arahina Poari PCB kua whanakehia te hangarau ki roto i nga mahi hou hou. He tauira pai ko te whanaketanga o PCBS mo nga rama a LED. The LED is welded to the circuit board, and the chip produces light during the electrical connection. Ka whakamahia te takotoranga wera me te papa uku hei hono i te maramara kia mimiti te wera kia whakamatao i te kaupapa.

Ko nga panui LED PCB ka kaha ki te whakaputa i te wera, na te kaha o te whakapau i te tikanga o te mahi. Na, ko te tikanga kowhiri i te poari ara iahiko Core LED hei whakapai ake i te kaha o te wera o te LED. Ina koa, he whakamahia te konumohe hei hanga papa iahiko mo nga rama rama. Aluminum PCBS typically include a thin layer of thermally conductive dielectric material that relocates and dissolves heat, providing excellent coherence compared to unyielding PCBS.

Tono PCB LED

Ka taea te whakauru i nga taapiri PCB LED ki nga waahanga rama maha na te kaha o te kaha, te iti o te utu me te waatea hoahoa tino nui, penei i te:

He maama te huarahi

Nga Taatai ​​pereoo

Rama rama

Street tunnel lighting

Te papa rererangi rererangi

Street lamp lighting

Whakaahua Photovoltaic (solar)

He maarama rama me te rama

Rama i roto i te ruuma whakahaere i te hohipera

Rama rama me era atu

E whakarato ana a RayMing i nga whakautu rama rama whaihua me te utu

Hei otinga mo nga papa ara iahiko LED neke atu i te tekau tau te roa o te wheako, ka taea e taatau te whakarato i nga papaa hiko a LED, te whakahiato me te whakahiato i nga waahanga i raro i te tuanui kotahi. Kei te hari matou ki te mahi tahi me koe ki te whakawhanake i nga papa konumohe / whakarewa ritenga mo to tono motuhake. Ka whakaekea e maatau nga papa FR-4 paerewa paanui me nga miihini konumohe-konumoana e kaha ana te whakakore i te wera, te whakamatao i nga waahanga hiko a LED me te whakapai ake i te mahinga hua.

He aha te mea whakauru PCB LED me te pehea e mahi ai?

Ko nga Reds e tu ana mo nga rama-emitting (rama). He diode semiconductor a no te roopu rama hiko hiko, e whakaputa ana i te rama ma te whakakotahi i nga takirua kaikawe utu i roto i nga semiconductors me te āputa roopu e tika ana. Due to their low voltage, operating power, compact size, long life and stability, leds are used in both industrial and consumer markets. Ko tetahi o nga mea tino ataahua ko tona kaha ki te whakaputa i te maama me te kore e whakaputa i te wera, kia pai ai te whakamahi o ia ra. Its functionality is the main reason leds are integrated into printed circuit boards (PCBS). He pono, he whaihua hoki nga raiti mo nga tono PCB. He maama ta ratou mahi, ina koa i roto i nga huringa kiriata pa-kore. Ko nga papa LED whakauru e whakamahia ana mo nga whakairoiro polyester me nga papapihi rapa.

Ko te atanga kaiwhakamahi

Circuit boards are usually used for the lower circuitry of membrane switches, especially since they provide it. Display LED display window. These are usually easy to integrate into printed circuit board switch designs, but there are some choices about which type of LED to use.

Single point and block LEDS

They do the most and work the best of almost any type of surface material. Kia mahara ko nga papa kakano me nga papa kakano ranei ka pai ake te whakamahi mo te horahanga maramara nui atu. It is also important to remember that although leds cannot touch the active area of the switch, they can be made to believe they are part of the switch by graphical manipulation.

Tuuturu mata-eke mata ira kotahi ranei

Ka whakauruhia, kia whai waahi ranei te LEDS kotahi ki te mowhiti o raro. Mo enei momo reiti, ka taea te whakamahi i nga tae rereke, tae atu ki nga reera tae-rua. Ka hangaia ana te paparanga whakairoiro hei tango i te LED, he maama ki te whakamutu i te whakamutu mai i te pito kotahi o te hononga. Kia mahara kaore koe e hiahia ki te pupuri i te mahere whakaotinga a LED i roto i te rarangi motuhake.

Nga painga o te PCB LED tuitui

I te mea ka angiangi nga waahanga hiko, he pai te whakamahi i nga huringa kiriata LED na te mea ka ngawari te tuku hua me te huihuinga whakamutunga. Ko enei kaata LED tuuturu he pai ake mo te whakamarama iti, te kaihoko, nga taputapu, nga taputapu hauora, te maama me te umanga me etahi waahanga moana me nga waahanga a-taiao. Ahakoa te tono, ko nga painga o nga papa LED tuuturu he maha:

Maama me te kore e aro

He utu iti mo te huri kiriata

Aukati i te puehu me te makuku

He ngawari ki te whakauru ki nga taakaro matatini

He iti te kohi kaha

E waatea ana i nga momo tae, rahi me nga pakaritanga

Ka taea te whakamahi mo te huringa kiriata hiriwa ngawari me te huri i te kiriata parahi parahi

Mena kua whakauruhia nga reimana ki roto i te papa ara iahiko, ka maama ake te whakakotahi i nga whakakapi kiriata angiangi a LED me nga papapātuhi, nga mata pa me etahi atu momo huri kiriata angiangi. Ko te PCBS LED kua whakauruhia, kua whakauruhia ranei, he nui ake te herekore o te hoahoa ahakoa kei te hanga i nga waahanga pana whakamuri uaua. Ko te matotoru iti o te whakakii kiriata angiangi LED ka whakaiti i te waahanga katoa o enei waahanga whakawhiti matatini. Designers and engineers often choose integrated LED PCBS when inspecting and updating products.

I te nuinga o te waa, ko te PCBS LED e whakarato ana i te rama whakamuri tino pai ki nga kaiwhakamahi mo te whakawhiti kiriata angiangi. I etahi wa ka pai ake te kowhiringa mo te whakamarama i nga ICONS iti me nga tohu na te mea kaore i te ngawari te whakatutuki i te whakamarama o te ICONS nui me nga tohu me nga huringa LED PCB whakauru.
