Abstract
The utility model relates to a high-power high-radiation LED bead comprising LEDs, a circuit board, a radiating plate, shells, adhesive, and wires. The LEDs are fixed on the circuit board and connected with two electrodes of the circuit board through the wires. The shells fixedly connected with the circuit board are arranged above the LEDs and filled with the adhesive. The radiating plate is fixed to the surface, facing the LEDs, of the circuit board. The adhesive between the LEDs and the radiating plate and pits in the circuit board help effectively improve radiating effect, the lives of the LEDs are prolonged, and light attenuation rate is decreased.
Description
Technical field
The utility model belongs to electrical lighting field, refers to Light-Emitting Diode LED, refers to that especially one has high-power high-heat-dispersion LED lamp 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.
Utility model content
The purpose of this utility model is to provide the technical scheme of a kind of high-power high-heat-dispersion LED lamp pearl, by the technical program, effectively improves radiating efficiency in the situation that not improving radiator cost.
The utility model is achieved through the following technical solutions:
A kind of high-power high-heat-dispersion LED lamp pearl, is made up of LED lamp pearl, circuit board, fin, shell, colloid and wire; Described LED lamp pearl is fixed on circuit board and with wire with two electrodes connections on circuit board; LED lamp pearl top is provided with the shell that same circuit board is fixedly connected with, and envelope filled have a colloid; Described circuit board is fixed with fin with the relative surface of LED lamp pearl.
Between two electrodes of described circuit board, be provided with the pit that same LED lamp pearl adapts, the center of pit is provided with through hole, is provided with the heat conduction colloid layer that same LED lamp pearl is connected with fin in through hole.
The circumradius of described through hole is less than the inradius of LED lamp pearl.
Described shell is transparent outer cover, and described colloid is transparent heat conduction colloid.
The utility model beneficial effect is compared with the existing technology:
Setting by pit on the colloid setting between LED lamp pearl and fin and circuit board effectively raises radiating effect, and the life-span of having improved LED has effectively reduced the speed of light decay.
Accompanying drawing explanation
Fig. 1 is the utility model board structure of circuit schematic diagram;
Fig. 2 is the A-A sectional view of the utility model 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 high-power high-heat-dispersion LED lamp pearl, by the power of LED lamp pearl in the present embodiment for 1W at least, circuit board 1 for printing copper coin circuit board, fin 6 for Aluminium Radiator, shell 2 be that to be transparent heat conduction colloid and wire 5 form for gold thread for transparent plastic shell, colloid.
Two electrodes (41 of circuit board 1,42) between, be provided with the pit 7 that same LED lamp pearl 3 adapts, the degree of depth of pit 7 is the half of circuit board thickness, LED lamp pearl 3 sticks at the bottom of pit 7 by heat-conducting glue, gold thread is welded on two electrodes of circuit board 1, the center of pit is provided with through hole 8, and the circumradius of through hole is less than the inradius of LED lamp pearl.In through hole, be provided with the heat conduction colloid layer that same LED lamp pearl is connected with fin, the laminated connection of heat conduction colloid LED lamp pearl another side connects radiator.
LED lamp pearl top is provided with the transparent plastic shell that same circuit board is fixedly connected with, and in shell 2, is filled with colloid; Described circuit board is fixed with fin with the relative surface of LED lamp pearl.
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.
