Description
Technical field
This utility model relates to a kind of light fixture, especially a kind of LED projector lamp.
Background technology
LED projector lamp is usually installed on the road surface being fixed on open air for illuminating, and its installation is fixing need to be convenient. Long-time powerful illumination, certainly will produce heat, it is necessary to good heat radiation. Being easily subject to External Force Acting out of doors, the structure in succession of Projecting Lamp need to be stablized firmly.
At present, LED projector lamp includes substrate, reflector, diffuser, LED light source, place the cavity of controller, support, described substrate caves in formation cavity backward, described LED light source and reflector are positioned at cavity, described LED light source is positioned at reflector, described diffuser is located on the front end face of substrate, and constitute the closing to described cavity opening, the rear end face of described substrate cavity is linearly evenly equipped with some radiating fins in left-right direction, the rear end face of described substrate cavity is additionally provided with the projection extended back, described projection length is more than radiating fin, the rear end face of described projection is connected with the cavity placing controller. this structure arranges more complicated, takes up room relatively big, and substrate front end is closed, and is unfavorable for heat radiation.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that a kind of simple in construction, the LED projector lamp of good heat dissipation.
To achieve these goals, the technical solution adopted in the utility model is: a kind of LED projector lamp, including substrate, reflector, diffuser, LED light source, place the cavity of controller, support, described substrate caves in formation cavity backward, described LED light source and reflector are positioned at cavity, described LED light source is positioned at reflector, one LED light source is provided with an independent diffuser, described diffuser is fixing with substrate to be connected, the cavity of described placement controller is arranged on the middle part of cavity rear end face, the upper and lower of described cavity rear end face is respectively equipped with transversely equally distributed heat sink, described heat sink length is along the two progressively longer settings in lateral middle part.
By such scheme it can be seen that there is an independent diffuser on a LED light source, the heat that LED light source distributes not easily is concentrated, substrate cavity rear end face is provided with heat sink, is conducive to heat radiation, and substrate cavity rear end face is provided with the cavity placing controller, saving space, structure is also simple.
Of the present utility model it is arranged so that described cavity rear end face is provided with the dividing plate being perpendicular to cavity rear end face further, one end of described dividing plate is provided with curved cover plate, the cavity placing controller is formed with described cavity rear end face, described heat sink and curved cover plate constitute arc and arrange, and described heat sink is fixing with cavity rear end face to be connected.
By such scheme it can be seen that cavity rear end face arranges cavity, place controller, reduce the space of LED projector lamp.Heat sink and curved cover plate constitute arc and arrange, and are conducive to cavity both sides to close, it is prevented that to leak.
Of the present utility model being arranged so that described substrate is provided with 4 and above equally distributed LED light source further, described diffuser can cover described LED light source, and is screwed connection.
By such scheme it can be seen that LED light source is uniformly distributed, diffuser independently covers each LED light source so that light projector is more uniform, and multiple LED light sources share light projector each other, and power can reduce, and a place is not concentrated in heat radiation, is also beneficial to heat radiation.
Of the present utility model it is arranged so that described cavity both sides are respectively provided with side plate further, the profile that described side plate is formed with heat sink, the placement cavity of controller, substrate is interlocked, described side plate is provided with the groove for connecting support, described groove is provided with the through hole of interspersed screw, is additionally provided with the fixing plate agreed with groove outside described side plate.
By such scheme it can be seen that the setting of side plate desirably prevents to leak, increase sealing property, side plate arranges groove and places support link, then pacify upper mounted plate, increase sealing property.
Of the present utility model being further arranged so that between described heat sink to be provided with screw mounting seat, described support is connected with screw mounting seat through the through hole on side plate by screw. .
By such scheme it can be seen that this setting makes support be more firmly mounted, increase service life.
Below in conjunction with accompanying drawing, this utility model is further described.
