Abstract

The utility model relates to an LED energy-saving ceiling lamp, comprising a plurality of blocks of LED area light source, which is uniformly distributed on the metal base disk of the ceiling lamp, the plurality of blocks of the LED area light source are connected in series in sequence, and are powered by the constant current source transformed from AC to DC; the LED area light source is fixed on the metal base disk by the insulating and heat conducting glue; the plurality of blocks of area light source are divided into two or more groups of parallel units, each unit of the LED area light source is connected in series, and powered by the constant current source transformed from the AC to DC. The LED energy-saving ceiling lamp of the utility model has the advantages of uniform head radiation, no need of addition heat radiators, energy-saving, environmental-protection, long service life, high chromogenic index, non electromagnetic interference, no stroboflash, no dizzy light and no ghost. Compared with the fluorescent energy-saving ceiling lamp with same illumination intensity, the LED energy-saving ceiling lamp saves about half of electricity.

Description

The energy-saving lamp affixed to the ceiling of LED

Technical field

The utility model relates to the energy-saving lamp affixed to the ceiling of a kind of LED, particularly relates to the lamp affixed to the ceiling that a kind of LED of utilization area source is made.

Background technology

At present, because science and technology development and progress, setting up conservation-minded society has become human common recognition.Along with the low-carbon (LC) growth in the living standard, the environmental protection and energy saving product has obtained use more and more widely more, wherein electricity-saving lamp is wherein general a kind of product, and existing electricity-saving lamp generally comprises in lamp socket and fluorescent tube, the lamp socket and includes electronic devices and components, and fluorescent tube links to each other with electronic devices and components.It is low that electricity-saving lamp has solved incandescent lamp luminous efficiency commonly used.The problem that caloric value is big and the life-span is short, so its popularization is very rapid, has obtained popularizing widely.

But existing electricity-saving lamp, be subjected to the restriction of lamp tube shapes, and need be fixed on the lamp socket, make the appearance and size of light fixture also correspondingly be restricted, and owing to directly adopt AC-powered, be easy to generate electromagnetic interference, add and use Inductive ballast or electric ballast, can cause stroboscopic and photoresonance, can people's vision system be damaged.

The utility model content

At above-mentioned the deficiencies in the prior art, the utility model proposes a kind of New LED energy-saving ceiling lamp.

The technical solution of the utility model is like this:

A kind of LED energy-saving ceiling lamp comprises the area source by polylith LED, and it is evenly distributed on the metal chassis of lamp affixed to the ceiling, and described polylith LED area source connects successively by series connection, is become the constant-current supply power supply of direct current by exchange conversion.

LED energy-saving ceiling lamp described in the utility model, described polylith LED area source is fixed on the metal chassis with the insulating heat-conductive glue bond.

LED energy-saving ceiling lamp described in the utility model, described polylith LED area source are divided into two groups or more also joint group, and every group LED area source is connected, and are become the constant-current supply power supply of direct current by exchange conversion.

The utlity model has heat radiation evenly, need not to add again radiator, energy-conserving and environment-protective, extra long life, colour rendering index height, no electromagnetic interference, no stroboscopic, free from glare, advantages such as no ghost image.Its energy-saving effect is compared power saving 50% with the fluorescence energy-saving ceiling lamp of same illumination.Life-span reaches 50000 hours, is tens times of common fluorescence energy-saving ceiling lamp.

The utility model does not have electromagnetic interference, owing to be to power to area source after alternating current becomes direct current, so there is not electromagnetic interference.

The utility model does not have stroboscopic, compares with the fluorescence energy-saving ceiling lamp, and the stroboscopic that no Inductive ballast or electric ballast cause can not form photoresonance, can people's vision system not damaged.Because adopt area source, light is sent by a uniform plane, rather than is sent by point, colour rendering index is higher than 80, helps reducing the degree of fatigue of human eye, can not stimulate human eye, and is very favourable to vision protection.Be unlikely to make the people to produce moods such as mood is sick of, irritable uneasiness.

Fig. 2 is the distribution schematic diagram of modular surface light source of the present utility model at ceiling lighting.

Fig. 3 is a sectional axonometric drawing of the present utility model.

The specific embodiment

Among Fig. 1-Fig. 3,1 expression lampshade; 2 expression metal chassis; 3 presentation surface light source modules; 4 represent power module, and 5 is thermal conductive insulation glue; 6 is dogging.

As shown in Figure 1, circuit theory of the present utility model comprises the power module 4 of an alternating current-direct current rectification, and in order to stable direct current constant current power supply to be provided, the example of the 48V that Fig. 1 provides can be designed to different voltage ranges such as 36V or 24V as required.

Illuminator among Fig. 1 is a LED modular surface light source 3, can be designed to polylith as required, for example, and the 4-32 piece.Fig. 1 has only provided the signal of LED modular surface light source 3 polyphones, it should be appreciated by those skilled in the art that according to the situation of direct current constant current power supply, can adopt serial or parallel connection, multiple connected modes such as the parallel connection of perhaps dividing into groups.

The LED modular surface light source is to be arranged by matrix form by the low power LED core to be evenly distributed on the aluminium base (copper base), after encapsulation, becomes the LED modular surface light source.For example,, be evenly distributed on the aluminium base (copper base), after encapsulation, can become LED area source 1W module by the matrix form arrangement with 16 in 0.06W low power LED core.Therefore, can manufacture various daily light fixtures such as lamp affixed to the ceiling, desk lamp, cast fluorescent lamp, wall lamp, bulb lamp, garden lamp.

Fig. 2 is the distribution schematic diagram of modular surface light source of the present utility model at ceiling lighting.In conjunction with Fig. 1, what provide among Fig. 2 is that 8 LED modular surface light sources 3 are arranged on the lamp affixed to the ceiling metal chassis 2 equably, presents the circumference formula along the edge and arranges.Certainly, at the circuit side connector face, these 8 LED modular surface light sources also can divide 2 groups, two groups of parallel connections then, and this depends on the coupling with power module 4.

Among Fig. 2, also comprise a pair of fixture 6 that is used to pin lampshade 1.Described fixture can be the dogging near the L type.Among Fig. 3, the structure of dogging is more clear.Dogging is made up of two mouldings, one is installed in the metal chassis inboard, pin the lamp affixed to the ceiling lampshade, another piece is installed in the metal chassis outside, manual trigger piece, two fasten as one by screw, when trigger piece rotates to an angle, dogging also rotates to an angle synchronously, reaches the purpose of the locking lampshade or the lampshade of loosening.

Fig. 3 has provided three-dimensional cutaway view of the present utility model, is used for illustrating the layout and the correlation of inner device.Be used for fixing modular surface light source 3 and power module 4 on the metal chassis 2, adopt insulating heat-conductive glue 5 to fix these assemblies, simple and reliable process, radiating efficiency height.
