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 radiator, 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 LED bulb, comprise lamp holder, lamp socket, driver, radiator, the led light source assembly, reflection shield, diffuser, it is characterized in that, bulb is provided with the light-emitting zone of being made up of two or more independently little light-emitting zones, described little light-emitting zone is by the independent radiator on the radiator, the led light source assembly, reflection shield and diffuser constitute, described independent radiator is from radiator the first half extended one or two or a plurality of two sides or multiaspect radiators, the led light source assembly is fixed on the radiator, reflection shield is fixed on the radiator, diffuser is fixed on the radiator and covers the extended radiator of the first half and go up the mounted LEDs light source assembly, the latter half of radiator is the heat radiation chamber of hollow, and driver is installed on the lamp socket and places in the heat radiation chamber of radiator.
One or two or a plurality of lampshade (reflection shield and diffuser) are arranged on described each radiator.
On described each radiator the number of led light source assembly be one or two or a plurality of, the led light source assembly is fixed on one or two or a plurality of of radiator.
Described radiator is the radiator that is in the shape of the letter V, and the mouth of the V word of radiator is towards bulb outer rim direction, and V word bottom is towards the bulb axis direction.
Described LED bulb profile is candle or circle or mushroom-shaped or olive shape.
One or two or a plurality of lampshade (reflection shield and diffuser) are arranged on each radiator described in the present invention, on each radiator the number of led light source assembly be one or two or a plurality of, the led light source assembly can be fixed on one or two or a plurality of of radiator.Thus, can a little light-emitting zone on each radiator, a plurality of little light-emitting zones perhaps can be arranged.Like this, the LED bulb can utilize a plurality of independent radiators to come enhance heat on the one hand, on the other hand, utilizes a plurality of so little light-emitting zones, can satisfy the illumination in multiple different angles space.
The structure of more special a kind of radiator is the radiator that is in the shape of the letter V among the present invention, and the mouth of the V word of radiator is towards bulb outer rim direction, and V word bottom is towards the bulb axis direction.Wherein, the led light source assembly is installed in the bottom of V word mouth inboard, and like this, two sides of V word also can be used as reflective surface and use, and the light that LED is sent send through seeing through lampshade after reflecting.
The present invention is a kind of important breakthrough and the innovation to present LED bulb structure, seek heat-dissipating space by light source luminescent zone at bulb, bulb heat radiation and the luminous two-part structure of bulb are carried out organic combination, preferably resolve the problem that LED bulb volume is little, heat-dissipating space is not enough.Independent radiator structure of the present invention, novel unique, scientific and reasonable, production and assembly are convenient, and cost is low, and whole artistry is good, good looking appearance, 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 cavity of lamp socket and radiator composition, forms the protection of circuit.The first half of radiator is divided into the multiaspect radiator 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 radiator is transmitted to radiator, area of dissipation is big, good heat dissipation effect, be particularly conducive to the heat radiation of high-power LED bulb, and middle not exclusively connection can form cross-ventilation, guarantees the service life of product.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.
