[0002] At present, the auxiliary light on the internal combustion engine locomotive and electric locomotive is basically vacuum lamp, and the vacuum lamp usually refers to the lighting device with vacuum or inert gas (such as argon and krypton) filled in the bulb, the auxiliary light on the existing locomotive is full-enclosed design, the reflector and the light distribution mirror are integrated, and the inert gas is filled, although the brightness is high, the cost and energy consumption are also high, and the heat release is large, and there is no matching heat dissipation structure, so that the service life is short, at the same time, the locomotive lamp is a vacuum bulb, and the flashing function thereof is realized by the external special flash generator. The lamp is connected to the output end of the flash generator, and the lamp realizes flashing by the intermittent on-off voltage sent by the flash generator, and the structure and circuit are complex, and once the emergency problem occurs, it is difficult to recover in a short time, and the high-efficiency operation requirement of the locomotive cannot be met. CONTENT OF THE UTILITY MODEL

[0003] In order to overcome the above-mentioned defects, the utility model provides an LED locomotive auxiliary light capable of independent flashing.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Combined with appendix Figures 1-3 The LED locomotive auxiliary lighting shown includes a lamp housing 6, an aluminum substrate 1, several LED beads 7, a reflector 4, a heat sink 5, a driver, and tempered glass 3.

[0024] The lamp housing 6 is made of aerospace aluminum through die casting. It is not only hard and lightweight, but also resistant to high temperatures and has fast heat conduction.

[0025] The aluminum substrate 1 is the carrier of the LED bead 7. It is located at the bottom of the lamp housing 6 and is fixed to the lamp housing 6 by bolts. Thermally conductive adhesive is provided between the two. In this way, the aluminum substrate 1 can better transfer the heat of the LED bead 7 to the lamp housing 6, thereby improving the heat dissipation efficiency.

[0026] The aluminum substrate 1 has several LED beads 7. In this design, such as Figure 3 As shown, the LED beads 7 are arranged in a ring on the aluminum substrate 1, and each LED bead is electrically connected in parallel. The ring arrangement of the LED beads 7 disperses them as much as possible across the aluminum substrate 1, ensuring a more even distribution of heat and preventing excessive heat concentration that could lead to poor heat dissipation and burnout. Furthermore, the LED beads 7 are arranged circumferentially along the edge of the aluminum substrate 1, while the center of the aluminum substrate 1 can be positioned according to the actual dimensions. Figure 3 In this design, one LED bead 7 is placed at the center. If the aluminum substrate 1 is smaller, the central LED bead 7 can be omitted. If the size is sufficient, multiple rings of LED beads can be used. This concentrates most of the heat generated at the edge of the aluminum substrate 1. Figure 2 As can be seen, the edge of the aluminum substrate 1 is at the edge of the heat dissipation fin 5. The edge of the heat dissipation fin 5 is the air inlet and outlet, which is more conducive to heat exchange.

[0027] A reflector 4, disposed within the lamp housing, reflects the light emitted by the LED beads 7. The reflector 4 has the same number of reflector cups as the LED beads 7, with a notch at the bottom to accommodate the LED beads 7. Since there are multiple LED beads 7, the overall lamp power can be controlled by adjusting the number of LED beads 7. Furthermore, the LED beads are designed in parallel; if one LED bead 7 fails, the others remain unaffected, ensuring continued operation of the locomotive. Similarly, each LED bead 7 is equipped with a reflector cup, effectively stacking multiple LEDs within a single lamp, ensuring both brightness and intensity, as well as a consistent light range. The reflector is made of aluminum, specifically aerospace-grade aluminum, which guarantees excellent thermal conductivity and prevents deformation at high temperatures, ensuring that the light range remains unchanged even after prolonged use.

[0028] Heat dissipation fins 5 are located on the back of the lamp housing, with thermally conductive adhesive between them to increase heat exchange efficiency. Heat dissipation fins 5 are the most important heat dissipation component of the auxiliary lighting lamp, and are typically made of aluminum or copper. Figure 2 As shown, the heat dissipation fin 5 has an arc-shaped heat dissipation plate, which allows air to enter the heat dissipation fin 5 from various angles, which is more conducive to heat exchange with the air. In addition, the heat dissipation fin 5 extends to the side of the lamp housing, which not only allows for rapid heat exchange with the bottom surface of the lamp housing 6, but also allows for heat exchange through the side of the lamp housing 6, so as to transfer the heat inside the lamp housing 6 in a timely manner and avoid the internal temperature of the lamp housing from becoming too high.

[0029] The driver 2 is located on the surface of the heat sink 5 to facilitate heat dissipation. The driver 2 is connected to the mains power to provide a stable current to the LED 7. The driver 2 also contains a microcontroller. By programming the microcontroller, the flashing function of the LED 7 can be realized.

[0030] To prevent rain and dust, tempered glass 3 is provided on the open side of the lamp housing, and is sealed to the lamp housing with heat-resistant sealant, thus sealing the aluminum substrate 1, lamp beads 7 and reflector 4 in the lamp housing 6.

[0031] This design presents an independently flashing LED locomotive auxiliary light. The entire body is made of aluminum, including an aluminum reflector 4, which effectively transfers the heat generated by the LED beads 7 to the heat dissipation fins 5, thus protecting the LEDs. The LEDs are arranged in a ring on the aluminum substrate 1, concentrating the generated heat at the edge of the substrate, which is then transferred to the edge of the heat dissipation fins 5. The edges of the heat dissipation fins 5 exchange heat effectively with the air, facilitating heat dissipation. The reflector 4 is made of aluminum, and each LED bead is equipped with a reflector cup, which better concentrates the light source, improving brightness and increasing the beam range. The driver 2 behind the LED light source contains a microcontroller, enabling the LED flashing function. This design allows for safe and reliable use on locomotives without increasing costs.

[0032] The parts not detailed above are existing technologies and therefore have not been described in detail.
