This connected mode between light source and the circuit board of low pressure lamp strip installation is electric connection, the light source equidistance sets up the upper surface at the lamp strip, the power cord is provided with two altogether, and its bilateral symmetry installs the front end at the lamp strip, current lamp strip is direct through the circuit board circular telegram, the drawback is the circuit board circular telegram, lamp strip length exceeds 5m, for example 10m, 20m, can influence current-voltage's stability, reduce the light source effect, the tail end probably is not bright, two power cords have been increased in the lamp strip body, current-voltage's unstability in the past has been improved, also can guarantee the stability of lamp source effect under the condition of lamp strip overlength, the lamp tail can light as usual, the reinforcing light source effect.
Description
Technical Field
The utility model relates to the field of lighting technology, specifically a low pressure lamp strip.
Background
The lamp strip is another name of the lamp strip and is also named due to the shape of the lamp strip. The Chinese character is obtained by adding relevant materials to the Chinese character. The lamp strips are characterized by being soft, capable of being curled like electric wires, capable of being cut and connected in a extending mode, and capable of completely wrapping bulbs and circuits in flexible plastics, and are good in insulation and waterproof performance, safe to use, strong in weather resistance, not prone to cracking and long in service life.
The lamp strip that has the market commonly used is that copper foil circular telegram on directly passing through the circuit board exists certain drawback: because the copper foil thickness on the circuit board is limited, and there is the power consumption loss of various electronic components on the circuit board, therefore the circuit board is voltage drop (commonly known as the pressure drop) gradually more to the back, and voltage drop, then the electric current of supplying with the light source also can reduce and lead to the luminance to reduce thereupon, and the luminance contrast difference between the head and the tail both ends of lamp strip length within 5 meters generally can also be accepted by the naked eye, exceeds after 5 meters, the pressure drop is bigger and bigger, and the luminance of light source will be lower and more, leads to the serious nonconformity of luminance at the back with the anterior. Therefore, great trouble is brought to the installation of the light bars, the light bars need to be divided into a plurality of light bars with the length of more than 5 meters, and the light bars need to be connected in parallel from a main line to the rear of a power supply. In view of the above-mentioned drawbacks of the prior art, there is a need for further improvement to make it more practical to meet the actual use situation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a low pressure lamp strip to it is direct through the circuit board circular telegram to propose current lamp strip in solving above-mentioned background art, and the drawback is the circuit board circular telegram, and lamp strip length exceeds 5m, for example 10m, 20m, can influence current voltage's stability, reduces the light source effect, and the tail end probably is not bright problem.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a low pressure lamp strip, includes lamp strip, circuit board, light source and power cord, the top of lamp strip is provided with the circuit board, and the top of circuit board is fixed with the light source, the power cord is installed to the front end of lamp strip.
Preferably, the light source is electrically connected with the circuit board.
Preferably, the light sources are arranged on the upper surface of the light bar at equal intervals.
Preferably, the power lines are arranged in two, and are symmetrically arranged at the front end of the lamp strip.
Compared with the prior art, the beneficial effects of the utility model are that: this low pressure lamp strip has planted two power mainlines in the lamp strip body, crosses to change on the original main circuit board from the independent mainline to crossing, because the electric wire is thick enough and the line loss is less than the circuit board greatly, therefore the voltage drop can slow down very much. The lamp strip manufactured by the improved scheme can realize the use length of a single lamp strip with the length of 15-30 meters (within 5 meters in the conventional market), greatly improves the installation convenience, and has small front and back brightness difference and good effect.

FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a front view of the present invention.
In the figure: 1. lamp strip, 2, circuit board, 3, light source, 4, power cord.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a low pressure lamp strip, includes lamp strip 1, circuit board 2, light source 3 and power cord 4, the top of lamp strip 1 is provided with circuit board 2, and circuit board 2's top is fixed with light source 3, the connected mode between light source 3 and the circuit board 2 is electric connection, the 3 equidistance of light source sets up the upper surface at lamp strip 1, power cord 4 is installed to the front end of lamp strip 1, power cord 4 is provided with two altogether, and its bilateral symmetry installs the front end at lamp strip 1.
The working principle is as follows: when using this low pressure lamp strip, at first with 1 switch on power of lamp strip, 1 internal two power cords 4 that have increased of lamp strip to improve the current-voltage's in the past unstability, also can guarantee the stability of lamp source effect under the condition of 1 overlength of lamp strip, reinforcing light source effect, this is the device's whole course.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
