Abstract
The utility model LED spotlight (GU10), comprises metallic lamp body, lens, light source, aluminium base and plastic lamp base, and lens are arranged on metallic lamp body opening part, also comprises non-isolated power supply, adds insulating trip between metallic lamp body and non-isolated power supply.The utility model is by adopting non-isolated power drives, and drive efficiency reaches more than 85%, reduces the heat generation rate of whole lamp, improve the service life of shot-light, and cost is low.Light source is welded on after on aluminium base and is fixed on metallic lamp body again, ensure that whole lamp meets safety performance by the copper design of covering of aluminium base, adopt thermal conductivity to be more than or equal to the aluminium base of 2 watts/ meter Du simultaneously, both can meet insulating properties, and also reach good radiating effect.
Description
Technical field
The utility model relates to technical field of semiconductor illumination, particularly relates to LED spotlight (GU10).
Background technology
Shot-light, as accent light light fixture, is widely used in the places such as market, large supermarket, office space, museum, exhibition center, hotel, high-end residential, both can brightening environment, can beautify the environment again, for life is brought additional credit.LED spotlight still designs based on traditional halogen tungsten lamp in the market, adopts the supporting plurality of LEDs light source composition of optical lens, and shortcoming is that whole light electrical quantity is due to structure and driving power restriction, energy-saving effect is poor, radiating effect is poor, and service life is short, also cannot meet electric safety performance.
Summary of the invention
The LED spotlight that the technical problems to be solved in the utility model is to provide a kind of good energy-conserving effect, structural design meets electric safety performance.
The technical scheme realizing the utility model object is: LED spotlight (GU10), comprise metallic lamp body, lens, light source, aluminium base and plastic lamp base, lens are arranged on metallic lamp body opening part, also comprise non-isolated power supply, add insulating trip between metallic lamp body and non-isolated power supply, light source is fixedly connected with aluminium base, and aluminium base is arranged on metallic lamp body inside, plastic lamp base is arranged on the below of metallic lamp body, and non-isolated power supply is arranged on the inside of plastic lamp base.
As prioritization scheme of the present utility model, the thermal conductivity of aluminium base is more than or equal to 2 watts/ meter Du.
As prioritization scheme of the present utility model, aluminium base is for covering copper aluminium base.
The utility model has positive effect: adopt non-isolated power drives, drive efficiency reaches more than 85%, reduces the heat generation rate of whole lamp, improve the service life of shot-light, and cost is low.Light source is welded on after on aluminium base and is fixed on metallic lamp body again, cover copper design by the insulating properties of aluminium base and ensure that whole lamp meets safety performance, adopt thermal conductivity to be more than or equal to the aluminium base of 2 watts/ meter Du simultaneously, both can meet insulating properties, and also reach good radiating effect.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Fig. 1 is structure chart of the present utility model.
Wherein: 1, metallic lamp body, 2, lens, 3, light source, 4, aluminium base, 5, plastic lamp base, 6, non-isolated power supply, 7, insulating trip.
Detailed description of the invention
As shown in Figure 1, the utility model is LED spotlight (GU10), comprise metallic lamp body 1, lens 2, light source 3, aluminium base 4 and plastic lamp base 5, lens 2 are arranged on metallic lamp body 1 opening part, also comprise non-isolated power supply 6, insulating trip 7 is added between metallic lamp body 1 and light source 3, light source 3 is fixedly connected with aluminium base 4, it is inner that aluminium base 4 is arranged on metallic lamp body 1, plastic lamp base 5 is arranged on the below of metallic lamp body 1, non-isolated power supply 6 is arranged on the inside of plastic lamp base 5, and wherein the thermal conductivity of aluminium base 4 is more than or equal to 2 watts/ meter Du.Aluminium base 4 is for covering copper aluminium base.
Current existing product, uses the type of drive of pack alloy shell and insulating power supply, and withstand voltage being difficult to of whole lamp safety of metal is passed through, and needs higher insulation processing, and the insulating power supply of whole lamp drives and non-isolated side's power drives main distinction has two:
1, the efficiency of non-isolated power drives generally can reach about 85%, and the efficiency that insulating power supply drives is generally about 76%, and the efficiency height of driving not only can reduce the caloric value of whole lamp, improves overall service life simultaneously;
2, non-isolated power drives drives cost low than insulating power supply;
During use, in order to meet safety requirements needs, voltage-withstand test is carried out to whole lamp, insulating power supply self can pass through Hi-pot test due to architectural characteristic, but not insulating power supply cannot bear voltage-withstand test substantially, so need to have assisted by adding insulating part, namely between metallic lamp body 1 and non-isolated power supply 6, add insulating trip 7.
Light source 3 is COB light source, traditional COB light source is mainly divided into the aluminium base and ceramic base of two kinds of substrate material, and in order to ensure that light source fully contacts with lamp body, on substrate bottom surface gluing and light source, usually adding the installation fixed form of pressing plate, but be just applicable to isolation drive scheme.Non-isolated power drives COB light source cannot meet safety performance requirement according to this installation fixed form.Trendy high-power 5050 light sources of the CREE company that the design adopts, light source 3 is welded on after on aluminium base 4 and is fixed on metallic lamp body 1 inside again, the Safety Approval of whole lamp is ensured by the copper design of covering of aluminium base, adopt aluminium base also can not increase too much heat help and affect the heat radiation of light source simultaneously, adopt the aluminium base of thermal conductivity >=2 watt/ meter Du, both can meet insulating properties, also can reach the effect of heat conduction.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
