Furthermore, internal thread fixing pipes are welded at two ends of the top of the support.

Furthermore, No. two mounting holes are opened at the PCBA both ends.

Furthermore, a first mounting hole is formed in each of two ends of the condenser, and the condenser is made of a metal copper material.

Furthermore, a plurality of positioning clamping grooves are formed in the inner side of the condenser.

Compared with the prior art, the invention has the following beneficial effects:

1. through setting up PCBA, optics speculum face and internal thread fixing pipe, the fixed outside of tubes of internal thread including the personnel will No. two mounting hole covers, make PCBA install on the support, the LED wick is installed through the mount pad in the PCBA top, the personnel with the fixed outside of tubes of internal thread including the mounting hole cover, install the spotlight ware at the PCBA top, the cover is in the LED wick outside after the spotlight ware installation, the light that sends in the face of LED wick through a plurality of optics speculums of inboard retrains, the reflection, personnel use the bolt to fix spotlight ware and PCBA through the fixed pipe of internal thread.

2. Through setting up leaded light post, positioning groove and spotlight ware, insert the leaded light post in the spotlight ware and fixed, a plurality of positioning groove in the spotlight ware can be fixed the leaded light post, can solve the problem that position and design position between LED and the light guide have certain deviation in the actual installation simultaneously to improve optics utilization ratio, the spotlight ware is made by metal copper material, and thermal conductivity is good, can effectively dispel the heat.
