Problems solved by technology

But the existing headlight device for vehicles that adopts light-emitting diodes as the light-emitting light source has reached the limit of its luminous brightness. If you want to improve the headlight device for vehicles again, you need to increase the number of light-emitting diodes. The utilization space of the vehicle headlamp device is limited, and the number of light-emitting diodes cannot be increased again

Embodiment Construction

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0046]As stated in the background technology, the luminous brightness of the existing vehicle headlamp devices using light-emitting diodes as the light source has reached the limit. If you want to improve the vehicle headlamp device again, you need to increase the number of light-emitting diodes , but the utilization space of the existing vehicle headlamp device is limited, and the quantity of light-emitting diodes cannot be increased again.

Abstract

The invention discloses an illumination device. Laser light is adopted for irradiating any one wavelength conversion area, obtained stimulated light is reflected by a corresponding reflective cover to be emitted in the set direction, and it is ensured that the emitted light brightness of the illumination device is high due to the fact that a laser light source is high in brightness. Meanwhile, the illumination device is simple in structure, all components of the device are limited in size, and therefore it is ensured that the illumination device is small in size. By means of the semi-airtight fixing way of each reflective cover and a first substrate, it is ensured that simulated light is completely emitted, and light waste is avoided. A control device controls a wavelength conversion device to switch different wavelength conversion areas for receiving laser light, and therefore different light emitting effects of the illumination device are achieved. By optimizing the parameters such as light spots of second simulated light transmitted by the wavelength conversion device and first simulated light reflected by the wavelength conversion device, the different light emitting effects of the illumination device are further achieved, and then applicability and flexibility of the illumination device are improved.

Description

technical field [0001] The present invention relates to the technical field of lighting, and more specifically, to a lighting device. Background technique [0002] The vehicle headlight device is one of the important components of the vehicle, and the brightness of the light emitted by the vehicle headlight device at night is closely related to the safe driving of the driver. With the continuous development of the lighting technology field, in order to improve the brightness of the vehicle headlight device, the existing vehicle headlight device generally uses a light emitting diode (LED, Light Emitting Diode) as the light source. But the existing headlight device for vehicles that adopts light-emitting diodes as the light-emitting light source has reached the limit of its luminous brightness. If you want to improve the headlight device for vehicles again, you need to increase the number of light-emitting diodes, but the existing The available space of the vehicle headlamp d...
