Description

A kind of high-power LED daylight lamp

Technical field

The utility model relates to a kind of lighting, especially a kind of light fixture that adopts LED as light source.

Background technology

Light emitting diode as internationally recognized the 4th generation green illumination light source, have energy-saving and environmental protection, long service life, distinct advantages such as shock-resistant.Along with the further raising of lumination of light emitting diode efficient, and the continuous reduction of cost, its range of application will be more wide also, progressively enter the general lighting field.

In number of patent application is " module combination type low voltage LED heliolamp " patent of 200710019355.5, with the fixing PCB wiring board in some led modules unit, the utmost point that the PCB wiring board is provided with some groups of alternate positive and negatives covers copper conductor, all negative poles cover copper conductor and all link to each other with power cathode, all positive poles cover copper conductor and all link to each other with positive source, in two adjacent positive and negative several led module unit that connect in parallel between the copper conductor that cover, all contain the high-brightness LED of some series connection in each led module unit.In this patent, adopted high-brightness white-light LED as light source, many LED is fixed on the PCB wiring board, and two single pins can't be handled the heat of whole LED really, as long-time use, as easy as rolling off a logly cause dead lamp.Single light source quantity is too much, and the uniformity of the integrated light source of whole light fixture has also been caused very big influence.

Summary of the invention

At the problems referred to above, the utility model provides a kind of high-power LED daylight lamp.

To achieve these goals, technical solution adopted in the utility model is: a kind of high-power LED daylight lamp, comprise led module, driving power, lamp holder etc., the lamp housing cross section is an arc, led module is fixed on the inner surface of lamp housing, lamp housing inside is provided with one or more cavity, correspondingly with lamp housing is provided with lens or the lampshade that the cross section is an arc;

Described led module is fixed in the groove at center of lamp housing inner surface;

Described lamp housing surfaces externally and internally is a roughness;

Adopt the PCB wiring board to be electrically connected between the described module;

Described driving power is fixed in the lamp holder.

The beneficial effects of the utility model: the utility model has adopted led module as light source, with respect to single led light source independently, is electrically connected simplyr, and performance is more stable, and it is convenient that processing is installed.Lamp housing adopts the cavity structure design, and surface irregularity has effectively increased area of dissipation, has improved radiating effect, and lamp housing can adopt aluminium alloy extruded moulding, and technology is simple, and is with low cost.The utility model is simple in structure, function admirable, and good looking appearance can substitute existing fluorescent lamp fully.

The specific embodiment

See also its implementation process of description of drawings:

As Fig. 1, Fig. 3, shown in, the present embodiment outward appearance is made up of lamp housing 1, lampshade 2, lamp holder 3, contact pin 6, screw 8.Its overall appearance is all size fluorescent lamp of standard, can directly replace with existing various fluorescent lamps.The surface of lamp housing 1 is provided with numerous projectioies, and to increase the lamp housing area of dissipation, lampshade 2 and lamp housing 1 are arc for the cross section, lampshade 2 and lamp housing 1 are formed a complete cylinder type structure, be connected with lamp holder 3 at two ends by screw 8, fixing plug pin 6 and outside are electrically connected on lamp holder 3.

As Fig. 2, shown in Figure 3, present embodiment is made up of lamp housing 1, lampshade 2, lamp holder 3, led module 4, driving power 5, contact pin 6, screw 7, screw 8.Wherein, led module is fixed on the inner surface of lamp housing 1, described inner surface be exactly camber line near surface is exactly an inner surface from the center of circle, otherwise be outer surface, led module is undertaken closely fixing by screw 7.When fixed L ED module 4, generally can be in fixing contact surface coating heat-conducting glue, the contact area on raising module and plane.By closely arranging, each electrode interconnects between the high-power LED module 4.Lampshade 2 is fixed on the lamp housing 1, and wherein, lampshade 2 also can replace with lens.Connect by screw 9 between lamp housing 1 and the lamp holder 3, be provided with the two ends that 5, two contact pins 6 of power supply respectively are fixed on lamp holder 3 at lamp holder 3 inner two ends.

In Fig. 3, lamp housing 1 is aluminium alloy extruded formation, also can adopt metals such as copper, aluminium to form by other modes.Be provided with two cavitys 11 in the inside of lamp housing 1, its number can be carried out conversion as required, is orderly concavo-convex on the surface of housing 1 and cavity 11, to increase the area of dissipation of housing 1.Center, place, plane at housing 1 is provided with groove 12, is used to hold fixed L ED module 4, is provided with several through holes 41 in led module 4, and screw 7 is fixed on led module 4 in the groove 12 by through hole 41.Be provided with latch 13 in both sides, lamp housing 1 plane,, make being fixed together that lamp housing 1 and lampshade 2 can be tight, firm corresponding to the slot 21 of lampshade 2 both sides.

The cavity that lamp holder 3 is provided with two louvres 31 and lamp housing 1 fuses.Different selections can be carried out according to different needs in the number of louvre 31, size and position, can keep cavity 11 inner good air to flow.Driving power 5 is installed in lamp holder 3, present embodiment can directly be used under the civil power situation, also can be according to the actual needs, driving power is external.Screw 8 passes the screw 32 in the lamp holder 3, and lamp holder 3 and lamp housing 1 are connected to one.Contact pin 6 is fixed on jack 33 places of lamp holder 3, so that be electrically connected with the outside.
