Problems solved by technology

However, the ballasts of general energy-saving light bulbs and energy-saving lamp tubes are fixed. If the old ones are to be replaced with new ones, the ballasts must be discarded together. After coating, it will still inevitably cause serious pollution to the environment after being discarded

Abstract

The invention relates to a mixed light type light emitting diode packaging structure capable of increasing color rendering and brightness, comprising a base plate unit, a light emitting unit, a frame unit and a packaging unit, wherein the light emitting unit comprises a first light emitting module and a second light emitting module, wherein the first light emitting module is used for producing first color temperature, and the second light emitting module is used for producing second color temperature; the frame unit comprises two surrounded frame colloids which are surrounded on the upper surface of the base plate unit by a coating mode, and the two surrounded frame colloids respectively surround the first light emitting module and the second light emitting module to respectively form two colloid limiting spaces positioned above the base plate unit; and the packaging unit comprises a first light transmission packaging colloid and a second light transmission packaging colloid which are formed on the upper surface of the base plate unit to respectively cover the first light emitting module and the second light emitting module, and the first light transmission packaging colloid and the second light transmission packaging colloid are respectively limited into the two colloid limiting spaces. In the invention, light emitting diodes capable of generating high color temperature are connected with light emitting diodes capable of generating low color temperature in series or in parallel to form the mixed light type light emitting diode packaging structure capable of increasing color rendering and brightness.

Description

technical field [0001] The invention relates to a light-mixing type light-emitting diode packaging structure, in particular to a light-mixing type light-emitting diode packaging structure capable of improving color rendering and brightness. Background technique [0002] The invention of electric light can be said to have completely changed the way of life of all human beings. If we live without electric light, all work will stop at night or when the weather is bad; The way of construction or the way of life of human beings will be completely changed, and all human beings will not be able to progress because of this, and will continue to stay in a relatively backward age. [0003] Therefore, the lighting equipment used in the market today, such as fluorescent lamps, tungsten filament lamps, and even the energy-saving light bulbs that are widely accepted by the public, have been widely used in daily life. However, most of these lamps have disadvantages such as fast light deca...
