On total both positive and negative polarity pad 23.Right the design not limited to this, in other embodiment, light source substrate 21 can also be metal substrate,
Such as, but not limited to aluminium base or copper base etc., and the front of light source substrate 21 is provided with thermally conductive insulating layer, the thermally conductive insulating layer
Thickness be more than 0.1mm.In addition, in the present embodiment, the requirement of safe voltage, i.e. surface electricity should be met in terms of circuit design
Road connection line is protected by high insulating materials, and combine the surface of light source substrate 21 formed efficient circuit, when using eutectic without
After gold thread encapsulation technology compound chip, circuit is to form complete closed circuit, and this setting can effectively reduce LED chip 22 itself
Internal stress and hole problem after heating and embedding.
Referring to figs. 1 to Fig. 5, in the present embodiment, in the assembled condition, the close-fitting of light source substrate 21 is placed in mounting groove 11
In, and it is Nian Jie with the sealing of installing plate 1, in this way, when can prevent from injecting explosion-proof glue 3 into embedding hole 12, occurring glue side
Leak phenomenon.Specifically, the thickness of installing plate 1 is preferably 6~7mm, and mounting groove 11 and embedding hole 12 are square, wherein, install
The depth of groove 11 is 0.9mm.
Further, in the technical solution of the utility model, when being welded with positive and negative polarity wire 24 on pad 23, pad
Tie point between 23 and positive and negative polarity wire 24 is solder joint, the solder joint be in whole light source substrate 21 with the inner side of installing plate 1 away from
From nearest powered point.Minimum range between the solder joint and the inward flange in embedding hole 12 is D, meanwhile, in explosion-proof glue 3
During containing fluorescent material, the distance between powered point higher in solder joint and LED chip and the glue surface of explosion-proof glue 3 are defined as H；
