Description

Luminous cover

Technical field

The utility model relates to a kind of lighting device, especially a kind of luminous cover.

Background technology

Some present small instruments and tools are not as all having lighting device on the pen that is used to write and the screwdriver, therefore, at night or the dark place that does not have a lighting condition then can't use, or illuminations fully in addition uses very inconvenient.

Summary of the invention

For overcoming the weak point of above-mentioned prior art, the utility model provides a kind of luminous cover, and this luminous nested structure is simple, dependable performance, can be enclosed within easily and make illumination usefulness on pen or screwdriver or other the similar small instruments and tools.

The utility model is achieved through the following technical solutions: a kind of luminous cover comprises the collar, battery and lead; Be equiped with several electric light sources on the collar, electric light source is connected or is connected in parallel and be electrically connected with battery with lead.

The beneficial effects of the utility model are: simple in structure, volume is little, can with the supporting uses of small-sized object such as pen, screwdriver.

Fig. 2 is the upward view of Fig. 1;

Fig. 3 is the vertical view of battery case among Fig. 1;

Fig. 4 is to use the reference diagram on pen.

Among the figure: 1, the collar, 2, battery, 3, lead, 4, electric light source, 5, battery door, 6, switch.

The specific embodiment

Be described in further detail structure of the present utility model below in conjunction with drawings and Examples.

As shown in drawings, luminous cover is made up of the collar 1, battery case 2 and lead 3, in the collar 1 inboard or the bottom evenly distribute several electric light sources 4 be housed, the collar 1 adopts the rubber ring with Telescopic in the present embodiment, can be enclosed within easily on the small instruments and tools; Electric light source 4 has adopted light emitting diode, also available bulb.Light emitting diode is cascaded by lead 3; Switch 6 is arranged on battery case 2, and there is battery door 5 battery case 2 sides.Power supply in light emitting diode on the collar 1 and the battery case 2 is electrically connected with lead.During use battery case 2 is contained in the object afterbody, the collar 1 is enclosed within on the small instruments and tools, opens switch 6 during use, and the bulb 4 in luminous cover will luminous lighting, can open battery door 6 and change battery very easily when the electric weight of battery is not enough.

Battery also can adopt button cell, makes and overlaps ring joint body, makes luminous cover volume littler.
