Moltaí chun Teip Solas Sráide faoi stiúir a Réiteach
To solve these existing problems, it is recommended that street lamp manufacturers start from basic materials and solve the problem of high-power LED heat sources from the inside out. For example, thermal adhesive plays a key role in the bonding of light-emitting components and aluminum substrates. Some manufacturers think that the thermal conductivity of thermally conductive adhesive films or thermally conductive adhesive pads is better, and the thicker the film thickness, the better, but they do not think about thermal resistance. No matter how good the thermal conductivity is, the thermal resistance of the film thickness is useless. What's more, the thermally conductive adhesive film or soft thermally conductive gasket cannot really adhere to the substrate, and there are actually many pores on the bonding surface. These pores look like hollow air pockets under an electron microscope, another form of thermal resistance. In the presence of so many thermal resistances that interfere with heat conduction, the efficiency of heat dissipation and heat conduction is virtually reduced.
Bain úsáid as an ghreamachán seoltach teirmeach ceart, an greamachán seoltach teirmeach ceirmeach bog molta. Tá an ghreamachán seoltach teirmeach bog ceirmeach le haghaidh tógáil priontála scáileáin difriúil ón scannán greamaitheach seoltach teirmeach de chineál nasctha traidisiúnta. Tá an ghreamachán seoltach teirmeach ceirmeach bog bog agus leathleachtach. Nuair a chuirtear lann an mheaisín priontála scáileáin i bhfeidhm ar an tsubstráit alúmanaim, rachaidh na cáithníní seoltacha teirmeacha isteach sna pores ar dhromchla an tsubstráit. a líonadh go hiomlán. Ar an mbealach seo, déanfar eitleán go hiomlán cothrom gan phiocháin a fhoirmiú, a chloífidh go hiomlán leis an tsubstráit epitaxial LED. Ar an mbealach seo, laghdaítear an fhriotaíocht theirmeach go dtí an t-íosmhéid, agus is féidir an teas a dhéanamh go tapa, rud a laghdaíonn go nádúrtha teocht chomhthimpeallach an dísle stiúir, a shíneann saol an epitaxy agus a chuireann moill mhór ar tharla an lobhadh solais. Ina theannta sin, mar gheall ar insínteacht an phéint seoltaí teirmeach bog ceirmeach a chuireann priontáil scáileáin i bhfeidhm, le linn bácála ardteochta nó reflow, athróidh sé le leathnú teirmeach agus crapadh an tsubstráit alúmanaim. Is é an strus an-bheag, agus ní bheidh an tsubstráit alúmanaim a warped, gan trácht ar An pléascadh.
I gcosaint sheachtrach lampaí stiúir, moltar péint diomailt teasa bog ceirmeach a úsáid le haghaidh lampaí stiúir. Is féidir an spraeáil seo-cineál teasa bog ceirmeach-péint scaipthe teasa a spraeáil go díreach ar an taobh amuigh de lampaí LED, le tógáil agus oibriú éasca, agus is féidir é a oiriúnú do chruthanna éagsúla teasa-ag scaipeadh struchtúir, agus is féidir iad a choigeartú freisin go dathanna éagsúla chun freastal ar riachtanais dearadh tírdhreacha. Déantar nana-phróiseáil ar na cáithníní boga ceirmeacha sa spraeáil-phéinte a scaiptear. Ní hamháin go bhfuil na cáithníní fíneáil éasca leis an gunna spraeála a oibriú, ach freisin déanann siad na cáithníní seoltacha teirmeacha ar an limistéar brataithe céanna níos dlúithe agus níos dlúithe, ionas go mbeidh an limistéar ina bhfuil an teocht luaineach agus idirleata níos mó freisin. Lig do fhuinneamh teasa na lampaí stiúir a dhéanamh amach go tapa. Is ábhar teirmeasúthach í an phéinteáil bhog ceirmeach teasa, a chloíonn le caighdeáin cosanta comhshaoil agus sábháilteachta RoHS. Tá an nós imeachta tógála simplí agus ní gá aon trealamh speisialta. Tar éis bácála, tá sé teas-leasaithe agus is féidir leis teocht ard an LED a sheasamh ar feadh i bhfad gan aon athrú cáilíochtúil. Déanfaidh soilse sráide LED, soilse tírdhreacha, nó cláir fhógraí LED a úsáidtear lasmuigh freisin dochar d'aigéad agus d'alcaile ón ngaoth agus ón mbáisteach, mbualtrach éan báistí aigéadach, deannach aeir, astuithe deataigh dhubh, etc. ní mór go mbeadh tréithe friotaíocht aigéad agus alcaile ag péint diomailt teasa ceirmeach. Is é PH311 an raon friotaíochta aigéad agus alcaile atá ann faoi láthair, rud a d'fhéadfadh cuma lampaí lasmuigh faoi stiúir a chosaint go héifeachtach ó chreimeadh.
The cost structure of LED lamps and lanterns has been improved with the improvement of packaging technology, carrier board design, and heat dissipation module structure, and the quality has been continuously improved, and the cost has also decreased with the development of technology and market demand. However, there are not many manufacturers investing in material improvement, which is mainly related to the history and habits of Taiwan's industrial and commercial development. Taiwanese manufacturers are good at manufacturing process and design, and they pay less attention to the basic research and development of materials. Therefore, when it comes to solving technical problems or reducing costs, it is more inclined to purchase thinking or production management thinking. However, American and Japanese manufacturers will think from the perspective of applied materials, reduce costs, improve quality and increase profits from the perspective of innovation.
