Problems solved by technology

However, the chemical structure of silica gel is relatively loose, and it is a hydrophilic substance, so its protective performance is not good. Therefore, sulfide, moisture, or foreign matter in the air may enter the light emitting device 1
If sulfide in the air enters the light-emitting device 1, it will cause blackening of the internal components or silver-plated parts of the circuit, which will affect the luminous efficacy; if water vapor penetrates into the light-emitting device 1, it will cause corrosion of the internal metal parts, and even cause Short-circuit and damage; if foreign matter such as dust enters the light-emitting device 1, it will also reduce the luminous efficacy of the light-emitting device 1

Abstract

A light-emitting device comprises a substrate, at least one light-emitting diode chip, a sealing colloid, a protective sheet and a protective material. The light-emitting diode chip is arranged on the substrate. The light-emitting diode chip is covered by the sealing colloid, which is provided with a top surface and a side surface. The protective sheet is arranged on the top surface of the sealing colloid. The protective material is arranged on the side surface, and is connected with the protective sheet and the substrate. The light-emitting device can prevent moisture or gas from affecting the luminous efficacy of the light-emitting device, and the service life of the light-emitting device is prolonged.

Description

technical field [0001] The present invention relates to a light emitting device, in particular to a light emitting device with a light emitting diode (Light Emitting Diode, LED). Background technique [0002] A light-emitting diode is a light-emitting component made of semiconductor materials. The component has two electrode terminals. A voltage is applied between the terminals, and a very small voltage is passed through. Through the combination of electron holes, the remaining energy can be excited in the form of light. released. [0003] Unlike ordinary incandescent bulbs, LEDs are cold-emitting, with low power consumption, long component life, no warm-up time, and fast response. In addition, it is small in size, resistant to vibration, suitable for mass production, and can be easily made into extremely small or array modules according to application requirements, so it can be widely used in indicators of lighting equipment, information, communication, and consumer electr...
