Abstract

The utility model discloses a high-light effect halogen lamp, which comprises a lamp holder, a glass shell, a stem and a lamp filament, wherein the glass shell comprises a neck-shaped head, a first reflection part, a second reflection part and a light-emitting bottom which are jointed, the inner surface of the middle of the neck-shaped head to the first reflection part and the second reflection part is coated with a metal coating, the first reflection part is a paraboloid outwards diffusing along inside of the glass shell from the top to bottom, the second reflection part is a paraboloid inwards drawing together along the outside of the glass shell, the height of the first reflection part is 8.5-11cm, the thickness of a circular ring formed by a vertical projection of the first reflection part on a horizontal plane is 3-5cm, the height of the second reflection part is 0.5-1.2cm, and the thickness of a circular ring formed by a vertical projection of the second reflection part on the horizontal plane is 0.2-0.8cm. According to the high-light effect halogen lamp, the heights and the widths of the first reflection part and the second reflection part are reasonably set, so that light can be well reflected, thus high lighting effect is obtained.

Description

High light efficiency Halogen lamp LED

Technical field

The utility model relates to a kind of Halogen lamp LED, the good Halogen lamp LED of particularly a kind of intensity of illumination.

Background technology

Existing is the common Halogen lamp LED of luminous element with the tungsten filament, and luminous flux is not high, and generally all only has 1000 hours useful life, is the product that a kind of energy consumption is high, light efficiency is low, comprises many countries of European Union at present, has prohibited import and has sold this series products.

So someone has made improvement, on the glass bulb inwall, scribble metallic reflector, make the light beam that has obtained broad; Its light efficiency and brightness have been improved to a certain extent; But find in using that it still has deficiency, such as when being applied to the higher place of required intensity of illumination; Still not competent, tracing it to its cause, it is reasonable inadequately mainly to be that the shape of glass bulb is provided with.

Summary of the invention

The utility model has overcome the deficiency that exists in the above-mentioned prior art, provides a kind of and not only can improve light efficiency, can also significantly improve intensity of illumination, and keeps the good inhomogeneity Halogen lamp LED of beam spread.

The technical scheme of the utility model is achieved in that

A kind of high light efficiency Halogen lamp LED comprises lamp holder, glass bulb; Stem stem, the seal wire of drawing in the filament, the two ends of filament and stem stem links to each other; In glass bulb, be filled with halogen gas; Described glass bulb is to be merged mutually by neck shape head, first reflecting part, second reflecting part and printing opacity bottom, and middle part to the first reflecting part of neck shape head and the inner surface of second reflecting part scribble metal coating, and first reflecting part is to the parabola of outside diffusion along glass bulb inside from top to bottom; And the axis of first reflecting part and the dead in line of glass bulb; Second reflecting part is the parabola drawn close to inside along the glass bulb outside from top to bottom, and the height of described first reflecting part is 8.5～11cm, and the thickness of the annulus that the upright projection of first reflecting part on horizontal plane forms is 3～5cm; The height of second reflecting part is 0.5～1.2cm, and the thickness of the annulus that the upright projection of second reflecting part on horizontal plane forms is 0.2～0.8cm.

As preferably; The height of first reflecting part is 9cm; The thickness of the annulus that the upright projection of first reflecting part on horizontal plane forms is 3cm, and the height of second reflecting part is 0.6cm, and the thickness of the annulus that the upright projection of second reflecting part on horizontal plane forms is 0.3cm.

As preferably, along on the glass bulb axis direction, filament is in the medium position of second reflecting part.

As preferably, described metal coating is an aluminized coating.

Adopted the beneficial effect of the utility model of technique scheme to be:

The Halogen lamp LED of the utility model has first reflecting part and two reflectings surface of second reflecting part; The light that first reflecting part can directly be launched Halogen lamp LED reflects away; The light that second reflecting part is launched Halogen lamp LED reflexes on first reflecting part and reflects away via first reflecting part; The light beam that the printing opacity bottom is penetrated is through stack, thereby intensity of illumination improves greatly; The most important thing is that the utility model has carried out reasonable setting to height, the width of first reflecting part, second reflecting part, makes light better to reflect, thereby has obtained high light efficiency.

Embodiment

The embodiment of the utility model is following:

Embodiment: a kind of high light efficiency Halogen lamp LED, as shown in Figure 1, comprise lamp holder 8; Glass bulb 1, stem stem 9, filament 10; The seal wire 11 of drawing in the two ends of filament 10 and the stem stem 9 links to each other, and in glass bulb 1, is filled with halogen gas, and described glass bulb 1 is to be merged mutually by neck shape head 2, first reflecting part 3, second reflecting part 4 and printing opacity bottom 5; Middle part to the first reflecting part 3 of neck shape head 2 and the inner surface of second reflecting part 4 scribble layer of metal coating 6; Described metal coating 6 is an aluminized coating, and along on glass bulb 1 axis direction, filament 10 is in the medium position of second reflecting part 4.

First reflecting part 3 is the parabolas that spread to the outside along glass bulb 1 inside from top to bottom, and the axis of first reflecting part 3 overlaps with the axis 7 of glass bulb 1; From top to bottom second reflecting part 4 be one along glass bulb 1 outside to inside draw close parabola; The height of first reflecting part is 9cm; The thickness of the annulus that the upright projection of first reflecting part on horizontal plane forms is 3cm; The height of second reflecting part is 0.6cm, and the thickness of the annulus that the upright projection of second reflecting part on horizontal plane forms is 0.3cm.
