In lighting, especially in large-area outdoor lighting, many people tend to use LED explosion-proof floodlights and LED explosion-proof spotlights interchangeably. Even, in close-range lighting, floodlights and spotlights can be used universally. However, there are significant differences between LED explosion-proof floodlights and LED explosion-proof spotlights. Now let’s take a look at the differences between them. LED explosion-proof spotlights are also called (spotlights). Usually, the transparent parts of spotlights form an included angle, so the emitted light is relatively concentrated with a long range, and they are mainly used in concentrated lighting. Both LED explosion-proof spotlights and LED explosion-proof floodlights are widely applicable to hazardous environments, flammable and explosive places (Zone 2), installations and facilities, as well as various indoor and outdoor work lighting areas in industries such as petroleum, chemical engineering, coal, power plants, railways, iron and steel metallurgy, mining, and fire protection. An LED explosion-proof floodlight is a type of LED explosion-proof spotlight. The difference between LED explosion-proof spotlights and LED explosion-proof floodlights lies in the projection angle of the light. However, the reason why many people confuse them now is that there is no standard to distinguish them. LED explosion-proof spotlights have a relatively uniform light beam, that is,

Glare from sports court lamps is also commonly known as dazzling, glaring, or blinding. Glare hazard refers to the uncomfortable visual effect produced in the visual perception system when glare energy acts on the human eye. It includes two types: direct and indirect hazards. In the lighting of badminton and table tennis venues, the main hazard is direct glare. The manifestation of glare hazard from sports venue lamps in the lighting of badminton and table tennis venues is as follows: when athletes move in multiple angles and directions, their eyes only see the dazzling light curtain in a certain field of vision, and cannot see the flying badminton or table tennis ball (the visual target object). Mild glare hazard from sports venue lamps can cause visual discomfort, visual fatigue, and irritability; in severe cases, it can cause temporary visual disability in perceiving the visual target objects (badminton and table tennis balls). Therefore, we must pay attention to avoiding this when decorating sports venues. The quality of sports venue lighting is mainly considered from the following five aspects: 1. Badminton Hall Lighting There are usually three forms of lighting in badminton halls: natural lighting, artificial lighting, and mixed lighting that combines

In the category of lighting tools, LED high-intensity flashlights occupy an important position due to their unique advantages. This type of flashlight uses light-emitting diodes as the light source and features significant characteristics such as environmental friendliness, energy efficiency, and a long service life. With a robust structure, it is widely used in outdoor lighting scenarios and can remain intact even if accidentally dropped. However, despite its excellent durability, minor malfunctions may still occur after long-term use. When an LED high-intensity flashlight suddenly fails to light up, how can we accurately identify the problem and carry out repairs? The following will detail its maintenance and repair methods to facilitate quick troubleshooting. I. Accurately Locating the Cause of the Fault Inspection of the Switch and Circuit Connections First, unscrew the tail of the high-intensity flashlight to expose the negative pole of the battery. Then, use metal objects such as scissors or tweezers to connect the negative pole of the battery to the exposed and non-oxidized part of the flashlight body near the battery, and observe if it lights up. If there is light but the flashlight as a whole does not work, it indicates that the fault lies in the switch,

With the development of society, the high-intensity flashlight industry has increasingly higher requirements for the quality and performance of flashlights. The original plastic shells have gradually been replaced by aluminum alloy shells. Higher-end flashlight shells often use aviation-grade aluminum alloy T6061, just like Sunhighlite’s series of regular flashlights, which all adopt this material. In order to improve the wear resistance and durability of the flashlights, Sunhighlite also performs tertiary hard anodizing treatment on the surface of the flashlights. Next, let’s have a brief talk about the surface treatment process of high-intensity flashlights! It is believed that friends who are familiar with Sunhighlite flashlights must know that Sunhighlite series flashlights will undergo tertiary hard anodizing treatment on their surfaces, so the treated flashlights will have stronger corrosion resistance. In the case of ordinary anodizing treatment, the surface will turn white after multiple frictions; while after tertiary hard anodizing treatment, the flashlight has better corrosion resistance, wear resistance, insulation, etc., and a texture that ordinary anodizing is difficult to achieve. At present, aluminum alloy flashlights on the market will adopt the following two surface treatment methods: ordinary anodizing surface treatment and military-grade tertiary hard anodizing treatment. Most manufacturers tend to choose ordinary

Flashlights with different light colors have unique uses in specific situations and applications. Here are some common colors and their uses:

In modern life, waterproof flashlights, as practical equipment, are widely used in various occasions such as camping, adventure, and emergency response. To ensure the service life and waterproof performance of a waterproof flashlight, regular cleaning is particularly important. This article will delve into how to effectively clean a waterproof flashlight to maintain its ideal waterproof performance, and also provide readers with relevant maintenance skills and precautions.    I. The Structure of Waterproof Flashlights and the Significance of Waterproof PerformanceWaterproof flashlights are usually made of high-density plastic or aluminum alloy materials, and internal components such as batteries, bulbs, and circuit boards are specially designed to withstand humid environments. However, this does not mean that these flashlights can be left without maintenance. After long-term use, dust, salt, and other dirt will accumulate in the seams and openings of the flashlight, affecting its sealing performance, leading to potential moisture intrusion, and reducing its waterproof ability. Therefore, mastering the correct cleaning method is the key to ensuring the long-term use of the flashlight.    II. Preparation for Cleaning a Waterproof Flashlight    III. Cleaning Steps    1. External cleaning     2. Internal cleaning     3. Apply grease    IV. Inspection and Maintenance

Rotary dimming: It has a simple and reliable structure, with little possibility of misoperation and clear gear positions. However, some people think it cannot be operated with one hand. Tail-press dimming: It is simple to operate and low in cost, but the strength of the tail switch is the biggest problem. Especially under the development trend of large current and high power, the instantaneous current of the switch is getting larger and larger, which will gradually shorten the service life of the tail switch and increase the damage rate. Moreover, there is sometimes the possibility of misoperation. Magnetic ring dimming: It is simple to operate and can adjust the light in both forward and reverse directions, but it is not very convenient to operate with one hand. Button dimming: It is simple to operate; pressing once adjusts one gear, with four gears in a cycle. Long-pressing the button enters the hidden strobe mode. It is also convenient to adjust the light when wearing gloves in winter, but the service life of the button is not clear.
