Embodiment Construction

[0015] Typical embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] figure 1 and figure 2 As shown, a luminous tube, the luminous tube includes a glass shell 1, a filament 2 in the shell, a phosphor coating, an inert gas 3, a tube head 4 and a foot 5; it is characterized in that: the shell has a controllable The cathode controlled by silicon is used to trigger the anode 6 of the control. The cathode is any one end of the double filament in the energy-saving lamp, or the lamp pins of the two filaments are connected together. The anode is a conductive material coated outside the shell. The metal film, or the metal foil is pasted on the shell by conductive stickers, and the lamp pins are led out by the metal hoop.

[0017] image 3 The same as the shape of the luminous tube, it is a straight tube-shaped luminous tube with an external anode.

[0018] Figure 4 It is a straight tube-shaped light-emittin...

Abstract

The invention provides a light-emitting tube is formed by assembling a red light-emitting tube, a green light-emitting tube, a blue light-emitting tube, tube heads and covers, wherein the covers play soft light roles and are arranged on the tube heads. The light-emitting tube has the advantages of high brightness, luminosity factor and capabilities of realizing the color regulation of light emission of a screen midpoint by respectively regulating brightness, emitting consistent and gentle colors without seeing a lamp filament and a local intense light point, and the like, and can be widely used for the aspects of advertisements, prompts, information dissemination, and the like of a station, a square, a port, a large departure hall, a large waiting hall, a stadium, a street, and the like.

Description

technical field [0001] The invention belongs to the light source technology, and mainly relates to a light-emitting element. Background technique [0002] At present, in the existing large-screen display technology, LED light-emitting diodes are used for the light-emitting elements in the point light source matrix. As we all know, due to the characteristics of LED components, the afterglow tail is too long, the luminous efficiency is very low, and the luminous brightness cannot be adjusted. When the specified rated voltage is 2-2.5V, avalanche conduction is often generated, and it is not lit when it is lower than this voltage, and the brightness is not increased when it is higher than this voltage. Because there is no change in brightness level, the color is monotonous, etc., and it is used as a large-screen display. Generally only red, green, orange three colors. For large screens used in stations, squares, ports, large waiting rooms, car halls, stadiums, and streets for ...
