Abstract
The utility model discloses a large-power LED (light-emitting diode) projection lamp, which is composed of a lamp stand and a lamp body arranged in the lamp stand, wherein the lamp body comprises a lampshade, an LED integrated light source and a heat dissipater; the LED integrated light source consists of more than two groups of LED module light sources which are arranged symmetrically in a wing shape; a conducting tube penetrates the LED module light sources; the other end of the conducting tube penetrates in a heat conducting hole of the heat dissipater; the heat dissipater consists of a plurality of heat dissipating modules which are overlapped horizontally; light source mounting holes are formed symmetrically in the lampshade; and the LED integrated light source is arranged in the light source mounting holes in a matching way. As the two wings give out light, the lighting effect and the projection range are ensured. Due to the design of the heat dissipater, the large-power LED projection lamp can ensure that air flows in gaps between heat dissipating fins, thereby increasing air convection and improving heat dissipation effect. In addition, the user can add or reduce the number of light source modules and heat dissipating modules according to the use requirements, so as to meet different application requirements.
Description
Technical field
The utility model relates to the LED lighting technical field, relates in particular to a kind of high power LED projector.
Background technology
Tunnel Lamp uses in railway, highway and pedestrian tunnel usually.Because tunnel space is comparatively narrow and small, in order to guarantee driving or pedestrains safety, so require road surface brightness big, the light uniformity is high, and long service life is so the requirement of contrast bright lamp is higher.The problem that traditional LED Tunnel Lamp exists has: 1. all have only a light source, average illuminance does not reach instructions for use.2. some LED are installed on the radiator, and not only assembling is inconvenient, processing cost is high but also radiating effect does not reach assurance, causes its service life shorter.
The utility model content
The utility model provides a kind of illuminance high in order to solve the problems of the technologies described above, the high power LED projector of good heat dissipation effect.
A kind of high power LED projector is made up of lamp bracket and the lamp body that is arranged in the lamp bracket; Said lamp body comprises lampshade, LED integrated optical source and heat abstractor; Said LED integrated optical source is formed by being the symmetrically arranged LED die set light source of aerofoil profile more than two groups; The interspersed conduit that is provided with in the LED die set light source, the other end of said conduit is interspersed to be arranged in the thermal hole of heat abstractor; Said heat abstractor is made up of the heat radiation module of the overlapping setting of several levels; Symmetry offers the light source installing port in the said lampshade, and the cooperation of LED integrated optical source is installed in the light source installing port.
Said lamp bracket comprises main frame and back shroud, and main frame is provided with light source shelf and heat radiation rack, and lampshade and cloche are installed in the light source shelf through preceding buckle, and heat abstractor is fixed in the heat radiation rack through cover sheet.
Also be provided with installing rack on the said main frame.
Said back shroud is provided with the lateral projection cylindrical void.
The utility model adopts double-vane luminous, has guaranteed light efficiency and light projector scope.The design of heat abstractor can guarantee that air circulates between the gap of radiating fin, increased the convection current of air, has improved radiating effect.Simultaneously can be according to the use needs, the quantity of increase and decrease light source module and heat radiation module has satisfied different ranges of application.
