Description
Technical field
The present invention relates to lighting areas, and in particular to a kind of high intensity searchlight.
Background technique
The structure used in traditional auto lamp, searchlight and headlamp, as shown in Figure 1, mainly including LED light 4 and anti-
Photo structure, for the structure that reflective structure uses for paraboloid, which is the throwing formed with parabola along 360 degree of center axis rotation
LED light 4 is mounted in the focus of central axis by object plane mirror, the opening of the head of LED light 4 towards reflective structure.When LED light 4 is sent out
Light time, since LED light 4 is mounted in focus, the light that LED light 4 issues projects after paraboloidal mirror reflects, the light of the injection
It is parallel with central axis.
Using this kind of mode, there are the following problems, and first, since 4 luminous intensity of LED light is distributed as, perpendicular to central axis light
The angle of line luminous intensity highest, light and central axis is bigger, then light intensity is weaker.So LED light 4 is photoemissive and central axis
Angle belongs to the strongest light of light intensity 0-30 degree, but since the light in the angular range cannot be radiated at parabolic
On line mirror surface, therefore, which goes out, and is wasted.And LED can be irradiated on paraboloidal mirror, parabolic
The angle of the light that face mirror reflects away, light and central axis is necessarily greater than 60 degree, and therefore, the part light intensity is not high,
The light irradiation distance reflected away by paraboloidal mirror is not far.
In traditional searchlight, LED lamp structure is used, if to increase the intensity and irradiation distance of light, is only increased
LED light power, but after LED light power is done greatly, it is necessary to heat dissipation problem is solved, otherwise, is easy to burn out.
Meanwhile using traditional LED lamp structure, in order to increase light intensity using plurality of LEDs lamp carry out using, it is inefficient,
Because focal point can only place a LED lamp, other LED light can only be with respect to focal shift, therefore, cannot using plurality of LEDs lamp
It is sufficiently effective to utilize luminous energy.
To solve the above-mentioned problems, a kind of high-intensitive searchlight is proposed.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of high-intensitive searchlight, specific technical solution is as follows:
A kind of high intensity searchlight, it is characterised in that: including shell (1), heat conducting pipe (8) and light transmitting sheet (5), the shell
(1) it is cylindrical structure open at one end, is equipped with light transmitting sheet (5) in the open end of institute's shell (1), heat conducting pipe (8) edge
It is axially mounted to the middle part of the shell (1)；
The shell (1) is along the circumferential direction divided at least two chambers by partition (9), and the partition is located at the shell
(1) between the heat conducting pipe (8)；
Reflective mirror curved-surface structure (2) and LED light (4) are separately installed in each chamber, which utilizes
Reflective mirror curved-surface structure (2) reflection light；
The reflective mirror curved-surface structure (2) around the central axis by revolving to take the parabolical half along parabolical central axis
The radian for turning to be less than or equal to corresponding chamber is formed；
The LED light is mounted on the indoor heat conducting pipe of chamber (8), which is located at the reflective mirror curved-surface structure
(2) focus, the inner surface of the top of LED light (4) towards reflective mirror curved-surface structure (2).
To better implement the present invention, may further be: the central axis of the LED light (4) is located at the reflective mirror curved surface knot
The plane of symmetry of structure (2).
Further: the central axis of the LED light (4) is located at the plane of symmetry of the reflective mirror curved-surface structure (2).
Further: the central axis of the central axis of the LED light (4) and the reflective mirror curved-surface structure (2).Due to
LED light 4 is photoemissive to belong to the strongest light of light intensity in 0-30 degree with central axis angle, using this kind of structure setting,
So that the light in the angular range be effectively radiated in parabolic mirror along be parallel to central axis direction project.
Further: the reflector (6) is installed in bottom in shell, and the reflector (6) is adjacent with the LED light (4)
Setting, the reflective inner surface of the reflector (6) is towards LED light (4).
Further: the reflector (6) uses curved-surface structure or planar structure.
Further: the reflective inner surface of the reflector (6) is towards the closed end of shell.
Further: secondary condensation lens (7) are installed on the LED light (4).By increasing secondary condensation lens,
After light refraction optically focused, light angle is reduced, avoids light astigmatism, by reflective mirror curved-surface structure along parallel center
Line reflects away.
Further: the shell is along the circumferential direction three chambers, the reflective mirror curved surface by partition (9) even partition
The radian of structure (2) is identical as the radian of the corresponding chamber.The radian of each chamber is 120 degree, and each chamber is indoor anti-
The radian of light microscopic curved-surface structure is also 120 degree, since the light emitting angle of the LED that uses etc. is 120 degree, can effectively cover light
The transmitting range of line, the light that LED light irradiates are reflected away by reflective mirror curved-surface structure.
Further: being respectively red, yellow and green in three chamber indoor LED light (4) colors.
The invention has the benefit that first, multiple chambers are provided with, a LED is separately provided in each chamber
Lamp, each LED light are mounted on the focal point of corresponding reflective mirror curved-surface structure.Each chamber is as an independent system, hair
Raw damage will not influence the work of other systems.A LED lamp can only be placed in focus by solving traditional LED searchlight,
He shifts at LED light with respect to focus, cannot effectively utilize luminous energy.
Second, the focus of mirror construction is arranged in LED light, meanwhile, the central axis of the LED light and the reflective mirror curved surface
The central axis of structure.The most highlights that LED light issues are reflected away by reflective mirror curved-surface structure.Light-gathering is than tradition
The light-gathering of LED light parabolic mirror surface structure is stronger, and astigmatism is low.
Third, under same luminous intensity, relatively traditional paraboloidal mirror can accomplish that volume is smaller, reduce technique and
Reduce cost.
4th, red, yellow and blue three kinds of colors is respectively adopted in the LED light of three chambers, can be by adjusting three kinds
The state of LED light, to synthesize the color of different light.
