What exactly do color temperature, lumens, candelas, and color rendering mean?

What is luminous intensity? It is the unit of luminous intensity, used to measure the luminous ability of a light source in a specific direction. For example, the luminous intensity of car high beams is usually more than tens of thousands of candelas, which can illuminate the road ahead at a long distance, while the luminous intensity of ordinary flashlights may only be a few hundred candelas. Applications: In road lighting design, it is necessary to reasonably set the luminous intensity of street lamps according to factors such as road grade and traffic flow to ensure that the road has sufficient brightness and uniformity. In stage lighting design, lamps with different luminous intensities are also used to create various lighting effects according to the needs of the performance.What is illuminance? Illuminance (lux, lx) refers to the brightness when light hits an object. It represents the luminous flux per unit area and affects the perception of an object’s brightness. The farther the light source is from the object, the faster the illuminance decreases. A flashlight appears dimmer from a distance than up close precisely because the illuminance becomes lower. What is color rendering index? Color rendering refers to the ability of

How to Prevent Fires Caused by Ordinary Lighting Fixtures?

In the production and operation of any factory or enterprise, lighting is an essential link, as it is crucial to employees’ work efficiency and production safety. However, because the connection between factory lighting and enterprise production safety is implicit, it is often easily overlooked by managers. Take ordinary fluorescent lamps as an example. They consist of tubes, starters, ballasts, lamp holders, etc. The cause of fire in fluorescent lamps is that the ballast, composed of an iron core and coils, consumes electricity and generates a certain amount of heat. If the ballast is poorly manufactured, has poor heat dissipation, is mismatched with the tube, or works for too long, its internal temperature will rise, damaging the insulation layer of the coils and causing inter-turn short circuits. This produces high temperatures, which can ignite the dust accumulated on the ballast and surrounding combustibles. Currently, LED explosion-proof lighting is the most widely used in factory lighting. LED explosion-proof lighting can be used in hazardous locations with flammable gases and dust, as it can prevent arcs, sparks, and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment. Its protection level is generally IP65

What’s the Difference Between LED Explosion-Proof Floodlights and LED Explosion-Proof Projectors?

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,

How much do you know about sports venue lighting?

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

What are the special features of a flashlight after tertiary hard anodizing?

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
