The utility model content
The purpose of this utility model is to improve the deficiencies in the prior art, provides a kind of applicable to room lighting, and penetrates light, the high brightness of dispersion shape, the LED energy-saving illumination bulb of low power consuming.
The technical solution of the utility model is achieved in that
This LED energy-saving illumination bulb comprises lamp socket, power drives, the lamp bowl, fin, lamp pearl pedestal and lamp bowl cover, in this lamp socket, settle this power drives, this lamp socket upper end is affixed with this lamp bowl bottom, described fin places on the inner bottom plating of this lamp bowl, cement in this lamp pearl base bottom by heat conductive silica gel in fin upper end and to make lamp pearl pedestal place lamp bowl the rim of a bowl portion, lamp pearl pedestal upper end is provided with the lamp pearl, it is connected with power drives in the lamp socket by lead, at least one lamp pearl is distributed on the lamp pearl pedestal, have on the lamp bowl cover and the corresponding hole of lamp pearl quantity, this hole and lamp pearl make this lamp bowl cover be fixed on the lamp bowl upper port accordingly, be provided with dielectric film between this lamp pearl pedestal upper end and lamp bowl cover, the position perforate of corresponding lamp pearl is exposed the lamp pearl on this dielectric film.
At the LED energy-saving illumination bulb described in this programme, its inner power drives can be to exchange to drive, and also can be DC driven, when power supply drives for exchanging, be a kind of the 220V alternating current to be become the galvanic constant-current source of 10-11V, electric current distributed to lamp pearl of described each series connection; When its inner power drives is DC driven, be a kind of under the DC current of 12V the constant-current source of stabling current, or on circuit series connection one divider resistance, be a kind of under the DC current of 12V the constant-current source of shunting voltage.
The utility model has the advantages that: this LED energy-saving illumination bulb structure is simple, exquisite, the lamp pearl places lamp bowl upper port place, the luminous angle of lamp pearl is maximum and greater than 180 degree, can realize penetrating light like this is dispersion shape, thereby reach indoor or the compartment in many places light is arranged, and realize the illuminating effect of indoor common bulb, because what lamp pearl pedestal adopted is LED lamp pearl, do not contain ultraviolet ray and infrared ray and the more power saving of more existing electricity-saving lamp in the LED spectrum, the power consumption of bulb is lower than general electricity-saving lamp, and 3W's is but also bright than the electricity-saving lamp of 10W.
The utility model is described in further detail below by accompanying drawing.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of the LED energy-saving illumination bulb that provides of the utility model;
Fig. 2 is the decomposition texture schematic diagram of the LED energy-saving illumination bulb that provides of the utility model;
Fig. 3 is the fin perspective view of the LED energy-saving illumination bulb that provides of the utility model;
The specific embodiment
As Fig. 1,2,3, shown in 4, the LED energy-saving illumination bulb that the utility model provides comprises lamp socket 1, power drives 2, lamp bowl 3, fin 4, aluminum lamp pearl pedestal 5 and lamp bowl cover 6, in lamp socket 1, settle power drives 2, lamp socket 1 upper end is connected by screw with lamp bowl 3 bottoms, fin 4 places on the inner bottom plating of lamp bowl 3, cement in lamp pearl pedestal 5 bottoms by heat conductive silica gel in fin 4 upper ends and to make lamp pearl pedestal 5 place lamp bowl 3 the rim of a bowl portions, the lamp pearl of lamp pearl pedestal 5 upper ends is connected by the power drives 2 in lead and the lamp socket 1, in the present embodiment, three lamp pearls 7 are set on lamp pearl pedestal 5,120 degree are distributed on the lamp pearl pedestal 5 being at interval on the circumference for it, have three circular holes that expose the lamp pearl on the lamp bowl cover 6 on the position of corresponding lamp pearl, make that the lamp pearl can expose when lamp bowl cover 6 was fixed on lamp bowl 3 upper port from circular hole, between lamp pearl pedestal 5 upper ends and lamp bowl cover 6, be provided with dielectric film, be heat-resisting wallpaper for example, perforate is exposed lamp pearl 7 on the wallpaper.
The operation principle and the feature of LED energy-saving illumination bulb:
