Description
技术领域technical field
本发明属于LED光源技术领域，具体涉及一种新型LED车用光源。The invention belongs to the technical field of LED light sources, and in particular relates to a novel LED light source for vehicles.
背景技术Background technique
灯泡光源的车灯，受到造型、空间、点亮外观、使用寿命、汽车节能减排等方面的要求，已经逐步被LED光源所取代。LED光源具有色温范围可调节空间大、能耗小、体积小、耐温性好、工作时间长的特性。随着近几年光伏产业的发展，LED光源的成本越来越低。Car lights with bulb light sources have been gradually replaced by LED light sources due to the requirements of shape, space, lighting appearance, service life, and automotive energy saving and emission reduction. LED light source has the characteristics of large adjustable space for color temperature range, low energy consumption, small size, good temperature resistance and long working time. With the development of the photovoltaic industry in recent years, the cost of LED light sources is getting lower and lower.
目前主机厂在车辆设计的时候，会考虑汽车的灯具造型，灯具偏向于狭长型，灯具的造型、能耗以及后期沿用的可能性，都成为主机厂是否采用该设计的主要考虑因素。因此，灯厂研制开发出小功率，高光效，小造型，能被其他车型沿用等优点的LED光源模块很有必要。At present, OEMs will consider the shape of lamps and lanterns when designing vehicles. Lamps tend to be narrow and long. The shape, energy consumption and possibility of future use of lamps have become the main considerations for OEMs whether to adopt this design. Therefore, it is necessary for the lamp factory to develop LED light source modules with advantages such as low power, high luminous efficiency, small shape, and can be used by other models.
LED是一种可以发光的二极管，它只能单向导电，其输出的光强与通过的电流成正比。大电流的输入会导致LED比较大的光衰，若不赶快将热量散出，最直接的就是影响LED的亮度及使用寿命，甚至损坏。由此可以看出LED的发光强度受到热量的影响比较大。因此LED光源模块的设计中，要满足能耗小、体积小的特点，对其散热器的要求就比较高。LED is a kind of diode that can emit light. It can only conduct electricity in one direction, and its output light intensity is proportional to the current passing through it. The input of high current will lead to a relatively large light decay of the LED. If the heat is not dissipated quickly, the brightness and service life of the LED will be affected most directly, or even damaged. It can be seen that the luminous intensity of LED is greatly affected by heat. Therefore, in the design of the LED light source module, to meet the characteristics of low energy consumption and small size, the requirements for the radiator are relatively high.
中国实用新型专利“一种汽车用LED后雾灯”(申请号：CN201520145541.3，授权公告号：CN20446011U)，公开了一种汽车用LED后雾灯，包含配光镜、灯壳、反光碗、基板、线路板、至少一个LED芯片、恒流电源芯片和散热部件。其LED是依靠恒流电源芯片进行驱动，价格昂贵。散热部件是分离式结构，多个散热体需要单独固定在散热底板上。线路板上有多块基板，需要分别安装固定，导致LED与基板及配光镜之间含有累积误差严重，定位精度差。LED散热依次通过基板、线路板、散热底板和散热体进行，基板、线路板、散热底板、散热体的结合缝隙处含有热的不良导体空气，会导致LED散热效果差。该专利存在结构复杂，造价昂贵，安装繁琐，散热效果差的问题，不便于大批量推广。Chinese utility model patent "A LED rear fog lamp for automobiles" (application number: CN201520145541.3, authorized announcement number: CN20446011U), discloses an LED rear fog lamp for automobiles, including a light distribution mirror, a lamp housing, and a reflective bowl , a substrate, a circuit board, at least one LED chip, a constant current power supply chip and a heat dissipation component. Its LED is driven by a constant current power supply chip, which is expensive. The heat dissipation component is a separate structure, and multiple heat sinks need to be separately fixed on the heat dissipation bottom plate. There are multiple substrates on the circuit board, which need to be installed and fixed separately, resulting in serious cumulative errors between the LED, the substrate and the light distribution mirror, and poor positioning accuracy. The heat dissipation of the LED is carried out sequentially through the substrate, the circuit board, the heat dissipation bottom plate and the heat sink. The bonding gap between the substrate, the circuit board, the heat dissipation bottom plate and the heat sink contains hot bad conductor air, which will lead to poor heat dissipation effect of the LED. This patent has the problems of complex structure, high cost, cumbersome installation, and poor heat dissipation effect, which is not convenient for mass promotion.

With this setting, the thermal conductivity of the traditional cast aluminum material is 96W/m.k, and the structure in which the cooling column is separated from the radiator body has air between them, so the thermal conductivity is less than 96W/m.k. At the same time, the process of casting aluminum is usually accompanied by heating and casting of aluminum, which consumes a lot of energy and emits a lot of noise during the manufacturing process. The heat sink manufactured by advanced industrial pure aluminum (Al content>99%) cold extrusion molding process has a thermal conductivity of 226W/m.k. The heat dissipation effect is good and the production cost is low, the production process is environmentally friendly, and the assembly process is operable.
