Floodlights supplier in China: DALI Dimming – It is a communication interface called a digital addressable lighting interface (DALI). It allows brightness control, color temperature control, recall preprogrammed settings, group control, and error diagnosis capabilities. It transmits data using the existing power lines to control a set of lights. Pulse-Width Modulation (PWM) – It is a method of turning the LED on and off faster than the frequency cycle. The rapid cycling decreases brightness and pulse width. It is a more common technique in small street LEDs. NAMA Connector – Photocells can connect to the light using a NAMA connector with 3-pin, 5-pin, and 7-pin configurations. A photocell connection with the 3-pin NAMA connector will turn the light ON/OFF based on ambient light. A 7-pin connector provides the flexibility of brightness control with lighting conditions.

The technology of HID lamps can be traced back to 1675, when Jean-Felix Picard discovered that his mercury barometer glows when shaken. However, the first HID commercially available bulb was made in 1965. It produces 95 lumens/watt, which is competitive with HPS and LED but also has similar omnidirectional light problems. The electricity that goes into the bulb passes through the xenon gas inside the glass chamber. It causes the xenon gas to ionize, forming an arc that vaporizes sodium and mercury to create light. The light is yellow in the range of 1900 to 2000 degrees Kelvin. These lamps have low color rendering capabilities. HID lamps also pass high electricity through a gas to create light. They require a ballast to operate. They contain tungsten electrodes inside a fused alumina arc or quartz tube. The noble gas of suitable metal or metal salt is used to enable the arc’s initial strike. They are also known as arc lamps.
The initial cost of an LED-type floodlight is higher, but it pays off early due to its> 90% electrical efficiency. Halogen lights offer more brightness than LED lights, but if we think of brightness in terms of lumens per watt of electricity consumed, LED flood lights are the clear winner. They come with metal heat sinks, which dissipate the very little heat generated during operation. It makes LED lights cooler to the human touch. Users prefer placing them in parking lots, sports fields, security fences, etc. Metal Halide – These are High-Intensity Discharge (HID) lamps. They consist of a mixture of mercury in gaseous form and metal halides (metal compounds formed with iodine or bromine). When an electric current is passed across the arc tube, gas is ionized, and as the temperature increases, the metal halides dissociate into metal atoms and halogen atoms.
The LED tube uses a light-emitting diode as a light source, which has higher luminous efficiency, is more energy-saving, has a longer service life, and is more environmentally friendly. It is the ideal product to replace fluorescent tubes at this stage. The LED tube and the traditional fluorescent lamp are the same in the outer size. There are T5 tube, T8 tube and T10 tube. The length is 0.6m, 0.9m, 1.2m, 1.5m, 1.8m, 2.4m. The installation of the LED tube is very simple. When installing, the original fluorescent lamp is removed and replaced with the LED tube, and the ballast and the starter are removed, so that the 220V AC mains can be directly applied to the ends of the LED tube.

Waterproof problems in the installation of LED street lights: After ensuring the quality of the lamp holder, you need to pay attention to the technical problems of the lamp holder installation and construction. Most of the led street light controllers are installed in the lampshade and battery box, and generally will not enter water, but in actual engineering cases, some are due to improper installation or The circuit board of the controller is not treated with three-proof paint, which will cause a short circuit due to rain water flowing into the led street light controller along the external wiring of the controller terminal. Therefore, during construction, attention should be paid to bending the internal connecting wires of the controller terminals into a “U” shape and fixing them, and the connecting wires exposed to the outside are also fixed to a “U” shape, so that rainwater cannot enter and cause the controller to short circuit. You can also apply waterproof glue on the inner and outer line interfaces to waterproof.
The indoor table tennis room originally used 36 1000W lighting light boxes, the glare was serious and unevenly distributed, and the field illumination was less than 100lx, which was not conducive to the development of table tennis. In order to ensure the professionalism of table tennis lighting,CHZ-LIGHTING uses 124 36W professional anti-glare LED panel lights, which are made of special water chestnut plates, UGR<19, and are reasonably arranged above the venue. After testing, the average illuminance of the venue is above 300lx, the uniformity is above 0.6, the light is soft and bright, and there is no glare interference. The healthy eye-protecting light makes the eyes more comfortable.
