Description

Wall lamp

Technical field

The utility model belongs to lighting field, relates to a kind of wall lamp.

Background technology

On building, people can use light fixture that light is projected on the wall of building usually, make building can demonstrate fantasy effect at night, and this light fixture that just is used for the building lighting engineering generally is referred to as wall lamp.Praise highly under the main trend of energy-conserving and environment-protective in current society, adopting emerging light source luminescent diode is prepreerence selection, and it also is inevitable therefore adopting LED source on wall lamp.Because light emitting diode has higher requirement to working environment, and is particularly very responsive to the temperature of working environment, the heat dissipation problem during light emitting diode work is the emphasis of studying in the industry always.Similarly, for wall lamp, the heat radiation behind the employing light emitting diode also is the problem that needs solve.Existing light emitting diode is washed wall in heat radiation, generally all be by adopting Heat Conduction Material to make lamp body, the inboard of lamp body two side is provided with draw-in groove, then the light emitting diode aluminium base is inserted in the draw-in groove, aluminium base is stuck on the lamp body, aluminium base and lamp body bonded area are little and not tight in this structure, and the heat conduction is bad, and radiating effect is bad.

Summary of the invention

At the problems referred to above, the utility model provides a kind of wall lamp, and it can solve above-mentioned aluminium base and combine untight problem with lamp body, can improve the radiating effect of light fixture preferably.

In order to achieve the above object, the utility model adopts following scheme: a kind of wall lamp, comprise lamp body, be installed in aluminium base on the lamp body, side by side a plurality of LED bulbs on aluminium base, place the power drives plate of lamp body inside, and the end cap that is installed on the lamp body two ends, it is characterized in that: described lamp body is to comprise two side plates and a transverse slat and integrated strip heat conduction section bar, above-mentioned side plate and transverse slat form groove, and aluminium base is located at bottom portion of groove and directly is close to and is installed on the transverse slat upper surface; Bottom between described two side plates has a base plate, the integral body that this base plate and side plate are formed in one; Have many heat radiation ribs that extend along the lamp body length direction on the outer surface of described two side plates and base plate; On described each LED bulb a secondary optical lens is installed all; Described LED light bulb base has reflecting plate; Has LGP on the light direction of described LED bulb.

After adopting technique scheme, the heat conduction integral body that lamp body is formed in one, contacting heat radiation with the lamp body line with the edge that only depends on aluminium base in the conventional lamp compares, to be installed on the transverse slat be the contact of a kind of larger area face to aluminium base in this programme, the heat that the LED bulb produces is easy to be transmitted on the transverse slat through aluminium base, and transverse slat is the part of whole lamp body, and heat can be transmitted to quickly on all surfaces of lamp body and distribute, radiating rate is fast, and is effective.

The specific embodiment

The utility model is a kind of wall lamp, as shown in Fig. 1 and Fig. 2, it comprises lamp body 1, LED bulb 2, power supply driver 4 and end cap 3, lamp body 1 is one section integrated strip section bar, LED bulb 2 has a plurality of, be installed on the lamp body 1, power supply driver 4 places in the lamp body 1, and end cap 3 is installed on lamp body 1 two ends.As shown in Fig. 2 and Fig. 3, lamp body 1 is integrated strip heat conduction section bar, its cross sectional shape is similar to the letter " A " of a handstand, difference is that lamp body 1 bottom is flat with respect to the top of letter " A ", have two side plates 11 on lamp body 1 cross section vertical, transversely have a transverse slat 12, transverse slat 12 belows are base plates 13, side plate 11, transverse slat 12 are whole formation lamp body 1 structure with base plate 13, are processed into by one-body molded.LED bulb 2 is fixed on and forms the LED module on the aluminium base 21, and aluminium base 21 is installed on transverse slat 12 surfaces and upward and with transverse slat 12 is close to.Outer surface at side plate 11 and base plate 13 is provided with many heat radiation ribs 14 that extend along the lamp body length direction, with respect to this type of light fixture of tradition, lamp body of the present utility model is structure as a whole, surface area is relatively large, and aluminium base 21 is relatively big with lamp body 1 contact area, heat conductivility is good, and radiating effect is better.

In order to make light fixture have better optical effect, on aluminium base 21 surfaces a reflecting plate 5 is installed respectively, have a plurality of holes 51 on the reflecting plate 5, each hole 51 accommodates a LED bulb 2, the bottom of LED bulb 2 is concordant with reflecting plate 5 surfaces, the light of launching on the LED bulb 2 improper light directions is all reflexed on the normal light direction, improved the utilization rate of light, a secondary optical lens all can be installed on each LED bulb 2 simultaneously, make light more even, and LGP 6 is installed on lamp body 1, LGP 6 forms the structure of a face shield on LED bulb 2 light directions, both played the effect of protection LED bulb 2, and can further light have been become more even again, the light that light fixture projects forms the high and very uniform hot spot of a brightness on wall; In addition, because wall lamp is an outdoor lighting lamp, its waterproof ability also is a problem that can not be ignored, in the utility model, lamp body 1 is structure as a whole, waterproof effect is relatively good, at lamp body 1 two ends end cap 3 is installed, the edge of end cap 3 is coated on lamp body 1 end, installed waterproof washer 31 additional between end cap 3 and the lamp body 1, four sides of playing the LGP 6 of face shield function simultaneously all are embedded in lamp body 1 and the end cap 3, and power supply driver 4 places in the space between transverse slat 12 and the base plate 13, be positioned at lamp body 1 inside, as long as not water inlet in the lamp body 1, power supply driver 4 can be in the dry environment fully, and the access lead of power supply driver 4 is incorporated into lamp body 1 inside by water joint 8, light fixture reaches the inner state of sealing fully like this, and waterproof effect is fabulous.Installing and fixing of light fixture is equipped with two mount pads 7 in the bottom of lamp body 1 base plate 13 for convenience.
