Description

The great power LED bulkhead lamp capable

Technical field

The utility model relates to a kind of light fixture, particularly LED class lighting.

Background technology

The LED illuminating lamp is a kind of lighting that utilizes the 4th generation green light source LED to make, have that energy consumption is low, caloric value is low, long service life, stability height, response time weak point, environmentally safe, plurality of advantages such as multicolor luminous, more and more widely in fields such as various indications, demonstration, decoration, backlight, general lighting and urban landscapes.

But present being seen LED illuminating lamp needs the higher occasion of brightness to be difficult to adapt to because led chip is less, is difficult to satisfy significant deficiency such as normal illumination needs.

In order to solve the problem of brightness, a plurality of LED of serial or parallel connection increase brightness in the Lamp cup of being everlasting, though this technology has solved the problem of luminance shortage, must bring bigger caloric value owing to increase light source, have dispelled the heat into a great problem of this technical field.

Summary of the invention

The purpose of this utility model is to solve the bad problem of existing LED illuminating lamp heat radiation, and a kind of good heat dissipation, few, the job stability great power LED bulkhead lamp capable of light loss are provided.

The purpose of this utility model is achieved through the following technical solutions:

The great power LED bulkhead lamp capable, comprise lamp socket, lampshade, led light source and aluminium base, described led light source has several, be installed on the aluminium base, the parallel installation of aluminium base with lamp socket, wing shape radiator and constant voltage dc source device are equipped with in the lamp socket top, connect led light source again after the mains supply lead-in wire is received the constant voltage dc source device.

Led chip can be made the illuminator of different colors by incorporating different metallic elements.

There are led chip and face shield in led light source inside, and described led chip face shield material is glass or quartz, and face shield is that the top is to thicken gradually, and the base seal of attenuation (convex lens) gradually, profile also can be dull and stereotyped or polygon prism, face shield encapsulates with silica gel.

Described constant voltage dc source device adopts the structure of the normally used transformation of prior art, bridge rectifier, filtering, mu balanced circuit, and the dc source for the 12-36 volt of led chip output high stable guarantees the stable of light source.Wherein mu balanced circuit adopts integrated regulator LM317.

Operation principle of the present utility model is:

Compare with prior art, the utlity model has following advantage:

1, this great power LED bulkhead lamp capable, compact conformation, uniformity and uniformity that it is luminous are fine, the thermal conductivity height, light decay is little, photochromic pure, characteristics such as no ghost image can be applicable to the bigger meeting room in space, workshop, hall, factory building, storehouse, toll station, gas station, large supermarket, exhibition center, gymnasium and other places that need throw light on.

2, the fan of LED light fixture and led chip are reasonable in design, have saved the installing space of whole lamp, make the element of light fixture control more rationally, workman's assembling assembly still less.

3, wing shape aluminium alloy heat radiator can effectively spread the heat conduction, thereby reduces the temperature in the lamp body, has effectively ensured the life-span of light source and power supply.

4, light loss is few, and the light source that job stability height, led chip send can be simplified packaging technology, avoids hot spot to occur, and has reduced light decay, and it can be exported the light source areflexia equably fully, at utmost improves luminous efficiency.

5, high-power LED bulkhead lamp capable energy-saving effect is obvious, adopts high-power LED light source to be equipped with the import high-efficiency power, compares with sodium vapor lamp to can save energy more than 70%, and environmental protection is pollution-free, pollution elements such as not leaded, mercury, to environment without any pollution.

6, high-power LED bulkhead lamp capable colour rendering is good, and is more vivid to presenting of color in kind.Various photochromic optional, can satisfy the demand of varying environment, eliminated the higher or on the low side oppressive mood that causes of conventional lamp colour temperature, make vision feel more comfortable, improved work efficiency of workers.

7, the high-power LED bulkhead lamp capable adopts constant current constant voltage control, is suitable for voltage wide (AC85V-265V) and has overcome the light instability that produces electrical network, noise pollution and cause because of ballast, has avoided stimulation, the fatigue brought to eye in the work.

8, high-power LED bulkhead lamp capable decorative effect is splendid, adopts special process of surface treatment, and the optional majority kind of outward appearance color is installed simply, and convenient disassembly is applied widely
