Technical field
The utility model relates to a kind of board structure of circuit of electricity-saving lamp, specifically refers to a kind of board structure of circuit of SMD lamp pearl LED electricity-saving lamp.
Background technology
LED(Light-emitting Diode, light-emitting diode), be a kind of solid-state semiconductor device, it can be electric energy conversion luminous energy directly.The heart of LED is a semi-conductive wafer, and an end of wafer is attached on the support, is negative pole, and the other end connects the positive pole of power supply, and whole wafer is got up by epoxy encapsulation.Semiconductor wafer is comprised of two parts, and a part is P type semiconductor, occupies an leading position in its hole, the inside, and the other end is N type semiconductor, mainly is electronics here.But when these two kinds of semiconductors couple together, just form one " P-N knot " between them.When electric current acted on this wafer by wire, electronics will be pushed to the P district, and then electronics will send energy with the form of photon with hole-recombination in the P district.It has the characteristics such as volume is little, power consumption is low, long service life, high brightness.
Nowadays, the SMD lamp pearl LED of strip type energy-saving lamp mostly adopts isosceles triangle to arrange or adopts two parallel rows to arrange mostly, although such structure has improved brightness, has improved cost, increase energy consumption, and do not given play to the characteristics of SMD lamp pearl LED high brightness fully.
The utility model content
Problem to be solved in the utility model provides a kind of board structure of circuit of paster LED electricity-saving lamp, the effect that reduce cost to reach, reduce energy consumption, brightness strengthens.
The technical scheme that the utility model provides is: the board structure of circuit of paster LED electricity-saving lamp; comprise pcb board; inside is provided with the circuit heart yearn; described pcb board divides tow sides; the front is installed surface; reverse side is radiating surface; described installed surface end is provided with the power supply pad; rectifier is electrically connected with the power supply pad; near studding with protective resistance in the power supply welding everywhere; it also comprises paster LED lamp pearl, and described paster LED lamp pearl each interval is arranged in a linear on pcb board, and paster LED lamp pearl is electrically connected with the circuit heart yearn by lead-in wire.
Described pcb board integral body is cuboid, highly is 1-2 centimetre.Be used for saving cost and space.
The heat radiation plastic material that described pcb board material adopts heat-conducting plastic Merlon and interior edge aluminium to be combined into.Nowadays the heat sink material of LED light fixture adopts aluminium matter mostly, but aluminium itself is on-insulated, produce easily safety problem, and the relative aluminium of the thermal conductivity of simple heat-conducting plastic is relatively poor and its rigidity is relatively poor, insufficient strength, so consider thermal diffusivity, intensity and the Insulation Problems of light fixture, adopt aluminium matter and heat-conducting plastic to form composite material, solved the heat dissipation problem of light fixture.
Described protective resistance is serially connected on the circuit heart yearn.Protective resistance for the protection of the SMD lamp pearl because of unlikely damages of situation such as outage, short circuits.
Be spaced apart the 3-5 millimeter between the described SMD lamp pearl.Adjust interval between the SMD lamp pearl according to required luminous intensity, thereby satisfy the demand of different light intensity degree.
Described SMD lamp pearl is adopted 2835 type SMD lamp pearls.Paster light fixture in the past mostly adopts 3528 or 3014 SMD lamp pearls, and 2835 types relative 3528 or 3014 SMD lamp pearl light-emitting areas are larger, lighting angle is large, radiating surface is large, and luminous evenly and 2835 be area source, and light transmission is better.
Described SMD lamp pearl is adopted the solder reflow welding.The process advantage of reflow soldering is that temperature is easy to control, can avoid oxidation in the welding process, and manufacturing cost is controlled easily.
The utility model has the advantage of: the board structure of circuit of this paster LED electricity-saving lamp of the utility model design has reduced cost, has reduced energy consumption, and brightness strengthens.
