Description
Technical field
The present invention relates to lighting field, more particularly, to a kind of high heat dispersion, the led corn lamp of big lighting angle.
Background technology
Led corn lamp is one kind of LED lamp, belongs to light source class, and 360 degree of cinctures are luminous, and its shape and lamp bead are distributed such as
Same corncob, referred to as led corn lamp.Because led corn lamp brightness is high, lighting angle is big, radiating effect is preferable, thus increasingly
It is widely used in multiple illumination occasions.
A kind of basic structure of existing led corn lamp can refer to the patent of Publication No. cn205579217u, and its structure is:
The radiator being connected with lamp holder including lamp holder, the LED light source being arranged on radiator；The structure of its radiator is: includes hollow
Cylinder body and the multiple even circumferentials distribution outwards integrally being extended out by body heat sink, on each heat sink
Even be provided with vertical bar shaped LED lamp plate, even on vertical bar shaped LED lamp plate set lampshade.
Above-mentioned radiator can adopt extrusion forming process, and one extrudes longer shape, needs to cut further according to length
Cut and form shorter lamp radiator, convenient for production, cost is relatively low.
But, due to being enclosed hollow circular cylinder in the middle of above-mentioned radiator, air can only be passed to two neighboring dissipating
It is impossible to pass through the cylinder of hollow in gap between hot plate, thus cross-ventilation cannot be realized；Radiator is having the one side of wind
Air reflection can be realized and realize heat flowing, then be difficult to air flow and it is also difficult to realize leeward in leeward one side
The radiating in face.
The increase of the drawbacks limit of above-mentioned radiator led corn lamp power is it is difficult to by related Safety Approval.That is, when
When led corn lamp power increases, heat cannot comparatively fast remove, and lead to led comparatively fast to produce light decay, have a strong impact on making of led
Use the life-span.
On the other hand, existing led corn lamp is general is only provided with LED light source in lamp body periphery and bottom, and its top does not have
It is provided with LED light source, and people always like truly 360 degree pursued as conventional tungsten bulb to light, and
Also truly 360 are really needed to light in some occasions, when such as turning led corn lamp around installation.
On the other hand, the mode each heat sink of existing led corn lamp being installed vertical bar shaped LED lamp plate is generally,
Draw-in groove is arranged on heat sink, vertical bar shaped LED lamp plate is in draw-in groove end insertion draw-in groove.Now, highly typically set must be than straight for draw-in groove
The circuit plate thickness of bar shaped LED lamp plate is slightly larger, and otherwise vertical bar shaped LED lamp plate is difficult to insert in draw-in groove；But draw-in groove height is more than
Circuit plate thickness, will make wiring board cannot be close to heat sink again, thus affecting the conduction of vertical bar shaped LED lamp plate heat.That is, existing
The setting having the heat sink of led corn lamp cannot meet requirement easy for installation and good heat conductive simultaneously.
Thus it is necessary to further be improved to the structure of existing led corn lamp.
