Description

Lighting structure

A lighting structure, in particular a lighting structure which can be applied to vehicles.

When driving vehicles (such as buses, cars, motorcycles), driving in specific environments (such as tunnels, nights, fog, rain, etc.), there is often a problem of poor sight and affecting driving safety. Therefore, vehicles need to be equipped with lights to deal with the above situation. Existing lamps are divided into halogen, xenon, and light-emitting diode (LED) types. Among them, LED lamps are longer than other types of lamps in terms of service life, lighting brightness, and lighting speed. Excellent, therefore, the application of LED lighting has become the consensus of various car manufacturers.

However, in general, only about 20% of the input power of LED products will be converted into light energy, and the remaining about 80% will be converted into thermal energy. If the thermal energy generated by LED light cannot be exported, it will cause the The surface temperature (Junction Temperature, Tj) is too high, which affects the life cycle, luminous efficiency and stability of LED products. Therefore, the heat dissipation design of LED lamps has become a very important issue.

The most commonly used method of heat dissipation design of LED lamps is to set a cooling fan and heat dissipation fins on the LED lamps. When the LED emits heat energy, the heat energy is first transferred to the heat dissipation fins by heat conduction. Then, the heat is quickly taken away by the fan through thermal convection. Generally, the cooling fan can quickly achieve the cooling effect, but additional power is required for use. Source, and there are reliability issues such as noise and vibration.

In addition, general vehicle headlights usually have a high-beam and low-beam switching design. The conventional near-beam switching design uses a solenoid valve to drive the shading plate. In detail, the near-beam switching module is set to emit light. Between the element and the lens used to refract the light source, the near and far light switching module includes at least a fixing plate, a light shielding plate, a pull piece, a solenoid valve, a valve seat, a valve stem, a spring, etc. The fixing plate is used to fix the valve seat and the like On the lamp holder, a solenoid valve is arranged in the valve seat. The valve rod connects the solenoid valve and the pull piece, and a spring is sleeved. When the solenoid valve is powered, the solenoid valve stem telescopically moves the pull piece to pull down to drive the shading plate. The deflection affects the projection range of the light source to form the operation of switching between near and far lights. However, from the above, it can be known that the conventional far-near light switching module has many constituent elements, which is time-consuming to assemble, and the use of solenoid valves requires additional power supply. Furthermore, a large amount of heat is also generated when the far-near light switching operation is performed. This adds a burden to the design of the overall light scattering.
