What are the detailed descriptions of the types of office lighting fixtures?

Lamps are generally used for night lighting, but many offices also use lighting lamps during the day. Because the general office requires strong light, if the light in the compartment is too strong, it will feel dim, so the use of lighting lamps is not only at night, but also often used during the day. There are many requirements for office lighting equipment, so it is best to choose soft lighting to avoid visual fatigue caused by long-term work. There are many kinds of lamps suitable for office use. Here are some common types.

Uniform diffusion lamp

This kind of lamps can make all light diffuse evenly in all directions, with beautiful shape and even and soft light, but the light efficiency is not high and the loss is more. It is most suitable for space lighting without special requirements, such as hallways and aisles.

Semi-indirect lamp

This kind of lamp can make 90% luminous flux project to the ceiling and the upper end of the wall, forming a big glossy surface. Although its brightness is not high, the light in the whole illuminated space is evenly distributed and there is no obvious shadow. Because of the large optical loss, it is necessary to increase the luminous flux by 50%- 100%. Semi-indirect lights can be used in public places such as conference rooms.

Direct lamp

Direct light often uses white enamel, aluminum plate and mirror glass plated with mercury as lampshades, and makes full use of the light, so that 90%- 100% of the light is projected onto the working surface or clothes, thus forming a strong contrast between the illuminated area and the non-illuminated area. According to the light distribution curve, lighting can be divided into ultra-deep illumination type, deep illumination type, wide illumination type, illumination type and uniform illumination type. Direct light is generally prone to glare, which will lead to visual discomfort. Suitable for small offices and reception rooms.

Semi-direct lamp

Semi-direct light can concentrate 60%-90% luminous flux on the working surface, and can also properly illuminate the space environment, improve the indoor brightness ratio, make the light in the whole room soft and produce good lighting effect. Suitable for public office space.

Indirect lamp

Indirect lights reflect all the light to the ceiling to work. The light is even and soft, which can avoid glare, but the light loss is large. They are usually used in combination with other types of lamps as auxiliary light sources.

The above lamps are common and suitable for office use. In general, offices are used to chandeliers, and the lights are more uniform and divergent. The lighting of semi-indirect lamp is very uniform and has no shadow, which is especially suitable for meeting rooms. Direct lighting is generally used in small office areas with concentrated lighting, which is suitable for office use at night. The lamps and lanterns in the office must be carefully selected. Good lamps will not make eyes feel tired and can improve work efficiency.
