Description

A kind of LED bulb
Technical field
The utility model relates to lighting apparatus field, relates in particular to a kind of LED bulb.
Background technology
At present, LED illumination has progressively become main flow illuminating product, and the use of LED bulb is also more and more universal; LED light fixture in use, must consider comprehensively by its radiator structure, and the lasting illuminating effect reliably of guarantee LED so further extends service life of LED light fixture; Structural limitations due to bulb, its radiator structure designs comparatively complicated, general, the space first half of the traditional cell-shell of meeting is set to transparent bulb case, Lower Half integral body is heat sink assembly, and so, bulb can reduce to some extent as the illuminating effect of spot light, the outward appearance that causes too greatly conventional bulb of radiator is complicated simultaneously, heaviness; And complicated structure makes traditional LED bulb assembling process complicated, waste time and energy.
Summary of the invention
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of LED bulb, and it has the feature of the assembling of being easy to, and same time radiator structure is more reliably light.
The utility model solves the technical scheme that its technical problem adopts: a kind of LED bulb, comprise heat conduction shell, and heat conduction shell one side connects lamp holder, and opposite side connects radiating subassembly and transparent bulb case;
In described heat conduction shell, it is cavity, cavity cross section is step shape, larger step hole wall is threaded connection transparent bulb case, less step hole wall is threaded connection radiator, described radiator comprises foot of radiator, heat conduction supporting column is installed on foot of radiator top, and heat conduction supporting column top is outwards arranged symmetrically with a plurality of LED substrates, and LED lamp pearl is installed on LED substrate;
Described LED substrate comprises three parts, is respectively horizontal-extending portion, and horizontal-extending portion end is rake, and the end of rake is the vertical portion that is parallel to heat conduction supporting column direction, and vertical portion end is free end;
Described foot of radiator inner hollow, is provided with LED power supply in it;
Described heat conduction shell outside is manufactured with radiating fin radially.
Further: the quantity of above-mentioned LED substrate is four.
Further: above-mentioned cell-shell is bullet shape.
LED bulb described in the utility model has the following advantages:
The utility model LED bulb, the critical piece of its radiator part is all arranged on transparent bulb case inside, therefore has more succinct light outward appearance; Heat sink assembly of the present utility model, transparent bulb case is all threaded connection and is assembled in heat conduction shell inside, so assembling process is very simple, time saving and energy saving; More excellent, the utility model is by becoming LED substrate manufacture the structure of a plurality of similar umbrella frame shape of dispersion, make between LED substrate, to there is the space being separated by, being convenient to a part of heat distributes to outside via transparent bulb case very smoothly, so, transparent bulb case not only has larger light-emitting area, also has larger area of dissipation, has increased radiating effect; Meanwhile, also have most heat finally by heat conduction shell, to be dissipated via foot of radiator by heating column, so, the utlity model has two cover cooling systems, can realize reliable heat radiation, there is larger light-emitting area simultaneously, easier package assembly.
