathered, the condensation device 104 for the lamp assembly 100 offer a comprehensive approach for transferring vapor from the lamp assembly 100 to the atmosphere. As the condensation device 104 is detachably attached with the lamp assembly 100, thus ensures ease of assembly and also provides a simple structure. The present configuration ensures location flexibility for assembling the condensation device 104 on the lamp assembly 100. Further, the present configuration eliminates requirement of any additional components working on electrical energy, thereby, reducing number of components and overall cost of the device. Further, the present configuration also provides ease of replacement of reactant if required.
