Embodiment Construction

[0051] see figure 2 and image 3 As shown, a high-pressure gas discharge lamp with an auxiliary reflection device provided by a preferred embodiment of the present invention can reflect the ineffective light generated by the discharge lamp tube, change its projection path, and form effective light to improve Lighting effects of high pressure gas discharge lamps.

[0052] The high-pressure gas discharge lamp with an auxiliary reflector of the present invention includes: a reflector 10 , a front lamp cover glass 20 , a discharge lamp 30 , an auxiliary reflector 40 and a cooling device 50 .

[0053] The inner surface of the reflector 10 forms a main reflective surface 11, and the main reflective surface 11 is usually in the shape of a paraboloid or an ellipse. On the outer surface of the reflector 10 , an outwardly protruding neck 12 (Neck) is formed corresponding to the position of the axis, and the central axis of the neck 12 has a through hole 13 . The headlight cover glas...

Abstract

The invention relates to a high-pressure gas discharging lamp with auxiliary reflector, which comprises a reflective cover, a discharging tube, an auxiliary reflective mirror and a cooling device, wherein the discharging tube is inserted into the neck of reflective cover, while its discharge field is at the inner side of reflective cover; the auxiliary reflective mirror has one auxiliary reflective surface and one through hole, while the auxiliary reflective mirror is sheathed on the discharge tube; the auxiliary reflective surface is toward to the discharge field and the inner side of reflective cover; the auxiliary reflective surface reflects to the ineffective light of discharge field to the reflective cover, to form useful effective light, to improve the density of high-pressure gas discharge lamp; and the cooling device can generate one cooling airflow, to cool the discharge tube and the auxiliary reflective mirror, to keep their temperature under the up limit of working temperature, to prolong the service life.

Description

technical field [0001] The invention relates to a high-pressure gas discharge lamp, in particular to an auxiliary reflection device for a high-pressure gas discharge lamp, which is used to strengthen the reflection effect of the reflector to increase the effective light intensity. Background technique [0002] Please refer to figure 1 As shown, the high-pressure gas discharge lamp can be roughly divided into three parts: reflector 1 , discharge lamp tube 2 and front lamp cover glass 3 . The inner side of the reflector 1 forms an elliptical or parabolic reflective surface 1a, and the discharge lamp 2 is fixed on the axis of the reflector, and the spherical shell-shaped discharge area 2a is located at the focus of the reflective surface 1a. The headlight cover glass 3 is placed in front of the reflector 1 to filter out invisible spectrums such as infrared light and ultraviolet light, and only allow visible light to pass through. [0003] The discharge lamp 2 emits light from...
