Problems solved by technology

[0008] 1) The lack of near-ultraviolet bands leads to the lack of ultraviolet light excitation for road signs containing fluorescent media (the excited wavelength of the fluorescent media is <400nm), which reduces the extra brightness of the fluorescent media by nearly twice, reducing the nighttime road traffic. The clarity of the signboard being seen by the driver reduces the visual distance of the road signboard and reduces driving safety
[0009] 2) At the same time, due to the lack of power distribution of multi-segment light waves, such as cyan and red, the color reproduction of the illuminated object is inferior, which weakens the driver's correct judgment of pedestrians, terrain, and objects on the road
[0010] 3. In addition, the life of the current car lights is greatly affected by heat. How to quickly diffuse the heat of the illuminant wafer of the light source is also a problem that needs to be considered

Abstract

The invention provides a vehicle lamp light source device and a vehicle lamp module. The vehicle lamp light source device comprises one or a plurality of light-emitting wafers and a base for mountingthe wafers; the wafers are packaged on the base by a fluorescent powder silica gel layer; the wafers are NUV (Near Ultraviolet) gallium nitride LED (Light-Emitting Diode) wafers with a light-emittingwavelength range of 380nm to 420nm, and light finally output to the outside is near natural light; the base is a substrate of a PLCC / ceramic bracket or COB integrated light source; and the wafers forma single connection, parallel connection, serial connection or series-parallel connection mounting mode on the base. According to the invention, by using NUV gallium nitride LEDs as light sources, problems of NUV loss and color distortion which are caused by adoption of an LED blue light wafer in the prior art are solved; and by a proportion of the fluorescent powder silica gel layer, the light finally output to the outside becomes the near natural light similar with the sunlight, so that the field of vision of a driver is greatly changed, and a safe viewing distance is improved. Moreover, the near natural light does not contain strong blue white light which can instantaneously make people blind, and thus, the vehicle lamp light source device has a higher safety coefficient than a HID (High intensity Discharge) head lamp.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a car light source device capable of improving ultraviolet light excitation and enhancing color reproduction, and a car light module using the car light source device. Background technique [0002] The current light source of headlights mainly adopts white light source of halogen lamp, xenon lamp, laser lamp or LED blue light (420nm-470nm) wafer. [0003] Halogen lamp is an improved version of ordinary incandescent lamp. Its bulb cavity is filled with halogen gas such as iodine and bromine, which replaces the vacuum of incandescent lamp. Black, so that the filament can withstand higher temperature and produce more light. However, the light of the halogen lamp is yellowish, the brightness is low, the power consumption is large, the irradiation distance is limited, and the mold of the lamp is large, and the service life is only a few hundred hours. [0004] Xenon lamp (HID): It is a ki...
