Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] For a structural schematic diagram of the preferred embodiment 1 of the lamp cap of the present invention, see figure 2 . The lamp cap includes a reflector 1, a light source 2 installed at the bottom of the reflector 1, a cone 3 with reflective function installed on the front of the light source 2 in the irradiation direction, and the apex facing the side of the light source 2. The bottom angle of the cone 3 is 50 degrees. The axis of the cone 3 coincides with the axis of the reflector. The inner surface of the reflector 1 is coated with a high-reflection film to improve the reflectivity of the reflector to the light of the light source 2; the light source is emitted through the inner surface of the reflector 1 to form the focus brightness of the lamp head; the light source 2 is an LED energy-saving light source; the side of the cone 3 has The...

Abstract

The invention relates to a lamp head, which comprises a reflecting cover and a light source positioned at the bottom of the reflecting cover, wherein a round table or a circular cone with a reflecting function at the lateral side is arranged right in front of the irradiation direction of the light source, the top surface of the round table or the vertex of the circular cone is right against the light source, the axial line of the round table or the circular cone is coincident with the axial line of the reflecting cover, the lamp head also comprises a lamp surface cover arranged on the top of the reflecting cover, the round table or the circular cone is a transparent cone body, the center part of the round table or the circular cone is made into a hollow structure, and the round table or the circular cone and the lamp surface cover are in an integral structure. The lamp head has the advantages that because of the arrangement of the round table or the circular cone with a radiation function at the lateral side, the wide angle of the lamp head can be increased without weakening the focusing intensity of the lamp head; because the round table or the circular cone are made into the hollow structure, the focusing intensity of the lamp head can be enhanced; and because the round table or the circular cone and the lamp surface cover are in the integral structure, the processing and the installation are very convenient, the cost is low, and the economic benefits are very good.

Description

【Technical field】 [0001] The invention relates to an illuminating device, in particular to an illuminating lamp holder. 【Background technique】 [0002] At present, portable lighting lamps, such as portable flashlights, industrial and mining lamps, searchlights and other lighting devices, require a strong focus brightness and a large wide-angle. In the prior art, in order to increase the wide angle of illumination, it is necessary to change the curve of the inner surface of the reflector of the lamp head of the lighting device. After changing the curve of the inner surface of the reflector, although the wide angle of the lighting device is increased, the focusing brightness of the lighting device is reduced, which is serious. The performance of the lighting device is affected; in order to obtain stronger focus brightness, the wide angle of the lighting device will be smaller. [0003] see figure 1 The lamp cap includes a reflector 1 , a light source 2 installed on the botto...
