Abstract

The utility model discloses a halogen lamp, which comprises a lamp cap, a glass shell, a core column and a filament, wherein both ends of the filament are connected with a guide wire led out of the core column, the glass shell is filled with halogen gas, the glass shell consists of a neck-shaped head, a first reflecting part, a second reflecting part and a light permeable bottom, a metal coating is coated from the middle part of the neck-shaped head to the inner surfaces of the first reflecting part and the second reflecting part, the first reflecting part from top to bottom is a paraboloid diffusing outwards along the inner part of the glass shell, the axis of the first reflecting part is superposed with the axis of the glass shell, and the second reflecting part from top to bottom is a paraboloid drawn together inwards along the outer part of the glass shell. The halogen lamp is provided with the first reflecting part and the second reflecting part, the first reflecting part can directly reflect out light emitted by the halogen lamp, the second reflecting part reflects the light emitted by the halogen lamp onto the first reflecting part, then the light is reflected out via the first reflecting part, the light beams emitted by the light permeable bottom are superposed, so the illumination intensity is greatly increased.

Description

A kind of Halogen lamp LED

Technical field

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

Background technology

Existing is the common Halogen lamp LED of luminous element with the tungsten filament, and its colour temperature can only reach 2500K, and luminous flux is not high, and generally all only have 1000 hours useful life, be a kind of energy consumption height, product that light efficiency is low, comprise at present and prohibited many countries of European Union import and 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, improved its light efficiency and brightness to a certain extent, but found in using that it still has deficiency, such as when being applied to the higher place of required intensity of illumination, still not competent.

Summary of the invention

The utility model has overcome above-mentioned the deficiencies in the 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 solution of the utility model is achieved in that

A kind of Halogen lamp LED, comprise lamp holder, glass bulb, stem stem, filament, the seal wire of drawing in the two ends of filament and the stem stem links to each other, in glass bulb, be filled with halogen gas, described glass bulb is by neck shape head, first reflecting part, second reflecting part and printing opacity bottom merge mutually, middle part to the first reflecting part of neck shape head and the inner surface of second reflecting part scribble the layer of metal coating, first reflecting part is the parabola that spreads to the outside along glass bulb inside from top to bottom, and the dead in line of the axis of first reflecting part and glass bulb, and second reflecting part is a parabola of drawing close to inside along the glass bulb outside from top to bottom.

As preferably, described second reflecting part is an arc surface.

In order to play uniform reflecting effect, as preferably, the circle centre position of described arc surface is on the axis of glass bulb.

As preferably, described metal coating is an aluminized coating.

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

Halogen lamp LED of the present 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.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Embodiment of the present utility model is as follows:

Embodiment: a kind of Halogen lamp LED, comprise lamp holder 8, glass bulb 1, stem stem 9, the seal wire 11 of drawing in the filament 10, the two ends of filament 10 and stem stem 9 links to each other, in glass bulb 1, be filled with halogen gas, 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, and 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, and described metal coating 6 is an aluminized coating.

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, second reflecting part 4 is an arc surface, and the circle centre position of arc surface is on the axis 7 of glass bulb 1.
