A plurality of heat dissipation channels are annularly distributed between the outer side wall of the central lens and the inner side wall of the central channel, so that the heat dissipation effect is further improved.

The bottom of LED wafer mounting groove is equipped with the heat dissipation subchannel that extends to the lower extreme of central lens, and the heat of LED chip also can distribute away through the heat dissipation subchannel, and the radiating effect is better.

The housing, the center lens and the outer lens are coaxially arranged.

The shell is bowl-shaped.

The inner side wall of the bottom end of the shell is provided with a clamping groove, a buckle is arranged at the position, corresponding to the clamping groove, of the outer side wall of the outer lens, and the buckle is buckled with the clamping groove.

The upper end of the outer lens is provided with a positioning boss, and the positioning boss is matched with the top end of the shell in a positioning mode.

The central lens is thick at the upper end and thin at the lower end, and the central channel is thick at the upper end and thin at the lower end.

The shell is thin at the top end and thick at the bottom end, and the outer lens is thin at the upper end and thick at the lower end.

The utility model has the advantages as follows:

(one) the utility model discloses a through setting up heat dissipation channel on the combination formula lens to make lens itself have the circulation function of dispelling the heat, can be fine the gluey face temperature of LED chip dispel away, thereby solve the general illness of lens on the market now, in accurate accuse light, also can effectual reduction lens's temperature, reduce LED chip temperature, thereby increase the life of lamps and lanterns, because the gluey face temperature of LED chip is on the high side, can cause the lens to yellow, blacken, warp and so on.

(two) the utility model discloses an experiment and practice prove use this combination lens, compare with ordinary integrated lens on the market, under the equivalent condition, make the temperature of LED chip end at least 5 degrees, take the lens temperature under the equivalent condition and end 5 to 10 degrees.
