pointí dearaidh cnapáin stiúir lasmuigh

      Due to the complex working environment of LED outdoor lighting lamps, affected by natural conditions such as temperature, ultraviolet, humidity, rain on rainy days, sand and dust, chemical gas and so on, over time, it will cause serious LED light failure. Therefore, in the end, outdoor lighting designers should consider the impact of these external environmental factors on LED outdoor lighting lamps.

1. Tá an bhlaosc agus an heatsink deartha ina n-iomláine chun fadhb teasa LED a réiteach. Tá an modh seo níos fearr. Go ginearálta, roghnaítear cóimhiotal alúmanaim nó alúmanaim, copar nó cóimhiotal copair agus cóimhiotail eile le seoltacht teasa maith. Áirítear le diomailt teasa diomailt teasa comhiompar aeir, diomailt teasa fuaraithe láidir gaoithe agus diomailt teasa píopa teasa. Tá tionchar díreach ag an rogha modh diomailt teasa ar chostas lampaí. Ba cheart é a mheas go cuimsitheach agus ba cheart an scéim is fearr a roghnú in éineacht leis na táirgí deartha.

2. Faoi láthair, tá an chuid is mó de na lampaí stiúir (lampaí sráide den chuid is mó) a tháirgtear le chéile le 1W faoi stiúir i sraith agus comhthreomhar. Tá friotaíocht teirmeach níos airde ag an modh seo ná táirgí a bhfuil ardteicneolaíocht pacáistithe acu, agus níl sé éasca lampaí ardchaighdeáin a tháirgeadh. Nó úsáidtear modúil 30W, 50W nó fiú níos mó le haghaidh cóimeála chun an chumhacht riachtanach a bhaint amach. Tá ábhair phacáistithe na stiúir seo cuimsithe le roisín eapocsa agus glóthach shilice. Is é an difríocht idir an dá ná go bhfuil droch-fhriotaíocht teochta ag pacáistiú roisín epocsa agus go bhfuil sé éasca le dul in aois ar feadh i bhfad. Tá friotaíocht maith teochta ag pacáistiú glóthach shilice, mar sin ba chóir aird a thabhairt ar roghnú nuair a bhíonn sé in úsáid.

    It is better to use multi chip and heatsink as a whole, or use aluminum substrate multi chip packaging, and then connect it with the heatsink through phase change material or heat dissipation silicone grease. The thermal resistance of the product is one to two less than that of the product assembled with LED devices, which is more conducive to heat dissipation. For lamps using LED module, the module substrate is generally copper substrate. Good phase change material or good thermal grease shall be used for its connection with the external heatsink to ensure that the heat on the copper substrate can be transmitted to the external radiator in time. If it is not handled well, it is easy to accumulate heat, resulting in too high temperature rise of module core and affecting the normal operation of LED chip.

3. Radiator is a key component of LED lamps. Its shape, volume and heat dissipation surface area should be designed to achieve benefits. If the heatsink is too small, the working temperature of LED lamps is too high, which will affect the luminous efficiency and service life. If the heatsink is too large, it will consume more materials, increase the product cost and weight, and reduce the competitiveness of products.
