Description
Technical field
The utility model relates to LED illumination lamp field, is specifically related to a kind of LEDbulb lamp.
Background technology
LEDbulb lamp directly replaces a kind of preferred version of conventional bulb, itself and conventional bulb volume and specification basically identical, but the volume of LEDbulb lamp is relative to much little LED street lamp lamp holder, be therefore undoubtedly a very troublesome thing for LED bubble lamp arranges LED direct current driving power supply; The LEDbulb lamp that tradition possesses LED direct current driving power supply all has complex structure, and cost is high, flimsy defect.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, and provide a kind of AC to exchange without driving bulb lamp, it is directly powered by civil power, does not need LED direct current driving power supply, simple and reliable for structure, good heat dissipation, and illumination effect is good.
The utility model solves the technical scheme that its technical problem adopts: a kind of AC exchanges without driving bulb lamp, comprises lamp holder, the Lamp cup be connected with cap screw thread, LED lamp bead, and covers at the lampshade outside LED lamp bead;
LED lamp bead is welded on aluminium base, and the pin of LED lamp bead is corresponding with the output of the non-transformer LED drive chip be welded on aluminium base to be electrically connected, and the input of non-transformer LED drive chip is corresponding with the binding post of lamp holder to be electrically connected; The outer surface of lampshade is sphere curved surface;
Also comprise connector, lamp holder is connected with the radiating fin be wrapped in outside Lamp cup by connector, and radiating fin offers air vent;
Described radiating fin fixedly mounts described aluminium base, and the bottom of described lampshade is fixed on radiating fin top equally;
Described cover surface coating layer of fluorescent powder;
Dispersed in described lampshade have fluorescent material.
As a kind of preferred structure of the utility model radiating fin, the width of above-mentioned radiating fin reduces from top to bottom gradually.
As the preferred detailed description of the invention of one, described lamp holder is connected with non-transformer LED drive chip by wire.
A kind of AC described in the utility model exchanges and has the following advantages without drive ball bubble lamp:
The utility model does not need power supply, and direct AC exchanges input, comprises lamp holder, the Lamp cup be connected with cap screw thread, LED lamp bead, and covers at the lampshade outside LED lamp bead; LED lamp bead is welded on aluminium base, and the pin of LED lamp bead is corresponding with the output of the non-transformer LED drive chip be welded on aluminium base to be electrically connected, and the input of non-transformer LED drive chip is corresponding with the binding post of lamp holder to be electrically connected; The outer surface of lampshade is sphere curved surface; The utility model AC exchanges without driving bulb lamp not need to use traditional LED drive power, and LED lamp bead directly can connect civil power through non-transformer LED drive chip, has cost low, and production technology is simple, the feature that efficiency is high;
The utility model being provided with has the radiating fin of air vent, considerably increases radiating effect, makes the working environment of whole bulb more stable; Meanwhile, the utility model is provided with fluorescent material at lampshade outer surface and inside, makes lighting effect (quality white light) more stable.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model detailed description of the invention is described:
Fig. 1 shows a kind of detailed description of the invention of the present utility model, and as shown in the figure, a kind of AC of the utility model exchanges without driving bulb lamp, it does not need power supply, and direct AC exchanges input, comprises lamp holder 1, the Lamp cup be connected with lamp holder 1 threaded engagement, LED lamp bead 7, and cover at the lampshade 8 outside LED lamp bead;
LED lamp bead 7 is welded on aluminium base 5, and the pin of LED lamp bead 7 is corresponding with the output of the non-transformer LED drive chip 6 be welded on aluminium base to be electrically connected, and the input of non-transformer LED drive chip 6 is corresponding with the binding post of lamp holder 1 to be electrically connected; The outer surface of lampshade 8 is sphere curved surface;
The utility model AC exchanges without driving bulb lamp not need to use traditional LED drive power, and LED lamp bead directly can connect civil power through non-transformer LED drive chip, has cost low, and production technology is simple, the feature that efficiency is high.
By reference to the accompanying drawings the utility model preferred embodiment is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Do not depart from design of the present utility model and scope can make many other and change and remodeling.
Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
