Description
Technical field
The present invention relates to a kind of LED light source board.
Background technology
LED the most gradually replaces existing electric filament lamp, fluorescent lamp becomes the luminaire that a new generation lives, existing
LED light source board includes PCB substrate, the LED chip being separately fixed in PCB substrate and copper plate, the most equal
By PCB substrate, LED is electrically connected portion and heat radiation, so there is electric energy and heat is all carried out by PCB substrate, heat radiation
Weak effect, makes reduce the service life of PCB substrate, thus reduces the service life of LED, and Practical Performance is poor, improves life
Cost alive.
Summary of the invention
It is poor that the technical problem to be solved in the present invention is that existing LED light source board exists radiating effect, and service life is low, from
And a kind of LED light source board is provided.
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions:
A kind of LED light source board, the LED chip including PCB substrate, being fixed on PCB substrate upper surface and be fixed on PCB
The copper plate of upper surface of base plate, described PCB substrate is provided with one layer of insulating barrier being easy to copper plate protection, in described PCB substrate
It is fixed with the dimming components of the light source that regulation LED chip produces.
Preferably, described dimming components includes silicone grease layer, the luminescent layer being coated on silicone grease layer, and described silicone grease layer is with luminous
The thickness of layer ratio for 3:1～5:2, is coated on silicone grease layer by luminescent layer, is conducive to regulating LED chip light source, adapt to
Different workplaces, using effect is good, easy to process.
Preferably, the thickness of described dimming components is 3mm～4mm, beneficially LED chip light source regulation, works as dimming components
Thickness less than 3mm time, be unfavorable for that dimming components is fixed, the service life of dimming components is poor, when dimming components thickness be more than 4mm
Time, the weak effect of dimming components regulation, poor reliability.
Preferably, described PCB substrate is provided with the cavity volume being fixed in PCB substrate by dimming components, and it is easy to process, even
Connecing reliable, regulating effect is good, and serviceability is good.
Preferably, the horizontal line at described dimming components upper surface place is less than the horizontal line at cavity volume upper surface place, effectively
Avoid coming off of dimming components, service life is long, and unfailing performance is good.
Preferably, the thickness of described insulating barrier is 1.5mm～2.5mm, when thickness of insulating layer is less than 1.5mm, and insulating barrier
Broken, when thickness of insulating layer is more than 2.5mm, it is unfavorable for that copper plate is fixed.
Beneficial effect:
Copper plate is fixed in PCB substrate by the present invention by insulating barrier, makes LED ensure that LED chip in use
Electrical connection section with heat radiation separate on substrate, improve the heat dispersion of PCB substrate, effectively raise service life,
And the light source produced LED chip by dimming components is adjusted, convenient and practical.
