Abstract

Including microwave sulfur lamp, the lampshade is made from photon crystalline material, which filters out green light from light beam from bulb totally, so that color-rendering index of microwave sulfur lamp is raised to 90 from 83. Selected photon crystal with special periodic structure allows specific light to be transferred. Thus, the lampshade can select transmission light beam so as to raise color-rendering index.

Description

technical field

[0001] The invention relates to a lampshade of a microwave sulfur lamp. Background technique

[0002] Existing microwave sulfur lamps use flat toughened glass lampshades, which do not selectively transmit the light emitted by the bulbs, so that the green light that reduces the color rendering of microwave sulfur lamps is also transmitted. The working principle of the microwave sulfur lamp system is as follows: the magnetron generates microwaves under the DC high voltage drive, and transmits them to the resonant cavity through the waveguide. . In order to make the plasma work uniformly and stably, the quartz bulb is driven by a motor to rotate at high speed. figure 1 It is the working principle diagram of the general primitive microwave sulfur lamp, figure 2 It is a schematic diagram of the lampshade and light transmission of the original microwave sulfur lamp. The lampshade 1 of the microwave sulfur lamp is made of tempered glass sheet. After the bulb emi...

Embodiment Construction

[0012] The lampshade of the microwave sulfur lamp of the present invention is described in conjunction with the accompanying drawings and embodiments.

[0013] Such as image 3 , 4 As shown, the lampshade of the microwave sulfur lamp of the present invention is an improvement on the material of the original microwave sulfur lamp lampshade. The original lampshade is flat tempered glass. of selective transmission. Such as image 3 The green part of the emitted light is reflected back to the lamp body by the lampshade 2, while the other parts are freely transmitted, and the color rendering index can be increased from 83 to 90 by using this improvement. The photonic crystal used is an artificial microstructure, which does not exist in nature. At present, there are two main methods for preparing photonic crystals: (1) precision machining method - precision machining method (2) colloid method - using dispersed colloid The self-organization characteristics of particle suspension ...
