詳細信息
2835貼片led燈珠主要適用于:球泡燈、面板燈、日光燈、噴畫燈、廣告燈等LED燈具。
1、芯片采用大功率背鍍鋁工藝,散熱更直接
2、芯片熱量直接從支架底部導出,相對3014散熱面積更大,散熱性能更加優良
3、發光面為長方形,相對3014、3528發光面積大、發光角度大,發光均勻,發光面積是3014的2.3倍,3528的2.1倍
4、2835為面光源,應用廣泛,克服3014側面發光角度小的缺點,有效解決3528照明應用中點光源現象
5、根據產品型號、客戶散熱使用條件,可采用20-150毫安多種電流使用
6、增加10%的透光率,可采用85-95%的透光罩,在LED日光燈上體現特別明顯。

Note:1.Luminous intensity is measured with a light sensor and filter combination that approximates the CIE (Commission International De L’Eclairage) eye-response curve.
2.1/2 is the off-axis angle at which the luminous intensity is half the axial luminous and intensity.
3.The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.
4.The IV guarantee should be added ±15%.
