The specific embodiment
A following embodiment who describes the LED illumination lamp housing of the utility model with reference to figure 1-Fig. 5 in detail:
Like Fig. 1-shown in Figure 5; The utility model mainly includes the cylindrical body 1 of a hollow-core construction; This cylindrical body 1 upper end is provided with first connecting portion 2 that is used for being connected with the external stability seat; The lower end then is provided with second connecting portion 3 that is used to connect light shield 4, is distributed with the radiating fin 11 of some vertical settings at this outer surface of 1 of said cylindricality.The width of said cylindrical body 1 greater than the width of first connecting portion 2, between the said cylindrical body 1 and first connecting portion 2, form first step face 5; The width of said second connecting portion 2 is greater than the width of said cylindrical body 1; Between the said cylindrical body 1 and second connecting portion 3, form second step face 6; And the thickness of said radiating fin 11 increases from top to bottom gradually, with said second step face 6 butts and terminate in its outer.Said first connecting portion 2 and/or first step face 5 are provided with some first steam vents 51, on said cylindrical body 1 lower end or said second step face 6, also are provided with some second steam vents 61.As an implementation of present embodiment, said first steam vent, 51 quantity can be 2, L-shaped said first connecting portion 2 and said first step face 5 intersections of being arranged on; The quantity of said second steam vent 61 can be four, is evenly distributed on the said second step face 6 near the outer rim of said cylindrical body 1, perhaps is evenly distributed on the lower end of said cylindrical body 1 near said second step face 6.Through said first steam vent 51 and second steam vent 61 are set, the inner air of LED lamp is heated afterwards produces convection current, take away the heat energy on LED lamp power supply and the chip, reduced junction temperature.
In addition, said cylindrical body 1 is provided with the chip (not shown) in also, and said chip (not shown) is fixed in the said cylindrical body 1 through the screw suspension, and with the said cylindrical body 1 preset spacing of being separated by.Adopting heat-conducting glue that chip is bonded on the lamp housing with prior art compares; Present embodiment is fixed on the chip suspension on the lamp housing through adopting screw; Making it has certain spacing with cylindrical body 1; Dispel the heat through cross-ventilation, through experiment, its cross-ventilation radiating effect obviously is better than the thermal conduction effect of prior art.
During concrete the realization, said first connecting portion 2 can be and is provided with externally threaded screw socket.Said second connecting portion 3 is provided with the loop configuration of lamp housing draw-in groove 31 for inner surface.
In addition, because mostly the LED illuminating lamp shade sheathing material of prior art is that engineering plastics or aluminium alloy combine with engineering plastics, the engineering plastics that one deck is used to insulate are all wrapped up in its inside; The engineering plastics thermal conductivity is very low; Its thermal conductivity is merely 0.03～0.17W/ (m.K), therefore, and for the thermal conductivity that improves lampshade is considered; The LED illuminating lamp shade of present embodiment can adopt ceramic material to process; The thermal conductivity of ceramic material is that 2.9～21W/ (m.K) has strengthened heat-conducting effect greatly, really reaches insulation, anti-creeping effect.
