Detailed Description
In order that the present invention may be more clearly understood, the following detailed description is given with reference to the accompanying drawings.
The first embodiment is as follows:
as shown in fig. 1-2, in the present embodiment, an LED module lamp structure for a vehicle is provided, which is generally installed inside a lamp to emit light. It mainly comprises LED module 1, thick wall light guide body 2 and support 3, and thick wall light guide body 2 is formed by transparent PC or PMMA material processing. Wherein LED module 1 and thick wall light conductor 2 assemble on support 3, and thick wall light conductor 2 is provided with spotlight ware 21 on being close to LED module 1 one side, preferred spotlight ware 21 and thick wall light conductor 2 formula structure as an organic whole. The thick-wall light guide body 2 has a reflecting surface 22 and a light transmitting surface 23 at both ends, and in order to improve the uniformity of light emission, the surfaces of the reflecting surface 22 and the light transmitting surface 23 are provided with patterns, and the surface of the reflecting surface 22 is plated with an aluminum coating to improve the reflecting effect.
Because the existing multifunctional lamp structure generally selects a plurality of monochromatic LEDs with different light colors to be placed together, the actual light-emitting centers of the LEDs are still slightly uneven from the focal position of the condenser, and some LEDs are seriously out of focus, so that the integral lighting uniformity is not good. To solve this problem and meet the high standard requirements of customers, the present embodiment is designed as such. The LED module 1 specifically comprises a circuit board 11 and a plurality of LEDs 12, and the plurality of LEDs 12 are uniformly arranged on the circuit board 11, specifically referring to the arrangement in a row shown in fig. 2. The LED12 has at least two dies with different light colors, and the LED12 can emit at least two different light colors, that is, the LED adopts a light emitting diode with more than two colors, and the light emitting diode has at least two dies with different light colors, and each die can emit light independently, or a plurality of dies can emit light simultaneously to mix into other light colors, or a plurality of dies can emit light at intervals. The advantage of using such an LED12 is that the distance from the LED light-emitting center to the focal point of the condenser 21 can be effectively reduced, thereby making the emitted light more uniform. The plurality of LEDs 12 in this embodiment are arranged on the focal position line of the condenser 21, and certainly, the overall geometric center of the LEDs 12 may be placed at the focal point of the condenser 21, and the light-emitting center of the die in each LED12 may also be placed at the focal point of the condenser 21, and the final effect will not be affected because the difference between the two methods is small.
In addition, in order to ensure the uniformity of the final light emission lighting, the distance L1 between two adjacent LEDs 12 is ensured to be in the range of 0.5mm-20 mm. For example, L1 in this embodiment is 20mm.
In this embodiment, each LED12 emits light as a light source during light emission, and the emitted light flux can be emitted to the reflection surface 22 of the thick-walled light guide 2 through the condenser 21, reflected by the reflection surface 22, propagated inside the thick-walled light guide 2 to the light transmission surface 23, and finally emitted through the light transmission surface 23. By adopting the design, compared with the combination of a plurality of original monochromatic LEDs, the distance from the LED light-emitting center to the focus of the condenser can be effectively reduced, so that the light emitted from the light-transmitting surface 23 is more uniform, and the whole light-emitting surface of the multifunctional lamp seems to have a more uniform lighting effect, thereby meeting the high standard requirements of customers.
Specifically, the dies in each LED12 in the present embodiment are two, which are the first die 121 and the second die 122 with different light colors, respectively. The first die 121 is blue light, and when the first die 121 emits light alone, the first die is the light for automatic driving, and the second die 122 is yellow light, and when the second die 122 emits light alone, the second die is the light for the turn signal.
Example two:
as shown in fig. 3 and 4, the second embodiment is another modified structure, which retains most of the features of the first embodiment, so that the basic principles and advantages are consistent. The difference is that the second embodiment adopts a light guide structure, the shape, configuration and position layout of the LED module 1, the thick-wall light guide body 2 and the support 3 are different, especially the arrangement manner of the LEDs 12 is different, as can be seen from fig. 3, the four LEDs 12 are arranged closely in two rows and two columns, of course, the first die 121 and the second die 122 are transversely or vertically arranged without influence, and the distance L1 between two adjacent LEDs 12 is 1mm. The light emitting principle and the embodiments of the second embodiment are consistent, and are not described herein again.
In the description of the present specification, reference to the description of "one embodiment," "an example," "a specific example," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
