Description

Energy-efficient compact low-pressure sodium lamp

Technical field

The utility model relates to a kind of high light efficiency energy-saving illumination low-pressure sodium lamp, specifically is a kind of energy-efficient compact low-pressure sodium lamp.

Background technology

At present SOX type low-pressure sodium lamp is generally used in the whole world, because it belongs to tube wall stable type low pressure sodium vapor discharge field, its light output density can not reach with the method that plain mode improves power and improve the light output density in finite region.Therefore just cause the big more low-pressure sodium lamp size of power just big more.For example the 180W low-pressure sodium lamp has been present maximum power, and its length has reached 1.12M, its light output density than the small light height not how little, this huge lamp body has also limited the range of application of high light efficiency low-pressure sodium lamp.

Goal of the invention

The purpose of this utility model is: in order to overcome above-mentioned deficiency, a kind of energy-efficient compact low-pressure sodium lamp is provided, and it can solve high-power low-pressure sodium lamp miniaturization technology bottleneck, effectively increases the light output density, reduce the low-pressure sodium lamp size, the low-pressure sodium lamp of green illumination is used widely.

The technical solution of the utility model is achieved in that a kind of energy-efficient compact low-pressure sodium lamp, comprise: glass lamp, U type discharge tube, lamp holder, stem stem, electrode, the U type discharge tube that two solid spaces intersect relatively is set in the described glass lamp at least, the two ends of the U type discharge tube that solid space intersects relatively are affixed by the mica support chip and the glass lamp at two ends, the described clover leaf U type discharge tube beginning connects two end electrodes respectively, and the electrode at two ends connects the lamp holder at two ends respectively by the two ends stem stem.

The U type discharge tube that described solid space relatively intersects is provided with the space mutually, and evenly is arranged on the calibration circumference with the glass lamp central axis.

Described U type discharge tube is a low pressure sodium vapor discharge pipe, and described electrode is the helical tungsten filament electrode.

The lamp holder at described two ends connects special-purpose ballast, control switch, power supply respectively.

The energy-efficient compact low-pressure sodium lamp of the utility model, its employing solid space in same glass bulb intersects installs independent U type discharge tube more than two, thereby effectively increase low sodium light output density, form three-dimensional light source, improved the illuminance of institute's illumination zone greatly, saves energy, simultaneously, reduce the low-pressure sodium lamp size greatly, the low-pressure sodium lamp that helps green illumination is used widely.

Embodiment

Embodiment 1

A kind of energy-efficient compact low-pressure sodium lamp of three-dimensional illuminated in combination, as Figure 1-3, it comprises: glass lamp 4, U type discharge tube 5, U type discharge tube 6, lamp holder 1, lamp holder 7, stem stem 2, stem stem 8, electrode 502, electrode 602, the U type discharge tube 5 of two relative right-angled intersections of solid space is set in the described glass lamp 4, U type discharge tube 6, U type discharge tube 5, the two ends of U type discharge tube 6 are affixed with glass lamp 4 by the mica support chip 3 at two ends, the openend of U type discharge tube 5 connects two end electrodes 502, the openend connection electrode 602 of U type discharge tube 6, electrode 502 connects lamp holder 7 by stem stem 8, and electrode 602 connects lamp holder 1 by stem stem 2.

The U type discharge tube 5 that described three-dimensional combination illuminant is relative right-angled intersection, U type discharge tube 6.Described U type discharge tube 5, U type discharge tube 6 are low pressure sodium vapor discharge pipe, and described electrode 502, electrode 602 are the helical tungsten filament electrode.

The lamp holder 1 at described two ends, lamp holder 7 is connected with power supply by special-purpose ballast, according to the needs that throw light on, can make two independently U type discharge tube light or light respectively wherein one simultaneously.

Concrete manufacture method:

(1) the U type discharge tube of two identical larger radius of curvature of making, crack is greater than the discharge tube diameter in the middle of it.

(2) the U type discharge tube 5 with two identical larger radius of curvature is assembled on the mica support chip 3 at two ends with the space crossed symmetry of U type discharge tube 6 relative (cross).

(3) in the middle of the mica support chip 3 stainless steel substrates is set, so that strengthen the fixing and supporting role to U type discharge tube 5 and U type discharge tube 6, at this moment U type discharge tube 5 and U type discharge tube 6 are called the combined discharge pipe.

(4) will insert and plate in the glass lamp 4 of infrared reflection film by behind the equipped respectively stem stem of the combined discharge pipe of the solid in (3), the getter sheet, two ends are the sealing-in of gas-tight property respectively, and after high vacuum, two ends are equipped with the By22d lamp holder respectively again.(being lamp holder 1 and lamp holder 7)

(5) U type discharge tube 5, U type discharge tube 6 manufacture crafts are consistent with SOX type low-pressure sodium lamp, no longer are repeated in this description.
