For making the object, technical solutions and advantages of the present invention clearly understand, below by accompanying drawing and embodiment, the present invention is further elaborated.But should be appreciated that, specific embodiment described herein, only in order to explain the present invention, is not limited to scope of the present invention.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present invention.
Consult Fig. 1 and Fig. 2, the embodiment of the present invention provides a kind of Multifunctional LED bulb, comprise lamp body 1, LED 2, dc source 3, PCB control panel 7, the interface 4 be connected with the external world and diffuser 5, interface 4 is located at the bottom of lamp body 1, diffuser 5 is located at the top of lamp body 1, LED 2, it is inner that dc source 3 and PCB control panel 7 are all located at lamp body 1, also comprise aluminium base 6, aluminium base 6 is located at the top open part of lamp body 1, diffuser 5 is located at the top of aluminium base 6, LED 2 is evenly distributed on the upper side of aluminium base 6, LED 2 is some pieces of paster LEDs, reduce the heat that LED 2 self produces, and paster LED can provide the lighting angle that scope is larger.
In an embodiment of the present invention, LED 2 is separated with lamp body 1 by the aluminium base 6 as carrier, the maintenance of person easy to use and replacing, avoid the situation having to when LED bulb does not work whole LED bulb to abandon, effectively reduce the use cost of LED bulb.
Particularly, PCB control panel 7 is located at the below of aluminium base 6, and the below of PCB control panel 7 is located at by dc source 3, and the output of dc source 3 is fixedly connected with lamp body 1, and interface 4 is located at the below of dc source 3.
Referring again to Fig. 3, PCB control panel 7 comprises power circuit block 71, gauge tap module 72 and the control circuit module 73 receiving extraneous analog signal, power circuit block 71 is connected with gauge tap module 72, control circuit module 73 is connected with gauge tap module 72, gauge tap module 72 is connected with LED 2, and dc source 3 is connected with gauge tap module 72 with power circuit block 71 respectively.
Embodiments of the invention have been converted the built-in power technology of LED lamp tube, in common LED bulb, set up dc source 3, and by the control of PCB control panel 7 pairs of LED 2 driving powers, make LED bulb have following functions:
One is when having external power supply, and driving LED lamp 2 throws light on the one hand, charges on the other hand to dc source 3;
Two is electric currents provided at external power supply when being not sufficient to driving LED lamp 2, using dc source 3 together as the driving power that driving LED lamp 2 throws light on;
Three is when not having external power supply, and LED 2 adopts direct current in dc source 3 as drive current.Now, LED 2 is without the need to being connected with dc source 3 by PCB control panel 7, as long as be linked to be path between LED 2 and dc source 3, LED bulb just can carry out illumination.
Further, lamp body 1 is the coniform of hollow, lamp body 1 comprises the conductive layer 11 being located at inner side and the heat dissipating layer 12 being located at outside, aluminium base 6, PCB control panel 7 and dc source 3 are all electrically connected with conductive layer 11, interface 4 and diffuser 5 are set in bottom and the top of heat dissipating layer 12 respectively, and medial surface and the conductive layer 11 of interface 4 are electrically connected.In this kind of structure, the radius at the top of lamp body 1 is greater than the radius bottom lamp body 1.
Embodiments of the invention adopt whole lamp body 1 as electric conductor, dc source 3 can be directly connected with LED 2 at an arbitrary position, only need to ensure that the output of dc source 3 contacts with conductive layer 11, thus not only greatly facilitate user and change dc source 3, but also decrease PCB control panel 7 and wire structures a large amount of between dc-battery and LED 2, syndeton even directly can be coated in the inner side of lamp body 1 by the producer, reduces the volume of PCB control panel 7 further.In this kind of structure, it is inner that PCB control panel 7 both can be fixed on lamp body 1, and now, dc source 3 is separated with lamp body 1 by the opening bottom lamp body 1; Also can be connected with conductive layer 11 by separable structure, now, dc source 3 is separated with lamp body 1 by the opening at lamp body 1 top.
