Technical field
The invention belongs to the technical field of LED electricity-saving lamp, special luminous with omnidirectional LED modulated structure is relevant.
Technical background
As everyone knows, LED illuminating product is more and more favored by people as novel Green Product, market is just increasing with exponential form, relevant technical standard is also gradually improved, the standard that the star of american energy of wherein take is representative to the technical indicator of this product made very comprehensively, the unusual standard of science, especially product luminous intensity distribution has been proposed to very strict requirement, but be the birth defect of this product for the very little lighting angle of LED product.How allowing the lighting angle of LED lamp meet the requirement of the star of american energy, is the technical essential of this case.
Summary of the invention
The object of the present invention is to provide a kind of omnidirectional light emitting LED lamp, to expand lighting angle, improve light emission rate.
In order to reach above-mentioned purpose, technical scheme of the present invention is:
Omnidirectional's light emitting LED lamp, is comprised of lampshade, lamp body, drive circuit and LED light source plate, and drive circuit is arranged in lamp body, and LED light source plate is arranged on lamp body and with drive circuit and is connected, and lampshade is located on lamp body; Notch cuttype catoptric arrangement is also installed on LED light source plate, so-called notch cuttype catoptric arrangement is at least comprised of two-layer stacked reflecting plate, the top surface of every one deck reflecting plate and basal surface are all reflectings surface, the center of every one deck reflecting plate all forms transparent area, the area of lower one deck reflecting plate is greater than the area of last layer reflecting plate, and the transparent area of lower one deck reflecting plate is over against last layer reflecting plate.
On described LED light source plate, form reflecting surface.
The periphery of described every one deck reflecting plate all upwards arches upward, and makes top surface and basal surface all form cambered surface, and every one deck reflecting plate is horn-like.
Described notch cuttype catoptric arrangement is comprised of two-layer reflecting plate, the top surface of lower floor's reflecting plate and basal surface upwards arch upward with different amplitudes, the top surface amplitude of arching upward of setting layer reflecting plate is L11, the basal surface amplitude of arching upward of lower floor's reflecting plate is L12, top surface and the basal surface of upper strata reflecting plate upwards arch upward with same magnitude, if the amplitude of arching upward of upper strata reflecting plate is L2, L12 ﹤ L2 ﹤ L11.
The sizableness of the size of described last layer reflecting plate and lower one deck reflecting plate transparent area.
Described transparent area is through hole, or transparent area is transparent panel.
On described LED light source plate, transparent rack is installed, support has leg and transparent ladder, and the lower end of leg is fixed on LED light source plate, and reflecting plate is fixed on transparent ladder successively.
Adopt after such scheme, the present invention is simple in structure, low cost of manufacture, because notch cuttype catoptric arrangement has been installed on LED light source plate, light Hui Fen tri-tunnels that LED light source plate produces are penetrated: a road is avoided notch cuttype catoptric arrangement (orlop reflecting plate) and directly upwards from surrounding, penetrated, another road is irradiated to the basal surface of orlop reflecting plate, through reflection, penetrates or upwards reflects from surrounding and penetrate again through reflexing to LED light source plate downwards again from surrounding, and Third Road sees through transparent area and upwards penetrates, Third Road Zai Fen tri-tunnels that this penetrates from transparent area a: road is avoided notch cuttype catoptric arrangement (inferior lower floor reflecting plate) and directly upwards penetrated from surrounding, another road is irradiated to time basal surface of lower floor's reflecting plate, through reflection, from surrounding, penetrate or upwards reflect and penetrate from surrounding again through reflexing to orlop reflecting plate downwards again, Third Road sees through transparent area and upwards penetrates ... so repeatedly, light is constantly reflected, be fully used, light emission rate is greater than 90%, lighting angle is greater than 300o, light distribution meets the star newest standards requirement of american energy, and transparent area can be eliminated top hot spot, better effects if.
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Accompanying drawing explanation

Label declaration
The specific embodiment
As shown in Figure 1 to Figure 3, the present invention has disclosed a kind of omnidirectional light emitting LED lamp, lampshade 1, lamp body 2, drive circuit 3 and LED light source plate 4, consists of.Drive circuit 3 is arranged in lamp body 2, and LED light source plate 4 is arranged on lamp body 2 and with drive circuit 3 and is connected, and lampshade 1 is located on lamp body 2.
The improvement of this case is: notch cuttype catoptric arrangement is also installed on LED light source plate 4, so-called notch cuttype catoptric arrangement at least by two-layer stacked reflecting plate 5 and 6 form (number of reflecting plate is not limit, this embodiment take two describe as example).Reflecting plate 5 and 6 top surface and basal surface are all reflectings surface, and reflecting plate 5 and 6 center all form transparent area 51 and 61, and the area of lower one deck reflecting plate 5 is greater than the area of last layer reflecting plate 6, and the transparent area 51 of lower one deck reflecting plate 5 is over against last layer reflecting plate 6.In order to improve reflection efficiency, on LED light source plate 4, also can form reflecting surface.
When the present invention uses, coordinate shown in Fig. 4 (arrow represents light), light Hui Fen tri-tunnels that LED light source plate 4 produces are penetrated: a road A1 avoids reflecting plate 5 and directly upwards from surrounding, penetrates, another road A2 is irradiated to the basal surface of reflecting plate 5, through reflection, penetrate or upwards reflect from surrounding and penetrate again through reflexing to LED light source plate 4 downwards again from surrounding, Third Road A3 sees through transparent area 51 and upwards penetrates.Third Road A3 is Zai Fen tri-tunnels from transparent area 51 penetrates: a road B1 avoids reflecting plate 6 and directly upwards from surrounding, penetrates, another road B2 is irradiated to the basal surface of reflecting plate 6, through reflection, penetrate or upwards reflect from surrounding and penetrate again through reflexing to reflecting plate 5 downwards again from surrounding, Third Road B3 sees through transparent area 61 and upwards penetrates.So repeatedly, light is constantly reflected, be fully used, light emission rate is greater than 90%, and lighting angle is greater than 300o, and light distribution meets the star newest standards requirement of american energy, and transparent area 51 and 61 can be eliminated top hot spot.
In order to reach better reflecting effect, this embodiment upwards arches upward the periphery of reflecting plate 5 and 6, makes top surface and basal surface all form cambered surface, and it is horn-like that reflecting plate 5 and 6 is all.And, the sizableness of the size of reflecting plate 6 and reflecting plate 5 transparent areas 51 in this embodiment.In addition, the top surface of reflecting plate 5 and basal surface upwards arch upward with different amplitudes, if the top surface amplitude of arching upward of reflecting plate 5 is L11, the basal surface amplitude of arching upward of reflecting plate 5 is L12, top surface and the basal surface of 6 reflecting plates upwards arch upward with same magnitude, if the amplitude of arching upward of reflecting plate 6 is L2, this embodiment special design L12 ﹤ L2 ﹤ L11, makes light multipath reflection more abundant.
Above-described embodiment and graphic and non-limiting product form of the present invention and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present invention.
