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 illuminating device. After the illuminating device irradiates any wavelength conversion region with laser light, the received light is emitted in a predetermined direction through the reflection of the corresponding reflector. Due to the high brightness of the laser light source, the illumination device is guaranteed The light output brightness is high; and the structure of the lighting device is simple, and the volume of each component is limited, which ensures that the volume of the lighting device is small; through the semi-closed fixing method of each reflector and the first substrate, it is guaranteed that the affected All the laser light is emitted to avoid the waste of light; the wavelength conversion device is controlled by the control device to switch different wavelength conversion regions to receive the laser light, so as to achieve different light output effects of the lighting device, and at the same time optimize the reflection of the wavelength conversion device. The difference in parameters such as the light spot of the transmitted second laser light further realizes different light output effects of the lighting device, thereby improving the applicability and flexibility of the lighting device.

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...
