Embodiment Construction
[0041] Please also see figure 1 and figure 2 ,in, figure 1It is a cross-sectional structural schematic diagram of an LED device with a transition substrate in the present invention, figure 2 yes figure 1 The shown schematic diagram of the cross-sectional structure of the LED unit arranged on the metal substrate.
[0042] Such as figure 1 As shown, the LED COB device with a transition substrate of the present invention includes: at least one LED unit 1 , a metal substrate 2 , a dam 3 and an encapsulant (not shown in the figure). The LED unit 1 is welded on the metal substrate 2 and electrically connected thereto. The dam 3 is arranged on the edge of the metal substrate 2 and surrounds all the LED units 1 on the metal substrate to form an enclosing area 4 for packaging. The encapsulant is filled in the surrounding area 4 and covers and seals all the LED units 1 inside.
[0043] Specifically, such as figure 2 As shown, the LED unit 1 includes an LED chip 11 and a trans...
