Abstract

The utility model belongs to the technical field of lighting and relates to an illuminating lens device capable of focusing. The illuminating lens device comprises a dimming lens (1), a telescopic shell, waterproof rings (2) and a light source (5) and is characterized in that the dimming lens (1) is arranged at the upper end of the telescopic shell, the light source (5) is connected at the lower end of the telescopic shell, and two water rings (2) are arranged at the upper end and the lower end of the telescopic shell respectively. The illuminating lens device has a simple structure; and light emitted by the light source can change focus through the lowering and raising of the telescopic shell so as to ensure that the light emitting angle can be changed, and the positive illumination of the light source is changed so as to overcome the shortcoming that a single lens angle is fixed so that the lighting angle is not capable of being controlled.

Description

A kind of illuminating lens device of adjustable focus

Technical field

The utility model relates to a kind of illuminating lens device of adjustable focus, belongs to lighting technical field.

Background technology

Along with the continuous progress of science and technology, lighting engineering has obtained development widely.Because the LED light fixture has excellent energy-saving effect, advantages such as long service life make the LED lamp become the main product of lighting field rapidly.

But existing lighting device, mostly its structure is single lens, the lens fixed angle, therefore uncontrollable lighting angle needs to seek a kind of novel illuminating lens device simple in structure, can address the above problem.

Summary of the invention

In view of the defective that prior art exists, the purpose of the utility model is the illuminating lens device that a kind of adjustable focus will be provided, and it can effectively solve the general lighting design factors and fix, the problem of uncontrollable lighting angle.

For realizing above-mentioned purpose, the technical solution that the utility model adopted:

A kind of illuminating lens device of adjustable focus; Form by light modulation lens, flexible shell, water proof ring and light source; It is characterized in that: the upper end of flexible shell is equipped with the light modulation lens, and the lower end of flexible shell connects light source, at the two ends up and down of flexible shell two water proof rings is installed all.

Said flexible shell is made up of flexible shell in outside and inner flexible shell, the reduction through regulating flexible shell and raise the distance of controlling lens and light source.

Said flexible shell control lens and light source flexible adjustment in the distance range of 0mm-100mm.

After adopting such scheme, compare with existing apparatus and the utlity model has following beneficial effect:

The utility model is simple in structure, the reduction that utilizes flexible shell with raise, can make the light source zoom that emits beam, make light send angle and change, thereby the positive illumination of light source is changed, solve the defective of the uncontrollable lighting angle of single lens fixed angle.

Fig. 1 is a kind of illuminating lens apparatus structure sketch map of adjustable focus;

Among the figure: 1, light modulation lens, 2, water proof ring, 3, outside flexible shell, 4, inner flexible shell, 5, light source.

The specific embodiment

A kind of illuminating lens device of adjustable focus; Form by light modulation lens 1, flexible shell, water proof ring 2 and light source 5; The upper end of flexible shell is equipped with light modulation lens 1, and the lower end of flexible shell connects light source 5, at the two ends up and down of flexible shell two water proof rings 2 is installed all.

Said flexible shell is made up of flexible shell 3 in outside and inner flexible shell 4; Reduction through regulating flexible shell with raise the distance of controlling light modulation lens 1 and light source 5, said flexible shell control light modulation lens 1 and light source 5 flexible adjustment the distance range of 0mm-100mm in.The flexible shell of the utility model utilization reduces and raises, and can make light source 5 zoom that emits beam, and makes light send angle and changes, thereby light source 5 positive illumination are changed.

The utility model has solved the problem of the uncontrollable lighting angle of single lens fixed angle of ordinary lens.
