Description
Technical field
The utility model relates to a kind of bulb take LED as light source, belongs to the LED technical field of semiconductor illumination.
Background technology
Existing LED bulb mainly is comprised of lamp holder, lamp socket, driver, radiator, led light source assembly, diffuser etc., a kind of is the diffuser of bulb is divided into several parts gathers with radiating block in order to solve heat dissipation problem, has destroyed the aesthetic habit of conventional bulb.A kind of is to adopt reflective device to carry out luminous intensity distribution, all heats only dispel the heat by single-ended radiating block, its shortcoming is that area of dissipation is little, power can't be done greatly, total output light flux of LED bulb is low, and the reflecting and light distributing light loss is large, and overall system efficiency LED power can't be done greatly, the whole light output of LED is low, is difficult to satisfy customer requirement.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of LED bulb of efficient, good heat dissipation effect is provided.
The purpose of this utility model is achieved in that a kind of LED bulb, comprise lamp holder, lamp socket, driver, radiator, led light source assembly, diffuser, described lamp socket is connected with radiator, the integral part of radiator is hollow structure, described driver is arranged on the bottom in the radiator, top in the radiator arranges some radiating fins, and some radiating fins form the first gas channel, and the second gas channel that is connected with the first gas channel is set on the radiator; Described led light source assembly is connected on the radiator, and radiator and led light source assembly are arranged in the diffuser.
The up and down two ends of diffuser of the present utility model arrange respectively through hole.
The utility model novel structure is unique, and scientific and reasonable, production and assembly are convenient, and cost is low, radiating effect, long service life.The latter half of lamp socket and radiator is fastened and connected by the mode of buckle, and driver is fixed in the independent cavity of lamp socket and radiator composition, forms the protection of circuit.The first half of radiator is the shape of hollow, extend to cavity top and bottom surface in the cavity of radiating fin by hollow, up and down to logical and form cross-ventilated passage, on the outer surface of the top and the bottom that side and the fin face of the heat that can be effectively led light source be produced by radiator is transmitted to radiator, conduct by the heat with air again, heat is delivered in the air the most at last, realizes the dissipation of heat of light fixture.The area of dissipation of radiator is large, and good heat dissipation effect is particularly conducive to the heat radiation of high-power LED bulb, and adopts hollow structure to make the middle fully perforation of radiator, can form cross-ventilation, guarantees the service life of product.The integral light-transmitting cover adopts the high transparent material of integral light-transmitting rate, when keeping conventional bulb integral light-transmitting outer cover outward appearance, improves the luminous efficiency of LED bulb, realizes the high light efficiency purpose of light fixture.
