Description

A kind of G4 light fixture with LED light source

Technical field

The utility model relates to a kind of lamp pearl, refers to especially a kind of G4 light fixture with LED light source.

Background technology

Conventional G4 light fixture is capsule Halogen lamp LED, it is the one of incandescent lamp, such lamp pearl is owing to there being the use of tungsten filament, will inevitably there is certain pollution to environment, and the Luminaire efficiency of traditional Halogen lamp LED pearl not high is also a large problem, be also the reason further developing of restriction Halogen lamp LED the service life that also has lamp.And at present LED light source is applied to and is also in development on G4 light fixture, the main cause that restriction LED light source is applied on G4 light fixture is because G4 light fixture will have enough luminosity, therefore the power of G4 wants enough large, and the bad problem of the heat radiation of G4 just displays.

Utility model content

Technical problem to be solved in the utility model is: provide a kind of luminosity large, the G4 light fixture of good heat dissipation effect.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of G4 light fixture with LED light source, comprise lamp socket, lampshade and light source module, described lamp socket is provided with and holds inner chamber, described light source module comprises substrate and the power source drive device of LED lamp pearl, crystalline ceramics, described power source drive device comprises circuit board and drive circuit, this circuit board is installed on and holds in inner chamber, on this circuit board, be provided with the pin that is connected and runs through lamp socket with drive circuit, the vertical setting of described substrate and end and circuit board are fixed; Described LED lamp pearl is fixed on a side of substrate, and this LED lamp pearl is communicated with drive circuit; Between described lampshade and lamp socket, clamp fixingly, this LED lamp pearl and substrate are in lampshade.

As the preferred scheme of one, the fixing concrete structure that clamps between described lampshade and lamp socket is: the end of described lamp socket is provided with several claws, and this claw clamps and coordinates with lampshade inner surface.

As the preferred scheme of one, described claw comprises connecting portion and lug boss, and this connecting portion is connected in lamp socket end, and this lug boss is arranged at the end of connecting portion and protrusion direction outwardly; The inner face of described lampshade is provided with the annular groove coordinating with this lug boss.

As the preferred scheme of one, described lampshade is transparent PC lampshade.

As the preferred scheme of one, described lamp socket is plastic lamp base.

Adopt after technique scheme, effect of the present utility model is: 1. because the substrate of this G4 light fixture is crystalline ceramics substrate, and this substrate vertically arranges, LED lamp pearl is a side that is fixed on substrate, therefore, LED lamp pearl utilizing emitted light can penetrate crystalline ceramics substrate, make the substrate both sides all can be luminous, under identical luminosity prerequisite, the power of this G4 light fixture reduces like this, the heat radiation of LED lamp pearl requires just to reduce like this, thereby makes LED lamp pearl adapt to use G4 light fixture; 2. this crystalline ceramics substrate coefficient of heat transfer is high, and good heat dissipation effect improves light source life; 3. due to lampshade and lamp socket clamping, LED lamp pearl is in lampshade, and the heat of the luminous generation of LED lamp pearl conducts to substrate so, and the heat of substrate is delivered in air, and between substrate lamp socket and lampshade, there is fit-up gap, and these gaps have further increased radiating effect.This G4 light fixture has utilized LED light source like this, and under equal-wattage, luminosity is larger, and radiating effect is better.

Because described claw comprises connecting portion and lug boss, this connecting portion is connected in lamp socket end again, and this lug boss is arranged at the end of connecting portion and protrusion direction outwardly; The inner face of described lampshade is provided with the annular groove coordinating with this lug boss, and therefore, clamping of lamp socket and lampshade is more firm.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the structural representation of the utility model embodiment;

In accompanying drawing: 1. lampshade 1; 2.LED lamp pearl 2; 3. substrate 3; 4. power source drive device 4; 5. pin 5; 6. lamp socket 6; 7. claw 7; 71. projections 71.

The specific embodiment

Below by specific embodiment, the utility model is described in further detail.

As shown in Figure 1, a kind of G4 light fixture with LED light source, comprise lamp socket 6, lampshade 1 and light source module, described lamp socket 6 is plastic lamp base 6, on this lamp socket 6, be provided with and hold inner chamber and pin passes hole, described light source module comprises substrate 3 and the power source drive device 4 of LED lamp pearl 2, crystalline ceramics, described power source drive device 4 comprises circuit board and drive circuit, this circuit board is installed on and holds in inner chamber, on this circuit board, be provided with the pin 5 that is connected with drive circuit and runs through lamp socket 6, this pin 5 passes hole from pin and passes with external power source and be connected; The vertical setting of described substrate 3 and end and circuit board are fixed; Described LED lamp pearl 2 is fixed on a side of substrate 3, and this LED lamp pearl 2 is communicated with drive circuit; Between described lampshade 1 and lamp socket 6, clamp fixingly, this lampshade 1 is preferably transparent PC lampshade 1, and has fire retardation, and this LED lamp pearl 2 and substrate 3 are in lampshade 1.

Wherein, the fixing concrete structure that clamps between described lampshade 1 and lamp socket 6 is: the end of described lamp socket 6 is provided with several claws 7, and this claw 7 clamps and coordinates with lampshade 1 inner surface.The number of this claw 7 is 4, and when lampshade 1 is installed, claw 7 utilizes the strain of self material to coordinate with inner surface.And for fixing more firm, described claw 7 comprises 71 of connecting portion and projections, this connecting portion is connected in lamp socket 6 ends, and it is in outward direction that 71 of this projections are arranged at end and the projection 71 of connecting portion; The inner face of described lampshade 1 is provided with and 71 annular grooves that coordinate of this projection.Like this, this annular groove has just limited projection 71 axial locations at lamp socket 6.Current conventional viscose glue bonding has been abandoned in installation between lamp socket 6 and lampshade 1, can accelerate to a certain extent heat radiation.

This G4 light fixture utilizes the substrate 3 of crystalline ceramics as LED lamp pearl 2, and like this, when LED lamp pearl 2 is luminous, the both sides of meeting substrate 3 are all luminous, under so same power, can significantly improve luminosity; Like this, just can effectively solve the contradiction between luminosity (being power) and heat radiation, in the constant situation of power, luminosity increases, thereby has reduced heat radiation difficulty, this G4 light fixture is used more reliable.
