Problems solved by technology

Therefore, some manufacturers have added the warning words "prohibited to be installed in reflectors below 5 inches" on the packaging boxes of their energy-saving lamp products, which really limits the application range of energy-saving lamps.
It is not conducive to the promotion of using energy-saving lamps to directly replace incandescent bulbs

Embodiment Construction

[0020] Below in conjunction with all accompanying drawings the present invention will be further described, and preferred embodiment of the present invention is: see appended figure 1 To attach Image 6 , the energy-saving lamp described in this embodiment includes a lamp tube 1, a lamp housing 2, and an electronic ballast 3, wherein the electronic ballast 3 is located in the lamp housing 2, and the lamp tube 1 surrounds the outer surface of the electronic ballast 3 On the lamp housing 2, the lamp housing 2 is composed of upper and lower housings 5, 4 that are fastened to each other. After the buckling, the upper and lower housings 5, 4 have inner side walls and outer side walls, and a partition is formed between the inner and outer side walls. The size of the heat chamber 6 and the heat insulation chamber 6 can be adjusted as required. The outer fastening area is provided with a lamp tube installation groove 7 for installing the lamp tube 1. The lamp tube 1 is installed in t...

Abstract

The invention provides an energy-saving lamp with an air insulating cavity. The energy-saving lamp comprises a lamp tube, a lamp housing and an electronic ballast, wherein the electronic ballast is arranged in the lamp housing; the lamp tube surrounds the lamp housing which is outside the electronic ballast; the lamp housing is composed of an upper housing and a lower housing which are fastened to each other; the fastened upper housing and lower housing have an inner side wall and an outer side wall; and a closed insulating cavity filled with air is formed between the inner side wall and the outer side wall. The scheme provided by the invention utilizes the heat insulation principle of air cleverly as follows: when the heat generated by the lamp tube is transferred to the inside of the lamp housing, the heat firstly passes through the outer wall of the lamp housing and heats air in the air insulating cavity, and secondly passes through the inner sleeve of the electronic ballast to affect the electronic ballast. As air has higher thermal resistance, the time that the heat of the lamp tube is transferred to the electronic ballast can be greatly prolonged, the electronic ballast can not be affected by high external temperature in long-term operation and the application of the energy-saving lamp can not be limited.

Description

Technical field: [0001] The invention relates to the technical field of lamps, in particular to an energy-saving lamp with an air-insulated cavity. Background technique: [0002] At present, when making compact energy-saving lamps, the lamp tube is usually surrounded by the lamp housing outside the electronic ballast. After adopting this method, when the volume of the lamp is effectively reduced, the lamp tube is also very close to the electronic ballast. The temperature generated by the lamp tube is very high when it is working. Such a high temperature will directly act on the electronic ballast after passing through the lamp shell, and the electronic ballast itself will also emit a certain amount of heat when it is working. The high temperature transmitted, generally work for about half an hour, the electronic ballast will be burned due to the high temperature. This situation is especially likely to occur when energy-saving lamps are installed in small-caliber reflectors....
