Abstract

The utility model relates to a cold light lamp, including a case, a mounting seat, a concave mirror, a light bulbs, a first convex lens, a second convex lens, a joint and an optical fiber, wherein the mounting seat is provided inside the case; the concave mirror, the light bulb, the first convex lens and the second convex lens are provided in sequence on the mounting seat; the bulb is provided at the focus of the concave mirror and the first convex lens, the second convex lens is provided beyond the double focal-length of the first convex lens; the joint is provided on the case and simultaneous at the focus point of the second convex lens, the light ray is connected to the joint; a first convex lens is added in the utility model, so that the light of the bulb deviated from one surface of the concave mirror are congregated on the second convex lens through the first convex lens, to enter in the optical fiber to further improve light use ratio.

Description

A kind of cold light lamp

Technical field

The utility model relates to a kind of cold light lamp, and particularly a kind of optical fiber, cold light lamp that leaded light efficient is high of being applied to belongs to the optical fiber technology field.

Background technology

Our employed light at present, for example daylight, light all result from thermal light source, because the transmission of light is a straight line, direct light irradiation less than the place see thing, particularly will see the object in aperture, the hole clearly, ordinary light source just is difficult to accomplish that cold light has its specific use, for example in biological scientific research, shine bacterium with cold light, bacterium can be not dead, uses in medical diagnosis, and patient does not have burn feeling, can not produce fear or the like, the utilization rate of the light of cold light lamp commonly used is lower.

The utility model content

The purpose of this utility model is to provide a kind of optical fiber, cold light lamp that leaded light efficient is high of being applied to.

For achieving the above object, this novel technical solution is finished like this: a kind of cold light lamp; Comprise casing, mount pad, concave mirror, bulb, first convex lens, second convex lens, joint, optical fiber; Described mount pad is arranged on the inside of casing; Described concave mirror, bulb, first convex lens, second convex lens are successively set on the mount pad; Described bulb is arranged on the focus of the concave mirror and first convex lens; Described second convex lens are arranged on beyond 2 times of focal lengths of first convex lens; Described joint is arranged on the casing, and the while is at the focus place of second convex lens; Described light links to each other with joint.

Because the utilization of technique scheme, the utility model compared with prior art has following advantage:

The utility model has been set up first convex lens, thereby the light that can make bulb deviate from the concave mirror one side gathers on second convex lens by first convex lens, thereby enters optical fiber, has improved the utilization rate of light.

Description of drawings

Operation further specifies to the utility model below in conjunction with drawings and Examples:

Fig. 1 is the three-dimensional outline drawing of cold light lamp of the present utility model;

Fig. 2 is the cutaway view of cold light lamp of the present utility model;

Wherein: 1, casing; 2, mount pad; 3, bulb; 4, concave mirror; 5 first convex lens; 6, second convex lens; 7, joint; 8, optical fiber; 9, power switch; 10, indicator lamp.

The specific embodiment

Below in conjunction with embodiment principle of the present utility model and feature are described in detail:

Cold light lamp shown in accompanying drawing 1,2, a kind of cold light lamp; Comprise casing 1, mount pad 2, concave mirror 4, bulb 3, first convex lens 5, second convex lens 6, joint 7, optical fiber 8; Described mount pad 2 is arranged on the inside of casing 1; Described concave mirror 4, bulb 3, first convex lens 5, second convex lens 6 are successively set on the mount pad 2; Described bulb 3 is arranged on the focus of the concave mirror 4 and first convex lens 5; Described second convex lens 6 are arranged on beyond 2 times of focal lengths of first convex lens 5; Described joint 7 is arranged on the casing 1, and the while is at the focus place of second convex lens 6; Described light links to each other with joint.Also be provided with power switch 9 on the described casing, be used for controlling bulb 3, when bulb 3 was lighted, the indicator lamp 10 on the casing was bright.

Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.

Claims

1. cold light lamp; Comprise casing, mount pad, concave mirror, bulb, first convex lens, second convex lens, joint, optical fiber; It is characterized in that: described mount pad is arranged on the inside of casing; Described concave mirror, bulb, first convex lens, second convex lens are successively set on the mount pad; Described bulb is arranged on the focus of the concave mirror and first convex lens; Described second convex lens are arranged on beyond 2 times of focal lengths of first convex lens; Described joint is arranged on the casing, and the while is at the focus place of second convex lens; Described light links to each other with joint.
