Abstract

A cold cathode photo-source comprises a lens hood, a lamp, an inverter, a reflecting cover, and a lamp-holder. The cold cathode photo-source is characterized in that the inverter is designed with two relaying inserting needles and lamp is winded into cone shaped.

Description

A kind of cold cathode luminous source

Technical field

The utility model relates to a kind of cold cathode luminous source, and finger can substitute the cold cathode luminous source in the various floodlights of being installed in of 111 millimeters aluminium reflectors of Φ Halogen lamp LED especially.

Background technology

111 millimeters aluminium reflectors of Φ Halogen lamp LED is as the light source of floodlight, be widely used in the commercial lighting in hotel, market, its power is generally at 50W to 100W, service life is generally at 2000h, beam angle is spent to 24 degree 8, the problem that its highly energy-consuming and caloric value are high is well-known, but suffers from the special tectonic of 111 millimeters aluminium reflectors of Φ light fixture and good beam angle, makes existing energy-conserving light source to substitute.

Summary of the invention

The purpose of this utility model is to release a kind of new cold cathode luminous source, and its structure is fit to existing 111 millimeters aluminium reflectors of Φ light fixture fully, has good beam angle, and 111 millimeters aluminium reflectors of Φ halogen light source is substituted by energy-conserving light source becomes possibility.

The technical solution of the utility model is as follows:

A kind of cold cathode luminous source comprises light shield, fluorescent tube, inverter, reflector, lamp holder, and inverter is positioned at the fluorescent tube top, design has two to connect the electric mortiser pin on the inverter, fluorescent tube turns to taper, and the top of taper fluorescent tube is towards the bottom of reflector, and design has louvre around the light shield.

Reflector of the present utility model and lamp holder are exactly the parts of ALR111 type Halogen lamp LED; the following design of inverter connects the electric mortiser pin and can peg graft or weld with lamp holder and cooperate; the top design of inverter has light shield; inverter is protected, prevent to get an electric shock, the function of anti-dazzle is also arranged; the fluorescent tube coiling is taper; match with reflector, can converge the light that fluorescent tube sends and reflect away, play optically focused and energy-conservation effect.

The beneficial effects of the utility model are: can be replaced by cold cathode luminous source to the light source in 111 millimeters aluminium reflectors of various Φ halogenic lamps and lanterns easily, more new lamp just can reach energy-conservation purpose.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Shown in Fig. 5,6, contact pin (6) is vertically fixed on inverter (2) middle part, and the spacing of two contact pins (6) is 5.3-6.3mm, then fluorescent tube (3) is enclosed within on the contact pin (6), lamp lead (7) is welded on the inverter (2), and at this moment the termination of contact pin (6) passes from fluorescent tube (3) top; Then, lamp holder (5) is buckled in reflector (4) goes up fixingly, contact pin (6) is vertically pegged graft again or be welded on the lamp holder (5), at last light shield (1) is buckled on the inverter (2), the corresponding draw-in groove that inserts reflector (4) both sides in the two ends of light shield (1) is fixed.

Claims
