Abstract

The utility model discloses an energy-saving lamp comprising a lamp cap, a plastic member and a lamp tube, wherein the plastic member is formed by buckling an upper casing with a lower casing, the inner wall of the upper casing is provided with at least two grooves distributed along the upper casing circumferentially, and the outer wall of the lower casing is provided with a clamping projection matched with the grooves. The upper end of the lower casing is provided with at least one vertical slot and the inner wall of the upper casing is provided with a convex rib matched with the slot. The plastic member of the energy-saving lamp is not easy to disengagement due to the fastened buckling and the integral structure of the plastic member is firmer, thus enriching overall configuration with better sense of beauty.

Description

A kind of electricity-saving lamp

Technical field

The utility model relates to a kind of illuminations, relates in particular to a kind of electricity-saving lamp.

Background technology

Electricity-saving lamp is little with its volume, good looking appearance, and advantage such as easy to use is widely used.The electricity-saving lamp that multiple fluorescent tube forms such as U-shaped, H shape, Double-spiral, single-screw shape successively occurred.Electricity-saving lamp generally is made up of lamp holder, plastic, fluorescent tube, ballast and lead, and wherein plastic mostly is upper shell and lower house connects to form.

China's utility model 02249263.1 disclosed a kind of Electricity-Saving Lamp Moulds One, comprise interconnective upper shell, lower house, the top of upper shell can link to each other with the screw socket of electricity-saving lamp or bayonet socket and electrode, a plurality of location holes are arranged on the lower house, so that the fluorescent tube of electricity-saving lamp just therefrom passes, there is a sunk area at described lower house middle part, and there is thermal insulation layer the centre.But for the electricity-saving lamp of frequent dismounting, upper shell and lower house bonding strength are not enough, easily cause coming off between upper shell and the lower house, thereby cause the shortcoming such as damage, electric wire exposure of fluorescent tube.

Summary of the invention

The utility model discloses the be connected firmly electricity-saving lamp of difficult drop-off, long service life of a kind of plastic.

A kind of electricity-saving lamp comprises lamp holder, plastic and fluorescent tube, and described plastic is fastened by upper shell and lower house and forms, and has at least 2 on the upper enclosure inner wall along the circumferential grooves distributed of upper shell, and the lower house outer wall is provided with the card key that matches with groove.

Described lower house upper end has at least one vertical draw-in groove, and upper enclosure inner wall is provided with the convex tendon that matches with draw-in groove.

The utility model provides Electricity-Saving Lamp Moulds One to fasten fastening difficult drop-off, plastic upper shell and lower house tightly fasten, make the plastic overall structure more firm, can not take place, moulded also create an aesthetic feeling more because of Electricity-Saving Lamp Moulds One connects the insecure accident such as electric leakage electric shock that causes electric wire to expose causing.
