LED locomotive headlight structure

The utility model provides an LED locomotive headlight, in particular to a structure of an LED locomotive headlight which is energy-saving, has good heat dissipation, increases service life and improves illumination efficiency.

According to the lighting of the vehicle, it is a very necessary equipment. If there is no such equipment, it is equal to the vehicle can not be driven at night. Therefore, the lights are extremely important. However, the lights are divided into various types in the current generation, including the general tradition. Light bulbs, or high-brightness LED light-emitting diodes, can be illuminated, and the LED light source can be divided into two types: projection type and reflection type, which are projected by projection, and the projection type is in front. The convex lens method is adopted as the optical design concept, and the near-light portion is provided with a light shielding film at the center of the reflection and the convex lens, which acts as a cut-off line for the light of the near lamp. In contrast, the reflective head lamp presents the LED with the reflecting surface. The angle reflects the light to meet regulatory requirements.

However, when the above LED lights are used, the following problems and defects are still needed to be improved:

First, only the general lighting function can be exerted. If the vehicle wants to add the front position light (daytime running light), it must be additionally searched for the appropriate position to be attached to the vehicle body, which is very troublesome and unattractive.

Second, the general LED lights have poor heat dissipation effect. When the heat is emitted in a confined space, the heat will only accumulate on the heat-dissipating metal, and the heat and the outside air cannot be transmitted and dispelled by heat diffusion. The life of the lights is reduced.

Third, the general LED headlights are usually switched between two LEDs with different tilt angles. The same reflection surface is used to change the illumination of the near and far lights, so the effect of the illumination is poor.

Therefore, how to solve the above problems and problems in the past, that is, the creators of the new type and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the creators of this new type have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed such energy saving and heat dissipation. A new patent for the structure of LED locomotive headlights that increase the service life and improve the illumination efficiency.

The main purpose of the present invention is that all of the first light-emitting element, the second light-emitting element, and the third light-emitting element use LEDs as light-emitting sources, and thus have excellent energy-saving effects.

A further main object of the present invention is that the second light-emitting element and the third light-emitting element are horizontally disposed, so that when the light is irradiated, the light cup is reflected, and the curved surface having different upper and lower areas is clearly separated, thereby achieving the near-light, The clear effect of the high beam makes it fast and easy to produce. .

The secondary purpose of the new model is: the active soaking function, which transfers heat through the metal lamp housing and the outside cold air to ensure the service life of the headlight.

The main structure of the present invention can achieve the above-mentioned advantages, including a lamp housing, a reflector lamp cup is fixed on one side of the lamp housing, and a heat dissipation module is housed in the lamp housing (the heat dissipation module includes heat dissipation fins and a cooling fan), and the heat dissipation module is disposed between the reflector lamp cup and the inner side wall of the lamp housing, and the heat dissipation module defines a base portion through which the reflector lamp cup is disposed, and at least one side of the base portion is disposed at least a second light-emitting element placed horizontally, and at least one third light-emitting element placed horizontally at the other side, and a first light-emitting element arranged vertically or laterally at a front end of the base; After the novel operation, the opposite vehicle can clearly see the orientation of the user via the first light-emitting element (front light), thereby having the intention of reminding the opposite vehicle, and when the user is switching between the far-light and the near-light During the change between the parts, the part of the light source projected by the second illuminating element is shielded by the hood, which can block the generation of the residual light above the LED, so that the opposite lane personnel are not glaring and dangerous, so that it can only reflect the appropriate Near The light source, and the light source projected by the third illuminating element can be completely reflected, so that the light source that is illuminated is an upward refracting light effect.

Furthermore, the heat generated by the second light-emitting element and the third light-emitting element is transmitted to the heat-dissipating fin by the base of each of the light-emitting elements, and the heat of the heat-dissipating fin is blown to the metal light by the heat-dissipating fan. Increase the heat dissipation area on the inner side wall of the shell to reach the metal lamp Uniform heat dissipation of the shell.

With the above technology, it is possible to break through the problem that the installation of the conventional LED lamp is very troublesome and unsightly, the life of the lamp is reduced, and the effect of the illumination is poor, and the practical progress of the present invention as the above advantages is achieved.

In order to achieve the above objects and effects, the technical means and structure adopted by the present invention are described in detail in the preferred embodiment of the present invention, and the features and functions thereof are as follows.
