Description

A kind of light fixture

[technical field]

The utility model relates to a kind of lighting device, especially refers to a kind of light fixture.

[background technology]

Semiconductor lighting is because having energy-saving and environmental protection, responding the fast developments of advantage such as fast.In room lighting field, LED daylight lamp fixture is with its energy-conservation advantage, and the traditional fluorescent-lamp-type daylight lamp fixture of forward is initiated challenge, constantly replaces the latter.The overall structure of existing LED fluorescent lamp can be divided three classes: the first kind is that plastic lamp shade adds aluminium radiator, on a strip aluminium radiator, fix an aluminium base, then on aluminium base, fix some LED light sources, then plastic lamp shade is fixed on strip aluminium radiator, then carries out the connection of circuit.The advantage of this class LED fluorescent lamp is technology maturation, and threshold is lower.But shortcoming is also obvious: be mainly that cost is high, be generally positioned in addition the diameter place of LED fluorescent lamp due to light source, make its space luminescence angle also less than normal, do not reach the lighting angle of conventional fluorescent type daylight lamp fixture.Equations of The Second Kind is that wiring board adds plastic cement pipe, plastic cement pipe is bicolor co-extrusion, the semicircle of pipe or 2/3rds circles are printing opacity cover, some LED light sources are fixed in the circuit board, wiring board is fixed on aluminium radiator, has groove fixing circuit board on aluminium radiator, then radiator is fixed in bicolor co-extrusion pipe, fixed by co-extruding tube inside groove, finally carry out the connection of circuit.Although this class LED fluorescent lamp lighting angle increases, cost is higher.The 3rd class is to use glass lamp, but glass lamp is easily broken, and stability and security are low, meanwhile, because the light transmittance of glass lamp is very high, can produce dazzle with the LED fluorescent lamp of glass lamp.

Therefore,, in order to overcome above-mentioned defect, be necessary to provide a kind of improved light fixture.

[utility model content]

The purpose of this utility model is to provide a kind of light fixture.

To achieve these goals, the utility model adopts following technical scheme: a kind of light fixture, and comprise glass lamp and be positioned at the light source of glass lamp inside, described light fixture also comprises the protective cover that is coated on glass lamp outer wall.

Preferably, described protective cover is made up of elastomeric material.

Preferably, the elastic modelling quantity of described elastomeric material is 0-2.14MPa.

Preferably, described protective cover is silica gel sleeve.

Preferably, the light transmittance of described silica gel sleeve is 70%-95%, and mist degree is 0.2%-99%.

Preferably, described light fixture also comprises the substrate of radiator and supporting light sources, and described substrate is installed on radiator inside.

Preferably, described light fixture comprises the end cap that is positioned at two ends, and described radiator is connected with described end cap clamping, and described radiator is by being fixed in described light fixture with the mode of described end cap clamping.

Preferably, what the glass lamp of described light fixture was hollow is cylindrical, and described protective cover is cylindrical around with the hollow of described glass lamp outer wall.

Compared to prior art, the utility model lamp has the following advantages: safe and reliable and difficult generation dazzle.

Fig. 2 is the sectional perspective exploded view of the utility model light fixture.

[specific embodiment]

Please refer to shown in Fig. 1, a kind of light fixture 1, comprises glass lamp 10 and is positioned at the light source 12 of glass lamp 10 inside.Light fixture 1 also comprises the protective cover 11 that is coated on glass lamp 10 outer walls.Because protective cover 11 is coated on glass lamp 10 outer walls, glass lamp 10 is difficult for broken.And in the time that glass lamp 10 is broken, owing to there being the protection of protective cover 11, making glass fragment not understand outer spattering, thereby both guaranteed the low cost of light fixture 1, improved again stability and the installability of light fixture 1.Meanwhile, protective cover 11 can also reduce or eliminate the dazzle of light fixture 1.

Protective cover 11 is made up of elastomeric material.In the present embodiment, the elastic modelling quantity of elastomeric material is 0-2.14MPa, and protective cover is silica gel sleeve, and the light transmittance of silica gel sleeve is 70%-95%, and mist degree is 0.2%-99%.In other embodiment, the elastic modelling quantity of elastomeric material also can change as required, and the light transmittance of silica gel sleeve also can be adjusted as required.

Light fixture 1 also comprises the substrate 14 of radiator 13 and supporting light sources 12.Substrate 14 is installed on radiator 13 inside.

Light fixture 1 also comprises the end cap 15 that is positioned at two ends, and radiator 13 is connected with end cap 15 clampings, and radiator 13 is by being fixed in light fixture 1 with the mode of end cap 15 clampings.Radiator 13, by being fixed in light fixture 1 and making radiator 13 not need to be fixed in glass lamp 10 by adhesive again with the mode of end cap 15 clampings, makes installation become more convenient.In the present embodiment, end cap 15 has shackle member 150, and shackle member 150 has draw-in groove (not label), and radiator 13 is connected in the draw-in groove of shackle member 150.In the present embodiment, more firm for what fix, the radiator of light fixture 1 also comprises screw fixed part 16, and end cap 15 also comprises screw 151, thereby screw 151 inserts in screw fixed part 16, radiator 13 is fixed more firm.In other embodiment, snap fit also can be realized by other structures, also can not need screw 151 fixing, or also can increase the fixed forms such as glue is fixing.

What the glass lamp 10 of light fixture 1 was hollow is cylindrical, and protective cover 11 is cylindrical around with the hollow of glass lamp 10 outer walls.It is luminous that columniform glass lamp 10 and protective cover 11 make light fixture 1 to realize wide-angle.

In the present embodiment, protective cover 11 is directly enclosed within on glass lamp 10, and in other embodiment, protective cover 11 also can be one-body molded with glass lamp 10.

Should be noted that, embodiment of the present utility model has preferably implementation, and not the utility model is done to any type of restriction, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement to change or be modified to the effective embodiment being equal to, in every case do not depart from the content of technical solutions of the utility model, any modification or equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
