Further, the Projecting Lamp also includes a lamp bracket, and the lamp bracket two ends are fixedly connected power shelf.

Further, the PC lens jackets, silica gel waterproof layer are square or rectangle.The power shelf and lamp bracket are It is U-shaped.

Further, the through hole of multiple radiatings is offered on the heat-dissipating aluminium plate.

Further, the lampshade and power shelf are made of aluminium.

Compared with prior art, using LED projector lamp described in the utility model, light goes out by PC lens direct irradiations Come, improve the utilization rate of light, because the volume and weight for not using reflection shield, light fixture is substantially reduced, the reduction of light fixture cost While also reduce cost of transportation；Power supply is fixed on the power shelf of aluminum simultaneously, away from heat-dissipating aluminium plate, so that effectively The environment temperature of power supply is reduced, the service life of power supply is improve；In addition, the utility model, manufactures simpler, efficiency more Height, beneficial to being widely popularized and apply.There is light efficiency high, low cost, lightweight, convenient transportation.

Brief description of the drawings

Fig. 1 is the sectional structure chart of the LED projector lamp described in the utility model embodiment.

Specific embodiment

Come to be described further the utility model below in conjunction with the accompanying drawings, but not as to restriction of the present utility model.

As shown in figure 1, a kind of LED projector lamp, including lampshade 5, power supply lead wire 3, supply convertor 2, power shelf 4, its In, the cover bottom of the lampshade 5 be heat-dissipating aluminium plate, be installed with the heat-dissipating aluminium plate PC lens jackets 6, silica gel waterproof layer 8, Aluminium base flaggy 7 and power shelf 4, wherein, the power shelf 4 is located at heat-dissipating aluminium plate top, the PC lens jackets 6, silica gel , located at heat-dissipating aluminium plate lower section, located at the top of PC lens jackets 6, PC lens jackets are as lid one for aluminium base flaggy 7 for waterproof layer 8, aluminium base flaggy 7 Sample covers on aluminium base flaggy 7 on heat-dissipating aluminium plate, in order to prevent water from being penetrated between PC lens jackets 6 and heat-dissipating aluminium plate, in radiation aluminium Silica gel waterproof layer 8, the silica gel waterproof layer 8 has been added to be embedded in PC lens jackets 6 between plate and PC lens jackets 6, supply convertor 2 Be fixed on the top of power shelf 4, the power supply lead wire 3 from supply convertor 2 pick out and with aluminium base flaggy 7 on LED between It is connected, LED is evenly distributed on the outer surface at the place of aluminium base flaggy 7.The Projecting Lamp also includes a lamp bracket 1, the light fixture The two ends of support 1 are fixedly connected the power shelf 4 by screw.

Wherein, the PC lens jackets 6, silica gel waterproof layer 8 are square or rectangle.The power shelf 4 and lamp bracket 1 are It is U-shaped.The through hole of multiple radiatings is offered on the heat-dissipating aluminium plate.The lampshade 5 and power shelf 4 are made of aluminium.Adopt With the lampshade shell of aluminum also good heat conduction effect, and the light transmittance of PC lens jackets 6 is up to more than 90%.Power supply is isolated with heat-dissipating aluminium plate Separate, protect light source prolonging service lives of lamps.
