你知道,防水网络摄像机是如何散热的?

来源:http://www.hainanztb.com  发布时间:2018-08-16
咱们都知道,当摄像机用的时间比较长的适合,会出现一层薄雾,到底是什么原因引起的呢?不必担心,今天就为咱们讲解防水网络摄像机是怎么散热的。
As we all know, when the camera is suitable for a long time, there will be a layer of mist. What is the cause? Don't worry. Today we will explain how the waterproof webcam is dissipating.

防水网络摄像机是用的58的灯串连做成灯板,它的灯所发生的热是经过正负级来传送出来,而且起不到一个散热的作用,它的封装资料是选用环氧树脂,作业一段时间会出现开裂层,然后呈现光衰这种现象,3个月后传统红外防水网络摄像机能够衰减30。下面就为济南保安服务公司讲解下防水网络摄像机是怎么散热的。
Waterproof network camera is made of 58 lamps in series. The heat generated by its lamp is transmitted through positive and negative stages, and it can not play a role in heat dissipation. Its packaging material is epoxy resin. Cracking layer will appear during operation, and then the phenomenon of light fading will appear. Three months later, the traditional infrared protection. Water network cameras can attenuate 30. Here is the Ji'nan security service company to explain how the waterproof webcam is dissipating.
雾、霜的构成是由于空气中的饱满水蒸气遇冷凝聚而成,因冷环境的强、弱分别凝聚成霜和雾。红外摄像机在作业过程中,尤其是在室内的摄像机常常会因雾气或许水汽等原因在防护罩视窗玻璃上构成雾或霜,导致摄像机无法看清物体,直接影响监控作用。
The composition of fog and frost is due to the condensation of full water vapor in the air when it is condensed, and the frost and fog are formed respectively because of the strong and weak cold environment. Infrared cameras, especially indoor cameras, often cause fog or frost on the windowpanes of protective covers due to fog or water vapor, which makes the cameras unable to see objects clearly and directly affects the monitoring effect.
各家对这一问题的处理方法也是不一样的。添加除霜电路、注册气孔、充氮气、加风扇、放干燥剂等等。方法不一样,做出来的作用当然也不一样,有的能够处理问题,有的仍是不能处理问题。不过,从最根底的视点上来讲,严格控制料件的清洗,尽量根绝挥发物的存在是很有必要的。例如PCB板不能有残留助焊剂,遮光胶套采用优质硅胶资料等。
There are different ways of dealing with this problem. Add defrosting circuit, register air hole, fill nitrogen, add fan, put desiccant and so on. Different methods, of course, have different effects, some can deal with problems, some still can not deal with problems. However, from the most fundamental point of view, it is necessary to strictly control the cleaning of the material and try to eradicate the existence of volatiles. For example, PCB plates should not have residual flux, and the light shield should be made of high quality silicone materials.
为了改动这个因散热不好而导致红外防水网络摄像机寿数不长的情况,新一代的红外防水摄像机在灯方面做了创新和改进。
The new generation of infrared waterproofing cameras have made innovations and improvements in the field of lighting in order to change the situation that the lifetime of infrared waterproofing network cameras is not long due to poor heat dissipation.
新一代的红外防水摄像机是用的单颗灯,它的一颗灯相当于传统摄像机红外灯的70—80颗,它的灯是经过灯板(灯板用的是铝合金)衔接灯的还有一个散热块,经过芯片衔接外壳,然后得到散热作用,它的封装资料是选用硒胶,由于没有开裂层,也不会出现光衰这种现象,夜视作用非常好,寿数能够到达5—10年,2年内肉眼看不到任何衰减。

The new generation of infrared waterproof cameras uses a single lamp, one of which is equivalent to 70-80 of the traditional cameras'infrared lamps. The lamp passes through the lamp board (aluminum alloy used for the lamp board) connecting lamp and a heat sink, which passes through the chip connecting shell and then gets the heat dissipation effect. Its packaging material is selenium glue. Because there is no cracking layer, there will be no such phenomenon as light decay, night vision is very good, life can reach 5-10 years, within 2 years the naked eye can not see any attenuation.
所以新一代的红外防水网络摄像机的散热很好,假如用了后发现外壳摸上去很热,说明它的热能散出来了。散热好也就延长了寿数。
So the new generation of infrared waterproof network camera heat dissipation is very good, if used after the shell feels very hot, indicating that its heat dissipation. The good heat dissipation also lengthened the number of lives.
新一代红外防水网络摄像机它是许多个点集成的,每颗点阵灯可集成60-80粒LED发光晶体,集成后的体积也只要指甲盖巨细,制造制品体积也不会太过巨大。由于点阵灯为高度集成的LED,故体积比其他产品小许多。
The new generation of infrared waterproof network camera is a multi-point integration, each lattice lamp can be integrated 60-80 LED light-emitting crystals, the integrated volume of the nail cover as long as the size of the manufactured products will not be too large. Because dot matrix lamps are highly integrated LED, they are much smaller than others.
体积小最主要是便于应用,假如用几十个单个LED组合的红外光源装置时高速球机上,作用是可想而知的。一般产品的发光视点一般为7°-10°角,故构成一道有如手电筒般的光束,咱们的发光体的视点最大可到180°。在室内可均匀照亮全部空间。单个LED的光学输出为5mw-15mw,而一个点阵灯的光学输出到达了800mw-1000mw,而体积有只要一个一分钱硬币的巨细。这表明点阵灯比市面上同类产品更明晰、更亮堂、更远间隔的监控画面。
Small volume is the most convenient for application, if the use of dozens of single LED combination of infrared light source device on the high-speed ball machine, the role is conceivable. Generally, the luminous viewpoint of a product is 7-10 degrees, so it forms a torch-like beam. The maximum viewpoint of our luminous body can reach 180 degrees. It can illuminate all spaces in the room. The optical output of a single LED is 5 mw-15 mw, and the optical output of a dot array lamp is 800 mw-1000 mw, which is about the size of a penny. This indicates that dot matrix lamps are clearer, brighter and more remote monitoring screens than similar products on the market.
还有两种可能就是:一、可能是由于有水气掩盖在镜片上,发生的含糊!另一方面,是产品选用的Sensor不是很好,用久后老化了,画质就显得含糊了,还有可能是产品密封性不是很好,有水气掩盖在镜片上。二、机器自身的工艺问题,网络摄像机质量不过关的话就会简单呈现镜头钱起雾,橡胶垫圈出油,图画发白,雪花点多,噪点大等现象,这是由于密封的皮圈老化构成的。
There are two possible reasons: first, it may be due to the ambiguity of water vapor on the lens. On the other hand, the product is not very good, after a long time aging, the quality of the picture becomes vague, and there may be product sealing is not very good, there is moisture masked in the lens. Second, the technical problems of the machine itself, if the quality of the network camera fails to pass, it will simply show the lens money fogging, rubber washer oil, picture whitening, more snowflakes, noise and other phenomena, which is due to the aging of the sealed leather ring.
