Description

Medical reflective cup

Technical Field

The invention relates to a lamp, in particular to a reflecting cup for a medical lamp.

Background

Operation shadowless lamps, examination lamps, operating room integral lighting systems and the like are conventional and necessary equipment for hospitals, and the use of medical lighting systems is a necessary working condition and premise in numerous medical works.

An oral light is a commonly used accessory in dental treatment for illuminating an area of a patient's mouth. In order to enable a doctor to clearly observe the teeth of a patient and make an accurate judgment, sufficient illumination needs to be provided in the oral cavity area of the patient, and meanwhile, in order to avoid injuring the eyes of the patient, the illumination range is limited to the oral cavity part, and under a normal use condition, the illumination of the eye area of the patient is smaller than a specified value. The oral lamp (number YY1120-1999) promulgated by the nation, the standards of the Chinese medicine industry, oral lamps, stipulate the lighting technical indexes of the oral lamps. The existing oral cavity lamps can be classified into two types according to the light source used, an oral cavity lamp using a conventional light source and an oral cavity lamp using an LED, wherein the oral cavity lamp using a conventional light source is most widely used at present. The traditional halogen lamp light source has lower luminous efficiency, large heat emission and shorter service life. Moreover, the conventional light source has a large size and a large light radiation angle, so that the light utilization rate of the lamp using the conventional light source is not high. The power of the traditional oral lamp light source is about 50W, the luminous flux in the effective area on the illuminated surface is about 72lm, and the efficiency of the whole lamp is only 1.44 lm/W.

The design scheme of the existing LED oral cavity lamp uses a large number of LEDs, so that the structure of an optical system is complex, and the manufacturing and maintenance cost is increased. In addition, the efficiency of light energy utilization is still not high enough.

In order to overcome the above problems, a medical reflecting cup has been developed.

Disclosure of Invention

In order to overcome the problems, the invention provides the medical reflective cup which can be matched with a plurality of XPG light sources, has uniform light spots, no astigmatism, no black spots and no shadow, and can furthest exert the light utilization rate of the LED.

The technical scheme provided by the invention is as follows:

the utility model provides a medical treatment anti-light cup, includes anti-light cup body and mount pad, and anti-light cup body's opening is oval, and anti-light cup body's cup chamber is the free curved surface of concave form, and anti-light cup body open-ended both sides are connected with the mount pad.

As a preferred scheme, the reflection cup body and the mounting seat are both finished by one-time demoulding of PC materials.

Preferably, the mounting seat is U-shaped.

Preferably, two internal thread holes are formed in the end of the mounting seat.

Preferably, the free-form surface is composed of a parabolic mirror. Parabolic mirrors come from a parabolic shaped geometry: if the angle of incidence on the inner surface of the collector is equal to the angle of reflection, any incident light parallel to the optical axis of the disk surface will be reflected to the focal point. Because many types of energy can be so reflected, parabolic reflectors can collect and concentrate the energy entering the reflector to a particular angle. Similarly, the energy radiated from the focal point of the disk surface can be transmitted as a beam parallel to the axis of the disk surface.

Preferably, the surface of the reflecting cup body is provided with a reflecting coating.

Preferably, the light reflecting coating is formed by heating and melting aluminum metal to evaporate in a vacuum state, and condensing aluminum atoms on the surface of the polymer material to form an extremely thin aluminum layer. Vacuum aluminizing requires that the surface of the base material is smooth and flat and has uniform thickness; proper stiffness and friction coefficient; a surface tension greater than 38 Dyn/Cm 2; the heat performance is good, and the heat radiation and condensation heat of the evaporation source can be resisted; the water content of the base material is less than 0.1%. The process requirements are as follows: the vacuum degree is not lower than 103PA, so that the phenomenon of brown stripes or uneven aluminum layer thickness is avoided; the tension of the system is controlled, and a cooling system is started to avoid the stretching deformation of the film caused by heating; accurately controlling the coiling speed (280-320 m/min), the aluminum conveying speed (0.4-0.7 m/min) and the heating current of the evaporation boat to obtain the aluminum layer thickness (100-300A DEG) required by the product; the film can be coated with a certain amount of primer in advance, and the primer is fully dried and then vacuum-plated with aluminum, so that the binding force between the aluminum layer and the film can be improved. Then coating a certain amount of protective resin on the aluminum film to prevent the aluminum layer from oxidative deterioration. The aluminum-plated film formed by the process is friction-resistant and is not easy to deteriorate.

Preferably, the base material used for the reflective coating is polyester, polypropylene, polyamide, polyethylene or polyvinyl chloride.

Compared with the prior art, the invention has the following advantages:

1. the medical reflective cup is finished by adopting PC material through one-time demoulding, has high optical precision and no deformation memory, adopts high-tech vacuum aluminizing, has excellent metal luster, and has light reflectivity of more than 95%;

2. the medical reflection cup can be matched with a plurality of XPG light sources, has uniform light spots, no astigmatism, no black spots and no shadow, and can furthest exert the light utilization rate of the LED;

3. the medical reflective cup adopts high-precision aspheric optical design;

4. the medical reflective cup meets the national and export standards, adopts anti-static shockproof packaging, and meets the ROHS environmental protection requirements through SGS authentication.
