Abstract
The utility model discloses an electrical reflector lamp, which comprises a lamp body, a lamp head and a light source, wherein the lamp body are confluenced by a necked lamp body portion, a first reflecting barrier portion, a second reflecting barrier portion and a light transmission window, the inner surfaces of the necked lamp body portion, the first reflecting barrier portion, the second reflecting barrier portion of the lamp body are equipped with a layer of metal reflecting coating, the first reflecting barrier portion is a paraboloid which an axis and the axis of the lamp body are coincided, and the second reflecting barrier portion is an axisymmetric body of an arc line segment. The inner surface of the lamp body uses a special frosted process milled sand, the surface is rough, but the particles are superfine, the curvature is small, pliable and flat, thereby the light both has a refraction characteristic and has a transmission characteristic, the distribution of the light is uniform, the luminousness of the light transmission window is improved. The beam of the light transmission window of the electrical reflector lamp is superimposed, the light intensity is two times a common electrical reflector lamp and is three times an incandescent lamp, simultaneously the utility model is capable of keeping an excellent beam uniformity.
Description
Technical field
The utility model relates to a kind of electric reflector lamp.
Background technology
Existing electric reflector lamp comprises lamp housing, lamp holder and light source, described lamp housing is merged by neck shape lamp housing part, first reflecting wall part, second reflecting wall part and optical transmission window, the free end of neck shape lamp housing part supports lamp holder, axis lead-in conductor from lamp holder along lamp housing, connect light source, the geometric center of light source is arranged on the focus that first reflecting wall part had, the rough inner surface of lamp housing, and the inner surface of the neck shape lamp housing of lamp housing part, first reflecting wall part and second reflecting wall part has the layer of metal reflectance coating.
CN 1127032A discloses a kind of electric reflector lamp, wherein first reflecting wall partly is paraboloidal, and having first axle with the dead in line of lamp housing, second reflecting wall part then is one section parabolical revolving body, and has second axis that surrounds the α angle with the axis of lamp housing.Because the columnated light beam that annular beam that second reflecting wall part is shaped to and first reflecting wall part are shaped to does not have superposition, though obtained the light beam of broad, does not improve intensity of illumination.
Summary of the invention
The purpose of this utility model provides a kind of electric reflector lamp as described below, it comprises lamp housing, lamp holder and light source, wherein lamp housing is by neck shape lamp housing part, the first reflecting wall part, second reflecting wall part and optical transmission window merge, the free end of neck shape lamp housing part supports lamp holder, axis lead-in conductor from lamp holder along lamp housing, connect light source, the geometric center of light source is arranged on the focus that first reflecting wall part had, the rough inner surface of lamp housing, and middle part to the first reflecting wall part of the neck shape lamp housing of lamp housing part and the inner surface of second reflecting wall part have the layer of metal reflectance coating, and first reflecting wall partly is the parabola that the axis of axis and lamp housing coincides.This electric reflector lamp can improve intensity of illumination greatly, keeps good beam uniformity simultaneously.
For realizing this purpose, the technical solution of the utility model is: second reflecting wall partly is the revolving body of a circular arc line segment, and the center of circle of this circular arc is just on the axis of symmetry that lamp housing had.The surface particles of lamp housing with rough inner-surface is fine, sharpness is low, curvature is little and slick and sly smooth.
The electric reflector lamp that the utility model relates to, first reflecting wall part that is the paraboloidal bending will derive from light source and reflex to optical transmission window with second reflecting wall that is the bending of sphere shape light partly; The light that second reflecting wall part that is the bending of sphere shape will derive from light source reflexes to the first reflecting wall part that is the paraboloidal bending, reflexes to optical transmission window again through first reflecting wall part then.The light beam of optical transmission window is through stack, thereby intensity of illumination greatly improves.Lamp housing has coarse inner surface, has kept making the existing refraction of light that the characteristic of transmission is arranged again, and light is evenly distributed; Because adopt the frosted of particular abrasive technology, surface particles is fine, sharpness is low, curvature is little and slick and sly smooth, has improved the light transmittance of optical transmission window, thereby has further improved intensity of illumination.
Description of drawings
Accompanying drawing is a kind of embodiment of the present utility model, and wherein part is cutd open figure for axle, and part is a side view.
The specific embodiment
Be a kind of embodiment of the present utility model as shown in drawings, the electric reflector lamp among the figure has lamp housing 1, lamp holder 8 and light source 6.Lamp housing 1 is merged by neck shape lamp housing part 2, the first reflecting wall part 3, the second reflecting wall part 4 and optical transmission window 5.The free end of neck shape lamp housing part 2 supports lamp holder 8.1 axis of symmetry 9 lead-in conductors that had from lamp holder 8 along lamp housing connect light source 6, and the geometric center of light source 6 is arranged on the focus that the first reflecting wall part 3 had.Middle part to the first reflecting wall part 3 of the neck shape lamp housing part 2 of lamp housing 1 and the inner surface of the second reflecting wall part 4 have layer of metal aluminized coating 7.The first reflecting wall part 3 is parabolas that the axis 9 of axis and lamp housing 1 coincides.
The second reflecting wall part 4 is revolving bodies of a circular arc line segment, and the center of circle of this circular arc is just on the axis 9 that lamp housing 1 is had.
Lamp housing 1 has coarse inner surface through the frosted of particular abrasive technology, but surface particles is fine, sharpness is low, curvature is little and slick and sly smooth.
The parabola of the first reflecting wall part 3 has the focal length of 20mm, revolution and constitute the center of circle and the focus 6mm apart of the circular arc of the second reflecting wall part 4.
When this electric reflector lamp work, first reflecting wall part that is the paraboloidal bending will derive from light source and reflex to optical transmission window with second reflecting wall that is the bending of sphere shape light partly; The light that second reflecting wall part that is the bending of sphere shape will derive from light source reflexes to the first reflecting wall part that is the paraboloidal bending, reflexes to optical transmission window again by first reflecting wall part then.The light beam of optical transmission window is through stack, thereby intensity of illumination greatly improves.Lamp housing has coarse inner surface, has kept making the existing refraction of light that the characteristic of transmission is arranged again, and light is evenly distributed; Because adopt the frosted of particular abrasive technology, surface particles is fine, sharpness is low, curvature is little and slick and sly smooth, has improved the light transmittance of optical transmission window, thereby has further improved intensity of illumination.
