An LED module and an LED light lamp

Abstract

A LED module and an LED light lamp are provided, include a substrate, a plurality of light emitting units on a substrate and an encapsulation cover body encapsulating the plurality of light emitting units, The plurality of light emitting units include: At least one or more ultraviolet light emitting units and at least one or more white light emitting units are formed on the substrate, a groove carrying a white light unit is formed on the substrate, the at least one or more white light emitting units are arranged in the groove, and the at least one or more ultraviolet light emitting units are exposed on the surface of the substrate at a non-groove. As that LED module arrange the ultraviolet light emitting unit on the surface of the substrate and the white light emit unit in the groove structure provided by the substrate, the organic material provided by the ultraviolet light emitting white light unit can be avoid from being directly emitted by the ultraviolet light, and the damage effect of the ultraviolet light on the organic material in the white light unit can be reduced.

Description

technical field [0001] The invention relates to the technical field of light emitting diodes, in particular to an LED module and an LED lighting lamp. Background technique [0002] Light-emitting diode (LED) is a solid-state semiconductor device that can directly convert electricity into light. Because LED does not contain mercury, is small in size, long in life, fast in response, environmentally friendly, energy-saving, and has high color saturation, it makes it It is widely used, especially white light LED, which is considered as the third generation of lighting source after incandescent lamps and fluorescent lamps, and is widely used in liquid crystal projection devices, mobile phone backlights, display screens, etc. [0003] Along with the raising of people's living standard, the application of LED light-emitting device is also more and more popular, in recent years LED light-emitting device has developed from simple functional lighting to multifunctional direction, such...

AI Technical Summary

Problems solved by technology

At present, the LED lighting involved is to arrange a plurality of LED chips in an array on the substrate, and the white light units formed by the multiple LED chips and fluorescent glue are distributed in the LED lighting, and in this multi-LED chip module Directly introduce ultraviolet LED chips. There are a lot of organic materials in the module of this LED chip. When the ultraviolet LED chips are directly implanted into LED lighting lamps, the destructive effect of ultraviolet rays on organic materials has to be considered, which will inevitably lead to the entire The life of LED lighting is short, which is not conducive to the promotion of this kind of lighting to the market
