1 Thermal Performance and Light Distribution Improvement of a Lens-Attached LED Fog Lamp for Passenger Cars W. S. Sim 1 and Y. L. Lee 2* 1 Department of Mechanical Engineering, Graduate school, Kongju National University, Korea. 2 Department of Mechanical and Automotive Engineering, Kongju National University, Korea. *Corresponding Author Abstract Halogen light sources, which have seen significant developments since the invention of the tungsten filament lamp in 1916, are beginning to be replaced by LED light sources. The purpose of this study was to develop a 10W LED fog lamp that has the same light distribution performance as a halogen fog lamp. Heatsink optimization was carried out to enhance heat dissipation performance, and a light distribution lens was introduced to improve light distribution. The analysis showed that the 16 board-fin type heatsink had the best heat dissipation performance. In addition, the lens-attached LED fog lamp exhibited a similar light distribution performance to that of a halogen fog lamp. Keywords: Fog lamp, light distribution lens, light emitting diode, heatsink, junction temperature INTRODUCTION Halogen, the most widely used light source in automobiles, relies on light emitted during thermal radiation by the tungsten filament when the current passes through a lamp filled with halogen and a noble gas. Halogen lamps involve a simple mechanism and produce natural-looking light, but 95% of energy is released as heat and only the remaining 5% is converted into light. While luminous efficiency and color temperature increase with heat, the filament continues to evaporate and eventually breaks [1].As such, the disadvantages of halogen include poor efficiency and a short lifespan. If fog lamps are produced with LED as a light source, the small size of the LED chip will allow a 60 to 75% size reduction compared to halogen fog lamps. Differentiated designs are also possible through multi-chip modules [2]. LED lamps have a lifespan 100 times longer than halogen lamps due to their smaller energy consumption [3]. Their fuel consumption decreases by 19.5% when driving with lights on, and CO 2 emissions are lowered by 19.6% [4]. In 2007, Toyota and Lexus became the first cars to use LEDs in low beam headlights [5]. Recently, Europe has attempted to replace LED with halogen as a light source for not only headlamps, but also fog lamps. In line with this trend, research on LED fog lamps has become popular in Korea. Recent developments in automotive lighting technology have led to high brightness, low power, and high efficiency, as well as the acquisition of characteristics suited to the lighting device. While the aforementioned advantages can be achieved by replacing halogen with LED fog lamps, LED converts more than 60 to 70% of input power into heat, and the junction temperature increases with power supply [6].This increase in junction temperature is known to be a cause of reduced optical power. Chip failure also occurs when the junction temperature exceeds 150, thus severely shortening the LED lifespan [7]. Many studies have been conducted to improve the heat dissipation performance of LEDs. Sökmena et al. [8] optimized the heat dissipation performance of a cylindrical fin type heatsink at various temperatures. Kim et al. [9] applied copper oxide (CuO) to an aluminum-alloy heatsink to improve the heat dissipation performance by enhancing thermal radiation emission. Wang et al. [10] improved the heat dissipation performance of LED headlamps through the heat dissipation analysis of a heatsink combined with heat pipes. Figure 1 shows the light distribution patterns of a halogen fog lamp and a regular LED fog lamp. Since the light distribution pattern of LED fog lamps are easily distinguished from that of halogen fog lamps, it is not possible to achieve the same light distribution as the latter without introducing a light distribution lens. The light distribution of light from the LED lamp has a large area, causes glare in drivers eyes, and has poor intensity in certain areas. In order to use LED fog lamps, such issues must be resolved. This study seeks to develop a 10W LED fog lamp that has the same light distribution performance as a halogen fog lamp. Heatsink optimization was carried out to enhance the heat dissipation performance, and a light distribution lens was introduced to improve the light distribution. Heat dissipation analysis was performed to optimize junction temperatures for various heatsink shapes, and light distribution analysis was used to improve the shape of the light distribution lens and reflector.

Figure 2 shows the schematic diagram of the three heatsinks used to enhance heat dissipation performance. The three shapes used were the circular-fin type, cross-fin type, and board-fin type, and they each had a heat dissipation area of m 2. The flow was steady-state, three-dimensional, and laminar, and thermal radiation was considered in the heat dissipation analysis. Catia[11] was used for the geometric modeling of the LED fog lamp, while Fluent [12] was employed for the heat dissipation analysis. The heatsink shape with the most outstanding heat dissipation was determined through heat dissipation analysis before optimizing the number of fins. To attain the same light distribution performance as a halogen fog lamp, this study introduced a light distribution lens, as shown in Figure 3. The condensing section at the bottom collects light, and the reflecting section at the top has been treated with Ag non-reflective coating. The material of the light distribution lens was assumed to be polycarbonate. Light distribution analysis was performed on the LED fog lamp equipped with the reflector [13] shown in Figure 4.

The results for all three shapes fell below the limit of 120 o C, and the board-fin type had the most 8669

3 outstanding heat dissipation, followed by the circular-fin type and cross-fin type. The board-fin type is not only the most efficient in heat dissipation, but can also be easily mass produced using serration techniques. For these reasons, the board-fin type heatsink was selected for the purpose of this study. Figure 6 shows changes in junction temperature after a light distribution lens is added to the LED fog lamp. The junction temperature of the lens-attached fog lamp rose by 0.3 o C to o C, which can be considered a negligible increase. As such, we can see that the light distribution lens has no significant influence on the heat dissipation performance of the LED fog lamp.

As shown in Figure 7, we can see that the junction temperature of the fog lamp decreases with an increasing number of fins. The junction temperature rapidly declines at first, but the rate of decrease becomes more gradual as the number of fins continues to increase. The most outstanding heat dissipation performance was attained when there were 24 fins. Compared 8670

4 to the case of 16 fins, the area of heat dissipation expanded by 35%, while the junction temperature dropped by 0.3 o C. The weight of the fog lamp at 24 fins was also 10% heavier. Although heat dissipation is better at 24 fins, the 16-fin heatsink is more practical given the weight difference and negligible decrease in junction temperature. Figure 10 shows the irradiance of the halogen fog lamp and LED fog lamp. The results for irradiance are similar to light distribution patterns. When a light distribution lens is attached, the LED fog lamp exhibits a similar irradiance to the halogen fog lamp due to the enhanced light distribution performance. However, the irradiance of the LED fog lamp still has room for improvement. Figure 7: Changes in junction temperature with the number of fins Light distribution analysis of fog lamp with reflector Figure 8 shows the principle of light distribution when light from the fog lamp bounces off the reflector. Light is refracted since it moves sideways instead of going straight due to the light distribution lens, and a suitable light distribution pattern is achieved. Figure 9 shows the light distribution patterns of the halogen fog lamp and the LED fog lamp using the same reflector. The halogen fog lamp has a long and thin pattern suitable for the fog lamp, whereas the LED fog lamp has a pattern concentrated in the center. Compared to the regular LED fog lamp of Figure 3, the lens-attached LED fog lamp has a light distribution performance closer to that of the halogen fog lamp. The light distribution performance is expected to improve further through the use of multi-face LED fog lamps.

Through the analysis, the heat dissipation performance of the 10W LED fog lamp was optimized and the light distribution performance improved. The conclusions derived in this study are as follows: 1. The LED fog lamp with the 16 board-fin type heatsink offers the most outstanding heat dissipation performance. In addition, the board-fin type is suitable for mass production. 2. When a light distribution lens is introduced to improve light distribution performance, the junction temperature remains almost the same, and the heat dissipation performance is also satisfactory. Here, the junction temperature is approximately 10.8 o C lower than the limiting temperature. 3. The lens-attached LED fog lamp showed an improved light distribution performance compared to the regular LED fog lamp. However, to achieve the same light distribution performance as the halogen fog lamp, further improvements such as the use of multi-face LED fog lamps are needed. To enhance light distribution performance, optimization studies can be performed on variables such as the position and number of LED modules and LED chip arrangement.
