Abstract
The LED area light source includes one LED base board with installed LED's; one bracket around the LED's with one outwards opened inner cone type reflector coated with reflecting material; and one fluorescent powder board on the bracket to cover the LED's in some interval. The fluorescent powder board is made of transparent material and has fluorescent powder coated in the side facing the LED's. The LED base board made of heat conducting material is fixed on the casing via heat conducting material. The present invention forms homogeneous light emitting area in the fluorescent powder board, emits homogeneous gentle light, and can reach the functions of protecting eyesight and eliminating point light source.
Description
Technical field
The present invention relates to lighting and light source, refer in particular to a kind of LED area source.
Background technology
Existing LED light fixture and light source mostly are point light source light-emitting greatly on the market, are easy to generate dazzling dazzle, watch fatiguability even cause eyesight to descend for a long time;
Secondly, the fluorescent material of LED spot light directly contacts with led chip and substrate, is subjected to temperatures involved, easy weather stain of fluorescent material and volatilization, and influence luminous intensity and service life, and single luminous point, the fluorescent material consumption seldom is difficult to control well consumption, thereby strengthens colo(u)r bias easily.In addition, the point light source light-emitting effect is unfavorable for that product is attractive in appearance.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of LED area source, and it can avoid dazzle that existing spot light exists, easy to change, but and uniformly light-emitting.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of LED area source, comprise LED substrate and several LED that are installed on the LED substrate, the one phosphor plate support around described LED is set on the LED substrate, described phosphor plate support has an outwardly open interior tapered reflecting surface, has reflectorized material on the reflecting surface, install one on the described phosphor plate support and cover described LED and with described LED the phosphor plate of certain intervals is arranged, phosphor plate is towards the coating fluorescent powder of described LED.
Further improvement in the technical proposal is:
Described phosphor plate adopts light transmissive material to make.
Described LED substrate adopts Heat Conduction Material to make.
Described LED substrate is fixed on the housing by Heat Conduction Material.
Described phosphor plate support is made of plastics.
The invention has the beneficial effects as follows: because the light that LED sends is by behind the reflecting surface optically focused of phosphor plate support, shine the fluorescent powder on the phosphor plate uniformly, after female light that LED sends mixes with the sub-light of its excitated fluorescent powder generation is even, send the light of certain spectrum.By the outside transmission of phosphor plate, on phosphor plate, formed homogeneous light emitting area, send very evenly soft light, avoided the generation of dazzle, thoroughly eliminated dazzling phenomenon, reached vision protection and the thorough effect of eliminating spot light.
Description of drawings
Fig. 1 is a LED area source exploded view of the present invention;
Fig. 2 is the profile of LED substrate, phosphor plate support and phosphor plate part.
Below in conjunction with accompanying drawing the present invention is described further:
The specific embodiment
See also Fig. 1 and Fig. 2, LED area source of the present invention comprises housing 1, base 2, LED substrate 3 and is installed in several LED4 on the LED substrate, the one phosphor plate support 5 around several LED4 is set on LED substrate 3, phosphor plate support 5 has an outwardly open interior tapered reflecting surface 6, has reflectorized material on the reflecting surface 6, can make by the mode of electroplating or apply, install one on the phosphor plate support 5 and cover several LED4 and with several LED4 the phosphor plate 7 of certain intervals is arranged, phosphor plate 7 is towards the coating fluorescent powder 8 of several LED4.
Comprise lamp holder that general light fixture has, insulating barrier, radiator, power supply etc. in addition.
The light that LED4 sends shines the fluorescent powder 8 on the phosphor plate 7 uniformly by behind reflecting surface 6 optically focused of phosphor plate support 5, after female light that LED4 sends mixes with the sub-light of its excitated fluorescent powder generation is even, sends the light of certain spectrum.By phosphor plate 8 outside transmissions, on phosphor plate 8, formed homogeneous light emitting area, send very evenly soft light, avoided the generation of dazzle, thoroughly eliminated dazzling phenomenon, reached vision protection and the thorough purpose of eliminating spot light.
The appearance and modeling of product and illumination effect will both be had an aesthetic feeling fabulous luminous efficiency again, is the product of a light source and the ingenious perfect adaptation of aesthetic feeling.
