The specific embodiment

Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated.

Fig. 1 shows the structural representation of the LED lighting device in the utility model.As shown in Figure 1, described LED lighting device comprises: shell 13, support 1, LED wafer 2, handware 14 and lamp holder 15.Described LED wafer 2 is arranged on the described support 1.Preferably, described support 1 adopts aluminium or copper material to make, and it described LED wafer 2 as the pin stent support, and plays the effect of conduction and heat radiation.Preferably, described shell 13 is glass shells, and preferably, described glass shell is transparent, frosted or whitewashes.Preferably, also be provided with opening 3 on the described support 1, to strengthen the light transmittance of described LED lighting device.Preferably, described handware 14 is copper spare or fine aluminium spare.

Fig. 2 shows the LED wafer and is closed the back as the core luminous component.As shown in Figure 2, described LED wafer is closed the back as the core luminous component, and preferably, described LED wafer 2 is fixed on the described support 1 by elargol 9, described elargol 9 is as Heat Conduction Material, thereby the heat that described LED wafer 2 sends is transmitted on the described support 1 faster and better; The both positive and negative polarity of described LED wafer 2 is electrically connected with the both positive and negative polarity of described support 1 respectively by gold thread 12.Scribble fluorescent material 10 on the described LED wafer 2, preferably, described LED wafer 2 is blue light-emittings, and described fluorescent material is yellow.By the debugging of processing compound, can make described LED wafer 2 send the light of different-colour.Outer setting at described fluorescent material 10 has layer of silica gel 11, thereby makes the light-emitting area journey of described LED wafer more strengthen and protect the extruding that gold thread is subjected to the external world.Preferably, described layer of silica gel 11 ovalizes, thus can make light-emitting area increase 1.5 times.
