Embodiment 1

[0024] like Figure 1a As shown, this embodiment provides an LED automotive lighting fixture, the LED automotive lighting fixture includes a light emitting unit 101 and a control unit 104, the control unit 104 is used to control the light emitting unit 101, so that the light emitting unit 101 Realize lighting, flashing, brightening, darkening and other display effects.

[0025] Each light-emitting unit 101 can be fixed on the fixed substrate 103, and the fixing basically plays a role of installing and fixing each LED light-emitting unit. Each light emitting unit 101 includes an LED unit and a package body. The LED unit includes four or more LED thin film chips 102 . The shape and size of each LED thin film chip can be the same or different. For example, each light emitting unit includes four LED thin film chips with different shapes and sizes; or, each light emitting unit includes four LED thin film chips with the same shape and different sizes; or, each light emitting unit in...

Embodiment 2

[0032] like Figure 2a As shown, on the basis of the above examples, in the LED automotive lighting fixture provided in this embodiment, the centers of gravity or geometric centers of all LED thin film chips are located on the same plane, for example, the centers of gravity of all LED thin film chips are located on the same plane ; For another example, the geometric centers of all LED thin film chips are located on the same plane. Or, on the basis of the above examples, in the LED automotive lighting fixture provided in this embodiment, except for one LED thin film chip X, the centers of gravity or geometric centers of the other LED thin film chips are located on the same plane A; In another example, the LED thin film chip X is parallel or substantially parallel to the plane A, or the light-emitting surface or cross section of the LED thin film chip X is parallel or substantially parallel to the plane A.

[0033] For example, the LED unit includes LED thin film chip 201, LED ...

Embodiment 3

[0037] like image 3 As shown, on the basis of the above examples, the LED automotive lighting module provided in this embodiment also includes a PCB board 301, and electronic circuits, such as power supply lines and signal lines, are printed on the PCB board. The above-mentioned PCB board can replace the fixed substrate in Embodiment 1, and play the role of installing and fixing each light emitting unit 101 .

[0038] Moreover, grooves 302 are provided on the PCB, and each light-emitting unit is correspondingly fixed in the groove 302, that is, each light-emitting unit is correspondingly fixed in a groove 302, and is compatible with the circuit on the PCB. Electrical connection and signal connection; that is, each light emitting unit can be positioned and fixed through the groove 302 .

[0039] In addition, each groove 302 is further provided with a light-gathering portion, and the light-gathering portion is fixedly arranged around the periphery of each light-emitting unit. ...

Abstract

The invention discloses a light emitting diode (LED) automobile lighting lamp, comprising lighting units and a control unit. Each lighting unit comprises an LED unit and a package body, wherein the LED unit comprises at least four LED thin film chips which are mutually and partially overlapped to form a hollow polyhedron. The control unit comprises a control subunit and at least one temperature detection subunit, wherein the control subunit is used for receiving control signals as well as driving and controlling the lighting units, and the temperature detection subunit is used for detecting the interior temperature of the LED automobile lighting lamp. The control unit sends the control signals to the control subunit according to the interior temperature. The LED automobile lighting lamp has high brightness and low power consumption and can perform control according to the interior temperature, thereby the service life of the LED automobile lighting lamp is effectively prolonged.

Description

technical field [0001] The present invention relates to an LED lighting device, in particular to an LED automotive lighting fixture. Background technique [0002] Automotive LEDs can be divided into exterior and interior uses. The interior includes dashboard, air conditioner, audio and other indicator lights and internal reading lights; the exterior uses include third brake lights, tail lights, direction lights, side lights, etc. There is no doubt that the use of high-brightness LED lighting will be the main feature of future cars, thanks to the many basic advantages that LEDs have over traditional incandescent lighting solutions. In addition, the use of LED lighting can also drive changes in automotive design technology and design style. The key problem faced by users who use high-brightness LEDs is the self-heating problem of LEDs. High-brightness LEDs have relatively high power, and the interior of LED lamps The accumulated heat can easily burn out the components. [00...
