Description

A kind of incandescent lamp that has inner Halogen lamp LED

Technical field

The utility model relates to a kind of lighting, specifically is meant a kind of incandescent lamp that has inner Halogen lamp LED.

Background technology

Advantage simple in structure, with low cost, that brightness is easy to adjustment and control and color rendering good (Ra=100) that incandescent lamp commonly used at present has, be that average family or communal facility are all generally used incandescent lamp in long-time, yet incandescent lamp also exists many fatal shortcomings: short as useful life, luminous efficiency is low (only have 12%-18% can be converted into luminous energy, and remainder all scattering and disappearing with the form of heat energy), colour temperature low (2700-3100K).

Halogen lamp LED improves on the basis of incandescent lamp and obtains, and almost be 3 times of incandescent lamp its useful life, can be operated under the higher temperature owing to filament simultaneously, thereby obtain higher brightness, higher colour temperature and the luminous efficiency of Geng Gao.

As Fig. 1, shown in Figure 2 is the incandescent lamp that has inner Halogen lamp LED, it comprises lamp holder 1, glass stem 2, a pair of power lead 3, Halogen lamp LED 4 and cell-shell 5, cell-shell 5 and glass stem 2 are installed on the lamp holder 1, power lead 3 is installed on the glass stem 2, Halogen lamp LED 4 has a pair of leading foot 41, press from both sides flat 42, be fixedly installed on a pair of molybdenum sheet 43 in the folder flat 42, with this wire foot 44 that molybdenum sheet 43 is linked to each other respectively, luminous element 45, foam 47 and the burned tip column cap 46 straight up that is positioned at foam 47 tops, luminous element 45 is positioned at foam 47, its two ends link to each other with a pair of wire foot 44 respectively, the a pair of leading foot 41 of Halogen lamp LED 4 is welded to connect with power lead 3 respectively, and power lead 3 plays the effect of supporting Halogen lamp LED 4 and giving luminous element 45 conductions.

The above-mentioned incandescent lamp that has inner Halogen lamp LED has factory in useful life, characteristics that luminous efficiency is high, but because the manufacture craft of Halogen lamp LED 4 needs, make foam 47 tops of Halogen lamp LED unavoidably can leave compact structure and burned tip column cap 46, the light that luminous element 45 is sent is difficult for penetrating closely knit top, in the field of illumination, can stay illumination shade among a small circle, make luminous element 45 the illumination shadow region occur, influence illuminating effect.

The utility model content

The purpose of this utility model provides a kind of incandescent lamp that has inner Halogen lamp LED, and this incandescent lamp shadow region of not throwing light on substantially has good illuminating effect.

Above-mentioned purpose of the present utility model realizes by following technical solution: a kind of incandescent lamp that has inner Halogen lamp LED, it comprises lamp holder, glass stem, power lead, Halogen lamp LED and cell-shell, cell-shell and glass stem are installed on the lamp holder, power lead is installed on the glass stem, described Halogen lamp LED comprises leading foot, press from both sides flat, luminous element and foam, the leading foot of Halogen lamp LED is fixedlyed connected with power lead, luminous element is positioned at foam, the foam top has the burned tip column cap, it is characterized in that: the top of the foam of described Halogen lamp LED and burned tip column cap are to have the frosted top diffuse reflection function and that frosted can printing opacity forms, the height of the least significant end at described frosted top is lower than the height of luminous element least significant end, has difference in height between the two.

Luminous element can adopt multiple structure in the utility model:

Structure one: described luminous element is the filament of along continuous straight runs horizontally set, has the height difference H 1 of 1～2mm between the height of the least significant end at the height of described luminous element least significant end and frosted top.

Structure two: described luminous element is along the vertical filament that is provided with of vertical, has the height difference H 2 of 1～2mm between the height of the least significant end at the height of described luminous element least significant end and frosted top.

Structure three: described luminous element is the filament of bending, has the height difference H 3 of 1～2mm between the height of the least significant end at the height of described luminous element least significant end and frosted top.

Compared with prior art, the top of the foam of Halogen lamp LED and burned tip column cap are the frosted top that frosted forms in the utility model, this frosted top itself has transmittancy, and the light that the frosted top can make luminous element send forms diffuse reflection, eliminating closely knit top and the burned tip column cap of foam shuts out the light, and the leading foot of Halogen lamp LED, power lead, the supporting bracket illumination shade that shuts out the light etc. and in the field of illumination of luminous element, to stay, eliminate luminous element and the illumination shadow region occurs, have good illuminating effect.
