The RGB LED floodlights product components. Lens + LED integrated light source (COB) + LED power supply + die-cast aluminum housing = RGB LED floodlights 1, Lens. Process: There are two kinds, one is physical tempering and the other is chemical tempering. Physical tempering is the production of ordinary flat glass or float glass by quenching or air-cooling fire treatment under specified conditions and environments. Chemical tempering is a process in which ordinary flat glass or float glass is subjected to ion exchange to change the composition of the surface of the glass to form a laminated stress layer on the surface of the glass. Good and bad discrimination: check for quality defects such as flatness, no air bubbles, inclusions, scratches, lines and fog spots. Glass with such defects will be deformed during use, reducing the transparency and mechanical strength of the glass. The thermal stability of the glass. 2, flood cover Discrimination method: no deformation, no spin lines, n...

Color temperature is a physical quantity used in illumination optics to define the color of a light source. That is, when a black body is heated to a temperature, and the color of the light emitted is the same as the color of the light emitted by a certain light source, the temperature at which the black body is heated is referred to as the color temperature of the light source, referred to as the color temperature. The unit is expressed in "K" (Kelvin temperature unit). The color temperature of the source is determined by comparing its color to the theoretical thermal blackbody radiator. The Kelvin temperature of a hot black body radiator matching the color of the light source is the color temperature of that source, which is directly related to the Planck blackbody radiation law. The color temperature is defined by the absolute black body. When the radiation of the absolute black body and the radiation of the light source are exactly the same in the visible region, the temperature...

There are many places where you can buy RGB LED flood lights. You can buy it at your local mall or check out the RGB LED flood lights at some online stores. However, they will not give you the best price. To get the best quote for the RGB LED flood lights batch requirements, you must contact the LED manufacturer and supplier directly. China is the largest market for LED lights, with thousands of suppliers working in the floodlight business. But the challenge is to find the best one. Last year, I started looking for similar supplier information and talked to more than 20 LED manufacturers and suppliers after checking their online business. I decided to work with Ruichuan. This is what our customers say. Zhongshan Ruichuan Lighting Co,. Ltd. is a led lighting manufacturer from China which was established on January 25th, 2005 . At present, we have two factories. Shenzhen headquarter, covering an area of 5000 square meters, mainly produces LED components and amusement LED lights. Zhon...

Ordinary incandescent lighting effects are about 10 lumens per watt, and the life expectancy is about 1000 hours. Its working principle is: when the light is connected into the circuit, the current flows through the filament, and the thermal effect of the current causes the incandescent lamp to emit continuous visible light and Infrared, this phenomenon can be noticed when the filament temperature rises to 700K. Because the filament temperature during operation is very high, most of the energy is wasted in the form of infrared radiation. Because the filament temperature is high, the evaporation is also fast, so the life is also Large shortening, about 1000 hours; in terms of energy saving, traditional incandescent lamps due to a large amount of infrared energy loss and high temperature heating, short life, the introduction of advanced energy-saving green lights is an inevitable power-saving revolution . LED lamp is a kind of semiconductor lamp capable of converting electric energy ...
