Abstract

The utility model discloses an LED (Light Emitting Diode) reflector lamp. The LED reflector lamp comprises a panel, an inner ring, a lens, a base plate with a lamp bead, a clamping spring, a heat radiator, a power supply, a power supply box and a lamp holder, wherein the base plate with the lamp bead is fixed on the heat radiator; the lens covers rightly above the lamp bead; the upper end of the heat radiator is connected with the inner ring and the lower end of the heat radiator is in threaded connection with the power supply box; the lower end of the power supply box is in the threaded connection with the lamp holder; the power supply box is provided with a cavity and the power supply is mounted in the cavity; an LED light source is welded on a PCB (Printed Circuit Board) base plate; the PCB base plate is tightly fitted and fixed on the heat radiator; and the integrated lens is correspondingly mounted on the LED light source. The lens and the inner ring are provided with vent holes and an air convection loop is formed by the vent holes; an air ventilation cavity is formed by the lens and the inner ring so that the heat radiation effect of the reflector lamp is better; and the heat radiation effect is greatly improved so that the output efficiency of a driving power supply is improved and the work can be more stable and lasting.

Description

A kind of LED shot-light

Technical field

The utility model relates to a kind of LED shot-light.

Background technology

The development of LED lighting engineering is maked rapid progress, and begins to develop into today from eighties of last century six the seventies, has passed through the change of several generations, and LED illumination market of today takes on a certain scale, and from the upstream product to the downstream product, has formed streamlined industrial system.The LED shot-light that is used for illuminating product is because advantages such as its energy-saving and environmental protection are being accepted by people, gradually so be seen everywhere on the LED shot-light market of various scale models.Along with the raising of people's living standard, it is more extensive that people pursue, and it is good and outward appearance is more beautiful to be not only quality, the more important thing is to have potential safety hazard, is used for satisfying the practicality of people's difference occasions.

LED shot-light in the market, specification is uneven, and size is also all lack of standardization.The too high problem of existing LED shot-light ubiquity temperature, and the most of LED shot-lights on the market are in assembling process, and key position all is to fix by machine screws, has expended a lot of manpower, material resources and financial resources.

The utility model content

The purpose of this utility model is to overcome the defective that prior art exists, and a kind of good heat dissipation is provided, and is easy for installation, technology simple LED shot-light.

The technical solution adopted for the present invention to solve the technical problems is: a kind of LED shot-light, comprise panel, inner ring, lens, substrate with lamp pearl, jump ring, radiator, power supply, power pack and lamp holder, described substrate with lamp pearl is fixed on the radiator, described lens cover directly over the lamp pearl, described radiator upper end is connected with inner ring, its lower end is threaded with power pack, described power pack lower end is connected with cap screw thread, power pack has cavity, described power supply is installed in the cavity, led light source is welded on the PCB substrate, and the PCB substrate fits tightly and is fixed on the radiator, and integral type lens correspondence is installed on the led light source.Radiator is consistent with traditional AR111 overall dimensions by processing, inner ring aluminium sheet impact forging, and there is the air-vent heat loss through convection on the surface.Integral type lens and led light source, be pressed on the PCB aluminium base with disposable the revolving of gland screw thread, power pack and radiator are also by being threaded.

Further, the narrow supporting role's degree distribution curve flux requirement that substitutes traditional AR111 Halogen lamp LED is satisfied in the design of integral type optics of lens luminous intensity distribution, and is designed to integral type.Inner ring is positioned at panel by being threaded, and jump ring is assemblied on the panel by spring.

Further, have air vent at lens and inner ring, these air vents form the cross-ventilation loop, and lens and inner ring are formed a circulation of air cavity, make that the shot-light better heat-radiation effect is superior; Scribble the heat-conducting silicone grease layer at the upper surface of base plate with lamp pearl, effectively improved pyroconductivity.Because radiating effect improves greatly, also improved the delivery efficiency of driving power simultaneously, make its work better stable lasting.

Description of drawings

Below in conjunction with the drawings and specific embodiments the present invention is described in further details.

Fig. 1 is the decomposition chart of the preferred embodiment of LED shot-light.

The specific embodiment

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, describe most preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, the utility model is limited.

As shown in Figure 1, a kind of LED shot-light that the utility model provides, comprise panel, inner ring, lens, the substrate with lamp pearl, jump ring, radiator, power supply, power pack and lamp holder, described substrate with lamp pearl is fixed on the radiator, and scribble high thermal conductive silicon fat layer at its substrate, be conducive to heat radiation.Lens cover directly over the described lamp pearl, described radiator upper end is connected with inner ring, its lower end is threaded with power pack, described power pack lower end is connected with cap screw thread, described power pack has cavity, and described power supply is installed in the cavity, and led light source is welded on the PCB substrate, the PCB substrate fits tightly and is fixed on the radiator, and integral type lens correspondence is installed on the led light source.Radiator is consistent with traditional AR111 overall dimensions by processing, inner ring aluminium sheet impact forging, and described inner ring has the air-vent heat loss through convection.Because radiating effect improves greatly, also improved the delivery efficiency of driving power simultaneously, make its work better stable lasting.The narrow supporting role's degree distribution curve flux requirement that substitutes traditional AR111 Halogen lamp LED is satisfied in the design of integral type optics of lens luminous intensity distribution, and is designed to integral type.It is characterized in that: integral type lens and led light source, be pressed on the PCB aluminium base with disposable the revolving of gland screw thread, power pack and radiator are also by being threaded, and inner ring is positioned at panel by being threaded, and jump ring is assemblied in by spring to be convenient on the panel install.
