A Produce Method Of High Power SENKEN Warning Lightbar With Siren And Speaker
A produce method of high power SENKEN warning lightbar with siren and speaker
Background technology:
At present, warning lights can be seen in many places of our life. Long row warning lights are mainly used in vehicles. Sometimes warning lights need to be used in high temperature environment, and high-power LED lights and other supporting electronic components will also generate heat, especially some high-power warning lights. At the same time, the electronic components of the lights are in a relatively closed shell, so the heat dissipation effect is poor, Because of overheating, the circuit will be in the protection function and stop working, or it is easy to cause electronic components damage, aging, resulting in the warning light can not work.
Technical implementation elements:
The technical problem to be solved by the invention is to provide a high-power long row warning lamp which can not only maintain a certain luminous intensity, but also prevent the electronic components from overheating, and can save energy.
In order to solve the above technical problems, the invention adopts the following technical solutions: a high-power long row warning lamp, including a bottom shell, a lampshade and a LED lamp, the lampshade is arranged on the bottom shell, the LED lamp is arranged under the lampshade, and the LED lamp comprises a LED lamp bead, an aluminum substrate, an electronic component and a lamp bowl; The lamp bowl is trumpet shaped, including a bottom face, a mouth, a top face, a lower face and two sides of faces. A top opening is arranged at the position of the top face close to the bottom face. The lamp bowl is more than one pair and is adjacent to the bottom face, and the mouth is arranged outward. A reflective layer is coated on the inner surface of the lamp bowl, an aluminum substrate is arranged on the upper side between the two lamp bowls, and a fixed foot is arranged outside the lamp bowl; The LED lamp t bead and the electronic component are arranged on the aluminum substrate, and the LED lamp bead is located in the top opening.
As a preferred scheme of the invention, the two sides of the face are curved inward near the bottom face, the bottom faces of the two adjacent lamp bowls are connected or designed as a whole, the outer side between the bottom faces of the two adjacent lamp bowls forms a secondary heat dissipation area, and the LED lamp beads on the aluminum substrate are divided into a-zone lamp beads, B-ZONE lamp beads, C-zone element and d-zone element, with a-zone lamp beads and B-ZONE lamp beads symmetrically distributed and C-zone lamp beads symmetrically distributed The element and the d-zone element are symmetrically distributed, the C-zone element and the d-zone element are located in the auxiliary heat dissipation area, the lamp beads in the a-zone and the lamp beads in the B-ZONE are matched and correspondingly located in the top opening, and the electronic elements on the aluminum substrate are arranged in the C-zone element and / or the d-zone element.
As another preferred scheme of the invention, the lower face is inclined in the direction from the mouth to the bottom face, and the intersection of the lower face and the bottom face is an arc transition, the intersection of the two sides of the face and the bottom face is an arc transition, and the top face is a plane.
As another preferred scheme of the invention, the two adjacent bottom faces are located in the auxiliary heat dissipation area and are provided with a fixed seat, the aluminum substrate is fixed on the fixed seat by screws, both sides of the lamp bowl are provided with fixed feet, and the fixed feet are fixed on the bottom shell.
As a further preferred scheme of the invention, the pair of lamp bowls are multiple and are arranged side by side under the lamp shade, the outside of the lamp bowl is provided with a reflective layer, the front and rear sides of the shell are located under the lamp bowl, and four through holes are arranged, and a plurality of aluminum substrates are connected
Connect by wire. The invention adopting the above technical scheme has the following advantages: the lamp bowl is trumpet shaped, including the bottom face, mouth, top face, lower face and both sides face, the top opening is arranged at the position of the top face close to the bottom face, the inner surface of the lamp bowl is coated with a reflective layer, and the LED lamp bead is located in the top opening, The lamp bowl is above – pair, and the auxiliary bottom face is adjacent to each other, and the mouth is outward. Such a setting can reduce the number of LED lamp beads, reduce the power consumption, and reduce the heat generated by electronic components while maintaining the increase of brightness at least without weakening;
