A kind of LED lamp

Technical field

The utility model relates to a kind of with cover with the LED lamp of LED as the PAR lamp series of light source.

Background technology

Along with the continuous development of LED technology, LED not only is applied in special lighting fields such as indicator lamp, backlight, and begins to apply to widely various general lightings field as the substitute products of incandescent lamp, electricity-saving lamp.The early stage product that occurs is that the LED lamp is installed in the plastics Lamp cup, this product is poor owing to radiating effect, the brightness of LED lamp is little and the low inferior reason of light efficiency have the physical life of LED lamp short, be difficult to satisfy significant deficiency such as normal illumination needs.In order to solve brightness problem, afterwards the product of Chu Xianing mostly in a Lamp cup a plurality of LED lamps of serial or parallel connection increase brightness, though this technology has solved the problem of illuminance deficiency, must bring bigger caloric value owing to increase light source, dispelled the heat into a great problem of this technical field.In recent years, because the light efficiency of LED lamp is constantly improved the luminance shortage problem of a LED lamp.Be eased to a certain extent, because the LED lamp is subjected to the restriction of conventional lights moulding and volume, that can not volume does is too big, and heat dissipation problem is still the subject matter that restricts the LED lamp.

At present, the LED lamp adopts lens to assemble the light that LED sends basically on the market, but this method is because the light-receiving area of lens is limited, and some light does not make full use of, and causes certain light loss.

Summary of the invention

The technical problem that the utility model solves is: a kind of LED lamp is provided, has good circulation of air radiator structure.Because the light that LED sent uses lens to assemble usually greater than 140 degree, is difficult to assemble all light, surpasses the above light of 180 degree and use reflection shield to assemble, to obtain luminous flux to greatest extent.

Because LED uses normally steady operation of constant-current source usually, will use big more electronic component and design satisfactory constant-current source, also will consider effective isolation of strong and weak electricity, so general constant-current source can be bigger.And standard lamp metal cup volume is less, the constant-current source of the larger volume of can't packing into.The utility model has designed embedded, and the strong and weak electricity separated structures has made full use of limited space.Built-in part increases an insulating lid, and power supply (strong power part) is in the space of a reinforced insulation of being made up of lamp socket and insulating lid (CLASS 2).

Specifically, the technical solution of the utility model is: a kind of LED lamp is provided, comprise metal cup and the lamp socket that is connected this metal cup lower end, in described metal cup, be provided with the LED assembly, on the rim of a cup of described metal cup, be provided with cover, described LED assembly comprises LED and power rectifier and filter circuit, on described lamp socket, be provided with insulating lid, described lamp socket and insulating lid constitute an obturator, be provided with power supply circuits (strong power part) in described obturator, described power supply circuits (strong power part) are connected with the LED assembly by lead.

Be provided with radiating fin on described metal cup, described radiating fin and described metal cup are structure as a whole.

Described radiating fin upper end is discrete separation shape.

Be provided with louvre around described cover, described louvre is corresponding at interval with the radiating fin of described metal cup, and air-flow is circulated up and down.

Bottom at described metal cup is provided with groove, and the top of described lamp socket is embedded in the described groove.

On described LED, be provided with reflection shield.

Described cover is located at the reflection shield top, and compresses reflection shield.

The utility model is provided with the structure of power supply circuits (strong power part), like this owing to adopted lamp socket and obturator of insulating lid formation in described obturator, make the intact portion of strong power part be enclosed in this space, really realized the strong, weak electricity separation, therefore, it has very high security; In addition, the utility model has adopted in the bottom of described metal cup and has been provided with groove, and the top of described lamp socket is embedded in the structure in the described groove, has so just made full use of limited space, can make the utility model and the supporting use of existing lamp holder.
