Embodiment Construction

[0022] The present invention is described in further detail below in conjunction with embodiment:

[0023] figure 1 is a front view of the light source substrate of the present invention, figure 2 A-A sectional view of the light source substrate. Depend on figure 1 combine figure 2 It can be seen that the substrate 1 of the present invention is a flat-bottomed groove, preferably a V-shaped groove with a flat bottom or an arc-shaped groove with a flat bottom, so as to have a good light-gathering effect. The base plate 1 can be made of metal materials such as aluminum, copper or magnesium (or aluminum, copper or magnesium alloy materials), and of course other good conductors of heat, such as new non-metallic materials, are also available.

[0024] image 3 yes figure 2 The partial enlarged view of B is shown. Depend on image 3 It can be further seen that a thermally conductive insulating layer 2 is provided close to the surface of the substrate 1, and a circuit and s...

Abstract

The invention discloses a groove-shaped LED light source substrate as well as a production method thereof and a fluorescent lamp applying same. The substrate is of a groove shape, the surface of a light source substrate is provided with a heat conduction insulation layer, circuits and welding spots are laid on the heat conduction insulation layer, a light reflecting layer covers on other places except the welding spots on the heat conduction insulation layer, the groove bottom of the substrate is provided with a plurality of transparent calathiform bowl-type bodies, each calathiform bowl-type body is internally fixed with a luminescent wafer, and two educing leads on each luminescent wafer are respectively welded on corresponding welding spots. The LED substrate has the advantages of high light throughput efficiency, energy saving, environment protection, no toxic materials, high reliability and the like and has the power consumption lower than above 40 percent of a traditional fluorescent lamp and extremely compact structure because the LED substrate and a light source driver are jointly placed in lamp tubes (T5. T4, T8, T10 and the like) with common dimensions, thus the lamp tubes prepared in such a way can be directly installed on the support of the traditional fluorescent lamp, thereby greatly saving the cost for users.

Description

technical field [0001] The invention relates to an LED light source substrate, in particular to a slot-type LED light source substrate, a production method thereof, and a fluorescent lamp applied thereto. Background technique [0002] Due to the increasingly prominent problems of global environmental pollution and energy shortage, people began to consider various aspects of energy conservation and environmental protection. Traditional lighting fixtures such as incandescent lamps or fluorescent lamps are gradually recognized by the world due to their high energy consumption and the presence of liquid and gas substances that pollute the environment. [0003] At present, with the rapid development of LED technology, the theoretical light effect of LED (260 lumens per watt) has far exceeded that of traditional incandescent lamps, and even surpassed some fluorescent lamps. Since the Beijing Olympic Games in 2008, LED has been widely used in various display fields, such as indoor...
