Description

A kind of LED shot-light

Technical field

The utility model designs a kind of LED shot-light, especially makes a kind of LED shot-light with spotlight effect.

Background technology

Shot-light can be built room lighting atmosphere, and light can be radiated on the object that requires emphasis, and plays outstanding subjective aesthetic effect, reach give prominence to the key points, environment uniqueness, levels are rich, the strong artistic effect of atmosphere.Use osram lamp that traditional LED shot-light is practical mostly or electricity-saving lamp are as light source, but this type of bulb is low with the efficient that electric energy changes into luminous energy, use very expense electricity and not environmental protection.Led light source is a kind of new and effective light source, and LED has that volume is little, power consumption is low, long service life, environmental protection and advantage such as sturdy and durable, compares the superiority with theory and reality with conventional light source.But it is more intense that LED light is dispersed effect, if just be replaced with LED to the light source of traditional shot-light, shot-light light can cause luminance shortage because of divergence of beam; Do not reach the due effect of shot-light, certainly will will adopt great power LED if will increase LED brightness, this great power LED production cost is high; And need very expensive heat dissipation equipment supporting with it; Cause whole cost to increase, Given this, be necessary to make it be fit to adopt the light source of LED as shot-light to the structure transformation of original shot-light.

The utility model content

For addressing the above problem, the purpose of the utility model is to provide a kind of LED shot-light with spotlight effect.

The utility model solves the technical scheme that its problem adopted:

A kind of LED shot-light; Comprise lamp body and light-emitting device; Described light-emitting device comprises wiring board, welding one or more led light sources and snoot in the circuit board, and said snoot is the frustum cone structure that outer end face is big, inner bottom surface is little, and the inner bottom surface of snoot has the optically focused inner chamber that is complementary with led light source; Said optically focused inner chamber is socketed on the led light source, and snoot comprises as the transmittance section, plane of the outer end face of snoot with as the light penetrating object of snoot side; The optically focused inner chamber top relative with led light source is provided with a hemispherical condensing body.

Further, lamp body comprises fixed frame and lamp holder, and described light-emitting device is arranged in the lamp holder; Lamp holder and fixed frame have corresponding inlaid hole; Be inlaid with a rotating shaft in the inlaid hole, rotating shaft flexibly connects lamp holder and fixed frame, and lamp holder can be along the rotating shaft rotating certain angle.This design lets lamp holder make the user can adjust the light emission direction of shot-light as required along the rotating shaft rotating certain angle.

Further, the both sides of lamp body are nested with spring fitting device, and spring fitting device comprises spring pressuring plate and covers the garment bag on the spring pressuring plate.This spring fitting device lets the user just can shot-light be fixed on ceiling, wall or ground by tool using, to reach the convenient purpose that shot-light is installed.Wherein the garment bag on the spring pressuring plate can effectively be protected spring pressuring plate and the frictional force that increases spring fitting device, can improve the fixed effect of spring fitting device and make the user can more easily pull open spring leaf.

Further, the wiring board rear is connected with a radiator.As if the brightness that will further improve shot-light, need to increase the power of led light source, thereby its caloric value can increase the service life that shortens led light source greatly, therefore need connect the heat radiation of radiator confession LED luminescence unit at the wiring board rear.

Further, described radiator is a ring-type fin helical structure.The radiator structure of employing fin shapes can increase the contact area of radiator and air; The heat radiation physical efficiency is dispelled the heat quickly; This fin has certain helical structure can let the air of contact radiator have certain circulation effect; Adopt the radiator of ring-type can not only save material, and can in radiator, form the cavity that dispels the heat and further improve its radiating effect.

Further, also has a silicone grease layer between said wiring board and the radiator.Use silicone grease to come connection line plate and heat radiation physical efficiency effectively the heat of light-emitting device to be delivered on the radiator.

Further, wiring board and radiator have a louvre, and described louvre is communicated with the space at light-emitting device place and the space at radiator rear.This louvre can not only supply the power line on the wiring board to pass through, and can be communicated with the space at light-emitting device place and the space outerpace at radiator rear, and the heat in the space, light-emitting device place can be delivered to outside the lamp body through this louvre.

The beneficial effect of the utility model is: the LED shot-light of the utility model is welded with one or more led light sources in the circuit board; Each led light source all has corresponding snoot; Because of the light-emitting area of led light source is little, so the light-ray condensing that the snoot that disposes the independent relative traditional integral of snoot more can send led light source together.Snoot can be through the light-ray condensing that reflects or reflection way is sent led light source; The light that the optically focused inner chamber that is provided with in the snoot can let the led light source straight line outwards penetrate can be because of changing direction through snoot; The light that led light source is sent can gather together to a direction emission, thus the brightness that has improved the LED shot-light.Snoot adopts the structure of truncated conical shape; The condensing body both sides are the light penetrating object with reflective functions; Can let led light source can reflect through the hypotenuse structure of this light penetrating object to the light of snoot both sides scattering; Light reflected is vertical with the plane at led light source place, led light source is emitted beam penetrate along same direction, further increases the spotlight effect of shot-light.The hemispherical optically focused physical efficiency that is arranged on the optically focused inner chamber plays the effect of lens, and the light-ray condensing that effectively led light source is sent is on a bit.The LED shot-light spotlight effect of the utility model is good, does not need expensive heat dissipation equipment can realize the effect of shot-light, can save the energy effectively and reduce production costs.
