Abstract
The utility model discloses a metal heat dissipation bowl LED ball bubble, including plastics lamp body, bottom trompil metal radiator and light -passing plastic cover, plastics lamp body and bottom trompil metal radiator fixed connection, the lower extreme of bottom trompil metal radiator has the aluminium base board of heat dissipation through the screw fixation, aluminium base board and drive power supply electric connection dispel the heat, the first -class angle of aluminium base board of dispelling the heat annular soldering tin has paster LED lamp pearl, bottom trompil metal radiator and light -passing plastic cover fixed connection. This bottom trompil metal heat dissipation bowl LED ball bubble, this principle mainly is through the aluminium base board and the bump contact of bottom trompil metal radiator that fits together with LED, the heat dissipation of bottom trompil metal radiator is given in the conduction that the heat of LED lamp pearl production can be quick, does benefit to quick heat dissipation, if the low lamp of metal radiator wattage may not also enough dispel the heat in the trompil.
Description
Technical field
This utility model belongs to technical field of lamps, is specifically related to a kind of heat dissipation metal bowl LED ball bubble.
Background technology
Light emitting diode (LightEmittingDiodeLED), is a kind of semiconductor subassembly.The appearance being used as the light LED such as display lamp, display light-emitting diode panel at the beginning, used also as illumination more.LED is referred to as forth generation lighting source or green light source, has the features such as energy-saving and environmental protection, life-span length, volume be little, is widely used in the fields such as various instruction, display, decoration, backlight, general lighting and urban landscape.
At present, the LED ball bubble of cabinet, the radiator included has two big classes；1, the radiator of aluminium alloy extrusions class, the shortcoming of this radiator is: the aluminium base contact area that radiator and LED fit together is little, and the heat on aluminium base can not quickly be transmitted on radiator；2, aluminium alloy aluminum bowl radiator, because shell is that plastics tightly encase aluminum bowl, it is impossible to make the air of heat sink part carry out convection current.
Utility model content
The purpose of this utility model is in that to provide a kind of heat dissipation metal bowl LED ball bubble, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: heat dissipation metal bowl LED ball is steeped, including plastic lamp housing, bottom opening metal heat sink and light-passing plastic cover, the upper end of described plastic lamp housing is fixed with lamp holder, and plastic lamp housing and bottom opening metal heat sink are fixing is connected, driving power supply it is provided with in cavity between described plastic lamp housing and bottom opening metal heat sink, the lower end of described bottom opening metal heat sink has been screwed radiator aluminium base plate, described radiator aluminium base plate is electrically connected with driving power supply, the first-class angle annular scolding tin of described radiator aluminium base plate has paster LED lamp bead, described bottom opening metal heat sink and the fixing connection of light-passing plastic cover.
Preferably, equidistant in the outer circumference of described plastic lamp housing it is provided with heat radiation glazing bar.
Preferably, described bottom opening metal heat sink is bowl-type structure.
Technique effect of the present utility model and advantage: this bottom opening heat dissipation metal bowl LED ball is steeped, compared with traditional bulb lamp, owing to this utility model is that LED ball steeps a kind of novel heat dissipation design principle, this principle mainly by with the LED aluminium base fitted together and bottom opening metal heat sink bump contact, the heat that LED lamp bead produces can quickly be conducted to the heat radiation of bottom opening metal heat sink；Bottom opening metal heat sink is monoblock molding, big with air contact area, is beneficial to quick heat radiating；Bottom opening metal heat sink bottom opening, in the shell of a plastics perforate, heat by the convection current of air, can quickly be taken away heat；This utility model is mainly used in having on the ball bubble of the cabinet of porous, if the lamp that metal heat sink wattage is low can not also enough dispel the heat in perforate, if perforate will be passed through when the high product heat radiation of wattage is fast not be reached the effect of rapidly heat radiation by air circulation.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model；
Fig. 2 is overall structure schematic diagram of the present utility model.
In figure: 1 lamp holder, 2 plastic lamp housings, 3 driving power supply, 4 bottom opening metal heat sinks, 5 radiator aluminium base plates, 6 paster LED lamp bead, 7 screws, 8 light-passing plastic covers.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
nullThis utility model provides heat dissipation metal bowl LED ball bubble as shown in Figure 1-2，Including plastic lamp housing 2、Bottom opening metal heat sink 4 and light-passing plastic cover 8，Equidistant in the outer circumference of described plastic lamp housing 2 it is provided with heat radiation glazing bar，The upper end of described plastic lamp housing 2 is fixed with lamp holder 1，And plastic lamp housing 2 and bottom opening metal heat sink 4 is fixing is connected，Described bottom opening metal heat sink 4 is bowl-type structure，Driving power supply 3 it is provided with in cavity between described plastic lamp housing 2 and bottom opening metal heat sink 4，The lower end of described bottom opening metal heat sink 4 is fixed with radiator aluminium base plate 5 by screw 7，Described radiator aluminium base plate 5 is electrically connected with driving power supply 3，The first-class angle annular scolding tin of described radiator aluminium base plate 5 has paster LED lamp bead 6，Described bottom opening metal heat sink 4 and the fixing connection of light-passing plastic cover 8.
Structural principle: ball of the present utility model bubble shell adopts plastic material, built-in many paster LED lamp bead 6, the bulb lamp that paster LED lamp bead 6, driving power supply 3, bottom opening metal heat sink 4 and light-passing plastic cover 8 etc. form；Dispelling the heat with metal bowl, material purity is high, rapid heat dissipation, and convenient processing and manufacture is quick, and ratio is with the radiator low price of aluminium alloy extrusions, and ratio is with cabinet with mould alclad shell good heat dissipation effect but also cost performance is high；Radiator aluminium base plate 5 bump contact that bottom opening metal heat sink 4 and paster LED lamp bead 6 assemble, the heat that paster LED lamp bead 6 produces quickly can be conducted to bottom opening metal heat sink 4 by radiator aluminium base plate 5 and dispel the heat；Bottom opening metal heat sink 4 is monoblock molding, big with air contact area, is beneficial to quick heat radiating；Bottom opening metal heat sink 4 bottom opening, plastic lamp housing 2 top drilling, product is after assembling, and when product is lighted, air carries out convection current at heat sink part, effectively reduces the product temperature impact on lamp bead, extends the service life of product.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent replacement; all within spirit of the present utility model and principle; any amendment of being made, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
