Description
Technical field
The present invention relates to a kind of is the bulb of light source with LED, belongs to the LED technical field of semiconductor illumination.
Background technology
Existing LED bulb mainly is made up of lamp holder, lamp socket, driver, radiator, led light source assembly, diffuser etc., 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 big, and overall system efficiency is low.Other has a kind of LED bulb is that led light source is integrated on the stem stem, places the cell-shell of sealing, and radiating efficiency is extremely low, and LED power can't be done greatly, and the whole light output of LED is low, is difficult to satisfy customer requirement.
Summary of the invention
Purpose of the present invention is exactly to improve at the deficiency of above-mentioned existing product, and a kind of high light efficiency, good heat dissipation effect are provided, the LED bulb of structure uniqueness.
The objective of the invention is to realize by existing LED bulb improved, a kind of high-efficiency LED bulb, comprise lamp holder, lamp socket, driver, radiator, led light source assembly, reflection shield, diffuser, it is characterized in that, be provided with fan, the first half of described radiator is provided with two or more two sides or multiaspect independence radiating block, the latter half is provided with the heat radiation cavity of hollow, fan is arranged between the independent radiating block and heat radiation cavity of radiator, and the led light source assembly is fixed on the independent radiating block of radiator; Reflection shield is fixed on the radiator, diffuser is fixed on the radiator and covers independent radiating block and go up the mounted LEDs light source assembly, lamp socket is installed with the latter half of radiator and is connected, and driver is installed on the lamp socket and places the heat radiation cavity of radiator the latter half hollow.
Described independent radiating block is the radiating block that is in the shape of the letter V, and V word mouth is towards bulb outer rim direction, and V word bottom is towards the bulb axis direction.
Described led light source assembly is a plurality of independently led light source assemblies, is separately fixed on a plurality of independent radiating block of radiator.
Be provided with air vent between described independent radiating block and the heat radiation cavity.
Described LED bulb profile is candle or circle or mushroom-shaped or olive shape.
Novel structure uniqueness of the present invention, scientific and reasonable, production and assembly are convenient, and cost is low, and whole artistry is good, good looking appearance, long service life.The first half of radiator is divided into the independent radiating block of a plurality of directions, outwards heat radiation on the outer surface of the latter half that the side and the heat of the heat that can be effectively led light source be produced by radiating block is transmitted to radiator, and area of dissipation is big.Simultaneously, inside at radiator has increased fan, can make full use of the incomplete connection between the independent radiating block of radiator the first half, form cross-ventilation, carry out forced heat radiation, improve radiating effect, be particularly conducive to the heat radiation of high-power LED bulb, and guarantee the service life of product.The latter half of lamp socket and radiator is fastened and connected by the mode of buckle, and driver is fixed in the cavity of lamp socket and radiator composition, forms the protection of circuit.Reflection shield adopts high reflecting material, and diffuser adopts the high transparent material of light transmittance, improves the luminous efficiency of LED bulb, realizes the high light efficiency purpose of light fixture.
