Abstract

The utility model relates to a white-light LED ceiling light, which comprises a chassis, heat sinks and a glass cover, wherein the two heat sinks are installed on the two sides of the inner portion of the chassis, and the organic glass cover is fixed on the chassis from the lower portion. The utility model is characterized in that a voltage-converting device is installed on the center position of the inner portion of the chassis, the positive pole and the negative pole of the output end of the voltage-converting are respectively connected with the positive pole and the negative pole of a PCB printing circuit board, the PCB printing circuit board is fixed on the bottom portion of the chassis, and a white-light LED is welded on a through-hole of the PCB printing circuit board. The utility model has the advantages of even light intensity and extensive radiating surface after adopting surface light source lighting, and the white-light LED has the characteristics of energy-saving, long service life, adjustable color temperature, strong brightness and green and environmental-friendly and the like. And the white-light LED is not easy to be broken, and has excellent shock proof performance, which fulfills the national technical requests for ceiling light. The utility model also overcomes the several weaknesses of a traditional ceiling light for a ship, and is improved on property, which is suitable to be used on small-sized ships.

Description

The white light LEDs ceiling light

Technical field

The utility model relates to a kind of light fixture, particularly relates to a kind of boats and ships white light LEDs ceiling light.

Background technology

Traditional boats and ships are a lot of with the ceiling light kind, incandescent lamp, fluorescent lamp etc. are arranged, its basic structure has lamp socket, ballast, fluorescent tube, protective device etc., because its cost is low, obtained using widely, but also there are many shortcomings in this traditional boats and ships with ceiling light: 1, the conversion efficiency from the electric energy to luminous energy is low, power consumption is big, especially electric energy is had in the boats and ships light fixture of certain limitation, electric energy seems and is even more important that it is crucial rationally utilizing electric energy; 2, the life-span is short; 3, poor seismic behavior, broken easily, so all be added with external protector, as safety glass, stainless steel protection spare etc. have increased manufacturing cost; 4, toxic gas is contained in inside, contains mercuryvapour as the fluorescence ceiling light, in case broken can damaging human body.

Summary of the invention

The purpose of this utility model provides a kind of boats and ships white light LEDs ceiling light, and it can improve the energy conversion efficiency of ceiling light, saves electric energy.

A kind of white light LEDs ceiling light, base, heat abstractor and cloche are arranged, two heat abstractors are contained in the both sides of base inside, plexiglass tent is fixed on the base from the bottom, it is characterized in that having a potential device to be installed on the center of base inside, the positive pole of potential device output and negative pole connect the positive pole and the negative pole of PCB printed circuit board (PCB) respectively, and the PCB printed circuit board (PCB) is fixed in the bottom of base, and the white light LEDs pipe is welded on the PCB through-holes of printed circuit boards.

Advantage of the present utility model is to have adopted illuminated by surface light source, and light intensity is even, and radiation is wide, white light LEDs itself has energy-conservation, life-span is long, and colour temperature is adjustable, the brightness height, characteristics such as environmental protection, and white light LEDs is difficult broken, and anti-seismic performance well also meets the specification requirement of country to the boats and ships ceiling light, makes the utility model overcome the many shortcoming of traditional boats and ships with ceiling light, improvement has been arranged on the performance, be adapted at using on the spitkit.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

The utility model has base 1, potential device 2 and heat abstractor 3 are equipped with in base 1 inside, the effect of potential device 2 is that the power supply alternating current is converted to direct current, the effect of heat abstractor 3 is that the heat that base 1 inner each device produces is in time discharged base 1, PCB printed circuit board (PCB) 4 usefulness screws are fixed in the bottom of base 1, white light LEDs pipe 5 is welded on the through hole of PCB printed circuit board (PCB) 4, and plexiglass tent 6 is fixed on the base 1 from the bottom.The arrangement mode of white light LEDs pipe 5 on the described PCB printed circuit board (PCB) 4: per 5 white light LEDs pipes 5 are concatenated into one group, per 5 groups and be unified into a row, be divided into 7 rows, also be relation in parallel between row and row, positive wire on the PCB printed circuit board (PCB) 4 and negative wire are directly connected on the positive pole and negative pole of potential device 2 outputs.

When using the utility model, it is installed on the cabin top, solid and reliable, again the lead-in wire of potential device 2 inputs is connected on the gauge tap of cabin.

The circuit of potential device 2 adopts general transformation rectification circuit, the utility model parts relevant with circuit have potential device 2, PCB printed circuit board (PCB) 4 and white light LEDs pipe 5, their circuit is known, annexation between them is described, therefore just need not to have further specified circuit of the present utility model again.
