Problems solved by technology

However, the power consumption and heat generated by halogen lamps are still relatively large, which is one of its disadvantages.
At the same time, due to the high power, low voltage, and high current of halogen lamps, the current bulbs of halogen lamps in shadowless lamps use rice bulbs with needle plugs, which have high contact resistance and increased heat generation, which are also the reasons for their short service life and frequent failures.
LED lights consume less power, generate little heat, have good controllability of light source quality, and have a long service life. source co-column purpose

Embodiment Construction

[0016]Surgical shadowless lamps generally use 24V power supply, which is consistent with LEDs mainly 12V and 24V. The overall reflective LED surgery shadowless light source system consists of a power supply (1), a control panel (2), a main light (3), an auxiliary light (4), a display panel (5), a control panel (6), a rechargeable battery (7), a main , auxiliary lamp conversion circuit (8), emergency (switch) circuit (9).

[0017] According to the relevant regulations and requirements of the surgical shadowless lamp, the power supply (1) is a constant current isolated power supply. The 220V AC power is stepped down and rectified and converted into 24V DC power for the column LED lights and rechargeable batteries to ensure the reliable power supply of the LED lights. In addition, the required voltage is provided according to the needs of the turntable motor, control board, and indicator lights.

[0018] The control board (2) includes: 1. main and auxiliary lamp detection circui...

Abstract

The invention relates to a light source system of an integral reflection LED (light emitting diode) shadowless operating lamp. The light source system takes advantages to offset disadvantages, integrates the technical advantages of integral reflection and an LED and overcomes defects. The light source system comprises a light source (1), a control board (2), a main lamp (3), an assistant lamp (4), a display panel (5), a control panel (6), a charging battery (7), a conversion circuit (8) of the main lamp (3) and the assistant lamp (4), and an emergency (switch) circuit (9). A pillar LED lamp is used as a light source for meeting the requirement of integral reflection for the light source, achieving the purposes of energy saving, environment-friendly performance, small thermal generation and long service life. The energy consumption is low, and the battery can be adopted for power supply. The emergency performance of the integral reflection LED shadowless operating lamp is increased by an alternating current and direct current conversion circuit, the conversion circuit of the main lamp and the assistant lamp, and the emergency (switch) circuit.

Description

technical field [0001] The invention relates to a surgical shadowless lamp, more specifically, a light source system for an integral reflective LED surgical shadowless lamp. Background technique [0002] Surgical shadowless lamp is a necessary routine equipment in the operating room of the medical and health system, and its main function is as a special lighting equipment. Surgical shadowless lamps have progressed with the development of light sources, from ordinary shadowless bulbs to halogen bulbs, to today's LED lights; following the development of light sources, they have experienced porous shadowless lamps, reflective shadowless lamps, and LED surgical shadowless lamps. Surgical shadowless lamps are classified from different structures, light sources, reflection methods, and working environments. There are many ways to classify them, so there are many forms and categories of surgical shadowless lamps. 1. From the working environment and installation method, it can be d...
