YUANNENGJI Delengen bahan cangkang lampu jalan surya LED. Die-cast aluminum is the best because aluminum has the best heat dissipation performance and is thicker. The aluminum shell is also OK and the price is more advantageous. Look carefully at the lamp beads to see if there is a lens. The light-emitting effect of the lens is better. Look carefully at the heat dissipation structure of the entire lamp head. Generally, the lamp beads are welded on the aluminum substrate, and thermal grease is used in the middle; secondary heat dissipation: the attachment surface of the aluminum substrate is an aluminum plate; the tertiary heat dissipation is an aluminum profile.
Look at the shell, lens, etc., to see its light frequency, and then see whether the light brightness of the lamp is bright; if it looks a little dirty, banjur iku banget kamungkinan sing kualitas lampu masalah. Yen lampu dalan solar, iku uga gumantung ing kualitas baterei; umume, baterei apik bisa terus kanggo sumber daya kanggo minggu sawise kebak. Of course, wektu iki ora tetep. Wektu sumber daya ing mangsa bisa uga luwih cendhek, sawise kabeh, wektu srengenge bisa uga ora suwe.
Deleng kromatisitas lampu kasebut. Generally, kromatisitas LED karo daya output dhuwur bakal luwih padhang tinimbang LED karo daya kurang, lan regane uga bakal luwih larang.
Deleng kemampuan anti-statis lampu kasebut: LED kanthi kemampuan anti-statis sing kuwat duwe umur dawa. Ngerti arus lampu: LED minangka badan pemancar cahya konduktif unilateral. Yen ana arus mbalikke, iku diarani bocor. LED karo bocor gedhe duwe siklus cendhak lan relatif murah.
Nalika tuku, pisanan katon ing cangkang lan lensa saka sirah lampu kanggo aran frekuensi padhang sawijining. Kapindho, nalika sirah lampu urip, priksa manawa intensitas cahyane padhang. Yen sirah lampu katon werna abu-abu lan krasa rada reged, tegese kualitas sirah lampu ora apik.
Iku uga gumantung ing kondisi baterei saka sirah lampu. Generally, baterei bisa ketemu sumber daya kanggo minggu. Yen wektu sumber daya cendhak, iku uga ateges sing kualitas sirah lamp ora apik, sing bakal nyuda umur layanan lampu jalan surya LED. biasa wae lampu jalan surya sirah ora kalebu baterei lan pengontrol. Rega saka kepala lampu jinis iki ditemtokake dening daya. Daya biasa antarane 10w-60w, lan rega kisaran saka 100 yuan kanggo 500 yuan. Harga head lamp solar kab, kang kalebu baterei lan panel photovoltaic, punika ewu yuan. Kanggo mangerteni bagean, ana akeh jinis tartamtu saka bagean, utamane panel surya, sel surya, panel surya, sumber cahya, etc., dadi nalika milih panel surya, sampeyan uga kudu nimbang materi, werna cast, saiki, voltase sirkuit mbukak, efek konversi lan faktor liyane saka panel cahya. Of course, nalika nggawe pilihan apik, sampeyan uga kudu ngerti kahanan cocog rinci.
Akeh manufaktur’ produk ora dadi dipercaya nalika digunakake minangka peralatan cahya. Alesan utama yaiku ana masalah sing cocog ing cocog. Fungsi sing cocog minangka salah sawijining tujuan sing paling penting, supaya iku penting banget kanggo ngerti fungsi cocog cocog.
