Problems solved by technology

Its shortcoming is that each LED in the lamp body circuit can only emit one kind of monochromatic light. If the light string wants to emit multiple colors of light, it must be connected in series with multiple LEOs with different light-emitting colors, so that the volume of the lamp will inevitably increase. Larger, increases the cost, and the LEDs in the circuit have similar forward resistance, and the reverse resistance is uncertain, so the voltage distribution of the LED light string is uneven when the reverse pressure is applied, which is easy to cause the reverse direction of some LEDs in the LED light string. Breakdown due to excessive voltage

Embodiment Construction

[0015] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0016] refer to figure 2 , the main wires 11 and 12 running through the core 15 of the transparent plastic lamp body are connected with two-legged dual-color LED lamp strings 14, and the core 15 of the lamp body is covered with a layer of transparent plastic sheath 16. The main wires in the lamp body Electric wires 11 , 12 are connected with controller 17 .

[0017] refer to image 3 , 4, multiple groups of light strings 14 are connected to the two main wires 11, 12, and the light strings are connected in parallel to the main wires 11, 12 of the inner core of the lamp. Each light string can be made of A plurality of two-pin dual-primary-color LEDs 13 are connected in series, or a single two-pin dual-primary-color LED 13 is connected: the two chips 13A and 13B in the two-pin dual-primary-color LED 13 are connected in parallel, and the conduction polarity of th...

Abstract

The invention discloses a flexible tubular lamp, which comprises a controller, a transparent plastic lamp body core, a transparent plastic sheath, main wires and light strings, wherein the transparent plastic sheath is arranged on the outside of the lamp body core, the main wires run through the lamp body core, the light strings are mounted in the lamp body core, and are connected in parallel to the main wires of the lamp body core, a plurality of double-pin double-primary color LEDs (light-emitting diodes) are connected in series to form each light string, and two chips in each double-pin double-primary color LED are connected in parallel, and are opposite in conducting polarities; the conducting polarities of the chips with the same light colors in the double-pin double-primary color LEDs are opposite; a controller is utilized to control the frequencies and proportions of positive and negative pulses of current frequency to control the light-emitting frequency of each chip of each double-pin double-primary color LED, and because the frequencies and proportions of positive and negative pulses of current frequency are different, people can see bright and colorful light emitted by the flexible tubular lamp. The flexible tubular lamp can generate a color-changing effect, the structure is simple, the cost is low, the safety performance is good, and a plurality of light strings can be arranged in the limited space of the flexible tubular lamp.

Description

technical field [0001] The invention relates to lighting devices, in particular to a hose lamp. Background technique [0002] The hose lights or magic lights of the prior art are all connected in series or in parallel by miniature light bulbs. The lamp body is relatively large in size and lacks aesthetic feeling. To produce multiple colors of light for lamps or illusion lights, they must be combined with multiple monochromatic miniature bulbs, which will inevitably increase the volume of the lamp body or reduce the distance between the bulb and the bulb and the wire and the wire. When the distance between light bulbs and light bulbs and wires is reduced, they often fail to pass the electrical performance testing in European and American countries, and are prone to short-circuit danger. [0003] For example, the publication number is: 2495898, and the publication date is: Chinese patent: 01246357.4 on June 19, 2002, which discloses a "two-wire two-way LED light string (band)...
