Description of the invention (3) Far-infrared wavelength light flow; and the stripping method of the heat temperature generated by the bulb, due to the existence of a natural convection between cold air and hot air, by virtue of its cold and heat The principle of the unequal mass of the gas molecules and the unequal mass of the gas causes the hot and cold air to form a natural AC state. In the present invention, the grating assembly 2 can be used to effectively pass hot and cold air and cool the light bulb. The light blocking plates 2 and 2 3 of different sizes are used to make the smaller light blocking plate 2 under the effect of the interval. 3 The outer round edge maintains a certain distance from the inner surface of the housing, and a larger light blocking plate 2 2 is formed between the inner round edge and the outer round surface of the sleeve 4 to form a certain spatial distance, and a certain distance is generated by each distance space. The through-flow exchange of hot and cold `` S 〃-shaped channel 5, by which the channel 5 can effectively supply hot and cold air to enter, exit and exchange the heat generated by the bulb 10, and-J2L, and because the far infrared is caused by the The visible light projected by the light bulb is converted into invisible light. Therefore, the visible light flow of the light bulb must be effectively prevented, and the light flow cannot be transmitted out. Therefore, by using the multi-stage grating assembly of the present invention, the heat can be provided first. Cold air is brought in from the passage 5 and the bulb 10 is cooled and then passed through the opposite running line to achieve the cold and heat convection effect. Besides, the light blocking plates 2 2, 2 3 and other light blocking plates Staggered interval method, which can effectively block Linear visible light; In addition, the light flow scattered by the light bulb 10 cannot be directly scattered inside the housing through the light blocking effect of each group of light plates, and because of the existence of the multilayer light blocking plate, the light The flow in the inside of the casing 10 has the effect of being directly blocked, or the reflection is increased, and the inside of the casing and each light can be blocked.

五、發明說明（4) 板等元件外表，塗上易於吸光之表面色澤，如平光霧面之黑色塗料，或以電鍵等方式，可使該表面形成可吸光者，因此使殼體所投射出之光流單純為遠紅外線光，且本發明在實驗上，該防止可見光穿流散射出之測試效果非常良好。又在空氣交流的冷卻實施上，由於該遠紅外線轉換渡鏡2 5係靠近於燈泡1 〇，使該轉換瀘鏡2 5與燈泡1 〇對面之間保持在較短小的空間，相對因為該空間較為狹小’因此燈泡1 〇所產生的熱度，可在該小空間内，快迷的加熱使所囤積的空氣，在極短時間内，易於反應，使對該區的冷空氣能高速加熱’藉該冷空氣澎漲之後，密度變低’而可從上部的通道5所形成的運行線直接排放出，又藉其排放速率的作用，而產生一個冷熱帶換的效果，當然該轉換渡鏡2 5的座落位置，只要在殼體内部的任何位置’都可達到轉換效果，不同的是，藉由該轉換瀘鏡2 5 ’係為一板狀的板狀體，因此可對空氣作内外的阻隔，相對於燈泡1 〇之一面’由於與燈泡保持較近距離，可縮小其燈泡熱溫作用反應空間’而提升該加熱反應速力，藉由該速率的提升，相對也提升該冷熱空氣對流的流速，增加其熱溫的帶換速率’而達到有效的對燈泡本體作有效的散熱。今又遠投光器應用於室外的時候，由於必需接受風雨的侵襲’而藉由該多階式光栅組件裡部所設的多層阻光板2 2、23，及該套管4内端與轉換瀘鏡25為密接式，可V. Description of the invention (4) The surface of components such as boards is coated with surface color that is easy to absorb light, such as black paint with flat matte surface, or by means of electric keys, etc., which can make the surface absorbable. The light flow is simply far-infrared light, and in the experiment of the present invention, the test effect of preventing visible light from passing through and scattering is very good. In the implementation of air-cooling, the far-infrared conversion mirror 25 is close to the light bulb 10, so that the space between the conversion mirror 25 and the light bulb 105 is kept in a relatively short space. It is relatively narrow 'so the heat generated by the light bulb 10 can be stored in this small space, so that the accumulated air can be easily reacted in a very short time, so that the cold air in the area can be heated at high speed' After the cold air surges, the density becomes low, and it can be directly discharged from the running line formed by the upper channel 5, and by the effect of its discharge rate, it produces a cold zone change effect. The seated position of 5 can achieve the conversion effect as long as it is in any position inside the shell. The difference is that the conversion mirror 2 5 'is a plate-shaped plate-shaped body, so it can be used for air inside and outside. Compared with the one side of the light bulb, the heating reaction speed is increased due to the distance between the light bulb and the light bulb, which can reduce the reaction space of the heat and temperature of the light bulb. The velocity of the hot air convection increases its heat transfer rate to achieve effective heat dissipation from the bulb body. When the long-range light projector is applied outdoors, it must be exposed to wind and rain. Therefore, the multilayer light blocking plate 2 2, 23 provided inside the multi-stage grating assembly, and the inner end of the sleeve 4 and the conversion mirror 25 is close contact type, but

Another object of the present invention is to provide the grating assembly as a single device assembly via the connecting member 2 1 or the sleeve 4, and provide an integrally removable casing that can be directly removed by hand for necessary maintenance. After the light bulb is 0 'or removed, clean the mirror of the conversion board. In addition, the single-unit grating assembly 2 can be attached to the outside of the housing by a support member after being pulled out. The support member is designed in various ways, such as linking or telescopic rods, and is temporarily fixed to the unit. The effect of the exterior of the casing or the suspension effect is provided when the light projector is disassembled and maintained, and the light barrier assembly can be taken out with one hand to release the support of the limbs. The one-handed operation is convenient for high-altitude operations. After removing or maintaining the bulb, or even withdrawing it, you can easily clean the mirror lens and clean the mirror surface. Another object of the present invention is to remove the far-infrared conversion mirror and replace the mirror. The transparent glass partition can be used for the projection of general visible light flow.
