Embodiment Construction

[0010] As shown in Figure 1, a LU1000 high-pressure sodium lamp has a lamp base 1 and a lamp housing 2, and an arc tube 3 is arranged inside, and the arc tube 3 is filled with an inert gas. It is an airtight olive-shaped glass bulb, the diameter of the largest part is not more than 78mm, and the length is not more than 383mm. The lamp housing 2 is equipped with a fixing frame 5 for the arc tube 3, and the arc tube 3 is fixed on the fixing frame 5. The material used for the arc tube 3 is Translucent polycrystalline alumina porcelain tube. A certain proportion of sodium amalgam by weight is also placed in the arc tube 3, generally the ratio of sodium to mercury is 1:4. The pressure of the inert gas filled in the arc tube 3 is at least 2200Pa-3200Pa. The inner diameter of the arc tube 3 is 7-10mm, and the length is 180-250mm.

[0011] The LU1000 high-pressure sodium lamp of the present invention works at a relatively high lamp voltage of 250V, and is a green lighting product. B...

Abstract

The invented LU 1000 typed high voltage sodium lamp possesses lamp cap and lamp bulb. Inert gases are filled into electric arc tube inside lamp bulb. Electrodes are setup at two ends of the electric arc tube. Maximum diameter of lamp bulb, which is olivary glass bulb in air tightness, is not larger than 78 mm, and maximum length of lamp bulb is not longer than 383mm. rigid rack inside lamp bulb is for fixing the electric arc tube, which is made from material of semitransparent polycrystal alumina ceramic. The invented LU 1000 typed sodium lamp is operated under high voltage belonging to green illuminance product. The invented product possessing features of high light efficiency, high luminous flux and long service life can apply to illumination of large area such as square and road in super wide. Illuminating farm crops promotes growth, shortens vegetative cycle as well as compacts petals and lengthens time of opening.

Description

Technical field [0001] The invention relates to the electrical industry, in particular to a high-pressure discharge lamp. Background technique [0002] At present, the standard NG1000 high-pressure sodium lamp used in China has a lamp base and a lamp housing, and an arc tube is arranged inside. NG1000 high-pressure sodium lamp has a lamp voltage of 110±20V, an operating current of about 10.3A, and a large circuit load current. The lamp shell is a cylinder, with small space and excellent luminous flux. less efficient. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention proposes a novel LU1000 high-pressure sodium lamp. [0004] The technical solution adopted by the present invention to solve the technical problem is: a LU1000 type high-pressure sodium lamp, which has a lamp cap and a lamp housing, two electrode-combined conductive leads are arranged at both ends of the arc tube, and the vacuum airtight sealing i...
