The barbecue tube of light wave oven is changed from quartz tube or copper tube to halogen tube (i.e. light wave tube), which can quickly generate high temperature and high heat, with fast cooling speed, higher heating efficiency, no scorching and guarantee the color of food. In terms of cost, the cost of light wave tube is only a few dollars more than that of copper tube or quartz tube, so it is very common to use light wave tube in microwave oven technology now.

Essence: Light wave is an auxiliary function of microwave oven, which is only effective for barbecue. Without microwaves, a microwave oven is only equivalent to an ordinary oven. The optical wave furnaces in the market are all combined furnaces of light wave and microwave, which can be operated separately or in combination. In other words, the microwave oven is compatible with the functions of the microwave oven.
