Abstract

The utility model discloses an energy saving electronic fluorescent lamp, which has a good heat dissipation condition. The utility model is characterized in that the lamp tube and the ballast in a general electronic energy saving fluorescent lamp are divided into two sealed mould cavities, an insulating plate is arranged between the lamp tube and the ballast to isolate the heat generated by the lamp tube, the heat can be timely emitted through a metallic heat dispersion case, and the heat can not be passed to the part of the ballast. The stable performance of electronic components can be protected, and the problem that the temperature rise of a large power electronic energy saving fluorescent lamp is too high to influence the lighting performances can be solved.

Description

Energy-saving electronic fluorescent lamp

The utility model relates to a kind of electronic energy-saving fluorescent.

At present, electronic energy-saving fluorescent is because its superior performance, colour temperature is good, the illumination lumen is big, the fluorescent tube long service life, energy savings, price is than characteristics such as incandescent lamp is suitable, the trend that replaces incandescent lamp is arranged, but because existing electronic energy-saving fluorescent is for the effect that reaches dustproof and Electrical Safety and need be easy to again make, nonmetal lamp housing and the lampshades of adopting form full-closed structure more, heat dispersion is relatively poor, because a large amount of heats that fluorescent tube produces, make the interior temperature of lamp of enclosed construction higher, cause electronic ballast components to lose efficacy so that the ballast damage, have a strong impact on the useful life and universal use of electronic energy-saving fluorescent.The patent No. is CN88205947.5's the electronic energy-saving lamp of shell " band heat radiation " Chinese patent, a kind of way of heat radiation has been proposed, solved the problems of excessive heat of general electronic energy-saving fluorescent, but its radiating effect is not enough for powerful electronic energy-saving fluorescent.

The purpose of this utility model provides a kind of improved electronic energy-saving fluorescent, electric ballast and fluorescent tube are separated effectively, the heat that fluorescent tube is produced gave out outside the lamp rapidly before passing to electric ballast in time, thereby guaranteed that electric ballast can work under the environment of safety, prolonged stream time and the useful life of electronic energy-saving fluorescent.

The utility model is realized in the following manner: by thermal insulation board and heat dissipation metal shell electric ballast and lamp socket, fluorescent tube, the lampshade of electronic energy-saving fluorescent is divided into two cavitys up and down, between thermal insulation board and the heat dissipation metal shell bigger air space is arranged, having only less area is direct contact.Strengthened effect of heat insulation, the heat overwhelming majority who produces when making lamp works gives out outside the lamp by heat dissipation metal shell and lampshade, and thermal insulation board will make heat be difficult to import into electric ballast place cavity, thereby the assurance electric ballast is worked under the environment of safety.

The utility model is owing to adopted thermal insulation board and the insulating layer structure of heat dissipation metal shell composition, radiating effect is improved greatly, prevented that temperature is gathered in the lamp, stoped the heat transferred electric ballast again, both satisfy dustproof and safe requirement, guaranteed the long-time steady operation of lamp again, prolonged useful life effectively, and simple in structure, cost is lower.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the schematic diagram of electronic energy-saving fluorescent.

Fig. 2 is the schematic diagram of heat dissipation metal shell.

Fig. 3 is the schematic diagram of thermal insulation board.

As shown in the figure, two pillars 10 that symmetry is arranged on the lamp holder 3 that connects with external power source, the lamp housing 11 are equipped with on the top of lamp housing 11, can be by screw 6 with electric ballast 9, thermal insulation board 8, lamp socket 7, heat dissipation metal shell 4 are fixed on the pillar 10, and fluorescent tube 2 is contained on the lamp socket 7, and lampshade 1 is connected on the chimb 5 of heat dissipation metal shell 7 by lampshade boss 12, at Fig. 1 is can clearly be seen that, constitutes upper impression by lamp holder 3, lamp housing 11, electric ballast 9; Form lower impressions by lamp socket 7, heat dissipation metal shell 4, fluorescent tube 2, lampshade 1.Separated by thermal insulation board 8 in the middle of the last lower impressions, the heat that produces when making fluorescent tube 2 work gives out the outside in time by heat dissipation metal shell 4 and lampshade 1, has avoided heat to enter upper impression, thereby has guaranteed that the electronic devices and components in the electric ballast 9 can normal steady operation.

Fig. 2 is a heat dissipation metal shell schematic diagram.Have screwing through hole 14 and lamp socket through hole 13.

Fig. 3 is the thermal insulation board schematic diagram.Have screwing through hole 14 and wire guide 15 on it, the position of wire guide 15 and quantity can change with actual needs, but have one at least.Thermal insulation board adopts the partiting thermal insulation made.
