Abstract

The utility model discloses an LED (light-emitting diode) automotive lamp which comprises a base plate, an LED light source arranged on the base plate, a driving circuit and a lamp cover, as well as a control unit for controlling the luminance of the LED light source, wherein the control unit is connected with the driving circuit. The control unit comprises a pulse width modulation controller. The magnitude of current flowing through the LED light source is changed through the pulse width modulation controller, and the luminance of the LED light source is changed along with the change of the magnitude of current flowing through the LED light source, so that the luminance of the LED automotive lamp is adjustable, and different requirements of people on luminance during the automotive lamp using process can be met.

Description

The LED auto lamp
Technical field
The utility model relates to a kind of automotive lighting and uses light fixture, particularly a kind of LED auto lamp.
Background technology
Auto lamp is for guaranteeing that safe driving is installed in the various traffic lights on the automobile; It is the vitals in the automobile production, although compare engine or electric control system, its technology content is relatively low; But its effect can't neglect, the effect that has illumination and transmit signal.Yet the brightness of general auto lamp can not be transferred, and has satisfied not the demands of people to brightness when when people play outside, using the auto lamp illumination.
Therefore, how addressing the above problem is the technical problem that needs to be resolved hurrily in the industry.
Summary of the invention
The main purpose of the utility model provides a kind of LED auto lamp, is intended to be implemented under the condition of the basic function with LED auto lamp, also has the brightness of scalable LED auto lamp, satisfies people's different demands to brightness when using the auto lamp illumination.
The utility model proposes a kind of LED auto lamp, comprises substrate, is arranged on led light source, drive circuit and lampshade on the said substrate, comprises that also one is used to control the control module of said led light source brightness, and said control module is connected with said drive circuit.
Preferably, said control module comprises PDM keyer.
Preferably, said control module comprises fading unit.
Preferably, said PDM keyer is connected with external power source, said drive circuit respectively.
The utility model changes the size of current of the led light source of flowing through through PDM keyer; The size of current of led light source of flowing through changes; The brightness of led light source changes thereupon; Make the brightness of LED auto lamp have controllability, satisfy people's different demands to brightness when using the auto lamp illumination.The utility model also can be regulated the power of led light source through fading unit, and the power of led light source changes, and the brightness of led light source changes thereupon.
Description of drawings
Fig. 1 is the stereogram of an embodiment of the utility model LED auto lamp;
Fig. 2 is the structured flowchart of an embodiment of the utility model LED auto lamp.
The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
With reference to Fig. 1; One embodiment of the LED auto lamp of the utility model is proposed; Comprise lamp socket 200, be arranged on substrate on the lamp socket 200, be arranged on led light source 30 on the said substrate, led drive circuit 301 that is connected with led light source 30 and the lampshade 100 that is connected with lamp socket 200; Comprise that also one is used to control the control module of said led light source 30 brightness, said control module is connected with said led drive circuit 301.Said control module comprises PDM keyer 20.Said PDM keyer 20 is connected with power supply 10, led drive circuit 301 respectively.Change the size of current of the led light source 30 of flowing through through PDM keyer 20; The size of current of led light source 30 of flowing through changes; The brightness of led light source 30 changes thereupon; Make the brightness of LED auto lamp have controllability, satisfy people's different demands to brightness when using the auto lamp illumination.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
