Description

Lamp device and its shutter structure

The present invention relates to a lamp device, and more particularly to a lamp device having a state of switching a near-light lamp and a shutter structure thereof.

First of all, in the design of the existing lamp device, the requirements and specifications of the high beam and low beam are different. The high beam requires concentrating to achieve long-distance illumination, while the low beam requires expansion. In order to achieve a broad vision in the close range. Therefore, in the design concept of the lamp device, the high beam and the low beam are usually designed separately, that is, each has its own lamp cup to be responsible for the illumination of the high beam and the low beam respectively. For example, Taiwan Patent Publication No. M353845 "Lighting Structure for Driving Illumination" uses separate light and high beam modules to achieve the switching function of the near and far lights.

Then, the light-emitting module of the existing lamp device can be divided into a tungsten halogen lamp and a HID lamp (High Intensity Discharge Lamp), wherein the tungsten halogen lamp has an arc length of 5.6 mm (millimeter, mm), and the HID lamp The arc length is 4.3 mm, and most of its light collection systems use PES (Projector Ellipsoid System). The main illumination type of the HID lamp is concentrated at the two electrodes. Therefore, the concentrating light of the high beam can be distributed by the light spot near the high intensity, and the low beam can be made by the arc away from the high light intensity. Light distribution. However, since the light-emitting form of a light-emitting diode (LED) is a uniform surface light source and there is no particularly high-intensity region, it is also difficult to design a near-integrated vehicle under the structure of a single lens. Light device. In addition, if the existing lamp device is to design a vehicle lamp device that is far and near in a single lens structure, the overall volume will be large, and the luminous intensity can only meet the regulations. Fan's threshold.

Then, in order to simulate the arc length and size of the tungsten halogen filament and the HID lamp, the existing LED module for the vehicle headlamp adopts a continuous crystal-connected LED package, and Since only a single light-emitting module can be used in the case of a single optical axis and a single focus, most of the current light-emitting diodes of 1 mm * 1 mm are used as the basis for packaging. The continuous continuous-crystal light-emitting diode package refers to a plurality of light-emitting diode chips packaged on a germanium substrate by a eutectic process or other processes, thereby making the die of the light-emitting diode (wafer) , Chip) The distance between each other can be 0.2 mm or less, or even as small as 0.05 mm or less. Since a plurality of light-emitting diodes have a small pitch from each other, they can be regarded as a continuous light-emitting body. However, such a continuous crystal-connected light-emitting diode package has a price of 10 times or more at the same brightness as that of the illumination light-emitting diode manufactured by a general process. That is, the illumination light-emitting diode system packaged in the general process directly encapsulates the die (chip) of a single light-emitting diode, or directly performs the grain of two or more light-emitting diodes. Package. In other words, a package using such a light-emitting diode is a non-connected structure. Furthermore, the light-emitting diode encapsulated by the non-crystallized state means that the distance between the crystal grains of each of the light-emitting diodes is greater than 0.2 mm or 0.5 mm, even for each of the light-emitting diodes. The distance between the grains can be up to 4 mm.

In addition, the existing lamp device usually only illuminates the light-emitting structure located above the optical axis of the lens in the near-light state, and the light-emitting structure located below the optical axis of the lens is illuminated in the state of the high-light state (when the shutter structure is turned down). However, this method cannot effectively utilize the light-emitting structure.

Therefore, how to provide a light-emitting diode as an illumination source, and to achieve the switching function of the near lamp and the remote lamp under a single lens, and at the same time utilize the arrangement relationship between the shutter structure and the lamp device to overcome the above defects It has become an important issue that people in the technical field want to solve.
