Description

A kind of LED bulb and light fixture with fan

Technical field

The utility model relates to a kind of LED lighting apparatus with fan, relates in particular to a kind of LED bulb and light fixture of band fan of special air circulation direction.

Background technology

The LED illumination is as the part of low-carbon (LC) life, and its good low-power, lower calorific value performance have replaced the lamp of other types gradually.LED illumination mainly is to comprise LED light fixture and LED bulb, and the LED light fixture needs original lamp socket integral body to replace, and the LED bulb can be directly installed on original lamp socket, relatively latter's alternative costs lower, be easy to promote.The LED bulb material that occurs on the market is based on metal, pottery or heat radiation plastics, and it mainly dispels the heat by heat radiation, and heat dispersion is limited.LED bulb than the band fan of small part is also arranged, but at present with the LED bulb of fan mainly the form in the light fixture side design into/exhaust vent, disclosed as China national Department of Intellectual Property on February 10th, 2010, the patent No. is CN200920135445.5, publication number is the high-power LED lamp structure that has fan of CN201401764, it adopts the side air inlet complex structure, and can't reach dustproof requirement owing to weight effect dust easily accumulates in the bulb inner bottom part.

The utility model content

The main technical problems to be solved in the utility model is, a kind of LED bulb and light fixture with fan is provided, and has good dustproof effect is arranged.

For solving the problems of the technologies described above, the utility model provides a kind of LED bulb with fan, comprise the bulb shell that has interface, the lamp plate that is arranged on the bulb shell bottom surface, be arranged on the power supply and blower in the bulb shell, described power supply connects with fan, lamp plate and interface circuit respectively.In described bulb shell bottom surface, be provided with air vent between lamp plate and the bulb shell.In the bulb shell bottom surface air vent is set, makes dust brush under the effect and can drop, play dustproof effect to the bottom at gravity and fan.Reduce space requirement simultaneously, make the LED bulb have better replaceability the sidewall of existing lamp socket.

Described air vent comprises that gas circuit is communicated with and opposite first air vent and second air vent of turnover airflow direction, and described fan is connected in the gas circuit between first air vent and second air vent.Can effectively drive wind path from fan, air is circulated between first air vent and second air vent, dispel the heat; Certainly, first air vent and second air vent are respectively according to the air stream drives direction of fan and are air inlet and air outlet.

Described air vent be arranged on one with drain pan that the bulb shell bottom surface is connected on, described lamp plate is arranged on the drain pan middle part.Drain pan the installation that can make things convenient for LED bulb internal structure is set, also made things convenient for the setting of radiator structure, compact overall structure, die sinking cost are reduced; Lamp plate is arranged on the drain pan middle part, has made things convenient for the setting of air vent, and makes the area of dissipation maximization.

Described LED bulb also includes the dividing plate of a tubulose; Be divided into two zones with air vent between the bulb shell by cooperating at described lamp plate, be respectively the zone of the close lamp plate periphery that described first air vent is set and the zone on the close bulb shell base of described second air vent is set with dividing plate.The employing of dividing plate makes simple in structure, and effectively will prevent to leak out at the unidirectional wind path of the inner formation of bulb, improves the fan radiating efficiency.

Described dividing plate is fixed on the drain pan, and described fan diameter and baffle dimensions are adaptive.The structure that dividing plate and drain pan or fan are fixing is in order to improve itself and the quality of fit of air vent, and reduces the number of spare parts when assembling.

Described drain pan also includes the upwardly extending helical form plate body from the bulb shell bottom surface; Described first air vent and second group of air vent are divided into unit, a plurality of independently hole by a plurality of helical form plate bodys.But helical form plate body uniform air flow, and can increase the contact area of air-flow and bulb, improve radiating efficiency.

Described lamp plate is the circuit board that is provided with the LED lamp holder, also is provided with the lens that block lamp plate on drain pan.The setting of scioptics and kind are selected, and can easily the LED bulb be arranged to shot-light or bulb lamp.

Described bulb shell is with after interface is connected, and bulb shell other parts except that the bottom surface constitute enclosed construction.So only in the bulb shell bottom surface air vent is set, the turnover air-flow passes by the bottom surface, dust can be dropped, and the dust that LED bulb itself drops to the bulb outside has the effect of blocking downwards.

The flabellum cross section of described fan is camber line shape (fluid is floating wing).The physical characteristic of this flabellum makes the bulb can be at low noise under the negative pressure, and the fan setting has also improved the service life of bulb

A kind of light fixture includes a lamp socket, is connected with the LED bulb of aforesaid band fan on the described lamp socket.Because LED bulb self has just adopted heat radiation and dustproof structure, thereby can dwindle this light fixture volume greatly, reduces cost.

Described lamp socket be provided with the LED bulb on the adaptive socket of interface, to make things convenient for the replacing of bulb or lamp socket.

The beneficial effects of the utility model are: adopt technique scheme of the present utility model, in the bulb shell bottom surface air vent is set, make dust brush under the effect and can drop to the bottom at gravity and fan, play dustproof effect; Reduce space requirement and bulb compact overall structure simultaneously, make the LED bulb have better replaceability the sidewall of existing lamp socket.Because LED bulb self just adopted heat radiation and dustproof structure, thereby can dwindle this light fixture volume greatly, reduce cost, guarantee service life of bulb.
