Abstract

The utility model discloses a large-power LED floodlight which comprises a metal hanging ring 1, a lamp support 2, a switch power supply 3, a radiating aluminum piece 4, an aluminum substrate 5, a silica gel sealing pad 6, an acrylic lampshade 7 and a lampshade clamp 8. The metal hanging ring 1 is fixed on the lamp support 2 and used for hanging and installing of a lamp. The lamp support 2 serves as a radiator of the switch power supply 3, and the switch power supply 3 is tightly attached to and installed on the lamp support 2. The radiating aluminum piece 4 is connected to the aluminum substrate 5 in a riveted mode, and the aluminum substrate 5 is connected with the lamp support 2 through a screw. The edge of the aluminum substrate 5 is bent, and therefore the function of mechanical strengthening is achieved. The acrylic lampshade 7, the silica gel sealing pad 6 and the aluminum substrate 5 are tightly attached to one another through the lampshade clamp 8, and therefore the function of preventing dust and water is achieved.

Description

A kind of high-power LED floodlight
Technical field
The utility model relates to a kind of LED lamp for illumination on a large scale, is specifically related to a kind of high-power LED floodlight.
Background technology
LED floodlight is a kind of spot light of to all the winds uniform irradiation, and its range of exposures can be adjusted arbitrarily, shows as the diagram of a regular octahedron in scene.LED floodlight is mainly used to do the use of building decoration illumination, and commercial space illumination use, ornamental composition is heavier, and its external form has the round also side of having, because generally all must consider the reason of heat radiation, so its profile and traditional Projecting Lamp still have some differences.
Most LED floodlight adopts high-power integrated LED lamp pearl as light source, the heat that this great power LED integrated lamp bulb sends is very concentrated, to heat radiation, require very high, the LED lamp pearl of dispelling the heat if do not carry out can even damage because excess Temperature produces serious light decay, and old of heat abstractor is very high preferably.And most of LED floodlights adopt constant-current switch power source power supply, directly civil power being converted into the constant current direct current that voltage is higher exactly powers to LED lamp pearl, because aluminium base is directly fixed on lamp outer casing, lamp outer casing is generally aluminum alloy casing, between circuit above aluminium base and aluminium sheet matrix, insulating properties is poor, electric leakage easily occurs dangerous.
For addressing the above problem, the purpose of this utility model is to provide a kind of perfect heat-dissipating, fitting structure is compact, production cost is low a kind of high-power LED floodlight.First, the utility model adopts many less LED lamp of power pearls (as 1W lamp pearl) to be welded on aluminium base, and the spread heat that whole light fixture lamp pearl is produced comes.Owing to adopting special fin arrangement, make air flow through smoothly radiating aluminium sheet, reach good thermolysis.Again, the utility model not only as circuit carrier but also as the part of fitting structure part, kills two birds with one stone aluminium base, and reasonably space is arranged, makes light fixture size less.The 3rd, the utility model adopts square accessory, and stock utilization is high in process of production to make lamp fittings, reduces production costs; And light fixture size is less, required packaging material are few, saved resource.
Summary of the invention
The purpose of this utility model is to provide a kind of perfect heat-dissipating, fitting structure is compact, production cost is low novel large-power LED floodlight.
For achieving the above object, the technical solution of the utility model is: a kind of high-power LED floodlight of the utility model, comprises metal suspension ring 1, lamp bracket 2, Switching Power Supply 3, radiating aluminium sheet 4, aluminium base 5, silica gel sealing pad 6, acrylic lamp shade 7 and lampshade clamp 8.Described metal suspension ring 1 are fixed on lamp bracket 2, for suspension, mounted lamp; Described lamp bracket 2 is as the radiator of Switching Power Supply 3; Described Switching Power Supply 3 fits tightly and is installed on lamp bracket 2; Described radiating aluminium sheet 4 is riveted on aluminium base 5; Described aluminium base 5 adopts screw to be connected with lamp bracket 2, and the edge of aluminium base 5 adopts bending to process, and opens mechanical booster action; Described lampshade clamp 8 reaches dustproof and waterproof effect together with acrylic lamp shade 7, silica gel sealing pad 6 are fitted tightly with aluminium base 5.
A kind of high-power LED floodlight of the utility model, centered by aluminium base, welds LED lamp pearl and drive circuit on aluminium base, aluminium base edge takes bending to process, and strengthens aluminium base mechanical strength, overhangs height space for the element welding on aluminium base props up simultaneously; Multiple radiating aluminium sheets are riveted on aluminium base, and cuboid support is fixed Switching Power Supply and aluminium base position, form the lamp package of compact conformation.
Further, the utility model adopts rectangular shape, and cuboid upper surface is installed Switching Power Supply, and cuboid lower surface is installed LED aluminium base, and radiating aluminium sheet is installed in the middle of cuboid, and air can pass through fin smoothly, improves LED light fixture heat dispersion.
Further, the type of drive that the utility model adopts is: utilize Switching Power Supply that civil power is converted into low-voltage DC, then provide constant current by constant-current circuit, thereby on aluminium base, line voltage distribution is lower, light is controlled flexibly, reaches convenient and safe object.
Further, the utility model adopts square accessory, make lamp fittings in process of production material make full use of, loss is little, reduces production costs.
The utility model is compact conformation, safe and convenient to use not only, because square appearance makes material, more can make full use of, and reduces the wastage, thereby reduces cost, is applicable to producing in enormous quantities, promoting the use of.
