Embodiment Construction

[0050] Concrete structure of the present invention is by following embodiment and its accompanying Figure 4-20 give.

[0051] Reflector: extruded from light alloy or synthetic material 6, with card guide slot 10 for inserting and replacing the vacuum coating reflective sheet 8 inside. The base of the reflective sheet is PET synthetic material with a thickness of 70μ-100μ. 5 mm to 20 mm from the center line or take the 1 / 2 size of the glass bulb diameter (φ) of the matching fluorescent tube 13 and the width of the H-type fluorescent tube 17.

[0052] The distance from the bottom reference line is 4mm~50mm downward, and the symmetrical point 11 is set as the center of the circle, and the spherical concave surface 7 on the left and right upper sides is given. Figure 5-6 , 13~14;

[0053] The distance from the bottom reference line is 4mm to 50mm downward, and the symmetrical point 11 is set to give the spherical concave surface 9 on the left and right sides. The size range is R...

Abstract

The present invention is variable angle reflecting straight-tube fluorescent lamp used especially in indoor lighting. The reflector is constituted by extruded special aluminium alloy or other alloy shape and embedded replaceable vacuum filmed reflecting sheet. The reflecting composite surface can reflect 2 / 3 upwards radiating light to the lighted area. The lamp can change its lighting angle in 180 deg range for directional lighting by means of its angle changing mechanism. Compared with available technology, the present invention has 3-4 times higher lighting illuminance.

Description

technical field [0001] The invention relates to a variable-angle reflective straight-tube fluorescent lamp, which is suitable for indoor lighting. Background technique [0002] Commonly used panel fluorescent lamps figure 1 and Chinese patent application 87300511.2 figure 2 Generally, it is mainly composed of a bracket plate, a lampshade, and a fluorescent tube, and fails to involve the problem of utilizing the upward radiant light energy of the fluorescent tube and the variable-angle expansion of the lamp to effectively utilize the light. Therefore, the efficiency of lamps, the utilization coefficient of lamp light and the brightness coefficient are relatively low. After actual research and testing of the 360° radiant light energy of the light pipe, only about 120° downward, that is, 1 / 3 of the light illuminates the lighting area, and the remaining upward about 240°, or 2 / 3, of the light energy is not utilized and is lost in the lampshade in or on the ceiling.
