Description

With the light emitting diode is omnidirectional's bulb of light source

Technical field

The utility model relates to a kind of bulb, and relating in particular to a kind of is the bulb that light source, light emission direction are approached omnidirectional in fact with the light emitting diode.

Background technology

(light emitting diode is not LED) because power saving, generate heat, be widely used in the various lighting fields with factors such as the life-span are long for light emitting diode.But light emitting diode is because of structural factors such as encapsulation, and the light of being launched normally is limited in the certain limit, also therefore is extensive use of the lighting device that the light emitting diode person belongs to porjection type more, for example flashlight, car light, street lamp etc. at present.Relative, the most frequently used incandescent lamp bulb in the resident family is to utilize the fuel factor of filament and luminous at present, its light emission direction is omnidirectional (omnidirectional).Therefore, in the illumination of resident family, use light emitting diode to replace traditional filament, certainly will will solve the circumscribed problem of light emitting diode light transmit direction.

The utility model content

Technical problem underlying to be solved in the utility model is, overcome the circumscribed problem that existing light emitting diode light transmit direction exists, and provide a kind of is omnidirectional's bulb of light source with the light emitting diode, can effectively increase illuminance, avoids overlapping uneconomical of range of exposures.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of is omnidirectional's bulb of light source with the light emitting diode, it is characterized in that, comprises at least: the lamp body of a printing opacity; One end body is an end of being located at this lamp body, and its outside is provided with screw thread and electrical equipment contact, to screw in a tube face and to set up an electric binding with this tube face; One support column, this end body extends into this lamp body inside certainly; One lamp panel is to be positioned at the inner also string of this lamp body to be located on this support column, and its periphery is to be interval with several opposing each other light emitting diodes, and this lamp panel has at least one circuit and starts those light emitting diodes with power supply; Wherein, this support column has conductive structure, and this conductive structure will be held the electric binding of body and this and be connected with this circuit of each lamp panel.

Aforesaid is omnidirectional's bulb of light source with the light emitting diode, and wherein lamp panel has two at least.

Aforesaid is omnidirectional's bulb of light source with the light emitting diode, and the light emitting diode of wherein adjacent described two lamp panels disposes with interlace mode.

The beneficial effects of the utility model are, can effectively increase illuminance, avoid overlapping uneconomical of range of exposures.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 a be of the present utility model be the schematic side view of an embodiment of omnidirectional's bulb of light source with the light emitting diode.

Fig. 1 b be of the present utility model with the light emitting diode be light source omnidirectional's bulb lamp panel overlook enlarged diagram.

Fig. 2 be of the present utility model be the schematic side view of another embodiment of omnidirectional's bulb of light source with the light emitting diode.

The number in the figure explanation:

10 lamp bodies, 20 end bodies

21 screw threads, 30 lamp panels

31 light emitting diodes, 40 support columns

The specific embodiment

As shown in Figure 1a, the bulb that the utility model proposed comprises the lamp body 10 of a light-permeable at least.This lamp body 10 is a hollow, and its profile can be the spherical shape of conventional incandescent bulb or egg type as shown in the figure or other suitable shape.

One end of this lamp body 10 is provided with an end body 20 that has screw thread 21, can screw in conventional incandescent bulb seat (not shown).This end body 20 has two electric terminals (not shown in the figures, common for screw thread 21 itself, another is located at end body 20 bottoms) usually, is connected with two utmost points of the voltage that provided with tube face.End body 20 inside can be provided with rectification, voltage stabilizing or other suitable circuit (for example circuit overcurrent protection etc.), and for the personage of affiliated technical field, these circuit should be implemented easily, therefore do not draw in the drawings.

This bulb further comprises an at least one lamp panel 30 and a support column 40.Lamp panel 30 can be circle, polygon or other shape as shown in the figure.The periphery of lamp panel 30 is to be interval with two or more a plurality of opposing each other light emitting diode 31.The front (exiting surface) that so-called " opposing each other " is meant those light emitting diodes 31 towards the centrifugal direction of lamp panel 30 and the back side toward each other.Please further consult (dotted line is wherein represented the transmitting boundary of light) shown in Fig. 1 b, the common formation of emission light of these light emitting diodes 31 almost is the range of exposures of omnidirectional as can be seen, can solve the circumscribed problem of light emitting diode light transmit direction.Therefore, light emitting diode 31 numbers that each lamp panel 30 adopts are higher, it is littler at interval, and then the omni-directional of this bulb irradiation scope is higher, brightness is also stronger.Please consult Fig. 2 simultaneously.If will further promote the brightness of this bulb, can adopt more than one lamp panel 30.

As shown in Figure 2, this support column 40 is to extend into this lamp body 10 inside from this end body 20, and at least two lamp panels 30 are connected in series at interval.In the embodiment that uses at least two lamp panels 30, in order to save the usage quantity of light emitting diode 31, can make the light emitting diode 31 of adjacent two lamp panels 30 dispose (that is on the vertical direction with interlace mode, two adjacent light emitting diodes 31 are not to be positioned at same position), as shown in Figure 2, reach the even distribution of light emitting diode 31, can effectively increase illuminance, avoid overlapping uneconomical of range of exposures at solid space.

Support column 40 also has the effect of electrical conductivity except the effect that fixing lamp panel 30 is arranged.Each lamp panel 30 has at least one circuit and starts light emitting diode 31 on it with power supply.This support column 40 also has conductive structure, is connected with the circuit of each lamp panel 30 with the circuit that will hold body 20.For the personage of affiliated technical field, described circuit and conductive structure should be implemented easily, therefore do not draw in the drawings.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
