Abstract

A light-transmissive shell capable of intensifying illuminant and wide-angle light transmission includes a lens body and an extension portion integrally extended from the lens body in a vertical direction or at an non-parallel angle to the vertical direction. The lens body includes opposed outer top and inner bottom surfaces. The outer top surface is structured as a convexity and the inner bottom surface is structured as a flat surface or an inner concavity. The extension portion includes an inner surface extending around from the inner bottom surface of the lens body and an outer surface extending around from an outer edge of the outer top surface of the lens body. An arcuate surface is formed as a joint between the inner bottom surface of the lens body and the inner surface of the extension portion. The light emitted by an illuminant is intensified through the lens body and guided into a wide-angle light through the extension portion.

Description

201211456 VI. Description of the Invention: [Technical Field] [0001] The present invention relates to a light-transmissive shell for a bulb or a lamp, and more particularly to a light-transmitting shell that can illuminate a light source and transmit light at a wide angle. [Previous 彳 · · · [0002] With the advancement of technology, lighting technology has also made great progress, from incandescent bulbs, hot cathode lamps (HCFL), cold cathode lamps (CCFL) _ until the light-emitting body ( LED), various light sources are constantly being developed. Recently, due to its advantages of power saving, small size, long life, and difficulty in damage, the light-emitting diode has also obtained one of the lamps: [0003] However, as countries have responded to the green energy policy and have set the exit time of tungsten filament bulbs, LED bulbs have gradually been included in the replacement market for traditional bulbs. Accordingly, the use of LED bulbs has gradually revealed some blind spots with conventional tungsten filament bulbs and illumination by the arrangement of plain cup lamps. For example, (1) in the light effect, life and heat dissipation structure closely related to the 'conventional tungsten wire wide-angle bulb volume limited by the heat sink caused E26, E27, B22 type tungsten color bulb type led bulb can not express the maximum tile of tungsten light bulb The brightness of 軚; (2) MR 1 6 is also the same as the prime bulb. (3) It is impossible to achieve the central glare and wide-angle light transmission exhibited by the PAR system halogen bulb (reflector cup type plus diffused light-transmissive shell). According to the above (1) and (2) items: the height of the lamp cap has been installed. If a high-illuminance lamp is used, the low-illuminance lamp will not display the required illumination. According to (3), the PAR system halogen bulbs are presented in the main projection of the long-distance kanban and large-area glare, which can highlight the main and accompanying pictures. At present, the LED light bulb of the PAR system cannot be presented in terms of brightness, illumination angle and blooming area. 1 and 2 respectively show a conventional light bulb 3 using a light-emitting diode, which is 099130952, form number A0101, page 4, total 30, 0992054269-0, 201211456, a plurality of light-emitting diodes (LEDs) including a spacer structure. , SMD, wafer) 30 [0005] 301, a substrate 302, a heat sink 3〇3, a plurality of heat sink fins 3〇4, and a driver 3〇5 of the driver base 308. The light emitting diode 301 is disposed on the substrate 302, the substrate 3〇2 is coupled to the heat sink 3〇3, the heat sink fin 304 is disposed on the heat sink 3〇3, and the driver 3〇5 is received in the bulb 3. The light emitting diode 301 is driven. The heat sink 3〇3 is divided into a plurality of grooves. The angle of the V-shaped groove 306 depends on the desired angle of illumination. The light emitting diode 301 is disposed at the bottom of the V-shaped groove 306. The bulb 3 further includes a flat or convex housing 307 disposed on top of the V-groove 3〇6. Accordingly, the bulb 3 can obtain the required angle light, but the wide-angle light cannot be obtained. Moreover, the bulb 3 cannot achieve the illumination function with both projected light and large area blooming. FIG. 3 shows another conventional light bulb 4 using a light-emitting diode, which comprises a plurality of light-emitting diodes (LED, SMD, wafer) 401 constructed by a spacer, a substrate 402, a heat sink 403, and a plurality of heat sink fins. 4〇4, a driver 405 and an r-circle provided in the driver base 408, the housing 406. The light emitting diode (LED, SMD, wafer) 401 is disposed on the substrate 402, and the semicircular housing 406 is disposed on the corresponding surface of the light emitting diode 4〇1. According to this, a wide-angle uniform projection light can be obtained. However, it is limited to the size of the tungsten bulb, which can be installed in the same size as the tungsten bulb. In addition, the maximum volume of the lamp body can not reach the tungsten bulb under the condition of light efficiency and longevity. The 100W illumination (Lux) provides the illumination angle required for reading. [0006] Therefore, how to fully display the LED (SMD, wafer) bulb size, life, illumination, angle of view and halo of the old conventional bulb, and meet the height of the set point of the bulb and get the old bulb Illumination, in order to meet the user's old habits, old entertainment venues, storefronts and wide 099130952 form nickname A0101 page 5 / total 30 pages 0992054269-0 201211456 kanban projection light illumination and light design, Such as the main light, brightness, halo, etc., is a topic that the LED industry needs to face. Because if you achieve the above objectives, you can not only fully display the old illuminance and fainting; you don't have to add luminaires and bulbs to the loss and expense caused by illuminance and fainting; such as: lamps, LED bulbs The labor costs of the wiring personnel and the additional operating expenses of the business premises due to the suspension of construction. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a light-transmitting shell capable of transmitting light from a light source to a wide-angle light.

The inner lower end surface of the convex mirror body and the inner end surface of the extension housing are provided with a matte structure. According to this, not only the positive projection light of the light source can be projected by the convex mirror body to form strong light, but the partial projection light is transmitted through the extension casing to form wide-angle light. The outer edge of the upper end surface of the convex mirror body and the outer end surface of the extension housing form a circular arc edge, and the inner end surface of the extension housing and the inner end surface of the convex mirror body form a circular arc edge, and the convex mirror can be used. The difference between the strong light projected by the body and the transmitted light passing through the extended casing is improved into uniform light, and, for example, when a plurality of LED light sources are built, a wide area of focus can be formed through the inner curved surface of the inner and lower end faces of the convex mirror body. The effect of doubling light is achieved in the strong light region of the convex mirror body. 099130952 Form No. A0101 Page 6 of 30 Page 0992054269-0 201211456 'This' can achieve the effect of illuminating the center of the light source with strong light or even several times of glare, and can form the halo required for illumination, and Because the optical structure is used to achieve strong light, under the requirement of required illumination, not only can the use of LED be reduced, but also the use of electricity can be relatively reduced, and the increase of heat can be effectively reduced, and the result of energy saving and carbon reduction can be achieved.
