Abstract

The utility model discloses a uniform lighting device which comprises a light source, a lens and a reflector, wherein the light source is arranged on the bottom of the reflector, and the lens covers the light source. The light emitting angle and effect of the lighting device are similar to those of a traditional spotlight through the light distribution achieved by the combination of the reflector and the lens. Light emitted by the lens in an area light source mode is deflected on the reflector to avoid direct lighting, and then effective lighting is achieved through the aggregation of the reflector. The light emitting effect and the lighting effect of the whole device are as good as those of the traditional spotlight.

Description

The even lighting device of a kind of illumination

Technical field

The utility model belongs to lighting technical field, relates in particular to the even lighting device of a kind of illumination.

Background technology

At present, the LED shot-light is in order to replace traditional shot-light, all require the rising angle of LED shot-light less than 60 degree, and the low-angle of realizing the LED shot-light is luminous, industry generally adopts the independent mode of lens or glow cup, though these two kinds of methods all can reach desired lighting angle, but still has following defective: the optically focused mode that adopts lens, can reach the light intensity of original traditional shot-light, but the less than normal and traditional illumination effect of the luminous point of lens differs greatly, and adopts the mode of reflector optically focused, Lamp cup illumination effect and traditional shot-light approach, but be subject to the bright dipping mode of LED, core is by the LED direct projection, and light does not pass through effective polymerization, central light strength fails to substitute fully traditional shot-light far below traditional shot-light.

The utility model content

The purpose of this utility model is in order to provide a kind of spotlight effect good, the even lighting device of illumination that lighting angle and effect and traditional shot-light approach.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme, provides a kind of illumination even lighting device, comprises light source, lens, reflector, and described light source places the bottom of transmitter, and light source is stated in described lens cap residence.

Also comprise base, and lamp holder, described base carries described reflector, and lamp holder is fixed under the base.

Also comprise the heat radiation shell, described heat radiation valve jacket is located at the reflector outer wall.

Wherein, described reflector bottom and described heat radiation shell joint synapsis are provided with aluminium base.

Wherein, described light source is led light source.

Wherein, described led light source is many small size LED combinations.

The beneficial effects of the utility model are: by the luminous intensity distribution that mutually combines of described reflector and lens, the lighting angle of lighting device and effect and traditional shot-light approach, lens will be with the luminous light of area source mode, deviation is to reflector, avoid the light direct projection, then by the polymerization of reflector, realize effectively irradiation, whole device go out light effect and radiation response, can both replace traditional shot-light.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1, the even lighting device of a kind of illumination of present embodiment comprises light source 1, lens 2, reflector 3, and described light source 1 places the bottom of transmitter, and described lens 2 cover described light source 1.The utility model, described lens 2 play diffusion, reflection and refraction, described lens 2 will go out light with area source 1 mode light, deviation is to reflector 3, avoid the light direct projection, then by the polymerization of reflector 3, realize effectively irradiation, deviation lens 2 and reflection unit combination reach even lighting effect.The improvement of this embodiment has, and described light source 1 adopts led light source, and the light that described led light source can send for single LEDs also can be for many small size LED combine, and described LED is SMD, and the light that sends by LED forms area source.Consult Fig. 2 to Fig. 4, it is the light emitting structures schematic diagram of the even lighting device of illumination of the present utility model, and by the even lighting device of this illumination, the front looks it all is bright.

The improvement of above-mentioned embodiment has, and the equal and lighting device of described illumination also comprises base 4 and lamp holder 5, the described reflector 3 of described base 4 carryings, and lamp holder 5 is fixed under the base 4.

One preferred embodiment in, also comprise the heat radiation shell 6, described heat radiation shell 6 is sheathed on reflector 3 outer walls.By heat radiation shell 6, can promote reflector 3 heat radiations, guarantee reflector 3 good working environment, make its durable more.

The improvement of above-mentioned embodiment has, and described reflector 3 bottoms and described heat radiation shell 6 contact positions are provided with aluminium base 7.By described aluminium base 7, make the heat of transmitter bottom can be passed to the heat radiation shell faster.

The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
