The luminous angle of conventional lamp pearl side is roughly between 60 to 90, sets up the contained angle and can cooperate the light-emitting angle for 30 ~ 45, makes most light can both shine on the reflector layer.
According to a second aspect of the invention, a light source structure is provided, which comprises any one of the above-mentioned surface mount LED lamp bead support structures, a lamp bead and a fluorescent glue, wherein the lamp bead is fixed on the die bonding boss, the lamp bead is electrically connected with the positive electrode and the negative electrode, and the fluorescent glue is arranged in the inner cavity and wraps the lamp bead and the die bonding boss.
The invention has the advantages that the lamp beads are arranged on the die bonding boss, and light emitted from the bottom edge of the lamp beads is emitted to the reflecting layer on the inner wall of the inner cavity along the bevel edge of the die bonding boss, so that the light shielded in the old structural design is effectively reflected out of the surface mount LED lamp bead support structure through the reflecting layer, and the light efficiency is improved.
According to the light source structure of the second aspect of the invention, the area of the upper surface of the die bonding boss is 1/5-1/3 larger than that of the lamp bead. The glue that overflows is conveniently accepted to vacant position around the lamp pearl, prevents that glue from falling to the position that sets up the fluorescent glue, influences the light efficiency.
According to the light source structure of the second aspect of the invention, the height of the die bonding boss is 1-1.5 times of the thickness of the lamp bead.
