Abstract
The utility model discloses a kind of LED street lamp lamp holder employment shape Radiator, belong to street lighting technical field, the mainly heat dissipation bottom sheet with installing hole, being fixed with some herringbones heat radiation guide pillar in described heat dissipation bottom sheet, described herringbone heat radiation guide pillar is formed by three identical radiating fins are uniform around the center of circle.The utility model smart structural design, three radiating fins are uniformly distributed around the center of circle, radiating fin area of dissipation is big and every radiating fin dispels the heat towards different spaces direction, area of dissipation is big, good heat dissipation effect, structure design is simple, and processing technology is also easy, practical value is very high, can be widely applied to street lighting technical field.
Description
Technical field
The utility model belongs to street lighting technical field, specifically, particularly relates to a kind of LED street lamp lamp
Head employment shape Radiator.
Background technology
The duty of LED and heat dissipation design are not only directly connected to the actual luminous efficiency of LED, are also related to reality
Border service life.If its photoelectric transformation efficiency of the LED of 1 10W is 20%, then the electric energy of 8W is had to be converted into
Heat energy, if being not added with cooling measure, then the junction temperature of LED can rise rapidly, when exceeding maximum allowable temperature
When, LED chip can be damaged because of overheated.The quantity of heat production of high-powered LED lamp is very many, and this requires high-power
LED must have reasonable and effective radiator structure, and rational radiator structure can be effectively by LED chip
The heat producing is transmitted on the shell of lamp, it is also possible to increases the contact surface area with air, so increases simultaneously
Add heat transfer and the heat convection effect of lamp body.The cooling requirements of high-powered LED lamp to be met, is necessary for making
With fin, and high efficiency fin should meet, and heat absorption is fast, thermal resistance is little and fast three basic demands of reducing phlegm and internal heat.
Now presenting multiple radiator on the market, but the design of traditional heat sinks structure being unreasonable, the design of good heat dissipation is complicated,
Processing technology is loaded down with trivial details；Structure design is simple, and the easy radiating effect of processing technology is poor again, is difficult to accomplish satisfactory to both parties
It is beautiful.
Content of the invention
The utility model discloses a kind of LED street lamp lamp holder employment shape Radiator, be used for solving traditional heat-dissipating
Device design is unreasonable, radiator otherwise design is complicated otherwise the problem of heat dispersion difference.
The utility model is achieved through the following technical solutions:
A kind of LED street lamp lamp holder employment shape Radiator, including with the heat dissipation bottom sheet of installing hole, described scattered
Being fixed with some herringbones heat radiation guide pillar on hot egative film, described herringbone heat radiation guide pillar is by three identical heat radiations
Fin is uniform around the center of circle to be formed.
Preferably, described radiating fin uses electric welding or mould process to be combined into heat radiation guide pillar.
Preferably, described heat radiation guide pillar is in a row evenly distributed in heat dissipation bottom sheet in column..
Compared with prior art, the beneficial effects of the utility model are:
Three radiating fins are uniformly distributed by the utility model smart structural design around the center of circle, and radiating fin dissipates
Hot side amasss big and every radiating fin and dispels the heat towards different spaces direction, and area of dissipation is big, good heat dissipation effect,
Structure design is simple, and processing technology is also easy, and practical value is very high, can be widely applied to street lighting technology
Field.
Brief description
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model heat radiation guide pillar structure schematic diagram.
In figure: 1. installing hole；2. heat dissipation bottom sheet；3. dispel the heat guide pillar；4. radiating fin.
Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is further illustrated:
A kind of LED street lamp lamp holder employment shape Radiator, including with the heat dissipation bottom sheet 2 of installing hole 1, described
Being fixed with some herringbones heat radiation guide pillar 3 in heat dissipation bottom sheet 2, described herringbone heat radiation guide pillar 3 is by three phases
Form with radiating fin 4 is uniform around the center of circle.
Described radiating fin 4 uses electric welding or mould process to be combined into heat radiation guide pillar 3.
Described heat radiation guide pillar 3 is in a row evenly distributed in heat dissipation bottom sheet 2 in column.
The utility model includes the heat dissipation bottom sheet 2 with installing hole 1, if being fixed with in described heat dissipation bottom sheet 2
Dry herringbone heat radiation guide pillar 3, each heat radiation guide pillar 3 be by three identical radiating fins 4 uniform around the center of circle and
Become, use electric welding or mould process to constitute between radiating fin overall.Described heat radiation guide pillar 3 is arranged as
Row are evenly distributed in heat dissipation bottom sheet 2.The utility model smart structural design, by three radiating fins around circle
The heart is uniformly distributed, and radiating fin area of dissipation is big and every radiating fin dispels the heat towards different spaces direction, dissipates
Thermal effect is good, and structure design is simple, and processing technology is also easy, and practical value is very high, can be widely applied to road
Lamp lighting technical field.
In sum, preferred embodiment only of the present utility model, is not used for limiting the utility model
The scope implemented, all according to the shape described in the utility model right, construction, feature and spirit institute
For impartial change with modify, all should be included in right of the present utility model.
