The specific embodiment
The present invention relates to the LED lamp plate radiator structure used on a kind of LED stage lamp.LED light fixture as shown in Figure 7, comprise heat radiation protecgulum (1), radiating seat (2), be arranged on the waterproof apron (16) between heat radiation protecgulum (1) and radiating seat (2), safety glass (17), lens assembly (18) and lamp plate (19); Back casing (20) and be arranged on the support (21) on back casing (20).
As shown in Figure 1 LED lamp plate radiator structure comprise heat radiation protecgulum (1) and radiating seat (2).
As shown in Figures 2 to 6, heat radiation protecgulum (1) is divided into interior ring (3), radiating ribs a (5), outer shroud (4); Ring (3) and outer shroud (4) in radiating ribs a (5) is connecting, play a part to connect, strengthen and heat radiation.Radiator window B (10) is arranged between two radiating ribs a (5).Radiating seat (2) front is divided into inner ring (7), radiating ribs b (9), outer ring (8); Radiating ribs b (9) is connecting inner ring (7) and outer ring (8), plays a part to connect, strengthens and be heat radiation.Radiator window B (10) is arranged between two radiating ribs b (9).Radiator window A (6) and radiator window B (10) are for one to one, and both run through before and after lamp body, can allow convective air flow logical, play a part wind guide tank.
Heat radiation is with a plurality of screw holes outside protecgulum (1) back side, and the positive outermost of radiating seat (2) also has a plurality of screw holes, and heat radiation protecgulum (1) is connected by these several screw holes with radiating seat (2).
Radiating seat (2) back side is divided into inside and outside two-layer, and inside and outside have a heat dissipating ring (12) between two-layer, can, so that air forms convection current, strengthen radiating effect.The inside and outside two-layer a plurality of fin (11) that have respectively, fin (11) is arranged and is fan-shaped, has greatly increased the fan hot side long-pending, between fin (11), wind guide tank is arranged simultaneously, can be so that convection current wind connect, thus further raising radiating effect.
Be with a plurality of screw holes outside the radiating seat front is inferior, this screw hole is used for fixing the LED lamp plate; There is a connecting axle (14) in radiating seat central authorities, and connecting axle has several screw holes above (14), by these several screw holes, radiating seat are connected with back casing.
When LED works, LED chip can produce a large amount of heats, and the heat that LED produces is transmitted on radiating seat and heat radiation protecgulum; Part heat on radiating seat is lost in air by fin, simultaneously, because the radiator window B of the heat radiation radiator window A of protecgulum and radiating seat is corresponding one by one, mutually connect, therefore can form convection current wind in 2 radiator windows, thereby take away the part heat, and, 2 radiator windows have reduced the windage of radiating seat and heat radiation protecgulum convection current wind greatly, have therefore greatly improved radiating effect; In addition, the fan-shaped two-layer fin of arranging in the radiating seat back side, increased area of dissipation, heat dissipating ring between two-layer fin has effectively strengthened convection current wind, reduced windage, and the wind guide tank between fin and fin is also mutual perforation, effectively strengthened convection current wind, like this, radiating effect has also been strengthened greatly.
