Abstract
The utility model relates to a high heat dissipation type circuit board for LED. The high heat dissipation type circuit board comprises a circuit board body. Two parallel metal electrodes are printed on a plane of the circuit board body, at least one separated pit is formed between the two electrodes, and an LED lamp is arranged in the pit; a through hole is formed at the bottom of the pit on the circuit board body; the diameter of the excircle of the through hole is smaller than that of the incircle of the pit. According to the technical scheme, the problem that cooling effect of the LED lamp is influenced due to unexpected conductivity of the circuit board is avoided.
Description
Technical field
The utility model belongs to LED field, refers to especially a kind of heat dissipation type high circuit board for fixed L ED light pearl.
Background technology
LED developed so far from nineteen sixties, and its application has expanded many fields to.LED is mainly critical piece by Light-Emitting Diode, and it utilizes the unidirectional powered of semiconductor P-N knot and realizes luminous.In photoelectric conversion in LED, have heat generation, decline along with the rising of temperature and the characteristic of LED is luminous efficiency.In the prior art, in order to guarantee the efficiency of LED, prevent excess Temperature, all adopt the mode that radiating element dispels the heat that installs additional.By statistics, in LED application, radiating element accounts between the 5%-7% of totle drilling cost.
The advantage of LED is can reach 60000-100000 hour its service life, and the service life of common fluorescent lamp or electricity-saving lamp is conventionally between 6000-10000 hour.But in actual applications, LED cannot realize long clear superiority, particularly high-power LED lamp of its life-span, its main cause is that heat radiation is insufficient, and too high temperature can have influence on luminous intensity and the life-span of LED.
What the circuit board of existing fixed L ED light pearl all adopted is on planar circuit board, to be printed with two flat coppers or aluminium electrode, and LED lamp pearl protrudes from circuit board.The circuit board now using, in order to guarantee certain insulating properties, just has a certain impact aspect heat dispersion.Now also there is technology to propose, be provided with a groove at two electrode mid portions, LED lamp pearl is arranged in groove, improve heat dispersion by the thickness that reduces circuit board, but this technical scheme has influence on the encapsulation of LED lamp pearl, refraction or reflection to light exert an adverse impact.
Utility model content
The purpose of this utility model is to provide a kind of heat dissipation type high LED circuit board technology scheme, by the technical program in the case of the reflection and refraction that do not affect light, the radiating efficiency of more effective raising LED lamp pearl.
A kind of heat dissipation type high LED circuit board, includes a circuit board main body, in a plane of described circuit board main body, is printed with two parallel metal electrodes, in the middle of two electrodes, is provided with at least one pit being separated, and pearl is positioned in pit LED lamp.In the circuit board main body of described pit inner bottom surface, be provided with a through hole; The external diameter of a circle of described through hole is less than the diameter of pit inscribed circle.
The degree of depth of pit is the half of circuit board main body thickness.
The utility model beneficial effect is compared with the existing technology:
By the through hole of the technical program, avoid the radiating effect because of the not good LED of the having influence on lamp of the heat conductivility pearl of circuit board.
Accompanying drawing explanation
Fig. 1 is the plan structure figure of the utility model circuit board;
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
Describe by the following examples the technical solution of the utility model in detail, should be understood that, it is the restriction to technical solutions of the utility model that following embodiment only can be used for explaining and the technical solution of the utility model being described and can not being interpreted as.
Shown in seeing figures.1.and.2, a kind of heat dissipation type high LED circuit board, include a circuit board main body 1, circuit board main body 1 is prior art, in a plane of described circuit board main body, be printed with two parallel metal electrodes (41,42), used in the present embodiment the better copper electrode of conduction and radiating effect, in other embodiment of the present utility model, can use as required aluminium electrode, brass electrode or aluminum alloy anode.
In the middle of two electrodes, be provided with at least one pit 2 being separated, the shape of pit 2 is not done requirement in the technical solution of the utility model, as long as it is just passable to match with LED lamp pearl 3 to be placed, LED lamp pearl 3 is positioned in pit 2.The degree of depth of pit 2 is the half of circuit board main body 1 thickness.In other embodiments, the degree of depth of pit can have different variations.In the circuit board main body of described pit inner bottom surface, be provided with a through hole 8.The external diameter of a circle of through hole is less than the diameter of pit inscribed circle.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
