Abstract
The utility model discloses an LED lamp bulb which comprises a lamp cap, a transparent housing and a control circuit. An LED light source assembly is arranged in the transparent housing; a PCB bus board is longitudinally arranged in the transparent housing; a plurality of PCB branch boards are longitudinally arranged on the PCB bus board; a plurality of LEDs are uniformly arranged around the PCB branch boards; and each LED is opposite to the PCB bus board. The utility model has the advantages that the PCB branch boards are longitudinally arranged on the PCB bus board; the LEDs are uniformly arranged around the PCB branch boards; each LED is opposite to the PCB bus board; the PCB branch boards and the PCB bus board perform dual functions of structural connection and electrical conduction; more LEDs are mounted in a smaller space of the structure; and meanwhile, due to the directions of the side surfaces of the LEDs, the light rays of the LEDs can basically cover the area of the transparent housing, so that the lighting shadow area of an LED lamp is reduced.
Description
Technical field
The utility model relates to a kind of illuminating lamp, especially relates to a kind of LED bulb.
Background technology
Traditional incandescent light bulb power consumption is big, and brightness is low, and service life is short.And there is the secondary pollution of production and post processing again in energy-saving fluorescent lamp cold-starting difficulty.Occurred a kind of LED bulb at present, it has advantages such as environmental protection, energy-conservation and life-span be long, becomes the main direction of following lighting field.China Patent No. is that 200720173645.0 utility model patent discloses a kind of LED bulb, comprise that the aluminium base front is equiped with the led light source array, array of source is made up of many low-power LED light sources, its solved high-power LED light source in use heat concentrate, drawback such as be difficult for distributing.But the problem of its existence is: a plurality of led light sources are arranged in one plane, and its light that sends is mainly concentrated the forward face of led light source, have bigger lighting blind zone at the back side of led light source.
Summary of the invention
Technical problem to be solved in the utility model provides the less LED bulb of a kind of lighting blind zone.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of LED bulb, comprise lamp holder, transparent casing and control circuit, be provided with the led light source assembly in the described transparent casing, light source assembly comprises pcb bus plate, a plurality of PCB branch line plate and is arranged on a plurality of LED on the PCB branch line plate, described pcb bus plate vertically is arranged in the transparent casing, described a plurality of PCB branch line plate vertically is arranged on the described pcb bus plate, a plurality of LED evenly be arranged on PCB branch line plate around, described each LED towards deviating from the pcb bus plate.
The bottom of described Transparent lamp shade is provided with the support with column type cavity, erection column with square opening is set on the described support, the plane of structure of described pcb bus plate is long-pending for square, pcb bus plate bottom is inserted and is fixed in the described erection column, and described control circuit board is seated in the column type cavity of support.
Described transparent casing comprises upper encloser and lower encioser, and described upper encloser and described lower encioser bond together, and the diameter at described bonding position is greater than other positions of transparent casing.
The column type cavity of described support communicates with the cavity of lamp holder, and the components and parts on the described control circuit board are placed within the cavity of the column type cavity of described support and lamp holder.
Described PCB branch line plate is round
Compared with prior art, advantage of the present utility model is that a plurality of PCB branch line plates vertically are arranged on the pcb bus plate, a plurality of LED evenly be arranged on PCB branch line plate around, each LED towards deviating from the pcb bus plate.PCB branch line plate plays the dual-use function that structure is connected and electrically conducts with the pcb bus plate, and this structure can be installed more LED in less space, increases the brightness of illumination of LED lamp.Simultaneously since the side of LED towards, make the light of LED can cover the transparent casing region substantially, the LED bulb light of comparing traditional structure mainly concentrates on the upper area of case, has reduced the lighting blind zone of LED lamp.
The top of support is used for fixing light source assembly, and the interior control circuit board of placing in the cavity of support makes the internal structure of LED bulb compact more reliable.
The transparent casing of existing LED bulb to be shaped as two little broad in the middle because the shared space of light source assembly is bigger, the light source assembly of packing into after the maximum gauge punishment of transparent casing is cut carries out bonding again, has solved pack into the problem of difficulty of light source assembly.
Components and parts on the control circuit board are placed within the cavity of the column type cavity of support and lamp holder.Utilize the space in the lamp holder preferably, saved the inner space of transparent casing.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
A kind of LED bulb, comprise lamp holder 1, transparent casing 2 and control circuit, be provided with the led light source assembly in the transparent casing 2, light source assembly comprises pcb bus plate 3, a plurality of PCB branch line plate 4 and is arranged on a plurality of LED on the PCB branch line plate, the pcb bus plate vertically is arranged in the transparent casing 2, a plurality of PCB branch line plates 4 vertically are arranged on the pcb bus plate 3, a plurality of LED evenly be arranged on PCB branch line plate 4 around, each LED towards deviating from pcb bus plate 3.The bottom of Transparent lamp shade 2 is provided with the support 5 with column type cavity, erection column 6 with square opening is set on the support 5, the plane of structure of pcb bus plate 3 is long-pending for square, and pcb bus plate 3 bottoms are inserted and are fixed in the erection column 6, and control circuit board 7 is seated in the column type cavity of support 5.Transparent casing 2 comprises upper encloser 21 and lower encioser 22, and upper encloser 21 and lower encioser 22 bond together, and the diameter at bonding position 23 is greater than other positions of transparent casing 2.The column type cavity of support 5 communicates with the cavity of lamp holder 1, and the components and parts on the control circuit board 7 are placed within the cavity of the column type cavity of support and lamp holder.PCB branch line plate 4 is round.Control circuit adopts conventional on-off circuit.
