Abstract
The utility model discloses a bulb, the unique feature of which is that an inner circle is sleeved in the inner hole of the outer circle, the diameter of which is bigger than that of the inner circle and the vacuum is between the inner wall of the outer circle and the outer surface of the inner circle. The utility model is good in luminous effect, small in energy consumption and safe to use.
Description
Affiliated technical field
The utility model relates to a kind of bulb
Background technology
Existing bulb, no matter be socket, or screw, its foam all is one deck structure, and luminescent properties is poor, and energy loss is big.Therefore, resemble the bulb that is used for family, the bulb of using under the mine in use, all can be emitted a large amount of heat.When particularly mine uses bulb down, because of its foam surface temperature height, be the major reason that causes gas explosion under the mine, its surface temperature has reached the ignition point that first is washed.
It is good that the purpose of this utility model provides a kind of illumination effect, and heat energy loss is little, bulb safe in utilization.
For achieving the above object, the utility model bulb is set with interior circle in the endoporus of its cylindrical, and the diameter of cylindrical is greater than the external diameter of interior circle, is vacuum between the outer surface of the inwall of cylindrical and interior circle.
Because the utility model is made up of double-deck circle, between two-layer circle, make vacuum, bulb is luminous generally to be to utilize the electric heating element that is installed in the foam on the main body, therefore, the utility model does not influence luminous to bulb.Because foam is designed to the utility model bulb of double-layer vacuum form, is to make spheroid along the spheroid direction of lamp holder with glass, make the vacuum space of forming a sealing between the two-layer spheroid, do not influence the illumination effect of whole bulb during use.Therefore, the utility model bulb illumination effect is good, safe in utilization.
Description of drawings
Accompanying drawing is depicted as the front half sectional view of the utility model bulb.
Embodiment
As shown in the figure, the external diameter of interior circle [1] is less than the internal diameter of outer circle [2], and the space between 2 circles is a vacuum.
Claims (1)
1, a kind of bulb is characterized in that: be set with interior circle in the endoporus of its cylindrical, the diameter of cylindrical is greater than the external diameter of interior circle, is vacuum between the outer surface of the inwall of cylindrical and interior circle.
