Surgical shadowless lamp is a common medical device among our medical staff. Compared to some parameters such as illumination and color temperature, which you may be very familiar with, you may not be very familiar with the heat dissipation method of surgical lamps. Today, we will introduce the heat dissipation system of surgical shadowless lamps.
A surgical lamp with good convective heat dissipation effect. A surgical light with good heat dissipation, normal illumination, and long service life can be provided as a surgical shadowless lamp. The surgical light with this device includes a housing, a reflector with an opening at the top, heat-insulating glass, a handle, and a light source component; The light source component includes a light source and a heat shield body with an opening and a bottom vent hole; The reflection mirror installed inside the casing forms a convection channel with the casing; The insulation glass sandwiched between the reflector and the ring cover forms a partition space between the reflector and the reflector; Multiple gaskets are installed between the heat-insulating glass and the reflector to form multiple channels that connect the convection channel and the partition space.
To prevent dust from entering and affecting the lighting effect or infection, the sealing requirements for surgical lights are generally very high. However, the heat dissipation of traditional surgical lamps usually adopts an open design. As for the publicly disclosed ‘improved structure of lamp heat dissipation and fixing device’, it is attached to the lamp chassis with through holes, and two ventilation plates are installed in the fixed seat on the chassis, with through holes for air circulation on the ventilation plates, and a fan is installed below the through holes. In this way, the external air is input through a fan to achieve heat dissipation effect. The enclosed lighting system adopts a closed type, with a bracket fixed to the metal tube at the opening above the heat shield, and the metal tube is located directly above the bulb and extends downward to near the bulb. The heat of the light bulb is guided upwards through a metal tube, and dissipated from the top and periphery of the outer cover. Surgical lights with this heat dissipation structure have also been proposed to dissipate heat through the outer cover and heat-insulating glass, or through the top of the cover. However, surgical lights with this heat dissipation structure only consider that the heat-insulating cover can block most of the sensible heat of the light bulb, without considering the radiation heat generated by the light bulb. Therefore, they can only partially dissipate heat and cannot effectively reduce the temperature of the surgical light significantly.
Our company aims to produce surgical lights that have good heat dissipation, can maintain normal illumination, and have a long service life.
The heat dissipation of most products consists of an outer cover, a reflector, heat-insulating glass, a handle installed in the center of the heat-insulating glass, and a light source installed on the handle; The outer cover includes a top cover part and a ring cover part connected to the top cover part; The top of the reflector has an opening; The light source component includes a light source and a heat shield that covers the light source; The heat shield of the lamp component is equipped with an opening facing the top of the reflector and a bottom vent hole; The reflector system is installed inside the outer cover and forms a convection channel between it and the outer cover; The heat-insulating glass is sandwiched between the reflector and the step of the outer cover, and forms a partition space between the reflector and the outer cover; Multiple gaskets are installed between the heat-insulating glass and the reflector to form multiple channels that connect the convection channel and the partition space.
