Shenzhen Hui Shi Lighting Technology Co., Ltd. is a professional engaged in LED product development, production and sales of high-tech enterprises, the products covered light class, commercial lighting, outdoor lighting and special lighting and other fields. Main business: LED dimming bulb, LED ceiling light, LED down light, LED panel lights, dimming series; LED track lights, LED Supermarket lights, LED high bay light, LED flood light and other indoor and outdoor products has been committed to the development, production and sales of LED lighting products. Currently, our products are widely used in all types of clothing stores, jewelry stores, shopping malls, supermarkets, hotels, factory lighting, home lighting environment villa, Hui Shi lighting products successfully applied to the following projects: Shenzhen Metro, Shenzhen Vanke Building, Shenzhen Xin Insein Business Building, Longgang Royal Court Hotel, Jeanswest clothing stores and more. COB Downlight is embedded in the ceiling of a beam of light down lighting, LED ceiling light, he is a fine classification, its light source is named COB package, high thermal conductivity aluminum and patent The new ceiling light honeycomb-type thermal structure design and production technology. Its most prominent feature is the ability to maintain the overall architectural unity and perfect, and does not undermine the perfect setting fixtures ceiling artistic unity; with the use of a light source hidden inside the building decoration, etc. on the structure. COB downlight in commercial lighting, home lighting use are broader, wider use wattage has 3w, 5w, 7w, 10w, 15w, 20w and so on. Suitable for use in a variety of different places, depending on user requirements brightness, exposure distance, width, and what needs to be exposed for installation at the scene and so on. Its product features are: 1.COB long life and low maintenance cost ceiling light: LED life of up to 50,000 hours, greatly reducing replacement and maintenance costs, LED ceiling light for the whole solid light, no tungsten wire, glass and other fragile parts, shock and vibration capability, easy to damage. COB light source module chip package directly bound to the heat sinking baseplate, less than the SMD process; small temperature difference between the chip and the substrate COB packaging, thermal performance and packaging costs better than imitation lumens High Power LED and SMD chip lamp beads more There are advantages. 2.COB Ceiling controllable: LED intelligent control technology, both single lamp control, another group control mode; different requirements depending on the scene, change control mode, giving colorful, cheerful rhythm feelings; according to LED controllable, colorful features, almost unlimited color composition, in accordance with the principles of the three primary colors plus digital gray control technology, evolved almost beyond the existence of any color on the principles of nature. 3.COB Ceiling safe: LED driver using low voltage isolation, generally use less than 36V safe voltage power supply, no risk of electric shock. LED is a cold light source, no heat radiation, the illuminated objects will not be heated. 4.COB Ceiling quiet comfort: no noise when working lamps, LED constant current driver, no rectifiers, no current sound. 5.COB Ceiling color is good: CRI LED light source is high, usually above 80, to restore the true qualities of objects, helps to reduce eye fatigue, protect eyesight great help.
