Abstract

The invention relates to the technical field of vehicle lighting, and discloses a vehicle LED light source based on ceramic fluorescent piece packaging and a packaging process of the vehicle LED lightsource. The LED light source comprises an aluminum nitride ceramic makeup support which is internally provided with a fixed plate. A positive pin and a negative pin are respectively arranged at the positions, located on the two sides of the fixed plate, of the aluminum nitride ceramic makeup support, and three inverted LED wafers distributed at equal intervals are welded to the top of the aluminum nitride ceramic makeup support through coated scaling powder. According to the invention, inorganic ceramic fluorescent pieces are uniformly and accurately attached to the surfaces of three invertedLED wafers which are connected in series, and then the curing and molding are performed. Moreover, the distance between the wafers is controlled to be less than 120 microns through a reflow solderingeutectic process, so the problems of double images and projection shadows of a multi-wafer light source module are well solved, and the high-reliability vehicle LED light source packaged through theceramic fluorescent pieces has mass production feasibility and can meet the high-reliability requirement of the market.

Description

technical field [0001] The invention relates to the technical field of vehicle lighting, in particular to a vehicle LED light source packaged based on ceramic fluorescent sheets and a packaging process thereof. Background technique [0002] LED light sources are mainly used as lighting electronic components and are widely used in various types of vehicle lighting, such as motorcycle lighting, outdoor flashlight spotlight lighting, off-road SUV lighting, and other mid-to-high-end modified vehicle lighting fields. [0003] Conventional high-power automotive LED light sources are all mounted on the surface of the LED chip with a fluorescent diaphragm made of silica gel. The yellow fluorescent diaphragm produces white light under the excitation of blue LED light. The irradiance has extremely high requirements, that is to say, the luminous flux requirement within the unit luminous angle is extremely strict. In order to meet the light emission requirements of such high irradiance ...
