Description
Technical field
The utility model is related 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 circular luminous, and its shape and lamp bead distribution are such as
Same corn ear, 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 various 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：
Including radiator, the LED light source being arranged on radiator that lamp holder and lamp holder are connected；The structure of its radiator is：Including hollow
Cylinder body and the heat sink that is distributed of multiple even circumferentials for outwards integrally being extended out by body, on each heat sink
It is even to be provided with vertical bar shaped LED lamp panel, it is even in vertical bar shaped LED lamp panel to set lampshade.
Above-mentioned radiator can use extrusion forming process, and one extrudes shape more long, need to cut further according to length
Cut to 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 scattered
In gap between hot plate, it is impossible to through hollow cylinder, thus cross-ventilation cannot be realized；Radiator is having the one side of wind
Can realize that air reflection realizes that heat flows, then be difficult to air flow in leeward one side, and it is also difficult to realize leeward
The radiating in face.
The defect of above-mentioned radiator limits the increase of LED corn lamp power, it is difficult to by related Safety Approval.That is, when
When LED corn lamp power increases, heat cannot be removed comparatively fast, cause LED comparatively fast to produce light decay, have a strong impact on making for 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
LED light source is provided with, and truly 360 degree that people always like pursuing as conventional tungsten bulb light, and
Truly 360 are also needed to light really in some occasions, when such as turning LED corn lamp around installation.
On the other hand, the mode that vertical bar shaped LED lamp panel is installed on each heat sink of existing LED corn lamp is generally,
Draw-in groove is set on heat sink, and vertical bar shaped LED lamp panel is from draw-in groove end insertion draw-in groove.Now, typically set must be than straight for draw-in groove height
The circuit plate thickness of bar-shaped LED lamp plate is slightly larger, and otherwise vertical bar shaped LED lamp panel is difficult in insertion draw-in groove；But draw-in groove is highly more than
Circuit plate thickness, and will cause that wiring board cannot be close to heat sink, so as to influence the conduction of vertical bar shaped LED lamp panel heat.That is, it is existing
The setting for heat sink for having LED corn lamp cannot be while meet easy for installation and good heat conductive requirement.
Thus, it is necessary to the structure to existing LED corn lamp is further improved.
