Abstract
The utility model provides a projection lamp. The projection lamp comprises a base and a lamp bracket, wherein the base is provided with a fixed bracket vertical to the base; a steering handle is fixed below the lamp bracket and is rotatably connected with the fixed bracket; the connecting position of the steering handle and the fixed bracket is provided with a bolt; a compressed spring is sheathed on the bolt; and the upper part of the lamp bracket is provided with a light emitting diode, and the lower part of the lamp bracket is provided with a circuit board. The projection lamp provided by the utility model has the advantages that the steering is flexible, and the fixation is stable; the LED (Light Emitting Diode) and the circuit board are separated, so that the influence of radiation of the circuit board to the LED is reduced; radiating holes and a radiating bodies are added on the projection lamp, so that the radiating effect is enhanced; and higher-power and more LEDs can be used.
Description
Technical field
This product relates to a kind of light fixture, particularly a kind of Projecting Lamp.
Background technology
Projecting Lamp can make the light fixture of specifying the projecting environment of illumination on the face to be illuminated, claims again spotlight.Usually, it can aim at any direction, and possesses the not structure of climate condition influence.Be mainly used in ore deposit, large tracts of land operation field, contour of building, stadium, viaduct, monument, park and flower bed etc.Therefore, the large area lighting light fixture of nearly all outdoor application all can be regarded Projecting Lamp as.The outgoing beam angle of Projecting Lamp has widely to be had narrowly, and excursion is between 0 °～180 °, and wherein light beam is narrow especially is called searchlight.Projecting Lamp can produce more heat transfer at work, affects the normal use of light fixture, even can affect the service life to light fixture.LED Projecting Lamp on the market, general LED negligible amounts, small volume and power are less, and because if LED quantity is too much, the Projecting Lamp volume will be larger, and the weight of Projecting Lamp also can be larger, and the control that turns to of Projecting Lamp lamp holder will be relatively more difficult like this.LED Projecting Lamp commonly used is to select the 1W great power LED basically, if use more high-power LED, its radiating effect is relatively poor, can't guarantee its working effect.In addition, Projecting Lamp is applied to outdoor sometimes, in order to prevent wind and weather Projecting Lamp is caused damage, and the LED Projecting Lamp is good seals all generally, also can degree affect its radiating effect on certain.
Summary of the invention
The purpose of this utility model is, a kind of Projecting Lamp is provided, and efficiently solves to produce in the work that exists in the prior art to turn to the problems such as control is difficult, heat dispersion is relatively poor.
For achieving the above object, the utility model provides following technical scheme:
A kind of Projecting Lamp, comprise base and lamp bracket, described base is provided with the fixed support perpendicular to base, described lamp bracket below is fixed with and turns to handle, described handle and the described fixed support of turning to is rotationally connected, and described handle and the described support bracket fastened junction of turning to is provided with a bolt, and cover has a compressed spring on the described bolt, the top of described lamp bracket is provided with light emitting diode, and the bottom of described lamp bracket is provided with circuit board.
Described spring one end is fixed on the described fixed support, and the other end is fixed on described turning on the handle.
The distance of described light emitting diode and described circuit board is greater than 1 centimetre and less than the length of lamp bracket.
Described lamp bracket bottom is provided with plural louvre, is provided with a radiator in the described lamp bracket.
The utility model advantage is, a kind of Projecting Lamp is provided, and turns to flexibly, and is fixing safe, and LED is separated with circuit board, reduces the impact that heat dissipation for circuit board causes LED; Add louvre and radiator at Projecting Lamp, strengthen radiating effect; Can use more high-power, more LED.

The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing, those skilled in the art is more clearly understood how to put into practice the utility model.Although should be appreciated that in conjunction with its preferred specific embodiments and described the utility model, these embodiments are intended setting forth, rather than limit scope of the present utility model.
To shown in Figure 5, comprise base 1 and lamp bracket 2 such as Fig. 1 among the figure, base 1 is provided with the fixed support 3 perpendicular to base 1, and lamp bracket 2 belows are fixed with and turn to handle 4, turns to handle 4 and fixed support 3 to be rotationally connected.The angle of change and fixed support 3 after turning to handle 4 to rotate after angular adjustment is finished, needs this angle is fixed.
Turn to handle 4 and the junction of fixed support 3 to be provided with a bolt 5, cover has a compressed spring 6 on the bolt 5, and spring 6 one ends are fixed on the fixed support 3, and the other end is fixed on and turns on the handle 4.Be respectively equipped with a spring groove on the handle 4 with turning on the fixed support 3, described two spring grooves each other position are corresponding, are used for spring 6 compression and fixed positions.After angular adjustment was finished, spring 6 gross distortions remained outside tension force, had increased the frictional force that turns between handle 4 and the fixed support 3, so that turn to handle 4 can not slide, lamp bracket 2 can be not sagging yet.Turn to handle 4 to be provided with angle scale 11, can help the user to judge the elevation angle size of lamp bracket 2.
The top of lamp bracket 2 is provided with light emitting diode 7, and the bottom of lamp bracket 2 is provided with circuit board 8.The distance of light emitting diode 7 and circuit board 8 is greater than 1 centimetre and less than the length of lamp bracket, this distance enough far after circuit board 8 generates heat, can not have influence on the normal operation of light emitting diode 7.Lamp bracket 2 bottoms are provided with plural louvre 9, are provided with a radiator 10 in the lamp bracket 2, and radiator 10 is between light emitting diode 7 and circuit board 8, and radiator 10 is made for aluminium alloy, nestles up the sidewall of lamp bracket 2, help the light fixture quick heat radiating.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
