Description
Technical field
This utility model relates to printed-board technology field, is specifically related to a kind of modified form and has the road of great heat radiation effect
Lamp circuit board.
Background technology
Circuit board is a kind of circuit circuit board, and its surface is covered with circuit, meanwhile, by connection components and parts, whole
Circuit board operationally can produce heat, and along with the functional structure of circuit board becomes increasingly complex, its heat dissipation capacity is the most increasing.And
In street lamp field, typically all using high-powered LED lamp, the thermal resistance value of high-powered LED lamp just can directly affect circuit board
Often work i.e. service life, therefore need a kind of circuit board being capable of excellent secure heat dissipation effect badly.
In Chinese patent application prospectus CN205191343 U, the heating problem for street lamp circuit plate discloses one
The aluminum plate of kind of solar street light, including aluminum plate main body, described aluminum plate main body include successively refractory protection, line layer,
Insulating barrier, aluminum soleplate；Described refractory protection is provided with terminal hole, and described terminal hole is arranged in array；Described line layer is arranged
In insulating barrier front, the insulating barrier back side is covered with heat-conducting glue, and insulating barrier is by the front adhesion of heat-conducting glue with aluminum soleplate；Aluminum soleplate
It is semicircular raised line that the back side is provided with cross section；Described aluminum plate main body both sides are provided with installing hole, and aluminum plate main body is randomly distributed
The circuit having some louvres, described louvre to avoid line layer is arranged.This technology uses heat-conducting glue can reduce as far as possible absolutely
The thickness of edge layer, to reduce the insulating barrier impact on heat-conducting effect, simultaneously by arrange in aluminum plate main body louvre and
The aluminum soleplate back side arranges heat radiation raised line, carrys out increasing heat radiation area, improves radiating effect.But, the radiating effect of this technology is still deposited
Slow at radiating rate, radiating effect not significantly problem.
Summary of the invention
In order to solve the problem existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of modified form street lamp to use
Circuit board, by changing the hierarchical structure of circuit board, it is achieved large area, the effect of high efficiency and heat radiation.
The technical solution adopted in the utility model is: a kind of modified form street lamp circuit board, including substrate and aluminium sheet, described base
It is provided with some terminal holes and some louvres on plate, is provided with cushion block, described substrate and aluminium sheet between described substrate and aluminium sheet logical
Cross screw to fix；The upper surface of described substrate is provided with refractory protection, and the lower surface of described aluminium sheet is provided with heat radiation raised line；Institute
The inside stating terminal hole and louvre is covered each by the metal level of anti-oxidation, sulfuration.
Preferred version is, described cushion block is rubber blanket or ceramic blanket.
Preferred version is, described heat radiation raised line is set to the raised line that cross section is rectangle.
Preferred version is, the thickness of described cushion block is 0.5-1mm.
Preferred version is, the thickness of described refractory protection is 0.02-0.1mm.
The beneficial effects of the utility model are: simple in construction, arrange cushion block between substrate and aluminium sheet, in conjunction with aluminium sheet following table
The heat radiation raised line in face and the refractory protection of upper surface of base plate, increase the area of dissipation of circuit board, thus promote the heat radiation of circuit board
Speed.

Detailed description of the invention
With embodiment, the technical solution of the utility model is illustrated below in conjunction with the accompanying drawings.
With reference to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of modified form street lamp circuit board, including substrate 2 and aluminium sheet 6, described base
It is provided with some terminal holes 7 and some louvres 8 on plate 2, between described substrate 2 and aluminium sheet 6, is provided with cushion block 4, at cushion block
Under the support of 4, having certain gap between substrate 2 and aluminium sheet 6, this cushion block 4 is rubber blanket or ceramic blanket, and its thickness is
0.5-1mm.Described substrate 2 and aluminium sheet 6 are fixed by screw 3, easy to assembly.The upper surface of described substrate 2 is provided with heat-resisting
Protective layer 1, the thickness of refractory protection 1 is 0.02-0.1mm.The lower surface of described aluminium sheet 6 is provided with heat radiation raised line 5, heat radiation
Raised line 5 is set to the raised line that cross section is rectangle.This utility model simple in construction, arranges cushion block 4 between substrate 2 and aluminium sheet 6,
In conjunction with heat radiation raised line 5 and the refractory protection 1 of substrate 2 upper surface of aluminum 6 plate lower surface, increase the area of dissipation of circuit board,
Thus promote the radiating rate of circuit board.
Above-described embodiment is only that of the present utility model ultimate principle, principal character and advantage have been shown and described.The skill of the industry
Art personnel are it should be appreciated that this utility model is not restricted to the described embodiments, and described in above-described embodiment and description is to say
Bright principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has various change
