Top rated street lights supplier: 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.

Casing: Choice of Material and Engineering Design – Casings combine different metals and optics. Aluminum forms the base, iron or stainless steel forms the connection portion, and polycarbonate or glass makes up the front light cover. Each material exhibits properties relevant to a buyer’s purchasing decision. Most LED roadway light manufacturers choose aluminum, providing 237 W/mf heat transfer capability. LEDs produce heat when operating, which makes metal a great case material. Aluminum, in particular, has good corrosion resistance and is easier to manufacture than other materials. Its 2.7g/cm3 density makes it lighter than the same LED light base made with iron, which has a 7.8g/cm3 density.
Common lighting elements installed in floodlights are Halogen, LED, metal halide, and high-pressure sodium lamps. The type of heating element significantly defines the response and the working hours of a floodlight. Applications: Residential: Backyards, rooftops, courtyard, lawn areas; Commercial: Parking lots, outdoor advertising, building illumination; Industrial: Large warehouses, manufacturing setups, process industry halls; Public: Streetlights, metro stations, airports, train halls; Sports: Stadium, football grounds, tennis courts, and more. Based on feedback, buyers prefer them for outdoor field lighting and security fence lighting due to their bright white light. However, they usually generate a lot of heat and are less energy efficient than their LED counterparts.
The power of the High Bay Led Lights is only 20% of the sodium lamp, which is equivalent to the 100W LED high bay lamp can replace the 250W sodium lamp, especially in line with the “green low carbon” proposed by the state. Applicable occasions: shipyards, mines, workshops, factories, warehouses, highway toll stations, gas stations, large supermarkets, exhibition halls, stadiums and other places where industrial and mining lighting is required.

Street lights or street lamps are helpful as they illuminate roadways, parking lots, sidewalks, and other public areas where people gather. Apart from improving driving safety, street lights also enhance the security of a site by improving vision in poor light conditions. Most of these street lights are often used with other traffic safety equipment that enhances visibility and removes all the obstacles in darkened areas. You need to understand that the primary function of street lights is to illuminate rooms or objects that would otherwise be in darkness or out of focus, especially at night.
The waterproof problem of the lamp: How should the lamp holder be waterproof? Many street lamp manufacturers take this into consideration when they produce LED street lamp caps. Most street lamp caps are waterproof. Not only that, many led outdoor street lights have protection grades of IP65 or IP66, which can completely prevent dust from intruding, and will not seep in rainstorms, and are not afraid of bad weather. However, it cannot be generalized. The waterproof performance of LED street lights also depends on the manufacturing capacity and level of street lamp manufacturers. Large manufacturers can be more trustworthy, but small workshops may not be able to guarantee the quality. It is recommended to confirm the test report of the product before purchasing.
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.
