Abstract

The utility model relates to a cold light source seat platform formula shadowless light-emitting magnifying glass, it includes seat platform formula shell, the magnifying glass of the upper portion setting in the shell to and light source and power supply unit. The light source is a cold light source which is annularly arranged below the magnifier. The power supply device is arranged on one side of the shell, and the power supply is contacted with the cold light source through the conductive element. The utility model discloses can enlarge the object of seeing clearly under the shining of cold light source light, partial shadow can not appear in the position of enlargeing, has the shadow effect that disappears, and the vision is even clear, long service life.

Description

Cold light source seat stand formula does not have the luminous magnifier of shadow

The utility model relates to magnifier, and particularly a kind of cold light source seat stand formula does not produce the luminous magnifier of shadow.

The luminous magnifier of existing seat stand formula is opened bulb switch in use, scalablely under the irradiation of bulb light sees object clearly, but above being positioned over object the time, the part shadow can appear in the position of being amplified, and the luminance brightness of its light source is lower.What this magnifier used is incandescent lamp bulb, and not only power consumption but also brightness were not good enough.

The purpose of this utility model provides a kind of improved cold light source seat stand formula does not have the luminous magnifier of shadow, and it can amplify and sees object clearly, utilizes the irradiate light of cold light source and can not produce shadow.

A kind of cold light source seat stand formula described in the utility model does not have the luminous magnifier of shadow and comprises seat stand formula shell, the magnifier that top in the enclosure is provided with, and light source and supply unit, and described light source is a cold light source, cold light source is arranged on the below of magnifier in the form of a ring; Described supply unit is installed in shell one side, and power supply contacts with cold light source by conducting element.

The utility model can amplify under the irradiation of cold light source light sees object clearly, and the position of being amplified the part shadow can not occur, and the cold light source colour temperature is correct, and the position of being amplified has stronger luminance brightness and good sharpness.The utlity model has the shadow effect that disappears, vision is evenly clear, long service life.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the cross-sectional view that a kind of cold light source seat stand formula does not have the luminous magnifier of shadow.

Fig. 2 is the vertical view of above-mentioned magnifier.

Fig. 3 is the upward view of above-mentioned magnifier.

Referring to Fig. 1 to Fig. 3, a kind of cold light source seat stand formula does not have the luminous magnifier of shadow and comprises seat stand formula shell 1, the magnifier 2 that the top in shell 1 is provided with, and light source and supply unit.

This light source is a cold light source 3, and cold light source 3 is arranged on the below of magnifier 2 in the form of a ring.

Magnifier 2 is fixedly mounted on top in the shell 1 by set collar 4, and cold light source 3 is then installed in the below of magnifier 2.This cold light source 3 can be a circline, also can be special-shaped fluorescent light, is arranged in the form of a ring in the shell 1.Cold light source 3 is fixedly mounted on the inwall of shell 1 by gland 5.

Battery, battery contact piece 7 and battery cover 8 that supply unit comprises battery chamber 6, installs in battery chamber 6.Supply unit is fixedly mounted on shell 1 one sides by fixed screw 9.Power switch 10 and push button 11 are housed on the supply unit.

Power supply contacts with cold light source 3 by electric wire and conducting element.Under the irradiation of annular cold light source 3, the object that is amplified by magnifier 2 shadow can not occur on every side.
