Color temperature adjustment device for operating lights

technical field

The invention relates to a color temperature adjustment device of an operation lamp, in particular to a color temperature adjustment device of an operation lamp with high convenience and convenience for color temperature adjustment.

Background technique

Compared with traditional bulbs, light-emitting diodes have absolute advantages, such as small size, long life, low voltage/current drive, not easy to break, mercury-free, good luminous efficiency, and power saving, so light-emitting diodes are used in daily life. The industry has a wide range of applications, such as various indoor lighting devices, backlight modules for display screens, car brake lights, surgical lights, or traffic signs, etc. However, the role of light-emitting diodes as lighting sources has received great expectations , and has made significant progress, so countries and the industry are currently listing this technology as a key technology for strategic development to replace the existing traditional lighting equipment.

At the end of the nineteenth century AD, a British physicist formulated a set of calculation methods for color temperature. The expression of color temperature is expressed in absolute temperature (°K). A black object at 0°K will emit light during heating. As the temperature changes, the color of the light will change. The higher the temperature, the more blue components in the light, and the lower the temperature, the more red components in the light, and the color temperature is expressed by the above method. Generally speaking, the commonly used color temperature range can be divided into warm color light, cool white light and cool color light. The color temperature of warm color light is below 3300K. Warmth or comfort, suitable for homes, residences, dormitories and other places or places where the temperature is relatively low; the color temperature of cool white light is between 3300K and 5300K, and neutral colors make people feel pleasant, comfortable and peaceful because of the soft light. Feel, applicable to shops, hospitals, offices, restaurants, restaurants and other places. The color temperature of cold light is above 5300K, the light source is close to natural light, and it has a bright feeling, which makes people concentrate and makes it difficult to fall asleep. It is suitable for offices, meeting rooms, classrooms, reading rooms of libraries and other places.

Furthermore, the operating light is a very important medical device during surgery, especially when performing general surgery, it provides an important lighting function. For example, it allows doctors to see clearly the peripheral environment of surgery, surgical instruments and positions, the clarity and color of blood vessels and organs in different patients, etc., and each doctor has a different feeling for light, so it is also That is, the preferred color temperature is different, so a surgical light that can adjust the color temperature is needed, so that the doctor will not have unnecessary troubles and problems during the operation, and the familiar color temperature of the light will help the doctor to operate.
