Description

The LED light source module that a kind of linearity is luminous

Technical field

The utility model relates to a kind of LED light source module, relates in particular to the luminous LED light source module of a kind of linearity.

Background technology

Semiconductor light-emitting-diode (LED) is a kind of semiconductor that can be visible ray by electric energy conversion, it has changed the luminous principle luminous with the electricity-saving lamp tricolor powder of incandescent lamp tungsten filament, and the employing electroluminescence, the characteristics of LED are very obvious, and the life-span is long, light efficiency is high, radiationless and low-power consumption.LED illumination is considered to one of field of tool development prospect of 21 century, and it, also will be for promoting energy-saving and emission-reduction, set up conservation-minded society and make major contribution when causing the illumination revolution.

Traditional multi-chip LED light source module, generally adopt aluminium base, copper base or ceramic substrate, basic own opaque, so after welding the LED light source particle above the light source module, the bright dipping that can only make progress is larger for design, the luminous intensity distribution restriction of light fixture.In addition, traditional multi-chip LED light source module has utilizes aluminium base as the heat sink double circuit board of doing again, need to insulating barrier and circuit be set on surface, not only affects radiating effect but also can strengthen material cost; What have separates heat sink and circuit board, though can improve radiating effect but material cost is still higher, the Chinese patent application " LED light source module " that is CN102738375A as publication number discloses a kind of LED light source module, comprise a heat-radiating substrate, a conductive and heat-conductive layer, at least one LED chip, reach a plastic-sealed body, described conductive and heat-conductive layer is coated on heat-radiating substrate, described plastic-sealed body is by described LED chip plastic packaging on the conductive and heat-conductive layer, and described heat-radiating substrate is aluminium base.

Take bulb lamp as example, when opaque substrate module is directly used in lamp, can only reach the effect of half luminous intensity distribution type (beam angle is less than 180 degree) bulb lamp; Want to realize that (beam angle is greater than 180 degree for the full luminous intensity distribution of standard (beam angle is greater than 180 degree) in national and foreign standards and full luminous intensity distribution type, and the luminous flux in 135～180 degree zones be not less than total light flux 5%) requirement, just must increase secondary optical lens in light fixture, increase the cost of light fixture.The Chinese patent that is CN202403005U as publication number discloses a kind of full light-distribution LED bulb lamp, described bulb lamp comprises driving power, substrate, radiator and the reflector of LED light emitting module is installed, described substrate comprises go in ring substrate and dish type substrate, and the substrate that goes in ring is parallel with the dish type substrate and be arranged on one heart on described radiator.This patent just needs polylith substrate and reflector, has obviously increased manufacturing cost.

The utility model content

The utility model provides a kind of linearity luminous LED light source module, and its preparation is simple, low cost of manufacture and can also guarantee larger lighting angle.
