Abstract

The utility model discloses an LED streetlamp bulb. A plurality of LED lamps are assembled on a rectangular lamp panel which is arranged on the plane of a semi-cylindrical lower lamp body; the upper surface of the lower lamp body and the back surface of the lamp panel are provided with an upper lamp body which is also semi-cylindrical but shorter; the front surface of the lower lamp body is provided with a round front cover, and the rear surface thereof is provided with a round rear cover; a semi-cylindrical hollow transparent cover is arranged between the upper lamp body and the front cover, thus forming an integrated cylinder; the tail end of the rear cover is provided with a screwed lamp cap; the lower lamp body and the upper lamp body are made of aluminium alloy and provided with radiating fins at the outside surfaces; and the front cover and the rear cover are respectively provided with a circle of radiating holes. The LED streetlamp bulb has pure color temperature and is very energy-saving by adopting an LED lamp as a light source, is extremely good in radiating effect and greatly prolongs the service life by adopting the aluminium alloy lamp bodies with radiating fins, and is convenient for replacement without transformation on a lamp holder and a power supply system as the shape of the lamp body is similar to that of a common bulb.

Description

The LED street lamp bulb

Technical field

The utility model relates to the public lighting light fixture, particularly a kind of energy-conservation LED street lamp bulb.

Background technology

Public lighting is a link important in urban construction and the rural construction, and a great contradiction is arranged here, is exactly brightness of illumination and energy-conservation contradiction.Usually wish that public lighting brightness is higher, better lighting environment can be provided at night.High brightness will high energy consumption, will cause electric energy consumption, electric power system high load capacity and need big load system, this is again undesirable.

Energy-saving lamp is a lot of now, but mostly different with original road lamp system, needs special-purpose electric power system, can cause the increase of investment again, and this is again a contradiction.

The utility model content

For solving above-mentioned contradiction, the utility model provides a kind of energy-conservation, simple and easy LED street lamp bulb that easily changes.

The utility model LED street lamp bulb, comprise several LED lamps, wherein: described several LED lamps are assemblied on the rectangle lamp plate, lamp plate is installed on the plane of a semi-cylindrical down lamp body, and back following above the lamp body, lamp plate is provided with and is similarly semicolumn but shorter last lamp body, and a circular protecgulum is established in the front of following lamp body, a circular bonnet is established in the back, be provided with semi-cylindrical hollow translucent cover between last lamp body and the protecgulum, form complete cylindrically, the bonnet end is provided with screw holder.

The utility model LED street lamp bulb, wherein: described lamp body down and last lamp body are made of aluminium alloy, and there is the heat radiation wing outside.

The utility model LED street lamp bulb, wherein: a circle louvre is respectively arranged on described protecgulum and the bonnet.

The utility model LED street lamp bulb, wherein: described going up has two installation screws on the lamp body, be screwed on following lamp body, and synthetic one is cylindrical.

The utility model LED street lamp bulb, wherein: cover installing hole on described protecgulum and the bonnet, have three on the protecgulum, be screwed on following lamp body, have six on the bonnet, be fixed on simultaneously on lamp body and the last lamp body with screw.

The utility model LED street lamp bulb, wherein:: described lamp plate edge is provided with six Long Circle plate installing holes, is fixed on down on the lamp body with six screws, is covered with above it and the corresponding half-cylindrical translucent cover of last lamp body.

The utility model LED street lamp bulb, wherein: draw two lines central point and the screw ring of connecting screw lamp holder respectively after the LED lamp connection in series-parallel on the described lamp plate.

The utility model LED street lamp bulb adopts the LED lamp as light source, and colour temperature is pure, and is very energy-conservation; Adopt the aluminium alloy lamp body of band heat radiation wing, radiating effect is fabulous, increases the service life significantly; The similar common bulb of lamp body shape is convenient to change and is need not lamp socket and electric power system transformation.
