Description:TECHNICAL FIELD
[001]
The present subject matter is related to a lamp assembly, in particularrelated to the lamp assembly for automotive domain.
BACKGROUND
[002]
Typically, in a vehicle a plurality of lamps is provided to throw light rays5 on the road and to enhance the visibility of the users and others traveling on the road. The plurality of lamps can be provided on the front and the rear end of the vehicle to illuminate the road for the users in night or foggy conditions. The plurality of lamps may be individually positioned at different locations or be provided as a single integrated lamp assembly unit. Conventionally the lamps are provided with an 10 assembly of components which then in totality becomes a head lamp or a rear lamp. The components such as a plurality of LEDs (light emitting device), a control unit, a plurality of heat dissipation device and a bezel lens.
[003]
The head lamp assembly of the vehicle plays a crucial role in ensuringvisibility and safety during low-light conditions. It consists of various components, 15 including the housing, bulbs, reflectors, lenses, and wiring, all working together to provide adequate illumination for the driver and others on the road.
[004]
Low visibility head lamps can pose serious safety concerns for drivers. Dimor low-intensity headlights can reduce the driver's ability to see the road ahead, obstacles, and other vehicles. Over time, head lamp lenses may become yellowed or 20 clouded due to exposure to sunlight, reducing the clarity of the light output. If the head lamps are not properly aligned, they may not illuminate the road evenly, leading to dark spots or glare for oncoming drivers and a burned-out bulb can significantly diminish the overall brightness of the head lamp assembly, which later results to
3
impacting visibility.
[005]
Damaged or inefficient reflectors within the head lamp assembly can resultin poor light projection. Further, during low light riding conditions reflectors of the vehicles in front may not be functional.
[006]
Multiple head lamps allow for higher illumination intensity, improving the5 driver's ability to see and be seen in various driving conditions, especially in low-light or adverse weather situations and dual or triple head lamp setups can be designed to ensure even distribution of light on the road, reducing the risk of dark spots or shadows In addition to functionality, multiple head lamps can contribute to the overall aesthetic appeal of a vehicle, providing a distinctive and recognizable 10 front-end design.
[007]
In recent times, the requirement of high-power lamps is to improve drivingsafety by illuminating more of the road in front of drivers due to imminent increase in traffic. These high-power lamps use high power LEDs to achieve desired range of light emission on the road, to achieve the desired performance of the lamps proper 15 heat dissipating device is also necessary. Conventionally the plurality of heat dissipating device is provided in the lamp assembly which are manufactured as per shape and size of the LEDs, generally in a lamp assembly one or more heat dissipating devices are provided which tends to increase the weight of the whole assembly. 20
[008]
Generally, the heat dissipating devices are manufactured out of Bauxitealloy, typically of Aluminium material. In the high-power LEDs head lamps to achieve thermal conductivity, it requires more amount of Aluminium to manufacture the heat dissipating device which can be installed in the lamp assembly. But adding
4
more quantities of Aluminium tends to increase the weight and the cost of
manufacturing.
[009]
Later, this type of assembly in which the LEDs are of more intensity andheat dissipation device is heavy, the time and cost of manufacturing companies tend to increase because it requires secondary process of installation of all the components 5 together such as gluing, cleaning anodizing etc. also the packaging size of the assembly tends to increase.
[010]
Thus, there is a need in the art for providing the lamp assembly thataddresses at least the aforementioned problems.
