Abstract

The utility model relates to an LED bulb lamp, particularly to a flame-retardant plastic-housing LED bulb lamp. The plastic-housing LED bulb lamp is characterized in that a lamp holder and a plastic housing upper cover are matched in a threaded connection way, the plastic housing upper cover are matched with a light diffusion bottom cover in a clamping connection way, and a driving power source, a heat radiator, an aluminum base board and an LED light source attached on aluminum base board are arranged between the plastic housing upper cover and the light diffusion bottom cover; at least four fixed columns are arranged in the plastic housing upper cover, the driving power source and the heat radiator are respectively matched with the fixed columns in the plastic housing upper cover in a threaded connection way, and the heat radiator and the aluminum base board are arranged to be an integral structure; and one group of LED is welded on the aluminum base board, and the LED group forms the LED light source. The plastic housing upper cover is a flame-retardant plastic housing and is non-conducting, and the internal LED heat radiator insulates heat via air. Compared with the external housing and heat radiator integrated high-power combined bulb lamp, the flame-retardant plastic-housing LED bulb lamp has great advantage at the aspect of safety performance. In case of internal electricity leakages or heating, people can be safe in touching the external housing.

Description

The fire-retardant shell LED bulb lamp of moulding

Technical field

The utility model relates to a kind of LED bulb lamp, is specially a kind of fire-retardant shell LED bulb lamp of moulding.

Background technology

The LED bulb lamp of the extensive use of LED illumination at present generally all is the shell of great power LED composition and the low pressure constant-current drive technology of metal heat sink one; All need increase the AC/DC module; Can not directly directly drive with the 220V civil power; So just increased the cost of LED lighting, designed a kind of can being very important by on-line operation LED bulb lamp of voltage multiplying rectifier high voltage supply under the 220V AC-input voltage increasingly high today energy-conservation the requirement.

The utility model content

To the problem that has cost high safety performance difference in the prior art, the purpose of the utility model is to provide a kind of fire-retardant technical scheme of moulding shell LED bulb lamp of the raising security performance that greatly reduces cost.

The described fire-retardant shell LED bulb lamp of moulding; It is characterized in that comprising lamp holder, mould on the shell cover and light diffusion end cover, described lamp holder covers threaded with moulding on the shell, mould cover and light diffusion end cover snap fit on the shell; Be equipped with driving power, radiator and aluminium base and be attached to the led light source on the aluminium base between covering with the light diffusion end moulding on the shell cover; On moulding shell, be provided with at least four fixed legs in the cover, through bolt and the fixed leg threaded of moulding in covering on the shell, radiator and aluminium base are set to integrative-structure respectively for driving power, radiator; Welding is provided with one group of LED on aluminium base, and this group LED constitutes led light source.

The described fire-retardant shell LED bulb lamp of moulding is characterized in that the described cover of moulding on the shell is to adopt the fire-retardant shell of moulding to process, and is non-conductive, and moulds that the cover radiator inner with it is that air is heat insulation on the shell.

The utility model on-line operation is under the 220V AC-input voltage; Mould on the shell cover and be that fire-retardant to mould shell non-conductive; And it is heat insulation with the LED radiator air of inside; This is that the bulb lamp of the high-power combination of one has very big advantage on security performance than shell and radiator, just in case inner electric leakage or heating occur, it also is very safe that the people runs into shell; The utility model is the curve luminous intensity distribution, and heat radiation is good, is simple and easy to usefulness, and is swift to operate, low energy consumption, and the long-life, high light efficiency, environmental protection, and also elegant in appearance, reliable and stable.

Fig. 2 is the blast structural representation of the utility model;

Among the figure: 1-lamp holder, 2-are moulded on the shell and are covered, 3-light diffusion end cover, 4-driving power, 5-radiator, 6-aluminium base, 7-LED light source.

The specific embodiment

Below in conjunction with Figure of description the utility model is further specified:

The fire-retardant shell LED bulb lamp of moulding comprises lamp holder 1, moulds on the shell cover 2 and light diffusion end cover 3, described lamp holder 1 with mould cover 2 threaded on the shell; Mould on the shell cover 2 and cover 3 snap fit with the light diffusion end; Moulding on the shell cover 2 is to adopt the fire-retardant shell of moulding to process, non-conductive, and moulds that cover 2 radiators 5 inner with it are that air is heat insulation on the shell; Be equipped with driving power 4, radiator 5, aluminium base 6 and be attached to the led light source 7 on the aluminium base 6 between covering 3 with the light diffusion end moulding on the shell cover 2; Cover is provided with at least four fixed legs in 2 on moulding shell, driving power 4, radiator 5 respectively through bolt with mould the fixed leg threaded in the cover 2 on the shell, radiator 5 is set to integrative-structure with aluminium base 6; Welding is provided with one group of LED on aluminium base 6, and this group LED constitutes led light source 7.

The cover of moulding on the shell of the utility model is that fire-retardant to mould shell non-conductive; And it is heat insulation with the radiator air of inside; This is that the bulb lamp of the high-power combination of one has very big advantage on security performance than shell and radiator, just in case inner electric leakage or heating occur, it also is very safe that the people runs into shell.
