Abstract
The utility model discloses a light emitting diode (LED) lamp bulb which comprises a lamp holder, an inverted cone lamp cup and a hemispherical glass cover, wherein the lower end of the inverted cone lamp cup is connected with the lamp holder, and the hemispherical glass cover is connected with the upper end of the inverted cone lamp cup. The LED lamp bulb is characterized by further comprising a lamp pole with heat dissipation effect, the lamp pole is installed in the inverted cone lamp cup, the lower end of the lamp pole is connected with the lamp holder in a threaded mode, the upper end of the lamp pole is provided with a lamp panel, and the lamp panel is provided with a lamp bead. The lamp pole id further provided with a direct-current electrical source, an input end of the direct-current electrical source is connected with the lamp holder in an electric mode. An output end of the direct-current electrical source is connected with the lamp bead on the lamp panel in an electric mode. The LED lamp bulb has the advantages that due to the fact that the LED lamp bulb directly uses the lamp bead to dissipate the heat, a metal shell body which is used for dissipating the heat is not needed, the weight of the LED lamp bulb is reduced, and the LED lamp bulb is more artistic in shape at the same time.
Description
Technical field
The utility model relates to a kind of LED light fixture, particularly a kind of LED bulb.
Background technology
Existing illuminating lamp mainly is to adopt fluorescent lamp, electricity-saving lamp as illuminator, and the daylight lamp energy-saving effect is limited, and electricity-saving lamp has certain power savings advantages for fluorescent lamp, but still has the space of further raising.Along with the extensive use of LED lamp, the LED bulb has appearred now, and still existing LED bulb normal operation metal shell is as heat radiation, and the result causes LED bulb weight heavier.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of weight lighter LED bulb for the existing problem of existing LED bulb
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of LED bulb, comprise lamp holder, back taper Lamp cup and hemispheric cloche, the lower end of described back taper Lamp cup is connected with described lamp holder, described cloche is connected with back taper Lamp cup upper end, it is characterized in that, the lamppost that also comprises together thermolysis, described lamppost are arranged in described back taper Lamp cup; The lower end of described lamppost is connected with cap screw thread, in the upper end of lamppost lamp plate is installed, and is furnished with the lamp pearl on the lamp plate; In addition in described lamppost dc source is installed, the input of described dc source is electrically connected with described lamp holder, and the output of dc source is electrically connected with lamp pearl on the lamp plate.
The utility model has the advantage of: owing to directly adopting the lamp pearl to dispel the heat, not at the needs metal shell as heat radiation, reduced the weight of whole LED bulb, profile is more attractive in appearance simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of LED bulb of the utility model.
Fig. 2 is the axial section internal structure schematic diagram of a kind of LED bulb of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As depicted in figs. 1 and 2, a kind of LED bulb, comprise lamp holder 30, back taper Lamp cup 20 and hemispheric cloche 10, the lower end of back taper Lamp cup 20 is connected with lamp holder 30, cloche 10 is connected with back taper Lamp cup 20 upper ends, it also comprises the lamppost 14 of together thermolysis, and lamppost 14 is arranged in back taper Lamp cup 20; The lower end of lamppost 14 is threaded with lamp holder 30, in the upper end of lamppost 14 lamp plate 11 is installed, and is furnished with lamp pearl 12 on the lamp plate 11; In addition dc source 13 is installed in lamppost 14, the input of dc source 13 is electrically connected with lamp holder 30, and output is electrically connected with lamp pearl 12 on the lamp plate 11.
Only need lamp holder 30 spirals are screwed into lamp socket, plugged, bulb just can be sent out the warm white light that the seller is comfortable and the brightness highly energy-consuming is low.Operating ambient temperature of the present utility model is-20～40 ℃, condition of storage-20～85 ℃, operating frequency 50/60Hz, rated voltage AC100-240V, input current 30-70mA, power consumption 6.5 ± 0.3W, luminous flux 500 ± 10%LM, power factor 0.5, lamp pearl 12 quantity are 6, colour rendering index 〉=70CRI, 150 ° of lighting angles, lamp body surface temperature≤60 ℃.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
