Laser device

Abstract

A laser device comprises a laser unit, a starting switch, a main chip and a control unit connected between the laser unit and the main chip, wherein the laser unit is used for receiving instructions sent by the main chip to transmit laser. The main chip transmits a control signal to the laser unit through the control unit, the control unit is used for disconnecting the laser unit and the main chip while the starting switch detects that a cover body of the laser device is open, and then the laser unit is incapable of obtaining the control signal for transmitting laser, thereby stopping the laser unit transmitting laser. Therefore, the laser can be effectively prevented from leaking to harm human eyes.

Description

laser device technical field The invention relates to a laser device, in particular to a laser device for preventing laser leakage. Background technique Laser (Laser, Light Amplification by Stimulated Emission of Radiation) is a high-energy monochromatic light that can be projected in a certain direction, pass through tissues, and be precisely focused. Lasers are mainly used in laser pens, printers, DVDs and other products, and can also be used in medicine. As we all know, when a certain intensity of laser irradiates the human eye, it will cause retinal tissue burns, and because the retina is a tissue that will not regenerate, it will cause permanent blindness in the human eye. For most of the current products, the protection against laser is directly closed by software. However, due to the existence of factors such as the probability of failure of the software to control the integrated chip. The result is that consumers will directly suffer from laser damage to human ...
