Abstract

The invention discloses a flashlight, which comprises a handle and a bulb, and further comprises a hollow sleeve with a transparent window and a concave mirror, wherein the bulb is fixed at one side end of the handle, the concave mirror is fixed at one end of the sleeve, a first diffuse reflection lens is fixed at the bottom of the concave mirror, and a lamp hole is formed in the diffuse reflection lens; the outer wall of the handle is sleeved with the other end of the sleeve, the first diffuse reflection lens and the side wall of the sleeve form the transparent window of the hollow sleeve, and the sleeve can extend and retract relative to the handle; the bulb is enabled to penetrate the diffuse reflection lens, and is fixed at the center of the concave mirror. As the length of the sleeve is adjusted when needed, and the flashlight can illuminate an object in a wide range, so double benefits can be achieved, the use is convenient and fast, and various conditions of use during nights are satisfied.

Description

Flashlight

Technical field

The present invention relates to can be used for the illuminations that distance-light is regulated, relate in particular to flashlight.

Technical background

At present, people are at general usefulness or traditional flashlight of when illumination, but in order to make the brightness of illumination higher, so the concave mirror of a focusing is installed at bulb position usually, but shortcoming also clearly is exactly the scope of throwing light on has been dwindled greatly, only has a fritter at a distance.So more bothersome when wanting to seek a certain object real night, can only one time strafe, use and be not very convenient.

Summary of the invention

The novel purpose of this use provides flashlight, and it can illuminate in-plant object on a large scale.

Based on above purpose technical scheme of the present invention be: flashlight, comprise handle and bulb, described bulb is fixed in a side of handle, also comprise cannulated sleeve and concave mirror with transparency window, concave mirror is fixed in an end of sleeve, be fixed with the first diffuse reflection eyeglass in the bottom of concave mirror, have lamp hole on the described diffuse reflection eyeglass; The other end of described sleeve is placed in the handle outer wall, and described the first diffuse reflection eyeglass and sleeve lateral wall then consist of the transparency window of cannulated sleeve, and described sleeve can be done stretching motion with respect to handle; So that bulb passes the diffuse reflection eyeglass, be fixed in the center of concave mirror.

Side end at described handle also comprises the second diffuse reflection eyeglass.

Beneficial effect

1) since in needs the length of regulating sleeve, just large-scale illuminating objects so just can kill two birds with one stone, and be easy to use fast, satisfies the situation of multiple use at night.
