2835贴片led灯珠主要适用于:球泡灯、面板灯、日光灯、喷画灯、广告灯等LED灯具。
1、芯片采用大功率背镀铝工艺,散热更直接
2、芯片热量直接从支架底部导出,相对3014散热面积更大,散热性能更加优良
3、发光面为长方形,相对3014、3528发光面积大、发光角度大,发光均匀,发光面积是3014的2.3倍,3528的2.1倍
4、2835为面光源,应用广泛,克服3014侧面发光角度小的缺点,有效解决3528照明应用中点光源现象
5、根据产品型号、客户散热使用条件,可采用20-150毫安多种电流使用
6、增加10%的透光率,可采用85-95%的透光罩,在LED日光灯上体现特别明显。

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%.
