Abstract
The utility model provides a thin-type high-brightness electronic police flash lamp. The electronic police flash lamp comprises a lamp and a reflecting bowl, and the electronic police flash lamp is characterized in that a plane mirror cover with a Fresnel lens on the central part is arranged on a bowl opening of the reflecting bowl, and the diameter of the Fresnel is determined according to the aperture of the reflecting bowl; and the center of the lamp, the reflecting bowl and the Fresnel lens stays on the same optical axis. By adopting the reflecting bowl structure, the appearance structure is thin, the local Fresnel lens enables the light reflected by the reflecting bowl to directly radiate a target without changing the direction, the Fresnel lens on the central part refracts the scattered light on the central part of the lamp to be focused on the illumination target, so that the utilization rate of the optical energy is high, the optical spots on the illumination target are uniform, and convenience in installation can be realized.
Description
Technical field
The utility model relates to, especially a kind of slim high brightness electronic police flash lamp.
Background technology
The electronic police flash lamp has a wide range of applications in the control of traffic and road of today; The electronic police flash lamp of prior art has two kinds of forms; It is a kind of that to be reflector reflex to the light of lamp on the irradiation target; Another kind is to place a Fresnel Lenses at the certain distance of lamp, with the convergence of rays of lamp on the target of irradiation.The electronic police flash lamp profile of reflector is thinner, and some is not used light energy, and the brightness in the certain distance irradiated area is lower; The electronic police flash lamp profile of lens is longer; Inconvenience is installed, and the brightness in the certain distance irradiated area is higher, but inhomogeneous.
Summary of the invention
The purpose of the utility model provides a kind ofly both can be utilized light source fully, can make the higher slim high brightness electronic police flash lamp of brightness in the certain distance irradiated area again.
Said slim high brightness electronic police flash lamp; Comprise reflector and the lamp that is arranged in the reflector; It is characterized in that: the rim of a bowl at reflector is provided with the level crossing cover that central part is a Fresnel Lenses, and the center of said lamp, reflector and Fresnel Lenses is on same optical axis.
Said reflector is the ellipsoid reflector, and lamp is arranged on the along of ellipsoid reflector.
Said Fresnel Lenses is a round lens, and the angle that forms between the focus of ellipsoid reflector and the Fresnel Lenses two-end-point is 45-55 °.
The utility model operation principle: reflector is an ellipsoid; Lamp is arranged on first focus of ellipsoid; The irradiation target is placed on second focus of ellipsoid; Lamp converges to the irradiation target to the light of reflector emission by the ellipsoid reflection, and lamp converges to the irradiation target to the light part of the irradiation target direction emission Fresnel Lenses through reflector the rim of a bowl center.
The utility model adopts the reflector structure; Its contour structures is thinner; Local Fresnel Lenses makes the light by the reflector reflection not change direction direct irradiation target, and the core Fresnel Lenses converges to the irradiation target with the scattered beam refraction of lamp core, so the efficiency of light energy utilization is high; Irradiation target place hot spot is even, easy for installation.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the slim electronic police flash lamp of a utility model optics principle schematic.
Among the figure: 1-lamp, 2-reflector, 3-Fresnel Lenses, 4-level crossing cover.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.Among Fig. 1; Said slim high brightness electronic police flash lamp; Comprise reflector 2 and the lamp 1 that is arranged in the reflector, it is characterized in that: the rim of a bowl at reflector 2 is provided with the level crossing cover 4 that central part is a Fresnel Lenses 3, and the center of said lamp 1, reflector 2 and Fresnel Lenses 3 is on same optical axis.
Said reflector 2 is the ellipsoid reflector, and lamp 1 is arranged on the along of ellipsoid reflector.
Said Fresnel Lenses 3 is a round lens, and the angle that forms between the focus of ellipsoid reflector and Fresnel Lenses 3 two-end-points is 45-55 °.
During the work of the slim electronic police flash lamp of the utility model; The irradiation target is placed on second focus of ellipsoid; Lamp 1 converges to the irradiation target to the light of reflector 2 emission by the ellipsoid reflection, and lamp 1 converges to the irradiation target to the light part of the irradiation target direction emission Fresnel Lenses 3 through reflector the rim of a bowl center.
