Description

A kind of paster LED shot-light

Technical field:

The utility model relates to the LED lighting technical field, is specifically related to a kind of paster LED shot-light.

Background technology:

Ornamental shot-light on the existing market mainly is the metal halide quartz lamp, this shot-light be wait for death the heating after luminous again, luminous efficiency is low, power consumption is big, caloric value is big, service life is short.Along with the continuous development of LED technology, the LED shot-light also appears at market in succession, and the LED shot-light has little, the long service life of power consumption, can present full color.But existing LED shot-light all adopts direct insertion LED as illuminator usually, has shortcomings such as volume is big, angle of scattering is little, uniformity of luminance difference, has still restricted the technical development of LED shot-light.

Paster LED is a kind of LED that grew up in recent years, and paster LED is exactly the meaning of surface patch light emitting diode, is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity.Wherein paster LED more is used for display screen and field of light fittings, has advantages such as volume is little, angle of scattering is big, uniformity of luminance is good, reliability is high, speed of production is fast, purposes is wide, and its glow color can be that white light is at interior shades of colour.Therefore, paster LED is applied in also becomes inexorable trend in the shot-light.

The utility model content:

The purpose of the utility model is exactly the deficiency to prior art, and a kind of paster LED shot-light is provided, and has simple in structure, advantages such as optically focused property good, thermal diffusivity good, long service life, cost are low, little power consumption.

In order to achieve the above object, the technological solution of the utility model is following:

A kind of paster LED shot-light; Form by housing and luminous plaque; It is characterized in that: luminous plaque is close to the bottom that is installed in reflector, is fixed on the bonnet, and electrode passes bonnet and luminous plaque is electrically connected fixing; Described luminous plaque is to be processed through the heat conductive silica gel encapsulation by several paster LEDs that are mounted on the circuit board, and the inner face of reflector is the reflecting surface that is the horn mouth shape.

The inner surface of described reflector is made up of a plurality of little reflectings surface, and these little reflectings surface are convex configuration.

Described luminous plaque is to be mounted on the circuit board by one group of paster LED, is prepared from the heat conductive silica gel encapsulation then, can be that serial or parallel connection connects between the paster LED.

Described housing is connected with face shield by reflector, shell, bonnet and forms, and reflector and shell can be isolating constructions, also can be one.

Beneficial effect: the utility model adopts paster LED to make shot-light; With the contrast of the shot-light of prior art, its volume and weight all is far smaller than the shot-light of prior art, heat conductive silica gel select the radiating rate of having accelerated paster LED for use; Adopt numerous little reflectings surface to constitute the inner surface of reflector; Spotlight effect is good, and the utility model is simple in structure simultaneously, power consumption is little, the life-span is long, cost is low, is fit to popularization and application.

Fig. 2 is the structural representation of luminous plaque 7 among Fig. 1.

Among the figure: 1, face shield, 2, little reflecting surface, 3, reflector, 4, shell, 5, bonnet, 6, electrode, 7, luminous plaque, 8, circuit board, 9, paster LED, 10, heat conductive silica gel.

The specific embodiment:

Embodiment: as depicted in figs. 1 and 2; A kind of paster LED shot-light is made up of housing and luminous plaque 7, and luminous plaque 7 is close to the bottom that is installed in reflector 3; Be fixed on the bonnet 5; Electrode 6 passes bonnet 5 and luminous plaque 7 and is electrically connected fixingly, and described luminous plaque 7 is to be processed through heat conductive silica gel 10 encapsulation by several paster LEDs 9 that are mounted on the circuit board 8, and the inner face of reflector 3 is the reflectings surface that are the horn mouth shape.

The inner surface of described reflector 3 is made up of a plurality of little reflectings surface 2, and these little reflectings surface 2 are convex configuration.

Described luminous plaque is to be mounted on the circuit board 8 by one group of paster LED 9, is prepared from heat conductive silica gel 10 encapsulation then, and can be that serial or parallel connection connects between the paster LED 9.

Described housing is connected with face shield 1 by reflector 3, shell 4, bonnet 5 and forms, and reflector 3 can be an isolating construction with shell 4, also can be one.
