Problems solved by technology

[0005] The existing LED dental light design scheme uses a large number of LEDs, resulting in a more complex optical system structure and increased manufacturing and maintenance costs
In addition, the utilization rate of light energy is still not high enough

Embodiment Construction

[0019] Such as figure 1 , 2 The optical system of the LED dental light shown in 3 and 4 includes LED, a free-form surface emitter, main and auxiliary brackets, and a screw. The system adopts a symmetrical structure up and down, two parts symmetrical to each other, each part includes a high-power LED lamp 1 or 1' and a free-form reflector 2 or 2', and the two free-form reflectors are connected by the main bracket 6 , the main support 6 is located on the axis of symmetry 3 of the two curved surfaces (such as Figure 5 shown), the main bracket 6 and the sub-support 7 are connected by a screw 10, and two high-power LED lamps 1 and 1' are respectively placed on two symmetrical inclined end faces 8, 9 of the sub-support 7, as Figure 5 As shown, according to the size requirements of the lamp and the principle of ensuring that as much light as possible can be used, determine the vertical distance h between the center position of the LED and the main optical axis 3 and the angle α b...

Abstract

The invention relates to an LED mouth lamp optical system, which comprises LEDs, free-form surface emitters, a main bracket, an auxiliary bracket, and a connecting piece. The system has an up-down symmetrical structure, namely two mutually symmetrical parts; each part comprises a high-power LED lamp and a free-form surface emitter; the two free-form surface emitters is fixed on the main bracket; the main bracket is positioned on a symmetric axis of two curved surfaces; the main bracket is connected with the auxiliary bracket through the connecting piece; and the two high-power LED lamps are respectively arranged on the two symmetrical inclined end faces of the auxiliary bracket. The system has long service life and has obvious energy saving effect compared with the mouth lamp optical system using the conventional light source. Compared with disclosed schemes, the LED mouth lamp optical system of the invention has the advantages of relatively simple structure, high utilization rate of optical energy, and convenient manufacturing so as to facilitate reducing cost.

Description

technical field [0001] The invention relates to a medical device, in particular to an LED oral light optical system. Background technique [0002] A dental light is an auxiliary device commonly used in dental treatment to illuminate the area of ​​a patient's mouth. In order to enable the doctor to observe the patient's teeth clearly and make an accurate judgment, it is necessary to provide sufficient illumination in the patient's oral area. , the illuminance of the patient's eye area should be less than the specified value. The "Pharmaceutical Industry Standard of the People's Republic of China - Dental Light" (No. YY1120-1999) promulgated by the state stipulates the lighting technical indicators of the dental light. [0003] According to the light source used, the existing dental light can be divided into two types, the dental light using the traditional light source and the dental light using the LED. Among them, the dental light using the traditional light source is the...
