Abstract

The invention provides an all-inorganic LED lamp and a packaging method thereof. The all-inorganic LED lamp comprises a base and an LED chip; the base is provided with a bowl; the LED chip is arrangedinside the bowl and electrically connected with the base; a glass cover plate for sealing the LED chip is arranged on the bowl; and the surface of the bowl is coated with a solder, and the glass cover is bonded to the bowl through the solder. According to the all-inorganic LED lamp provided by the invention, the glass cover plate and the bowl are bonded together through the solder, so that the application of organic materials such as silica gel can be avoided, and the all-inorganic LED lamp can be used for packaging of devices which are not suitable for being packaged by using organic material, and solves the problem that related device packaging materials are easy to age and go bad in a severe environment.

Description

technical field [0001] The invention belongs to the field of LED lighting, and in particular relates to an all-inorganic LED lamp and a packaging method thereof. Background technique [0002] LED has excellent characteristics such as small size, high efficiency, strong applicability, good stability, short response time, long life, and no pollution to the environment, so it is widely used in people's daily life. In recent years, with the improvement of people's living standards Improvement, UV LEDs have the functions of sterilization, anti-counterfeiting, curing, etc., so the application of UV LEDs is becoming more and more extensive. At present, the packaging of LEDs mostly uses organic materials such as silica gel and epoxy resin to seal and protect the LED chips. These materials are light-transmitting Good performance, easy to operate, can increase the amount of light output, and has high requirements for packaging conditions. If the curing temperature is high, the curing ...
